Yu Fei was very fast and kept changing cover, allowing him to approach the opponent quietly. Soon even the old professor didn't know where Yu Fei had arrived.

When Yu Fei appeared again, he was suddenly standing behind the man in protective clothing.

Yu Fei looked at the man in front of him who had his back to the outer edge of the basin and facing the lake. He was standing behind him. He hadn't noticed yet, but he didn't know how to act.

"Hi, buddy!"

After Yu Fei thought for a while, he shouted.

The man shivered in fright and turned his head sharply, because the face of the protective suit was covered with a transparent cover. I don't know what kind of material it was made of, but at least it could transmit light.

Yu Fei took one look at the other person's appearance, then turned to look at the old professor in the distance.

Because this man doesn't look like a bad guy, he looks like an old man doing research just like the old professor.

"What are you doing standing here?"

Yu Fei asked speechlessly. Through the mask, he could see that the other party was quite old. He was not ready to do anything. He suspected that if he could not control his strength, he might hurt the other party.

"I took a helicopter last night and came from the other side. By the way, why don't I recognize you?"

After the other party stared at Yu Fei for a while, he asked even more doubtfully.

"Do you know the old man on the hillside?"

Yu Fei felt that everyone might have misunderstood, so he had to lower his tone and asked.

"I know him, tell him to come down!"

The old man in front of him didn't want to talk to Yu Fei anymore. He probably thought that he was the student of the old man on the hillside, so he spoke directly in a commanding tone.

Yu Fei picked up the walkie-talkie from his waist. Everyone was given one of these yesterday, but they didn't use it at all. Now that it's useful, it saves him the trouble of running errands.

"The old man below said he knows you and asked you to come down."

Yu Fei turned on the intercom and said directly.

As soon as Yu Fei opened his mouth, the people on the hillside all tuned to the public channel, their walkie-talkies all rang, and they were woken up.

Then I saw those people starting to walk down from a distance. They couldn't carry the box that Yu Fei had brought last night, so they stayed where they were.

Yu Fei was speechless and wanted to be lazy, so he quickly walked up the hillside. When he came down with the box on his shoulders, all those people came down to the edge of the lake, which showed the difference in physical strength between these people and him.

.

Then he saw two old men chatting alone. Of course Yu Fei wanted to eavesdrop this time, because he would definitely be very interested in the content of their conversation.

Yu Fei found a seat and pretended to smoke, but in fact he let go of his hearing. He could clearly hear all the conversation between the two old men.

Yu Fei faced the direction of the lake, so no one saw the weird smile on his lips.

Because the two old men had already determined that the source of radiation was not the jade mine, but underneath the middle of the lake.

That means that first of all, there will be no problems in the mining of jade mines, and this financial path has not been cut off. Secondly, the reason for the rapid evolution that I am looking for is probably the bulge under the lake, and that bulge should be

source of radiation.

The two old men chatted for a while, then came back and started to organize everyone. They took out all the instruments and started arranging them around the lake. It was roughly a circle that surrounded the entire lake.

Yu Fei pretended not to know anything, started to carry things, and started walking along the lake. After walking for a while, the old man's voice came from the intercom, and he put it down.

something, and then move on.

Soon all the instruments were placed, and the two old men sat together in front of a few things that looked like control equipment, writing and drawing while discussing.

Everyone ate the compressed dry food they brought. Yu Fei ate just to satisfy his appetite. He didn't have to eat it at all, so he put his own portion back and eavesdropped on the conversation between the two old men.

Sure enough, the final conclusion of the two old men was that the source of radiation was under the water and very deep.

After they finished discussing, they made a call and asked for divers and diving equipment to be sent.

At noon, Yu Fei saw the helicopter circling the top of the mountain, and seven or eight people were sent down. Those who came to the lake, and according to the requirements of the two old men, some equipment was launched into the water.

But Yu Fei knew that these people would return in vain, because the depth of the center of the lake could not be penetrated with such crude equipment.

Sure enough, it didn't take long for those people to come up. Just as Yu Fei expected, they couldn't dive to the bottom unless they got a submarine.

But how could a submarine be sent here? This is an impossible solution.

When the two old men were about to send these divers away, a diver suddenly came up with an idea and told them that they could drain the water with a water pump, which would be much easier.

The two old men immediately became energetic and immediately called again, asking for a complete set of water pumping equipment to be delivered.

Yu Fei waited boredly again, and the divers were picked up. In the evening, the helicopter came again, and still delivered five or six people and equipment.

Yu Fei couldn't help complaining that he had to take out all this equipment a long time ago, so he would have to follow these people and walk all night yesterday.

After the water pump and generator were quickly set up, the pipes were also connected. To pump the water out of the basin, the most powerful water pump could not do it, so a pit was dug in the middle of the hillside and a water pump was installed as a relay point.

.

After all the equipment was ready, water pumping began, and the water pumps and generators roared together.

However, draining the lake was really not a small project. Another set of equipment was delivered in the middle of the night and the work started after installing it.

But this time I brought you some things that taste pretty good, including braised pork, canned luncheon meat, noodles and rice, etc.

With nothing to do, and fearing that he would be considered useless and asked to go back, Yu Fei took the initiative to serve as the chef and cook for everyone.

Everyone was very satisfied with the meal, Yu Fei's value was reflected, and of course no one asked him to leave.

The several water pumps that were delivered were quite effective. In one day and one night, the water surface dropped by seven or eight meters, and it was close to the center of the lake. The funnel-like position was about to emerge from the water.

Yu Fei knew that it was almost done. It would take at least a day for the water to be pumped out.

It's like a big bowl, wide at the top and narrow at the bottom. If the top is one centimeter deep, the water at the bottom needs to be filled with several centimeters.

Yu Fei glanced at the water, turned around and opened several cans. After pouring them into the pot, he started to make soup. Various seasonings were sprinkled into the pot, and the aroma suddenly spread in all directions.

"Professor, professor! Here we are! Here we are at the funnel!"

At this time, in the center of the lake, the person who had been moving the water pump forward shouted loudly.

Yu Fei took a look, lowered his head and continued to concentrate on making soup. The man must have discovered that the water pump had fallen, and knew that most of their projects were completed, so he was very happy.

Although the two old men didn't move around much, they knew the situation here best and were talking calmly.

The machine told the other party to continue pumping water, and then continued their research.

Another day passed. Yu Fei made breakfast, a pot of stewed soup, but it tasted great. After it was cooked, he said hello, then he took a sea bowl and sat down to eat.

As more than a hundred meters of ropes and pipes were lowered, the water below was almost exhausted and would bottom out before noon.

Yu Fei prepared to have a full meal and then waited for the moment to witness the miracle.

But it is very dangerous for people working there now. To be honest, the radiation must be very serious.

The two old men and the scientific researchers they brought had moved back without leaving any trace.

Those few people working in the middle of Caihu are all people sent from behind and are not considered our own.

Yu Fei didn't care. Although he could feel the damage caused by the radiation energy, the spiritual energy could offset this damage, as long as he didn't get too close.

After eating and drinking, Yu Fei stretched out his muscles. He knew that not only those who were controlling the water pump were not one of his own, but Yu Fei himself was not one of his own, and he might have to take risks soon.

Sure enough, when it was almost noon, the people over there shouted that it was bottoming out and the water had been pumped out.

Then the old man asked them to wear two layers of protective clothing and go down there to take a look.

Those people were probably professionally trained. Although they knew it was dangerous, they went down without hesitation after receiving the order.

Yu Fei's expected decision to let him go down did not happen, and the two old men seemed to have forgotten about him.

He smoked a cigarette and waited for the results.

More than half an hour later those people came up, but they were all empty-handed.

After coming up, of course, they immediately reported their findings to the two old men.

The content of their report was very simple. An irregular object was found in the middle of the exposed bottom.

However, this object is very heavy, as if a whole piece of metal cannot be moved, so special equipment must be found.

Yu Fei looked at the photos they took from a distance. It was similar to the photo he had taken that day. It looked like stone, but was actually metal.

Then we waited another day for the lifting equipment to be brought in and installed on the top of the hole-shaped structure. Then a few people went down to fix the special chains and other items on the metal below.

This time the old man and their students did not retreat, and Yu Fei also watched from a distance.

Several assembled cranes began to work at the same time. Yu Fei immediately felt the changes in radiation. Now he has gradually become accustomed to the invasion of this power.

The engines of several cranes were roaring. Logically speaking, things weighing tens of thousands of kilograms could be easily pulled up, but it seemed to Yu Fei that the chains were being pulled up very slowly.

After more than an hour, Yu Fei finally saw the true appearance of the thing from a distance, like a big burnt stone.

People wearing several layers of protective clothing, with the cooperation of machines, transported the thing to the shore bit by bit.

Yu Fei frowned, is it really just pure radiation?

This thing must have flown from the sky together with the jade. Because of its own weight, it landed in the middle of the basin, creating a deep funnel-shaped pit.

But if it's just radiation energy, why hasn't something like a water monster appeared after humans discovered the existence of radiation for so many years?

A lot of doubts appeared in Yu Fei's heart. He stared at the thing and was slowly sent to the shore. As the distance got closer and closer, even with the protection of protective clothing, Yu Fei still felt invaded.
Chapter completed!
