Don't read this book and waste your time.That MC has no Common Sense at all.Gains any knowledge almost automatically like a world's best hacker and world's best martial artist.An assassin comes to kill him and then begs for mercy. WTF ?? ? Has beautiful girlfriend, but It's not because I am jealous that I rated this book 1 ⭐.(N jealousy at all)On serious note, if we could have 0 stars, I would rate this 0 stars.
