However, before inventing the electric light, Zhang Mingwei felt that he had to do some other things, and by the way, he explained the importance of the foundation of the technology tree.

After traveling through time in the 15th year of Chongzhen, the first thing was to save the nation and survive, so in terms of scientific and technological knowledge, I basically focused on everything. Most of the new learning books written by Zhang Mingwei were the contents of later primary school and middle school textbooks.

Even this took him a lot of extra time.

The Ming Dynasty Capital Academy has now been renamed the Ming Dynasty Capital University. Although it has been established for more than a year, Zhang Mingwei's actual teaching time is actually very limited. Either to lead troops to fight, or to plant technology trees, or to participate in the decision-making of national affairs, etc.

Although Xinxue is due to Zhang Mingwei's own power, and at this stage, if you learn Xinxue well, you may be able to become an official. Under such various temptations, many scholars do learn Xinxue.

However, in Zhang Mingwei's view, this is still not enough.

If he suddenly disappears, Xinxue's greatest support will be gone. If one fails, Xinxue is likely to suffer major setbacks.

What Zhang Mingwei wants is to enlighten people of this era. Let them realize the true charm of new learning. Let them realize that there are many unknown things in this world that they can study.

To do this, we need to subvert the perceptions of people in this era. This approach is the most shocking and can attract them to learn new things spontaneously.

The steam train is one, and the previous electromagnetic rod demonstration at Huangji Palace is also one. These are all acceptable. But it's not enough. There are many things that can subvert the cognition of this era in science, such as the invention of the electric light. The prerequisite for this is to conduct experiments that can subvert the cognition of this era.

Therefore, since Zhang Mingwei wants to invent the electric light, he doesn't mind doing a few more shocking experiments.

No, he was giving a lecture in the Ming Dynasty Capital University, just to start experiments.

Emperor Chongzhen knew about it, and naturally he would not miss the opportunity to feast his eyes on it. He decided on the spot that he would visit in person on this day to open his eyes.

When he was like this, all the civil and military officials naturally wanted to follow him.

However, the seats were limited, so Emperor Chongzhen didn’t even need to ask Zhang Mingwei, he just gave them the no. Among the officials of the Ming Dynasty, only the Cabinet and the Supervisor of Ceremonies were allowed to accompany him to observe.

Zhang Mingwei's teaching subjects this time were of course his disciples, including Fang Yizhi, Song Yingxing, Huang Zongxi and others. These people must be present to listen.

In addition, Zhang Mingwei also allowed his disciples to introduce people who they thought were talented in the new learning to attend together.

As soon as the news spread, the capital immediately became a sensation.

Duke Xingguo is going to do some weird experiments again, and the emperor, the cabinet, and the Supervisor of Ceremonies will all be there to listen.

Who wouldn’t want to participate in such an occasion?

So, almost overnight, there were countless new enthusiasts in the capital, and they all thought they were talented.

Since there was no other way, I went to Fang Yizhi and others and asked them to help introduce me, so that I could have the opportunity to participate in this grand event.

Even though it was snowing, it did not stop the enthusiasm of these people. The house of Fang Yizhi and others was really crowded, with all kinds of people coming to visit with all kinds of connections.

However, those who dare to recommend people randomly such as Fang Yizhi and others are of course recommended based on real situations such as true talent and practical knowledge. Otherwise, if you just recommend someone based on who gives you more money, then your future will probably end here!

Moreover, these people are basically academics and technical officers, and they themselves will hate such things. So in the end, the people they introduced followed the rules.

On December 15, the eighteenth year of Chongzhen, heavy snow fell on this day, but it could not stop the curiosity of the people in the capital. They were not qualified to go to the scene, so they were waiting for news in restaurants and teahouses, guessing what shocking move Xing Guogong would do this time?

Of course, they couldn't guess it and could only wait for the news. The topic quickly changed to Duke Xingguo.

"Why do you think Duke Xingguo knows so much? It's like he knows astronomy from above and geography from below, just like the sages!"

"Well, you said that Duke Xingguo knows astronomy and geography. Why do I feel that it is a bit insulting to Duke Xingguo!"

"That's right, Duke Xingguo is not only astronomical and geographical, he is really all-powerful! A sage? Which sage can compare with the Duke?"

"Ah, they are all raised by their mother and father. Why is Duke Xing so smart, but we are not as smart as him?"

"How do you know that the Duke of Guo was raised by his mother's biological father? Do you know the origin of the Duke of Guo?"

"..."

As they talked, these people returned to the old problem. It can be said that the origin of Duke Xingguo is the biggest mystery of this dynasty.

However, the current emperor knows. However, if the emperor doesn’t say anything, who will know?

Some people have speculated that Duke Xingguo may be a god in heaven who came down to earth to revive the Ming Dynasty under the orders of Taizu.

While they were discussing this, outside the teaching building of Ming Dynasty's Capital University, there was a guard in Jinyi standing outside. After checking their attendance certificates, they all pricked their ears and listened to what was going on inside.

Anyone would be curious about Duke Xingguo's experiment, and the imperial guards were no exception.

In the classroom, Zhang Mingwei stood on the podium, looked at the heads below, and said with a smile: "I think everyone already knows that the air that we can't see or touch actually contains something."

This was something he proposed when he was in Chongzhen's fifteenth year. Therefore, over the past few years, this has become common sense. At least these people present knew this.

Seeing that everyone below was nodding, Zhang Mingwei smiled again and asked: "Then I want to ask you, how much do you know about this air? You can raise your hands!"

Fang Yizhi and others are already used to the proper teaching methods for future generations.

After hearing his words, they all raised their hands. There is an emperor watching behind you, so it would be weird not to be more positive!

Their answers did not exceed Zhang Mingwei's expectations, they all said there was oxygen or something.

In fact, regarding this point, Zhang Mingwei proposed the phenomenon of burning candles last year to illustrate this point.

Fang Yizhi and others all have the task of researching and developing technology in their hands, and they have no time to research at all. Therefore, their conclusions are actually what Zhang Mingwei said.

There were no surprises, and Zhang Mingwei didn't take it seriously, so he continued to ask them: "Then let me ask you again, does this air have power, and how powerful is it?"

Upon hearing this, Emperor Chongzhen, including Emperor Chongzhen, was immediately dumbfounded. Subconsciously, some of them used their hands to push and push, but they couldn't feel any strength at all.

"Teacher, I'm afraid the air doesn't have much power, so we can't feel it at all!" Fang Yizhi replied to Zhang Mingwei, "But in the water, we can still feel some of the water's power!"

Zhang Mingwei listened and did not comment, but continued to look at the others.

Seeing him like this, anyone familiar with Zhang Mingwei knew that Fang Yizhi's answer was probably wrong!

Therefore, they all kept their mouths shut and no one spoke to avoid making mistakes!

Emperor Chongzhen didn't have so many worries, but asked doubtfully: "Sir, is this air very powerful?"

Zhang Mingwei laughed after hearing this and said: "How powerful is the air? I won't answer it for now. I will give you an experiment and then it will be clear at a glance!"

Upon hearing this, everyone immediately became curious. They have been waiting for this experiment for a long time.

"Let's go outside!" Zhang Mingwei waved his hand, turned and walked out and said.

Outside this classroom, there is a shed. Snowflakes fell on the roof of the shed, but there was no snow on the ground.

I don’t know when Princess Kunxing was already waiting here. Seeing Zhang Mingwei coming out with his father and others, he greeted them with a smile.

Emperor Chongzhen noticed that beside his daughter, there were already two iron objects, which seemed to be two spheres, half of each, that could be put together.

He immediately knew that his husband's experiment was probably related to this thing.

Zhang Mingwei waited until everyone was in place, and without saying a word, he let people start the operation first.

I saw Liu Jin, his assistant, commanding two Jinyi guards to fill the two hemispheric shells with water and put them together, and trapped them with ropes. Because of the cold weather, the water is hot water, but it does not affect the experiment.

Then, the water was pumped out through the air nozzle installed on the hemisphere. When the water could no longer be pumped out, the faucet on the air nozzle was tightened and closed.

After finishing this, Zhang Mingwei smiled and said to his students: "Now I want to cut this rope, what do you think?"

Perhaps it was because Emperor Chongzhen was present that no one dared to respond to matters that were uncertain.

Emperor Chongzhen felt it himself, and he replied: "Sir, if the fixed rope is cut, of course these two iron knots will..."

When he said this, he regarded his two hands as the two hemispheres, then separated them, and then continued: "Cut it in two and fall to the ground!"

Zhang Mingwei immediately laughed silently after hearing this. Seeing that no one else had an answer, he motioned to Zhu Yuluo to cut the rope.

Everyone present, including the guards in uniforms who were on guard, couldn't help but pay attention to the two hemispheres.

Although cognitively, they thought it would be what the emperor said. However, based on the fact that the Duke wanted to do an experiment, it seems that it would not be what the emperor said.

Thinking this way, they all stared at the results with great curiosity.

Sure enough, after Princess Kunxing cut the rope, the two hemispheres were still together, not divided into two at all.

"Haha!" Emperor Chongzhen laughed when he saw it. Sure enough, this experiment was beyond his expectation, and today was not in vain!

But who knows, something unexpected will happen later!
