The spirit ship waited outside that massive thundercloud for a full half-month.
During this period, Yang Fei was tempted multiple times to go back and check, but was always persuaded against it.
Because starting from the fifth day, that thundercloud became incredibly active, with terrifying thunder and lightning releasing wildly as if never-ending.
Even though Yang Fei was now at the peak of the Mid-stage Foundation Establishment, he still felt fearful facing such terrifying thunder and lightning, having no confidence in retreating unscathed.
Everyone speculated that Wang Lei likely officially entered the Foundation Establishment stage from the fifth day.
And undertaking Foundation Establishment amidst such terrifying celestial phenomena, the level of danger was imaginable.
According to Zhuo Donglai, undertaking Foundation Establishment under such circumstances has not been seen even on Earth, let alone within the cultivation world of the Central Great World.
