After the banquet, Liu Yuanqi, who was drunk, said goodbye and left, walking a little shaky, and finally Liu Bei carried him back. Liu Hong also drank more cups, had a terrible headache, and went to rest early. Deng carefully laid out the futon for Liu Ze, sat on the couch and talked to Liu Ze in a low voice until the second half of the night.

When he woke up the next day, Liu Hong felt that his condition seemed to have worsened, he was groggy, tired, and coughed even more. He didn't take it seriously at first, thinking that he just drank a little more yesterday and still went to work at the county office. But the next day, he had a high fever that did not go away, he could not get up, and he coughed violently, with blood in his sputum. Panicked, Deng hurriedly asked the town's doctor to take a look, and the doctor was probably a barefoot doctor, who looked at it and said that it was okay to prescribe medicine.

But for a few days, Liu Hong's illness became more and more serious, and Deng had to beg Liu Yuan to go to Zhuojun City to invite Dr. Zhang from the Rejuvenation Hall. Liu Yuanqi hurried to the city, originally Dr. Zhang did not go out of the clinic, and he couldn't stand Liu Yuanqi's soft grinding and hard bubbles, so he charged double the outpatient fee before arriving in Lousang Village.

The doctor looked at Liu Hong's complexion, called the pulse, just shook his head and sighed, packed up the medical bag and left, and just said to Liu Yuanqi who asked: "Prepare for the future." And he went out.

Deng couldn't help but cry with grief after hearing this, and Liu Bei also cried endlessly.

Liu Ze knelt down in front of Dr. Zhang and stopped him, pleading, "Please save my father." ”

Doctor Zhang sighed and said, "If you don't do your best, it's really that Ling Zun is already terminally ill and blind, and he can't go back to heaven, and he is really powerless." Unless ......"

Liu Ze was overjoyed and said, "Unless what? Sir, please? ”

"It is rumored that there is a divine doctor Hua Tuo in Qian County, who has the medical skills to bring the dead back to life, if he can be healed, Ling Zun may still be saved?"

Liu Ze said hurriedly: "Then dare to ask sir, where can I find Doctor Huashen?" ”

Dr. Zhang shook his head and said: "Doctor Hua has traveled all over the world, has no fixed place, the dragon is not seen, and the old man has been admired for a long time, and he only hates not to see each other. ”

"Thank you Mr. for your advice, Ze is willing to search all over the world, and I will also invite a Chinese doctor."

Doctor Zhang smiled bitterly: "It's difficult, don't say that the son can't be found, even if he is found, Ling Zun is probably no longer alive." Hey, I'm leaving. ”

Yes, my father is dying, the world is so big, even if Hua Tuo can be found, how can my father's illness wait so long? Liu Ze stood up helplessly, his heart at a loss. I remember that "Romance of the Three Kingdoms: The Biography of the First Lord" said that the first lord Shaogu, that is, his father died when he was a child, but when he died and what disease he died of, Chen Shou did not say, and the people of later generations do not know. Now it seems that Liu Bei is in his teens, and it should be Liu Hong's limit, and even the famous doctors in Zhuojun City have no medicine to treat, I'm afraid Liu Hong really can't survive this hurdle.

Although Liu Ze is not very familiar with medical science, Liu Hong's illness is just a slight cold caused by pneumonia in his opinion, which delays for a while, and is co-infected. But now it's the Han Dynasty, go there to find antibiotics.

But he didn't want to give up, since he was reborn in this family, he couldn't watch his father die, the already impoverished family would be even worse, and Liu Bei would be reduced to a smuggler as in history, struggling at the lowest level of society, he couldn't and wouldn't allow history to repeat itself - Liu Ze roared wordlessly in his heart.

Penicillin! In the later life, penicillin can be bought for only four cents, Liu Ze never thought of its preciousness, but at this moment, Liu Ze silently prayed to God in his heart - God, give me a bottle of penicillin, as long as one bottle is enough!

The sky is silent, and the autumn breeze is blowing.

Liu Ze sat in the courtyard with a frown, and the sun of Hexi was basking on his back, but he didn't feel hot at all, the sadness in his heart filled his body and mind, a person's ability is limited after all, even if he has two thousand years of wisdom, but at this moment, it is useless.

There is a pergola in the courtyard, supported by four wooden pillars, and covered with thatch, so that you can cool off in the courtyard when it is hot. But now it's autumn, the weather is getting cooler, and the pergola has been unvisited for a long time. Next to the pillar lay a few watermelons, one of which was broken and rotten, and the smell of corruption permeated the air. Liu's wife was busy taking care of her sick husband and had no time to clean up, so the day before yesterday she told Liu Bei to throw away the rotten melon, but Liu Bei never cared about it and ignored it at all.

Liu Ze walked over helplessly, picked up the rotten watermelon, and prepared to throw it away.

The watermelon had been rotten for days, completely rotten, juice dripping all over the floor, and a large fluffy pale green mold patch on the festering rind. Liu Ze's heart was shocked, and a flash of inspiration flashed in his mind, although he didn't seek to understand it in his previous life, he still remembered some anecdotes, there was an interesting story about the invention of penicillin, although Fleming discovered penicillin but could not purify it, and later a scientist Flory took over his continued research, and once accidentally bought watermelon in a fruit store and found that there was mold on a rotten watermelon, which was extracted and cultivated into high-purity penicillin.

Liu Ze squatted down, carefully scraped off the mildew on the rotten watermelon, and put it in a crockpot, Flory used a culture liquid made of corn flour, there was no corn in the Han Dynasty, Liu Ze used corn flour to mix the culture liquid instead. Liu Ze has studied biology and chemistry and knows that bacteria can multiply quickly at the right temperature. He put the crockpot into a large pot and poured warm water, although there was no thermometer, Liu Ze could also test the water temperature of about forty degrees with his hand.

But the problem is, there is no microscope in this era, Liu Ze can't know how many units of penicillium he cultivates, if the unit content is low, it will not be sterilized at all, if the unit content is too high, it will become a fatal culprit, and the use of penicillin also has to be skin tested, if Liu Hong is allergic, it is also fatal. But now Liu Ze has no choice, Liu Hong's life is hanging by a thread, he can only be a dead horse and a live horse doctor, he can only pray that this penicillium can have some curative effect and Liu Hong is not allergic to penicillin. Liu Ze was busy all night, constantly changing the pot with warm water, and only poured out the contents of the crockpot at dawn.

Liu Hong knew that his time was short, so he said to his wife who was guarding the couch: "Life and death are fate, wealth is in the sky, today's limit has come, you should respect yourself, don't be sad." ”

Deng Shi cried: "Husband, you can't go, how can we orphans and widows survive?" ”

Liu Hong sighed and said: "The mandate of heaven cannot be violated, after I go, you can remarry, don't be hard, but my two children must not change their surnames to his surname, and this is the root of my Liu family." No matter how difficult it is, let them read, remember. ”

Deng couldn't stop crying.

Liu Hong said to Liu Bei again: "Bei'er, you have to be filial to your mother, diligent in studying, you have a chance to get ahead, you have to treat your brother well, Ze'er Fang has come back, but he has to leave for his father, the eldest brother is like a father, I hope you can treat him well, and in the future, your brothers will work together to resonate with the family." ”

Liu Bei responded and cried incessantly. Liu Hong saw it, but he didn't see Liu Ze's figure, and sighed and said, "Where is Ze'er?" ”

Deng Shi hurriedly wiped away his tears and said, "I'll look for it." ”

Before she could go out, she saw Liu Ze come in with a large coarse porcelain bowl, full of a large bowl of half-yellow, half-green, half-thin and half-thick soup, handed it to the couch, and said, "Father, please drink this bowl of medicine first." ”

Liu Hong shook his head and said with a wry smile: "My illness can't even be cured by Dr. Zhang, let alone ...... Don't drink it. ”

Deng Shi was surprised and said, "Ze'er, where did you get this medicine?" ”

"The child once saw this home remedy in the master's hundred-volume collection, which is dedicated to treating typhoid fever, and the child is eager to save his father, but he doesn't know if this medicine is really effective, but even Dr. Zhang has never been cured, so he is brave enough to take the medicine, and ask his father to try it."

"Ze'er, where did you get the money to buy the medicine?"

"This medicine is not owned by pharmacies, it is all ordinary things, but it has to be carefully blended, and it takes a day and night to complete."

Liu Hong was greatly moved, and said: "Good boy, it is enough for you to have this filial piety, but if my destiny returns, how can one or two medicines be cured?" Now that my father is gone, the two brothers need to help each other, never abandon each other, my family has a future, and I can also look at it under the nine springs. ”

Liu Ze hurriedly said: "Father must not talk about the destiny of heaven, and those who must win the truth of heaven." ”

Deng also persuaded on the side: "Husband, for the sake of the child's filial piety, you have the right to take this bowl of medicine, and now there is only a dead horse as a live horse doctor." ”

Liu Hong nodded silently, struggled to get up halfway, drank the bowl of medicine, and then lay down weakly, unable to speak anymore. Liu's wife folded the quilt and retreated in tears.

The next day, Liu Yuanqi came to visit, originally thought that Liu Hong was terminally ill and blind, and was afraid that he would die soon, but as soon as he entered the door, he saw that Liu Hong's complexion had improved greatly, and he couldn't help but be surprised: "Yesterday, Dr. Zhang said that there was no cure, and today I see that Brother Hong's complexion is so good, it must be ......."

Deng said: "Yesterday, Ze'er didn't know where to find a party, and it took a day and night to make it. ”

Liu Yuanqi was even more surprised, turned back to Liu Ze and said, "Ze'er, where did you get this prescription, which has the effect of bringing the dead back to life?" ”

Liu Ze thought to himself, ancient medicine was so backward, even the most common pneumonia became an incurable disease, no wonder the mortality rate was so high. But he really couldn't explain what bacteria and the like were, so he had to excuse himself and replied: "Back to my uncle, when I was in the mountains, I was rescued by an unknown old man, and he had a hundred books in his cave, and I also accidentally saw it from a book, which specializes in treating typhoid fever, but I don't know whether the medicine and disease are similar, and only because there is no medicine to cure, I dare to take a risk." ”

Liu Yuanqi couldn't help but be overjoyed and asked, "What's the prescription?" ”

Where could Liu Ze get any prescription, so he said: "The little nephew just remembered a few flavors, and he didn't copy the prescription, in fact, these flavors of medicine are also very ordinary, but they have to be carefully blended." ”

Fortunately, Liu Yuanqi didn't understand medical science, so he didn't ask about the prescription anymore, and sighed: "Brother Hong has such a noble son, and he shouldn't die." ”
