Leng fan agreed with the performance of these two powers on the hostile ships, because they would not bow their heads and beg for mercy when facing death. So he immediately took out two pills, gave them one for each, and said, "I only have two pills here. If you take one for each, you won't be charged."

The two powers really did not expect Leng fan to be so generous. One of them asked, "are you from Kunlun sect?"

Leng fan took out a few pills today, which are really valuable. Among the major forces in the world, only Kunlun sect can give pills to others at will. So these two powers guess that Leng fan's identity may be a disciple of Kunlun sect.

Leng fan replied, "there are some origins, but they are not in Kunlun sect at present."

Leng fan's answer was very vague, but in their eyes, he was a member of Kunlun sect.

Professor Tai came slowly, still holding the ancient book in his hand. He was really afraid that the book would be robbed, and he was always ready to advance and retreat with the book.

President Cao finally said: "we all have a good rest. In the next few days, our warships will cruise around to protect us until we finish the postgraduate entrance examination."

So for the next two days, they were very leisurely, except for Professor Tai, who was a "madman" in ancient books. Two days later, the newly developed deep-water submarine was successfully delivered.

Professor Tai couldn't wait to say to President Cao: "President Cao, let's start now!"

"Professor Tai, you are too anxious. The new deep-water submarine has not yet completed all the tests, and now it will dive directly into the seabed, which is also a great risk. Therefore, before we formally explore, we must make adjustments for a certain period of time. "

Professor Tai also knows that, but he is really worried. He has found the books of the previous generation before he has reached the deepest level. Next, he is very confident to discover a bigger secret, which will be a historical change for the whole mankind.

"I'll let them debug as soon as possible and try to get into the water for the first time tomorrow," Cao said

Leng Fan said at this time: "this time I will enter the water together."

President Cao hesitated for a moment, but nodded and agreed: "OK, there must be a quota for you."

That night, long Haotian said to lengfan, "I can't sit down. It's not interesting to sneak in with them. I'll go down first."

Long Haotian wants to sink alone like the bottom of the sea. Leng fan thinks it's OK for him to do this. After all, other people don't interfere in what they want to do.

"Then you go! If you do find something, you can't take all the benefits. " Leng fan returns.

Long Haotian laughed and said, "don't worry, I really found something. I will never lose you."

The next day, Premier Cao prepared all the preparations, and today's world is particularly sunny, and there is only a little prestige on the sea, so today is very suitable for all kinds of scientific research activities.

Leng fan and Professor Tai went into the deep-water submarine together. The space in the submarine is not big, but it is bigger than the previous one, which can accommodate seven or eight people.

This time, Dean Cao also entered, of course, there are two powers, the rest is the submarine operator.

"Attention, everyone. We start to dive. We may feel uncomfortable, but if it's not serious, it's normal." The leading operator warned. The name of the operator is Li Shan. Although he is only a driver, his rank is vice president.

Leng fan is sitting by a small window. At this time, he can see all kinds of fish in the Chu sea, but then he sinks, and the visibility becomes more and more blurred. Finally, he can't see anything. However, at this time, the submarine turned on the light outside, and everything around the submarine could be seen clearly. But it's impossible to see from a distance.

An hour later, the instruments inside the submarine showed that the depth of their penetration was 12000 meters.

"Pa pa..." applause suddenly broke out in the submarine. Everyone was very happy except Leng fan.

If Leng fan doesn't know, the depth of human knowledge has exceeded the limit of human records. Once this data is spread, it will be the front page of major news. This is the evidence that human beings have once again defeated nature.

As a captain, Li Shan suggested to President Cao at this time: "President Cao, we can go up now. It may be dangerous to go down again."

If it's just to explore the depth of the submarine, President Cao will certainly agree, but the purpose of their trip is not to break the record, but to enter an unknown world.

"Captain Li, if everything goes well, we will continue to sink. Of course, I'm just suggesting that it's up to you. " Premier Cao replied.

After hearing this, Li Shan hesitated and said, "Premier Cao, I will cooperate with you. But if there's a warning on the instrument, I have to go up. We can't risk the life of that boat. "

President Cao said, "thank you. Continue to dive."

Leng fan is sitting by the window. Now he can't see anything outside, so he unfolds his divine consciousness to see what kind of world this dark underwater world is.

The deep-water submarine continued to dive. When the depth reached 15000 meters, Li Shan stopped diving and said to President Cao, "president, the radar shows that there are very complicated stones around us. It's very dangerous to continue to dive. Even if the diving is successful, it's also very dangerous to float up again."

"That helps us turn on all the searchlights. I want to see the surrounding environment," Cao said

Li Shan immediately turned on all the power and saw that everything could be seen clearly within 100 meters of the submarine.

"Wow..." Li Shan suddenly exclaimed in surprise, because around their submarine, there are floating stones in the water. These stones are very hard. At such a depth, the stones are usually pressed into powder by water pressure, but they are OK, just can't continue to sink.

"Dean Cao, look at these things. They are not stones, they are incomplete buildings." Professor Tai said to Leng fan.

Looking at the nearest stone, President Cao observed it carefully and said, "yes, I guess they were buildings on land before, but later they sank to the bottom of the sea for some reason."

Professor Tai asked: "Dean Cao, are these products of the last generation of human beings?"

Premier Cao replied, "I can't make it clear. I have to take a piece back." Then he said to Li Shan, "Captain Li, can you take one back?"

Li Shan looked around, worried: "the stone is too big, if the weight of our floating is too big, maybe even we can't float."

Leng Fan said at this time: "there is a small piece in front of you, you can take it up."

"How do you know?" Li Shan looked forward, but did not find the small piece in lengfan's mouth.

Leng Fan said: "believe me, there must be some in front. You move the submarine forward."

Li Shan shook his head and said, "no, we are surrounded by such blocks. It's very dangerous to move around. Once we float up, we don't know if there will be any danger on our heads."

Leng fan didn't know what happened, but Dean Cao then said to Li Shan, "Captain Li, you can have a try. I believe this little friend."

"Dean Cao, it's really risky." Li Shan still hesitated.

President Cao said, "Captain Li, you should believe in our major. People here have their own skills and will not make fun of their own lives."

After Cao's efforts to persuade, Li Shan, the conservative captain, finally agreed. The submarine began to move forward, but the speed was very slow, and the surrounding objects were too large. Once it hit, all the people in their boat had to be explained here.

One hundred meters away, they spent a whole hour. Leng fan almost fell asleep. What's the difference between this and tortoise climbing? Now he began to admire long Haotian. He didn't know what position he had reached and didn't come back to talk about it.

"It's true" Li Shan found a half man high object in front of him, and then he opened the outer arm of the submarine, which is a special machine to grasp the underwater objects.

"Doo, Doo, Doo..." suddenly, an alarm sounded in the submarine, which was a bad sound.

Premier Cao asked, "what happened? Is the submarine out of order? "

Li Shan replied: "no, it's the radar that has found a fast-moving thing. It's wandering around us. It's moving very fast. It must be an unknown creature on the bottom of the sea."

Li Shan's reply was calm, but I could feel that he was already nervous.

President Cao frowned and said, "I know a little about the habits of sea creatures. We don't take the initiative to provoke him. He usually doesn't attack unknown creatures. For example, we are also unknown to him. Otherwise, he would not just wander around outside without close observation. "

"Captain Li, turn off all the lights and keep the submarine silent. This will tell the creature that we have no malice against him." Premier Cao suggested.

Lishan immediately turned off all the power supply, and now it is just in a floating state. Because the power was off, they were all in the dark, and the boat was getting colder and colder. After all, the distance between the bottom of the sea was 15000 meters.

Li Shan said: "we can only persist for five minutes. After five minutes, we must start the power supply, otherwise it will be difficult for the power supply to start again."

President Cao said: "it will restart in four minutes. Whether we can let the creature leave depends on our own life."

Although they can't see clearly, Leng fan can see clearly. It's a big shark that moves very fast. After they turned off all the power, the shark did start to move outside, not to this side.

Four minutes later, Li Shan turned on the power again, and the temperature inside the submarine immediately began to rise.

"Premier Cao, I suggest we go up immediately. It's too dangerous here." Li Shan proposed to Premier Cao again.

This time, Premier Cao didn't insist any more and said, "OK."

Submarine began to float, but at this time, Leng fan found that the huge shark moved to this side, and the speed was very fast, with a strong offensive.

"Here it comes. It's a shark." Leng Fan said to them.

With these words, people are worried. They are at the bottom of the sea now, but they don't have any defensive means. If the other party really wants to attack them, they can only be forced to accept the impact.

"I've seen him all." Cried Li Shan.

Everyone saw that a huge shark was moving rapidly in the water under the light.

"This is the ancient giant toothed shark," said Cao.

Professor Tai also recognized that it was a megatoothed shark, but he was more worried. Megatoothed sharks are very fierce creatures. How should they face them now?

"Don't worry about it, we'll go straight up." Leng fan to Li Shandao.

Li Shan has no choice but to continue to float. I don't know if the giant toothed shark will take the initiative to hit them? At the moment, sweating, he only saw the megatoothed shark coming towards them. He was about to hit them.

Leng fan sat at the back, only to see his eyes a bright, an invisible gas field scattered.

"Look, the giant toothed shark has turned around. You see how fast it runs," Professor Tai said in a loud voice. Then he saw the giant toothed shark turn around and swim faster.

A boat of people, except Leng fan, were very surprised why the megatoothed shark would turn around, and from its reaction, it was obviously afraid of something.

"The shark must have smelled more powerful creatures, so it dared to turn around and run away," Cao said. We can't delay any longer. We'll go up right now. We'll go right to this right and wrong place for the time being. "

Two hours later, the submarine finally floated to the shoreline of Shanghai, and everyone was relieved.

After President Cao stepped on the deck of the scientific research ship, he walked down the road“ This sinking is very controversial. We have discovered ancient creatures. Our test on the bottom of the sea is very valuable. "

Professor Tai nodded and said, "yes, but we can find more. President Cao, I apply for rest and continue to sink. We can find more information to prove the existence of the last generation of human beings. "

President Cao also meant that, but Captain Li Shan was a little reluctant. He said: "it's too dangerous. I know the experts' desire for the underwater world, but we can't effectively protect ourselves at present. I suggest ending the postgraduate entrance examination. We will continue to explore when technology is stronger and better equipment is developed. "

Professor Tai didn't want to, because he knew that if he gave up this time, he would never have a chance to study again in his life. He said, "no, we have to continue. We can study what you said, not necessarily without solutions."

Leng fan then said to President Cao: "President Cao, sword gas has no resistance in the water. You can install the enhanced version of sword gas gun on the submarine. In case of danger, we can use it for self-defense."

Dean Cao brightened his eyes and said, "yes, how can I forget this? The sword Qi is not hindered by the pressure of water." Then he said to Leng fan, "young man, you have made a good suggestion. OK, I will go to prepare now. Just on board, there is a set of sword gas gun equipment, which should not be used much to install on the submarine

Time. "

After President Cao finished, he immediately began to arrange for people to install the Jian Qi gun.
