The next few days.

Qingyin regularly treats Si Yunling's leg disease with acupuncture, watching the man stand for more and more time, and every step he takes becomes more and more stable, the sense of accomplishment in Qingyin's heart is simply indescribable.

The regret left by her comrades-in-arms was finally fulfilled in Ah Mo, which made her feel extremely relaxed, as if she had let go of the heart disease that had been bothering her.

But on the other hand, the light tone is undoubtedly restless.

Because she found that this underground castle did not have the existence of core chips.

In the past few days, she has visited the castle again and again, because she is worried that the distance of the bracelet is not long enough, she will miss something, so after Amo's leg disease improves, she changed the number of needles to the one at noon every day, completely vacating the night time, and then taking advantage of the dead of night to carefully search for it again through the secret passage of the castle.

Can be turned out .... Still nothing.

What's going on?

Could it be that the information Sang Mian gave her was wrong?

Could it be that the core chip is not in Sijia at all? ?

The other side.

Huge study.

The man's blue eyes looked at the surveillance video while listening to the white housekeeper's reply, and his face was gloomy.

"Master, I'm pretty sure Miss Light is no less familiar with this underground castle than any of us, and I even suspect that Miss Light is more familiar with this place than we are." Different from the gloomy face of his master, the white housekeeper couldn't hide his excitement and curiosity in his eyes, at this time it was completely different from the calm and old appearance on weekdays, but a face of gossip and curiosity.

You must know that this underground castle was built by the former head of the Si family for his wife!

Everyone actually thinks that the biggest capital of the underground castle is gorgeous and magnificent, but only a few people know that the real and most brilliant place of the underground castle is the hundreds of intricate hidden tunnels hidden in the depths of the castle and buried with mechanisms.

He is the old man of the Si family, and when he was young, in order to thoroughly study the entire underground castle, it took him a whole month to clear all the secret passages, exits, forks, and mechanisms in the castle.

But Miss Qingyin is good, obviously it is the first time to come to this underground castle, but she knows all the secret passages of the underground castle well, and the elusive figure makes him really shocked.

After realizing that Miss Light Sound would disappear inexplicably in the room, the master asked him to quietly set up a surveillance at the entrance of the secret passage in Miss Light Sound's bedroom.

It's okay if he doesn't set it, this one, he almost didn't stare out of his eyes.

In the surveillance video, Miss Light Voice skillfully avoided all the mechanisms, opening the paths of different secret passages as if she was walking in her own back garden, if he hadn't seen it with his own eyes, he would never have believed that a person who came to the underground castle for the first time would have walked the secret passages so smoothly.

As soon as the old man's words came out, the man at the table couldn't help but frown.

Ayin really has a great connection with her great-grandmother, otherwise how could she be so familiar with this castle related to her great-grandmother?

If he hadn't wanted to fall asleep in the middle of the night but found that the person was not in the room at all, he would never have thought that Ayin would have such a mysterious side and know so much about this castle.

At first, he just wanted to find out where Ayin had gone at night.

But the more he checked, the more frightened he became.

Because.... He couldn't find anything at all.

Except for knowing that Ayin would disappear into the bedroom inexplicably and appear in the bedroom inexplicably, he couldn't find anything!

Secret Path!

Ayin actually knew that there was a secret passage in the room?!

So he instructed the white butler to set up invisible surveillance on the main path of the dark passage.

But even so, Ayin would suddenly disappear at a certain corner, and then inexplicably appear on the main path of the dark passage on another floor.

He was shocked.

Ayin was more familiar with the underground castle than he had imagined.

It is not even an exaggeration to say that there are some secret passages that he, the current head of the family, does not know!!

But what shocked him even more was why did Ayin appear in the dark passage in the dead of night?

What does Ayin want to do?
