After sliding down by himself, the speed is much faster than the previous slow climb. This passage is not large, and when they want to stop, they can quickly stop by holding their hands and feet on the walls on both sides.

This made the five of them a lot easier, and they had a chance to rest, but their spirits were still tense.

And this process lasted for about half an hour, and Xiao Yang at the bottom suddenly exclaimed: "Boss, Miss Lin, Mr. Bo, we seem to be at the end!" ”

Several people immediately controlled themselves to slow down and stop.

Previously, in order to ensure the time to react in the event of an accident, several people kept a certain distance from each other, and this is where it comes into play.

After stopping, Kate asked, "What's down there?" Is there an exit? ”

Lin Wu also looked down, but unfortunately there were Kate and Zhang Shan's figures blocking her vision, and she couldn't see anything.

Knowing Suosuo's movement, Xiao Yang should have found a more convenient posture and then groped for something.

Zhang Shan urged him to speak quickly.

Xiao Yang hesitated: "Yes, there is an exit." It seemed to be a trapdoor, and there was a lock on it, in the shape of a toad, but I looked for a while, but I couldn't see where the keyhole was. ”

"Don't see the keyhole? What kind of lock is that, why don't you try to break it with a gun? Zhang Shan said directly.

Lin Wu and Bo Yuting above didn't see the appearance of the lock, they didn't know what the situation was, they didn't say anything when they heard it, and acquiesced to this simplest and rude way.

Xiao Yang felt the same, and found the gun.

Just as he was about to load it, Kate suddenly said, "Wait, you can't use a gun!" ”

"Huh? Why? Xiao Yang asked suspiciously.

Kate pondered, "You didn't see the keyhole, probably because it's an ancient lock, and the keyhole is basically hidden. So come up and see for me. I should be able to drive. ”

When Xiao Yang and Zhang Shan heard this, they responded, and Zhang Shan and Kate switched places.

But it was not easy for the two big men to switch up and down in this narrow passage, and it took a lot of time to succeed.

Lin Wu looked at their actions and said, "I remember, Mr. Kate has lived abroad since he was a child, but he didn't expect to know about Gu Suo?" ”

Kate exchanged words with Xiao Yang while distracting Lin Wu: "It's just a personal hobby." Besides, when you go out, you will be a little more, and you will not be overstretched when you can use it in the future. ”

Bo Yuting, who was at the top, listened to this, and judged that Kate had already exchanged with Xiao Yang, and he suddenly asked, "After Mr. Kate saw it, are you sure it's the ancient lock?" ”

Kate below took a closer look and didn't mind explaining to them: "It's indeed an ancient lock." This lock system is very special, it is a mixture of two kinds together, three open inverted pull locks. Specifically, the surface of the toad must be turned over in a circle, and the mechanism hidden in the toad's mouth will unlock the exterior to reveal the three-layer core lock inside, and then unlock this to completely open it. ”

"It's very intricately crafted, and the shell is so hard that a bullet may not be able to break it, but it will definitely destroy its internal mechanism, so that it really can't be opened again, and we will only be trapped here."

Xiao Yang was surprised and said, "Such a troublesome lock...... But you can't find the keyhole inside, right? We don't know where the key is. ”

"This lock system doesn't need a key, just unlock the three-layer lock inside, and it can be opened." Kate replied.

Bo Yu Ting above suddenly said again: "But listen to what you said, this lock should be very small, right?" Mr. Kate, can you see clearly? ”

Kate was concentrating on the inspection, and replied without thinking: "It's okay, I have a magnifying glass." ”

Hearing this, Bo Yuting didn't speak again.

Lin Wu instantly understood what Bo Yuting meant, and she immediately said, "Come down to the mine cave and bring a magnifying glass to do?" Isn't the equipment we use uniformly arranged? Mr. Kate's magnifying glass for himself is also out of personal hobby? ”

Kate below paused.

After a while, he continued to pick the lock, patiently explaining, "This time it's not because of personal hobbies. ”

"Oh?"

"The contemptible person is the person in charge of the mine, and sometimes he has to check the stone content and follow the experiment. A magnifying glass is just a necessary tool. ”

After Kate finished speaking, Xiao Yang and Zhang Shan above followed and spoke.

"That's right, that's right, our boss has worked hard!"

"It turned out that at that time, he was busy every day without touching the ground, and he had very little time to rest, basically doing all kinds of things, and he knew a lot."

Saying this, the two are simply full of admiration for Kate.

And Lin Wu and Bo Yuting only echoed and didn't say anything.

It can be seen that the ancient lock should be quite difficult to unfasten, Kate took a full twenty minutes, and with a soft "click", his relieved voice sounded: "Okay, untie, now you can go out." ”

But before anyone else could say anything, his abrupt and serious voice suddenly sounded again.

"Being able to use this kind of ancient lock shows that the place you see after going out is not ordinary, and it may be very dangerous. Be careful, everyone, and don't take it lightly! ”

Xiao Yang disagreed: "Boss, there are a lot of dangers encountered in front, no matter how dangerous it is, where can it be dangerous?" ”

"Yes, boss, open it up and get out, I'm going to suffocate here, and I need to breathe urgently!" Zhang Shan Road.

Lin Wu heard Kate below sigh, took off the ancient lock and put it aside, and then opened the small trapdoor.

However, he did not open them all at once, but first opened a slit and shone it with a flashlight.

After a few seconds, Kate spoke: "It seems to be a confined space below, and I haven't seen anything unusual for the time being." But our position seemed to be on the ceiling, at least three or four meters above the ground. So, I'll make a fixing point, and we'll go down the rope. ”

All four of them said hello.

Kate opened the trapdoor, took out the rope from her bag, tied it to the trapdoor as a fixture, he went down first, and fell to the ground in a few seconds, and it was a while before he was reminded that he could start playing.

Xiao Yang and Zhang Shan followed.

Then there is the forest fog.

Lin Wu was about to go down when he was suddenly stopped by Bo Yuting.

She looked up, "What's wrong?" ”

Bo Yuting lowered his voice meaningfully and said: "Follow Kate closely, don't stay away from him, he should be the safest by his side." ”

Lin Wu understood that Kate was really a little strange, but he couldn't tell where it was.

He even brought a magnifying glass with him when he went down to the mine, but they didn't come down to measure stones, so what was the use of bringing a magnifying glass? Unless he's sure he'll be able to use it.

That is, it has to do with the real purpose of their group.

"Miss Lin?" Kate called her below, with a worried voice: "Why can't you come down yet?" Is something wrong? ”

"Let's go down."

Lin Wu answered, pulled Bo Yuting to reassure him, and then jumped down.
