Chapter 111: Overlord

This thing already entered Keon's mind before. Why is it that even after a thousand years no one has ever created the same barrier that humanity has?

There were more and stronger Mystics amongst humanity now. Why can't they recreate it and chose to stay in only 4 measly Realms?

It comes to the point that the government even had to let some people die first after a weak point in the barrier appeared to prevent overpopulation

"To create the barrier, the strongest Hero needs the power from the other 4 Heroes. He was the catalyst and the only person that can create such a perfect barrier that even Lord Ranks cannot destroy"

"If not for the barrier's old age, weak points wouldn't regularly appear on it. From this, it can be seen how special the missing Hero is"

"Using all the 5 Heroes power, they managed to enclose 4 Human Realms inside a barrier. However, that left the 5th Hero in a vulnerable state"
