Properly arranging the immediate matters, Chen Yiqi said with emotion: "Compared to other old settlements, is our Zifeng Base City really so far behind, they have actually mastered the artificial method to create such a large-scale beast tide...... And now, we are even trying our best to cope with the natural tide of beasts that occur every year. ”

The adjutant explained:

"Although there is a human element to these three waves of animal tides, we can draw a conclusion based on some analysis of the traces of the site, as well as information collected from previous years and before this animal wave took shape to this extent. These three waves of beast tides were not created by them out of thin air, but were caused by the situation. ”

"Caused by the situation?" Chen Yiqi looked at him curiously.

"Yes. The adjutant nodded affirmatively and said:

"If you really want to say it, the beast tide that our base city is suffering from from all over the wilderness at any time and place, and the beast tide has never stopped. It's just that the scale of the huge part is less than a thousand, or even less than a hundred, such a scale, not to mention the 'tide', just an insignificant small wave impact, and the nearby forces do not need to use any external force at all, it can be completely eliminated, the movement cannot be spread, there is no loss, but it is like a resource that is actively sent to the door, in the ordinary statistics, we do not classify these as the 'beast tide'.

According to the statistics over the years, during this time period, these three areas outside the base city are the areas with the most dense small-scale beast attacks, because they are the connecting belt of several areas in the wilderness, and the transportation hub in the wilderness, and several times even formed a beast tide with a scale of more than 10,000 heads.

And this time, according to the trajectory of those residual preparations we have collected, we can roughly determine the range of areas where they are used, and a comparison shows that the overlap of these areas is extremely high, and with the different types of residual preparations in each area, we can draw a clear conclusion that those enemies in the shadows are to gather the beasts that are highly dense in these areas, concentrate their forces together, and detonate them at one time. ”

Chen Yiqi nodded thoughtfully, he understood the adjutant's words, but he did not feel relieved.

Instead, he sighed: "There is still a gap, at the technical level, those preparations that we have not been able to identify, each of them is a gap, and their combined effect, I think everyone has seen it, it is really ...... Remarkable!"

"Any base city, as long as it has mastered this technology, has completely changed from 'being troubled by the beast tide' to 'enjoying the benefits of the beast tide'.

We don't have to worry about having a beast tide that is so large that it exceeds a certain threshold of bearing, and we don't have to spend a lot of money to prepare for it, but we will turn the tide when a huge beast tide comes.

Because we can use these preparations to induce and differentiate a certain area before it is possible to cause a very large animal tide.

They will make us feel embarrassed when they are pressed all at once, but if we use the tactics of adding oil to send them little by little, then none of them will refuse, this is purely to send us food. The tide of wild beasts will completely turn into a kind of abundant resources. ”

(change first, then change)

Chapter Zero: This is immortality

In the depths of the cave, there is darkness and silence.

"Xiao Wang!"

A loud cry echoed through the cave.

Wang Dan, who was hiding behind a stalactite to watch the latest chapter, reluctantly put his mobile phone in his chest shirt pocket, turned on the strong light flashlight, and walked briskly to the place where the sound came from.

The cave is very large, and in addition to the stalactites of large and small, high and low parts, it is the silent flow of clear and cold stagnant water in the layers of ditches like miniature terraces formed by the solidification of minerals over time.

There were no roads in such a place, but there were people who came and went, or barely managed to find a bend to walk and settle down with the help of the high ground outcropping or boulders in the water.

After a few bends and bumps, a young man squatted on the ground and used a marker pen to write the number number, date, temperature and humidity on the sealable plastic bags.

"Senior Brother Ruan. Wang Dan shouted.

Senior Brother Ruan glanced up at him, then took the plastic bucket in his hand and took out a stack of sealed plastic bags inside, and a piece of glass was placed in each sealed plastic bag.

After a cursory inspection, he put it aside, put the empty bag with the number and other information just written and a new box of glass pieces into the bucket, and said, "I exchanged these sets of numbered samples." ”

"Okay. Wang Dan nodded, turned around and left.

When he took a few steps, Senior Brother Ruan's voice came from behind him, "You all know where it is, right?"

"I know. Wang Dan replied. He'd been here many times, and though it was dark except for the flashlight, he wouldn't forget it all.

He did the work step by step, a few specially selected, with red paint in a prominent position sprayed with a number number of stalactites on a glass sample, dripping water dripping in the center of the sample, in the accumulation of time under the glass surface will form a thin layer of crystals, Wang Dan replaced it with a clean glass sample, gently wiped the water on the surface of the surface, put it into the corresponding numbered plastic bag and sealed, gently placed in the bucket, and then went to the next place.

He is a senior student in geology, and the selected thesis supervisor is a professor who studies paleoclimate, and after meeting him, he was thrown to the "disciple of Yanchuan" in the management of senior brother Ruan, a graduate student, in addition to occasionally helping to sort out some very simple information, the main job is to regularly come to this extremely remote karst cave to take samples, the purpose is to take samples from the layer of crystals on the surface of the glass sample, from its size, shape, quantity, mineral composition and other information, combined with the current temperature, humidity in the air, rainfall in the area, Through long-term and continuous observation, a clear causal relationship is obtained, and stone stalactites are "grown" over hundreds of millions of years, and the crystal information of each era is completely preserved, so that the temperature, humidity, rainfall, and even air composition at the time of their formation can be reversed. Taken together, all of them are in the basket of "paleoclimate", which is an important basis for the study of ancient earth, paleontology and even ancient civilization.

It sounds fun, but it's boring to do.

"There's only one last place left. ”

The location is just opposite his current location, if you follow the original road, you have to make a big bend, the last time Wang Dan was quite familiar with this cave, so he directly copied the shortcut, but just to jump down a hurdle, there is a stone ridge to divide the water on both sides into different heights, but it is a natural path to the opposite side. This time is no exception, he took a flashlight to find a good foothold, jumped down with a bucket, about a meter of the hurdle said high or not low or not, half squatted down and unloaded the force, the person has stood firmly.

Though a man is steady, his heart is suddenly raised.

"Oops!" he exclaimed.

With his series of jumps and squats, the phone in his shirt pocket has long since come out and is moving away from him quickly, and soon, he will fall on the hard rocks or fall into the water - no good end anyway!

And now he is holding a plastic bucket in one hand, which contains precious and fragile samples, and a flashlight in the other, without which it is difficult to move an inch in this dark cave, and he does not dare to throw it, and the time to save the mobile phone is fleeting, he can't think about it at all, between the lightning and flint, he instinctively took action.

His eyes caught the phone moving away quickly in the air, and he hurriedly approached in a few small steps, waving his left hand holding the bucket in unison. The eyes are fast, the hands and eyes are coordinated, and the falling mobile phone just landed on the inner wall of the plastic bucket at a 45-degree angle. When the phone continued to fall against the wall of the barrel and gently fell to the bottom of the barrel, his hanging heart finally landed.

"Oops!"

He screamed strangely, and all his attention was on the hand-eye coordination and the safety of the mobile phone, but he didn't realize that his body was already out of balance, and he stepped forward to step on the air, completely out of control, his hands were dancing wildly, his feet were in the air, and his head was in close contact with a small stalactite like a bamboo shoot, like an egg on a rock.

Only one thought crossed his mind.

"I hope it won't scare Senior Brother Ruan. ”

When he woke up again, he found that he had changed.

Wang Dan turned into a stone egg, a fossilized egg buried in a rock formation with a huge stalactite pillar pressed on top of his head.

Not hungry, not thirsty, not old, not dead, not moving.

Since regaining the sense of time, the stalactites on their heads have grown more than 100 centimeters taller again, and it takes thousands of years for each centimeter to increase!

Every time he thought about it, he felt incredible.

"Immortality as soon as you pass through, are you not satisfied?" he sometimes comforted himself.

"I'm not crazy like this, I'm really homely. He occasionally laughs at himself.

"I'm not a human anymore, am I?" he felt crazy when he first thought about it, but then he gradually got used to it, and even became extremely calm: "I'm not human anymore." ”

Even so, he was not willing to be imprisoned in a fossil egg forever. At first, his consciousness could barely get out of the shell of the fossilized egg, and he felt sluggish when he took a step out. He worked hard, he struggled, his mind was free of distractions, his spirit was rapidly consumed, he was so tired that he fell into a deep sleep, and when he woke up, he worked hard and struggled again, his "vision" expanded little by little, and he went deep into the rock overhead, "saw" the stalactite pillar on the top, and then "saw" a stalactite forest around him.

A closed karst cave space, nearly fifty meters at its highest point, approximately circular, with a diameter of two hundred meters. Darkness, silence, only the slight ticking of seepage water rhythmically tapping on the stone forest, and the rock formations that covered the space up and down did not know how deep.

Waking up again, Wang Dan "looked" at the time.

"113.4 centimeters, a little higher than before going to bed, but it's only a millimeter, about 1,800 years, and the time of each sleep is getting shorter and shorter, which is also a good thing. ”

He first made a routine round, and there was nothing unusual as expected.

"Alright, go to work. ”

He restrained his scattered thoughts and concentrated them in one direction, and the "field of vision" that originally covered the entire space quickly narrowed.

The cave space is high and low in the center, and the seepage water converges into a deep pool in the center. The mirror-like waterhole seems to have a wind blowing, ripples constantly, and under the impetus of an invisible force, an arm-thick waterline crosses the entire pool surface, bringing a stream of water away from the pool.

Like a long snake without a tail poking its head out of the pool, along a slightly sloped, smooth and straight, countless times back and forth "snake road" forward, the initial speed is quite slow, but it continues to accelerate, after a while, it reaches the end of space, as if it is about to hit the mountain rock, but not "broken bones", but in a small tunnel faster and faster.

His mind can not only be transformed into a "super vision" that covers no blind spots, but when it is extremely condensed, it can also interfere with reality with its mental power. This force is too small to directly damage rocks that are harder than steel.

"278 meters per second, 7305 meters. A set of data came to his mind.

The former is the maximum speed of the waterline, and it is also the limit of what his current mental mind can support. This is also the result of the growth of this sleep, which has increased by nearly ten meters per second compared to the last time.

The latter is the distance he travels through the tunnel at such a high speed at the head of the waterline.

Because the speed difference between the front and rear is too large, the further you run, the thinner the waterline, and when it stabilizes at the highest speed, it is like a sharp arrow made of water.

Shot hundreds of meters again, and finally hit the rock at the end of the tunnel, and then turned around 180 degrees, carrying the "wreckage" of some micro rock mass, clinging to the waterline and returning to the waterhole, forming a never-ending loop.

The tunnel continues little by little, inch by inch.

One inch two inches, one meter two meters.

When he was completely exhausted and fell into a deep sleep again, the tunnel extended forward more than a hundred meters again. He slept peacefully, and although he didn't know when he would be able to get his head out, he was not in a hurry at all.

After I don't know how long it was, I "saw" the whole picture of the stalactite pillar above my head step by step through the rock formation outside the eggshell, and regained the perception of time; and then slowly expanded, exploring the entire cave space; my mental power was too weak to directly achieve results, so I thought of turning water into a soldier's indirect method......

This is all his harvest, and he has been harvesting all the time, so he is naturally not in a hurry.

A group of mountains, lush and vast, like a group of skyscraper beasts towering their backs and prostrate on the vast land.

Somewhere, in a hidden basin, there is a natural stone cave only a few meters deep, wide and high, and a few small creatures with gray-white hair, like rabbits and rats, hold nuts the size of a baby's fist and gather on one side to eat.

Suddenly, first the first, then all of them, stopped chewing and eating, their ears erected high, and their ears swayed rhythmically along the villi.
