Condition
The reason Taran thought that it was a good bargain was that the guild could use this ability. Krune can awaken a Spirit ten times faster than anyone. Depending on the situation, they can have him awaken some big shot's equipment who really wanted to have a Spirit awakened. In exchange, they could obtain some benefits here and there. Besides, they could continue to study his method and might be able to copy it in the future.
'Of course, Krune's actual cultivation level is too low, so he can only awaken low-level Equipment Spirits right now. We will need to invest more resources in him to get his cultivation going faster. His cultivation speed is already quite great too. Perhaps it was because it had been blocked by the Calamity Laws for so long that it got lost now. Maybe in a hundred or two hundred years from now, he'll already be in the God Core Realm.'
