Xinghe and Mubai could not help but think, Thankfully these people were not corrupted by He Lan Yuan, or else even without He Lan Yuan, they would be able to dominate the world.
Therefore, even if Xinghe could help them solve their base's defense system, she would have to wait for the military to arrive first, or at least until she received one hundred percent confirmation that they were willing to return to Earth. Regardless, everyone there had to be taken away, leaving them there would only create a hidden threat for Earth.
No one could guarantee that these people would not suddenly lose their minds and follow in He Lan Yuan's footsteps.
