Yi Yun was ultimately not from the Chaos Heavens. The future fate of the humans and Fey in the Chaos Heavens was not something he needed to concern himself with.
Under the Heavenly Dao's evolution, the various races had to fight for their own survival.
Therefore, swearing on his Dao heart to not be at odds with the Fey's interests was nothing.
From Yi Yun's point of view, the greatest danger was the Ancestor God.
He had no idea when the Ancestor God would recover and he had little time to strengthen himself. He needed the opportunity to transcend the Fey Altar's Heavenly Tribulation.
It was naturally against the rules for humans to enter the Fey Altar.
However… the allure of becoming Fey Patriarch was too great.
The Ruins Emperor was no longer young. If he could not attain his goal in the years to come, there would be no more hope left for him.
