【You become the Lord of Extermination】
[You feel that using star cores and violence to destroy civilization is too slow, so you decide to destroy the Tree of Existence. 】
[Nanook thinks you are a fool, Aha laughs at your lack of wisdom. 】
[You cut off one of the roots of the tree of existence. 】
[Nanook thought he was crazy, Aha couldn’t laugh anymore, the hunter stopped chasing the medicine man, and the last king appeared directly. 】
……
[You have become the No. 85 member of the Genius Club. 】
[You hacked some of the dolls in the Black Tower to serve you as your maids. 】
……
【You have become the Envoy of Fertility. 】
[You will increase the life span of the fox people from 300 years to infinity]
[The fox man is very grateful to you, but Demon Gong Fuzu shot the arrow at Luofu. 】
……
【You have become the messenger of joy】
[You don’t seem to have changed much. You think this is Aha playing tricks on you. 】
[You have been planning for a long time and you tricked Aha once. 】
……
One day, you, who have been living in Luofu, received a prop from the Black Tower.
It contains a photo of you with numerous maids from the Black Tower, as well as a maid puppet from the Black Tower.
