As you read the story please keep these few thing in mind
1. English is not my main language.
2. What are you reading is fanfic, meaning I get to change few thing in plot
I might change few rule of power settings
maybe timeline but character will behave according to there original personality.
3. At the starting, main character has a mental age of six with alot of knowledge so he will behave childish and act like a brat. But as time pass he will behave like an adult.
4. MC will try conquer entire continent which includes both empire, either they will fight or surrender depending on that tang san might become enemy.
