Bone King: Homemade plug-in, I am the god of destiny

[Overlord + Not Joining Nazarick + Human Players + Self-Made Plug-ins]
After traveling to the world of Overlord, he found that the Yggdrasil game was about to shut down. What should he do if his application to join Ainz Ooal Gown failed?
Han Yu said he was not panicking.
He spent three years repeatedly synthesizing several world items, thermal stones in the Yggdrasil game, and asked the game operator to make a plug-in item.
[God of Destiny]: Give the characteristics of the target game player of the contract, and when the other party meets the conditions, help him obtain a recorded extraordinary profession or change his race.
…
When Han Yu successfully descends into the other world, how much impact will it have on the fate of this world?
Will human countries still move towards their destined ending? How will the True Dragon King, the strongest combat power in the other world, respond? Will the Great Underground Tomb of Nazarick still be invincible?
