You Want Me to Destroy the Sect at the Beginning? I Really Don't Want to Play!

Cheng Yu unexpectedly traveled to another world and joined the number one demon sect in the world! What? As long as you are disadvantageous to the sect, you can become stronger? Miejong is even more capable of being invincible in the world! Since it is a demon sect, it doesn't matter if it is destroyed, right? With this idea in mind, Cheng Yu discovered that he was wrong! Brothers and sisters are so kind! Although he has a lot of quirks, his outlook on life doesn't seem to be that upright! But it really suits my heart! There is also such a thing as hunting down a murderer thousands of miles away. Could this be done by the Demon Sect? I'm afraid it's not us who is on the right path! In this case, system, don't blame me for finding loopholes!
