We all know that greed does not end well, but there are very few people who can restrain their greed.

In the dark chamber of the shipwreck at the bottom of the sea, I encountered a sea ghost, but I didn't expect that the warrior dagger of the Sea Yama was actually forged from its Nether Flame and the black iron of the Eastern Sea, but fortunately I carried the equipment of the Heavenly Commander Na Yong and pierced its skull with a single shot.

After rescuing my colleague Yu Xingyan, I quickly escaped from the shipwreck, and when the ship landed, it turned into ashes, and Xiao Zhu, who was guarding my body on it, was stunned, and the bottom of the sea suddenly collapsed, revealing a large hole.

My soul quickly merged with my body, and I told Xiao Zhu to get out of here quickly.

The large cavern that collapsed behind him created a whirlpool that pumped the sea water and all living things into it.

After returning to the submarine, I took off my diving mask, and Xiao Zhu immediately asked me, "What about the shipwreck treasure you are talking about?" ”

I exhaled slowly and said, "What more treasure, it's a blessing to be able to bring my life back!" ”

Sitting on the steps of the decompression chamber, I was taking off my diving suit when Zheng Xiumin and Yingnan Yoshio hurried over, the former was relieved to see us return safely, but the latter said to me: "Yuan Sang, don't move!" ”

He plucked some bits and pieces of stones from my mask and wetsuit and rubbed them carefully on my clothes, which gave off a golden color.

Xiao Zhu and he were stunned, and Ying Nan was surprised: "Yuan Sang, it's a gold nugget, where have you been?" ”

I threw the diving device on the steps, Yingnan immediately knelt down and carefully collected the gold nuggets, Xiao Zhu hurriedly shook his diving equipment, but only shook off some of the sea sand.

Zheng Xiumin closed the inner door of the decompression chamber and said to us: "We have to get close to the coastline as soon as possible, people will go crazy if they stay in the submarine for a long time!" ”

The two of us returned to the cockpit, and I continued to activate the submarine's autopilot system, and the submarine's engines continued to work, carrying us towards Chiba Prefecture, Japan.

Ying Nan and Xiao Zhu returned to the cockpit with a bag of gold sand, and Zheng Xiumin said to the two: "These gold sand and that coral will trouble Ying Nanjun to help us, and the money will be used to arrange for us to leave Japan, and the rest of the money will be yours!" ”

The Japanese was overjoyed when he heard this, and hurriedly nodded his head in agreement, but Xiao Zhu looked confused and asked us: "Are we going to return to the motherland penniless?" ”

Zheng Xiumin didn't answer, but said to him: "Xiao Zhu, you first follow Ying Nanjun to learn the control of the submarine, I have something to say to Xiao Yuan!" ”

After returning to the rest cabin, Zheng Xiumin sat on the bed and said to me: "Senior brother, there are two ways for us to go after we arrive in Chiba Prefecture in Japan, one is to smuggle back to China with the help of Hideo Yoshio, and the other is to continue to take a submarine to the East China Sea to meet our comrades. Is this Japanese reliable? ”

I replied slowly: "I'm not sure, Yingnan was originally a descendant of the Japanese army invading China, he lived in Wuhan for two years, came back and became an American citizen, and was imprisoned for stealing information, I don't think he will betray us!" ”

Zheng Xiumin said: "I don't like the Japanese since I was a child, I always feel that the Japanese are very insidious and cunning, and vicious, in case he betrays us or abandons us, our situation in Japan is more dangerous!" ”

"Then after we replenish the power of the submarine in the port of Chiba Prefecture, we will continue to take the submarine to our East China Sea, so that it is more hidden!"

Zheng Xiumin expressed her worries and concerns, this submarine was leased by Jiao Yi from the ship repair factory using her friendship, not to mention the deposit, the rent alone costs 2,000 US dollars per day, so it is best to return it as soon as possible, otherwise Jiao Yi and her parents will definitely go bankrupt.

After the two of us agreed, we unanimously decided to wait for the landing, and Zheng Xiumin immediately called his superiors to see how the superiors dealt with it?

"If the higher-ups can't send someone to pick us up, then we have to find a way to return to our homeland on our own."

After hearing this, I asked, "Since your superiors know that you have rescued me and Xiao Zhu, why won't you send someone to pick us up and return to China?" ”

Zheng Xiumin smiled bitterly and replied slowly: "The superiors have already determined that you and Xiao Zhu have died, and they are in the need of secrecy, so this rescue operation is completely my personal behavior, Lao Hu and my cousin are still staying in Hawaii, and they can be regarded as hostages of our chartered submarine." ”

I comforted her: "Don't worry, money is not a problem, with my current ability, we only need to take a small amount of treasure under the sea, and we can get rich." ”

"But I don't want you to risk it, you managed to escape from Alcatraz prison!"

I hugged Zheng Xiumin tightly, there are many people in this world who are worried about me, but there are not many people who can take the risk to rescue me in person.

We have nothing to do in the submarine except to eat and sleep, so we follow Hideo Yoshio to learn to operate the submarine, in fact, this submarine is completely electronic and easy to control, but it is a little difficult to maintain, and non-professionals are not competent.

When the submarine was about to run out of fuel, we were still thousands of nautical miles from Chiba Prefecture.

The submarine was stranded on the bottom of the sea in eastern Japan, and Yingnan was at a loss, so I lay down in my room to rest, and then asked Yu Xingyan, who had recovered, about what to do.

Yu Xingyan said: "I know that the sea is rich in oil and natural gas, but how to inject it into the submarine and turn it into the power of the submarine is not clear. ”

"Let's go and give it a try, we can't just be trapped here for the rest of our lives!" I issued an initiative and took the souls of Zheng Xiumin and Yu Xingyan and floated out of the submarine.

As I wandered on the ocean floor, I closed my eyes and looked deeper into the bottom of the sea, and through the rock formations at the bottom of the sea, I saw the oil and gas hidden beneath the rock formations.

Some natural gas even rises to the surface of the sea through cracks in rock formations.

I flashed my flame gun and ice shield and dug down the cracks in the rock formations under the sea, Yu Xingyan used her mana to condense the spilled natural gas, and Zheng Xiumin opened the fuel tank of the submarine.

It is not clear to me whether this submarine, which uses oil and gas as a hybrid, will continue to operate with only unpurified gas?

But as a result of our efforts, the fuel tanks of the submarine were quickly filled.

We returned to the submarine, Zheng Xiumin and I fused with the body, and then went to the control compartment to try to ignite, the submarine's engine continued to work, Xiao Zhu and Yingnan showed surprised expressions, but the submarine slowed down significantly in the process, and it shook badly.

I asked Yingnan about the fuel system, and he gave us an easy-to-understand explanation, the working principle of the engine we have all learned in high school physics, as the engine design becomes more and more sophisticated, the horsepower is more and more demanding, the purity of the fuel is more and more demanding.

Of course, the mixture of diesel and gasoline is not impossible, but it is very harmful to the engine, the rough fuel is more damaging to the cylinder wall of the engine, and the impurities produced by combustion accumulate in the engine cylinder, which is easy to make the engine fail, and the pure natural gas is used as fuel, so the horsepower of the engine will be weakened.

Zheng Xiumin said: "There is oil on the bottom of the sea, but it cannot be refined!" ”

I asked Hideo about the principle of crude oil refining, and as long as we understand this, it is not impossible to refine crude oil with our superpowers.
