Wu Zhou, the situation dramatically changed overnight.
The Iron Sword League was raided, their main base was empty, Nine Swords were dominated by Lu Bei, even the standing for thousands of years Heavenly Sword Peak was gone.
With no roots to provide stability, it's hard to gain the trust of the people.
Qingqian suffered a crushing defeat, retreating from the front lines. They lost control of two provinces overnight and were miserably struggling against the Imperial Sect in Guan Province.
They had only two choices: Either they held out until death, or let Qiyan enter their territory. There was no third option available.
The most pitiful part was that the Heavenly Sword Sect had changed its leadership. The second Sect Leader inherited the Abandoning Scripture. Qingqian no longer had a meaningful flag to raise, and their true colors were inevitably exposed.
