Standing before a wall, Shin looked at his work, feeling a bit proud of himself.
He had spent three whole days just to fix all the damaged parts of the grand formation covering the entire underground temple.
This was the fourth day since he disappeared, but he could not do anything about it since Uno told him that the ones hunting him were right outside the temple, which was close to finding this place.
Fortunately, the grand formation was not that damaged. Most of it was just exhausted from existing for a very long time.
He was able to fix most of the damaged parts of the formation, even with his limited knowledge of Rune Formations. His solid foundation in rune mentalism and basic to intermediate formation knowledge was built up properly.
He also had a bit of knowledge about ancient cultivation due to the books that Professor Henry had given him.
