Chi Xue was a clever man, even smarter than Po Di and Po Family's Youngest Brother. Naturally, he could think of whatever they could think of. In fact, when he first proposed allying with the Technology Cultivators, he had already anticipated what Ling Tian and the others might do. He had also come up with a way to deal with it, so he wasn't worried.
The reason he hadn't brought it up then was that they had already proposed too many "unbelievable" things. Simply allying with the Technology Cultivators was already hard for many people to accept. If they also proposed sharing their sect headquarters with them, even more people might refuse—and might even oppose allying with the Technology Cultivators at all.
That was exactly why Chi Xue planned to suggest it after they had formed an alliance with the Technology Cultivators. By then, the alliance would already be a done deal, and they would be more likely to accept sharing their sect headquarters with the Technology Cultivators.
Chi Xue had even considered waiting until Ling Tian and the others made a move to stop them before proposing it. Under that kind of pressure, they would be even more likely to agree.
What Chi Xue hadn't expected was that the Po Family Brothers had also anticipated Ling Tian and the others' ambushes and interference—and had already thought of a way to deal with them. That was a pleasant surprise. He wouldn't need to persuade anyone himself, and he could use this as a bargaining chip to convince the Technology Cultivators.
"Tsk, tsk. I didn't expect Po Di and Po Family's Youngest Brother to have some real ability. They actually figured out that Ling Tian would stop the Technology Cultivators from building bases, and even came up with a workable solution."
