Cheng Xuan sat up, looked at Old Man Cheng, and said with a guilty tone, "Grandpa, it's all my fault. I always make you worry. It's all my fault for having an accident in the middle of the night, making you carry me so far to beg for a doctor. I'm an unfilial grandson, it's my fault."

He was in poor health from birth. His grandfather set up a stall every day to earn money for his medical expenses. He would get up in the middle of the night to prepare ingredients and stand on the street all day long, and he would also be extorted by street thugs from time to time.

If he hadn't gone to see his grandfather and witnessed it with his own eyes, he wouldn't have known how much his grandfather had sacrificed for him.

Once, during a festival, all the pastries Grandpa made were sold out. A family came to buy pastries, but when they found out that Grandpa's pastries were sold out, they immediately ordered the servant to smash the blanket. Grandpa was injured and had to lie in bed for half a month.

He told his grandfather that he wanted to be as powerful as his father, to fight the enemy and defend the country. When his grandfather heard this, his eyes filled with tears, and he remained silent for a long time. Finally, he sighed and specially saved up money to hire a master to teach him martial arts.

Old Man Cheng affectionately patted Cheng Xuan's head and said, "Good child, it's only right for Grandpa to take care of you. Is there anything else that's bothering you? If so, please tell me."

Doctor Xu came over and examined Cheng Xuan again. He was very surprised. If he took the medicine for a while longer, he would be completely cured.

If you continue to consume those pills, your physical condition will definitely be excellent in the future.

"Dr. Xu, how is Xuan'er?" Old Man Cheng couldn't help but ask when he saw that Dr. Xu hadn't spoken for a long time.

"That's good. He should be fully recovered in a while," Dr. Xu nodded.

Upon hearing this, Old Man Cheng finally felt relieved. "Thank you, Dr. Xu. Oh, by the way, this is the medical expenses over the years. I am deeply grateful for Dr. Xu's great kindness."

When Doctor Xu saw Old Man Cheng take out ten taels of silver from his pocket, he was somewhat shocked. "Where did you get this money?"

As far as he knew, the old man not only wanted to treat his grandson's illness, but also hired a martial arts instructor for him to learn martial arts. Because his family was the orphan of a general, he took care of him without accepting any money from his family.

Old Man Cheng said with a grateful expression, "It was that benefactor from yesterday. He even gave me his money pouch earlier, which attracted the attention of others and almost got robbed by bad guys. Later, thanks to his help, I got the money back. Fearing that it would attract others to steal, he gave me some loose silver. But even that small amount of silver was a lot. He is truly a very kind person. I didn't expect that last night, he would send someone to give me more silver... That's why I have the money to pay off the medical bills I've owed for so many years. You are just like him. What have I done to deserve this?"

Old Man Cheng's voice choked as he spoke, while Doctor Xu looked on in surprise.

It turns out that the Emperor and Old Man Cheng knew each other long ago. The Emperor gave all the money to Old Man Cheng, probably because he knew that Old Man Cheng had a son who died in battle.

well……

Doctor Xu waved his hand, refusing the money. This was money given by the Emperor; he dared not accept it.

Besides...

"I already said I wouldn't take your money, so I'll keep my word. Take the money back and buy Cheng Xuan some good food to nourish his body. Just don't let the child suffer."

"No, no, your medicine also has costs. Besides, you went to a distant place to collect herbs for Cheng Xuan, and you even used ginseng in the medicine. I don't know much about other medicines, but ginseng is very expensive. Even if I give you all this money, it won't be enough. But I'm happy to pay you some money. I'll earn the rest slowly." Old Man Cheng shook his head repeatedly, urging Doctor Xu to accept the money.

Dr. Xu sighed, “Why are you so stubborn? Cheng Xuan should be sent to school. This child has come to help me a lot these past few years, always calling me Grandpa Xu. It makes me feel much better. Why don’t we do this? I have no descendants anyway, and I like this child very much. Why don’t I become his godfather? In the future, he will be my grandson. This money can be used for his schooling.”

Old Man Cheng was stunned for a moment, "This... Doctor Xu, how can this be... my grandson, he..."

Doctor Xu nodded, "Of course you can, why not? I've watched Cheng Xuan grow up, why can't he be my grandson? What? Do you think I'm not worthy to be Cheng Xuan's grandfather?"

"No, no, no, how could that be? You being his grandfather is wonderful, you..."

As soon as Old Man Cheng finished speaking, he turned to Cheng Xuan and said, "Xuan'er, hurry up and come over and kowtow to your Grandpa Xu. If it weren't for your Grandpa Xu, you wouldn't be able to wait for the miracle doctor to save you now."

Cheng Xuan obediently got out of bed, but was stopped by Grandpa Xu. "The child is weak. Why make him get up? Lie down, lie down and rest well. I'll hold a banquet to let everyone know when you're better."

Upon hearing Doctor Xu's words, Cheng Xuan was at a loss for what to do. He could only look to his grandfather for help.

"Since your Grandpa Xu wants you to lie down, then you should. But don't forget, you'll have to take care of Grandpa Xu in his old age and see him off when he passes away, understand?"

"Yes, Grandpa, I've written it down."

"Okay, good boy, lie down properly." Grandpa Xu quickly came over and happily watched Cheng Xuan lie down.

The thought that I have a successor, even if he can't learn medicine from me, at least I have a grandson, makes me happy and excited.

Old Man Cheng still handed the money to Doctor Xu, saying, "Doctor Xu, please keep this money. Everyone knows you've always done good deeds in this town. Even if you had mountains of gold and silver, you couldn't afford to spend it like this. Please accept it; consider it my contribution to charity. Is that alright?"

"this……"

"Oh, forget about this and that. Just keep this money safe and use it to buy medicine for the people. What, does it mean you're the only one who can do good deeds? Can't this old man do some good deeds?"
