Another day at dawn, Guan Yu was concerned about Li Mengxi's condition and went to see him early in the morning. As soon as he walked to the side courtyard, Guan Yu saw Li Mengxi squatting there again and vomiting all over the lake.

Walking over, Guan Yu asked with concern, "Xi'er, are you feeling better?"

Li Mengxi spit out the sour water in his mouth, raised his head and forced a smile, "It's okay."

Looking at Li Mengxi's pale face, Guan Yu was extremely worried.

——

Li Mengxi was suffering from a simple cold. He also drank countless bowls of medicine and a lot of hot water. After two or three days, his body not only did not improve at all, but also became weaker.

Liu Bei was worried about Li Mengxi's condition, so he ignored the farming and hurried back to guard it.

Li Mengxi was ill alone, which made a large group of people anxious.

Military doctor Tian Bu came again. This time Tian Bu performed acupuncture, hoping that Li Mengxi would get better.

Not only that, Tian Bu also brought several colleagues with superb medical skills to pool their wisdom and quickly find a way to cure the disease.

Although Li Mengxi had an optimistic attitude and kept comforting everyone, saying that a small cold was nothing to worry about, the military doctor and others were extremely serious.

There were a bunch of people gathered in the room, but no one noticed. Zhang Ning came, holding a bowl of water carefully in her hand. When she saw the crowd of people in the room, Li Mengxi was surrounded by water. Zhang Ning wanted to go over,

He was a little afraid of people, so he mustered up his courage, lowered his head, walked through the crowd, walked inside, walked up to Li Mengxi, and handed the water to Li Mengxi.

"Here." Zhang Ning put the water in front of Li Mengxi.

As a bunch of people watched, Zhang Ning blushed terribly.

Li Mengxi, who was listless and sick, looked up and saw that Zhang Ning was here. He smiled brightly and said, "Sister Ning? You are here."

Zhang Ning lowered his head and timidly pointed to the water in the bowl, "I heard that you are sick. Try drinking some of this water. My father uses this to treat illnesses."

Li Mengxi looked down. When he looked into the bowl, he was stunned.

In the bowl, there is a bowl of water, a handful of branches placed in the water, and a piece of talisman paper.

this……

Li Mengxi's eyes became strange, and he looked at Zhang Ning strangely.

Zhang Ning's father is Zhang Jiao. Zhang Jiao has the ability to draw talismans and apply water. This is both a branch and a talisman. Is it really useful? Will anything happen if he drinks it?

Li Mengxi wanted to refuse, but looking at the worried girl in front of him, he couldn't bear to refuse.

If you eat the talisman paper, you will get upset at most, so just drink it.

Thinking of this, Li Mengxi picked up the talisman water, raised his head and drank it in one gulp. The one was refreshing and the other was bold.

After drinking and coughing twice, Li Mengxi picked up the branch in the bowl, looked at it, and asked curiously, "Sister Ning, what kind of branch is this?"

"It's a willow branch." Zhang Ning answered in a low voice. She hesitated, "My father said that the willow branch must also be eaten..."

When Li Mengxi heard that he still wanted to eat the branches, he hesitated for a moment, smiled, and simply put the branches into his mouth and started chewing them.

I have never eaten willow branches before, but when I was a kid, I made flutes and smoked willow branches. I had the impression that willow branches are bitter. Now when I eat them, they are indeed bitter, bitter and astringent, and it is extremely unpalatable.

Although it was very unpalatable, this was the good intention of others. Li Mengxi's expression remained as usual. He chewed all the willow sticks one after another like chewing spicy sticks and ate them all in his stomach.

When I finally finished eating, my mouth was full of bitterness.

Li Mengxi raised his head and smiled at Zhang Ning nonchalantly. He pretended to be bold and said, "It's not bitter at all, Sister Ning, is there anything else?"

Zhang Ning nodded vigorously and ran out.

Li Mengxi thought that Zhang Ning had gone back and would not come back again.

Anyone can tell that they are polite words. Who wants to eat branches?

After a while, Zhang Ning came back with a pile of willow branches.

Li Mengxi's expression froze.

A pile of willow branches was placed in front of him, and Zhang Ning said happily, "There are still some on the tree."

Li Mengxi's face twitched.

It’s your own fault, so you have to show off.

Eat as much as you want, and stop eating when you are half full.

Li Mengxi had no choice but to pick up the tender willow branches, tear off the willow bark and eat them one by one.

Zhang Ning saw that Li Mengxi was having a lot of trouble pulling out the willow sticks, so he naturally came over, knelt down and helped Li Mengxi pull out the willow sticks one by one.

Everyone in the room, including Liu Bei, Guan Yu, Jian Yong, and a group of military doctors, were watching Li Mengxi and Zhang Ning, one of whom was eating tree bark, while the other with a low eyebrow was quietly helping to hand it over. It was such a childish and interesting scene.

.

Liu Bei smiled. He quietly waved to everyone and motioned for everyone to leave.

After leaving the door, Jian Yong looked back curiously, "Whose family does that girl belong to?"

Jian Yong asked curiously.

"She is the daughter of Zhang Jiao." Liu Bei replied casually.

Jian Yong looked surprised, and then found it extremely interesting.

Zhang Jiao's daughter is actually still alive and has not been executed. Moreover, it seems that the relationship between the young military advisor and that beautiful girl is not ordinary.

Jian Yong smiled, very happily. Everyone has the heart to gossip.

Liu Bei dispersed the crowd because Liu Bei himself believed in the theory of magic. Liu Bei really believed that Zhang Jiao could do some magic. Therefore, when the military doctors failed to diagnose and cure the disease, Liu Bei was willing to let Zhang Ning give it a try just in case.

Okay.

And Li Mengxi was willing to eat wildly with willow branches because he knew that he would not die from eating, and he could not live up to the kindness of others, so there was no harm in eating some.

As time passed, Li Mengxi ate a lot of willow branches, probably a handful, which made him feel sick.

Putting down the last half-eaten branch, Li Mengxi said to Zhang Ning in embarrassment, "Sister Ning, I can't eat anymore. I won't eat anymore."

Li Mengxi had already eaten so much that the corners of his mouth turned green, and Zhang Ning secretly smiled.

——

The next day, when Li Mengxi got up early in the morning, he clearly felt that his headache was gone and he was no longer dizzy.

It's much better than the previous two or three days.

Li Mengxi reached out and touched his head. His forehead was no longer hot, and Li Mengxi breathed a sigh of relief.

It looks like he's getting better and won't die from the cold.

My condition is much better. Except for the vague pain in my head, my body feels much better.

When we went to the city lord's palace early in the morning, Liu Bei and others were there. At the first glance, everyone asked if they were okay.

After asking, looking at Li Mengxi's face again, Liu Bei smiled and said, "You look much better today."

Li Mengxi also nodded, "I feel better."

Jian Yong joked from the side, "It seems that the girl's medical skills yesterday were really good, and the medicine can cure the disease."

Li Mengxi looked at Jian Yong, who had a bright smile on his face, and returned, "No, Zhang Ning didn't even take the medicine. What he brought me was a bowl of talisman water. Tsk, Zhang Jiao..."

As he spoke, Li Mengxi suddenly stopped.

He felt extremely strange. One day ago, his health was very poor and his condition was very bad. However, it seemed that after drinking the talisman water given by Zhang Ning, he could sleep well when he went back to sleep, and when he woke up, he was in great condition.

Thinking back on it, Li Mengxi found it unbelievable. Is the talisman water really capable of curing diseases and saving people? A bowl of water, a talisman, and some willow branches, can it really cure diseases? Is there really such a thing as a strange power that confuses the gods?

However, something doesn't seem right. It's not like I've never seen Zhang Jue before. Zhang Jue is just an ordinary person. He doesn't have the ability to control the wind and rain.

Therefore, it was probably not some mysterious power. Li Mengxi guessed that the medicine prescribed by Tian Bu might be effective. Although he had taken the medicine for several days, his condition had not improved, but it was probably because he was not full after eating four bowls of rice.

After five bowls, I was full in no time.

The amount reached has changed.

But after thinking about it more carefully, Li Mengxi felt that something was not right. His condition was still very bad one day ago, but after drinking the Talisman Water, his condition immediately improved in just one day. If it was all due to the Tianbu herbal medicine, I am afraid it was not entirely true.

With this speculation, Li Mengxi suspected that the talisman water really had an effect.

Li Mengxi didn't believe in witchcraft such as drawing talismans to apply water. Drawing a talisman could have some effect, so it was definitely not a problem with the talisman.

The water Zhang Ning gave was a bowl of clear water, a talisman and a handful of willow branches in the water.

It's not the talisman, it's definitely not the bowl, and it's definitely not the water. If the water was useful, I would have been cured long ago after drinking so much boiled water in the past few days.

The only possibility left is the willow branch.

Li Mengxi frowned, what use can the willow branches have? Willow branches are so bitter... Yes, good medicine tastes bitter. It seems that most bitter plants have medicinal value.

Doesn’t the key lie in the willow branches?

Li Mengxi then thought that there was also a willow branch inserted in the glass vase of Guanyin Bodhisattva. When he made the connection, Li Mengxi thought that it was most likely that the willow branch was really a good medicine. It was a super magical medicine that could cure headaches and brain fever.

Li Mengxi was very curious, what exactly was the medicine in the willow branches?

The experience of making paper some time ago is still fresh in my mind. When I was making paper, I didn't know what could decompose plant fibers, so I tried a lot of oils, alcohols, acids and alkalis, but the result was really found.

Based on his previous experience, Li Mengxi thought that he might try to extract interesting things from willow branches. Eating dry willow branches would be too unpalatable.

When it comes to extraction, according to the knowledge you have learned, the method of extracting substances can make use of the solubility properties of the substances. Some substances are soluble in water, some are insoluble in water, some are easily soluble in grease, some are insoluble in grease, and some are soluble.

In alcohol, some are insoluble in alcohol.

Water solubility, fat solubility, alkali solubility, acid solubility, and alcohol, it should be alcohol solubility. There are only so many common solubilities of substances. Relying on acid, alkali, lipid, water and alcohol, 90% of substances can be distinguished.

come out.

So, there is a plan.

Soak willow branches in acid, alkali, grease, alcohol, water, and all kinds of things.

Then, find a patient with a headache and fever, and feed the patient with willow branch water soaked in various acid-base, oil, and alcohol to see which solution will be effective. This can directly test the solubility of the medicine in the willow branch that can cure the disease.
