Global Reincarnation: Only I Know the Plot - Chapter 888:

Samuel, a high schooler, got summoned with his classmates to another world as prophesied heroes. He expected glory, adventure, and a chance to save a kingdom. But those hopes were shattered when he discovered the truth, they were sacrifices, the gods who summoned them are no saviors, but monsters that feed on human souls. Among the victims is his little sister, dragged into the summoning by accident while she was delivering his lunch. Betrayed and marked for sacrifice, Samuel survives andmade a deal with (Arithmos) the God of war, with its power, he now vows to destroy every god and declares to take everything from them.

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!
