After the crane comes up, things are much easier, and the people below don't need to climb up one by one like Yu Yifeng, just use the crane.

He first fixed the small crane, then turned on the crane and lifted the exploration team members up one by one, along with two large boxes of equipment and materials.

Half an hour later, ten members of the team stood on the platform, looking around vigilantly. The three engineers took the lead in setting up a signal base station, and then released small robots out of the box. According to the plan, they will become pathfinders.

Humans have been cautious enough to do this, so to speak, to ensure the safety of the explorers.

The hole was not large, it could only hold the position of one person at most, and there was no light, no sound, and no change......

Seems...... Dead silence!

No matter what, the right thing to go is still to go. Yu Yifeng licked his lips and said in a deep voice: "Channel 319.4, I'm Yu Yifeng, the signal base station has been built, and the exploration robot is ready!" Execute the next step! ”

"Order received, signal facility is being checked......" was the voice of the crew of the Noah.

Although there are only ten people here, there is still a whole control center standing behind them!

"Check it out, bot search begins!"

More than two dozen spider robots moved in an instant, and the two electronic eyes above their heads bloomed with bright white light, and they lined up and jumped into the hole......

The robot that is not afraid of death still works, and more than ten minutes later, the control center on the Noah informed the team members of the situation.

"The situation inside is okay, and the facilities and equipment are also seriously damaged, but overall, it is much better than outside...... For the time being, no unsafe places have been found, and it is possible to enter. ”

"Let's go!" Yu Yifeng listened, and waved his hand to the people behind him, although the uneasiness in his heart gradually rose again, but now he can't care so much.

Even if there is an internal danger, it must be faced. Besides, the robot is exploring the path ahead, and if there is danger, it will also affect them first, so as to give humans a time to react. If there is any unstoppable danger, they are here to explore, not to die......

Yu Yifeng was the first to enter through the hole, picked up the Gauss rifle, and walked at the front of the line, followed by Zhao Yao, who was resisting the bazooka, then Zhang Jun, and the rest of the people lined up one by one, and Shen Jie was responsible for the last guard.

The entrance to the dark cave is like a dark monster's mouth, waiting for the expedition members to throw themselves into the net......

But there's already a little light inside, and it's their spider robot exploring the way, which also makes everyone's hearts a little better.

After everyone entered, they all picked up their weapons and made vigilant movements, and then turned on their flashlights one by one.

The irradiation range of this model "Shenhuo II" military flashlight is 600 meters, and the lighting capacity of a single charge is more than 6 hours.

Everywhere they saw was a metal wreckage. Yu Yifeng squatted down and picked up a ring-shaped thing with a small amount of dust on it, which might be a part of a certain machine.

It looks like a factory, but the equipment inside has been damaged by the crash of the flying saucer. To be honest, everyone has a little regret in their hearts, and it would be nice if they could find something valuable here......

Under the illumination of the light, these metals are only covered with a layer of ash after millions of years, and they still have a faint luster after being wiped clean, a quality that at least human technology cannot do.

"Look for it first, and find out what is useful." Yu Yifeng commanded several engineers, while the rest continued to be in charge of guarding.

"Look at this!"

Zhao Yao was pleasantly surprised to find the remains of some combat robots, and kicked them with his feet, and some of the things on them were almost complete! He was immediately interested, and even wanted to disassemble a Gauss rifle for use, but was stopped by Yu Yifeng.

"You definitely won't need it now, put it away first and transport it back!"

The Gauss rifle in Yu Yifeng's hand was modified by scientists, and in the hands of these robots, there were no wrenches, sights or anything like that, and they couldn't be used when they were removed, so Zhao Yao could only give up when he heard it.

After about half an hour's work, everything useful was sorted out, and the harvest was so-so, and there were no particularly significant findings. The whole team had to move in again, moving cautiously.

Everyone became more cautious, following a path that the robot had explored.

Scientists have detected energy fluctuations in flying saucers, although they are plausible, and it is still unclear whether they are true or false...... This couldn't help but make Yu Yifeng frown slightly, what was the sense of danger in his heart?

At this time, the control department on the Noah sent this message: "Come here! This passage is the most well-preserved, it has been inspected inside, there is no danger, and there may be good equipment inside! ”

Yu Yifeng nodded, and led everyone into this passage, at this moment, he felt that the cold hairs all over his body stood up, he subconsciously stopped, and looked back at Calvin.

Calvin also endured his fear, looked at Yu Yifeng, and shouted loudly: "There may be danger inside!" ”

"At the turn of 100 meters in front of the left, there is a device similar to a computer!" The voices from the control department became more and more surprising, and there were even the frantic shouts of the scientists: "Just ahead!" ”

Yu Yifeng was silent for a while, but still gave an order, "Keep going!" ”

Although the robots had checked it several times, they were still cautious, standing in their respective positions, moving carefully. This corridor is indeed relatively intact, and there are not so many cracks in the ground under your feet, so it leads straight to the innermost point. Yu Yifeng's Gauss rifle was aimed at the front, while behind him Shen Jie was responsible for guarding the rear.

At this moment, some new thoughts came to his head for no reason:

Why is this passage so straight, and where is it leading? Where did all the extraterrestrial life go inside? Also, is there a connection between the Martian virus and this flying saucer, and is it brought by this flying saucer?

These are the points of constant debate among scientists, but many people still insist that the Martian virus is the original protogenus of Mars!

Otherwise, there are some higher-level microorganisms in this flying saucer, why not now? Why didn't you find anything at all?

The only explanation is that they were all killed by the Martian virus! The Martian virus is very aggressive, and the foreign microbes in the flying saucer are not their opponents, just like the earthlings.

Well, there is some truth to this statement, aliens are technologically advanced and are not afraid of Martian viruses. However, alien microbes may not be the case......

What about longevity viruses? Scientists speculate that they may be the only thing left of an extraterrestrial civilization! This also explains why it is so complex and the genetic sequence is difficult to decipher......

Wait, why are you thinking about these questions at this time?

Yu Yifeng was suddenly startled, he was actually distracted at this time!

A superhuman was distracted at this time! Suddenly, a chill came out of his heart, and he hurriedly shouted: "Stop! Stop it! ”
