Xu Rao was relieved to hear this and arranged for someone to help Wu Muyue wash up before he went with Chen Zhaoci to the courtyard where Xu Bai lived.

Xu Bai and Chen Yuyuan lived in the largest courtyard in the front yard. The main house in this courtyard had four rooms, which was just enough for the two children to each have two rooms. As for the side rooms, they were used by the guards who came with Chen Yuyuan.

When the two arrived, they saw Xu Bai and Chen Yuyuan sitting at an eight-immortal table behind a screen in the main room, with a lot of messy things on the table.

Seeing Xu Rao and Chen Zhaoci enter, the two quickly stood up. Xu Rao looked at the things on the table, smiled and shook his head, saying, "Brother Bai, are all these things yours?"

Xu Bai chuckled and said, "Dad, look, I figured all of this out myself. Look at this, a lime packet. I even added some chili powder inside. It works like crazy, a must-have for home and travel. This is called Rainstorm Pear Blossom Needle. You see, press here, and it'll turn the person on the other side into a hedgehog. But you can't use it carelessly, or you might accidentally hurt them."

Chen Zhaoci sighed and said, "Child, you've already learned your skills from your masters and can defeat those demons and monsters. Is it really worth it for you to rack your brains to do these things?"

Xu Bai said, “Mother, you don’t understand. No matter how hard I practice, there will always be someone better than me. Once I’ve mastered these things, or even created something more powerful, even if someone’s kung fu is better than mine, can they still be defeated by me? Sometimes, a contest is not just a contest of physical strength, but also a contest of ability.”

Chen Zhaoci picked up the lime bag and squeezed it, saying, "You're carrying this lime powder in a small cloth bag. Would you dare to keep it in your pocket after a rain shower?"

Xu Bai said, "So I'm thinking about how to make thin and easy-to-use oilcloth, and rubber. My third uncle said he has already found rubber trees for me in Qionghai, so I might actually be able to make them."

Chen Zhaoci always felt the most pity and tolerance for her youngest son.

As for Xu Zhi, since Xu Zhi was a native of ancient times, Chen Zhaoci asked Granny Lu to teach her some important ideas, so that Xu Zhi could understand everything about this era and live better in this world.

As for Xu Di and Xu Bai, they have already been educated with the ideas of the new era. Even if they were to be further influenced by the ideas of this era, they would not change their thinking.

Xu Rao and Chen Zhaoci understood very well that at their age, they would soon be able to hold their grandchildren. After gaining experience outside for a few more years, Xu Rao would be transferred to the capital. As for their two sons, what path they would take in the future and how they would walk that path would be their own business.

Not only Xu Rao understood, but Chen Zhaoci also understood very well how important a person's thoughts are to that person. Xu Di was alright, after all, he had already integrated well into this world and allowed his thoughts to gradually integrate into this world. Of course, there were many things that were so incompatible with his former world, but Xu Di always managed to find a way to adapt to this world.

Xu Bai, on the other hand, has not truly entered society. Everything he has learned is from school. Although he is a person with very positive values ​​and advanced thinking, this world will not treat you kindly just because you have these two things. Only by adapting your thinking to this world can you live well in this era. This is also the reason why Xu Rao wanted Wu Muyue to be Xu Bai's teacher.

Ordinary school teachers would only make Xu Bai resent everything they taught him, making him even more unwilling to accept everything that this era had given him. As for Wu Muyue, putting aside his knowledge, he could always quickly accept some more advanced things. Even if it was some unconventional ideas, Xu Rao believed that Wu Muyue would not completely deny them after hearing them, but would carefully consider whether they could be explained and whether they were reasonable.

When Xu Bai mentioned rubber, Xu Rao's eyes lit up, and he asked, "Brother Bai, did your third uncle really tell you he found rubber?"

Xu Bai said, "Last time, when my third uncle wrote to my eldest brother, he said that he had found some rubber trees in Qionghai that my eldest brother had mentioned to him. My third uncle also said that when my sister goes there, he will take her to see them."

Chen Zhaoci overheard Zhang Zhaozhi saying he was taking Xu Zhi to Qionghai, which is probably what later became Hainan.
