After this discovery, Peter Brown was somewhat hesitant about whether or not to develop this place as his own base. He was worried that if there was another expert above the Mahayana stage coming out of the passage in the North Pole, even if it was not the Mahayana stage, as long as a Nascent Soul Stage strong person appeared, there would be no guarantee of safety for Mars.
However, this thought only lingered for a moment. Peter knew in his heart that if there were Nascent Soul experts appearing here, Earth would be equally unsafe. He couldn't give up the construction of Mars because of this.
Peter didn't plan to deal with Earth, after all, the political environment there didn't allow for change, but Mars was different. This was a desolate land, and he could do whatever he wanted.
At most, all he needed to do was to find some powerful formations to protect Mars from the Cultivation World, which shouldn't be too much of a problem.
