In this chapter, Ren tells us that he's 15 years old and still hasn't awakened his bloodline. He's a martial god in his previous life, so he knows how to master martial arts. But he still doesn't have a strong enough bloodline to be a powerful martial artist. He explains that talent, comprehension, and aptitude are the three most important things a martial artist needs to master. The previous owner of the body opened seven gates to the human level, but the aura pool isn't strong enough to support a strong martial artist like Ren. This means that if Ren continues to cultivate, he won't be able to reach his previous level.
