Hiro didn't care for the commotion caused by the sudden repair of the stronghold's damaged and dilapidated districts.
With the barrier in place, no one can pry into his secrets from the outside even if they wanted to.
The same was true for the Demon Tower, as Hiro was certain that the Great Demon families of this stronghold must have left backup plans.
Taking advantage of his presence in the core of the Demon Tower and the fact that the space had yet to be sealed by the power of laws, Hiro summoned the newly obtained summoning tokens.
He used his demonic energy to draw four summoning magic circles on the ground and placed the four tokens in the centers of each formation, respectively.
The first token had the words "Shadow King" inscribed on its surface.
The second token had the words "Monkey King" inscribed on its surface.
The third token had the words "Lord Aza'zel" inscribed on its surface.
