The Greatest Reinforcement

The condition of the Systems wasn't as absolute as compared to a century ago.

First of all, there now existed enemies like Slayer and Stencil with powers similar to Zaira. Secondly, the Main Character—Arnark—had revived and was on a hunt to strengthen himself, causing the Systems to weaken in response as their Coordinates were stolen.

Slayer too was targeting the Systems to fuse them into his world and raise its foundation further.

In this precarious situation, the Grade 4 Systems of Reincarnation and Transmigration were engaged with Mystique and Technocraft. Meanwhile, the Regression System had yet to recover its strength, unable to use its Core Skill for a year from the after-effects of activating its Core Skill Manifestation.
