After the lunch class, Song Chu contacted the friend introduced by Gu’s father.

The other party sent a construction team over. Song Chu took them to the back mountain and then handed the design drawings he had drawn to the team leader.

The captain has always been in the construction industry. He took a close look at the design drawings and found that although he had never built anything like this before, his company could build it.

After communicating with each other and agreeing on the price, we signed two copies of the contract, and with the school's approval, we can start work tomorrow.

When the work started, Song Chu would take time to check it out every day and point out any problems immediately.

In the second week, Song Chu brought a simple cooling fan back to school.

It takes time to make an air conditioner. Gu Yue was afraid that it would be too hot for Song Chu to stay in school or do experiments, so he spent more than a week and made a cooling fan.

Today's fans rotate and use wind from all around to cool down the room, but the weather is too hot and the wind is also hot, so the effect of electric fans is not very good.

Gu Yue added a new type of cooler to the fan. The air it blows out is about the same as when the air conditioner is set to cold air at around 18 degrees, and it has low power and does not consume much electricity.

If Song Chu wants to use it in the dormitory or laboratory, he has to inform the principal first, after all, it requires electricity.

So she went to the principal's office first, holding the fan.

Principal Zhu and Vice Principal Ding were talking about something and were surprised to hear Song Chu knocking on the door.

He immediately said with a smile on his face: "Xiao Song is here, come in quickly."

Song Chu walked in and sat down, "Principal Zhu, I came here because I have something to discuss with you."

Principal Zhu asked with a smile, "What's the matter?"

Song Chu put the desktop fan on the table. "The weather is too hot now. My partner has developed a small cooling fan, so I want to use it in the dormitory and laboratory. I want to ask you if it's okay."

Principal Zhu and the others naturally knew who her partner was, and they all looked at the fan on the table.

"Cooling fan? Does that mean it's different from a normal fan?"

Song Chu nodded: "It's different. The wind it blows out has been refrigerated, so it will be very cool."

Principal Zhu and the others immediately showed their curiosity, "Can we try it?"

Song Chu smiled and said, "Of course."

Principal Zhu turned on the electric fan himself. Soon the fan started turning, and gusts of cool breeze blew out, making the stuffy office much more comfortable.

"The wind is so cool, and it's really different from an ordinary fan." Principal Zhu came over and looked left and right, unable to let go.

There was also an electric fan in his office at this time, but the wind it blew out was hot, only slightly better than having no air.

But this electric fan is different. It blows out completely cold air, which is very comfortable.

"Xiao Song, does this cooling fan consume a lot of electricity?" he asked.

Song Chu replied truthfully: "My partner deliberately reduced the power, and it consumes about one kilowatt-hour of electricity in about five hours."

“That’s not very energy-intensive.”

Now the country has air conditioners purchased from abroad. Principal Zhu saw it once some time ago and tried it out. It is indeed very cool, but the power consumption is terrifying, almost one kilowatt-hour of electricity per hour.

Plus, air conditioners are very expensive, so their school really can’t afford them.

But the cooling fan brought by Song Chu made them excited. It is necessary to put one in the laboratory.

They were worried about this, but they didn't expect Song Chu to bring the solution to their door.

"Xiao Song, does your boyfriend sell this cooling fan?" Although Principal Zhu knew that the grandson of the Gu family would definitely not be short of money, he still couldn't help but ask.

"A few days ago, a professor here fainted from heat stroke during an experiment. Our school simply cannot afford to buy an air conditioner imported from abroad to put one in each laboratory, and the electricity bill is also very expensive."

"So if your partner can sell it, our school would like to buy a few of these cooling fans and place them in each laboratory for everyone to use." He added with a sigh.

As for their office, he didn't even dare to consider it, fearing it would be too expensive.

Song Chu had never thought of selling this thing before, but after hearing what they said, he suddenly had an idea.

"I need to ask him about this first. Can I get back to you later?"

Principal Zhu smiled and nodded: "Okay, thank you for your help."

"You are welcome to use this cooling fan, whether in the dormitory or the lab. Our school will pay for the electricity. After all, we said we would give you a separate lab, but you didn't want it, so let's consider this as a compensation benefit."

He had heard many people say that Song Chu was a lucky star. He didn't agree with it before, but now he felt that she might really be one.

She can just happen to come and help solve the problems that have been bothering them these days.

Song Chu did not refuse. She originally wanted to say that she would pay for the electricity. "Okay, thank you, Principal Zhu."

After leaving the office, she did not return to the dormitory, but went to a more remote corner of the campus and then entered the space laboratory.

There is no surveillance now, so no one will notice that she disappeared out of thin air.

At this time, Gu Yue had just sent Song Chu back home and found that she had entered the space laboratory. He guessed that she might have something wrong, so he quickly went in as well.

"What happened?" Gu Yue asked.

Song Chu pointed at the electric fan he was holding with his eyes and said, "Our school wants to buy this."

Gu Yue was stunned for a moment, but soon realized what he meant. "I only made a few. If you want to buy, I will work overtime and bring people to make a few more."

If someone from the Agricultural University wanted to buy one, he definitely wouldn’t have the time and energy to help make a few, after all, he still has many new projects waiting to be worked on.

Moreover, he did not provide any to BGI, but only gave one to a few teachers' offices.

But if it is what Song Xiaochu wants, then he will work hard and overtime to do it.

Song Chu put down the electric fan and held his arm, "You don't have to work overtime. You are so tired, and I am the one who feels sorry for you."

Gu Xueshen doted on her so much, how could she bear to let him work so hard.

Gu Yue's heart warmed up, and he chuckled, "For you, I am willing to work harder."

"You don't need me to work overtime, but you came to tell me about this. You must still want to provide fans to the Agricultural University. Do you have a better idea?" He knew his partner quite well.

Song Chu nodded: "I think, how about letting my fourth brother do it?"

"Although he has invested in the club project, it won't be his main business in the future. I have always wanted my fourth brother to focus on a certain industry. Now because of this, I think electrical products are a good choice."

"You invest your technology and my fourth brother will open a factory to realize it. Not only will our technology lead the world, but it will also benefit the people," she added.
