"But before I go to Qi Country, I must still purge the Holy Sect." Ji Changsheng said. "A convoy leader once taught me a phrase — 'to conquer the external enemy, we must first settle the internal matters.' I refuse to leave the Holy Sect alone before conducting a thorough cleansing."
Although many people think the convoy leader was a bad example, who says only those in the light can be heroes?
As the eleventh marshal of the secret front, didn't the convoy leader make significant contributions? Serving undercover as the leader, but still maintaining his original intent and constantly providing supplies for our old base, isn't that admirable?
Ji Changsheng was quite impressed, hence he took those words from the convoy leader as axioms. The Holy Sect just had to undergo a major cleansing.
