"Why would the collapse of the World Tree bring about the destruction of the world?"

"Suppose these represent the vulnerabilities currently available for invasion in this world."
It waved again, and with a thought, most of the glowing points vanished completely.
"Once the world stabilizes, such vulnerabilities will decrease drastically. Similar phenomena may still occur, but they will become 'occasional' rather
