If it was a coincidence that Xining Sedum found them, then how could Bei Lizhong and Nangong Xiu, who had been following her, explain it.

Before everything was clear, Su Tingcheng didn't want to have anything to do with the two of them.

It looks like we're going to have to keep my distance from them in the future......

Thinking about the carriage and returning to Xining Mansion, she just got off the carriage when she met Ye Yutai, who was about to come out of Xining Mansion.

The two glanced at each other, and both looked away very tacitly.

Ye Yutai was busy working in the secret room of Xining Mansion all day today, looking for any clues about Su Qingcang.

But the strange thing is that when he was in Dongling, the intelligence clearly said that Su Qingcang came to Beiyuan, and Su Yizhi also said the same thing at that time, for some reason, there was no record of the Xining family at all.

Even if Su Qingcang came in quietly like them, after such a long time, the people of the four major families are not vegetarians, and it is impossible that no news has been revealed at all.

I'm afraid that Su Qingcang will encounter some danger.

When he was about to share these things with Su Tingcheng, he found that she was not in the mansion.

Ye Tantai saw the letter she left on the table, worried about what would happen to Su Tingcheng when he went to Yao Mansion, and was about to go to her, when he happened to meet Su Tingcheng who came back.

Ye Yutai spoke first: "You're back, do you want to eat together?" ”

Su Tingcheng nodded.

Only then did he remember that Su Qingcheng's throat seemed to be speechless.

A thousand words in my heart, I don't know how to speak.

He cautiously walked to Su Qingcheng's side and followed her, the child was gone, and she was the most painful one.

The two walked on the stone road of Xining Mansion one after the other, and Su Qingcheng didn't know what to do when he saw his cautious appearance.

If it was before, Ye Yutai would definitely stick to her as soon as he saw her.

She didn't think about how to face Ye Yutai.

But only by staying with him can she feel at ease.

Even if the two of them didn't speak, they could be quietly by his side, and Su Chengcheng felt at ease.

You don't have to think about the intrigues, and you don't have to think about whether you are approaching her with a purpose, that's enough.

"I've been checking on my father-in-law's news today."

Hearing this, Su Qingcheng looked up at him, some hope appeared in her eyes, and she also wanted to know where Su Qingcang was now.

Maybe this will unlock the secret of my mother's background.

Ye Yutai continued: "But I have searched through the correspondence between the entire four major families, and there is no news about him. Have you ever heard of a relationship between your father-in-law and the people of Beiyuan before? ”

Su Qingcheng shook her head, but she immediately thought that if her mother was from Beiyuan, then her father might be with her mother's mother's family?

He also came to Beiyuan for this matter?

But didn't Dongling's queen mother say that her mother might be a member of the Beiyuan royal family?

Could it be that the father and the empress are together?

Impossible, impossible......

Su Chengcheng immediately denied this idea, this is true. It's outrageous.

Ye Yutai considered that Su Chengcheng couldn't speak, and when he came out of the study, he specially brought her a portable brush and paper and handed it to her.

"If you have anything to say, write it down."

Su Qingcheng was moved in his heart, although he couldn't sign language, he also thought about everything for her.

She wrote: "Will the father be with the mother's mother's mother's mother?" ”

Ye Yutai tilted his head and looked at it, and said, "It's not that this is not possible. But I've been looking for a long time, and I haven't found any news about your mother, do you know who your mother's name is? ”

Only then did Su Tingcheng react, she, the daughter, didn't know her mother's full name.

"I don't know, my father never said that he hasn't mentioned anything about my mother to me since she died."

"In this way, your mother is likely to be a more important person in the royal family, which is why her affairs are kept so well." Ye Yutai Road.

What he actually wanted to say was whether her mother would be the twin sister of the empress who had never appeared in Beiyuan.

But considering that Su Chengcheng couldn't accept it, he still didn't say it.

"Do you remember when Yulan said that she came out with the national teacher?" Su Qingcheng wrote on paper.

"Well, I remember, is there anything between that?" Ye Yutai asked.

Su Chengcheng didn't know why she remembered this incident, and the more she thought about it, the more she felt that all this was not a coincidence.

"Can you take me to the secret room of the Xining family?" Su Chengcheng Road.

Ye Yutai nodded, he couldn't ask for Su Chengcheng to rely on him.

Although there are heavy guards outside the secret room of Xining's house, now that Xining Jianai and Xining Sedum are not there, it is not difficult for him to take Su Chengcheng in.

Su Chengcheng followed him to the back mountain of Xining Mansion, which was the first time she had come to this mountain.

Although I have lived in Xining Mansion for so long, I have been looking at this mountain, and I have never thought that the secret room of Xining Mansion will be inside this mountain.

"Where did you get in?" Su Chengcheng looked around very curiously.

Ye Yutai looked at this towering mountain and said: "This mountain is the secret room of Xining Mansion, it has been hollowed out inside, and there are many mechanisms, you will know it when you go in." ”

Su Tingcheng had worn the clothes of the maid in Xining Mansion before, so she was wearing that set this time.

She followed behind Ye Yutai, keeping her head down, avoiding eye contact with the guards at the door.

The guard stopped first and said, "Young Master Ye Sheng of Xining, you are not allowed to bring maids in here." ”

Ye Yutai said: "I'm not feeling well today, she is not an ordinary maid, Brother Sedum is not here, there are still a lot of things waiting for me to deal with, she is for me to recuperate." ”

The guard hesitated for a moment, considering that Xining Mansion did need to deal with a lot of things every day, and Xining Sedum had not appeared for several days.

For the sake of Ye Yutai's safety and the affairs of Xining Mansion, they finally let it go.

Su Qingcheng obediently followed behind him, but he didn't expect that the appearance was a mountain, but the inside was a labyrinth, full of mechanisms.

Seeing that there was no way out in front of him, Ye Yutai fiddled a few times on the wall, and another road appeared.

What's even more coincidental is that this is the solution of the mechanism, which was actually recorded in the books she read in her previous life.

How could it be such a coincidence?

The books the old man gave her turned out to be exactly the same as the layout inside!

At that time, she was still thinking that she had never seen such a layout in Nanye and Dongling, thinking that these things did not exist in the world, but were simply recorded in books.

I didn't expect to see it in the secret room of Xining's house.

The method of setting up various mechanisms, the direction of feng shui, and even the location of the keys......

She was amazed to find that the book was like a map of a large Xining family's secret room.

There are four such books in total, could it be that the other three correspond to Beili, Nangong and Dongyunjia?
