Yuan Dong asked softly, "What?"

Wang Chenghai lowered his voice and said, "I was wondering why the princess went to the backyard to search during the day, and asked Sister Yuandong to provide cover. I thought it would be better to put the two guards to sleep tomorrow so that they can be used day and night. But I didn't expect that there are patrols in the West Six Palaces at night, in groups of three or five. I encountered them several times along the way."

Meng Qi was surprised. She really didn't know that there were night patrols here. She didn't want to investigate at night at that time. She simply thought that the visibility was poor at night.

"Did you run into him?" Yuan Dong asked.

Wang Chenghai waved his hands and said, "No, they didn't see me. Luckily I had Ah Hua with me. Twice when people asked me who I was, I pinched Ah Hua."

Wang Chenghai's words eased the serious atmosphere considerably. Meng Qi even smiled softly, "Give Ah Hua some dried fish as a reward later."

"When I arrived at the back gate of Shangyi Palace, I thought I'd lay the stone flat as the princess had instructed. I then went to look for the stick with the wind whistle behind the tree, but I couldn't find it. I was just wondering if someone had taken it away when I heard a noise overhead. I was terrified and quickly squatted down. I heard the humming sound of a stick with the wind whistle hitting the tree."

Meng Qi was surprised. "So, that person saw you in the tree?"

Wang Chenghai nodded. "Not only that, that person also said that he heard yesterday that you had an upset stomach, and that I went to get a doctor but took the wrong way and took a long time to come back. He knew you were going to contact him."

Meng Qi understood. To be able to hide so deeply in the palace, it would be impossible without the ability to listen to everything. "What kind of person is he?"

"I didn't see it the whole time. The man was up in the tree the whole time. He didn't let me see, but just exchanged secret signals with me until everything matched. He even threw this down to me."

As Wang Chenghai spoke, he handed the brush to Meng Qi with both hands. Meng Qi took it. It was an extremely ordinary brush. She twisted it lightly, and the end of the brush popped open, revealing a piece of paper that did not have a single word on it.

That’s right, it’s the same as what Song Chengze told her.

Seeing Meng Qi remained silent, Wang Chenghai thought for a moment before continuing, "Since everything matched up, I told him to come to Lanxin Palace tomorrow night. He was stunned at first, but didn't ask any further questions. He just said he understood and said nothing more. I initially thought he had something else to say, until another group of people headed that way, and then I realized he was gone."

"You, didn't you see it? Wasn't he on the tree?" Yuan Dong said.

"Well, I didn't see it. And there was only one tree nearby. How he got down from the tree or where he went, I had no idea. He's really good at it."

Yuan Dong suddenly remembered what she had said to Meng Qi in the afternoon about why she didn't let Prince Rui take the person out himself. It was just as the princess said, every family has such a master, so it would be safer to let such a master take the person out.

"What time is the appointment?" Meng Qi asked.

"The hour of Hai."

"Okay, I'll go with you tomorrow night."

"No." They both said in unison. Wang Chenghai said hurriedly, "First, it's too late. The yard is in a mess. If the princess misses a step again, she might get hurt. Second, if there's an accident, I don't care, but the princess must not be put in danger. Third, what if the person only received the message that the servant was contacting him, and he didn't know that the princess was involved?"

Wang Chenghai saw Meng Qi's confusion and explained, "What I meant is that the princess wants to keep the truth about her visit to Hanyuan as secret as possible. This contact is also from the palace, so I'm afraid he'll think the same thing. If he sees the princess and thinks of something else or stirs up trouble, it will affect the prince's plans, which will be disastrous."

Meng Qi understood and thought it was indeed possible. She nodded and said, "How about this? I'll go over there early and hide in the west wing. Firstly, I want to see what that person looks like. Secondly, if there is an emergency, I can cover for you."
