Zhang Sicheng, member of the Thainan Observation Group.
Early in the morning, before dawn, the middle-aged man nestled in the small burrow used by the observation group members was awoken by the arguing noise from outside.
He was fluent in the common language of the Western Human World and even understood Sydney language. As for the Northern Kingdom's Nuo language, he could comprehend it if spoken slowly... but he truly couldn't handle the way those two outside were spouting it.
So, he got up, put on his coat, and under the watchful eyes of his group members, signaled that he was going out to see what was happening.
The member who woke up was an elderly man, Liang Zefu, who was a light sleeper. Seeing Zhang Sicheng's gesture, he nodded.
