Da Qin: The First Emperor wanted to train me to be the empress

When talking about the safe output of electric energy, Xu Man thought of the wires and cables of later generations and the materials that conduct electric energy.

Taking a deep breath, Fang said: "It requires a sufficient amount of silver, copper, aluminum and other substances."

"And in order to avoid casualties caused by electrical energy leakage, these materials need to be covered with a layer of insulator."

After a slight pause, she added: "I remember that these contents are all in the basic knowledge of physics. You go down and study them carefully."

"In addition, if we want to control the power manually, we have to install a switch in the right place."

“When the switch is on, the power is available smoothly, and when it is off, it stops functioning.”

Xu Man briefly explained many precautions for the use of electricity in future generations to those present.

Then he said: "As long as you study the basic knowledge of physics carefully, you should be able to solve these problems."

Speaking of this, everyone present lowered their heads in shame: "It's the students' fault. They didn't learn the basic knowledge well, so they came to contact with such advanced knowledge."

"The students have learned their mistake."

Several students lowered their heads in shame, with uneasy expressions on their faces, "I made a big mistake, please punish me by Your Majesty and Your Highness."

Faced with their attitude of admitting their mistake, Xu Man was both pleased and a little scared.

What is gratifying is that they apologized promptly after realizing their recklessness and looked for the reasons within themselves instead of shirk responsibility.

The fear is that they are afraid that they will lose their spirit of exploration from now on, thus slowing down the progress of scientific research.

So she quickly said: "Research is about finding the right direction through constant trial and error."

"Of course, it is necessary to avoid some losses during this process."

"However, we should not stop moving forward just because of danger. Researchers are the leaders who are at the forefront of the times."

“Don’t stop eating because of choking.”

"Your Majesty and Your Majesty, please rest assured that the students will work hard to lay a solid foundation and will never make the mistakes of today again."

Her Highness the Queen's words made several students feel moved and excited. "They will not lose their courage to explore the unknown because of this."

"Very good." Xu Man nodded with satisfaction, "I have taken out the charcoal that generates power here. Your next task is to improve it."

“There’s no need to rush into doing anything else until the improvement is successful.”

"only."

Several students bowed their hands and saluted, "I would like to follow the instructions of Your Highness."

Ying Zheng: "When you complete this thing thoroughly, I will personally knight you."

Seeing that his ninth daughter spoke to these people so carefully and with a little respect, Ying Zheng knew how important the creation of this thing was to Da Qin.

Therefore, the tone is a little softer.

"That's it for today, you go back to study first."

"Farewell to Your Majesty, Farewell to Your Highness the Princess, Farewell to Your Highness Yangzi..."

Amidst the greetings from several people, Xu Man took his little sister's hand and walked out of the laboratory with his father.

At some point, Zhenman had left her original place of contemplation and was writing something quickly in one of the offices.

Xu Man made a silence gesture with his father and younger sister, and cautiously approached the office whose door was not closed.

Zhenman could be seen writing what she had just thought of in deep thought with extremely fast hands.

The rustling sound caused by the friction between the pen tip and the paper made Xu Man worried about sparks.

But Zhenman didn't notice the arrival of her father and two younger sisters at all.

She was only worried that her hand speed could not keep up with her thoughts and she would miss important information.

She saw the formulas completed one by one, and the sheets of paper filled with contents were taken away by her and put aside.

Seeing this, Xu Man made a gesture to his father and younger sister, gently closed the office door for her, and then moved away a little before saying, "It seems that the eighth sister has figured it out."
