First of all, I would like to thank those classmates.
Secondly, regarding Tongtian Pill, I really forgot about it. When I wrote it yesterday, I recalled it seriously, and then I found that recall is really the most unreliable thing.
Thanks to the students who pointed it out, I apologize and will make corrections.
Finally, it is really painful to write a different and awesome plot, especially when your abilities are not particularly strong.
