Fights Break Sphere: Season 1 (2018)

Main chacter transfarred from another universe
-Just like Douluo Dalu there is ranking system among martial artists where you can level up by usual training or by finding certain ojects(Essence flowers vs Halos)
-Just like Douluo Dalu main caharacter is coming from a fallen clan and making most power clans on continent his enemy

If you loved reading either of these mahwas you should certainly read other one.

These are very similar with little difference including the beginning and the current plot. They both have the main protagonist who was reborn to a new world which seems to have a sort a like rpg system in which they are ranked on their strength.
for example in doulou dalu there are levels as well stages = 0 - 10 (spirit scholar) 11- 20 (spirit master) and so on, it's similar in fights break sphere as well.
Both protagonist meets someone who now they considers master in which leads them in the new world as well massively increasing their strengths. the current story shows them venturing with their masters and getting stronger while helping others along the way.

If you enjoy a story of someone reborn to a new world with amazing talents to be considered a genius or "Monster" you'll love these both, however in douluo it shows the main protagonist using his knowledge of the old world while it doesn't really show or tell you in fight break sphere that he was reborn but at the beginning.
