Quietly observing the entrance of the entire secret room, Bai Zi'an stared at it with sharp eyes, as if he was staring at the enchantment at the bottom of the cliff before.

Because the Mu family has always been very cautious, Bai Zi'an has not been able to detect that anyone has entered or exited here in the past few days, which also makes the process of entering this secret passage extremely difficult.

"Host, how are you going to get in?"

Of course, it is impossible for the system to help at this time, the only thing it can do is to give Bai Zi'an some help when he uses the luck value to exchange for items in the mall, and there is nothing else to do.

Otherwise, if the system violates the rules, I am afraid that it will no longer be able to stay with the host.

"I don't know yet, but I don't need to worry too much, after all, as long as people come in and out, there must be some traces of this place, after all, they want some natural dust to accumulate here over the years, and no one needs to clean it. ”

When he said this, Bai Zi'an seemed to understand something, his eyes lit up slightly, and he pointed to the entrance of the secret passage in front of him and said, "Can you help me find out if there are any other traces of existence here, such as whether there are traces left by fingerprints that have been touched by anyone." ”

If it is placed in this extremely backward place, no one should be able to think of such a thing as fingerprints, but Bai Zi'an is different.

After all, he came from the advanced modern era, where fingerprint investigation has become a reasonable and normal thing, so Bai Zi'an wanted to know if he could learn some other secrets if he used this method.

"Host, please wait. ”

After hearing Bai Zi'an's request, the system quickly began to help him investigate the relevant content.

After all, Bai Zi'an also said that it was just a matter of consuming some qi luck points, but after solving the entire Mu family, he could get more qi luck points, of course, he didn't need to worry about anything at this time.

"Host, after system detection, it can be seen that there are indeed several traces of fingerprints on the stone cliff in front of you, but how to open the secret passage still needs to be explored by the host itself. ”

Bai Zi'an was already very satisfied with this situation, after all, he was worried at the beginning that there was no way to investigate the relevant evidence, and now he can provide him with some clues about fingerprints, which is already very difficult.

"Tell me about those clues so I can get to know his content faster. ”

At the request of the host, the system unfolded a processed image in front of Bai Zi'an, which indicated the location of several fingerprints and the traces left by other animals that had crawled.

The traces of animal crawling are green, while the traces of human contact are red, and the fingerprints are highlighted in red.

"What's the deal with all this red?"

Bai Zi'an frowned slightly, and his expression was more vigilant.

"Please also rest assured that this is a garden after all, and there are always a few other people coming and going, and these are the traces left by those people who accidentally touched the rocks when they came by. ”

Since this is the case, Bai Zi'an naturally won't pay too much attention anymore, but just focused on the few highlighted reds in front of him.

"This inconspicuous stone has the most fingerprints, and it seems that you only need to explore here to understand the way to get in. ”

Bai Zi'an had seen a lot of designs about the secret room on TV, so he already had an idea of how to use this small stone.

But it occurred to him that the secret passage was under the garden, and if he touched the little stone lightly, or twisted it, and there was a loud noise in it, he would not be exposed.

"Is there a soundproof barrier that can shelter me from the wind and rain here? ”

After the system heard Bai Zi'an's words, it immediately followed his request and explored here.

After understanding the system, he quickly used 100 luck points to exchange a soundproof enchantment for Bai Zi'an.

"Host, please rest assured, this soundproof barrier can last for 5 hours, presumably after the host returns, this barrier can also bring some protection to the host. ”

It's a pity that this thing is disposable and can't be recycled, otherwise Bai Zi'an wouldn't let him waste 5 hours here in vain.

"Okay, if that's the case, then I don't need to say anything more, just follow the previous arrangement!"

"I'm going to enter this place, take care to help me set up the barrier, but don't let anyone else notice what I'm doing. ”

Hearing that the system responded to his request, Bai Zi'an nodded with satisfaction, and then, according to his guess, after carefully observing the small stone, he gently dropped his hand on the stone and twisted it vigorously.

Sure enough, after being blessed by Bai Zi'an's spiritual power, the stone was gently twisted, and according to the direction of the fingerprint drag, Bai Zi'an successfully opened the entrance of the secret passage.

"If I go in, there should be a way to close this secret passage inside! Otherwise, the sudden appearance of such a big hole here will definitely arouse the suspicion of others, won't it?"

The system doesn't give a specific answer, but it doesn't agree with it.

"Then I'm going down. ”

After saying this, Bai Zi'an quietly walked into the secret passage.

The secret passage is very dark, but the distance from the Mu family here is too tight, even if Bai Zi'an has a heart, he can't take out any lighting items at this time, otherwise once he is discovered, it will bring him a catastrophe.

After all, that barrier could be separated by a loud sound, but it could not be blocked by a bright light.

In the middle of walking, making sure that he had stepped into the bottom at this moment, Bai Zi'an took out the night pearl that he had already prepared at hand and carefully observed the surroundings.

There was still an hour inside that was exactly the same as the small stone on it, Bai Zi'an saw this, so he did not hesitate to twist the small stone, and sure enough, the hole that could still see a little moonlight was slowly covered again.

Bai Zi'an said secretly to the system in his heart: "I'm a little lucky, just now I arranged a soundproof barrier, this mechanism, although the sound is not loud, but at night it can still attract some attention from others." ”

After saying this, Bai Zi'an didn't pay attention to what kind of feedback the system was going to give, but walked forward gently.

In order to prevent any accidents, he had already put spiritual power charms on his legs, so that he could walk here as light as a swallow and never leave any footprints.
