Despite Lin Chen passing on a Killing Formation to the Greyflame Giant Tribe that was not the strongest one he possessed, it was extremely suitable for the Giants.
Therefore, this Killing Formation cannot be casually taught to other tribes.
Lin Chen was not familiar with the Ancient Barbarian Tribe, who knows what constraints this so-called alliance had.
If the Ancient Barbarian Tribe were to become strong, they could just as easily rebel. An alliance was nothing, only true strength was the unassailable rationale.
However, the trade between Lin Chen and the Ancient Barbarian Tribe quickly spread throughout the Eastern Continent of Huangyu.
Simply using some stones and Spiritual Ore Mines in exchange for immensely strong weapons was a fantastic deal for the Giants.
Consider that just ten Heavenly Grade weapons suitable for the Giants could be exchanged for a Spiritual Ore Mine; such an advantageous transaction was indeed rare.
