Is the D-Class Template Weak? Have You Ever Heard of One Punch Man?

I traveled through time and became the young master of a big family with a spiritual power of 300 points! The higher the mental power, the greater the chance of awakening the S-class template! Even SS-level templates, SSS-level templates are possible! Bai Mu raised his head and walked up to the template awakening circle. Under the attention of everyone, he awakened the most rubbish D-level template. "The eldest young master of the Bai family has 300 points of mental strength. That's it?" "Pfft... D-level template? My sons are all C-level." "The young master of a big family is nothing more than that." "…" Awakening the D-class template, the engagement was broken off by his fiancée, and he was expelled from the family... In one day, Bai Mu fell from the clouds to the bottom of the valley. However, the D-class template is correct, but what the hell is this bald head? Isn't this Saitama from "One Punch Man"? Bai Mu trained day after day, and slowly, no matter what happened, if he could solve it with one punch, he would never use a second punch! "Brother, you are my brother! Can you slow down when you run in the forest? I have been broken by you three times this month!" A certain demon king cried bitterly. "Is this... Is this still a human being? Why did he split the mountain with one punch??" A certain Martial King was dumbfounded. And Bai Mu said, it's none of my business, I just punched them lightly, why did they all fall down?
