Ge'an and the others are afraid that Lin Chen might encounter an accident on the Huangyu Continent.
Moreover, given the current beast tide, Lin Chen is not from this world. If something goes wrong because of their matters, Ge'an and the others would feel guilty forever.
Furthermore, the Jade Cauldron Sect would definitely demand Lin Chen's return from the Giant Race, and the entire Giant Race would likely face the wrath of the Jade Cauldron Sect, with unimaginable consequences.
Although individual giants are powerful, they are no match for the Jade Cauldron Sect.
To say nothing of other considerations, the Giant Race cannot compare to the Jade Cauldron Sect's techniques for creating magic artifacts, as well as their powerful talisman inscriptions, warships, and killing formations.
They are not only worried about the Jade Cauldron Sect but also about internal affairs on the Huangyu Continent.
