That is unclear.
Moreover, Lu Yuru has been in closed-door cultivation for over half a month, and she just emerged to come over and get close. Does she know? Who told her? Has she told anyone else?
Unclear, too.
So, there's no way to investigate.
Asked Tian Jing—
"I don't know either."
Tian Jing explained to Yan Chuan: "His Majesty is worried that if the news spreads, evildoers might come to harm you. He sent me to understand the details of that treasure. Of course, whether to tell me is up to you; there's no pressure. Secondly, His Majesty cherishes talent and is concerned about dangers since you're so far away here, so he sent these two mythical weapons to assist you in self-defense."
As Tian Jing spoke, he turned his palm over, revealing two miniature mythical weapons: one with three heads and six arms, and another with hand-like eyes growing out of the eye sockets.
Mythical Weapon!
Mythological Armor!
