Zhou Heng didn't give face to anyone, at his level, he no longer needed to give face to anyone.
He wasn't a Saint; he had his preferences and not just anyone could hitch a ride on this easy journey.
Zhao Duotian, as the head of the Zhao Family, had his inescapable responsibilities. Therefore, he followed the Zhao Family to the Dragon River Continent. The Zhao Family only had him, a Half-Step Immortal, and going to an entirely foreign land, they desperately needed his care.
Accompanying him, besides all the Zhao Family members, were Zhou Heng's parents.
According to Zhou Heng's original intention, he wanted his parents to stay with him until he obtained the Star Core and broke through to become an Immortal, after which he could take his parents directly into the Immortal Realm! However, Zhou Dinghai and his wife insisted on going with the Zhao Family, and no amount of persuasion from Zhou Heng could change their minds.
