During the time that Chen Jingfeng left, Liuyun was busy for a while, consumed the collected porcelain clay, and made a batch of more exquisite porcelain, which was given to the rest of the people on the island as a souvenir.

After making porcelain, Duan Peng, the chicken thief, didn't let Liuyun idle: he took a large bag of waste drill bits from nowhere, and asked Liuyun to make a batch of knives......

Looking at the triumphant smile on Duan Peng's face, Liuyun couldn't help but laugh: "Boss, I don't know where you heard that tool steel can make knives, and tool steel can indeed make knives......"

The smug look on Duan Peng's face became even greater......

"But," Liuyun stared at Duan Peng with a smile, "It's a pity that you found these tool steels and couldn't make knives." ”

Duan Peng's smile stopped abruptly......

"Why?"

Liuyun smiled and looked at Duan Peng, who was confused: "Do you know why the Type 56 bayonet is made into a three-edged stab?" ”

Duan Peng frowned: "I heard that the toughness of the steel is insufficient, so I can only use the hardness to make up." ”

Liuyun nodded: "If you want a three-edged thorn, you can also make it for you, but if you want to make it into an ordinary style, it will be easy to break the blade." ”

"What then?"

Duan Peng was a little panicked......

"You go get a short section of heavy steel rails, and I'll build you a batch of similar ones to Li Kang's."

Duan Peng's eyes lit up: Li Kang's three knives are good things, he has been sharpening them for a long time in the past few years, and Liuyun has not let go, so he will build a second batch of ......

Duan Peng hummed a little song and left......

Liuyun glanced at the big drill bit on the ground and estimated: everyone in the team should have a surplus......

Liuyun's eyes lit up, and he thought of an artifact, a variant of the Swiss Army Knife, a combination tool knife.

Because he doesn't suffer from procrastination, as long as he has a new idea, Liuyun will put it into action.

When Duan Peng came back with a large piece of rails, Liuyun had already completed the scheme "design" of the combined tool knife and the multi-skill tactical knife.

The scheme of the multi-functional tactical knife is relatively simple, and it is directly copied from a certain version of the multi-functional tactical knife of a certain leopard.

The combination tool knife is relatively troublesome, and Liuyun Cottage has three versions: firearm maintenance, bomb disposal and demining and mechanical maintenance.

Seeing the scheme of the multi-functional tactical knife, Duan Peng was not surprised, he had already seen similar ones; Seeing the Swiss Army knife with pliers, scissors and screwdrivers, Duan Peng was a little surprised: he also had one in his hand, but he didn't have the three full functions in front of him......

So, Duan Peng waved his hand: the plan was passed, and the product entered the trial production stage......

Then, the members of Liangshan, who were hungry for sabers, were caught by Liuyun: cleaning drill bits and rails, guarding the heating furnace, and clamping forgings with pliers......

The manufacturing process of Liangshan team members is clear: hot forging of two different materials of steel into plates, welding them together, and then constantly folding and hot forging ......

After the small sample is formed, it is forged and then tested for tool performance......

When the required tactical knives were completed, Duan Peng suddenly remembered one thing: all the tactical knives were three-no products, and there was not even a mark. Then, Duan Peng reported the situation to Liuyun......

"I said, little doctor, are we going to put a mark on the knife or something?"

Liuyun smiled, picked up the brush, wrote a line on the prescription note, blew it and handed it to Duan Peng......

"Will you show your sword when you meet the enemy? Good! That's it! ”

Duan Peng's face was full of surprise, and he kept nodding his head......

"Alas, by the way, are you going to make this sentence into a steel seal, or do you want to engrave it directly on the knife surface?"

Liuyun smiled: "If you want a steel seal, just say it!" ”

"Okay," Duan Peng sighed, "Make a steel seal, I also want to help those brothers who have returned to the building, and also prepare a batch of knives." ”

"I feel honored to be a member of Yangsan!" Liuyun sighed, "Do combination tools need to be stamped as well?" ”

"It's all the same!"

Then, Liuyun needs to make two steel seals......

Compared with tactical knives, the production of combination tool knives is more cumbersome: each knife takes more time than the entire knife of tactical knives just for blanking; Some parts also need to be mechanically cut and sanded......

Even if Liuyun used all his experience in the production of knives, with the assistance of others, it took more than a month to produce a sufficient number of combination knives.

By the time Liuyun was freed from the tedious task, it was already the end of 1972, and Chen Jingfeng had been away from the island for more than three months.

Just when Duan Peng was glad that Chen Jingfeng gave up Liuyun, Chen Jingfeng landed on the island again......

According to the rules of the island, Liuyun leaves the island in the middle of the night......

When he left the island, Liuyun only took away his books, stationery and some small gifts made in recent times.

Chen Jingfeng glanced back at the dark island, and then at Liuyun who was walking in front with a flashlight and didn't say a word: "Xiaoyun, don't you really need to say goodbye to them?" ”

"Those who have lost their souls, only farewell!"

After the two of them boarded the ship, there was a sudden light on the island, and the only light came from Liuyun's hut......

In the room, Duan Peng looked at the "Decision on Rehabilitating Comrade Li Yunlong" on the side of the table in a daze......

It took a long time for Duan Peng to come back to his senses and slap the table to pieces with a hateful palm: this was the second time in his life that he felt his powerlessness, and the last time was five years ago......

It wasn't long before the telegraph on duty sounded the battle alarm, and a short, but loud buzz echoed throughout the island......

"Old Duan, good news!" Lin Han rushed to Duan Peng, "The old head of the regiment ...... him"

Duan Peng cried with a sad face, and raised the red-headed document in his hand......

In the second half of the night, Chen Jingfeng led Liuyun to the guest house of the speedboat brigade, opened a room, and returned to the brigade after explaining.

And Liuyun, because of the new environment, didn't just fall asleep until early in the morning......

"Wow......"

A sharp knock on the door woke Liuyun from his deep sleep......

Liuyun rubbed his eyes, pulled his shoes, walked to the door, pulled the bolt, and opened the door to see a middle-aged woman with a smile on her face, standing at the door nervously......

"Let me guess, you're Xiaoyun?"

Liuyun nodded with a wry smile, and shouted "Aunt Liu" crisply.

Chen Jingfeng's wife, Liu Xiaohui, stroked Liuyun's head with a smile: "The reaction is quite fast, your Uncle Chen asked me to come and pick you up!" ”

"Oh, please come in!"

Liuyun pulled the door open in a daze and motioned for Liu Xiaohui to come in......

"No need, there's still hot food at home," Liu Xiaohui patted Liuyun's shoulder with a smile, "Clean up and go home with me!" ”

Go home?

Familiar and unfamiliar words, but very warm, isn't it? The corners of Liuyun's mouth curled......

After packing his backpack, Liuyun took the more fashionable transportation of this era, the 28 big truck, and braved the sea breeze to rush to his new home......
