Chu Xunyu and the three of them were wielding shovels and pickaxes, and they dug for more than two hours before they could find some signs, Mu Yuan dropped the shovel in his hand and wiped the sweat on his face, but his face was full of black coal foam, and he couldn't help but scold: "Ye Langzhong, you can't lose anything, pull us to dig a hole to play!"

"No way, I should find it soon. Chu Xunyu also spat on the ground, looked up, and saw that he was already a hundred feet deep from the end of the pit where he saw the copper tripod, and the shovel finally touched a black stone slab, so he threw the shovel aside, took out a water bladder and poured it, and handed it to Mu Yuan, "Take two sips and rest!"

"Done, found it?" Forget Chen jumped down from it, his own body and face were also covered with soot, and he had no trace of his former demeanor, and he was very curious when he saw the two of them stop, so he asked, "Found it?"

"Whether you find it or not, you can't do it anymore. Mu Yuan stepped on the stone slab on the ground with his foot, and said angrily: "This wild man is too tricky, this thing is dug all the way down, tired me, you are too, you just changed you to look at the wind, but I couldn't see your figure for half a day to change shifts, so lazy and lose your identity." ”

"I can't see a human figure yet?" Forget Chen pointed to his black nose with a smile, "I look in the mirror like this now, and I'm no less tired than you." ”

"That's not Ye Langzhong, I don't have to say that I know this Raush Zi formation, and I don't want to use the earth escape technique, I have to dig with brute force with my bare hands, good guy, make it look like this, whether it's or not, I'm not digging anymore, I'm tired to death." Mu Yuan angrily pointed his finger at Chu Xunyu.

It turned out that Chu Xunyu found the key from the pattern on the Ding furnace, and the big tripod placed next to the man was not placed randomly, but came from a formation in Chu Xunyu's medical family, called "Zhuan Yang Three End Formations", which is an ancient formation, which is Sun Simiao's "Yellow Emperor's Inner Canon" It is specially used to reverse the excessive yin qi in the body, and it is a fundamental formation that washes the marrow and cuts the veins, and changes the physique in one fell swoop, which is extremely profound, and the copper tripods that Chu Xunyu saw are actually arranged in this formation, but the spider is a cold thing, how to reverse the yin and yang, it is really incomprehensible, it seems that the means of the ancestor Qinglianzi are not something that he will be able to figure out for a while.

There are five doors to enter this formation, which are in charge of "yin, yang, life, death, and shock", there is a special attention to this, yin, yang, life, and death are naturally closely related to the medical Tao, yin and yang are all things, and life and death are defined to return, but there is a surprise door, which is specially left as a doctor, because many patients fall into a coma because of their injuries and serious conditions, so there is the establishment of this door, and the patient is awakened from consciousness. If you want to enter this formation, you have to enter from the Yin Gate and go out from the Yang Gate, Chu Xunyu thought about it in his heart, and the distance should not be too far, otherwise it would not alarm these spiders, so he mobilized Forget Chen and Mu Yuan to help him dig up the ground with his bare hands, but he couldn't use the technique, because he didn't know where this formation was, and there was no way to know what the mechanism was, so he dared to use the earth escape technique to crack the earth, in case he touched the trap in the formation, it was not a joke, so he had to dig all the way according to the direction indicated by Chu Xunyu, which was a bit of a gain.

As long as you dig the other side, there will be no problem, it stands to reason that the Yin Gate is the entrance, and it is impossible to place these spider copper tripods, only people who do not know how to dig on it for the coal mine will make the chicken and dog restless. Chu Xunyu looked down and saw that the material of the black slate was extraordinary, so he leaned down to watch it carefully, and wiped the slag on it with his hands, in addition to the usual "peep into the sky, longevity and prosperity" eight characters, there are also strange lines, Chu Xunyu used his fingertips to cross these lines for a long time, these patterns are extremely large, and have been extended to the stone slabs that are still buried in the soil, and the entire black slate is tightly sealed, like a whole, and there seems to be no place that can be opened.

Mu Yuan pouted: "Okay, don't tell me to dig in the wrong place, even if it's wrong, there's no way, I won't help you dig it, I'm tired to death." ”

"No, this is it. Chu Xunyu looked at the stone slab under his feet categorically and said.

"Oh?" Mu Yuan was stunned, "How can this get in?"

Chu Xunyu took out the remnant sword and stood vertically on it, his left hand suddenly held the blade, cut the palm, and let the blood drip down with the tip of the sword and condense on the stone slab, but after a while, he only saw that the blood stains on the black stone slab were actually swimming away on their own, and everywhere they went, they were all bright red as blood, and finally formed a big spider pattern, and the ear heard a "click" sound, and the stone slab began to open from the center of the spider pattern, revealing a black hole.

Sticking out his head to look, there was a dry breath coming from the dark hole, and Mu Yuanqi said: "Looking at the posture, at least no one has been here for hundreds of years, why is there no musty smell and moisture?"

"We can't use common sense to judge the relationship with Qinglianzi in the car, God knows what he thinks. Chu Xunyu sighed, put away his long sword, bandaged his palm, and secretly said that his ancestor always likes to make trouble for himself, and what he has done to harm the local people, and he can only go on hard.

The three of them went down the passage with torches, the passage was very narrow, and could only accommodate a half-less position, Chu Xunyu walked in the front, Mu Yuan was in the middle, after forgetting the dust, there was nothing else superfluous along the way, just a deep and dark road, Mu Yuan looked left and right, and asked a little lonely: "The place here is so deep, where can you go?" Don't dig too deep in the end, dig to the Nine Hidden Underground Mansion." ”

Chu Xunyu's brows are getting tighter and tighter, not because of Mu Yuan's alarmism, anyway, he is used to Mu Yuan's nonsense, but because the breath here is too dry, it stands to reason that there are at least a few hundred zhang deep in the underground now, don't say dry, even if there is an underground dark river, how can I not smell the smell of water and mildew at all? Unless it is that the "Three Ending Formations of the Turning Sun" is still in operation, but it has been hundreds of years, how can this formation still be maintained? Unless...... There are still people living in this bottomless underground......

Mu Yuan looked left and right, and became more and more curious, and found that the surface of the cave wall was smooth, as if it had been polished, and immediately approached and touched it with his fingertips, and asked: "What is this made of? Agate and jade? ”

After speaking, Mu Yuan looked at it carefully with great interest, and suddenly it was wrong, he opened his mouth and wiped it desperately with his cuffs, and his soul fell off at the moment, and he exclaimed: "My Amitabha Buddha blesses!"

Chu Xunyu hurriedly looked back, only to find that the other side of the cave wall was crawling with dense red-eyed spiders......
