Liu Zhang saw that it was Liu Hong, Huang Chengyan and Pu Fang.

I saw that the three of them were not only out of breath, but also somehow unkempt, unkempt and embarrassed, especially Huang Chengyan, who even seemed to have lost his beard.

Liu Zhang thought something was wrong, so he hurriedly greeted him, and asked in a loud voice: "What's going on, what's going on, what's wrong, why are you so embarrassed?" ”

"It's done, it's done... up..."

"What, what... What became of it? ”

"That's... That... That, fire..."

Huang Chengyan was panting and was about to speak, but Liu Hong hurriedly stopped the conversation and said, "Thor, lord, is the wrath of Thor." ”

Only then did Liu Zhang know that they were talking about gunpowder.

Liu Zhang looked at the appearance of the three people, and it was estimated that the three of them experimented overnight, and it may not even be useful for breakfast.

"A few gentlemen have worked hard, so let's go to the study, eat slowly, and talk slowly." Then, Liu Zhang welcomed the three people into the study and asked someone to bring them breakfast to enjoy. Then he ordered that no one should disturb or come near.

"A few gentlemen are too anxious, there is no need to rush so much, it is easy to get tired."

"Ji Yu, don't talk nonsense, you know people like us, once they know new knowledge, it must be verified immediately." Huang Chengyan muttered back while eating.

"Huang Gong is right, if you don't understand, you won't be able to sleep well when you go back. It just so happens that there is everything in the laboratory, and the three things that the lord said happen to be there, and you can use it after a simple treatment. Moreover, at night, there happened to be no one in the laboratory, so the door was closed. It's also very confidential. Again. The lord said it very clearly. The ratio of one, two, three, and there are only six possibilities, and the results can be tested very quickly. Liu Hong was also very excited.

"The test is the test, why are you so embarrassed, why is Huang Gong's beard burned?"

"It's not that I complain about Lao Pu, I have to say that if I don't say anything, I can't see the effect, I have to get a little more, get a little more. The result is good, boom guy, directly burned my beard, and the two of them are also disgraced. Ha ha. Huang Chengyan talked about the interesting story of the three of them when they were experimenting while eating.

Liu Zhang was terrified when he heard it, these three goods are the fearless of the ignorant, and he said that he should be careful, these three are good, they are completely his mother's second pole, two goods. Fortunately, it was not encapsulated, otherwise it would have been fatal.

"The three of them are still happy. I told you to be careful, and you were so careless. What if something happens? ”

"I really can't see it if it's missing. To see the ashes left after burning, the effect is not obvious without it, and it is not easy to see. Lao Pu muttered in a low voice.

"That's it, Huang Gong, since you have a beard like this, why don't you let me show my skills and help you repair it?"

"Repairs? How to repair it? ”

"Simple." Liu Zhang said, took out a delicate small scimitar with a sheath, and gestured: "Of course, it's all scraped off, like me, how refreshing." ”

"No, well. The body is skinned, and it is received by its parents. Besides, like you, it's immature, with a hairless chin, and can't do things well. Lao Huang was a little reluctant to let him burn his beard.

"Huang Gong, you have to think like this, there is no hair on your chin, so you look young. What's more, if you look like this, my sister-in-law will definitely not follow it, how will you deal with it when the time comes. It is said that you are a dissolute and uninhibited celebrity, how can you be a bit of a celebrity, how can you stick to secular etiquette like ordinary people. ”

"No, you can have the demeanor of a celebrity and a gentleman, the key is Ji Yu'a, I'm not very relieved of you, don't shave off your beard, and then break my appearance when you turn around."

"Don't worry." Liu Zhang's promise.

After waiting for a few people to finish eating, Liu Zhang asked people to bring water, linen and other supplies. Wrapping Huang Chengyan's neck around the bottom of his neck with a linen cloth and cleaning his face with wet wipes, Liu Zhang dipped the scimitar in the water, and then began to repair Lao Huang's beard.

After repairing it, wipe it clean, comb his hair, Liu Zhang took the bronze mirror and let Huang Chengyan see the effect himself.

"Look, yes, don't you feel like you're a teenager younger, and you're back in your twenties."

"It's pretty good. It looks a lot younger. Liu Hong and Pu Fang also chimed in.

"Well, yes, it feels quite refreshing. But it's still a little weird, no beard, it's weird to touch, it's not used to it, how do you feel like a eunuch in the palace. Lao Huang looked at the mirror, Gu Ying felt self-pity and self-pity.

A few people laughed.

"I still blame you Academy of Engineering, the glass has been out for so long, and I haven't even got a mirror. If it is a glass mirror, you will find that after trimming the beard, it will definitely be a big change, and when you go back at night, your sister-in-law will definitely like it, and she will definitely keep it with you a few more times. ”

"Stinky boy, I learned badly when I first got married. The mirror, as you imagined, never came out, and the mercury water was very difficult to attach to the glass. I guess it's up to the Taoists you brought back. ”

Liu Zhang proposed to the Academy of Engineering that by coating one side of the glass with mercury, it can be made into a glass mirror.

The glass mirror is certainly countless times better than the current copper mirror.

Liu Zhang knew that there was a silver mirror reaction, but Liu Zhang couldn't figure out what to do, so he could only vaguely let the Academy of Engineering explore it on its own. So, so far, there hasn't been much progress.

"Lord, can you show that knife just now to your subordinates?"

Pu Fang was born as a blacksmith, and in front of Liu Zhang, he was much more restrained than Huang Chengyan and Liu Hong. Huang Chengyan and Liu Hong are both academic friends with Liu Zhang, and they are not big or small in private, they can be said to be year-old friends, and they often joke casually.

Pu Fang is a craftsman, and the iron striking in the past was handed down from his ancestors, plus Pu Fang's own years of experience. Liu Zhang recruited Pu Fang at the World Heroes Conference, and Pu Fang jumped to become the upper-class figure in Shu now. And Pu Fang also lived up to Liu Zhang's expectations, and the current substantial improvement in the level of steelmaking in Shuzhong is almost entirely due to Pu Fang's strength. However, Pu Blacksmith is still very low-key in his bones.

When an iron striker encounters a good knife, how can he let it go.

"Really, this knife seems to be very sharp."

Several people took the knife that Liu Zhang had just shaved Huang Chengyan with and studied it carefully.

"Yes, I bought it from a stall in Hanzhong. It looks small and useless, but the molten steel is good, and the quality is much better than the dagger you gave to the flying army. This is flowing from the Western Regions, take a closer look. ”

"Really. Ji Yu, can you still buy this thing? Can the seller be found? ”

"Enough. Now there is a famine in Liangzhou, and many people have fled to Hanzhong, so some of the preserved things are taken out and sold. It's such a mess, it's definitely hard to find people, or you write a letter to Guoyuan and ask him to help keep an eye on it. ”

"If we can't find anyone, we'll have to take the knife."

Huang Chengyan said, and he didn't see how he moved, and the knife was gone. Then the three guys got up and walked out.

"You are so disrespectful, you eat and drink and bring it, you are robbers." Liu Zhang drove away and shouted: "That knife is what I used to shave." ”

"You are young, what kind of beard do you shave, there are few hairs, what is there to shave." (To be continued.) )
