The high probability is that he hanged himself and World Tree did not recognize him, so he died in vain.

How much courage it takes to live towards death and sacrifice oneself without any certainty.

Odin would not have done that without a heart that would lead to success or failure."

Well, Cai Gen quite agrees with this.

When the odds of winning are unclear, he bets all his wealth and life on it. He is indeed a ruthless and determined ruthless person.

If one eyeball couldn't be exchanged, he would probably sacrifice the second one.

Shi Huozhu saw that everyone was no longer angry. It felt so good to convince people with reason.

"Finally, the second before Odin was about to die.

His sacrifice was responded to and recognized by the World Tree.

The World Tree gives back to Odin the rune character that represents all the power rules of the Nordic world.
