Douluo: the Strongest Douluo of Destruction

This book gave me a very uncomfortable feeling when I read it

The final evolution of the Sharingan is the Rinnegan. There is no need to write another Rinnegan.

It is enough to have a stronger martial spirit, there is no need to write so many bells and whistles about martial arts

Why do you need the Sharingan when you can directly use the Rinnegan?

Author, I would like to ask, where is the protagonist's Sharingan? Why hasn't the Sharingan awakened?

You're not writing about Naruto. Don't care so much.

Author: I feel an inexplicable feeling when I see being cheated on. Can we let the protagonist travel back in time in the later stage? Beat that woman up, because every time I see this kind of plot, I always feel that once there are more women, I always feel bad. When I read novels about that, I always read them crookedly. So, you know, by the way, there are also comics.

Author, I want to say one thing. When the Sharingan evolves into the Rinnegan Eye, the main thing missing is Indra Chakra and Asura Takhara. As long as you have these two chakras, you can evolve into the Rinnegan Eye. Not only Hashirama cells can evolve into the Rinnegan Eye. There must be some Uchiha people who have transplanted Hashirama cells, but they have not succeeded, and there is no Indra Chakra. Uchiha Madara can evolve into the Rinnegan eye because he has Indra Chakra himself and transplants Hashirama cells.
