Chapter 21 Electrostatic Ball Device

……

"Brother, who is this person? Why haven't I seen him here before?"

Li Shimin asked Li Jiancheng seemingly unintentionally.

"His name is Wu Wen, and he is just an editor I recruited a few days ago." Li Jiancheng replied casually.

"Oh!"

Hearing this, Li Shimin stopped asking questions and turned to talk about the main purpose of his visit to the Eastern Palace today.

"Brother, the emperor wants to kill Dou Jiande. I hope you can join me in persuading the emperor not to kill him. Even if you imprison him or put him in jail, you can't kill him."

Li Jiancheng seemed not to hear what Li Shimin said. He picked up the wine glass and drank it all in one gulp.

After a long while, he said slowly, "Second brother, this is what father wants. As sons, how can we disobey father?"

Li Shimin continued, "Brother, Dou Jiande has done many good deeds in Hebei and is deeply loved by the people of Hebei. If Dou Jiande is killed, it is very likely to cause instability in the hearts of the people of Hebei, which will lead to rebellion!"

Hearing this, Li Jiancheng laughed and said, "Second brother, you are really worrying too much. It's just Dou Jiande. What does it matter whether he lives or dies?

Now it is the world of our Great Tang. Killing him can show the majesty of our Great Tang and deter the local people from rebelling."

"Besides, even if someone dares to rebel, we have you, the General of Heavenly Strategy, in the Tang Dynasty. What enemy can't we pacify?"

Although Li Jiancheng was praising Li Shimin, his tone was full of another meaning.

In response, Li Shimin didn't say anything more. He sighed helplessly and then started drinking alone.

In the corner, Wu Wen listened to the conversation between the two and recalled relevant historical information in his mind.

At the end of the Sui Dynasty, many heroes emerged, among which four forces were the most powerful. For a time, they formed a four-way confrontation and restrained each other.

They are Li Yuan, King of Tang, Li Mi of Wagang, Wang Shichong, King of Henan, and Dou Jiande, King of Hebei.

Li Yuan sent Li Shimin to attack Wang Shichong in Henan first. Dou Jiande sent troops to support Wang Shichong, but he was unexpectedly captured by Li Shimin on the way.

Judging from Dou Jiande's resume, he was actually a very powerful character and a great man, but it was a pity that he met Li Shimin.

After Dou Jiande was beheaded by Li Yuan, a rebellion broke out in the Hebei region where he was located.

What Wu Wen remembers most vividly is that the leader of the rebellion was a man named Liu Heita, who was an extremely powerful and exceptionally powerful man.

He defeated the allied forces of Li Shentong and Luo Yi, drove away Xu Shiji, captured Xue Wanjun and his brothers alive, beheaded Li Daoxuan, captured and beheaded Luo Shixin, and almost killed the General of Tiance and the King of Qin Li Shimin.

These glorious deeds of his even earned him the title of "famous general harvester" by later generations.

Thinking of this, Wu Wen couldn't help but shook his head slightly.

He also felt that Li Shimin was right. Dou Jiande really shouldn't be killed. If he was worried about him, he could just imprison him. Why kill him all? It would only cause so many troubles.

Unfortunately, although Wu Wen knew a lot, he couldn't say much, otherwise he would only get into trouble, so he just stayed there honestly and tasted the food in front of him.

A pot of boiled lamb, two plates of pickles, a plate of boiled vegetables, and a plate of dipping sauce next to it.

Although these are not considered delicacies to Wu Wen, they are already a very sumptuous meal for him now.

The banquet did not last long.

Having failed to achieve his goal, Li Shimin simply said goodbye and left.

"Brother, I'll take my leave now."

After filling his stomach, Wu Wen left the banquet with everyone else.

Leave the palace.

Looking at Wei Zheng in front of him, Wu Wen walked closer quickly.

"Wei Xima, I have a small matter to trouble you with."

"You can talk as you like." Wei Zheng smiled and replied. The two walked and talked.

"That's right. I have a master, a doctor from Zhujia Village named Zhu Jiuye. He was 'invited' to a clinic called Qingyitang in Wannian County. I would like to trouble you to find out for me why the people from Qingyitang asked my master to go there? If he is fine, can you let him go home earlier?"

"It's just a small matter! No problem. I'll send a servant to find out."

"Thank you very much, Wei Xima!"

Just as Wu Wen and Wei Zheng were approaching the palace gate, they happened to run into Qin Prince Li Shimin.

"Wei Zheng!"

When Li Shimin saw Wei Zheng, he walked up to him and greeted him enthusiastically.

"His Royal Highness King Qin."

Wei Zheng responded, but did not give him a good look.

Turning his head to look at the black-robed man standing behind Li Shimin, he said in a light tone:
"I have a piece of good advice for you, Your Highness. It would be best if you stay away from these evil people. If the world knew about this, it would affect the reputation of the royal family."

Hearing this, Li Shimin chuckled: "Although Wu Lian and the others are outsiders, they have also made contributions to the country and have made great contributions to our Tang Dynasty. Why should Lord Wei always be hindered by their identities?"

Wei Zheng didn't want to say anything more. He bowed to Li Shimin as a sign of goodbye, then turned and left.

Wu Wen followed closely behind.

Staring at Wei Zheng's departing back, Li Shimin's eyes revealed admiration.

After walking a distance, Wu Wen whispered to Wei Zheng, "Wei Xima, who is the man behind the King of Qin?"

"It's just a lost dog."

Wei Zheng said contemptuously: "They rely on some foreign sorcery to join the King of Qin and do some shameful things. Wu Wen, remember, stay away from them in the future."

"Yeah!" Wu Wen nodded slightly in response.

Wei Zheng then left the Eastern Palace.

Wu Wenze returned to the library to continue reading.

at dusk.

Wu Wen left the East Palace and returned to his residence.

Night falls.

An oil lamp was lit in the room.

Wu Wen was lying on the table, using a piece of charcoal as a pen, carefully drawing the design of a device on paper.

This device is called an "static ball".

In modern times, this is a very popular gadget and can often be seen in some scientific experiment demonstrations.

Its main part is an iron ball supported by a sturdy pillar from below.

When people put their hands on the iron ball, their hair will float up miraculously due to the effect of static electricity.

Wu Wen planned to make such a device, using its electrostatic induction to assist in his internal energy practice.

"Iron ball... copper wire... copper disk... magnet... pottery shard..."

While designing the drawings, Wu Wen was thinking about the materials needed.

He planned to use copper plates and magnets to make a simple hand-cranked generator, and then use copper wires tightly wound around ceramic sheets to make a transformer to generate and regulate current. At the same time, he used coils to create an electromagnetic field...

After listing all the materials needed to make the electrostatic ball on paper and checking repeatedly to confirm that they were correct, Wu Wen returned to bed to rest.
