The BETA gathering on different planets was indeed greatly beneficial to Xiao Ran and the others. They could destroy the largest number of BETA while eliminating the nests. However, it also created some trouble for them: the BETA that had originally been scattered across each planet had now all gathered together, naturally increasing the difficulty of their campaign.
But regardless of whether the difficulty had increased, the Burning Legion had to eliminate all of those nests. Nor did they need to be as hurried as the Jeffrey Squad had been when attacking Mars, when they had directly used two Dimension Devourers to erase the entire planet. This time, they would have enough time to clear out every nest one by one.
Of course, Xiao Ran did not expect this Legion Mission to ultimately reach a hundred percent completion. For a mission like this, combined with the enormous BETA population, he could fully accept it as long as they reached somewhere between sixty and eighty percent.
To reach that point, the fastest method was naturally to purge the major planets in the Solar System. If they could truly destroy all the nests on the nine... well, the current eight planets, then they would probably meet the minimum mission completion requirement of over sixty percent.
After all, it was unrealistic to rely solely on the Burning Legion's current personnel to completely eliminate or drive out the BETA scattered throughout the Solar System. There would always be places they could not cover, and there would certainly be fish that slipped through the net. In short, as long as they could complete the mission and successfully let Ingram obtain a territory card, everything afterward would become much simpler.
Whether they brought over fleets from the various worlds or directly relocated the insects from Fleet
