Ye Feng did not need Li Chijiao to serve him hand and foot.
The reason for this statement was that, having just arrived, it was necessary to give the other party some benefits to show goodwill, making it easier to obtain the Heavenly Venerable Divine Ability.
As the saying goes:
More friends mean fewer enemies.
The hidden Immortal Emperor of the Li Clan had an unknown level of strength and mastered the Heavenly Venerable Divine Ability—his power was immense. Being able to turn him into an ally was naturally the best choice.
At the very least, he must not become an enemy.
"No need to serve me hand and foot. Your dark ailment originates from your soul and has spread throughout your meridians, lingering without cure. It has already led to the stiffening of your meridians. If this continues, not only will your cultivation level regress, but your foundational essence will also be damaged."
Ye Feng saw through everything with crystal clarity.
