This report also requires Qiao Shi to provide some parent-child certificates in the future, and the police on Zhao's mother's side will definitely investigate.

Qiao Shi's study was carried out in an orderly manner, and on weekends, he took Meng Nannan to Han Ban's house for dinner, and the police often came to inquire about the case.

Mother Zhao will definitely not admit that Qiao Shi is not in a hurry about this matter at the moment, on the contrary, Han Ban's son Han Minghui has recently returned.

Han Minghui studied sewage treatment technology at university.

Nowadays, the environmental pollution of the city where they live is relatively serious, and the water in some small rivers and waterways has already been confluent, and you can smell the stench from a distance, which is simply stinking.

Especially in the summer, some pedestrians pass by in a hurry and cover their noses.

There is also a river near No. 1 Middle School, and when the weather is hot in the summer, you can sometimes smell this bad smell in the classroom.

Now Han Minghui is preparing for his university graduation thesis, and he has no inspiration and can only come back for a few days.

Qiao Shi sorted out some information and went directly to Han Minghui.

Some time ago, Han Ban mentioned to her that this time the school was going to escort her to the first school, and Han Minghui was also a student of the first school, so Han Ban was also full of expectations on Qiao Shi.

Qiao Shi refused.

She doesn't need this place for guaranteed students, and the first school is not difficult for her, but she wants to make something before the college entrance examination......

"Brother Han."

This weekend, Han Ban and Shi Niang went to buy vegetables and meat, and Qiao Shi moved his computer to Han Minghui's room.

Han Minghui was preparing for his dissertation, and when he saw Qiao Shi come in, he chuckled and put down the work in his hand.

Perhaps because of the influence of Han Ban, Han Minghui always does not smile on his handsome face, he looks very mature, and his words and deeds are quite old-fashioned.

"What's the matter?"

For this elementary school girl, Han Minghui has no intention of underestimating it at all, he has seen that office software, even some professional students in the school may not be able to make it.

And now, Qiao Shi hasn't even taken the college entrance examination yet.

He had heard his father say that this software was all made by the little sister in her spare time, just to make it easier for his father.

"Brother Han, this is some information on sewage treatment that I have sorted out, you can see if it will help your paper."

"Oh?"

A flash of curiosity flashed in Han Minghui's eyes, pushed the black-framed eyes on his face, took the computer in Qiao Shi's hand and looked at it.

From the curiosity at the beginning to the excitement later, Han Minghui's hands trembled slightly.

"Senior sister, did you make this?"

In these materials, all aspects of sewage treatment are involved, and even a lot of professional knowledge is half-understood by him.

Many of these theories can even be written as professional papers and published in some foreign journals.

"Well, I checked a lot of information and did some experiments to sum it up."

"These are all good things, I really want to see what your head is made of, and you can come up with it."

Han Minghui was happy but worried.

The importance of these materials is self-evident, and if such a big horn is taken out, I am afraid that this achievement will be stolen by others.

"Senior sister, if you believe me? How about I go to the professor with these materials? I can guarantee that the first signature is you, but there may be a few more names to follow......"

That's what society is like now, just compare the names that come after? Others still value the first and second signatures.

"Brother Han? Is this your paper? I don't just want a thesis, I want to be a complete invention of this technology when I graduate from high school. ”

"Huh? Yours is the case. ”

Han Minghui gasped.

Is the country's sewage treatment technology still not perfect? Often, some large-scale sewage treatment plants have to be imported from country D.

However, the price of advanced processing equipment is high, and people rarely sell it, and all aspects of it are technology? If it's a little broken, you have to hire someone from country D to repair it at a high price.

The subsequent dimensional costs are equally terrifying.

Often some large factories buy second-hand equipment? Even so? If you don't have tens of millions, you can't get down.

If their country can really produce such technical equipment......

"So I'm going to make a lot of money during this time? Wait until the summer vacation to find a way to get some materials, come back and study first. ”

For Qiao Shi's terrifying talent? Han Minghui didn't doubt it? There are many celebrities in this world, what is not something from scratch, and if the hands-on ability is insufficient, it is more hands-on, which success is not summed up after countless failures.

After eating at noon, Qiao Shi assigned some homework for Meng Nannan to continue brushing the questions? Later, he discussed the problem of sewage treatment equipment with Han Minghui.

It's getting dark for a while? Han Minghui sent the two back home.

As soon as you get home? Meng Nannan was completely paralyzed.

"Master? I'm so hard today, I've been watched by Hanban all afternoon, woo woo woo ......"

She can't do math in the first place? Han Ban teaches mathematics again, and when he sees her doing problems, he always hates iron and steel.

God knows how broken she was.

"Okay, didn't you say that you want to come with me in the future, I'm going to the first school, what about you?"

Qiao Shi looked at Meng Nannan calmly, and Meng Nannan lowered his head in a huff.

She really wanted to go to the first school with her master, but she was a math ......

It's really scummy.

After making up classes during this time, it is estimated that there will be no problem with key universities, but the first university will definitely not be able to get in.

"Okay, I'll give you a guess when the time comes, your English and Chinese are no problem now, and there are still two months left, I will pull you up in math, come here."

Meng Nannan was lying on the sofa honestly, and Qiao Shi slowly massaged the acupoints on Meng Nannan's head.

?

There are less than two months to go before the college entrance examination, and the countdown on the blackboard will be reduced by one day every day that passes, but Qiao Shi went to participate in the National Mathematics Olympiad on behalf of the school.

After winning the first place, he was pulled to participate in the chemistry competition......

If it weren't for the upcoming college entrance examination and being stopped by the Han class, I'm afraid that the teachers of many subjects would plan to pull people.

Especially during this period, the grades of the entire class have increased significantly, which makes many class teachers of other classes envious and jealous.

For Mao Zhao Baolai is not their class......

Time flashed to May, and Qiao Shi finally drew a good luck charm in this world.

After putting it on Meng Nannan, although she can't improve her grades too much, most of the minor mistakes or careless mistakes can be corrected.

The results of the last mock exam were infinitely close to the admission score of the first university last year, and Meng Nannan almost jumped up excitedly.

The police finally made some progress and found the hospital back then.

It's just that so much time has passed, and there is very little useful evidence.

Qiao Shi was not in a hurry, and privately continued to cooperate with the CEO of Chonghuo Company to continue to strengthen the loopholes of the firewall for him.
