Lu Ao returned to the boat and drove the boat away from the position where Captain Gu and the others had mistakenly found the boat. He did not stop until they had sailed more than ten nautical miles.

Song Zhou had already arrived with a lunch box, and Lu Ao heard the noise.

Lu Ao turned off the engine, parked the boat, and ran to the lounge to find him.

Song Zhou didn't say anything, he raised his head slightly and said, "Go wash your hands and get ready to eat."

"Oh." Lu Ao went out, too lazy to open the drinking water. He looked around to make sure there was no one nearby, and quietly stretched out his hand.

A white cloud quickly came over the ship, and it started to rain over the ship.

Lu Ao stretched out his hand, washed it several times, and then used his power to push the cloud to go somewhere else.

Song Zhou saw him being lazy and handed him a tissue to wipe his hands, "You've been busy all afternoon?"

"Fortunately, I came here to dive just after three o'clock." Lu Ao said, "I'm not too tired from diving. I feel okay."

"What do the people over there say? Are you still going tomorrow?"

"It will take another day. I think I will be able to find the sunken ship tomorrow." Lu Ao promised, "I will go back whether I can find the sunken ship tomorrow or not."

"It's not that I won't let you help." Song Zhou pondered, "Although you have a deep connection with mankind, it's not enough to keep helping like this. Your existence has already affected China's destiny."

Lu Ao was startled, his hand stopped, and he looked up at him in shock, "Is it so serious?"

"Do you think the last dragon in this world is rare?"

"Oh." Lu Ao picked up a chicken wing and asked carefully, "Is this a good thing or a bad thing?"

"It's a bad thing for you, but it may not be much better for China. If you sow causes, you will get results. If you save effort here, you will have to make up for it elsewhere in the future. It won't be much easier."

Lu Ao put down his chopsticks and responded solemnly, "I understand, and I won't help blindly in the future."

"It's not that I won't let you help at all. Don't do major things that obviously have an impact on China's national destiny, such as finding computers, catching poachers, salvaging cultural relics, etc. Other things are fine."

Lu Ao can understand the computer thing, it contains important scientific research information.

Regarding the poachers, the poachers' boats and submersibles may have been impounded. Lu Ao also understood what new technologies could be obtained.

But what about salvaging cultural relics?

Lu Ao frowned, "How can the salvage of cultural relics be related to the entire national destiny? This is not a particularly important cultural relic, is it?"

"Cultural relics are not particularly important, but this may promote a transformation in China, from focusing on land resources to developing the ocean." Song Zhou asked, "Don't you think there is anything wrong with the team leader personally leading the team to salvage the sunken ship?

?”

Lu Ao hesitated, "Don't they happen to be on duty at sea and come over to carry out tasks if there are tasks nearby?"

"How free does the leader of a regiment have to be before he can bring dozens of soldiers over to do a mission?"

Lu Ao was asked.

It's not that he didn't feel something was wrong before, it's just that the other person was a member of Captain Gu, so there was nothing suspicious about him.

The education Lu Ao received since he was a child told him not to inquire about things that shouldn't be asked.

He didn't ask, nor did he think about the deeper meaning.

The main thing is that no matter what's inside, it's basically none of his business.

Song Zhou gave him a poached egg and said, "Concentrate on eating first, and think slowly after eating."

Lu Ao took a deep breath and started eating.

After the two of them finished eating, Song Zhou didn't leave and simply stayed on the boat.

Life on the boat was still quite boring, but there were only two of them on the boat. They looked at the stars, the moon, fished and chatted, so they didn’t find the time difficult.

Early the next morning, after the two of them washed up, Song Zhou went to the cafeteria in their small courtyard and came back with breakfast.

Omelette, steamed buns, soy milk, fried dough sticks, rice rolls, fried noodles, side dishes... Songzhou brought back many kinds of breakfast, and all the breakfast items were still steaming hot.

The sea was a little cold in the early morning, so Lu Ao felt very comfortable after having such a meal.

After breakfast, Song Zhou went to work with his food box, while Lu Ao drove the boat back to visit the captain and his companions.

Captain Gu and the others transferred the submersible overnight, and now the submersible has gone down for one round.

They still couldn't find the location of the shipwreck, but they saw more cultural relics scattered on the seabed.

These cultural relics are so scattered that even if they see them with a submersible, they won't be able to recover them.

A large number of cultural relics have been able to prove that a tragedy must have occurred here.

It's just that no one knows where the tragedy happened or what caused it.

Seeing Lu Ao, Xiao Du called him from afar, "Brother Lu, have you had breakfast? We had fried rice noodles today and left an omelette for you. Do you want some?"

"No, I've eaten. You can eat."

While chatting, Lu Ao's small boat approached the big ship.

Xiao Du, Xiang Xingchang and others rushed over to help him drag the boat up.

Captain Gu appeared on the deck and raised his hand to greet him, "Lu Ao, come and take a look. Guess where our shipwreck is?"

"Wait a minute." Lu Ao walked over to him and asked, "Have you explored the bottom of the sea in the past two days?"

"Yes, there is sonar imaging data, but it can only show the general topography of the seabed, and details such as sunken ships and cultural relics cannot be revealed."

Lu Ao said: "It doesn't matter, just show me the terrain map."

Commander Gu personally took him in to see the soldiers inside operating the equipment.

Humanity's scientific and technological level is not very advanced yet, and we know very little about the ocean.

Sea water and air are completely different things. Some technologies used on land are useless once they reach the sea.

Sonar imaging technology is a technology specifically used for ocean exploration, but this technology is not very mature.

Lu Ao could roughly tell which areas were raised and which areas were sunken by looking at the deep and light patches of color underneath.

Lu Ao looked at it for a while and asked, "Are there any clearer pictures?"

The technician was a little nervous and shook his head quickly.

Lu Ao: "What is the scale of this picture?"

"One centimeter is equal to three hundred meters." The technician said, "We have basically explored all the sea areas you guessed. This is the first point, and no suspicious objects were found."

Lu Ao: "That's not necessarily the case."

Captain Gu immediately asked: "What did you find?"

"I'll take a look again."

Lu Ao looked at it for a long time, and finally pointed to a raised area on the picture, "I think the possibility of a shipwreck is higher here?"

The technician immediately asked: "Why?"

"It feels like it." Lu Ao said, "Looking at the currents and terrain, combined, I think it should be here."

Captain Gu immediately decided, "Then let's try this location first. If it doesn't work, we can change the location for exploration."

"Let's go take a look first." Lu Ao said, "Give me a diving suit and I'll go down in person."

"How about you go down in the submersible today? Let's save some time?"

When people dive, their entire body is basically exposed to sea water.

The deeper you dive, the greater the pressure on a person. At a depth of more than 100 meters, a person's lungs may shrink to an extremely small size.

In order to prevent diver's disease, every diver needs to adjust his speed when ascending and ascend slowly, even if it takes two hours, five hours, or even a day.

Lu Ao's trip would take him at least two hours in order not to arouse suspicion.

If you use a submersible, about 17 or 18 minutes is enough.

People inside the submersible do not have to worry about the troubles caused by seawater pressure to the human body. They can dive and rise very quickly.

Lu Ao didn't object.

Soon, Captain Gu ordered the boat to be driven to the location designated by Lu Ao. He sent a professional operator and an archaeological expert to accompany Lu Ao.

The entire dive was videotaped this time, so there was no need to rely solely on the divers' dictation like yesterday, and everyone could slowly imagine the dive.

A small submersible enters the water.

Lu Ao and the others dived down at a speed of more than 20 meters per minute.

Soon, the sea outside the porthole changed from gray-blue to dark blue, and then to almost pitch black.

Glowing fish and other sea creatures began to appear outside.

The operator had to turn on the light, while the archaeologist quickly recorded and muttered something.

Lu Ao looked out the porthole intently.

"Teacher Lu, there are still ten meters left."

"Keep going, control it, don't go all the way down, I suspect there is something in the mud."

"No problem." The operator controlled the submersible to descend slowly.
