Gu Xin was a little distressed, he didn't expect Guan Jianhua to bring a woman by his side.

In the past few days, Guan Jianhua has gone out every night and came back in the early morning, is he having a tryst with this woman?

What surprised him even more was that this woman actually knew quite a bit about diving. - Of course he didn't know, in fact, Guan Jianhua had been teaching the woman to dive for the past few days.

Looking at the woman who was following Guan Jianhua, Gu Xin began to guess her origin and details. It's a pity that he couldn't figure out why he couldn't figure it out even if he wanted to break his head.

And Gu Xin's distress is also here, because he is now walking in a cave with Guan Jianhua, and he can't pass any information to Qi Yu at all.

The cave should be very large, and the flashlights in the hands of a few people can't tear through the surrounding darkness at all, let alone see the cave walls. However, the roof of the cave is not very high, and the flashlight can barely shine on it, so it should be about 30 meters.

"Boss, how far is it? It's so Nima black! A bodyguard asked.

"Follow me, don't run around, don't blame me for not saying hello to you if something happens!" Guan Jianhua didn't look back, snorted coldly and continued to walk forward.

Gu Xin didn't say a word, and didn't squint, he followed closely behind Guan Jianhua, and let the few bodyguards behind him mumble in a low voice.

"Hold the grass, Lao Tzu is the first time to come back to this kind of place, Nima is ridiculously big."

"Do you think there will be any beasts in there?"

"Idiot, how can there be fierce beasts in this kind of cave, let's worry about your feet, the long worm likes this environment the most!"

As soon as the words fell, several people immediately shone their flashlights on the ground.

"Yangzi, you shut up with Lao Tzu, don't be surprised, just listen to the boss." It was the head brother of these bodyguards who spoke.

"Brother Gui, I'm worried that I have a life to make money and no money to spend!" Although Yangzi kept his voice to the lowest, Gu Xin still heard it, and couldn't help but feel a little funny in his heart, what a rabble!

"Ah Xing, how big is this place?" The woman who followed Guan Jianhua finally spoke.

Since Guan Jianhua came back with the woman, Gu Xin had never heard her speak, and this was the first time he had heard her speak.

"I don't know the specifics, it's big anyway." Guan Jianhua said with a smile.

"What if someone else comes in?"

"Someone else coming in?!" Guan Jianhua suddenly let out a smug laugh: "It's easy to get in, but it's not so easy to get out!" ”

"Will you get lost?"

"You don't ask this, in a word, except that we can come and go freely, once other people come in, basically don't want to go out!" Guan Jianhua's tone was full of confidence.

Hearing this, Gu Xin's heart moved, and his face changed, but the flashlight in the dark could not make people notice the change in his expression.

Could it be that there are a lot of mechanisms here? Gu Xin said secretly.

There seems to be no pattern along the way, except that Guan Jianhua asked everyone to follow him, Gu Xin didn't see anything unusual.

The cave hall is so big, what does he rely on to judge the direction, because no matter how you look at it, Guan Jianhua doesn't look like a fly without a head.

Suspicion is suspicion, but Gu Xin didn't immediately use a flashlight to shine around, a frightened bird like Guan Jianhua would arouse his suspicion if he was not careful, so he began to pay attention to Guan Jianhua's feet.

Although the floor of the cave hall is not very flat, it is relatively dry, and there is no dust to be seen, except for some scattered gravel, there is not the slightest abnormality.

Even if someone walks on this kind of ground, it won't leave any traces!

This place is indeed very ordinary, so ordinary that ordinary people can ignore its details.

However, Gu Xin is not an ordinary person.

Therefore, after looking at it for a while, he quickly discovered the pattern: Guan Jianhua did not walk in a straight line, and every time he saw a stone with sharp corners, he would turn to the direction where the sharp corners of the stone were pointing.

Unless you look closely, it's hard to find this stone with sharp corners among the countless rubbles.

These stones don't look any different from other stones, the only difference is that the sharp corners are much longer than normal stones!

Guan Jianhua's walking speed is not slow, which shows that he is familiar with everything here, and he is not very careful to search for the kind of sharp corner stones, just very casually. Therefore, if you are not very careful, you will not be able to discover these details at all.

Gu Xin began to worry that if the people behind him came in and couldn't find out this secret, nine times out of ten they would be tricked. Although he didn't know what kind of security measures Guan Jianhua had set up, judging from the key to being so careful, it would definitely not be so simple!

But in this situation, Gu Xin has no way to pass on the information: in front are Guan Jianhua and the others, and in the back are several bodyguards, any unusual behavior will arouse their suspicion!

Gu Xin thought as he walked, thinking hard about countermeasures.

Thinking about it, he suddenly remembered that before leaving, Qi Yu gave him a small cloth bag that was not big but very heavy, the size of a fist, and it seemed to be filled with fine sand!

Gu Xin remembered very well that his eldest brother, who looked very unreliable, still didn't take things very seriously when he handed them over to him, but just joked that this was a clever plan he had prepared, and if he encountered a problem that he couldn't solve, he would prick a small hole in the bag.

Thinking of this, Gu Xin's heart jumped wildly: the eldest brother gave him this bag of fine sand so that he could use it to guide the way in the cave!

It's been a long way to go, and it's too late if you don't act.

Gu Xin didn't think much about it, and immediately put his hand into his pocket.

But as soon as he touched the small cloth bag, he immediately smiled bitterly in his heart: Big brother, although you have no last resort, but at this time, where can I find something to pierce it!

What's even more tragic is that Gu Xin usually loves to be clean, and he trims his nails well every time, so even if he wants to use his nails to break the cloth bag, it is not possible, and if he takes it out and bites it, these people around him will definitely see it.

Just when Gu Xin felt a little desperate, his fingers touched a different place on the surface of the cloth bag - it was very similar to duct tape!

Gu Xin was overjoyed in his heart, and Zhuge Kongming was Zhuge Kongming!

Then, Gu Xin paid attention to the people in front and behind and found that they didn't care.

The flashlight was meant to be used for lighting, but everyone had one in their hand, which helped a lot - if it wasn't deliberately illuminated, the light was just right for the person next to them to see the front of the person holding the flashlight!

Guan Jianhua and the others walked in front without looking back, and the few people behind could only see Gu Xin's back.

This condition is really amazing!

Thinking about it, Gu Xin immediately took out the cloth bag, quickly tore off the tape paper on the cloth bag, and secretly held it in his right hand holding the flashlight.

When I touched the place where the tape was torn off, there was a very small hole there, and the contents began to slowly flow out!
