After hearing 'Ling's' words, Tang Kai and Wangsa finally understood.
As 'Ling' had mentioned.
It was indeed impossible for these resources to be supplied in vast quantities from any other direction in this territory. The only stable country in Wangsa's direction was Thailand, and with Wangsa himself as a well-connected middleman, a stable trade channel could be formed without having to cross through any unstable areas. There would be no worries about being robbed, having goods intercepted, or a sudden change in the political winds in Thailand.
Plus, Tang Kai and Wangsa already had a certain rapport, which formed the basis for trust.
Upon calculating all these factors.
Tang Kai turned out to be the ideal partnership candidate.
The combination of Tang Kai and Wangsa was the most suitable choice in this chain of interests.
The two of them quickly figured this out.
Tang Kai felt a touch of fortune.
