Chen Nan and his group are indeed among the strongest of the young Human Clan.
Of course, Su Qingqing and Liu Tiantian aren't weaker than Zhao Han and his group, but they have other matters to attend to, and besides, Chen Nan didn't want to bring them along.
After all, they've been away from the Mortal World for over a decade, and it's not reasonable to leave soon after reuniting with friends and family.
Chen Nan, Ye Yiyi, Ziyun, Zhao Han, Hua Xian'er, along with two Divine Beasts and a Double-headed Sky Demon, form an incredibly powerful team.
As Chen Nan's son, Chen Yi also wants to join him in eradicating the Heavenly People Clan remnants.
However, Chen Nan stopped him, insisting he stay on Earth to accompany Gongsun Yudie, as it wouldn't be fair for them both to leave her.
The group set off, traversing the Void, and soon arrived at the Panlong Star Domain.
This is the largest Star Domain in the Human World, with countless planets clustered within it.
