A new app called "Time-Space Mailbox" appeared on Jiang Chao's phone. Through it, he could talk to people in the past.

"Zhu Di, once you've finished compiling the Yongle Encyclopedia, remember to bury it beneath the banyan tree behind Shaolin Temple. I want to read the original!"

What was going on?!
