(Replying to a book review: As for the matter of the three units in 0079, Yi Zui does not know the specifics, but this is a changed novel. Whether it is one unit or three, this book merely follows the original work; it is not the original work. If you want to see the true original, you can watch the anime. Why come read Yi Zui's Mecha Wars Infinite? Yi Zui admires your questioning and self-righteousness. Zero fan value, heh.)
Xiao Ran remained at D.S.S.D for one reason: he had to wait for D.S.S.D to compile the technologies he needed and hand them over to Luo, who would then bring them back to Orb for combat-oriented improvements—more efficient Nano Repair Systems, more flexible and more powerful Light Energy Shield Systems, and the Radiant Transmitter System, which could now be used freely and activated faster and more conveniently.
All of these D.S.S.D technologies had existed from the start for the exploration of deep space. They could naturally be used in combat, and their self-repair and self-defense capabilities were sufficient as well, but they could not perfectly bring out the true effects of those technologies in battle.
Take the Radiant Transmitter System, for example. When applied to the Stargazer Gundam, it used a solar sail that endured solar wind as its foundation, gradually and slowly gaining nearly limitless navigation capability. Its speed would increase with time, making it an extremely useful navigation system within the Solar System in this world.
But when applied to the Destiny Gundam and Strike Freedom Gundam, once the Radiant Transmitter was activated, it converted the special power it obtained into powerful light pressure, forming wings of light that served as auxiliary propulsion during acceleration and granted explosive speed. Though both operating modes derived from the same technology,
