Sean crouched on the ground, his eyes fixed on the mouth of a barely bottomless pit in front of him.

The mouth of the pit is more than three meters in diameter, and the edge is a black stone that is as hard as iron, which looks smooth but is very rough to the touch. And from the mouth of the pit down is also made of these stones, these stones are not small, completely enough for any adult to climb with their hands and feet, and even the bear man wants to climb in this pit is not a problem, but there is no bottom of this deep pit, absolutely no one dares to venture down.

Sean slowly stood up, his eyes becoming a little gloomy.

"Is it really the Abyss Path?" Cecilia saw Sean's face, and she had a little realization in her heart, but she still wanted Sean to answer in person.

The Abyss Path does not refer to a portal to the Abyss Plane.

Another plane, such as Abyss Purgatory and Hell, can only be opened by dimensional portals. And limited by the constraints of the power of the law, this kind of portal is not easy to open, even the top powerhouse as strong as a legend can't tear the space at will to build a fixed-point plane portal with his own strength, which is also why Andrew has to spend countless energy looking for things that can allow him to find the coordinates back.

Therefore, in this worldly realm, the path of the abyss usually represents only one meaning.

The path to the Underworld.

It is the world where dark elves, blood elves, crypt demons, cavemen, and many other races and monsters live. They call themselves the Underground Dwellers, and they hate all surface dwellers and creatures—or the two hate each other—so the Surface Dwellers have been trying to prevent the Underground Dwellers from appearing, and the Underground Dwellers are trying to get to the surface and make a big fuss.

Occupy the realm of the earth?

Whether or not there is such an idea, no one except the underground inhabitants knows.

"It is indeed the path of the abyss." Sean nodded, "But it's really sealed." ”

"Which side?" Tini asked.

The Abyss Path is not recognizable to everyone, but there is some common knowledge about the Abyss Path. But many people know it very well.

The Abyssal Path is a passage that connects the two worlds of the earth's surface and the underground, but it is amazing that this passage was not entirely created by man. This is a bit like a loophole in a program, but this loophole can be exploited by the residents of the two worlds, whether on the surface or underground, as long as they use some special means to continue in the opposite direction through this loophole, they can open up a passage connecting the two worlds.

It's a bit like an unstable portal or something.

And since it is a portal, it can naturally be closed.

The inhabitants of both the surface and the underground realms were able to forcibly close these passages by the same special means.

Back then, the war between the Underground World and the Underground World and the Surface World and the Earth Realm once plunged the Surface World into chaos, and after controlling the situation and counterattacking, the Underground World Realm naturally tasted the consequences. After more than a decade of war broke out between the two sides, many passages were forcibly closed or blown up by both sides. It is really not easy for the current world world to find a passage to connect the two world worlds.

And I don't know what the road is, and now there are almost no more "loopholes" in this world, and the two worlds on the surface and underground have gradually forgotten the existence of both sides. In the eyes of the children of today's era, the Underground World Realm is just a fictional illusory realm. If it weren't for Cecilia's actual face to face the Crypt Demons with Sean. I'm afraid she'll think it's just a made-up story.

"Look at the rocks around you." Sean pointed to the hard black stones around him.

Everyone looked in the direction of Sean's finger at the rocks around the crater.

"The path of the abyss that is opened, these stones emit a soft blue-white glow. These rays of light are a lot like the energy protection barrier of a portal. It ensures that people from both worlds are able to go back and forth. Sean opened his mouth to explain, "The Abyss Path without this kind of light means that the Abyss Path has been completely sealed. As for which side it was sealed, we can see here......"

Sean said, then pointed to the circle around the pit and continued, "If it is our side that seals the Abyss Path. A red circle will appear around the channel, and vice versa. …… In fact, in the final analysis, this kind of seal doesn't have any technical content, it is just to set up a pair of magic arrays. The main array is set up on the side of the sealing side, and the secondary array is set up on the other side, and then all the energy of the channel can be drained. ”

"Pumping?" Andrei looked dazed.

"Axis Transmission Magic Array Technique." Cecilia reacted immediately, "Through full control, all the energy is extracted and sealed, once the energy is drained, the secondary array will lose its value and then annihilate itself due to the collapse of the magic power, and at the same time, it can also prevent the people on the other side from reversing control." ”

"That's it." Sean nodded, "Whether it is our surface world realm or the underground world realm, we all use this technique. …… Strictly speaking, our surface people are still underground people who have learned, and it is they who first invented this kind of technical means. ”

"In this case, isn't the initiative in the hands of the party that arranged the magic array?" Andre's reaction is indeed not slow, he is worthy of being a ruthless character who can survive in the wilderness for many years, and he captures the crux of the problem at once.

"Yes, so the few sealed abyss paths that are currently known to be in the Dao, except for one that was sealed by us, the other initiatives are completely in the hands of the Underground World." Sean nodded, "For this reason, several major empires must send heavy troops to guard there. …… The Millennial Covenant Empire, do you know what the two words 'Covenant' mean in this Empire? ”

Everyone shook their heads blankly.

"Guardian meaning." Sean opened his mouth and said, "The Millennium Covenant Empire has a large dragon knight legion, and in terms of comprehensive military strength alone, it is definitely the largest among the seven empires, but why has it been relatively low in the ranking of the seven empires?" In order to keep the thousand-year covenant, they had to spend nearly half of the entire empire on defending against the invasion of the Underworld and conquering the infidels. An empire that can defend the three abyssal paths with the power of a single country, except for the Cinnas Empire, I am afraid that no empire can compare with it, but the Chaynas Empire also has congenital weaknesses. ”

"Internal partisan conquest continues." Cecilia spoke, and then suddenly saw everyone looking at her, and immediately subconsciously added: "I saw it in the book." ”

So everyone's eyes turned to Sean again.

In everyone's knowledge. Sean is a nobleman from the Cinnas Empire.

"That's true." Sean smiled and nodded, "So the Chainas Empire is already very difficult to guard the two abyssal paths, and no army or nobleman in the empire is willing to do such a thankless task." …… So basically, in the Chainas Empire, only those soldiers and nobles who have been sentenced to heavy sentences will be arranged to guard the Abyss Path, which is very different from the Thousand Year Covenant Empire. ”

"So which empire are we going to report to this abyssal path?" Tini asked, "The closest to here should be the Thousand-Year Covenant Empire, but they are already guarding the three abyssal paths, I'm afraid they can't draw troops over, right?" And the second closest to here is the Cinnas Empire, but according to what you say, it is impossible for the Cznas Empire to send troops over, right? ”

"This magic laboratory was originally the ...... of the thousand-year-old Covenant Empire"

Andrei just spoke. was interrupted by Sean: "Why do you want to report?" ”

"But if we don't report it, we won't be able to defend a passage to the underground world with our military strength." Andrei was stunned for a moment, then replied, "According to the regulations of the Peace Council, if loopholes and abyssal paths are found. Shouldn't it be reported to the nearest empire? ”

"What does the rules of the Peace Council matter to me?" Sean pursed his lips. "There are so many places where you can use this kind of passage. Who said we can't control it. As long as the channel is opened again, and then the reverse operation is operated to transmit the magic array on the axis, and the main array is set on our side, then the initiative of this channel will fall into our hands. ”

Hearing Sean's whimsical words, everyone showed a look of surprise.

"It's impossible!" The surprise on Cecilia's face quickly subsided, and then a look of questioning. "The biggest feature of the Axis Transmission Magic Array is that all the energy of the axis that set up the magic array is drained, and its casting is completely controlled by the main array, and the secondary array on this side has been automatically annihilated. And the energy has been drained, so we can't control it at all. ”

"Actually, there is a way." Sean opened his mouth and said, "As long as we re-depict a guiding magic array here, stretch the closed passage through a little gap, and then we continue to pour energy into the gap, so that the main array on the opposite side continues to absorb energy until it explodes beyond the critical point, then the sealing magic array will be completely invalidated, and the path of the abyss will be opened again." ”

Hearing Sean's words, Cecilia's eyes immediately lit up, and she was already a little eager to try.

But Sean knows very well that what he said is very simple, but it is not as simple as he imagined when it comes to actual operation. The energy output of the calculation-oriented magic array alone is a huge project, not to mention how huge the power source to support the continuous operation of the entire magic array is, even if these two points can be solved, the continuous investment of energy is definitely an astonishing overhead, but it is much simpler than the former two.

Just have money.

However, this kind of technique will never be possible until the power source of the magic guide is developed. In the game, the battle between the surface and the underground world is also the main content of the fourth expansion, and in terms of the timeline of this world, it will be ten years later.

Sean began to feel that it was necessary for him to accelerate the development of scientific research in this world.

The Underground World Realm is a real treasure trove of wealth. (To be continued.) For mobile phone users, please go to read. )

PS: This is a bit more than that, I'm sorry, mainly because my mental condition is not very good. People are really tired, I went to bed too late last night, I got up too early in the morning, and then there are a lot of things to do today, and there are guests visiting in the afternoon, and I can't stand it for a busy day, so I'll go to bed for the time being.
