Although the Supreme Elder Wang Weizhen was exceptionally talented and possessed incredible strength, he had initially cultivated using the same method as the Qingxu Sect's signature Qingxu True Scripture.
When Bai Ziyue entered the Inheritance Hall, he learned through some records that when Wang Weizhen formed his Core, he had condensed the Fifth-Grade of the Middle Third-Grade Golden Core.
This quality of Golden Core was only at the level of a Solid Pill; generally speaking, wanting an extreme refinement to take that next step was almost impossible.
At least, the Primordial Spirit Celestial Tribulation was absolutely impossible to overcome.
The Primordial Spirit Tribulation, in terms of power, was thousands of times more intense than the Tier-Breaking Pill Tribulation.
Unless there were some immense fortune, immense luck.
Moreover, breaking through to the Primordial Spirit Realm was itself something worth celebrating with a massive banquet to announce to the world.
