Yan Hao treated He Shao to a big meal. After the meal, the two did not rush back to school, but went to a nearby shopping mall. It was a rare opportunity for Yan Hao to go out, so he wanted to buy some useful mecha parts to study.

"Classmate, what parts do you want to buy?" The clerk was a pretty lady. When she saw Yan Hao coming in, she greeted him warmly. She had some impression of this fair-skinned boy. She knew that he was a freshman in the Mecha Manufacturing Department of the Federal University and often came to their store to buy things after school started.

"I want to buy parts for the mecha arm." Yan Hao replied.

"Which part do you want?" the clerk asked.

"I want them all." Yan Hao said.

"If you want both, the prices are not cheap," the clerk reminded.

"It's okay, beautiful sister. Our Hao is a rich man now and has no shortage of money." He Shao said with a smile.

"Now you have money? Okay, come with me." The beautiful salesperson was amused by He Shao and took the two of them to the spare parts area in the store.

Yan Hao blushed at He Shao's words "rich man embarrassed" and complained quietly, "Why do you make me sound like a nouveau riche who came here to show off his wealth?"

"You are a nouveau riche." He just randomly developed a formula model and then made a fortune.

Yan Hao rolled his eyes at him in displeasure, walked a few steps faster, passed He Shao, and followed the beautiful clerk. After a while, the three of them arrived at the parts area. Although it was only a corner of the mecha store, the area of ​​the parts area was not small, almost twice the size of the classroom where they had classes, and it was filled with various parts.

"The mecha arm parts are in this area." The beautiful salesperson pointed to one place and said.

"Beautiful sister, if we buy all the parts, can we go back and assemble a mecha arm by ourselves?" He Shao asked.

"That's true in theory, but the parts we sell here are only used for mecha replacements. Some of the circuits inside the mecha arm are not taken into account. If you want to assemble a new mecha arm with the parts yourself, you must solve the circuit problem yourself. Do you already know how to design your own circuits?" asked the beautiful salesperson.

He Shao naturally didn't know how to design a route. Seeing the beautiful sister looking at him, he had to shift the blame and look at Yan Hao.

"..." Yan Hao was speechless for a moment, but still answered, "We don't know how to do it yet, so we want to buy some parts to practice."

"So it's for practice. Then I suggest you buy mecha parts below level three. Beginners basically start with mechas below level three." The beautiful salesperson was so delighted by the two people calling her "sister" that she couldn't help but give more suggestions.

"Sister, I want to buy parts for the fourth-level mecha." Yan Hao said.

"Level four, level four is over here." Although the beautiful salesperson felt that mecha parts below level three were more suitable for Yan Hao, she still had to comply with customer demands in the end.

The beautiful salesperson then took them to the area of ​​level 4 mecha parts. After another round of introduction, Yan Hao chose a complete set of the latest arm parts.

"There are 236 main parts in total, and the total cost is... 86,360,000 star coins." The beautiful salesperson announced the total price.

"More than 86 million?" Yan Hao was stunned.

"Classmate, you look so well-behaved, but I didn't expect you to bargain. Okay, since you are so cute, I will waive the balance of 360,000 for you." The beautiful salesperson said with a smile.

Yan Hao waved his hands repeatedly, a little embarrassed, "I'm not trying to bargain, I just don't have enough money."

The beautiful saleslady was stunned. Didn’t she just say he was a rich man?

"Why don't you just buy the arm parts for a level-three mecha? Thirty million will be enough for a set," suggested the beautiful salesperson.

"No, I want to buy the level 4 one." Yan Hao refused.

"How much money do you still need?" He Shao didn't expect that a complete set of mecha arm parts would cost 80 million.

"I only have 53.61 million." Yan Hao whispered.

"That's still more than 30 million short." He Shao frowned, "I only have a few million on me, which is pocket money my mom secretly gave me. It's not enough. How about we buy it next time when we have enough money?"

Yan Hao touched the parts that were already piled up in front of him, feeling reluctant to part with them. He had already designed the circuit diagram in his mind, and was just waiting to go back and try to assemble it, but he didn't expect that he would not have enough money. He was really reluctant to part with them, looking at the parts reluctantly, and then looking at the beautiful clerk hesitantly.

The beautiful saleswoman's heart softened when she saw the young man's pitiful eyes: "How about this, you buy a part today, and I'll give you a discount price for a complete set of arm parts. You can come back to buy the rest when you have money."

"Beautiful sister, can we pay in installments? We can pay a part first, take the things, and then pay the balance in installments." He Shao negotiated.

When Yan Hao heard this, his eyes lit up.

"Don't look at me like that." The beautiful saleswoman said helplessly, "We have a rule in our store that you must be a level 3 mecha maker to buy on credit. You are freshmen, so you can't buy on credit yet."

"Beautiful sister, please be flexible." He Shao called her sister in a sweet voice and signaled Yan Hao with his eyes to join in.

"Sister." Yan Hao understood and walked forward with gritted teeth.

"Hmm?" The beautiful salesgirl looked at Yan Hao.

"You are very beautiful." The tone was hard and one could tell that it was said deliberately in order to get credit.

“……”Beautiful shop assistant.

“……”He Shao.

It's over. Maybe there was still a chance just now, but now it's probably completely gone. Hao, can you please have some soul when you praise others?

“Can I pay in installments?”

He Shao suddenly wanted to die, and was so embarrassed that he wished he could find a hole in the ground to crawl into.

Hao, even if you are a genius, I regret meeting you at this moment. It's ok for you to praise someone for being soulless, but you even directly stated your purpose?

"Puff..." Just when He Shao was about to suffocate, a burst of laughter broke the awkwardness. The three turned their heads and saw an old man with half-hundred-year-old hair standing not far behind them.

"Professor Qin?!" Yan Hao and He Shao spoke at the same time.

Professor Qin coughed twice to ease his laughter, then walked over and said, "Come to buy something."

"Yeah." Yan Hao nodded.

"Not enough money?"

"Yeah." Yan Hao nodded.

Professor Qin turned to the beautiful clerk and said, "I am a level 7 mecha maker. If I guarantee you, can your store arrange installment payment for my student?"

"Are you a level seven mecha maker?" The beautiful salesperson looked at Professor Qin in shock, her eyes full of admiration.

"Is it okay?" Professor Qin nodded with a smile.

"Yes, of course." The beautiful clerk nodded quickly.

He is a level seven mecha maker. With only 80 million, he can just make a part and sell it for this price. How could such a person possibly default on his debt?

Finally, with the guarantee of Professor Qin, Yan Hao paid a down payment of 30 million, and the remaining installments could be repaid within one year.

"Thank you, Professor Qin." After leaving the mecha shop, Yan Hao thanked Professor Qin gratefully.

Professor Qin waved his hand and asked, "You bought the Level 4 mecha parts, do you want to try to assemble them yourself?"

"Yeah." Yan Hao nodded.

"Can you design the Level 4 circuit diagram?" Professor Qin asked about designing, not memorizing. For ordinary freshmen, as long as they can remember the circuit diagram of the mecha, they have completed the task, but Yan Hao's talent is different. Professor Qin believes that the knowledge he has mastered has already surpassed the freshman courses.

"I don't know how yet, I just want to buy it and try it out." Before successfully assembling it, Yan Hao would not tell others that he could design a circuit diagram.

"You dare to come and buy parts before you even learn how to do it. It's not cheap."

"I just think that I would learn faster if I had the real thing. Teacher, I will pay attention next time." Yan Hao whispered.

"Why should we pay attention? That's the way it should be." Professor Qin laughed. "Mecha research is very expensive, but this is only in the early stages. Once you get started, money won't be a problem. If you have an idea, you must dare to try it, otherwise how can you make progress? Every mecha maker is made with money. Otherwise, why would we teach you how to make energy blocks in the first class? It's to make you make money."

It turns out that the professor was not blaming himself, but affirming himself.

Yan Hao, who understood, blushed with excitement and nodded heavily.

Professor Qin smiled and patted Yan Hao on the shoulder, his eyes fell on He Shao again: "He Shao, how is your level 5 energy source block training going?"

"It's still a little short." He Shao said with a bitter face, "Professor, can you lower the requirement a bit? Instead of 75%, how about 73%?"

"It seems that your current best score is 73%. Not bad, you have made progress. You are only two percentage points away. Keep up the good work." Professor Qin said, smiling and patting He Shao on the shoulder.

"Yes, professor." He Shao responded weakly.

"Then professor, let's go back to school." Yan Hao said.

Professor Qin nodded and was about to wave them off when he suddenly thought of something. He looked at Yan Hao and said, "There is an intelligent machine store on the second floor. You can stop by and take a look."

"Okay." Although Yan Hao didn't understand why, he still nodded and agreed.

"Let's go." After saying that, Professor Qin turned around and went back to the mecha shop.

Yan Hao and He Shao took the elevator to the second floor.

"Why does Professor Qin ask us to go to the smart machine store?" He Shao asked puzzledly on the way.

"Go and take a look and you'll find out." Yan Hao said.

The two walked around the second floor for five minutes and then found the smart machine store that Professor Qin mentioned.

The Smart Machine Store, as the name suggests, sells smart robots. As soon as the two entered, they saw robots of various sizes and varieties.

"What would you like to buy?" A uniformed staff member came over.

"This is our first time here. Can you introduce it to us?" He Shao said.

"Of course. Let me first introduce the latest model of robot in our store." The staff took the two to a robot about 70 to 80 centimeters tall and introduced it, "This is the latest intelligent household robot developed by our company. We have fully upgraded its system and added a mimicry sensing system on the original basis."

"Mimetic induction?!" Yan Hao, who had been silent all this time, suddenly widened his eyes when he heard the word "mimetic induction". He looked at the unprepossessing little robot in front of him in shock.

"A robot equipped with a mimicry sensing system can record and simulate all the movements of its owner, including dancing, running, and even fighting..."

"Can I try it?" Yan Hao listened to the other party's introduction before asking.

"Of course." The staff walked over and operated the robot for a while, then said to Yan Hao, "The mimicry sensing system has been activated, locking you as the first target. From now on, all the actions you do will be perfectly simulated."

Yan Hao turned his head to look at the robot, and as he moved, the robot also turned its head. Yan Hao's eyes lit up, and he couldn't help but take a step forward, and the robot also took a step forward.

In the next minute, Yan Hao tried to make various movements, and the small robot standing opposite him was like his mirror image, perfectly simulating all his movements. The only flaw was that compared to Yan Hao's smooth movements, the robot's movements were obviously much slower.

"Sure enough, the reaction is a bit slow." Yan Hao murmured.

"The mimicry reaction speed of our robot is already very fast. It can respond within one second after reading your movements," said the staff.

Yan Hao didn't say anything, but suddenly raised his hand, spread his five fingers, and began to move flexibly. The robot opposite also raised its hand, and then the mechanical fingers moved, as if trying to make the same movement, but ultimately failed.

"It seems... I'm still not able to perform delicate operations." Yan Hao continued to mutter to himself.

"Although it cannot perform particularly delicate operations, it can still do some simple movements, such as shaking hands, clenching fists..." the staff explained diligently.

He Shao couldn't stand it anymore, patted the staff member on the shoulder, and interrupted: "Don't pay attention to him, he can't hear you."

"Ah?" The staff was stunned.

"Leave him alone for a while. Come on, let's go over there and tell me something else."

So the staff took He Shao around other parts of the store. About half an hour later, Yan Hao chased after him holding the robot and said, "He Shao, He Shao, I want to buy this. I've seen the price. It's only eight million. I can afford it."

"Handsome guy, let's buy this." He Shao immediately said to the staff beside him.

“……”Staff.

It seems like I just wasted the last half hour talking.

The author has something to say: He Shao: How come you can’t even praise others?

Yan Hao: I praised you.

He Shao: ...
