I, the Demon God of Destruction, Was Summoned by the Heroines

Help! What should I do if I am summoned by a beautiful girl from another world as a hero? Waiting online, it's very urgent! I, Ye Yuan, am a professional destroyer and part-time sleeper. Unexpectedly, I was accidentally summoned by a "newbie village". The bound system is called "Salvation Contract", the mission is to "save the world", and the teammates are the standard three-piece set of "Saint, Knight, and Magician". There seems to be nothing wrong with the script. The problem is - I am the final BOSS! As a result, the style of this world began to look wrong. Purify monsters? Sorry, I chose to pack and eat the monsters and the land together. It was crunchy. Overthrow the tyrant? It's too troublesome. Wouldn't it be more interesting to lock the tyrant and the loyal ministers in the same room and let them play "werewolf" by themselves? Fight against the evil god? Damn it, isn't that thing my spare food? The three heroines looked at me more and more strangely... "Lord Ye Yuan, please, can you seriously save the world?" "No, not unless you tell me a bedtime story first." Can the world get any better? I'm looking forward to it.
