Ps: hello I am the author this is a warning.

My first language is not English, so the grammar of this novel is not that good but if you see any wrong sentence in the novel I tried to improve it to the next chapter.

So without future ado pls enjoy my novel.

Edit: I will be also posting some of the chapter to Royalroad.Com
