After the Spiritual Energy Vortex comes the Thunder Tribulation.
Watching the Thunder Dragons fall from the tribulation clouds, Yang Zhenshan's expression remained calm and unruffled.
The Golden Core Thunder Tribulation is a gift from the Heavenly Dao, as well as the operating rule of the Heavenly Dao. The reason why the Heavenly Dao has such an operating rule is actually quite simple: Spiritual Energy gathers, transforms into clouds, clouds roll and thunder moves, thus creating the Thunder Tribulation.
Simply put, it is a natural reaction triggered by the gathering of Spiritual Energy during the Core Formation process.
Is it possible to successfully form the core without the Thunder Tribulation?
The answer is yes.
If there is no Thunder Tribulation, the core can still be successfully formed; it's just that it would be a Fake Pill.
Just like Yun Xiao, he did not undergo the tribulation, so he did not comprehend the Taoist Divine Power when forming his core.
