If ghosts want to become stronger, apart from a long period of accumulation, the fastest way is to devour each other, and one will wax and wane.
What people don't know is that the evolution of the world is also like this. It will take a long time to perfect the rules of the world. If you want to become strong quickly, swallowing the weak world consciousness becomes the best choice.
In order to defend his own world and avoid the destruction of the world, as part of the world consciousness, Qiyuan has no choice but to go to various small worlds that have not yet completed evolution, enrich the laws of the world's operation, select powerful combat forces, and enhance the power of the world.
Following the people's prayers, Qiyuan came to the first world - "Tutor"
[Ding dong! Congratulations on unlocking the first main character Sawada Tsunayoshi!
[Ding dong! Congratulations, Sir, the law exploration degree has reached 1%]
[Ding dong!
…
"Wait, exploration requires me to become stronger together with them?"
"Of course! Master Messenger, only by skillfully using the current power system can you understand the laws of luck in the current world!"
Well, everything is to protect my own world... Of course I volunteered... T^T
(Big change, special change! It will be unlocked after the change. If it goes well, it may be comprehensive. If it doesn't go well, it will only be written as tutor for the time being, or it may be written as worry. Sorry for the writing, and sorry for the OOC.)
Purpose: Getting rich first leads to getting rich later
