Originally, Xue Xiang thought that Han Du could make up for it by just a few thousand guan, but even if he wanted to buy this technology, it would only cost more than 10,000 guan at most.

If Han Du offered 10,000 yuan, Xue Xiang would definitely argue with Han Du.

But what he didn't expect was that Han Du asked for 100,000 guan! The deposit alone was 20,000 guan, which was far more than what he expected. How could he raise the price again?

If he continues to raise the price for 100,000 yuan, he himself, not to mention others, will not be able to overcome this hurdle.

In that case, I would be too greedy.

"Ahem, are you telling the truth?" Xue Xiang approached Han Du, stared into his eyes, waved his hand in front of Han Du's eyes, and asked doubtfully: "Are you not confused?"

Han Du smiled and blocked Xue Xiang's hand, and said with a serious face: "Of course, I am very sober now. No, the deposit is already here, what do you have to hesitate about?"

"Okay, I agree." Xue Xiang really couldn't see what the problem was, so he gritted his teeth and nodded.

"I agree too." Fang Xiaoru also agreed. .??.

Han Du immediately felt relieved, took out a piece of paper and said, "Then let's put the villain first and then the gentleman, and sign it in black and white."

Xue Xiang and Fang Xiaoru looked at each other, hesitated, and signed with their pens.

Han Du carefully dried the ink, folded it, put it in his arms, and patted it twice. He pushed the treasure banknotes on the table in front of Xue Xiang and Fang Xiaoru, and said with a smile: "This is yours.

"

After saying that, he stood up and left Shi Shiran.

Xue Xiang and Fang Xiaoru looked at Han Du's leaving figure and did not recover for a long time. When Han Du had already disappeared at the door, Xue Xiang murmured to himself: "How do I feel, I have suffered a loss again this time?"

Fang Xiaoru looked up at Xue Xiang in surprise when he heard this, and met his eyes. After a moment of silence, Fang Xiaoru said in a deep voice: "I feel the same way."

Both of them felt that this feeling was too strange. They spent a hundred thousand yuan just to buy a piece of technology. How could they suffer a loss?

Shaking his head, he shook off the doubts in his heart.

Xue Xiang suddenly became excited. One hundred thousand guan, a full 100,000 guan. If this news gets out, it will definitely cause a sensation in the academy.

Therefore, Xue Xiang planned to create a special reward wall to spread the news about the reward of 100,000 yuan.

In the eyes of all the teachers and students, there was a separate wall downstairs belonging to Mr. and the judge, with a few large characters written on it.

"Reward wall? One hundred thousand gold reward"

The person who saw it suddenly had his eyes bulging, and he could only see the words "One Hundred Thousand Passes", and he could no longer look at the rest.

One hundred thousand dollars!

Sun Xian selling a skill for 5,000 guan is enough to make people jealous, and 100,000 guan is enough to make everyone crazy.

In an instant, explosive news came out.

The academy is shocked!

Han Du's requirements were clearly written on the wall, which was to use the kettle to boil water as a basis to find this greater power and how to use it.

In an instant, a shop selling coal stoves next to the academy was crowded with gentlemen and students from the academy. The inventory that was originally intended to be sold for a month or two was sold out in a short time.

Those who couldn't buy it would go directly to the next shop selling coal stoves.

Looking at the empty shop and the cash box filled with treasures, the boss was still in a state of confusion and muttered to himself: "What, what's going on? Is it true that the gentlemen in the academy are short of stoves?"

The same goes for shops selling copper kettles.

After receiving the coal stove, both the gentlemen and the students from the academy lit the fire immediately, filled the copper kettle with water and put it on the shelf. As the water boiled, they really saw the beating lid.

The moment the lid jumped up, everyone who saw it cheered. They never thought that one day they would lose their temper like this for this common phenomenon.

Some people looked excited and couldn't wait to try again.

Some people seemed to be struck by lightning, frozen in place, muttering to themselves: "Man follows the earth, the earth follows the sky, heaven follows the Tao, Tao follows nature, Tao follows nature!"

Some people saw the jumping pot lid and wanted to see how powerful this force was. However, the people in the academy were all smart people, and they knew that a gentleman should not stand behind a dangerous wall, so they did not use their hands to hold it down, but

Find a heavy object such as a brick to hold the lid down.

A raging copper kettle is burning under the kettle, and a large amount of steam is squeezed into the copper kettle. As the air pressure increases, the boiling water in the copper kettle spurts out along the mouth of the pot.

This sight made people stunned. Some of the teachers and students who saw it couldn't help but think, is this power so small? It can't even lift a brick?

But some people looked at the spout of the copper pot in a daze, and finally chose to seal the spout and boil water again.

This time, they saw results that surprised them.

I saw that the lid of the pot suddenly exploded under the squeeze of the steam inside.

The bricks and stones above flew directly upward, and the pot lid flew high into the air and fell to the ground.

It really works!

So within a few days, Xue Xiang received news from Mr. Academy, saying that they had found a way to increase this power. Xue Xiang didn't know whether this thing met Han Du's requirements, so he had no choice but to give Han Du

Find me.

After Han Du looked around, he smiled and nodded, "Yes, your idea is right, but it is just a copper kettle, and its power is still too small."

"What Mr. Han means is to make this copper pot bigger?" Sun Xian immediately understood and asked.

Sun Xian was already a leader in this field, and since he had just tasted the benefits, it was natural that he would not be uninterested in this. Moreover, although he had just earned a large amount of money, he almost used it to buy a house.

Now that there is an opportunity to make money, he naturally refuses to let it go.

What's more, this is 100,000 yuan!

"Of course, such a small copper kettle does not meet my requirements. The power I want is very large. However, it does not have to be made into a copper kettle. It can also be made into a cylinder, as long as it can be sealed well.

Air leakage is the same."

"And it's no use just letting the lid fly. You have to draw out this power continuously. You see, this is what I brought."

Handu opened a small wooden model, which was a structure about an eccentric wheel and a transmission rod.

As Han Du grabbed the wooden pole and exerted force up and down, the eccentric wheel rotated rapidly, and at the same time it drove the transmission rod, causing another round wooden disk to rotate rapidly.

Everyone was stunned to see how the model in front of them converted the upward and downward force into a steady stream of rotating force.

Every Handu had taught them these things before, but they were still confused at first, but they had never thought about how to combine these things organically and rationally to achieve a certain effect.

Just judging from this wooden model, everyone felt that there was still a huge gap between what they had learned and what Han Du had learned.

"Okay, that's really neat. If we can connect the force that pushes up the lid to this rod, wouldn't it be possible to draw out the force?" Sun Xian was the first to react, clapped his hands and laughed.

Others also suddenly realized it, and their faces showed joy.

But Han Du directly poured cold water on them, "If it was really that simple and I would have done it myself, why would I need to spend these 100,000 yuan?"

Letting go of the wooden pole, Han Du clapped his hands and said.

At this time, everyone knew that the reward of one hundred thousand coins was from the Marquis.

But it doesn't matter, no matter who offers the reward, as long as there is real money.

Han Du pointed at the copper kettle and said: "The problems here are very complicated. How to make this force circulate up and down, how to ensure that there is no air leakage, and how to install the rod on it are all problems that need to be solved by you.

."

He asked several questions in succession, leaving everyone speechless.

Every problem can make them scratch their heads. It is impossible to figure it out in a short while here.

Seeing that everyone was at a loss, Han Du continued to suggest: "In my opinion, it is difficult to make this thing by just one person. Anyway, the reward is one hundred thousand dollars, so I think you can unite, and everyone can add firewood to the flames.

Let’s make plans together. Anyway, the bounty is so large, we’ll just divide it when the time comes.”

"Mr. Han's words make sense~"

After Han Du's words fell, many people immediately echoed.

This is indeed the case. Although one person can get the entire one hundred thousand guan by doing it, it is too difficult as the gentleman said. In terms of speed, it is definitely not as fast as everyone working together. Therefore, instead of doing it alone,

Fighting is a waste of time, so it is better for everyone to unite and find a solution together. After all, even if they all share a hundred thousand guan, each of them can still get a few thousand guan.

They are not greedy either. If they can part with a few thousand yuan and buy a house in the capital, they will be satisfied.

Han Du united everyone to prepare to overcome this problem and stopped interfering with them.

Xue Xiang and Fang Xiaoru stood together, looking at Han Du standing with his teacher and students, and couldn't help but sigh: "Sometimes, I really want to see what kind of exquisite heart he has. I can think of it.

Think what no one has thought of, think what no one has thought of.”

Fang Xiaoru glanced at Xue Xiang and let out a breath. He and Han Du had known each other for so long, and he had the same idea. Han Du always did something unexpected and unconstrained. And in the end, it turned out to be the case.

It can prove that Han Du is right.

The movements in the academy naturally spread throughout the capital very quickly.

After all, it is about a reward of 100,000 yuan. Such a large amount has been unheard of since ancient times. Countless people are curious about what the academy wants to do, and it can actually be like this

This blood.

It's a pity that this reward is only for college teachers and students. No matter how greedy others are, they can only stare.

But even if they could just take a look, countless people refused to take their eyes off this topic. Not only did they want to see the reward of one hundred thousand yuan, but they also wanted to see who the reward was for.

At the same time, the Ministry of Works reported to Lao Zhu that he wanted to send the gantry crane from the academy to the Ministry of Works. The reason was that the Ministry of Works was responsible for the construction of a large number of palaces and cities every year, and the gantry crane could not only be used to lift goods, but also bricks.
