Manipulating Lisa's body, the syndicate frowned, looking around the huge underground cavern shrouded in luminous fungal light, accompanied by electromagnetic fine-tuning muscles, life energy converged, and the focus of the girl's eyes began to contract and transform at an inhuman speed, just for a moment, Lisa's eyes turned into extraordinary organs comparable to high-precision telescopes under the effect of 'electric current push', and everything from near to far could be seen.

Electricity Push - Actually, it is not a good word to call it now, because when they were in the world of Chronos, Lisa and the Fire Demon had already cultivated the electric current push passed down by Joshua to the extreme, and in the many experiences of Winterhold, they had developed a new kind of power, which could greatly enhance any quality of a person, whether it was hearing, eyesight, wrist strength, or the sense of smell could keenly smell everything within hundreds of meters.

Because they wanted to surprise Joshua, the two had not yet told Joshua the news, nor had they named the power, and now, under the effect of this enhanced electric current, the Syndicate had looked at at least five kilometers away in this gloomy underground shimmering environment, but to the fire demon's shock, it had not yet seen the end of this underground cavity.

"So big?! It seems that it is not an ordinary underground cavity, but it may really be part of the 'underground world' that adults say! ”

A slightly strange girl's voice sounded, and she could see that high at the edge of the underground world, there was a dark hole that was constantly falling sand and stones, and the glowing microbacteria around it were also dimmed, which was where everyone had dug and fell, and the syndicate looked at the end to no avail, so he could only turn his gaze back to the side: "There are fungi, insects, and I also sensed the ultrasound of bats...... There is life here, not just a dead grotto. ”

And while the syndicate was pondering and analyzing, with the cacophony of metal rubbing, the first number gradually stood up, its lower body had been transformed into a huge shield digger because of the excavation of the tunnel, and now, the silver steel wriggled like a living thing, and re-condensed into the body of a giant like armor.

"Click."

As if the sound of a switch being turned on, a pillar of light like a sharp sword appeared in the underground world, extending towards the dark space in the distance, and the huge single eye of the first number was releasing a dazzling white light at this time, shining around like a searchlight, it was also scanning the surroundings and observing the situation, but the result was the same as the syndicate's judgment: this is a huge, endless underground world with a certain amount of vitality.

On the upper floors of the rock wall and on the ground, the glowing micro-fungi were dimmed by the light of the first horn, and countless cockroach centipede-shaped insects sneaked into the back of the fungus or in the cracks of the rocks, and a large number of bats could be vaguely seen in the distance were panicking away from the light, and the syndicate noticed that these bats were smaller than their counterparts living in caves on the surface, and the skin was not black, but a dry grayish-white, with luminescent fungi sticking to the skin of these bats, flashing with different shimmers.

Not far away, there was a turbulent underground river, and the fire demon sensed that the water of the underground river was very fast, and he adjusted the focus of his eyes to observe the river itself: "The water quality is poor, there are many suspended particles, it is relatively turbid, but there are obvious metal particles...... Are there veins around? ”

The syndicate also found that the river was full of underground fish and some strange aquatic life, and it judged that the river was not a solitary stream, but part of a vast underground water cycle.

"Bats prey on insects, insects gnaw on fungi, and fungi feed on insects and bat carcass droppings...... In addition not far from the underground river, the foundation of the circulation. ”

Such a thought flashed in his heart, but the red light in Lisa's eyes was gradually fading, and the syndicate stretched out his hand, pressed it on his forehead, and said helplessly: "Are you awake?" ”

And the next moment, with Lisa's movements, there was a stiffness, the red light in the girl's eyes completely dissipated, and the somewhat strange lingua franca tone also turned into a smooth complaint: "Ahhh......hh I want to vomit! ”

"Your physical fitness is not so bad, bear with it."

In Lisa's body, the cold voice of the syndicate sounded, and it turned its head to communicate with the first number of spirits: "You can start the preliminary exploration, be cautious, maybe there are intelligent life." ”

Although there are only fungi, insects and bats on the edge of the underworld, because of the weakness of the ecological chain, the rumored powerful underground monsters should not appear, but if it is a gray dwarf and dark elf with intelligence, there are not so many restrictions, through the special ability to cultivate fungi and herbs, they can survive anywhere in the underground.

"Okay, I'll hold back......"

"Zizi, zizi." (Okay, Mr. Syndicate.) ）

The first horn's tone towards the fire demon was also very respectful, mainly because it sensed a trace of steel power belonging to Joshua from the fire demon's body, and the fire demon's life experience was indeed richer than it, so the first number did not have any psychological barriers.

In fact, from another point of view, the relationship between human beings has nothing to do with its steel element, as long as the other party is worth learning, then it will naturally be full of respect.

Because of the experience gained from walking in the dwarven gathering place for many years, the footsteps of the first horn did not shake too much, and it carried Lisa and the syndicate, walking slowly around. Because of caution, the three of them did not go too far, but took the hole where the three of them fell as the origin point to conduct a semicircular exploration.

However, it was such a short distance that surprised the three of them.

"These are symbiotic with glowing mushrooms, aren't they the 'Jilaner Crystal Grass' that has long been extinct!"

From the top of the first head, Lisa followed the coherent grooves on the first number's body, like a slide to the ground, she didn't care that she stepped on the ball like a blister-like glowing microfungus, the slime splashed, but directly came to a place that emitted strange magic fluctuations, the dragon girl opened her eyes wide, looking at the light yellow glowing grass surrounded by fungi like the queen of the arch guard, the texture was like a crystal, and exclaimed: "The ancient version of the 'Divine Grace Elixir', the 'Dragon's Blood Elixir' and the main material of 'Dragon Slaying Poison'!" I didn't expect there to be here! ”

Divine Grace Elixir and Dragon Blood Elixir, one can make people's body harden and become indestructible in a short time, and the other can make people burst out of absolute strength in a short period of time, and there are no side effects of cherishing magic potions, and dragon killing poison is just like its name, it is enough to poison the dragon, these potions are extremely difficult to reconcile, plus the substitute materials are also cherished, so the market price is extremely high, I didn't expect that there are their main materials here.

"Almost extinct."

Inside the girl, the syndicate reminded, "There are still a few in the rare plant cultivation room in Wintercastle, and these plants are too demanding in terms of light and mana concentration...... I didn't expect that luminescent fungi can naturally provide a suitable growth space, which is a big discovery that can earn credits. ”

As he spoke, the syndicate used the spirit scan, sensing similar magical fluctuations around it, and it was shocked: "Thirty, forty, sixty, ninety...... Over 100!? This is simply a natural Jilaner crystal grass cultivation base! ”

"Zizi, zizi!" (Wait, I sensed something strange about minerals!) ）

On the side, he was carefully stepping down, paying attention not to step on the first horn of the cherished magic plant, but suddenly stopped, and it used electromagnetic communication to make a surprise sound: "Zizizizi...... Zizizizizi! (Ah, it's pyroxene and silver...... And Moonlight Crystal! ）

Neither pyroxene nor silver attracted Lisa and the Syndicate who had already taken out a cultivation jar and saved a Jilaner crystal grass - as long as they brought this wild crystal grass back, they could get at least 750 credits, plus the credit for the discovery, and maybe there would be a reward for special contributions!

But after hearing the moonlight crystal, the girl raised her head instantly, and Lisa turned to look at the first number, and said at the same time as the fire demon, "Really!?" ”

The First didn't reply, it raised its hand, and pointed to a piece of ground not far away, and under a surge of magical power, through its innate ability to manipulate earth, rock, and metal, the First Horn dispersed all the dirt and rocks in an area, leaving only the veins located deep underground.

It was a beautiful crystal set in rock and silver, shimmering with a silver-blue light.

I don't blame the reaction of the two, because whether it is pyroxene or silver, in fact, there are a lot of reserves in the Northland, although silver is cherished, it is also the raw material of currency, but for the Moldavian Territory that is not poor, the greatest value may be its own good magic transmission, and pyroxene needless to say, the cheapest magic material in the world, a simple stone that can emit light, only the purest glowing glow can be used as the focus core of a large magic light cannon.

But Moonlight Crystal is different...... This kind of precious crystal that has been mined on the surface and can only be seen in the underground veins of the dwarves, is generally symbiotic with the pyroxene veins, it does not have many roles, but all of them are very important - the moonlight crystal is one of the few substances that can store life energy, holy light and magic power at the same time, its bearing capacity is extremely high, it can be used as the engine main body of large magic machinery, and it is also the rune core main material of high-level magic puppets, a slightly larger magic energy factory, The central control core of the energy transmission system must be made of moonshine crystals or high-purity glow crystals.

"Recently, because all parts of the empire are learning from Moldavia and popularizing the industrialization of magic energy, the original reserve of moonlight crystal inventory is quickly urgent, and the empire has even negotiated with several large chambers of commerce in Xishan to import it, but the price of the other party is very high!"

Because Lisa is a student of Joshua, she often contacts the soldiers through the information terminal, and she knows these things from Joshua's casual chats on weekdays, and now she has discovered the vein of Moonlight Crystal in the underground of the Northland, which is good news for the entire empire!

"Speaking of which, will crystal grass have anything to do with moonlight crystals?"

Because around the birthplace of the Moonlight Crystal Vein, there are a lot of Jilaner crystal grasses, and the names are somewhat similar, so Lisa has some guesses, but neither the first number nor the syndicate are experts in this area, so it can only be said that there is a certain possibility.

"If it's true, then it's another big discovery, compared to the common moonlight crystal, Jilaner crystal grass is really priceless."

But at this point, Lisa, the syndicate, and the first three calmed down.

"Do you want to continue to explore into the distance?"

The syndicate said in a deep voice with a spiritual communication: "We have gained so much just by exploring such a small area of a few kilometers around, whether it is the Jilaner Crystal Grass or the Moonlight Crystal Vein, it can bring a lot of money, thousands of credits and special contribution benefits...... If we really want to continue exploring the distance, we can continue to follow the river. ”

The tone of the fire demon did not approve of continuing to explore, nor did he say that he would go back immediately, after all, there might be more discoveries in the distance, and when they went back and reported to the academy, then the remaining first wave of harvest would be gone, but it was also a little dangerous to continue exploring, although according to the current situation, this danger was very slight.

It was intended to be left to Hatsu and Lisa to decide

"Zizi...... Zizi ”

(I don't know...... But the mysterious voice in my head was getting louder and louder, and it continued to call me. ）

Squatting down slightly, looking down at the dragon girl, the light released by the first one's single eye hit Lisa like a spotlight, but Lisa did not feel uncomfortable about it, and the first number said with some hesitation: "Zizi." Zizi, zizi. (I'd like to keep looking.) Sister Lisa, what about you? ）

"Needless to say."

With the somewhat confused first number completely thought, the dragon girl raised her head, her eyes widened, and she looked at the strong light of the iron giant, Lisa said loudly with a righteous face: "Of course, go back early and tell the good news to Teacher Joshua!" ”

Speaking in a rather surprising tone of firmness, Lisa then said in a tone that didn't seem like her age: "I accidentally discovered a mysterious area with a lot of treasures, and because of curiosity or greed, I kept exploring the depths, and then I became crazy and fell into danger...... This week alone, Miss Hotaru recommended me three books with similar routines! ”

INTERVIEWER What is it, and how can it become crazy just by exploring? Because he falls asleep when he's bored, the syndicate, who didn't read a book with the girl, complained silently in his heart.

"Humanity lives on an island called Ignorance in the middle of a dark ocean, an ocean of vast expanses and mysteries, but we shouldn't sail too far and go too deep – unless you're strong enough!" Repeating the content of the book, Lisa's tone was a little emotional: "Since coming to the world of McCrove and reading so many exploration and horror stories, I, Lisa, have learned a truth - that is, never do things that do not meet my own strength when my strength is not enough!" ”

- Don't learn the tone of an adult! Feeling the familiar atmosphere from the girl's words, the syndicate continued to complain in his heart.

"The mysterious voice in the mind of the first one, and the underground world that can block the mind scan of Mr. Syndicate, is extremely rich but has no end in sight, and is full of unknowns, as long as you have a little common sense, you will feel unusual...... I'm not so stupid to explore such a dangerous place alone! ”

Lisa's expression was very serious, but she could see a hint of cunning that inadvertently flashed in the dragon girl's eyes, and she continued to say with a righteous face: "What's more, these materials were all found in the underground of Moldavia, in other words, all of them are the property of Teacher Joshua, and we shouldn't have thought of taking advantage of it in the first place!" ”

“…… He must be very pleased, my lord. The syndicate was quite speechless, but then it shook its head and smiled bitterly: "Alas, I don't actually recommend continuing to explore, but I didn't expect you to come up with such a reason......"

(However, although the righteous words are too much, such a Lisa is also quite cute.) )

Running to the feet of the first number, Lisa stood on tiptoe and patted the side of the iron giant's shoe, and she said quite sincerely: "First number, just digging a hole in the ground can be regarded as entertainment, but now is not the time to play, be aware of the danger, and don't take chances." ”

"And that voice in your head, it's time to talk to the teacher."

"Zizizi...... Zizi (Although there are some regrets...... But I'll listen to you, and I'll go find an adult when I get back. ）

Hearing the voice of the dragonman girl, the iron giant hesitated for a moment, then nodded slowly, and it reached out and held the dragonman girl in the palm of his hand, and then placed it on top of his head. The first number stood up, turned, and walked towards the cavern they had come from.

"Boom ......Rumble" with a strong noise, and the first number, which was transformed into the form of a shield excavator again, took Lisa and the syndicate with him, and returned the same way.

……

In the silence of the underground world, the glowing fungus shimmered dimly, and the bats that had fled into the distance because of the bright light began to fly back to their familiar nests, using ultrasound to search for the traces of the giant alien.

Whoa......

Strange sounds rang out from the underground river.

On the surface of the turbulent and turbid underground river, black shadows suddenly appeared, these shadows were huge and deep, as if they would naturally absorb the surrounding light, and the surrounding underground fish quickly fled, but still many were swallowed by the shadows, and only light blue blood stains could be seen spreading on the surface of the river.

With the sound of the water crashing, the shadow emerged from the water, and with the light of the surrounding pyroxene and glowing fungi, its true body could be seen-

It was a huge, iron-black 'giant python', the scales of these 'giant pythons' were pitch black, their eyes were shining with light golden light, and the 'giant python' led by them was chewing an unlucky underground fish in its mouth, and between the sharp teeth rubbing, light blue blood dripped on the water.

Boom la la la————

The python slapped the water, they looked around, as if looking for something, the giant python in the lead swallowed the underground fish into its belly, then crawled to the riverbank, coiled its body, it opened its golden snake pupils, observed the movement of the surrounding space, because of the perspective, they did not notice the edge of the underground world that was not coordinated with the surrounding rock wall - the three unexpected comers before returning, intentionally or unintentionally closed the hole, and processed the surrounding traces.

So a moment later, after a silent exchange, the pythons returned to the water and continued to swim with the current into the distance.

No one knew they had come.

And no one knew they had come.

On the other side of the world, in Sequoia City, Joshua, who was playing fairy cards in a bar with Hotaru and Rin, suddenly received a message.

"What's wrong?"

Lowering his sense of existence and compressing the aura of despair to within a centimeter of his body, Joshua and the human drunkards and dwarves around him who don't know him are engaged in a pleasant gacha game, and Joshua, who is rarely entertained with everyone, is nostalgic for playing this game with his friends in his previous life, but is pulled by Hotaru and tells him that something happened.

"I'll look at ......"

Walking out of the crowd and coming to the corner of the bar, Joshua took the silver-haired girl's hand, and through the information terminal in her body and the link to the magic web in the distance, in an instant, the warrior understood why the academy was in such a hurry to contact him.

"The Underworld...... In my previous life, I had never heard of this thing in the ground of the Northland, where did this guy dig up? ”

Saying this to himself, Joshua pondered for a moment, and then said: "Tell them that the exploration mission of the underground cave continues, but the underground world is not in a hurry to explore for the time being, seal that passage, and wait for me to go back and see the situation." ”

An underworld that can be insulated from the psychic and the magic?

Squinting his eyes slightly, Joshua said softly, "Interesting." ”

And the silver-haired girl standing in front of the warrior, Hotaru was very familiar with the expression on her master's face at this time, what it represented.

That meant that the fighters were really starting to get 'curious'.
