Chương 587: Chapter 437: The Immortal Shadow Reappears

This was an encrypted intelligence letter sent by Luo Wenzhi, the master of the Red Dust Tower. Only Gu Chen could open it through specific means, so even if intercepted en route, it would still be impossible to know the contents of the letter.

At this moment, the information Luo Wenzhi sent to Gu Chen told him that after various investigations by the Red Dust Tower, they had discovered traces of a mysterious woman from the higher realm, seemingly searching for something.

Therefore, Luo Wenzhi informed Gu Chen of the news right away.

There were many ways for the Red Dust Tower to deliver messages, but the fastest was through a type of spirit bird they raised internally, which was incredibly fast and most suitable for delivering urgent messages.

"Mysterious woman?"

Seeing the intelligence letter, Gu Chen immediately thought of the stunningly beautiful woman he had seen in Youzhou.
