After sending Sima Junan away, Hao Yun came to the top-secret base attached to the small 001 - the underground factory.

"Do you have any building materials, I want to expand the school!" Hao Yun said to Hao Ling'er very unceremoniously, in terms of seniority, Hao Yun is Hao Ling'er's ancestor who doesn't know how many generations ago!

Hao Ling'er swiped in front of her with her hand, and suddenly a list of various materials appeared in front of Hao Yun.

"These are metal alloys that have been re-refined from garbage, and these are new materials that have been recombined from inorganic waste, and if you want to buy elemental materials, they are also available, but they are a little more expensive. "Hao Ling'er, a businessman, is quite qualified, at least she has everything Hao Yun needs, after all, the underground factory is known as a universal factory that can produce everything.

"There's no need to buy quality, as long as it's economical and durable!" Hao Yun's requirements are not high, he doesn't want to build a golden building.

Hao Ling'er nodded: "Got it! I recommend you to use No. 003 instant powder, this material can be solidified into blocks after twenty-four hours after living into mud, it can be used instead of bricks, and can be processed into a variety of shapes with molds, which can perfectly meet any architectural requirements." After solidifying into a block, the material is delicate and shiny, and it can also produce the glaze of tired porcelain. When mixing mud, you can add a variety of pigments to the water, and after the mixture is solidified, it can be transformed into various colors. The material is extremely hard after solidification and has a nuclear resistance function - but when it is time to punch holes, you can use a special solution to dissolve the material out of the holes you want. ”

"Okay! That's it, the price?" Hao Yun asked.

"It's cheap, it's ridiculously cheap – it's made from recycled building materials, and there are a lot of old houses left after the old town has been rebuilt, and these houses have been demolished by me. The price of this material is only two cents per ton, which is very economical, and even if you build a skyscraper, it will not cost a few dollars. Hao Ling'er said truthfully.

"That's great!" Hao Yun slapped his face: "That's it!"

"Okay, this kind of thing is really worthless, so I'll give it to you for free this time, and you should help me clear my inventory! You must know that even if the underground space is large, there is a limit, and the garbage in a prefecture-level city is about to burst my inventory. Hao Ling'er said sullenly.

"Thank you so much! You keep playing, I'm leaving!" Hao Yun left overjoyed after getting the good news, he suddenly found that his school expansion project cost almost no penny - the materials were from Hao Ling'er, the labor was from the Terminator robot, and the design drawings were from Lu Ban. Attached to the small is fully capable of self-satisfaction!

When Hao Yun discovered this astonishing fact, he found that his funds can be used flexibly, before that, the group left a reserve of one billion yuan for the expansion of the school, but now the school expansion does not need to spend money, only need to leave 100 million for decoration and teaching equipment procurement.

This prospect is so good that Hao Yun is caught off guard, and happiness comes too suddenly, which means that no matter what project he does in the future, he won't have to spend a dime!

After having money, you must let money make money, and Jixian Education Group, which has an additional cash flow of 900 million, must continue to develop new businesses, no way, Hao Yun is a kind of tossing character, if there is no Sima Junan behind him, he would have gone bankrupt a long time ago.

After the students entered the school, the attached primary school regained its long-lost calm, and Hao Yun also returned to the life of the principal, and he is now getting together with Lu Ban to score the students' holiday practice.

The holiday practice of the attached primary school is their school-running feature, and it is also a necessary means for the all-round development of children's morality, intelligence, physical fitness, art and labor. Children can't stay in the ivory tower all the time without contact with society, and the necessary social practices can make children grow up healthily - if you walk in the attached primary school, you can clearly distinguish those who have been studying in the attached primary school for half a year, and those are the pink new students who have just entered the school.

The old students all have a temperament that has experienced wind and rain, and a holiday exercise has made them grow a lot.

Reading thousands of books, traveling thousands of miles, and reading countless people, these children have a lot of contact with people this holiday, whether they are serving dishes and washing dishes or setting up stalls as volunteers, they can't get out of touch with people. Their interpersonal skills are very strong, and they are definitely not comparable to those freshmen.

However, there are also good and bad social practices, and the school needs to score each person according to their performance, and the detailed rules for scoring are formulated by Lu Ban, because only his powerful processor can process so many children's video materials and point out their strengths and weaknesses - Hao Yun is just having fun here.

After analyzing the children's video materials, Luban will score them according to the children's performance and summarize a perfect written summary, in which Luban points out the children's strengths and weaknesses, as well as the direction they need to pay attention to in their future development.

These materials are sorted out by Lu Ban according to the basic principles of psychology, which are of great benefit to children, and the domineering of super intelligent robots can be seen, it can be said that Lu Ban is an indispensable golden finger of Hao Yun, if there is no Lu Ban, Hao Yun will not be able to summarize so many valuable things in a targeted manner.

The grading of holiday practice is: A, B, C, D four levels, with a score of more than 90 points for A, 80 points or more for B, 70 points or more for D, and 60 points or more for D, and there are no children who fail - because as long as they go to society, they are successful.

The children of the attached primary school did not secretly hide at home to avoid social practice, because Principal Hao had already made it clear: not participating in social practice means automatically dropping out of the attached primary school! This is a compulsory social activity!

Most of the children in the attached primary school were rated B or above, except for a few children who cheated and slipped with a C, and everyone's grades were very good. Lu Ban's evaluation is very fair, and the robot will not give emotional points!

After the score is obtained, the school's intelligent center will send everyone's holiday report card to everyone's smart terminal, and each child with the child has a wrist-type smart terminal, which has a cool shape, very powerful, and the processor is more powerful than the most advanced supercomputers of our time, and its display is a virtual projection, which is particularly stylish!

This kind of teaching aid has made countless primary and secondary school students in the seven cities envious, and the students of the attached primary school have also become the legendary "children of other people's families".

"I'm ninety-three!

"I'm ninety-five, please kneel!"

"Ninety-six laughs and doesn't say anything!"

"Seventy-three points for comfort!"

"How many points does Li Yunfei have?"

"I don't know... Zhao Xiaomeng, do you know?"

"Ninety-nine..."Zhao Xiaomeng said weakly after glancing at her best friend's smart terminal display.

"Oh my God, why is her score so high?" the crowd asked in surprise.

"You have filmed three TV series and two reality shows in one holiday, and your score will be so high..."Zhao Xiaomeng said quietly.

All:......
