Just like what Zhang Mengyao predicted earlier, the Legion Guild came to ask about the vassalage within the Tang Empire. Apparently, they came to the Taukai Family before they came to the Tang Empire's booth. So, the Legion Guild had a clear understanding of the vassal system. They had a clear goal for what they came for and straightforwardly asked for protection from the Tang Empire.
Of course, Tang Shaoyang and Zhang Mengyao did not immediately accept the Legion Guild despite their willingness to join the Tang Empire as a vassal. They listened to their reasons why they sought the Tang Empire's protection. There were three factions in total in South Korea, and two of them joined the World Government. To make it worse, the only faction from North Korea also joined the World Government.
