The might of heaven is unpredictable, and the tribulation is difficult to surpass.
If a cultivator from the Cultivation World is to cross the tribulation, firstly, they must choose an auspicious day, secondly, adjust their mental state, and the third and most important point:
Elixir Medicines, Formations, Flying Swords, Magic Treasures, borrow as much as you can.
The heavenly tribulation puts enormous survival pressure on cultivators; ordinary Flying Sword Magic Treasures can be easily damaged and exhausted, while the powerful ones often consume a great deal of True Yuan, hence almost every cultivator needs to prepare a large number of lower-grade Flying Sword Magic Treasures as cannon fodder to exhaust the number of tribulation thunders.
Without doing so, even with nine lives one would end up completely drained.
