All of this had happened because of Chen Fan.
Even if he couldn't undo the curse of all the Chinese people, he could break a few Divine Chains. Qin Hao, Elder Mulei and Elder Wufen were only half a step away from the Golden Core Level. Once they were freed, they could go through the Thunder Tribulation right away.
And the other elders took the Heavenly Medicines Chen Fan had brought back from the Two World Peak.
During the three years in the Two World Peak, Chen Fan had traveled a hundred miles and found eight Heavenly Medicines. He combined one of them with flesh, blood and Golden Cores from the Ancient Demons, and made a cauldron of Mixed-essence Heavenly Pills.
Although those pills were considered inferior-grade medicine, they were effective to Connate Cultivators and could help them reach the Golden Core Level directly.
