After getting out of the carriage, Yun Xiuqing and Pu weicang walk into the livestock market. Yun Xiuqing follows the pig's cry and finds a pig seller. The pigs are black and white, and they are all piglets.

Yun Xiuqing didn't know what to look at when he bought a pig, so he hit Pu weicang with his elbow: "Pu weicang, which pig do you think is better here?"

Puweicang frowned and whispered to yunxiuqing, "I haven't raised a pig, but I've seen wild boars in the mountains. Their eyes are bright, their calls are loud, and their tails swing freely. It's good for us to look like this."

Yun Xiuqing nodded, squatted down and looked at the litter of pigs. When the pig seller saw that Yun Xiuqing and Pu weicang were interested in buying his pigs, he quickly said, "girl, young master, my pig is from the south. You don't think it's small at this time, but look at the ruddy skin. In a few days, it will grow fierce, and it's not expensive. A pig is always copper."

"This is a litter of pigs?" Yun Xiuqing asked with an eyebrow.

"It's definitely a litter of pigs, girl. I don't cheat. I sell pigs here all the year round. If there is any problem, you should come to me." The pig seller patted his chest.

Yun Xiuqing didn't hear the words of selling pigs. If she bought them back, she would die. The pig seller would say that she would not raise pigs and feed the wrong things.

There are 13 pigs in this litter. Yun Xiuqing chose the biggest boar in it. Although she doesn't know what pigs are good for, she also knows that in a litter, the biggest one must eat the most. If she can eat more in so many pigs, she must have a good constitution.

Yun Xiuqing didn't want to haggle with the pig seller, so she gave him a copper plate and bought the boar.

The pig seller saw that Yun Xiuqing was so generous and gave her a basket for free.

Yun Xiuqing put the pig into the basket. Just as he was carrying it on his back, Pu weicang suddenly took it over and carried it on his back.

Yun Xiuqing only felt light on his body. When he looked up, he saw Pu weicang carrying the basket behind him as usual.

"Don't you want to buy two pigs?" Pu weicang was afraid that Yun Xiuqing would refuse him, so he quickly changed the topic.

"I'll go to another house and buy a mother's one later." Yun Xiuqing's attention was immediately diverted by Pu weicang's words

"why do you want to buy another one?" Pu weicang was very confused.

After listening to Pu weicang's question, Yun Xiuqing remembered that he did not know the importance of inbreeding in ancient times: "let me tell you this, if the elder brother and younger sister born by his mother marry, 80% of the children born by them are deformed, and vice versa, so are pigs."

Pu weicang listened to Yun Xiuqing's answer, still very confused: "what is deformity?"

Yun Xiuqing choked on Pu weicang's question and patiently explained to Pu weicang: "the so-called deformity is that a child is born sick, lacking arms and legs, or deaf and blind. I tell you, half parents, cousins and cousins can't do it, unless there are three generations apart."

Pu weicang suddenly felt as if he had discovered a secret. He seemed to remember that the former Emperor and the former queen were cousins, and they were not separated by a generation. They gave birth to three princes. They were all ill and died in a month. Then two years later, the former queen gave birth to a fourth prince, and this prince has nothing to do now.

Pu weicang thought more and more, he was more and more frightened. He did not dare to think any more.

"Yun Xiuqing, don't tell anyone about this." Pu weicang frowned to remind Yun Xiuqing.

Yun Xiuqing nodded her head. She knew that in ancient times most of the rich official families were cousins or cousins, which involved many private matters. If it was spread out, she didn't know how to die.

At this time, Yun Xiuqing met a pig seller. The pigs in this family were all white and had no pattern. Yun Xiuqing chose a sow and still had the same money as last time.

After buying another pair of pigs, Yun Xiuqing and Pu weicang returned to the carriage with a pig in their hands.
