This is a strange kind of isekai. Death isekai, game isekai, I can barely accept those, but why can I even isekai by breaking a fish tank? Moreover, I was even isekai'd into the world of Overlord as a world-destroying magic tree? No! Reincarnating as a plant is already tragic enough, and Ainz Ooal Gown, the undead king, has accepted a quest from the Adventurer's Guild to kill me! I want to change my fate! To survive! I want to surrender! Ainz: Since I've accepted the commission from the Adventurer's Guild, a deliberate failure would damage the reputation of Ainz Ooal Gown (the "surrender" key has been removed). I died as soon as I was isekai'd, but there's still a chance, return~ From the moment the magic tree first came to this world. This time, I must change my fate! Survive!
