According to their speculation, even if Wang Ye really returned to Earth, it wouldn't be long before he'd venture back into the cosmos.
Of course, the greatest possibility is that Wang Ye never returned at all, and they're merely bluffing.
After all, Wang Ye's secret is now China's secret, and the other side has ample reason to stall for Wang Ye.
But they don't dare to bet on this possibility.
If they bet wrongly and act upon Wang Ye's secret in his presence, they might face national annihilation instantly.
Therefore, considering the broader picture, they plan to delay for some time before truly heading to the Mariana Trench to uncover secrets.
