The energy beams are much more destructive than the bullets.
They disintegrated the barriers around the undead and destroyed the undead later on. For some reason, Sam mostly focused on the flying undead. He didn't attack the Giants that much except for when he blocked and fought against the spears that are constantly coming at him.
The stage is filled with corpses. Wyverns, Hawks, Eagles, Vultures… All kinds of vicious flying beasts are there.
The corpses that fell on the stage and ground are being rapidly absorbed by the tree. The absorption speed only increased with every passing second. Sam didn't attack the tree though.
He let it be.
In fact, he made sure that he didn't accidentally attack the tree. He made sure that it is left undisturbed. Of course, the opponent didn't know that Sam even had such a thought in his head.
He just focused all his mental power on strategizing the next step.
