Dedicate science to a better world

Chapter 99
Thanks to the love of all book friends, this book is finally going to Sanjiang. As an author, it is the first time for me to get such an opportunity. Of course, I am very happy

Originally, this should have been posted yesterday, but today I found out that there is no 6st in June. So I would like to thank the national book friends for their rewards. I can only say that it is a coincidence, and I can’t see me adding more immediately.
