"The finest ingredients must be in the hands of the best chefs to become the most delicious delicacies.
The Sword Sect is the most powerful sect of sword cultivators among the Human Race, and your island's artifact refiners happen to specialize in swordsmithing. It's a match made in heaven, perfectly complementary.
Moreover, Family Head Cang must understand that the Sword Sect, as a sect of sword cultivators, undoubtedly has more respect for swordsmiths than any other sect. If you are willing to migrate to the Eastern Domain, you will surely receive the highest level of treatment." This is reasoning with logic.
"To show our sincerity, the Sword Sect is willing to allocate the Flying Peak near the Inverted Mountain Range to your Cang family, becoming your neighbors. Additionally, as a gesture of goodwill, I will also gift your Cang family a line of cloud-patterned immortal veins, which I believe your island's swordsmiths will certainly appreciate." This is enticing with benefits.
