Under one person: If I let you refine your Qi, will you become an immortal?

Update announcement to explain the situation

I wanted to resume updating yesterday and finish writing it in one go, after all, it was only the last 100,000 words.

But after writing for a day, my physical condition was still too poor.

My back and waist ached after sitting for a while, and I was really scared by the uncontrollable shaking of my body before.

So I should update irregularly in the future, and try to finish this book from beginning to end. After all, this book is the author's hard work for nearly a year. In addition, thank you all for your continued support.
