Chapter 740: The Post Office with Lights Out

From the mouth of this person named Wan Xing, Yang Jian roughly understood what being a messenger entailed, which wasn't very different from what he had expected.

Firstly, Wan Xing, as well as the group of Li Yue and others who appeared in his hometown, and even a person named Zhang Tao whom he had investigated before, were all messengers; this much was certain. However, before they became messengers, they were all ordinary people.

The reason they were chosen to be messengers was because of an accidental letter.

A yellow paper envelope without a signature or seal.

Each person became a messenger after opening that letter and then arrived at this post office in an incomprehensible manner.

Once they entered the post office, their task was to deliver the mail.

The letters that appeared in the post office were irregular, but as soon as they did appear, the messengers would be brought into the post office and had to deliver the letters to a designated location within a set time.
