Although Klein was urging them on the surface, he actually threw Life's Cane to the bottom of the magnificent staircase and threw it at Lovia, allowing her to treat herself and Colin Iliad's injuries.
As a former Rose Bishop, Lovia was the least afraid of the negative effects of Life's Cane. Regardless of the changes in her body, as long as it didn't involve the spirit, she could treat them.
At the same time, Derrick quickly ran towards the collapsed battlefield in the middle of the stairs, picking up the severed arm of the Chief.
As long as a broken limb wasn't lost, Life's Cane could heal the injuries, restoring it anew!
With an exaggerated smile, Klein nodded at Colin Iliad and leaped into the fog of history. He dashed to a time before the First Epoch and hid in a fragment of light.
