The trauma and a new path

After Ren woke up he was travelling through some mountains then a mysterious man in a black cloth came to Ren he said :- power is everything in this world but without a purpose even power can be meaningless tell me boy what do you seek then

 Ren came to reality until now Ren thought that he was getting powerful to protect his loved ones but now when he looked back he saw that he had no one to protect or...love  Ren internally got traumatized he was thinking no no no no no 

what  was I even doing up until now I suffered so much hardship for what ? This!!!

 then after some time Ren came to a decision he stood up and said to himself that he will bring peace with all races and if someone doesn't accept he will erase the world itself but soon did he know that now even the demon lords were assisting him already
