New to Ultra? the Gangster's Favorite!

I, Ji Chuan, am a senior otaku from the Kingdom of Light (Ten Thousand Years Edition). The first time I went on a mission, I thought that fighting a two-tailed monster was a beginner's tutorial, but Dada gave me a hellish start. Fortunately, I have the thighs of Beria from my grandparents to hug, and the black technology of Hikali's plug-in, but before I had time to enjoy it, I was forced to wander. From being chased by monsters to fighting alongside Tiga, from operating a mecha in the Pacific Rim to the space-time battlefield of the Ten Warriors... Semi-invincible + no heroine + passionate + no intelligence
