Looking at the swarthy thief hole, Li Bing couldn't help but ask in surprise: "I've heard and seen the ancient tomb where the mechanism is hidden in the tomb, how can fine sand prevent theft?" ”

Qian Yiduo said 'um' and said in an awe-inspiring tone: "Don't underestimate this fine sand, because it is screened, the particles are very fine, and it has been exposed to the sun, so the flow is very large." When someone digs a robbery hole and tries to enter the tomb in vain, a large amount of fine sand immediately flows into the excavated place, and it is instantly filled up, so that the robbery hole that the tomb robbers have dug with all their strength and hollowing out will instantly come to naught. ”

He said with a look of fascination and fear: "If the tomb robbers are unwilling to let go and insist on continuing to dig, then a large amount of fine sand will immediately flow over and bury the tomb robbers alive in the fine sand." ”

Li Bing and Zhang Yuanshan were taken aback and sighed: "It's really amazing, it seems that it is really set up by a master." ”

Qian Yiduo sighed: "It's just fine sand to fill the tomb, it's not too powerful." Some burial chambers are filled with a large amount of rubble, and although they do not have the fluidity of fine sand, a large amount of rubble can still prevent excavation, and it may also collapse, which can also bury tomb robbers. This tomb has both, and the fine sand is mixed with a large number of sharp and sharp gravel chips, which can not only flow and bury the tomb robbers, but also the sharp edges and corners of the gravel chips are like a knife, cutting the tomb robbers alive. ”

As soon as Qian Yiduo finished speaking, he was so surprised to see that Li Bing and Zhang Yuanshan couldn't say a word. All three of them understood that since the White Tiger Seventh Demon had led them here, they would have to enter this ancient tomb in order to get clues about their next move.

Li Bing was stunned for a while, and asked Qian Yiduo: "Brother Qian, how do you generally deal with this kind of quicksand tomb?" ”

Qian Yiduo said slowly: "If it is a single thief, he will generally give up when he encounters this kind of tomb." Even if a group robs a tomb, when encountering this kind of tomb, they have to first build a house at the entrance of the robbery hole or pretend to develop minerals at the construction site to cover people's eyes, and then continue to transport out the fine sand until the fine sand in the tomb is emptied. ”

He sighed and said, "However, the one who can build such a mechanism must be a large tomb, and the fine sand in the tomb is often dozens or hundreds of tons. Therefore, most tomb robbers, when they encounter such a situation, must give up. ”

Li Bing said helplessly: "How is this good? Entering the tomb is very important to us, but there is no good way to think of it! ”

Zhang Yuanshan suddenly said: "Li Bing, who do you say this ancient tomb will design?" Whose tomb is it? ”

Li Bingyileng: "Being able to design such an ancient tomb is related to the Qianling Tomb, which is probably Yuan Tiangang's handiwork." As for who the person in this tomb is, it is unknown, anyway, it should be before Yuan Tiangang or his contemporary. ”

Zhang Yuanshan thought for a moment and said: "Li Bing, since it was made by Yuan Tiangang, then we all know that this strange person in the early Tang Dynasty is a master of arranging organs. So, since he would have predicted that more than 1,300 years later, the destined person who cracked the secret of the Qianling Tomb would come here and would enter the ancient tomb to get clues, could he completely block the entrance to this ancient tomb? ”

Li Bing was stunned, got Zhang Yuanshan's revelation, thought for a while, and said happily: "Yes, Brother Zhang is reasonable. In this way, this tomb must have a mechanism to remove this quicksand. How does this mechanism work? It must not be inside the tomb, but outside the tomb. ”

Three ** hi, immediately look around on this basketball court-sized square platform. Even though they searched every inch of the grassless square platform, they didn't find anything unusual, and they couldn't help but be a little disappointed.

But Li Bing knew in his heart that since it was made by Yuan Tiangang, this mechanism must be very ingenious, and it was also to prevent people who accidentally broke into this place from inadvertently touching the mechanism!

He stopped, smoked a cigarette, frowned at everything around him, and his gaze rested on the only four boulders on the platform.

Li Bing's heart moved, and he called Zhang Yuanshan and Qian Yiduo, and the three of them exerted their efforts at the same time to push the boulder.

However, the boulder did not move at all under their combined push. The three of them tried their best, but they had no choice but to stop and gasp to recover their strength.

Li Bing looked around the boulder for a while, and vaguely felt that the boulder seemed to be a little uneven. He spread out his palms and stroked the surface of the boulder, and sure enough, he felt something unusual, as if it had been artificially carved.

Li Bing hurriedly took the flashlight from Zhang Yuanshan's hand, and when he looked at the tentacles, he couldn't help but feel a burst of surprise: there were a few big characters engraved on the surface of the boulder!

Although he found the big characters, Li Bing knew in his heart that it must be related to this ancient tomb mechanism, but he didn't know the words on it. When he was anxious, his eyes caught a glimpse of the car parked under the square platform, and his heart moved, and he ran to the edge of the square platform and called Shi Liya.

After a while, Shi Liya also grabbed the rope with difficulty and climbed onto the square platform. Li Bing said solemnly: "Sister Shi, there is a very powerful ancient tomb on this platform. If you want to break the mechanism, the only clue is the words engraved on these four boulders. But I don't know any of them, I don't know if you, a top student in the history department, can recognize you! ”

Shi Liya didn't answer, took the flashlight and carefully looked at the four big characters on the boulder. After a long time, Fang Cai said in surprise: "This is the ancient seal style, and these four big characters are 'the essence of the green dragon'!" ”

"The essence of the green dragon?" , Li Bing was very surprised: "Isn't that exactly what the four elephants mean?" By the way, this boulder is located in the east of the square platform, do you remember whether the white tiger disappeared to the west of the square platform just now? Sister Shi, go and see if there is any inscription on this boulder in the west, whether it is related to the white tiger! ”

Shi Liya snorted, ran to the boulder in the west quickly, and sure enough, she found that there were really four ancient seals carved. She recognized it for a moment and read it softly: "White Tiger Soul!" ”

At this moment, the four of them couldn't help but be overjoyed. Shi Liya hurriedly recognized the words on the two boulders in the north and south, which were: "Spirit of the Vermilion Bird" and "Spirit of Xuanwu"!

Li Bing was overjoyed, and muttered in his mouth: "The left green dragon, the right white tiger, the southern Vermilion Bird, and the Northern Xuanwu correspond just to: the essence of the green dragon, the soul of the white tiger, the spirit of the vermilion bird, and the spirit of the white tiger!" That adds up to this: Soul Spirit! ”

Zhang Yuanshan heard Li Bing's chatter, and exclaimed, "Li Bing, I understand." It turns out that this is the tomb of the five elements, and the four elephants can give birth to the five elements. Then, the Qi of the Four Elephants that we have painstakingly gathered is the key to opening the tomb of the five elements. ”

Li Bing said puzzledly: "Brother Zhang, how do you think this is the Tomb of the Five Elements?" ”

Zhang Yuanshan said with a smile: "This is our Taoist theory, as a disciple of Maoshan, how can I not know the reason?" ”

Under the surprised and expectant gaze of the three of them, Zhang Yuanshan proudly said the reason why he thought this ancient tomb was the tomb of the five elements.
