Invincibility Starts from Scanning the QR Code

Reborn in a world where force is respected, Su Mu was delighted when he found that everyone had a QR code above their heads! What? You said you have heaven-level martial arts? Sorry, I just need to scan the code and I will learn your heaven-level martial arts skills instantly. What? You said you have god-level bloodline? What, you may not know, as long as I scan the code, your god-level bloodline will be copied by me. What? Do you still want to sneak attack me? Sorry, I have scanned the QR code and followed you for a long time. I know every move you make.
