Wu Zheng patted his chest, there were two thousand taels of Jiaozi he had just hidden, and he planned to wait until He Lao Wu came down the mountain to get gunpowder, and let him bring it back, so that he would no longer have to worry about his master who was slamming the door.

These Wu Zheng are still sitting in the infirmary, treating people when they are sick, and when they are not sick, he and Chai Hu mix gunpowder together.

Chai Hu didn't know what the use of this black gunpowder was, he only knew that the medicinal materials used in this medicine were all taken out of the medicine cabinet by him, that is, to save Rao, and in the process, he was surprised that the sulfur and saltpeter could still be purified.

You must know that he had already washed the sulfur and saltpeter that the master bought, but he didn't expect that the things he had worked so hard to purify were still unqualified in the eyes of Senior Brother Wu Zheng, which made him feel frustrated and feel very lucky at the same time, because he was fortunate to learn another skill of purifying medicinal materials from Senior Brother Wu Zheng.

This made him under the pressure of Wu Zhengmei, although he felt that the affairs were heavy, but he was happy to do it.

What Wu Zheng had to do was to mix the purified saltpeter and sulfur of Bupleurum plus the charcoal powder he bought according to the scientific ratio, and then use bamboo tubes to make artillery battles and hand them over to He Laowu, who came every three times, to take them back to open mountains and build roads.

In fact, even so, Wu Zheng still felt very bored, but he didn't want to go back so early, because there was one thing that had not been done for the purpose of going down the mountain this time, that is, he wanted Old Man Xia to take a look at his land deed.

Seeing that the rice seedlings in the field are about to grow taller, now that they know that I am in Shenmu Mountain, almost the entire Yuzhou City knows about it, so Huang Thorn Shi and He County Ling will be unable to help but be curious not to take a look?

If they're curious, let's just do it, what if they're jealous?

But I originally thought that it would be logical for Mrs. Xia to show Xia Lao the title deed by herself, but the old man Xia seemed to have forgotten about it, and he didn't come to the hospital to accompany his wife at home, and asked him what his wife's condition should pay attention to, and what to eat is good for his health!

In that case, he would have the opportunity to show him the title deed, but if the old man didn't come, it would matter, even his own master was busy looking for crystals all over the world as if he had forgotten about it, and he couldn't find the opportunity to take him to Xia Mansion all the time.

Could it be that this is self-inflicted, if I didn't give the master and his old man any microscope at the beginning, I wouldn't have taken myself to the summer mansion for a walk now, and I should go there once in the morning and evening!

Just when Wu Zheng was boredly pulling the pen holder on the table, Huang Lao finally came back, holding a flower cloth burden in his arms, mysteriously walked to Wu Zheng's desk, put the burden on the table, pointed to the burden and said, "Look at whether these are suitable." ”

Wu Zheng was bored and picked up the burden with his hand to take a look, inside were four crystals with very good color, which had been cut into four pieces of moderate thickness by craftsmen, although it still looked a little gray and not transparent at all, but that was because it had not been polished, and it should not be difficult to use such crystal pieces to make a microscope after polishing.

"Master, your old man has been looking for seven outside, but only these are the only ones you found?"

"Why isn't such a crystal suitable?"

"How is it not suitable, these crystals should cost you a lot of money!"

Huang Lao said angrily: "You don't care how much I spend, what should I do next?" ”

Wu Zheng took a pen from the pen stand, and began to draw on the paper on which he wrote the prescription on the table, first drawing three convex lenses of different sizes, and then drawing a microscope on the other pieces of paper The shelf of the eyepiece and the lens barrel of the object environment, marked the size and handed it to his master.

Huang Lao took these papers in his hand and looked at them several times, as if he couldn't see a reason with his old man's wisdom, so he asked, "Just these things can see those insects that your eyes can't see?" ”

Huang Lao's question was a little tongue-twisting, but Wu Zheng still understood and said with a smile: "These are just parts, after these things are done, it should be almost the same when they are assembled." ”

"How much worse?"

"Then it depends on the craftsmanship of grinding the mirror, in short, it is a very troublesome thing. Master, these are all parts drawn by disciples, so when you always look for someone to make it, this size must be carded, otherwise you can't go up to the fashion, don't blame me for not reminding you. ”

"You don't have to worry about this, by the way, do you have any experience in sitting in the hall here? Don't have anything to teach you with? ”

Wu Zheng was stunned for a moment, looked at Huang Lao and muttered in his heart: "Could it be that this old man knows about the two thousand taels of silver?" ”

"Master, your old words are very general! How do you ask your disciples to answer, can you be a little more specific? ”

Huang Lao said with a smile: "That is, have you encountered any tricky things to ask for advice as a teacher, for the sake of your sons who are obedient and sitting in the court, the teacher promises to know everything about your son this time, and he will say everything." ”

"So you're always like this, I thought ......"

Huang Lao stared at Wu Zheng but didn't see Wu Zheng's words, so he said strangely: "Why do you think so?" ”

Wu Zheng's eyes rolled, and he opened his mouth and said, "I thought something happened to Old Madam Xia!" After all, since the last time Lu men operated on her, she didn't care about it, and I didn't know how Old Man Xia's condition was. ”

"You can rest assured about this, although the teachers are busy looking for these water lenses, but every morning they still go to the Xia Mansion for a follow-up visit to Mrs. Xia, and she is now recovering well, so that you can indeed use your son's method to treat this carbuncle in the future."

I have to rely on this alone, and your son is enough to leave a name in history.

But your son's heart, Mu Xiu will be destroyed by Lin Feng, not to mention that he is only in his early twenties, and his life has just begun, and it is not a matter for you to have such a big name all of a sudden. ”

"Senior brother, don't worry, the disciple is not the person who covets fame, and making a fortune in this silence is the disciple's life proposition."

Huang Lao smiled: "It's naturally best if you think like this, so for the sake of teachers and people, your surgery is still defective, and your son shouldn't mind!" ”

"Flawed?"

"That's right, there is a flaw, although this flaw is not worth mentioning compared to human life, but in order not to let your son drift too much now, so as a teacher, everyone who uploads this flaw in the rivers and lakes is known."

"Then I don't know what happened to Master?"

Huang Lao glared at Wu Zheng and said, "Old Mrs. Xia was in a coma that day and didn't know the pain, how could you meet a sober person, and you could bear it with such means?" ”

Wu Zheng sighed and said: "Master's words are true, but who told Hua Tuo to die early, otherwise his old hemp will be solved." ”

"Hemp boiling!" Huang Lao muttered to himself.

"That's right! This is the matter of operating on people, Hua Tuo, his old man is the ancestor, and the disciple is just learning zero fur in his dreams. ”

"Dreams! What dreams? 166 Reading Network
