Jiang Ying looked at the envelope. The recipient's name was not written on it. There was a wax seal on the back of the envelope, and it was obvious that the emperor had not touched the letter.
"This letter appeared in the imperial study last night. I asked the servants, but they didn't see anyone suspicious enter. I was worried that there was something strange about this letter, so I didn't open it," the emperor said.
Jiang Ying thought for a moment and suddenly remembered that Ning Yue had given him a pair of rubber gloves and a mask a few days ago. He carried these rubber gloves with him. After thinking for a while, he put on the mask and gloves.
"Imperial Brother, why don't you let me take a look?" he said.
"What equipment is this? It looks so convenient. Do you have more?" the emperor asked.
"Yueyue gave this to me. Her master probably gave it to her." Jiang Ying didn't want to say anything else.
