The entire building has a diameter of 200 meters and a height of more than 100 meters. The surface is quite smooth, without any gaps, and there is no pattern, pattern or text on it. It is a perfect arc shape, dull like an inverted ball.

Before the end of the world, buildings of this scale were inconspicuous at all. They were larger and more magnificent than them. But now, here, this island where mutant beasts raged and humans were extinct. This building standing alone in the valley hidden under the jungle seems particularly abrupt, with a strange and bizarre feeling in the night.

Luo Yuan looked quietly for a while, adjusted his breathing, and was about to continue approaching, but he had only advanced several hundred meters.

He suddenly felt something strange, it was too quiet here.

It was so quiet that even the common insects in the jungle were rarely heard, and what could be heard by the ears, if you carefully distinguish them, they were all sounds from farther away. He suddenly realized that since he approached this building, he had crawled all the way and did not find a mutant creature.

He couldn't help but feel horrified and quickly looked around. Wherever he saw, except for the plants that were still normal, there were no traces of other creatures.

"This is definitely not a normal phenomenon, is it poison gas or other means?"

Luo Yuan's heart couldn't help but thump and did not dare to be careless. He quickly sank into his body with his will. He checked it carefully, but found nothing unusual. Then, he carefully checked the ground, and there was no corpse here.

He breathed a sigh of relief, gritted his teeth, and continued to move forward.

This investigation of extraterrestrial civilizations is of great importance. If he is scared, he will return immediately. Even if no one punishes him, he will not be able to pass this level in his heart.

He slowly moved towards the building, wearing black clothes, the best disguise in the night. He was like a slowly squirming shadow, without any dangers along the way. Half an hour later, he successfully arrived at the building more than 1,000 meters away.

He stopped and did not choose to get close for the time being.

This distance, even in the darkness, was already dusty in his eyes, and it was extremely clear. The smooth surface seemed to be slightly shining under the night, and there was no configuration of doors and windows on the surface. He looked around the building, but the result was still the same, and it looked integrated.

The entire building seems to be sealed, without any regular entrances and exits.

However, Luo Yuan had long expected that extraterrestrial civilizations are not life on Earth after all, and their planets are different, and the atmospheric pressure and component content they adapt to are also different. For the life on Earth that can breathe freely, the air that can be killed by aliens may be fatal. There is obviously an independent air damage system inside this building.

The night was as quiet as water. Luo Yuan pulled open the dead leaves under him, sinking his body into it, and gently exhaled a breath of turbid air. There was a strange excitement on his face.

Although his body is still thousands of meters away from the building, he is not only waiting for him.

The wonderful use of foresight allows him to use various illusory actions conceived in his mind to test the reactions of extraterrestrial civilizations.

The first scene is that he stood up and slowly approached the building with a swagger. After two seconds, he still did not receive effective feedback and failed.

In the second picture, he began to run towards the building, and flew straight and quickly towards the building at a speed of nearly 300 meters per second. However, after running less than 0:1, a small hole suddenly flashed on the surface of the building, and a high-energy ray hit Luo Yuan's forehead in an instant, and his eyes went black.

The building's automatic defense ability seems to be particularly sensitive to high-speed objects. It can detect targets before zero or so, and automatically attack. His face looked a little ugly and he pondered slightly in his heart.

After a long time, he tried again.

This time the picture was not running straight, but moving forward irregularly in an S-shaped shape. The attack appeared again after zero point and one second. The first high-energy ray fell, followed by the second high-energy ray and it fell dark in front of him again.

Luo Yuan tried several times again. Except for the first one that could sometimes avoid it, the second one was definitely not spared. Each time it ended with a hit on the forehead and a black screen.

Luo Yuan's face was as solemn as water, and his heart was beating violently. Extraterrestrial civilizations must have terrible intelligent fast locking capabilities and powerful data analysis and computing capabilities. In this case, no matter how irregular or irregular he progressed, he just couldn't surpass its data analysis and computing capabilities, the movement trend was completely predictable.

This is simply terrible. Even an evolver with his strength is waiting to die under such an attack. No matter how he avoids it, no matter how strong he is, he is agile or fast, he will only have the end of death.

If I had no ability to predict and break in rashly, I would have ended up like in the picture.

After the violent heartbeat calmed down slightly, Luo Yuan continued to test again. This time he conducted a long-range attack test and threw short spears and stones from a thousand meters away.

Each short spear or stone roared in his hand at a terrible speed of nearly three times the speed of sound. Its agility of up to sixteen points made the attack frequency extremely fast. It seemed to turn into a Thousand-Handed Guanyin, and countless arms were waving in the air. The attack was like rain for a while, but it flew dozens of meters away and was transformed into the air by more high-energy rays. The last ray instantly melted his head, and it was black again.

That night, he kept using premonition to test, and even finally he took the courage to approach, but before two hundred meters, he retreated, because moving forward was a high alert area for building automatic defense. No matter how slow he was and how harmless he was, he could not escape the attack. He had no blind spots in attack and loopholes that were easy to exploit.

The result of the predicted temptation made him desperate. The best ending was that he hid in a huge rock and buried his body in the ground. After the high-energy ray cannon failed to make any contribution for a long time, a ball finally flew out from the top of the building.

This time, he did not see his death because two seconds had passed, but I think the ending was probably no different from the previous one.

Seeing that the sky was getting darker, Luo Yuan sighed and carefully left the place slowly. After half an hour, he returned to the hole before and quickly entered.

His body was leaning softly against the rock wall, his face full of depressed and haggard. He seemed to have been hiding in the distance, motionless. However, the invisible confrontation in the foreseeable image was no less than the battle between life and death, especially the huge gap in strength displayed behind the despairing endings, which made him feel as if he was silenced and could not see any hope.

He couldn't even break through the first outer defense.

He leaned against the rock wall, frowned, and pondered in his heart, but how could he think of a solution in a short time?

This building is like a hedgehog full of spikes, and it is impossible to get close to it. Now he can only hope that aliens or intelligent robots inside will not stay inside.

The mission he came out this time was: to investigate information about extraterrestrial civilizations, and to obtain scientific and technological items of extraterrestrial civilizations as much as possible, while hiding himself. If there is danger of exposure, he will give up.

The task requirements for the reconstruction area are relatively broad and very cautious. Everything is based on the premise of not being exposed. There are no mandatory requirements. In fact, after testing this step, no evolutionary will come here, and it will be almost the limit to obtaining this information.

However, Luo Yuan was really unwilling to return without success, and he also didn't want to see that under the strong crushing of extraterrestrial civilizations, the reconstruction area had no power to fight back and was wiped out.

At this time, the forest suddenly became turbulent, and countless creatures seemed to be running around madly.

"What happened." He felt a stern in his heart, quietly drilled out of the cave, lowered his body and looked around carefully.

At this time, he keenly discovered that there was a very faint vibration in the air, which seemed to be there or not, and the vibration frequency was extremely low, and the fluctuations were almost visible to the naked eye. Under this fluctuation, his internal organs seemed to have a tendency to tremble.

He looked at the mutant creatures that were stimulated by this fluctuation not far away, and looked in the direction where the fluctuation came from. It was from the valley. He suddenly realized it in his heart, and then felt a little scared in his heart.

"No wonder there are almost no mutant creatures in the valley near the building. It turns out that they were driven out by infrasound waves. Fortunately, this place is located behind the peak and is absorbed by the mountain and air. When it comes here, the infrasound waves are already extremely weak."

"Infrasound can resonate with biological organs. At the very least, the organs are damaged and dizzy and nausea. At the worst, the organs are broken and death will be caused. It is extremely dangerous. If he had not had time to evacuate before, he might even fall into it."

"Yes, fluctuations, resonance!" At this moment, he suddenly became blessed to his heart and a trace of inspiration arose in his heart.

A grim smile flashed across his face. Since the buildings of foreign civilizations are like hedgehogs and make people unable to get down, they will knock them open with violence.

Perhaps triggering an earthquake can solve this problem perfectly.

Each time the earth tramples, it is a vibration, and through resonance, it causes regional earthquakes.

This was the idea he had when he was rebuilding the area, but the plates in that area were too fragile, and small earthquakes occurred from time to time. He could not estimate the consequences of resonance. In order to avoid causing a major disaster, he had never tried it.

After coming out this time, although he left the reconstruction area, there was no urgent need. This experiment was gradually thrown behind by him. If it weren't for the discovery of the infrasonic waves, he would have been inspiring for a while.

However, before this, he had to choose a safe place without disturbance. It was too close to the valley. Before the real earthquake, the earth was trampled on and off the ground. As long as he was not blind, it was difficult to ensure that he would not be detected outside the ground.

But it is also not enough to be too far away. Not only is it difficult to trigger resonance in this area, but it is not only effective, but it is also easy to alarm the enemy and arouse suspicion of extraterrestrial civilizations.

This is undoubtedly a dilemma!

Luo Yuan's eyes were turned on and he quickly got an idea.

He untied his straps and entered four-dimensional vision. His method was to use the independent space formed by curvature flight and go directly underground.

His face was heavy. This method was quite dangerous. Even if he had predicted that he could detect the danger of the earthquake two seconds in advance. If it was not good, he might die and be buried underground forever. However, now, there is no other better method in a short period of time.

The curvature flight started instantly, and the space slowly twisted. After five minutes, the space bubble gradually formed.

The space bubble he controlled slowly sank into the ground. The sight here is useless. Only perception can make some vague judgments, and the range has been greatly reduced. The distance of the 100-meter exploration was now less than 34 meters, but it is enough.

In order to create a greater effect, he slowly moved towards the valley in his memory.

He stopped and stopped moving forward until the periphery of the valley, about seven or eight kilometers away from the extraterrestrial civilizations.

Then the will of the will erase the space bubble, and the space spreads rapidly, and a circular space of two meters in square radius was formed inside the mountain.

This location is located in a low ground, with a drop of seven or eight meters from the nearby area, and about six meters away from the ground above the head. If the humus layer close to two meters is removed, the rock layer is as thick as four meters.

This distance is the safety threshold he used violent breakthrough when an earthquake or collapsed. Once something went wrong, he would immediately break out and escape perfectly.

It is also the longest distance that can escape safely within two seconds in the predicted test results.

This is his last insurance!
