Heinz was in a room on the top floor of the tower and surrounding his body was an extremely sharp red aura.
This aura was not made by a spell, but due to the cultivator's effect on his surroundings as he trained his laws, more specifically his Law of Sword.
He was in a meditative position with his iconic black sword on his lap. His consciousness was nurturing the sword in order for it to obtain his spirit, allowing him to reach the Second Sword Realm.
He had been training almost all of the time since he reached this world. He had not made any true advancement yet, but there was no impatience in his heart.
Heinz knew very well how difficult it was to advance the comprehension in the laws, especially in his case since he had reached the 'Initial' level of comprehension.
If he were to advance to the 'Minor Completion' level, his laws would have a qualitative change, and it was required to advance to Rank 6.
