The Number One Lackey of the God of Blocks Wants to Die

I, Li Nian, a great magician in my thirties who had accomplished nothing and had no worries, finally committed suicide by jumping off a cliff. However, I was unlucky enough to meet a man who claimed to be the God of Cubes, and made me travel to a different world. In this world, he turned out to be an evil god, and I turned out to be his number one lackey? "Please, you are very weak, can you practice again?" I didn't want to say this to the lovely brave man in front of me. It's just that people can't help themselves in this other world. If I didn't say this, the smelly cube would extend my life. Alas, I just want to die.
