Xiong Yu shook his head and said in a low voice, "What if they kill each other? ”

Bao Sanjin was slightly stunned, and didn't ask any more, he vaguely guessed what Xiong Yu was going to do.

Han Tianqi went for about ten minutes, and then he came back directly with someone, with a hint of joy that could not be concealed in his eyebrows, it seemed that he should have already talked with Leng Bingyan.

Han Tianqi stood at the door of the cave and shouted, "Come here." ”

Liu Quan escorted Xiong Yu and his party to the entrance of the cave, and then walked in with Han Tianqi.

When Xiong Yu was at the entrance of the cave, he saw that not far from the entrance of the cave, there was also a pile of snake skins, which were thickly piled up.

The people of the Waden family and Han Tianqi were a little surprised when they saw these snake skins, they had already encountered a lot on the road before, but the entrance of the cave did not attract their attention at all.

Xiong Yu's eyes narrowed, and he became more and more sure of the thought in his heart from the time he saw this mountain.

The cave is pitch black and there is a lot of space inside.

After walking about 500 meters, a huge natural mountain space appeared, the size of a dozen indoor basketball halls.

The people brought by the cold flame are all here, and they have lit a few torches and lit up a lot of this place.

The locksmiths brought by the cold ice flame were all in front of a stone gate in the southeast of the hall, measuring and groping for something.

Leng Bingyan saw Han Tianqi walking in with Xiong Yu and his party, and said in a cold voice: "Let your people take care of them, and if there is any change, kill them directly." ”

Han Tianqi said lightly: "You don't have to worry about this, how long will it take for the craftsman you brought to open the door?" ”

Leng Bingyan glanced in the direction of the locksmith and the door, and said, "This door is very cleverly designed, once the original key is inserted, or if the door is damaged, the mechanism behind this door will be triggered. ”

Han Tianqi asked: "Why don't you use explosives to explode directly, the previous people's organs were average, and they can't be compared with the current weapons at all." ”

Leng Bingyan said lightly: "This is the interior of the extinct volcano, although this volcano has not been active for thousands of years, but the magma inside the volcano has always been active, once this door is damaged, the mechanism inside is triggered, and all the treasures inside will be pushed into the volcano by the mechanism and turned into ashes." ”

Han Tianqi's eyes narrowed and said, "There is still such a mechanism?" However, even if this is the case, there were not many security mechanisms in ancient locks, and it should not be difficult to find a locksmith to open this lock. ”

Leng Bingyan said: "This lock was made by a palace locksmith who escaped from the Qing Empire in the past, and his lock has always only had one key, even if it is a modern senior locksmith, he may not be able to open it." ”

After Leng Bingyan finished speaking, he didn't pay any attention to Han Tianqi, but walked to the huge stone door and watched the four most powerful locksmiths from the world open this lock.

They spent half an hour in front of this stone door, using many strange tools to measure and observe this stone door, but they did not succeed, and their faces became more and more heavy.

Half an hour later, one of the oldest locksmiths who took the lead put down the tools in his hand and said to Leng Bingyan: "This lock does not have the original key and cannot be opened. ”

Leng Bingyan was a little surprised, and asked, "Can't even Zhong Lao, you open it?" ”

The old man known as Zhong Lao shook his head and said, "It's not that it can't be opened, this stone door has been designed with a lot of mechanisms, once we unlock the process, there is a little mistake, it will trigger the mechanism behind the door, causing unpredictable consequences." ”

Leng Bingyan frowned and asked, "Isn't there a way?" ”

Zhong Lao thought for a while and said: "If you want to open this door directly, there are few ways and the risk is great, but ......"

Seeing that Zhong Lao hesitated, Leng Bingyan immediately asked, "But what?" ”

Zhong Lao said: "Regarding the locksmith of the Qing Dynasty who made this lock, I have carefully studied his deeds and found a habit of him, that is, when he designed the mechanism in this treasure and made the lock, he would leave a secret door to escape. ”

Leng Bingyan didn't understand a little, looked at Zhong Lao suspiciously, and asked again, "What escape secret door?" ”

Zhong Lao said: "When some tombs or treasures were built in ancient times, in order to keep it secret, the craftsmen and designers involved in the construction would be buried together, and the designers and some shrewd craftsmen would be aware of this problem, so they would quietly reach an agreement in secret, outside the main gate, open another secret door, in order to escape when the funeral was held." ”

Leng Bingyan understood, his cold eyes lit up, and he asked, "This treasure also has a secret door?" ”

Zhong Lao nodded and said: "According to my understanding of the locksmith, there will definitely be, because as a locksmith of the Qing Dynasty, he should have been buried with him after participating in the construction of the Qing Emperor's Mausoleum, but he left the Qing Emperor's Mausoleum alive and fled overseas, which shows that when he built the Qing Emperor's Mausoleum, he left a secret door, and he escaped from the secret door, and he survived." ”

Leng Bingyan hurriedly asked, "If there is really a secret door, where will it usually be?" ”

Zhong Lao glanced around, then recalled the overall direction and characteristics of this mountain, and said: "According to past experience, the secret door should be about a hundred meters northeast of this cave, and there is no lock on the secret door, you can enter directly, but it is relatively hidden. ”

Leng Bingyan said directly to Han Tianqi: "You take your people here to watch Xiong Yu and his party, let's go out to find the secret door." ”

When Han Tianqi heard this, he immediately squinted his eyes and said, "Liu Quan, you take two people here to watch them, and I will go out with Leng Bingyan to find the secret door." ”

When Leng Bingyan saw Han Tianqi say this, he also understood what Han Tianqi meant, obviously afraid that she would swallow the treasure alone.

Leng Bingyan glanced at Han Tianqi lightly, and did not refuse, and immediately walked towards the outside of the cave with the people of the Waden family, and Han Tianqi also walked out with people.

Xiong Yu secretly said hello to Sun Lan and Wang Yunxiu in the team, asking them to hide their identities, stand still, and not expose themselves.

Both of them also nodded secretly, agreeing with Xiong Yu's arrangement.

After the others left, the cave instantly fell silent, leaving only Xiong Yu and his party of five people, as well as Liu Quan and the two people he carried.

The cave was quiet, and Liu Quan and his party held lamps and guns, facing Xiong Yu and his party, full of vigilance.

Xue He, who had never spoken, suddenly spoke: "The Qing Dynasty locksmith they said designed this lock has a very special title, called mint, right?" ”

Xiong Yu was slightly surprised and asked, "How do you know?" ”

Xue He smiled slightly: "I used to read a little more books, and when I read in an ancient book, his man-made lock only has a key, and the key has a mint grass mark on it." ”

Xiong Yu nodded and said, "Not bad." ”

Xue He said: "I went to the stone gate to take a look, I heard a long time ago that this locksmith made a lock is peerless, and today it is rare to see a real handiwork." ”

Xue He said as he walked towards the stone gate.

Liu Quan's brows furrowed, but seeing that Xue He was just an old man, he didn't care, let alone stop him.

Xiong Yu secretly touched the key to the ceramic with mint grass mark in his arms, and said, "I'll take a look too." ”

Seeing this, Bao Sanjin, Lu Chang and Yue Zhong also walked over.

Liu Quan suddenly shouted: "If you move, I will kill you." ”

Bao Sanjin turned around and said, "Calm down, let's just look at this door, you don't have to be nervous." ”

Liu Quan and the other two people held guns in their hands and pointed them at them, and didn't say anything, although there were only three of them in the cave, but there were all their people outside, not to mention that Xiong Yu and his party didn't seem to have any strength, and there was no threat on the surface.

If they just looked at the door, they wouldn't have to stop it.

Bao Sanjin walked to Xiong Yu's side and asked in a low voice, "Do you want to kill them?" ”

Xiong Yu shook his head and said, "Don't worry, don't alarm the people outside, I have my own way." ”
