Mu Enqing comforted Tang San, saying, "Don't worry, the teachers just want to check your body to see where your Demon God Transformation has mutated so that we can tailor our teaching in the future to better develop your abilities."
Indeed, after the two battles Tang San participated in today, the teachers almost unanimously agreed that his Demon God Transformation must have mutated. If the Demon God Transformation weren't mutated, how could he possibly have displayed such formidable strength? This was a violation of common sense.
But the specifics of the mutation were very important. For humans, research on the Demon God Transformation was ongoing. Especially for someone like Tang San who was able to show such strength at a young age, it was extremely rare. How could they let such an opportunity slip by?
