I Have Infinite Skill Points - Chapter 481: One Man Suppresses a War

In a world that blends the magic of the steam age with the grandeur of the medieval era, a man wakes up suddenly in a body he does not recognize, in a strange reality that does not belong to him, bearing a name that is not his and a mind stripped of all memories. His name is Jevan or so they say.In the city of Medlia, specifically in the lower district, where poverty and misery reign, the people are not ruled by laws but by fear of the gangs.Jevan discovers the existence of extraordinary powers known as Authorities abilities that defy all logic, wielded by some for domination and by others as a means of survival. Before long, he finds himself cornered on all sides:Bloodthirsty gangs, mysterious agents, secret organizations. He becomes entangled in countless troubles from a past that is not his own. In a city torn apart by class struggles, devouring those without power, Jevan begins a journey to uncover himself or the truth of the body he never chose and has no luxury of escaping.

This crossing is so strange, death crossing, game crossing, etc. are probably barely acceptable, but why can you cross even if the fish tank is broken?

and actually passed through the magic tree in “OVERLORD” that is said to be able to destroy the world?

No! It is sad enough to regenerate into a plant. The protagonist, Ainz Ur Gong, the undead king, has also accepted the adventurer’s guild mission and wants to kill me!

I want to change my destiny! Live! I want to-surrender!

Ainz: Since he has accepted the job commission from the Adventurer’s Guild, deliberate failure is detrimental to the prestige of Ainz Ul Christine (the “surrender” button has been deducted)

actually died as soon as he crossed, but there is still a chance to return~ from the beginning of the magic tree to this world.

I must change my destiny this time! Live!
