Conquer the world, young man!

Congratulations, host, for activating the system and being given a great mission. Proceed into the unknown world! Su Liang is just an ordinary citizen, with no bad habits other than being a bit of a homebody.
And having never done anything particularly remarkable in his life, even the usually gentle boy couldn't help but swear in this situation: "What the hell is going on?!" Young man chosen by the great Tom Sue, strive to conquer the world!
Su Liang: System, I have a question. It says I should conquer the world, but the mission it issued has nothing to do with conquering the world! System: Host's rights are insufficient to access.
Su Liang: This can't be! What about human rights?! I'd rather conquer the world than get involved with these people! System: This is all the will of the great Tom Sue. As long as you conquer these people, you can naturally conquer the world.
Su Liang: What kind of twisted theory is this?! All this talk of a Mary Sue god is just for show, isn't it?! Su Liang has become a character in an anime he watched called "K," a cannon fodder character named Totsuka Tatara who dies right at the beginning. And this world... why is it so strange? A mix of various anime, completely illogical!
