After breaking off relations, the prince's family regretted it for the rest of their lives.

Zhu Zigeng was reluctant to refuse Chen Changan, so he took the paper nonchalantly.

There were two pieces of paper. On the first piece of paper it was written:

The composition ratio of Tribulus fireball gunpowder recipe.

1.4 jin of sulfur, 2.5 jin of saltpeter, 5 liang of coarse charcoal powder, 2.5 liang of asphalt, and 2.5 liang of dry lacquer, pound them into powder.

Cut bamboo shavings into pieces of 1.5 liang and 1.5 liang, and hemp shavings into pieces of 1.5 liang.

Use 2.5 liang each of tung oil, small oil, and wax, supplemented with thorns and other substances, put it in a bamboo tube, and reserve a fuse.

Zhu Zigeng frowned and turned over the second piece of paper.

Fire lance.

It is tubular, about the thickness of an adult's thumb, about 1.2 meters long, with gunpowder inside and a bullet nest inside the musket.

Next, is the shape of the nest.

The bullet nest is the modern bullet, but it is slightly longer than the bullet.

……

Zhu Zigeng then looked at Chen Changan strangely.

Only powerful emperors or princes would study gunpowder. How did Chen Changan know it?

At least the ingredients are correct, but the ratio is slightly different from the existing gunpowder!

More importantly, there is no mention of immortality in the entire article!

Zhu Zigeng realized that he had misunderstood Chen Changan: "Sir Chen, how do you know that gunpowder can be used to hurt the enemy?"

Chen Changan was stunned for a moment and shook his head slightly.

This is a lot to say, and we have to thank King Huainan anyway.

In the previous life, just a few days after the imperial examination, the King of Huainan led his entire family to Baidi City, and the Zhennan Army rescued two Westerners in the waters they were in charge of.

With blond hair and blue eyes, he looks scary.

Others said they were monsters and wanted to execute them, but two Westerners took out long objects and beat the officers and soldiers to death with a sound like thunder.

The common people had never seen such a scene and they all fled for their lives.

Out of compassion, Chen Changan risked his life to rescue the Westerner and took him to the mountains for recuperation.

Over time, Chen Changan understood Western languages, and Westerners also understood the language of Da Chu.

Later, the two Westerners told Chen Changan that what they had in their hands was called a musket.

These two gunpowder formulas were also left behind by Westerners.

Seeing that Chen Changan didn't say anything, Zhu Zigeng didn't feel disappointed: "Sir Chen, I thought you were like many officials, developing gunpowder just to please the emperor."

"The two formulas are relatively complex, and the research and development of the musket will take some time."

“If you’re interested, stay at the School of Engineering and we’ll explore it together.”

Chen Changan expressed his gratitude and immediately developed gunpowder at the School of Engineering.

The day passed quickly.

Zhu Zigeng left for something, Chen Changan stretched, and followed Zhou Qiankun out of the Institute of Technology.

It was dinner time and there were quite a few people in the Imperial College.

When Chen Changan appeared, there was an immediate commotion and all the women's eyes were on him.

"Look! It's Chen Changan, Chen the Number One Scholar!"

"I never thought that he would be awarded the dignified fourth rank at such a young age and be in charge of all the post stations!"

"Oh yeah, I heard the buses are selling for a lot of money!"

"Chen Zhuangyuan, are you married?"

"How am I?"

These rich women were all crazy and looked at Chen Changan obsessively.

He is young, talented, and can make money. Isn't he their dream lover?

Zhou Qiankun was envious: "Brother, look, you are really popular! When will you find me a sister-in-law?"

Chen Changan turned a deaf ear to the cheers around him: "Which is more important, life or marriage?"

"Escape from Da Chu, and I will find you ten wives. I will make you so tired every day that you can't even straighten your back. Virtue."

Ten wives?

Zhou Qiankun is also a teenager and is interested in these things.

Isn't that frustrating?

There is a dining hall in the Imperial College, and the food there is excellent.

Chen Changan and Zhou Qiankun got their meal and just as they sat down, they smelled a fragrant breeze.

Two women came over, and one of them sat directly opposite Chen Changan.

Chen Changan looked up and saw a thin pair of lips.

Chen Qingwan.

He frowned slightly, but Chen Qingwan greeted the other woman, "Qing'er, didn't you say you wanted to meet the number one scholar?"

"Come here and sit with me."

Shangguan Qing'er was wearing a light blue dress embroidered with the word "Li".

It means that she is from the Imperial College of Rites. If it sounds good, it means she attends important royal festivals. If it sounds bad, she is no different from a dancer or a singer.

Shangguan Qing'er looks very pure and is a very polite person.

"Master Chen, I am Shangguan Qing'er, nice to meet you."

Shangguan Qing'er sat down opposite Zhou Qiankun in a graceful and elegant manner.

Chen Changan had no grudge against Shangguan Qing'er, so he nodded slightly and took his lunch box to change seats.

Chen Qingwan gritted her teeth and said, "Hanzi, what have you done wrong? Why are you so afraid to be with the lawyer? Are you afraid that I will arrest you?"

Chen Changan sneered: "Why would I be afraid to sit with you? I just don't want to be like you, disgusting."

Snapped!

Chen Qingwan slammed the table and yelled, "How can you talk to your sixth sister? Who is disgusting?"

"Is not it?"

In the past, when Chen Qingwan was angry, Chen Changan was still very afraid.

But now, Chen Changan is afraid of nothing!

"How many concubines have you kept by relying on your status as the Princess of Huainan?"

"She was just a love-brained girl, but how many people took her away from her, and how many good boys did she secretly harm?"

"Even though you came to Imperial College, you are still not honest. Who is next? Li Tiange?"

Chen Qingwan was shocked!

Her face was as red as blood, but how could she admit it?

"Fool! Don't spit bloody words at me!"

"Are you slandering me? Don't you have any idea?" Chen Changan laughed and shook his head.

"Your mother cheated on you, and you kept a lover. You really inherited her good genes!"

"I applaud you, bitch!"

When Chen Qingwan heard Chen Changan talking about Chu Yanran, she became even angrier!

"Foolish boy, I warn you, it doesn't matter if you slander me, but you can't insult your mother!"

"My mother is pure and innocent. If you say anything more, I will fight you to the death!"

Chen Changan was even more disdainful!

"You are so pure and innocent, you are so good at using idioms!"

"She can give birth to Chen Fusheng with someone else, what did I say wrong?"

"Like mother, like daughter. She's lowly, and so are you!"

Chen Qingwan was shaking violently, gritting her teeth and angrily said, "I don't want to argue with you about these things, mother is right!"

"Do you think you can do whatever you want just because you passed the imperial examination? In my eyes, you are still nothing!"

"If my elder sister hadn't asked me to see you, I wouldn't bother with you!"

Chen Changan crossed his arms and said, "Chen Hongluo? Oh, she doesn't even have time to wipe her own ass, and she still has the mind to meddle in my business?"

"It's just right that you're here. Go back and tell Chen Hongluo that she'll be in trouble soon!"

Chen Changan turned around, and Chen Qingwan spoke loudly and anxiously.

"Wait! Fool, you've pissed off your mother and she's sick right here at the Chu Family Manor!"

"She is our mother, father, and the sisters all want you to go and see her, don't refuse her!"

Chen Changan was stunned for a moment, then turned around and smiled.

"Chu Yanran is sick again?"

"Is she dead?"

died?

A son actually asked his sister if his mother was dead?

"You're talking nonsense! How could my mother die?"

"Is this what the Huainan Palace taught you? If you can't even be filial to your parents, how can you be qualified to be the top scholar!"

Chen Changan sneered: "Whether I am qualified to be the top scholar is not up to you, but the emperor!"

"You've had enough of playing with Li Tiange. If you want to hook up with Liu Yanhu, you'd better consider the consequences. Li Tiange is not someone you can mess with!"

Chen Qingwan's scalp cracked!

Catching Chen Changan who was about to leave, Chen Qingwan was terrified: "You, you...how did you know?"

"Follow me?"
