In reality, the Heavenly Gates were also how the four races in the Heaven strengthened their rule over the Land. Elites from various races would be gathered and given the best cultivation conditions. The most outstanding among them might be able to form their Gold Core and become assistants that the four races could use when they ascended to Heaven. Even those who were left behind were elites in the Land, no matter whether it was in terms of their strength or the power supporting them. Once they entered the Heavenly Gates, they were the pupils of the Heavenly Gates and owed the Heavenly Gates a figure. Thus, they were naturally respected and supported the four races in Heaven.
Of course, this was simply the original intention of the four races when they first built the Heavenly Gates. In reality, after countless years and changes, although the essence of the Heavenly Gates was still the same as what the four races had wished for, there were some changes.
