It was already afternoon when Li Yuanjing received the news, and when he asked the reason for the matter, he smiled, asked people to take out two sticks of penicillin, and walked towards Chang'an without hurrying.

The result was a little unexpected, Ma Zhou hadn't come back yet, and Li Shimin knew the result over there.

But it's not surprising to think about it, isn't everything in your own expectations?

There is nothing to be profiteering, only medicines, and the profits of the weaving workshop are still there, but they have dropped to less than 20,000 per month, and although the shipments are increasing, the price has been falling all the way.

Penicillin is Li Yuanjing's search for a new flashpoint, and after this gang is done, the remaining money in his hand will almost be able to have some room for resistance when facing the family.

The familiar palace, the familiar imperial study, the familiar people, the difference is that the faces of those people are a little anxious.

"Is this real?" Seeing Li Yuanjing appear, Li Shimin couldn't wait to throw Li Jing's letter to him and hurriedly asked.

Li Yuanjing looked down at the contents of the letter and had a rough idea in his heart.

Some are lower than expected, some are higher than expected, how to say, there is penicillin, a miracle drug, and more than 20 people died after surgery, indicating that the quality of the drug needs to be improved.

But because of this, it was also higher than Li Yuanjing's expectations, and he actually lived more than eighty, which he really didn't expect, according to the original idea, it would be good if half of the number of people treated could live.

After all, it's only the second trial, who can have this success rate in the second trial of a new drug?

"Well, if the injury is treated immediately, as long as there are no allergies, the estimated survival rate will be higher!" Li Yuanjing took the game directly without being polite.

"How difficult is this drug to make? And what about the price? Li Shimin didn't have so much heart to talk to Li Yuanjing, he was too tired.

My own brother, of course, if you have anything to say, you can say it directly, and now Li Shimin is still somewhat relieved about Li Yuanjing, after all, he knows himself and his opponent......

"From this letter, we can see that the medicine with low manufacturing difficulty has basically been eliminated, the ten death row prisoners in Chang'an, the six who died have eliminated six production methods, and this time the new method brought to Dingxiang is the new method after the improvement of the remaining four methods, at present, two have been eliminated directly, and among the remaining two, there is a high probability that it will also be eliminated." Li Yuanjing began to talk at length.

"How difficult is it? How much does it cost? Li Shimin glared at Li Yuanjing, could he guess the little idea in the little brother's heart?

If you can't guess this emperor, it's in vain, you don't go to so many places, so many people can test you don't go, you have to go to the front line to test in the army, what do you want to do?

Li Shimin knows Li Yuanjing's thoughts very well, so he doesn't want to talk nonsense with him, everyone goes straight to the point, you offer me to bargain, and in the end, I will finish the matter directly, and I will not be able to fool you if you lie to me.

"It's very difficult, it's not ordinary, I'll understand it by simply talking about the royal brother!" Li Yuanjing paused with a heavy face and continued:

"First of all, there are three things that need to be used in large quantities, the first is noodles, the second is rice, and the third is taro from the south, which must go through more than ten processes for preliminary processing, and then select the ones that meet the requirements to enter the next step!" Li Yuanjing said a lot.

In fact, the most suitable should be yams, but at this time there is no such thing in China, and finally taro is used instead, and the effect feels worse, but ......

Li Yuanjing forgot that the body of the ancients was not forcibly pulled out by various antibiotics, so it was also more sensitive to penicillin that was not very effective in theory.

Because once you take good medicine at the beginning, when this medicine cannot be controlled, there is basically no rescue measure, and the reason is the same.

Now the immunity of the ancient people's bodies to antibiotics is almost zero, so the effect is so good, if you wait for a few decades, penicillin may not be so magical.

However, the boast should still be blown up, as a qualified salesperson, it is not good to brag about it.

"Next, we need to enter the more critical second step, in the second half of the first step of the process, we need to start to change the environment, that is, to keep the temperature in the house consistent, the temperature is too high or too low, the whole batch will be directly wasted, and the second step of processing is more troublesome, I personally went to check, a total of fifty-five processes, the order of each process, and the time of the process have strict requirements, the wrong effect will be wrong, wrong three or four points, this batch will be scrapped."

"The most critical thing is the third step, the medicine at this time is not the current color, but turbid, to find a way to take out the turbidity, one of the six people who died at the beginning did not go through this step, this is not to find a cloth to filter it, up and down, to go through sixteen processes to filter, one of the six people is through ten filtration procedures."

"After doing the first three steps, it is actually considered a success, but the efficacy at this time is very poor, and it is one thing to use it or not, so it is the last step, purification, forcibly improve the purity of the drug, and this step is also the most difficult, I tried to purify it with extracted alcohol, but the result failed, and the efficacy disappeared, and finally I thought of a complex method, and after 30 processes of strict treatment and purification, it was successful."

"But at this time, there is still the last step away from real success, and it is this, the glass bottle, this medicine must be placed in the glass bottle to maintain its effect, and the other containers will probably be invalid in less than a day, and if it is summer, it may be useless in two hours."

"Then I also found that as long as there is no ice outside, this medicine must always be placed next to the ice, if you take it away, it will be better in winter, it can last for a day or two, and in summer, it will be useless for half a day at most."

A penicillin with only more than 30 processes was blown into 100 processes by Li Yuanjing's mouth, and each process was so complicated, as for refrigerated transportation, refrigerated ghosts, anyway, they don't understand, the more difficult things can bluff people, and most importantly, they can sell at a high price!

"Price!" Li Shimin was a little angry, after talking for a long time, he still didn't get to the point, and he was dizzy after saying so much.

Li Yuanjing was happy in his heart, but he still maintained a solemn expression on his face.

"So far, I've invested nearly 300,000 yuan in research alone."

"Where did you get all that money?" Li Shimin was stunned, this seemed to be wrong with the situation he had mastered.

"Your Majesty, Cheng Zhijie privately voted 100,000 yuan!" Fang Xuanling's face flushed, and then he said: "The minister, the auxiliary machine and Ruhui also invested 50,000 yuan each, but they didn't know that they were doing this before. ”

Li Shimin was slightly stunned in his heart, and he pulled the people around me again?

The investment of 300,000 guan is only to study a formula, even if one is sold consistently, it will take 300,000 to recover the research cost.

Li Shimin looked at Li Yuanjing with some dissatisfaction.

"Why don't you come to me if you don't have money? If this matter spreads, how will you let the world think of me? ”
