Under the opening of Sui Yuan, Lin Feng and the others only heard a snap, and then, the black box was divided into two, and then a few parts fell out, and Sui Yuan put away the parts with care, and then slowly separated the black box.

With two snaps, two items fell out of the black box, one was a diary, which should be the captain's nautical diary, and the other was a square item, although it was square, but Lin Feng still felt a little familiar.

Suddenly, Lin Feng thought of where he had seen this item, and immediately took out a round object from the ring, one in each hand, and looked at it. Sure enough, these two items were very imaginative, but the shapes were different, Lin Feng knew that he would definitely not be able to open them, so he put the two items into the ring and picked up the diary.

At the first glance, everyone saw that there was a name written inside, and not surprisingly, this name was the name of the captain.

'Deng Changxian's Voyage Diary' September 16, 2038 in the Gregorian calendar, today is the eighteenth day of the disaster, I have been traveling to the bottom of the sea with the Shark for eighteen days, except for getting a square metal in one position, I have not obtained any items.

On September 28th, thirty days, the thirty days of the great tribulation, since the last time I saw the sun, I have been wandering the bottom of the sea, except for fish, shrimp and crabs, there is an eerie sea water, and I don't know when I will receive the news of victory.

On September 29th, the thirty-first day, the thirty-first day of the great calamity, today received news from the organization, humanity has failed, many people have died, but there should be people who can survive, and I hope everyone will survive.

On November 8th, the seventy-first day of the great tribulation, we had run out of food, hundreds of soldiers had died ninety percent, this may be the last time I recorded my voyage, our fighters were starving to death, because the power of the submarine could no longer maintain the power supply, and we faced only one result, and that was death.

On November 9, the seventy-second day of the great tribulation, he died, all dead......

The diary ended here, but what surprised Lin Feng was that there were actually a lot of drawings carved on the back of the diary, and seeing these drawings, everyone present was dumbfounded, except for Hilton, of course.

"This, this, this won't be, it won't be the production of a submarine!" Yu Chiyan muttered.

"It's gone, it's been made, we're going to be developed, hahaha!" Tang Yin laughed.

"Boss, this is really a drawing of a submarine, but why is it drawn in a diary?" casually asked suspiciously.

At this time, Lin Feng only reacted, yes, follow what Yuan said, this is drawn on the diary, in this case, can it be made?

Everyone's hearts were hit by Sui Yuan, although he didn't blame Sui Yuan, but why did he want to say it, so Lin Feng's room heard a terrible scream, and many players who listened to it only shivered in their hearts.

After nine days, Lin Feng and the others finally returned to the fortress, and when the pirate ship was halfway there, they were sent back to their pirate island by Suiyuan, and as for Suiyuan, they followed themselves to the Super Battle Fortress.

"Wow, that's a lot of people!" This was the first sentence of getting off the boat casually, but it attracted the sideways glances of countless people.

"Look, the boss doesn't know where to find a fool, and he hasn't even seen anyone!" A player said to the people next to him.

"That's right, I haven't even seen people, did I live with wild beasts before?" This player responds.

"You two be quiet, let others hear, and then reach the ears of the boss, and be careful to pluck your skin." Another player reminded.

"Yes, yes!" After that, the three of them quietly stared at Lin Feng, who had returned.

Lin Feng's side, after everything was done, he came to Wang Kui and handed the diary to Wang Kui, after Wang Kui saw it, he stared at Lin Feng with a shocked face: "Boss, I blinded my 24K titanium eyes, this is the production map of the submarine?" ”

Lin Feng shook his head: "It's not a production map, it should be an analysis map, whether it can be produced or not, everything depends on you, of course, if you make it, I will give you a big red envelope, no less than eleven digits." ”

Wang Kui's heart jumped, and he left with the diary, and in the next ten days, Wang Kui handed over everything to his assistant, and he buried himself in studying the submarine.

Seeing Wang Kui's appearance, Lin Feng knew that his big red envelope moved him, and sure enough, as Tang Yin said, Wang Kui's favorite thing was money.

After more than ten days, Lin Feng finally received a prompt from the system that his pursuit order had been officially canceled, which meant that the tens of billions he had robbed were officially owned by himself.

In two months, the world is rarely in a period of peace, Lin Feng has made nearly 10,000 ironclad warships in these two months, and the research of submarines has also entered an intense stage.

The aircraft carrier has also entered the production stage, and in two months, Lin Feng has once again manufactured five factories and three seaports, plus the previous two seaports and four factories, Lin Feng now has a total of five seaports and nine factories, and the manufacturing capacity has greatly increased.

"Brother-in-law, the aircraft carrier has also entered the manufacturing period, and I believe that soon, we will get the first aircraft carrier." Tang Yin said with a smile.

Lin Feng nodded and asked, "What about the production of submarines?" ”

"We have already started to prepare, and there is still the most difficult hurdle, as long as we overcome it, we can manufacture it in large quantities." Tang Yin responded.

"Very good, brother-in-law, you go and release the news, just say, we have 8,000 ironclad warships to sell, and in five days, there will be an auction, and the bigger the public opinion of this news, the better." Lin Feng said.

"Brother-in-law, we only have 10,000 ships in total, and you sold 8,000 ships at one time, what if the enemy buys them to attack us?" Tang Yin asked suspiciously.

"Hehe, 8,000 ironclad warships want to attack us, do you think they will take our city?" Lin Feng said with a smile.

Tang Yin nodded: "Also, eight thousand ironclad battleships are really not enough for us to see, in this way, we can not only return the funds, but also increase our income, in the past two months, I can't make ends meet!" Tang Yin said, patting his waist bag.

"Let's go, the sooner the auction takes place, the better it will be for us, and the more we will earn!" Lin Feng said. Tang Yin immediately looked for Qualkek, and Quarkek was able to do this matter, after all, he was an NPC of the system.
