My Name Is Saiki, but I'm Not 50/50.

My name is Qi Mu, and I am in harmony with everything in the world. Is the Son of Destiny who comes to take revenge the real Jin Dan? I'm 50-50 with Destiny's Child. The demon dragon in the virtual fairyland wants to bite me to death? I'm evenly matched with the dragon's teeth. If I bite you to death, I'll break your teeth first. The sealed Eternal Demon Lord breaks out? I'm still 50-50 with you. The arrogant immortal king wants to ruin my disciple's marriage? Sorry, I passed this test first.
