By the time Ji Xinghe finished repairing all the damaged Mountain-cutting Model Mechas of the Independent Group, the Peace Space Battleship, which had left the western war zone not long before, returned to the western war zone with all the new recruits of the Independent Group and a hundred Mountain-cutting Mechas.
Also, the Peace brought a large number of supplies needed by the western war zone from the Fifth Base.
Of course, when the Peace left the western war zone, it also took away a large number of supplies from the war zone.
For instance, the Mechas that the western war zone was unable to repair or retrofit were effectively recycled and reused at the Fifth Base, which had more complete repair facilities.
This was not a trade between the Fifth Base and the western war zone, but a unified distribution and management of resources. It had nothing to do with Ji Xinghe.
