The method Xu Yi adopted was nothing unusual.
He simply pursued two approaches at once. The first was to have all the native tribes already recruited by the Xinfei Merchant Guild actively contact every other native tribe they could reach.
Although the level of civilization on the Demoncloud Continent and the Goblins' rampages severely limited each tribe's reach, contacting them one by one would create a web that extended to more and more native tribes.
As for whether those native tribes would be willing to come once contacted?
Xu Yi had no need to worry about that.
The native tribes on the Demoncloud Continent had long suffered at the hands of the Goblins. Combined with their own low productivity, they could barely survive, let alone keep themselves fed and clothed. How could they turn down such an excellent opportunity to gain safety and have all the food and clothing they needed?
Even if they had doubts, with such a good opportunity before them, they would at least send someone to see for themselves.
And once they had confirmed the truth, there was no way they would refuse to come.
The first approach was relatively passive, while the second was far more proactive.
Xu Yi sent out almost all the Mana Airships, having them continually search the surrounding lands from high above.
Whenever they discovered traces of another native tribe of intelligent beings, they would immediately investigate and mark its location. Once they reported back, Xu Yi would send a unit of the Xinfei Merchant Guild Guard Corps to eliminate threats along the route and find that tribe.
After that, whether through incentives or intimidation, they would find a way to get the entire tribe to relocate.
In just these past three months or so, the Xinfei Merchant Guild Guard Corps
