Just when the army was about to set off.A person arrives very unexpectedly.Zhang Liang actually came to find Shang Wen in person.This surprised Shangwen a little.

"I don't know what's the matter with Mr. Zhang?" Shang Wen asked.

"Oh. Dare to ask Mr. Qin. Is this army going to be deployed?" Zhang Liang asked.

"Yes." Shangwen replied simply.

"Oh. Then Liang will speak directly." Zhang Liang said.

"Say it straight, it's okay." Shangwen still said in the same words.

"Liang is here this time. It is to submit diplomatic documents. Please also pass it on to the King of Qin, Mr. Qin." Zhang Liang said and took out a bundle of bamboo slips.

"En. Alright. I'll leave it to the King of Qin." Shang Wen said while holding the bamboo slips.

"Na Liang is leaving." Zhang Liang said and was about to turn around and leave.

"Wait." Shangwen called.Shang Wen felt that it was too inconvenient to see such a bulky bamboo slip.No wonder the ancients could describe a thing by writing a few words.All because of the writing tool.

"Mr. Zhang, wait a moment." Shangwen said as he ran into his camp.Take out two notebooks and pencils.

"I think Mr. Zhang's writing tools are so inconvenient. This is a little thought." Shang Wen said.

Speaking of Shangwen, he handed it to Zhang Liang himself.

"This." Zhang Liang hesitated.

"It doesn't matter. Mr. Zhang is a literati. It is inevitable for literati to write and draw. These things can just make up for the inconvenience of writing." Shang Wen said.

"What is this?" Zhang Liang asked again.

"Notebooks and pencils. These are made of paper. Pencils use graphite to write easily," Shangwen said.

"That. Liang wrote Mr. Qin here." Zhang Liang was not polite.

"Liang will leave now. Farewell." Zhang Liang cupped his hands and said.

Shang Wen sent Zhang Liang away.Just getting ready to pack up.Ying Yu snatched the bamboo slip from his hand.

"Oh, the letter is flying so fast. Does that guy named Zhang Liang deliver the letter?" Ying Yu opened the document dissatisfied and saw.

"That's not the case." Shang Wen rejected it without hesitation.

"What? South Korea is going to set up an embassy in Daqin. This vixen is also coming." Ying Yu shouted dissatisfied.

"This is diplomacy. Is it a big deal?" Shang Wen asked.

"What kind of diplomacy. I think, I think this Korean princess has bad intentions. Seeing that our Great Qin State is strong and their South Korea is weak, they want to make trouble. Shameless. Too shameless. This matter is not allowed. Absolutely not allowed." Ying Yu shouted loudly.As he spoke, Ying Yu drew his sword casually.Hack and scatter that document on the ground.

"Hey, stop. This is a diplomatic document." Shangwen stopped loudly.

"I don't care if he has documents or not. Anyway, there is nothing good in South Korea. His mind is full of conspiracy and conspiracy. I am doing it for your own good." Ying Yu said indignantly.

"Alas. Shangwen looked at the papers that had been cut into pieces on the ground. It's too late to remedy it now." Ying Yu withdrew her sword in arrogance.

"Let's go. I've packed everything. This place. I don't want to stay for a moment." Ying Yu said, pulling Shang Wen's hand into the carriage.Shangwen didn't want to leave.But he was dragged into the car by Ying Yu.

The carriage soon joined the team and was developed towards Xianyang.

The two people in the car said nothing.Ying Yu was the first to ask.After all, she felt that the atmosphere was a bit dull. "Why don't you talk?" Ying Yu asked.

"What?" Shang Wen replied.

"Say anything casually?" Ying Yu said.

"I don't know what to say and write casually?" Shang Wen said.

"Idiots, idiots, deaf idiots. Dumb idiots." Ying Yu cursed a series of idiots.

Ignoring Ying Yu, Shang Wen took out her notebook and took out a pencil and began to sketch something.Shangwen thought of exonerating Yingyu.If the king of Qin can't see the real thing, he will probably be unhappy.Think here.Shang Wen felt that it was necessary to design a musket.

Thanks to ray mercury.To passivate it, use grease or paraffin.Passivation treatment is to deal with it to improve its sensitivity.It also improves safety.But if it is completely passivated, it is meaningless to change the flint into a percussion gun.Therefore, there are still standards for passivation treatment.This standard is the effect of firing it with a certain amount of heavy objects in free fall at a distance of five inches or a little higher.This standard force is the force generated by the firing device to fire the cap, and then ignite the firing powder.Push the bullet.This strength is tested through such experiments.That's it.Then unified production.The production formula of thunderbolt and the production method of sulfuric acid and nitric acid will directly block the spread of this technology.

Now that Qin State is able to produce flintlock guns on a large scale, these muskets must be put to good use.For example, remove the flint and other objects and change it to a percussion hammer.Improve the ignition method, etc.Thus.The reliability of muskets will be greatly improved.

Shangwen began to draw some sketch improvement plans.After all this is over.Shangwen believes that for some weapons such as grenades and mines, it can also be shot through the appearance of thunder mercury.

But this way.The demand for mercury is very large.Thus, the production of sulfuric acid and nitric acid must be increased.

"Hey. Hey." Ying Yu didn't care about anything after seeing Shang Wen take out his notebook.feel bored.

"I call you that, idiot." Shang Wen had heard it long ago.Deliberately not agreeing.

"I told you to ignore me." Ying Yu kicked her as she said that.

"Hey, you're too harsh." Shangwen shouted loudly.

"Who told you to ignore me." Ying Yu said.

"Didn't I design a musket for you?" Shang Wen said and threw the notebook to Ying Yu.

"What is this? I can't understand it. The painting is messy."Ying Yu said.

"Hey, it's okay if you don't understand it. This is a percussion gun. With this, future guns will be called firearms." Shang Wen said.

"Use a cap, or make it into a primer, and then make it into a bullet. As long as the firing pin is fired, it can be fired." Shang Wen said.

"Really?" Ying Yu asked.

"I'm fine, what are you doing lying to you? But you have to build a chemical plant first, and mass-produce these things before they can be used." Shang Wen said.

"Chemical plant. This is on me." Ying Yu didn't ask the reason of the matter, and directly recruited the chemical plant to her head.

"Forget it. You are the only one with spare money." Shang Wen said.

"That is, I made a lot of money from my father's harem. That's right. Do you have any small inventions? I want to build a chemical plant, so I have to raise part of the money." Ying Yu said as a matter of course.

"This, let me think about it." Shangwen made a thought.

"What do you girls lack?" Shang Wen looked at Ying Yu and asked.

"How do I know? I'm a martial arts girl." Ying Yu said.

"Oh." Shang Wen continued to look at Ying Yu and nodded.

"Why are you looking at me?" Ying Yu asked.
