Reborn as a legitimate daughter, huh? Why is she different from her previous life?

Zhang Hua immediately went down the city wall to open the gate for Feng Chengyin. The guards who were on duty with him were all his own imperial guards, and no one was willing to say anything.

Feng Chengyin couldn't tell what he was feeling right now. He felt a little regretful, but also a little helpless.

If it weren't for the fact that various forces had been keeping a close eye on the situation in the palace recently because of the issue of which prince would succeed to the throne, he would not have taken advantage of this opportunity to enter the palace.

Wouldn't it be better to just 'fly' in by yourself?

God knows where those secret guards are stationed near the palace...

After Feng Chengyin took over the "Fu Ling Shui Xuan" order from Zhang Hua, he brought Ying Zhou into the palace.

The two of them went straight to the palace where Concubine Li lived. It was already the second watch of the night and Concubine Li had already gone to rest.

Ying Wu at the corner gate had been waiting here for a long time. When he saw the two of them, he immediately stood up and said, "Master, deputy commander!"

Feng Chengyin waved his hand to indicate that he didn't need to be polite. This was the imperial palace, and if he wasn't careful, people might find out that he was a replaced 'eldest prince'.

"Master, during dinner, I paid special attention to Cui'er, the maidservant beside Concubine Li, and saw with my own eyes that she brought a food box into Concubine Li's bedroom."

Feng Chengyin whispered, "You mean there is someone hiding in Concubine Li's bedroom?!"

"I'm not sure." Ying Wu didn't see anyone hiding in Concubine Li's bedroom, so he didn't dare to make up stories. He continued, "But why would she bring food into the bedroom when she was fine?"

Feng Chengyin: "Are you sure no strangers left Concubine Li's palace?"

"Yes, I am sure that no strangers left!" Ying Wu replied affirmatively.

"Okay, then let's see what secrets are in her palace..."

"..."

Feng Chengyin jumped onto the roof himself and asked Ying Zhou to guard the window of Concubine Li's bedroom and Ying Wu to guard the door of the palace.

If there really is something fishy going on in Concubine Li's palace, even if this arrangement fails to catch the person, at least we can stop him for a moment and at least see his appearance.

At the second watch, Concubine Li was already sleeping soundly. With the help of the moonlight, Feng Chengyin slowly saw that there was nothing unusual in her bedroom except for an old nanny who was dozing off and two palace maids who were also sleeping with their eyes closed.

Feng Chengyin frowned. He had also seen Cui'er, the trusted maidservant of Concubine Li. But Cui'er was not in Concubine Li's bedroom...

Feng Chengyin still didn't know which wall was the one that Bai Riyingwu mentioned in Concubine Li's bedroom, so he had to fly down first.

"Hide!" As soon as he landed, Feng Chengyin felt that there were patrolling imperial guards coming this way, and he immediately asked Ying Zhou and Ying Wu to hide first.

When Shen Nanzhi and his men were patrolling near Concubine Li's palace, they seemed to hear some noise, but when they got closer and listened again, there seemed to be nothing special.

The people behind him saw him standing still and couldn't help asking, "Captain Shen, do you feel anything unusual?"

Shen Nanzhi lowered his eyes slightly and said coldly: "Nothing, continue patrolling!"

He knew who was responsible for the unusual movement just now. If his good cousin hadn't given the secret signal, he would have wondered whether he should knock on the door.

Although the late emperor is no longer with us, the final arrangements for the ladies in the palace still have to be decided by the new emperor. As long as they live in the palace for one day, it is the responsibility of the guards to protect their safety.

Shen Nanzhi and the Royal Guards quickly left here to continue patrolling elsewhere. Feng Chengyin and the other two who were separated by a wall also breathed a sigh of relief.

If this really happened, even if he was the fourth prince, and broke into the bedroom of the late emperor's concubine at night, he would not be able to explain himself even if he had ten mouths!

"Do you have any drug-induced smoke with you?" Feng Chengyin asked Ying Wu. He was the one with the most messy things among the Shadow Guards, and even Feng Chengyin, the master, knew about this habit.

Ying Wu smiled awkwardly, then touched his waist and said, "I really have..."

Ying Wu lit the smoke and poked a hole in the window of Concubine Li's bedroom, then threw the smoke in. After a while, the three of them covered their mouths and noses and entered Concubine Li's bedroom.

Ying Wu walked quickly to the wall that he had felt was strange during the day and whispered, "Master, this is the wall."

Feng Chengyin made a "hush" sound to signal him not to speak. What if the wall was not soundproof and there really was a secret room behind it? Wouldn't the people inside be able to hear them talking?

The three of them searched the area around the wall but couldn't find any mechanism. Feng Chengyin couldn't help but become anxious. Ying Wu had said before that the smoke would only be effective for half an hour.

Most of the time has passed. If we can't find the mechanism...

Just as he was anxiously wondering whether to continue looking or come back another day, he accidentally touched an antique shelf beside him. He subconsciously raised his hand to steady the shelf. Fortunately, nothing on it fell down.

Suddenly, he found that there was something strange about a small incense burner on the shelf. When the antique shelf was shaken just now, all the ornaments on it shook slightly, but the incense burner did not move at all.

Feng Chengyin reached out to pick up the incense burner to have a look. Was it too heavy?

How heavy can a small carved hollow incense burner be?

Sure enough, this small incense burner can’t be lifted at all!

Feng Chengyin tried to turn the small incense burner. It could be turned counterclockwise. After the small incense burner turned three circles, a slight "boom" sound came from the wall, and it split into two, revealing an iron secret door.

The three of them came to the secret door and found that there was a keyhole on the door, which required a key to open...

The corners of the three people's mouths twitched violently. At this moment, their nerves were highly unified. They were all thinking, could it be that Concubine Li had imprisoned someone in her own bedroom?

Feng Chengyin was beginning to doubt himself. Could it be that all his assumptions were wrong?

Now that they had seen the door, there was no reason to give up. Feng Chengyin quickly calmed himself down and asked Yingzhou and the other man to look for a key in the house.

Five minutes later, the three of them searched all the places in the house where the key might be hidden, but they still couldn't find the key that matched the secret door, and their faces looked a little bad.

Who can understand the feeling of having to pull back your foot after taking the final step?

Suddenly, Feng Chengyin thought of someone, "Ying Wu, where is Cui Er? Which room does she live in?"

Yingwu also remembered that he didn't see the food box that Cui'er brought in during dinner in the room. If the master hadn't mentioned it, he would have forgotten that he seemed to have never seen Cui'er leave after she came in!

Could it be that Cui Er is hiding in the secret room? !

Obviously Feng Chengyin had also thought of this situation. Does that mean that a key is not necessary to open the door of this secret room from the inside?

Or is there the same keyhole inside?

It seems that I am destined to return empty-handed today.

The three of them did not linger any longer. They opened the window slightly to ensure that the smoke in the house would dissipate quickly and then left quickly.
