At the beginning, his wife came to him, and he became rich by selling kidney treasures.

"Since you said so, you have to be patient."

"This will be very painful." Ren Hao continued.

"It doesn't matter if I endure it, but before that, can you give me a pot of good Maozi wine?"

"When I was at the God of War Pass, I tasted this kind of fine wine from Generals Chen Fei, Zhang Kuai, and Wu Chu." Xu Qing suddenly chuckled, revealing the real purpose of his visit to Ren Hao.

"You really are such a fool." Ren Hao shook his head speechlessly. His life was almost in danger and he was still thinking about drinking.

But Ren Hao still helped Xu Qing and asked Qingzhu to send a whole jar of Maozi.

Of course, this Maozi is not only for Xu Qing to drink, he also has other needs.

You have to know that there was no alcohol in that era, and disinfection depended entirely on incense or medicine.

However, this disinfection ability is far inferior to that of alcohol.

Although Ren Hao doesn't have alcohol now, these distilled Maozi can barely serve as a substitute.

Ren Hao used a gourd ladle to scoop a ladle of grass seeds from the jar, poured it into the pottery pot, and started roasting it over a fire.

When the grass in the pot was almost boiling, Ren Hao took the pot down.

"Brother Wu, I'm going to disinfect you now, please bear with it for now." Ren Hao walked up to him holding a clay jar and warned him.

"Come on, don't worry. I can handle it." Xu Qing nodded and drank the Maozi in the bowl.

Then, Ren Hao poured the boiling grass directly on Xu Qing's wound.

"Fuck!!!"

This hurt Xu Qing so much that he blurted out a curse word and subconsciously kicked over the table in front of him. He had no place to put his hands, so he grabbed the legs of the stool next to him.

But even so, it was still unbearable. Xu Qing kept gritting his teeth in pain and even shed tears.

The purity of this thatch has not yet reached the level of alcohol. If alcohol were really produced, Xu Qing would probably be in so much pain that he would cry for his parents.

Ren Hao glanced at Qingzhu, who was standing at the door looking almost dumbfounded, and ordered, "Qingzhu, go find a wooden stick and bring a bottle of golden wound medicine."

"Oh, yes sir."

Qingzhu took several seconds to react and went out to get a wooden stick for Ren Hao.

"Master, what do you want this stick for?" Qingzhu handed the stick to Ren Hao in confusion.

"Of course it's for physical anesthesia." Ren Hao took the stick, not caring whether Qingzhu could understand it or not. He took advantage of Xu Qing's lack of reaction and hit Xu Qing on the back of the head with the stick.

Xu Qing rolled his eyes and fainted on the spot.

After giving Xu Qing physical anesthesia, Ren Hao took the small knife used for cutting meat, dipped it in grass seeds, and baked it back and forth over the fire to disinfect it.

After disinfecting the knife, Ren Hao started to cut off all the necrotic flesh in the wound piece by piece.

This process was also very long, taking almost an hour until the upper arm bones were seen.

Because Xu Qing missed the best time for treatment, the rust poison had already invaded the bones and turned black.

Fortunately, the spread of the rust is not very serious and it can be saved as long as the rust is scraped off.

Just when Ren Hao was about to cut, Xu Qing woke up slowly.

The severe pain coming from his arm made Xu Qing grimace: "My...my...my arm, why...why does it hurt so much."

"The pain is still to come, just bear with it for now." Ren Hao turned the wooden stick horizontally and let Xu Qing bite it.

Then he started to use the knife to scrape Xu Qing's bones and heal his wounds.

With every blow from Ren Hao, Xu Qing's whole body twitched violently in pain, but he didn't utter a single sound and just held the stick tightly.

About half an hour later, Ren Hao scraped off the last bit of black rust from Xu Qing, and then used thatch to remove the poison from Xu Qing. Xu Qing fainted from the pain.

Ren Hao then applied some golden wound medicine to Xu Qing to stop the bleeding, and then bandaged the wound with sterilized linen.

After doing all this, Ren Hao was so tired that he almost collapsed and sat down on the ground to rest.

But before he could catch his breath, Xu Yating came into the room.

When she saw her second brother lying unconscious on the ground and Ren Hao's hands and the ground were covered in blood, her first reaction was a blank, and then she imagined some messed up plots.

In the end, Ren Hao accidentally killed Xu Qing.

"This……"

Ren Hao and Xu Yating looked at each other for a few seconds.

Then Xu Yating came to her senses. Her first reaction was not to ask Ren Hao what he had done to her second brother, but to grab Ren Hao and tell him to run away quickly.

Not to mention that Xu Qing's father is a military commander, his identity as a young marquis is enough to kill Ren Hao.

"Husband, you...you should take Sister Wan'er and run away first. I will stay in the mansion to buy time for you." Xu Yating said hurriedly.

"Why are you running? Where are you running to?" Ren Hao didn't react for a moment.

"It doesn't matter where you run to, as long as you don't stay in the Central Plains."

"You killed my second brother. Even if His Majesty is willing to forgive you, my second uncle will definitely not let it go." Xu Yating said hurriedly, not realizing that Xu Qing was not dead.

"Who said I killed your second brother? Don't talk nonsense." Ren Hao was speechless for a while. He didn't know what strange plot Xu Yating had imagined just now.

"what?"

"You didn't kill my second brother, so why is there so much blood?" Xu Yating pointed at the bloodstains on the ground, wanting an explanation.

"I'm scraping your second brother's bones to heal his wound. There will definitely be blood."

"If you don't believe me, you can try your second brother's breath to see if he is still breathing." Ren Hao pointed at Xu Qing who was unconscious on the ground.

Xu Yating immediately put her hand in front of Xu Qing's nose, and after confirming that Xu Qing was still breathing, she finally put her heart at ease.

Then, she went up to him, raised her fist, and punched Ren Hao on the chest a few times, saying, "Husband, why didn't you tell me earlier? I was worried for nothing. I thought you really killed my second brother."

"You can't blame me for this. It's you who made up such a mess in your mind." Ren Hao shrugged helplessly, then carried Xu Qing to the guest room.

On the way to fight Xu Qing, Xu Yating asked Ren Hao: "Husband, did my second brother make things difficult for you when he came?"

After all, in order to marry Ren Hao, she severed all ties with the Xu family, which made her family very angry.

"Why is it so difficult? I have a good relationship with your second brother, you don't have to worry." Ren Hao explained casually, without mentioning that when Xu Qing came, he didn't ask about her affairs.
