Huang Lao only made the separating tube because of the needs of his research progress, and Wu Zheng saw the function of the crystal tube in his hand at a glance and also named it, so didn't this son know from the beginning what the green poison element was extracted?

So Huang Lao shook the separating tube in front of Wu Zheng and asked, "Did you know how to extract this green poison element early in the morning?" ”

"Green poison element? This name is so tongue-twisting, why not just call it penicillin, Master? ”

Huang Laojin was in a very good mood, because Wu Zheng came to see him, as the most proud disciple of his old body, in addition to his medical endowment, he didn't expect to be a person who values love and righteousness, which finally didn't make Huang Lao feel that he was blind.

So for some of the words on Wu Zheng's lips, Huang Lao didn't care at all now, on the contrary, he felt that this was lively on Wu Zheng, and it was much stronger than that Mu Na's chai hu.

"Penicillin, this medicine is called penicillin in your dreams?"

"You can call this whatever you like, anyway, there are no Sakura in this world"

Huang Lao thought for a moment and said, "Forget it, let's call it penicillin!" If you want to choose another name, the old man can't think of it. ”

"Why don't the disciple think of one for you, how about calling him Huang Shisan?"

"This thing is a powder after it is brought up?"

"This seems to be! Where are you now? ”

Huang Lao looked at the separation pipe in his hand: "The teacher found that there are some impurities in this penicillium solution that are not allowed in water but dissolve in oil, so I washed it with oil first, and when the oil floated on the water, then poured out the oil and then used dense silk to sift out the impurities in the water, and the rest should be your penicillin!" But now the problem is that the sieve is always not dry, and the penicillin obtained is always impure. ”

"I see, so why don't you use charcoal powder as a sieve?"

"Charcoal?"

"That's right! The refined salt of the disciples is sifted out of the brine salt with charcoal powder as a sieve. ”

After Wu Zheng finished, Huang Lao stood up: "As a teacher, I'll go find charcoal powder to give it a try." ”

"Master, this is not in a hurry, this charcoal has to be ground into powder to be sifted, and it also needs to use a very pure water to shape, these are naturally hard for you to do as an old man, you see if you go to Xia Lao to help, anyway, there are many servants in his family, borrow two or three people to come over and believe that he will not have any opinions."

"It seems that your son really knows the method, so why don't you write it down quickly, so that the teacher can try it."

"The disciple only knows what it is, but he doesn't know why, the reason why he didn't tell the master before, isn't it just that he wants the master to tell the disciple why it is? But now it seems that the master already knows, so there is nothing wrong with telling the master about the later processes, but as for whether it will work in the end, it will have to be checked by the master. ”

After finishing, Wu Zheng picked up the paper and pen that the master used to make records, wrote a simple penicillin preparation method on the table, and then drew a syringe in the back, which was used to make skin trials.

This thing seems simple, but it can't be made with the craftsmanship of Shenmu Village, because the syringe made directly from crystal, the plug in the middle and the syringe cylinder are tightly fitted, and the craftsmen of Shenmu Village do not have this craftsmanship.

But Wu Zheng knew that his master had a magic craftsman in his hands, so why not come to the master today to try it, you must know that the effect of this intravenous injection is far more effective than oral injection.

Of course, as soon as this syringe was drawn, it was inevitable that it would be tortured by the master, and it was only until Wu Zheng knew everything he knew that Huang Lao reluctantly let Wu Zheng go.

It was late at night talking to the master, and the sound of refining soldiers suddenly sounded outside, followed by a violent explosion.

Wu Zheng was shocked, could it be that this authentic thing was not done by Meng Da or let Tuyuhun's people enter the city?

Wu Zheng hurriedly rushed out of the house, and happened to be in the courtyard when he bumped into Seinfeld who came to look for him.

"What's going on with Fei'er? The Tuyuhun people have entered the city? ”

Seinfeld shook her head: "No, I heard that General Meng gave the Tuyuhun people a plan, and I don't know how many Tuyuhun people will be buried in the tunnel." ”

"That explosion just now?"

"Not ours."

"That's good, this hand-to-hand fight with people, we can try not to mix it if we can. Alas...... That's not right! This Yin girl's gunpowder was made? ”

Seinfeld said: "There are those things in the city, and Miss Yin just packs the gunpowder she collects, and it is the kind that is lit with a fire fold." ”

"I see, I thought it was ......"

"Why? Think Miss Yin was tortured at the hands of Old Man Xia? ”

Wu Zheng smiled: "How can it! Xia Lao is a highly respected generation of emperors, how could he do those pickled things. But now it's a great achievement for Miss Yin! ”

"No, people are busy making gunpowder for Old Man Xia right now! How can I have time to ignore you. ”

At this time, Huang Lao also walked out of the wooden house, and when Song Fei'er saw it, he hurriedly stepped forward and saluted: "Fei'er has seen Master!" ”

Huang Lao nodded and said that he had seen it, so he looked at Wu Zheng and said, "If that girl really likes you, you don't let her down." ”

"Who? Fei'er? She is my wife, and I will naturally not fail her in my life......"

"Alright, get out of here!"

Wu Zheng had no choice but to take Seinfeld away, but his own master was too unreal, and he persuaded his son not to live up to the three in front of his wife, is this master so deserving? Isn't that calling your family discordant? But then again, that woman's relationship with the master seems to be quite deep, otherwise how could his old man say such things to himself?

If you have a chance, you must ask him what the hell is going on with the old man, but now! Forget it.

After Wu Zheng left the medical hall, Huang Lao did not stay in the medical hall but went to Xia Mansion, whether he went to ask for someone or not to take refuge, it was better than him staying alone in this medical hall, which also made Wu Zheng feel at ease and returned to the house where his brothers lived with Seinfeld.

This time he attacked Yuzhou City, and the left did not send out the whole army, although he thought so before, but who told Wu Zheng to kill his younger brother's 1,000 men and horses in Qingtang Mountain! Moreover, the national teacher was also missing, and when the news reached his ears, the battle-hardened left immediately sensed that something was wrong.

Therefore, for the sake of safety, he only sent 1,000 people to steal the city through the tunnels this time, while he himself took the rest of the people to attack under the city of Chongqing, and to cooperate with the riots created inside.

It's a pity that at least half of his 1,000 people have now been buried alive by Meng Da, but even so, this left-hander actually climbed to the top of the city, and the combat power of the Great Zhou army once again brushed Wu Zheng's perception of them.

"Why did the Tuyuhun people hit the city wall so quickly? Isn't there 20,000 defenders in this Yuzhou? So easy to get people on the wall? ”

In the face of Wu Zheng's questioning, Chen Sandao didn't know what to do, he used to think that the army of this court was quite capable in front of him! Why did they become weak chickens one by one in front of Tugu Hun Rao? What's more, the people who guard the northern city are still the elite of the imperial court, my elite Yulin Guard and the forbidden army.

He Lao Wu said: "It's not surprising that the soldiers of my uncle's court seem to be like this, what should we do now?" 166 Reading Network
