But Chongzhen still had a doubt that he would not speak up.

"Youming, if you want to increase the electricity by a hundred times, how many potatoes will you have to use?" Chongzhen asked seriously.

Potatoes are life-saving food for the Ming Dynasty, and are strategic resources for the safety of the people of the Ming Dynasty. If potatoes are used to generate electricity, more people will have no food to eat.

But if this electricity is used for war, it is really a magical artifact given by God, but it cannot have both fish and bear's paws, which makes Uncle Chongzhen feel very uncomfortable.

"Hahaha! The Supreme Emperor always cared about the sufferings of all people, and it was really the blessing of my Ming Dynasty." Liu Hongjian was amused by serious uncle Chongzhen.

Chongzhen actually wanted to use countless potatoes to increase the amplitude. No wonder electricity was unheard of for these ancient people. They just thought that this electricity could only be produced from potatoes.

"Everything has its own reason. The chemical substances in potatoes can be converted into electricity, the wind in the mountains and the water in the river can be converted into electricity. As long as all the disciples are united and strive to overcome difficulties, the sun above our heads can also be converted into electricity!"

Liu Hongjian was chatting and laughing, with surprisingly confident face.

"When will it be developed?" Chongzhen asked another question that he was very concerned about.

Yes, when will that situation be realized?

It’s not just a matter of saying that it’s all about increasing the power. This involves too many technical and safety issues. There is no generator or even rubber at this time, so it’s hard to do it!

"It won't take long. As long as the imperial court is willing to strongly support engineering, electricity will definitely be used by the Ming Dynasty within a few years." Liu Hongjian took a deep breath and said in a deep voice.

Among the various power generation methods such as wind power generation, thermal power generation, solar power generation and hydropower generation, hydropower generation is the easiest to achieve and the lowest cost.

But that was in later generations, and the site selection requirements for hydropower generation are high. Without machinery, building super dams requires more manpower, material resources and risks.

But it doesn't matter. He believes in the wisdom of the Chinese. As long as he points out this path, thousands of descendants of the craftsmanship can always do everything.

Besides, he has the instruction manual in his hand.

"Oh, it seems that I will never see you in this life, it's a pity!" Chongzhen sighed.

"A person's death is higher than Mount Tai or lighter than a feather. The Supreme Emperor, your kindness and diligence will be praised by later generations, and now you should live more easily. No one knows what will happen tomorrow, right?"

Liu Hongjian did not immediately say nonsense like other court officials that the emperor would be favored by heaven, live a hundred years, live a long life and a lifetime and a heavenly equilibrium, but instead expressed his views on his simple understanding of life and death.

Sometimes he once thought about what to do if his life was only one day left?

Go find a place to sigh at the unfair fate? Go cry so hard that you beg for the heavens to mercy?

No, no, he wants to hold the three little cuties in his home, eat the last meal, enjoy the last new moon, do things he wanted to do but had no chance and had no courage to do, go...

In short, I will not be self-admiring and will be sympathetic.

"Haha, you will comfort people, but I am not as cowardly as you think. I have already taken life and death lightly now. Now I am happy. If I say there are regrets, I only sigh why my ancestors did not bring you down earlier." Chongzhen said with a smile.

If it were earlier, perhaps the people in the north would not have to suffer so many slaughter!

The potato power generation experiment left hundreds of people, including the teaching master, dumbfounded. Most of the teaching masters stared at the potatoes that Liu Hongjian had eaten half-pulled, two ordinary metal wires, and dead ants in the tray.

For those of them who have been immersed in Confucianism for most of their lives, perhaps new things are even more difficult for them to accept.

But the young disciples are different. They have only a little understanding of Confucianism, and many people even ignorant of literacy when they come to the engineering college.

They are all blank paper for natural science, physics, biology, chemistry, etc., and it depends on what the engineering school can teach them.

The reason why Liu Hongjian came to teach this class to his disciples in the School of Engineering to break their blind admiration for Cheng-Zhu Neo-Confucianism was one of the first reasons, and to broaden their horizons for these young disciples and let them know that science is the only one that can explain everything in the world.

"There are two iron balls in this other tray, but I am no longer interested in demonstrating the experiment for you." Liu Hongjian lifted the red sermon on another tray on the table.

"Interested students can take these two large and small iron balls, climb to the highest floor of this building, and throw the two iron balls down at the same time. You will find that two iron balls of different weights will land at the same time.

As for why, I won’t give you all, it depends on your own thinking.

If someone can understand it with physics, I guarantee that you can be remembered in history." Liu Hongjian picked up two iron balls and let the disciples behind him look at it, and said provocatively.

After Liu Hong said a few of the teachers in the front row could not sit still. Isn’t this a misleading child?

Two objects, one light and one heavy, fall at the same time, so naturally the heavy ones fall first. If you go to the street, you can tell you the answer.

A teacher next to him wanted to stand up and refute, but was held down by his colleagues beside him.

Everyone saw Li Cunhou’s fault. And now the Supreme Emperor is here, refuting in public that the mountain chief was not doing what his subordinates did. If the Supreme Emperor is displeased, wouldn’t he be unable to get along with him?

I had no limits on my words, so I would wait for the class to find a few colleagues to experiment so that the leader of the mountain could restrain his behavior that misleads his children.

But the young disciples later didn't think so. Now they are almost admiring Liu Hongjian, giving them food, clothing and supplies, reading and literacy, and allowing them to appreciate the mystery of all things.

Leave a name in history!

If you can still be famous in history without relying on the imperial examination in this life, what regrets will you be in this life?

"Now, I will announce that from today on the 15th and the end of the month, the teachers of various subjects will take undergraduate disciples out to teach!

The Civil Engineering Department went to study pavilions and towers, the Water Conservancy Department went to field inspections of rivers, bridges and dams, the mining department went to explore minerals in the mountains, and the smelting department went to the workshop to observe on the spot..."

Liu Hongjian calmly and unquestionably announced the new regulations of the School of Engineering to the teachers present. Science and Technology cannot only stay in the textbooks, nor can he obey the teachings' words.

In the face of science, we must dare to question the so-called authority.

The School of Engineering should not be an ivory tower. On it, Wang Shouren studied things and learned knowledge. Now, there are disciples of the School of Engineering who studied things and realized the principles of physics, and the principles of all things.

Go out!

Observe this world, appreciate the steepness of mountains and the dangers of rivers!

Study the wonders of all things, the tiny little bit!
