Siheyuan: Sap is the last word

System: "Of course! The Spiritual Spring can enhance all the host's skills, including benchwork skills."

He Yudong was ecstatic. With the help of Lingquan, he believed that he could complete this mysterious mission!

The next morning, Li Weiguo came to the dormitory and took him to a secret underground workshop.

There was a huge machine in the workshop, covered with thick canvas.

Li Weiguo pointed at the machine and said, "This is the equipment you need to repair. It is very important to the country. You must fix it!"

He Yudong walked forward, lifted the canvas, and was stunned.

This...what the hell is this?

The appearance of this machine is extremely strange and full of science fiction, like a product of some future technology.

He had a feeling that this mission was definitely not easy...

He Yudong was stunned for a full minute before he found his voice: "Military region? Important mission? National security?" He asked a series of questions like a string of cannonballs.

Li Weiguo nodded, his expression serious: "Yes, this is a matter of great importance and cannot be delayed. We have reviewed your information in detail, and your technical level fully meets our requirements. Now, please come with us immediately."

He Yudong's heart was in turmoil. How could such a pie in the sky fall on his head? He subconsciously wanted to refuse. After all, there were still a lot of things to deal with in the courtyard. Yi Zhonghai, Jia Zhangshi, and Sha Zhu might be up to something bad.

But on second thought, this is a military district! It is a matter of national security! If I refuse, wouldn’t I become a sinner of the country? Besides, if I go to the military district, the emperor is far away, and I can avoid those vampires in the courtyard.

Thinking of this, He Yudong gritted his teeth and said, "Okay! I'll go with you!"

Before leaving, He Yudong went to the supply and marketing cooperative, bought two bottles of good wine and a bag of peanuts, and went straight to the deaf old lady's house.

"Grandma, I have to go out for something, and it may take a long time. You are alone at home, so please take care of yourself." He Yudong put the wine and peanuts on the table.

The deaf old lady squinted her eyes and smiled kindly: "Go ahead, young people should go out and try their luck. Don't worry about me, I'm in good health."

He Yudong gave a few more instructions before he felt at ease and followed Li Weiguo out of the courtyard.

Watching He Yudong's receding back, the deaf old lady's cloudy eyes flashed a gleam of light. She walked to the window tremblingly with a cane, watching He Yudong get on the military jeep and disappear at the entrance of the alley.

"This kid, if he doesn't make a name for himself, he will be a big hit..." The deaf old lady murmured to herself, with a meaningful smile on her lips.

......

Military compound.

He Yudong followed Li Weiguo to a heavily guarded laboratory.

"Comrade He Yudong, this is our chief engineer, Zhao Guoqiang," Li Weiguo introduced.

Zhao Guoqiang is an old man in his 50s, with gray hair, but he is vigorous and his eyes are full of wisdom. He looked He Yudong up and down, his eyes full of admiration: "It is true that heroes emerge from youth! He has become a fifth-level fitter at such a young age, and he has a bright future!"

He Yudong smiled modestly: "Mr. Zhao, thank you for the compliment. I'm just a little luckier."

"Luck is also part of strength." Zhao Guoqiang patted He Yudong on the shoulder, "Young man, do a good job! This mission is very important, and the country's hope rests on you!"

He Yudong suddenly felt the burden on his shoulders was heavy.

"Engineer Zhao, what is the specific task?" He Yudong asked impatiently.

Zhao Guoqiang pointed to a huge machine in the center of the laboratory: "See that machine? That's our latest 'particle accelerator'. Its function is..."

Zhao Guoqiang explained in detail the principles and functions of the particle accelerator, as well as the goal of this mission - to use the particle accelerator to open a passage to another world!

He Yudong was stunned. Why did this plot feel a bit fantasy?

"Another world? Does it really exist?" He Yudong couldn't help but ask.

Zhao Guoqiang smiled mysteriously: “Believe it or not, but we have already obtained solid evidence. This alien world contains huge energy and resources. If we can successfully open the channel, it will have a huge boost to the development of science and technology in our country!”

He Yudong took a deep breath. He felt like he was dreaming. He was just an ordinary fitter, but he was actually involved in such a sci-fi project!

In the next few days, He Yudong began to learn how to operate the particle accelerator under the guidance of Zhao Guoqiang.

With the blessing of the spiritual spring, He Yudong learned at an amazing speed and quickly mastered the operation of the particle accelerator.

"What a genius!" Zhao Guoqiang praised He Yudong, "I have taught countless students, but you are the first one with such talent!"

Everything is ready and the day to start the particle accelerator has finally arrived.

The atmosphere in the laboratory was tense and solemn.

He Yudong stood in front of the operating table, took a deep breath, and pressed the start button.

"Om-"

The particle accelerator emitted a loud roar, and the lights in the laboratory began to flicker.

Suddenly, a dazzling white light shot out from the particle accelerator and shot straight into the sky!

Then, everything in the laboratory began to distort and deform...

"what--"

He Yudong screamed and woke up from his sleep. He found himself lying on the bed in the military district guesthouse, covered in cold sweat.

"It turned out to be a dream..." He Yudong wiped the sweat from his forehead, but he felt vaguely in his heart that this dream seemed to indicate something...

The next day, He Yudong came to the laboratory, but found the atmosphere unusually solemn. Zhao Guoqiang's face was livid, holding a report in his hand, and he said nothing.

"Mr. Zhao, what's wrong?" He Yudong asked with concern.

Zhao Guoqiang raised his head, his eyes full of helplessness and frustration: “The particle accelerator…is out of control…”

"What?!" He Yudong was shocked. "How could he lose control? He was fine yesterday!"

“We don’t know the reason either…” Zhao Guoqiang sighed, “Now, the particle accelerator is constantly absorbing energy. If we can’t stop it in time, the consequences will be disastrous!”

"Then what should we do?" He Yudong asked anxiously.

Zhao Guoqiang gritted his teeth: “There is only one way now…that is to manually shut down the core device of the particle accelerator!”

"Manual shutdown?" He Yudong's face changed. "That's too dangerous! The radiation intensity of the core device is extremely high. Anyone who goes in will surely die!"

Zhao Guoqiang nodded heavily: “I know, but now there is no other choice…”

There was dead silence in the laboratory.

Who is willing to die?

At this moment, He Yudong stood up...

He Yudong was stunned. Military region? Important mission? He subconsciously touched the club in his pocket. Can he take this thing with him?

"Comrade Li Weiguo, is this mission...dangerous?" He Yudong asked tentatively.

Li Weiguo raised his lips slightly, revealing a meaningful smile: "Dangerous? Of course it's dangerous! But if it wasn't dangerous, why would we choose you? Comrade He Yudong, you are carefully selected by us, a level 5 fitter! This is a matter of national security, we dare not use ordinary people."

This made He Yudong feel itchy inside. Danger is good, it is exciting! He likes this kind of exciting feeling! With the system in hand, there is nothing to be afraid of!

"Okay! Comrade Li Weiguo, I accept this task!" He Yudong patted his chest and said proudly.

Li Weiguo nodded with satisfaction: "Okay! It turns out that heroes emerge from youth! Gather at the factory gate at 8 o'clock tomorrow morning. A special car will pick you up."

When He Yudong returned to the courtyard, Jia Zhang was sitting at the door eating melon seeds. When she saw He Yudong coming back, she immediately said in a sarcastic tone, "Hey, isn't this our fifth-level fitter He Yudong? He got promoted, what a big deal!"

He Yudong didn't bother to pay attention to her and went straight to his room.

"Hey, He Yudong, now that you've been promoted to level five fitter, shouldn't you treat everyone in the compound to a meal? Don't forget, you grew up eating at many people's houses!" Jia Zhang kept shouting.

He Yudong stopped, turned around, and looked at Jia Zhang with a half-smile: "Jia Zhang, you have a good memory. I really forgot about this. But, what does my dinner have to do with you? You didn't even give me a bite to eat!"

Jia Zhang was choked and speechless, her face flushed red.

"You...you ungrateful bastard!" Jia Zhang pointed at He Yudong's nose and cursed.

He Yudong sneered: "Ungrateful? If you really want to eat my food, beg me! Maybe I'll reward you with a bite if I'm happy."

Jia Zhang was so angry that she was shaking all over, and the finger she was pointing at He Yudong kept trembling.

"you you......"

He Yudong was too lazy to talk to her anymore and turned back to the house.

After closing the door, He Yudong took out a club from the system space and weighed it a few times.

"Old buddy, I'm counting on you again this time!"

The next morning, He Yudong arrived at the factory gate on time, and a military green jeep was already waiting there.

Li Weiguo got out of the car, saw He Yudong, and said with a smile: "Comrade He Yudong, get in the car!"

He Yudong got in the car and the jeep sped out of the city.

"Comrade Li Weiguo, where are we going?" He Yudong asked curiously.

"Go to a secret base." Li Weiguo said mysteriously.

The car drove for a long time and finally stopped in a hidden valley.

Li Weiguo took He Yudong into a cave, and there was a different world inside the cave, it turned out to be a huge underground base!

"Welcome to the 'Longteng' base!" Li Weiguo pointed to a huge machine in the center of the base and said, "This is the target of our mission this time - the 'Longteng' device!"

He Yudong looked at this high-tech machine with curiosity in his heart.

"What exactly is this 'Dragon Soar' device used for?" He Yudong asked.

"This is a top state secret. I can only tell you that this machine is related to the future of the country!" Li Weiguo said seriously, "Your mission is to repair a key component of this machine."

Li Weiguo took He Yudong to the side of the machine, pointed to a complicated part and said, "This part is faulty, causing the 'Longteng' device to not work properly. We need you to fix it."

He Yudong carefully observed the part and was secretly surprised. The structure of this part was extremely complicated, and even a fifth-level fitter like him found it a bit difficult to work with.

"This part... is a bit difficult." He Yudong said.

"I know, that's why I asked you to come." Li Weiguo patted He Yudong on the shoulder, "I believe you can complete the task!"

He Yudong took a deep breath. He knew that this was a huge challenge, but also an opportunity to prove himself!

He took out the tools from the toolbox and began to repair it seriously.

As time passed, more and more beads of sweat appeared on He Yudong's forehead.

Just when he was about to give up, the system's voice suddenly sounded: "Ding! It is detected that the host is performing a difficult operation, triggering a special task - repair the 'Dragon Soar' device! Task rewards: an advanced fitter skill book and a mysterious gift bag!"
