"That's right." Just as Duan Ming was thinking, Xing Qianqiu looked at the soldiers on the side: "I see that this cave entrance is not far from the main mine, has no one found this place for so long?" ”

"Not really." The soldier shook his head: "It's not just the miners, our Ordnance Department will also come in every night to check around to see if anyone is missing in the pit." But never found this place. ”

"Is this pit really natural?" Listening to the soldier's words, Xing Qianqiu's brows furrowed slightly.

"Is it possible that someone dug this cave first and then blocked the entrance?" Li Wan'er said.

"The key is who can do this kind of thing quietly." Xing Qianqiu shook his head: "Such a big cave is definitely not something that can be dug in a day or two, who can dig here every day without anyone knowing, and no one will find out?" ”

"And, how do you get out of the rocks, sand, and minerals here?"

"Well, that's a problem." Li Wan'er nodded.

"Maybe it's not like there's no way out." Duan Ming said suddenly.

As he spoke, Duan Ming searched the situation in the cave little by little, constantly touching the ground around him.

Xing Qianqiu and Li Wan'er saw Duan Ming's movements, and at the same time thought of a possibility, and searched together with Duan Ming.

In this way, Duan Ming and the three of them searched inch by inch under the surprised gaze of the soldiers, and did not miss an inch of land.

Just when the soldier felt a little bored, Li Wan'er's eyes suddenly lit up: "Found it!" ”

Duan Ming and Xing Qianqiu heard Li Wan'er's words, and at the same time, they looked at each other for a while, and walked over quickly.

Li Wan'er squatted down and carefully brushed aside a withered flower on the ground, revealing a wooden plank hidden in the dirt.

"No wonder flowers are planted here." Duan Ming came to the wooden board and sneered: "In order to cover up the traces of this." ”

"I'll come." Xing Qianqiu said in a deep voice, grabbed the wooden board with both hands, and lifted it hard, directly lifting the wooden board, revealing a dark hole underneath.

The entrance to the cave is not large, but it is enough to accommodate the stone of the dragon pattern stone carving.

"It seems that the excavation of this cave, as well as the transportation of dragon pattern stone carvings, all came in through this cave." Duan Ming said in a deep voice.

"Let's go in and have a look." Xing Qianqiu said that he was about to go inside.

"Wait." However, Xing Qianqiu's movements were blocked by Duan Ming, and he saw Duan Ming look at the stunned Ordnance Division soldier, and said in a deep voice: "Please take us to see your director." ”

"Okay." The soldier nodded repeatedly.

Walking out along the pit, Xing Qianqiu patted Duan Ming's shoulder, deliberately took a few steps behind, and asked in a low voice, "Why didn't you go in just now?" ”

"It's not the time." Duan Ming said: "First, if the exit of this cave is the other party's lair, can you escape with your whole body just by commanding you with punishment?" ”

"Well, I can't." Xing Qianqiu thought for a moment and shook his head.

"That's right, if you're not sure where the exit is, it's like looking for death to go in and investigate." Duan Ming said, "Then second, how far away is that cave from this main pit? A wall apart. ”

"What do you mean?" When Xing Qianqiu heard Duan Ming's words, he was stunned for a moment, and then his eyebrows suddenly raised: "...... you suspect?"

"Hmm." Duan Ming nodded: "To be able to find the location of the main pit so accurately, and on the basis of digging such a large cave without opening up the main pit, do you think there will be no one?" ”

"So, whether it's absenteeism or someone from the Ordnance Division, there must be someone here who is related to the people behind the scenes." Duan Ming said in a deep voice: "The three of us come here and the target is too big, it is difficult to ensure that the other party does not find out, if someone seals the exits on both sides when we explore the cave......"

"Then we will be suffocated to death inside......" Li Wan'er gritted her teeth and said.

"That's right, so the best way now is actually to contact the people in Spiegel as soon as possible, only they can be trusted." Duan Ming said.

"But in that case, shouldn't we go to Spiegel now? Why go to the Director of the Ordnance Division? Li Wan'er asked again.

"Because my purpose is to startle the snake." Duan Ming looked left and right and said, "Although it will be safer for us to take the initiative to find someone from the Spiegel Division, I am afraid that the effect is also the lowest." ”

"If the exit of this tunnel is not connected anywhere, then what good is it if we find the tunnel?" Duan Ming said: "We don't know who opened the tunnel, and we don't know who the spies in the pit are. ”

"But now that we're out of here, how long do you think this will spread throughout the mines?"

"For how long?" Xing Qianqiu looked at the soldiers of the Ordnance Division who were constantly greeting people, and the corners of his mouth twitched slightly: "It's only half an hour." ”

"That's right." Duan Ming nodded: "Whether that spy knows or not, we have discovered that tunnel, we will definitely know within half an hour." ”

"But it's daytime, the miners need to mine, the Ordnance Department needs to patrol, and it's impossible for anyone to leave silently, and it's impossible for anyone to go out and report the news."

"So what's the most likely thing this person is doing right now?"

"If it's me." Li Wan'er pondered for a moment and said, "First go to confirm whether the tunnel has really been found, and then destroy the tunnel to avoid exposure." ”

"Exactly." Duan Ming nodded: "But you're talking about you, judging from the reaction of a normal person, that person should be flustered as soon as he knows the news." He will do everything he can to escape. ”

"Go and ask the people behind the scenes what to do, how to do it." Duan Ming said: "But as I said before, it's not easy to leave here now, so what is the best way for him to leave as quickly as possible?" ”

"Get out of the tunnel!" Xing Qianqiu said in a deep voice.

"That's it." Duan Ming nodded: "So, old punishment, you need to secretly go back and hide now, if someone tries to enter that tunnel, it will prove that person is a spy." ”

"Remember what that person looks like, but don't let him out."

"I'll ask Rui'er to leave here first, contact Lao Xu, set up defenses at the foot of the surrounding North Mountain, and if I find traces of that person, I will follow them and try to catch a big fish."

"At the foot of the North Mountain?" Li Wan'er didn't understand why Duan Ming would say that.

"The cave is on the north side of the main mine, and since the other party has an accurate location, it will inevitably pick the nearest location to make a hole." Duan Ming said: "Therefore, I will definitely not choose to be on the south side of the mountain, and most of them will choose to be about halfway up the mountain." ”

"After all, the halfway up the mountain is not too high, the height difference is not very large, and there will be fewer people passing by."

"The best effect will undoubtedly be achieved by arming at the foot of the mountain on the north side."

"I see." Li Wan'er nodded......
