It is not the first time that the dry excavation of the living forest tree, so it is quite experienced, under his command, a few tunnels were quickly opened, Lin Shu believes that this relic complex is a plane building, so the longitudinal depth is very limited, and the part that has been excavated can also see this, therefore, the tunnels are all horizontal, the main purpose is to confirm the general range of the ruins, and at the same time, when the open tunnel is filled with light and fire magic energy, the effect of the detection technique is immediately better.

Lin Shu's crew are all strong masters, digging tunnels is definitely trivial, Lin Shu's only worry is that they don't work too happily and destroy this ruin.

"Xiao Xin, how is it, can the soil be planted with orchids?"

"Yes, but it's still a bit hot, and it will be about the same when the soil temperature in the barrier drops. ”

Lin Shu waved his hand and said, "Don't wait, use an ice magic to cool down, and by the way, infiltrate the water into the soil." ”

"But with such a high ambient temperature, it will fog up, and there are no water molecules here at all, so how can ice magic be used? ”

Lin Shu shook his head: "There must be water, it's down there!"

Lin Shu didn't guess blindly, but when he performed the Star Chasing Dragon Technique, he did discover the existence of water, no, it existed underground in the form of ice.

After Lin Shu finished speaking, he looked for a place under the body of the small star ship that was not covered by metal plates, his fingers lightly drew a circle, and then he pressed it suddenly, and a pit the size of a face suddenly appeared on the ground, and then, this pit quickly extended to the ground, and the soil in the pit seemed to have disappeared strangely.

Actually, if you look closely. You can see a small whirlpool spinning rapidly on the dirt at the bottom of the cave. The rolled dirt is then quickly swept around. The high-speed flying earth slammed into the surrounding cave walls, turning them into smooth glass bodies, which showed its speed.

Li Xiaoxin blinked his eyes and looked at Lin Shu's spell, this was a throwing spell, Lin Shu had already put away his hand and was looking down at the effect of the spell.

"Husband, what kind of spell is this?"

"Uh, it's just a normal earth-based spell and make it spin. And it limits the diameter of the spell, so it's not a spell. ”

"It's very practical to use to punch holes, but if you make the diameter larger, won't you be able to open a tunnel at once?"

"That requires the energy and mental power of the progression to rise, it is better to make a temporary formation, although it takes a little time at the beginning, but at least there will be few follow-ups. ”

"Well, that makes sense, I'll design one, it's called the Earth Tunnel Construction Array. ”

Lin Shu shrugged. This formation is very simple, and there is no difficulty at all. Many times, a good spell and formation actually depends on the idea, so the ability to innovate is the most important.

After Lin Shu added a few spells, the hole was about two or three kilometers deep, and then finally came into contact with the ice, and then a fire-based spell was thrown down, and soon the melted water was lifted up from the depths of the ground, and everyone returned to the inside of the small star first, and a large amount of water vapor filled the entire enchantment, and the temperature inside the enchantment began to drop.

After everyone rested and eaten, the temperature in the enchantment had been reduced to a suitable level, and Jessie and Li Xiaoxin began to plant blue and huivine everywhere, these two plants can grow with the help of light magic energy, and at the same time absorb exhaust gas and elements in the soil to release oxygen, nitrogen, etc., which are specially used to transform the breathing environment in the confined space.

After the birth of the wood magic, soon the ground was covered with gray-green plants, and everyone no longer had to hold their breath to work, although everyone present could not need to breathe for a long time, but breathing is the instinct of carbon-based advanced life, and it is still very uncomfortable not to breathe.

"Brother, how do you know that there is underground ice under the road?"

"Guess!"

"Don't believe it!"

"It's really a guess, you think, since this was once a big city inhabited by humans, how could there be no underground water source?"

Lin Wei had to admit that this logic was tenable.

Lin Wei glanced at the triumphant forest tree, and smiled mischievously: "Since my brother is so powerful, then guess where the most important building in this complex is, and save us from spending our efforts to dig indiscriminately." ”

"Well, I was going to dig up the whole city. ”

Lin Wei rolled his eyes: "The exploration tunnel we dug is already more than ten kilometers deep, and we haven't seen the edge of the city yet, how can we dig it all?"

"Well, it doesn't seem that difficult, right? It's just a matter of time. ”

"But herein lies the problem, we don't have that much time to waste in this ruin. ”

Lin Shu thought about it and agreed with Lin Wei's idea, the value of this relic is indeed not very high, there is really no need to spend too much time here, although his contact with his family has not been interrupted, but floating in the unknown star field for a long time will definitely make the family feel uneasy.

"Okay, then guess, I'll try the soil active detection technique, everyone pay attention, there will be some vibration!"

Lin Shu used the soul link, sent a message to everyone, and received a response one by one, before he performed an earth system detection technique.

Soil detection is the detection technique with the lowest detection efficiency and accuracy, which uses an omnidirectional shock wave to obtain the reflected wave for detection, and the information obtained is quite limited.

However, Lin Shu modulated more soul power in this spell, and even simulated the mysterious fluctuation pattern of some dragon vein power, which greatly improved the detection efficiency of this spell.

After about two or three minutes, Lin Shu opened his eyes and stretched out his hand to point in a certain direction: "Let's dig in this direction, there is a very large building here, I wonder, why do humans on this planet like to live in metal rooms?"

"Brother Ha Lu Ha stupid," Lin Wei smiled happily, Lin Shu was finally caught by her when he was stupid: "This place is already underneath!"

"Uh, that makes sense, why didn't I think of that?"

Lin Wei smiled and patted Lin Shu's head and comforted: "Don't be discouraged, my brother is very powerful, hehe." ”

Three hours later, a large structure had been cleared, in fact, from the pattern of the building, it can be seen that these reinforced dome structures are obviously underground buildings, it seems that Lin Xiao's speculation is correct.

With a diameter of more than 500 meters, the circular structure is quite large, without any columns, and relies entirely on a solid dome structure, which shows that the strength of these metals is also very high.

However, after years of change and oppression, the dome was still destroyed, and now, Lin Shu used magic to build a thick shell from the soil outside the dome, and then restored most of the dome, and the damaged places naturally ignored.

The contents of the building are non-existent except for metal and stonework, which indicates that the time of death after the most demurrage of the planet is very slow, so there are traces of erosion on the metal, and if the planet is soon devoid of atmosphere and water, the erosion should stop.

Based on the age of the metal, Lin Shu determined that this civilization had disappeared for at least a million years, which was quite a long time.

"There are some words here, and from the point of view of the position, it should be very important explanatory text. ”

Lin Wei pointed to the large text on the curved wall in front of him, and said with certainty.

"Well, it's either something to do with an important event in this civilization, or it's a text left to warn future generations. Lin Shu guessed.

"It's a pity, I don't know!" Jessie said with some regret.

Ao Yun smiled proudly: "What's so difficult about this, give me a little time, and I will be able to decipher it soon." ”

Only then did everyone remember that Ao Yun was originally the spirit of a data system, and he should be very good at analyzing these data.

So, everyone dispersed, searching for what they thought was interesting, leaving Ao Yun alone standing in front of the metal wall and analyzing the words, the reason why Ao Yun was so confident was because the number of these words was large enough that he should be able to draw conclusions quickly.

In Ao Yun's memory, he wrote down a large number of words, and when there were enough types of words, he could almost quickly apply the unknown words to the inherent patterns, after all, the way of thinking of higher beings had quite a lot in common.

Sure enough, a little more than half an hour, Ao Yun smiled: "It's interpreted, everyone!"

Before Ao Yun's words fell, the people who were originally distributed everywhere gathered around, all of them stretched out their ears and waited to hear the story.

"This is a pinyin language script, so many words are contextually linked, and some of them are guesses when interpreted. ”

Lin Shu nodded: "Well, I understand, let's start." ”

"This is a text that records the reasons for the decline of this civilization and their final whereabouts, Lin Shu's guess is correct, the death of this planet is the result of the overexploitation of the dragon vein branch. ”

"Overexploited?!"

"Well, I'm just guessing, this word should refer to a certain amount of power, an endless stream of power that gushes out of the ground, according to the statement that these forces can be transformed into multi-system magic energy, this should be the power of the dragon vein, yes, but Lin Shu, I don't understand, what does excessive consumption mean, didn't you say that the power of the dragon vein flows through the universe endlessly, how can it be overdeveloped?"

"It will be overexploited, the transformation of the power of the dragon vein is carried out through the core of the planet and the inner layer of the planet, if the power of the dragon vein is overused, it will accelerate the destruction of the stability of the inner layer of the planet and even destroy the core of the planet. ”

"I see, it seems that they haven't figured out why overuse will cause the death of the planet!"

Lin Shu smiled bitterly: "I'm just guessing, the planet in front of me is the first planet to confirm this guess, although the price is a little bigger." ”

Everyone nodded, it turned out that there must be a limit to the power of developing the dragon vein, and the living example is the death star in front of them. (To be continued......)
