"I must be absorbing the spirit power from that monster then… Better to focus on training then," he thought this was the case, and returned to focus solely on his training techniques, with the spirit power absorption technique running as well.
It was hard to run two training techniques at the same time, and yet he tried his best to run both together. When he failed, he had to run one for a few minutes, then alternate it with the other technique.
As time passed slowly, he was positive he was absorbing spirit power from that monster. Yet when the world got cleared, all he could see was nothing at all in front of him. His hand was touching thin air, and there was no trace of that bear.
"Don't tell me I vaporised it!!!" he blinked, looked at his body, and saw nothing wrong there. But when he looked at his two monstrous weapons, seeing them turn into two scraps and useless pieces of metal and ores, he knew he wasn't dreaming.
