章節 135: Chapter 136: People of the Divine Sword Sect

Every time he heard about Ye Xin's situation, his master Wei Wushuang always managed to get reliable information from Ye Xin's master.

Originally Lin Qian did not quite understand how Wei Wushuang could receive news so promptly.

It wasn't until just now, when he saw the crystal Wei Wushuang took out, that Lin Qian recognized what exactly it was.

After acquiring the treasure trove of the Dangyuan Sect, Lin Qian had gained a broader knowledge of the items in this world. The information he understood was no longer limited to the Coastal State.

And what his master had previously taken out was called a Communication Crystal.

As the name suggests, this Soul Device, forged from various unique crystals, is used for transmitting messages.

However, Communication Crystals are always made in pairs or in greater numbers, as only those from the same batch can send and receive messages.
