Half a month later, Zhouyang seized the opportunity when several Nascent Soul Stage cultivators of the Great Brightness Immortal Palace were sent out on missions, quietly escaping from the Spirit Mountain where he was staying, then flew eastward without looking back toward the Boundless Desert Sea.
He found the timing to be extremely clever, and with his superior means of concealment and stealth, the cultivators on the mountain never thought that a dignified Nascent Soul Stage cultivator would do such a thing.
It wasn't until two days after his departure that Yin Hanguang received the news and discovered the letter Zhouyang left in the cave mansion.
The letter from Zhouyang did not reproach Yin Hanguang for anything, merely stating that he had nearly completed the task Yin Hanguang requested, and did not wish to linger any longer in the Westernmost Cultivation Realm, hence his departure without farewell.
