Although the Little Fire Dragon showed great strength, Fang Zheng didn't let it follow him and fight all the way.
The reason is simple, the Little Fire Dragon's attack power was too strong, and Fang Zheng couldn't find any usable parts at all! It was a waste of effort!
So Fang Zheng used the Little Fire Dragon as his secret weapon, carrying it on his back while he and Iona were responsible for crossfire — by the way, Iona as a Fleet Girl, was also quite skilled in shooting. However, Fang Zheng noticed that she didn't like using rifles or sniper rifles, but often carried a grenade launcher around instead...
Maybe that's some kind of occupational habit?
Anyway, with the cooperation of the two of them and a dragon, all those invading Forerunner Guardians were basically wiped out, and Fang Zheng discovered that these Forerunner Guardians could be categorized as follows.
One type looks human, carrying guns and firing BIUBIU wildly.
