The Lightning Saint turned to him and said, "Here you go. Kill him."
Although the World Tree was badly injured and had no more tricks left, the difference in power was too enormous. It completely rendered the World Tree useless.
He couldn't help but remember when the Lightning Saint clashed with the Frost Saint. He realized both of them hadn't utilized all their strength. In fact, the Lightning Saint might use a portion of his power to protect him and Ava back then.
With this, the battle had ended. Theo had no time to hesitate since the longer he took to kill the World Tree, the more chance he didn't end up killing it.
So, Theo flew toward the World Tree while raising his sword, cutting the World Tree with his illusion.
The World Tree was split into two, especially around the destroyed part and the area where it gathered the Magic Power.
