In the laboratory, the babe yawned violently. He hadn't had a good night's sleep for a week. At this moment, any yawn could make him secrete sleepy tears.

What was wrong with my brain that I chose to study mecha manufacturing?

Every time at this time, the Babi worm would let out a cry from the soul.

Babi Chong sighed, rubbed his dry and stinging eyes, and was about to go outside to drink some water. At this moment, he caught a glimpse of a prompt message on the optical computer terminal on his left wrist.

Is someone looking for me?

Babi Chong clicked on it and found that it was sent by Yan Hao, and it was sent three or four hours ago. Babi Chong would shield the signal of his optical computer when doing experiments. If it was not someone in the institute who wanted to contact him, outsiders would not be able to get in touch with him.

"Did you encounter any problems?" Although Babi Chong was very tired, he thought that Yan Hao had just arrived at the research institute and was only slightly familiar with him, so he forced himself to open the button to see if Yan Hao had encountered any trouble.

Then……

"Ah!!! Ahhhhhhhhh~~~" - a scream that pierced through the roof and directly scared the other four people in the laboratory.

Four men with disheveled hair and red eyes turned their heads to look at the Barbie bug, then looked at each other in confusion.

"Sixth Junior Brother, can't bear it anymore and has collapsed?"

"Not really. It's only been seven days."

A young man whose workbench was right next to the babi worm walked over with a worried look on his face: "Brother, are you too tired?"

The Babius glanced at the young man, then hugged his shoulders, and its screams suddenly turned into hahaha laughter, which sounded like a madman's laughter.

“This is crazy.”

"Xiao Qi, take Xiao Liu back to the dormitory." The third senior brother frowned and said to the young man.

The young man nodded and was about to take the worm away, but the worm broke free and said, "What are you doing? Let me go. I'm not crazy."

"Brother, what happened to you just now? Why did you suddenly shout?" The young man's name was Ruan Bowen. He was the youngest disciple in the research institute before Yan Hao became Master Zhong's apprentice, and he was also Yan Hao's seventh senior brother.

"I, hehe~~~" The Babe couldn't help laughing again.

Everyone looked at each other, and the same signal flashed in their eyes: Babi is crazy, send him to the hospital.

The third senior brother nodded towards Ruan Bowen. Ruan Bowen understood and grabbed the giggling Babi bug and tried to drag it out the door.

"Hey, what are you doing? I told you I'm not crazy." The Barbie worm tried to break free, but this time Ruan Bowen increased his strength, and the Barbie worm couldn't break free for a while.

"I'm really not crazy, let me go." Babi Chong grabbed the door frame with both hands. Seeing that he was about to be sent to the hospital as a mental patient, he anxiously shouted to his third brother who was looking at him with a heartbroken face, "Third brother, I solved the formula."

These words were like thunder from a clear sky, and everyone looked at the Babi worm in surprise.

"No, I didn't untie it..."

The surprise faded, and at the same time, the cause of the madness of the Babesia was found.

"It was my junior fellow apprentice who solved it. The formula is in my optical computer terminal."

As soon as Babi Chong finished speaking, he felt that Ruan Bowen's force on him had weakened. He breathed a sigh of relief and was about to explain a few more words, but when he looked up, he saw three figures suddenly appear in front of him.

The third, fourth, and fifth brothers lined up in a row, staring at the optical computer terminal in his hand with eager eyes: "Where's the formula?"

Five minutes later.

The five people stared at the formula projected on the big screen, revering it as if it were a god.

"Savior."

The next day, Yan Hao got up as usual, washed up, and planned to go out for dinner. When he opened the door, he was frightened by the five figures standing at the door and took a step back.

"Senior~Brother?" - All five of his senior brothers came, and Yan Hao didn't know who to call first, "Why are you here?"

“Junior brother.” The third brother stared at Yan Hao with scorching eyes, took a step forward, and hugged Yan Hao in front of his astonished gaze, “We did it, ahahahaha…”

The other four people also smiled sincerely at this time and expressed their gratitude to Yan Hao.

"Junior brother, thanks to your formula, we have completed the modification of the third-generation system ahead of schedule."

"Junior brother, you are the savior."

"Thank you, Junior Brother."

"I've told you all, my junior brother is a math genius." Babi Chong - a proud look on his face.

"Why are you showing off? You didn't calculate the formula."

"You are not a genius either."

"But Junior Brother was the first one I met."

"What's wrong with you being the first one to know him? This junior brother is not your junior brother."

Yan Hao was hugged tightly by his third senior brother. He listened to the bickering between his senior brothers and vaguely understood what was going on. The last bit of uneasiness in his heart completely disappeared and turned into a warm current.

Brother Heng was right. People who like me can naturally feel my feelings. It seems that all my senior brothers like me.

Babi Chong and the others came here after they finished updating the third generation system. They were all very sleepy, but they wanted to thank Yan Hao in person, so they waited outside Yan Hao's door. After thanking him, they were exhausted and went back to the dormitory to sleep. They slept all day, and Yan Hao didn't see them again until noon the next day.

He was called over there.

"Junior brother." Yan Hao was greeted with five enthusiastic gazes as he entered the room. After a day of rest, the five people finally returned to their normal state.

Yan Hao smiled, then walked up to Master Zhong and called out respectfully, "Teacher, are you looking for me?"

When Mr. Zhong asked him to come over, he just said that he had something to do, but he didn't say what it was.

"I heard that you also participated in the modification of the third-generation system?" asked Mr. Zhong.

Yan Hao subconsciously turned his head to look at the senior brothers standing next to him. Did the senior brothers tell the teacher about this matter?

As if seeing Yan Hao's confusion, the third senior brother smiled and nodded at him.

"I just provided an idea to my senior brothers." Yan Hao finally replied.

"That's not just an idea. The calculation formula that Junior Brother provided us not only solved the problem of the arm system, but also increased the computing capacity of the entire system. The performance of the current third-generation system is at least 20 percentage points higher than we originally expected." The third brother said, "So teacher, please add Junior Brother's name as well."

Add a name, what name?

"They want to add you to the research and development list of the institute's third-generation system. What do you think?" Mr. Zhong asked Yan Hao.

Yan Hao was shocked: "No, I just helped calculate a formula, how can I be considered a R&D staff?"

The third-generation system was a project that the teacher and his seniors had been developing for several years. He just spent half a day calculating a formula. How could he sign his name on the same project as his seniors who had worked hard on the research for several years?

"But without you, we wouldn't have been able to complete the development of the third-generation system so quickly." said the third brother.

"It's just a matter of time. Even without me, you can solve it by spending more time." Yan Hao said.

"Your formula directly improves the performance of the third-generation system by 20%. It can be said that you have upgraded the third-generation system twice on your own. This is not something we can do in a short time." said the fifth brother.

"It's not just this formula. The math problem you helped me solve half a year ago was actually a bottleneck encountered by the third-generation system. So, by this calculation, you have actually started participating in the development of the third-generation system half a year ago." said the Babi Worm.

"right."

"That's right." The others echoed.

Yan Hao was not good at rejecting people. At this time, he was "besieged" by his fellow brothers. He could only look at Zhong Lao helplessly and made his last struggle: "Teacher."

"Since others have no objection, add your name as well."

"But..." Yan Hao still felt it was inappropriate.

"Although you only calculated two formulas and it took you less than a day, you completed half a year's work for them." As he spoke, Mr. Zhong glanced at the five people in the row with disdain.

“……” Senior brothers.

We are so useless!

"However, you are not officially involved in the research, so it is not appropriate to be considered a formal R&D staff member. I will give you a position as a R&D assistant and put you at the end of the list."

After Mr. Zhong said this, Yan Hao was in a difficult position to refuse. Anyone who assisted in research and development could be considered a research and development assistant. Yan Hao did help solve the two major problems encountered during the development of the third-generation system. Strictly speaking, he could indeed be considered a research and development assistant.

Although the brothers felt that the value Yan Hao brought to the third-generation system far exceeded that of a research and development assistant, and that it was a bit unfair for Yan Hao to be named a research and development assistant, they could not say anything more since Master Zhong had made the final decision, so the matter was settled. When the third-generation system was announced to the public, Yan Hao was listed on the list with the title of research and development assistant.

After the news of the completion of the development of the third-generation system was announced, the upgrade of the mecha system was put on the agenda.

In their spare time, the thing the seniors talk about most is system upgrades.

"Will Junior Brother go with us to upgrade the system this time?" Ruan Bowen asked.

"Of course he will. We have all left the institute, and the teacher will also leave. We can't leave my junior brother alone in the institute." said Babi Chong.

"Are you going to leave the institute?" Yan Hao asked.

"Yes, now that the third-generation system has been developed, the next step is to complete the system upgrade for the military's mechas and help them become familiar with the operation of the new system as quickly as possible." Babi Chong explained.

Yan Hao nodded.

"What do you think? Are the people from the three great families going to do everything they can to get the teacher to go to their place?"

"Of course, it's like this every year. However, the people from the three great families would never have guessed that every time the teacher chooses a place, he does it by drawing lots."

"Where did the teacher go during the last system upgrade?"

"It seems that I have drawn the lot to find the location of General Feng's base."

"Then I guess I'll choose one from the Sima family or the Sheng family this time."

Yan Hao listened to the analysis of his brothers and became more and more confused: "The systems are all the same, and they will be fully upgraded sooner or later, why do we have to fight for them?"

"It's not just a system problem. Who is our teacher? He's a level 10 mecha maker." The third brother explained to Yan Hao, "Although the teacher has a bad temper, he has great respect for the soldiers on the front line. He is usually busy doing research in the research institute, but as long as he goes to the army, the mecha makers in the army come to ask any questions they don't understand, and the teacher will help answer them. As students of the teacher, we may not think much of it, but for other mecha makers, it is a rare opportunity to receive guidance from the mecha master."

"The three great families each have their own factions, and they also have their own group of mecha builders. For this system upgrade, the teacher will divide us into three groups, one of which he will lead personally. Think about it, whichever station the teacher goes to, the mecha builders in that station will get this opportunity."

Yan Hao nodded in amazement. It turned out to be just a system upgrade, but there were so many twists and turns.

"Junior brother, you must be following the teacher's group, so which base do you prefer to go to?" Sixth senior brother Ruan Bowen asked curiously.

"Admiral Sheng's station."

Ruan Bowen just asked casually, but he didn't expect Yan Hao to answer so clearly. He couldn't help but become more curious: "Why?"

Yan Hao blushed, poking at the rice with his chopsticks: "My... boyfriend is there."

Yes, Sheng Heng went to the Sheng family’s residence to deliver the phantom potion to his elder brother.

“!!!” Senior brothers.

After a brief silence.

"How about taking the back door?" suggested Babi Chong.

Under Yan Hao's puzzled gaze, the brothers looked at each other and nodded in unison.

So on the second day, when Master Zhong asked his disciples to make paper balls for drawing lots, they naturally touched General Sheng's residence.

"Then let's go to the Sheng family's residence. Third brother, you and fifth brother go to the Feng family. Fourth brother and seventh brother go to the Sima family. Sixth brother, you and Yan Hao come with me." Old Master Zhong divided the work.

"yes."

Yan Hao looked up at the Barbie bug in a daze, only to see the Barbie bug wink at him playfully.

Yan Hao suddenly realized: So, it was this back door.

The author has something to say: Sheng Heng: Look at my wife, she has already made a great contribution to our family before she even entered the house.

All senior brothers: For the sake of my junior brother’s wife, it’s okay to use a back door.
