The phenomenon echoed through all of existence.
Those who were on the warfront, those who were observing it silently, those who were plotting in the shadows, and even those who remained wholly uninvolved with the universe's affairs…
Without a single notice, completely beyond their expectations, the Demigods of the lower universe disappeared from the world.
Nobody knew why.
There were no obvious signs of a restriction being activated to summon the Ancient Battlefield.
Even if one assumed there was a problem in the Abyss, the problem still didn't make sense.
It had been so long since the war began. The last time the Ancient Battlefield opened was dozens of thousands of years ago, so naturally, nobody expected someone to open it now.
