As for martial arts techniques, there were no hard and fast rules.
In fact, this didn't really affect Lin Yi at all. The so-called body strengthening poison techniques didn't exist in the first place, and banning it made things a lot easier for Lin Yi. He didn't even need to find an excuse to explain why he didn't use it.
From now on, in the sect's internal tests and competitions, as long as he followed the rules and used the jianchun sect's skills, no one would suspect why Lin Yi didn't use the body tempering poison technique.
Lin Yi only needed to have a rough idea of the rules-body strengthening techniques were still his main interest, so he quickly flipped to the section and started studying.
After a short while, Lin Yi roughly read through the chapter. It was good to have a strong essence spirit-he only had to read it once and he basically remembered it all!
