The newcomer was tall and thin, with a wooden, unremarkable face. It was Immortal Master Xie, whom Yu Ci had not seen for many days. There was no telling how long he had been there; in any case, Yu Ci's soul perception had failed to detect his presence entirely. Yu Ci also saw that Xie Liang was carrying the crow that had fallen over the mountain.
Yu Ci was greatly surprised. When Xie Liang flew over, he greeted him, "Greetings, Immortal Master Xie. Have you returned from the Sky Rift?"
Xie Liang gave a grunt, swept his gaze over Yu Ci's face, and twitched the corner of his lips in what counted as a smile. "While I was in the Sky Rift, Senior Brother Yu could hardly wait to send me one message a day, telling me that you had mastered the Qi Infusion Method and urging me to return and teach you. Is that what the sect's message-transmitting flying swords are for?"
Yu Ci lowered his head, unsure whether to laugh or feel moved.
For a great sect like the Li Chen Sect, there were two methods of long-distance communication. One was through specially raised message-transmitting flying hawks, prehistoric exotic beasts capable of long-distance flight at heights of ten thousand zhang, with speeds comparable to a Core Formation cultivator going all out. Once trained, they could identify directions and deliver messages. Though they seemed somewhat slow in the boundless cultivation world, their costs were fairly low. Li You's letter had mentioned them earlier.
The second method was message-transmitting flying swords. Compared to the flying hawks, they were far faster. With a flash of sword-light, they could cross a hundred li; to race from one end of the cultivation world to the other took only a few days and nights.
