They are mother and son.

He pondered for a while, and an idea came to him.

He then asked Xiao Qingyin, "Do you have that kind of medicine? It makes people look like they're dead, but they can still move around at any time."

Isn't this just a fake death drug?

Xiao Qingyin raised an eyebrow.

What do you need this medicine for?

Wei Zhenghong replied, "There are some things I'd like to understand."

Xiao Qingyin immediately understood that he wanted to use a trick against her, so she sold him the medicine.

Before leaving, Wei Zhenghong instructed, "Please keep my visit to see you for treatment tonight a secret."

"OK."

After returning to his residence, Wei Zhenghong dismissed the guards outside the door, took a drug to feign death, lay down on the bed, and waited to see what would happen.

In the middle of the night, the servant who brought him medicine pushed open the door, checked his breathing, and seeing that he was not breathing, immediately turned and left.

A short while later, the old lady and Aunt Chang came in.

After checking his breathing and pulse, Aunt Chang said to the old lady, "He's really gone."

The old lady breathed a sigh of relief and comforted her, "You've suffered so much these past years. If that old fellow hadn't looked down on the Chang family and insisted on marrying into the Ning family, you wouldn't have had to swallow your pride for so many years."

Aunt Chang did not speak.

"You're not going to regret this, are you?"

The old lady asked.

“He was so ill, he didn’t have many days left to live. We helped him end his suffering early and let him pass away peacefully. He should thank us.”

Aunt Chang shook her head: "I don't regret it. I'm just a little sad that he left so early."

"There's no need for that," the old lady sneered. "He took such a huge advantage of our Wei family and lived a life of luxury for most of his life. He deserved to die."
