When the voice of the crowd weakened, Gao Buer held a loudspeaker and shouted: "Everyone sees the propaganda poster of our college, you should know something about our college, we are definitely a dream home for poor students, a paradise for smart people to display their talents, come to us, do not ask about the background, do not ask about the past, only talk about learning, as long as you think you are a smart person, you can come!" ”

"Roar, roar!! I want to join! I want to join! ”

Looking at the excited crowd, Gao Buji smiled and pressed his hands, signaling everyone to be quiet.

"I know that some of you have come to study, some have come to see the excitement, and some are not convinced to want to find out, so not much to say, in order to show the demeanor of our Royal Qingbei College, but also to let everyone have a more intuitive understanding of the new learning, and in order to make everyone feel worthwhile, we have entered today's climax, the new learning show! Raise your hands and let our students take the stage with the first display board with a round of applause and roaring cheers! ”

Amid the cheers of the crowd, four students pushed a movable blackboard covered with cloth, one foot long, two meters long, and three meters high, and then the students pushed out the movable herringbone ladder. It was the first time for many people to see such a clever design, and they unconsciously craned their necks to look at it, and some even stood up.

Gao Buer quickly climbed the ladder, took the whip handed over by the student in his hand, and said loudly: "I have walked all over the streets and alleys of Chang'an, Luoyang, Yangzhou, Hangzhou and other cities, and found that everyone is using words to record and keep accounts, and the account books are often lengthy, and I Qingbei College has created 10 symbols such as 0, 1, 2...... 8, 9 and so on according to the meaning of the text, as long as you use these ten symbols, you can record endless accounts, such as the simplest 1 plus 9 equals 10, see, this is a number symbol can be infinitely combined." , simple and clear does not take up space. ”

As soon as the Arabic numeral symbols came out, the illiterate continued to be confused, and those scholars, students, children of official eunuchs, and businessmen who were mixed in the crowd immediately showed their eyes and quickly copied them, but there were not many people who were really prepared.

How could Xu Jingzong give up such a good opportunity to make money? I have long asked students to set up stalls to sell pen, ink, paper and inkstones, and the price is directly 20 times the market price.

Gao Buer gave Xu Jingzong a thumbs up, why didn't he expect such a good way to make money, it seems that he is not treacherous enough, and he is still far from being a qualified profiteer.

Gao Buer didn't care whether the crowd remembered it or not, and asked the students to turn over the blackboard, which was written on it with a big word "one by one, one by two, two by two, seeing that the crowd did not understand, Gao Buer immediately said: "This contains these two sets of formulas, which can allow us to break away from the abacus for oral calculations, but the beauty can only be granted to the students of our college, please forgive me." ”

Waving his hand to let the students remove the props, the crowd scolded, scolding constantly, what Gao Fuji wants is this effect, that is, to build a vague shadow in people's hearts, after all, the more you want to catch it but can't catch it, but you will want to catch it more, then you have to come to Qingbei College.

Gao Buer looked at the crowd with different expressions, was very satisfied, and said loudly: "Let's go to the second show, jump from the air and don't die, this involves another science, in order to save time, I arranged for students to complete this work, please look behind!" ”

Behind the crowd, I don't know when there was a wooden platform tens of meters higher, and a student on it was preparing something, and the crowd panicked when they saw that the student was about to jump down. The second item to show is the parachute of the later generations.

The student on the high platform jumped down, jumped down, and opened a semi-circular thing behind him at the same time, and when the semi-circular ball was all unfolded, the speed of the student's fall slowed down, and when he landed safely, the crowd was still surprised, and the student indifferently retracted the parachute with the help of his classmates, pushed the high platform to evacuate, and the crowd reacted.

Without giving them much time to think, Gao Buer continued: "Let's go to the third show, the scholar pulls out a thousand pounds!" ”

Saying that, he motioned for the students who had been preparing to appear on the side, this time it was a simple tower crane, to put it bluntly, it was a pulley group, and one end of the hook hung a stone of two or three hundred catties on the ground, and a thin student came over and pulled the rope head that stretched out, and it was easy to pull the stone off the ground.

Gao Buer saw the disdain of the crowd and said with a smile: "I know that everyone must be thinking that this is a trust, and they also suspect that this stone is fake, this is okay, I will let people put this device on the sidelines, everyone can go and verify it." ”

Gao Fuji waved his hand and asked the students to put the tower crane on the sidelines, and a group of people immediately went to verify it. Gao Fuji raised the horn and said: "I am not here to show off, but to tell everyone the importance of tools and instruments, which is also one of the knowledge taught and researched by our college." ”

Ignoring the restless crowd, Gao continued, "Now I'm going to show you the last item, which is called Blossom on a Metal Plate. ”

The student carried up a half-meter-square piece of silver metal, and Gao Fuji poured a bowl of silver-white liquid into the groove in the middle, and soon a stout flower-like and tree-like thing slowly grew on the metal plate, and the crowd shouted.

Gao Fuji took the opportunity to say: "This is the charm of another discipline called chemistry, do you want to unveil its mystery?" Welcome to Qingbei University! ”

After that, he didn't let the students move the props, so he retired and left quickly, leaving a commotion behind him.
