Mecha War: Starting from Gundam OO

Description

Yang Hui, who inexplicably traveled to the Gundam OO world, became a child and a member of the [Barren Bear] family.
With the monkey version of the system with countless flaws, Yang Hui is determined to change all the regrettable tragedies.
However, when he thought everything was over, he discovered that it had just begun.
(PS: Infinite Streaming, there will be spin-off characters and machines, but the story will be based on the main story. The early story will focus on Gundam, and the super system and fantasy system will be added in the later stage.)
Multiple female protagonists, some magic changes.
