I'm Not a Gatekeeper

I, Chen Xiao, am now an on-the-job gatekeeper. Why did I become a gatekeeper? I'm not afraid of you laughing, because I gained strength comparable to that of a god and saved the world. Look at how I use the knowledge gained from the Gate of Truth and the insights from my previous life to travel freely among the universe. There is a kind of bird that is not destined to be locked in a cage. Every feather of it shines with the brilliance of freedom. This novel and its characters are purely fictitious.
