After Cao Cao finished speaking, the leader first raised his hands toward the city wall, and then rode his horse closer to the queue.

Not long after, a familiar figure jumped out of the carriage behind the queue.

"A certain Zhao Yun, please see Mr. Xi!"

On top of the city wall, the moment he saw Zhao Yun appear, Xi Yu's face clearly showed a bit of surprise.

Zhao Yun is here?

Didn't he just return Zhao Yun to Liu Bei's camp last time?

How could the other party appear outside Juancheng at this time, and there are hundreds of Xiangyong.

There are about a hundred or ten people riding horses under the city at a glance, and in this situation, these people are obviously headed by Zhao Yun.

As Zhao Yun asked for a meeting.

Cao Cao next to him also had a puzzled look on his face. He also remembered that Xi Yu had let him go not long ago, so why did he come here again?

However, seeing Zhao Yun appear at this moment, Xi Yu was in a good mood.

"Zilong, wait a minute, I'm coming!"

After glancing at Cao Cao, Xi Yu leaned out from the city wall and shouted to Zhao Yun, then led Dian Wei down the city wall.

Not long after, Xi Yu led Zhao Yun and his party into the Juancheng gate.

"Yun, I have met Mr.!"

Seeing Xi Yu again, Zhao Yun felt quite emotional. He had come all the way, claiming the name of Xi Yu, and there was no obstacle in Yanzhou.

Compared to when I returned to Xiapi and was shouted at by Zhang Fei.

There is a world of difference between the two.

This treatment made his heart feel warm.

Xi Yu stretched out his hand to support Zhao Yun, who was bowing to him. Although he was a little surprised, he couldn't help but ask with concern.

"Zilong, didn't you just return to camp last time? What is this now?"

"Sir, it's a long story!"

Immediately, Zhao Yun quickly told the story of his return to Liu Bei's camp, and then said that he had returned to his hometown.

"I never thought that Liu Xuande would be so unwise!"

After hearing Zhao Yun's story, Cao Cao beside him was also a little emotional. A strong general like Zhao Yun was suspected after returning.

Liu Bei was actually able to do such a thing, which really surprised him.

Zhao Yun explained that it was not because Liu Bei was suspicious, but Liu, Guan, and Zhang were three brothers after all. If one person did some things, they should carry them together.

Cao Cao was a little excited. Looking at Zhao Yun's posture, it was obvious that the other party was rushing to join him.

It is a great joy to bring along a group of local braves!

Zhao Yun is also a powerful general no less than Dian Wei!

Xi Yu listened carefully and glanced at the carriage behind Zhao Yun.

"Zilong, is that your brother in the car?"

"That's right!"

Upon hearing Xi Yu's question, Zhao Yun nodded quickly and then looked quite grateful.

"If it hadn't been for my husband's words in the previous episode, I would have almost lost my brother!"

"After Zi Yun returned to Changshan, he learned that his brother was in critical condition. Previously, my husband said that he could save brother Yun. Yun did not dare to delay, so he brought Xiang Yong to visit him!"

Zhao Yun didn't say anything about surrendering, but Xi Yu didn't ask any questions.

He will not repay a favor. Since he has promised Zhao Yun before that he can come to him, and now that the other party comes to him, he will naturally not refuse.

Knowing that the other party's brother was seriously ill, Xi Yu naturally did not delay at all.

"Take your brother to my house!"

After saying something to Zhao Yun, Xi Yu turned to look at Dian Wei: "Awei, help settle the Xiang Yong brought by Brother Zilong!"

After the words fell, Xi Yu looked at Cao Cao again.

The latter nodded: "I'm going to do it, I'm planning to take Meng Zhuo back!"

……

After everyone separated, Xi Yu quickly took Zhao Yun and his brother back to the Xi family's residence.

After vacating a house, Xi Yu helped Zhao Yun settle his brother down, and after a casual inspection, he understood.

Zhao Yun's brother has indeed contracted pneumonia, and his current situation seems to be extremely serious.

Seeing the worried look on Zhao Yun's face, Xi Yu reached out and patted Zhao Yun's shoulder gently.

"Don't worry, I already know your brother's illness and I have a sense of proportion!"

Now that it is confirmed to be pneumonia, we only need to find a way to extract penicillin.

Brother Zhao Yun's illness seems serious at the moment, but it is not fatal, so it is not a problem to survive for a while.

After thinking about it, he gave instructions to Zhao Yun, and Xi Yu hurriedly planned to extract penicillin himself.

In this era, there is no such thing as chemical synthesis. If you want to extract usable penicillin, you can only use local methods.

It’s not difficult at all. You just need to find rotten fruits and vegetables and process them to get penicillin.

After figuring it out, Xiyu asked people to collect rotten fruits and vegetables.

Although it was winter, it was not difficult for Xi Yu to collect things throughout Juancheng with great fanfare.

In less than two days, Xi Yu collected a lot of rotten fruits and vegetables.

Naturally, this situation is somewhat confusing to outsiders.

Although Zhao Yun is a little confused, Xi Yu has already promised, and he trusts him very much.

It's actually his brother's illness. He has taken him to see many doctors, and now he doesn't have much else to do.

"What does Fengyi do with these rotten fruits and vegetables?"

When Xi Yu was collecting rotten things throughout Juancheng, Cao Cao naturally got wind of it, and many of them were obtained with his help.

Cao Cao was naturally curious about what Xi Yu was doing.

After all, the other party has done many shocking things before.

Cao Cao was minding his own business and came to watch with his men, but Xi Yu ignored him.

Although the technology of the times is somewhat backward, with a large amount of manpower, many things can be supplemented.

There are quite a few moldy fruits and vegetables. After carefully selecting them, Xi Yu selected the ones containing penicillin.

After some treatment, he got penicillin that was barely usable.

"Sir, this is the hose and needle you want to make."

After receiving the simple needles and hoses prepared by Ma San and others, for Xi Yu, all the preparations were almost done.

Outside the actor's house, in the courtyard at that time, Cao Cao and others were gathered outside the courtyard, and Zhao Yun was also among them.

"Sir, can these things really save my brother?"

Over the past few days, Zhao Yun was a little confused by Xi Yu's actions, and naturally Cao Cao and others were also confused.

"If you can't explain it in one or two sentences, just watch it!"

Xiyu doesn’t have much explanation.

He has already prepared physiological saline and water bags. He only needs to inject a small amount of penicillin into the patient. It is expected that the patient's pneumonia will be relieved.

Xi Yu knows very well that penicillin is a miracle drug for this era.

After some processing, Xi Yu successfully injected penicillin into the patient's body.

With the effect of penicillin, the patient's face, which was still coughing from time to time, has significantly softened.

Seeing this scene, Zhao Yun couldn't help but feel a little excited.

Immediately afterwards, he bowed down to Xi Yu in front of everyone.

"Yun thanked Mr. Yun for his kindness in saving his brother. There is no way he can repay this kindness. In the future, Yun Yuan will lead his horse and kick the pedal for him!"

Before looking for Xi Yu, Zhao Yun discussed it with his brother.

Regardless of whether Xi Yu can save his brother, Zhao Yun plans to join Xi Yu.

The experience with Liu Bei really chilled Zhao Yun, and after hearing Zhao Yun's thoughts, his brother also strongly agreed with Zhao Yun's choice.

Now that he is watching his brother's recovery, Zhao Yun naturally joins Xi Yu without hesitation.

This move immediately made Cao Cao present a little dumbfounded.

After Zhao Yun arrived in Juancheng, he felt a little hot in his heart.
