The Red Era, the Opening University Speech

Chapter 25 Li, will you envy me too?
Li Mu smiled and said, "Then you should know that this kind of machine is actually extremely dependent on manual operation."

"Yes, I have seen the teacher operate it before. If you are not careful, the wafer will crack and the groove edges will break." Wang Ya recalled.

Li Mu then frowned, pretending to have a sudden idea, and said, "Do you think it is possible for us to build a machine and develop production equipment ourselves?"

"How is this possible?" Wang Ya was so shocked that all her sleepiness disappeared!

Li Mu quickly comforted him: "Don't worry, this is just my personal opinion"

"Tell me in detail!" Wang Ya's sleepiness was much relieved now.

"Look, I have an idea to make a grinding wheel dicing machine to solve these two problems. What do you think?"

"Grinding wheel?" Wang Ya thought about it and felt a little confused.

Using a grinding wheel for cutting will probably not produce good results as the hardness is not enough.

"Yes, that's the grinding wheel."

“I am studying how to combine diamond and grinding wheels to achieve improvements in wafer cutting.”

"Is this... feasible?" Wang Ya hesitated.

Diamonds and grinding wheels, no one has ever proposed this method.

In the past, everyone used diamond dicing machines. Although the failure rate was high, the loss would be greatly reduced as experience was gained.

How come when it comes to Li Mu, he suddenly wants to make a machine?
Seeing that Wang Ya had forgotten about asking him to go to the professor's place, Li Mu added fuel to the fire:

"Yes, that's what I think. Grind the diamond into powder and attach it to the grinding wheel. Fill the gaps between the sand grains with metal, and you can reduce the damage to the wafer."

"It can also improve the quality of finished wafers. Do you think this method is feasible?"

Li Mu finally threw the question to Wang Ya.

Wang Ya was already feeling a little drowsy, and now she felt even more dizzy after hearing this.

"In fact, there is another alternative method. You can use resin and metal binder to make a grinding wheel dicing machine. Although there will be pores, the process will be much simpler..." Li Mu said as he did the space walk.

Wang Ya was unaware of anything. She lowered her head, frowned, and walked forward while thinking.

Li Mu breathed a sigh of relief:

"Finally got rid of it!"

"But I can't relax yet. My foundation is not solid enough. I fooled Wang Ya this time, but what about next time?"

"If Professor Huang comes to our house, there will be no chance of recovery."

Seeing Wang Ya's figure gradually going away, Li Mu thought for a moment, turned around and ran towards the cafeteria.

The cafeteria was packed with students.

Li Mu handed in his meal ticket, got his food, put it in an aluminum lunch box and put it in his bag. He then quickly walked out of the cafeteria and went to the class teacher's office to ask for leave.

The class teacher did not suspect at all that Li Mu, who had excellent grades, might be lying, and directly approved the leave application.

……

After half an hour.

When they returned to the compound, Aunt Zhang was hanging clothes in the front yard. Seeing Li Mu, she greeted him, "You're back so early today. Have you had lunch? If not, come and have something to eat at my house!"

"I ate it, thank you, Aunt Zhang." Li Mu responded.

Continuing to walk inside, under the pear tree in the corner of the yard, two little girls, Li Lan and Li Yu, were squatting on the ground, counting ants intently.

Maybe it was because they heard the footsteps, but the two little girls raised their heads and found Li Mu.

"Brother~You're back~"

The two sisters excitedly jumped to Li Mu's side, raised their heads and called out sweetly.

After spending a long time together, Li Mu also liked these two sisters very much. He smiled and rubbed the hair of the two little ones.

Grandma Li, who was mending clothes at home, heard the sound and came out without putting down the needlework in her hands.

Grandma Li asked, "Xiao Mu, why did you come back so early today? Aren't you going to class?"

"I asked for leave and came back to get some things." Li Mu said casually. "Are you going back this afternoon?" Grandma Li had no doubts. She had never worried about her eldest grandson's studies since he was a child.

"I won't go back today." Li Mu replied casually.

"Okay, grandma will make you something delicious today." Hearing this, Grandma Li put her needle and thread aside and walked into the kitchen with a smile.

After eating at home, Li Mu locked himself in the room and continued to study hard.

Only when his neck ached did Li Mu raise his head and collapse on the bed.

"Not only do we not have a computer or a cell phone, we don't even have a TV... When will this end?" Li Mu sighed.

After lying down for a while, Li Mu sent a message to Ask to complain:
"Asker, my friend is almost giving up on studying. Aren't you a researcher? How did you manage to keep studying?"

Ask: "Actually, I also find it difficult. I graduated from Yelu Doctoral School at the age of 22 and entered the research institute, but I haven't achieved any decent results so far. It's really easy to give up studying and doing research!"

"Like me, I don't expect to achieve much now, the game is still fun!"

Li Mu wanted to comfort Ask, but when he saw that Yelu had graduated with a Ph.D. at the age of 22, his mouth twitched: "Fuck, no more fun, let's go!"

"So I envy you, Li. You have such a rich life!" Ask continued.

Li Mu rolled his eyes and said, "What kind of Versailles statement is this? You graduated with a PhD at the age of 22. How many people envy you!"

Ask didn't expect that he actually had something to be envied, and asked expectantly: "So, Li, do you envy me too?"

Li Mu pretended to be nice: "Not really, because being a playboy is really fun."

Ask: "..."

The chat ended unilaterally.

Li Mu got up from the bed and planned to take a walk in the yard.

As soon as he opened the door, the evening breeze blowing in his face refreshed Li Mu.

Looking at the yard again, it was time to get off work. Men and women in workers' uniforms were coming and going, greeting each other.

Aunt Li Mu came back from get off work and found Li Lan and Li Yu running wildly with several other children in the yard. She shouted, "Slow down! Don't fall!"

Seeing Li Mu coming out, the aunt said again: "Xiao Mu, wait a moment, I will go to cook right away."

"Auntie, don't worry, I'm not hungry yet." Li Mu responded with a smile.

After wandering around for a while, Li Mu returned to the house.

Just as I sat down on the chair, I heard a familiar voice outside the door:
"Li Mu, good news, good news!"

"Li Mu, we are here to tell you the good news!"

Zhang Kai's voice was so loud that Li Mu could hear it from dozens of meters away.

"What good news? You look so happy." Li Mu stood up and was about to open the door when Zhang Kai pushed the door open and walked in.

Before he could say anything, Zhang Kai couldn't help but give Li Mu a big hug.

"What's going on?" Li Mu was strangled to the point of being unable to breathe.

"First, we are first!" Li Jian spoke first, his face flushed with excitement, and his skinny body trembled slightly with excitement.

Li Mu: “What?”

Zhang Kai's voice was a little trembling as he answered quickly: "In the Mechanical Design Competition, we won first place in the team competition!"

Li Mu was caught off guard when he heard the news.

Although I had been mentally prepared to win the award, taking first place and gaining greater fame meant I was one step closer to being exposed as a poor student before I had finished catching up on my engineering knowledge from high school and college.

"What's wrong? Are you silly because of happiness?" Zhang Kai smiled and gently hit Li Mu's shoulder.

Li Mu forced a smile: "Yes! I also want to congratulate you, you have worked so hard for so long, first place is the honor you deserve!"

The smiles on their faces were almost reaching their ears.
