Both events occurred simultaneously; the attack of the Androids as well as Shenlong. It was why Desir had difficulty calling in for help. So far, the Mutants could still fight the Androids but the number of casualties was still rising. If the martial artists joined the fight, things might turn up a notch.
The battle between the Androids and the Mutants were coming to a climax. Roughly 300 Androids were destroyed or disabled and over 1,500 Mutants were killed or severely maimed.
While the Mutants had more casualties, they had only lost Level 2 weakly Mutants and very few Level 3 Mutants. Hence, even though they had lost many fighters, they had barely shed any amount of combat prowess. Not only did they remain strong, but their attacks also became more coordinated and focused while the Androids were not doing so good themselves.
