It turns out that the top of the ventricle is extremely high, and in the hunting firelight, I saw that the dome of the ventricle was at least ten zhang high, equivalent to thirty meters in later generations, and the diameter around it was three zhang, which was an extremely tall and wide stone chamber.

Li Zhen lit the three grease mortars around him, and the flames lit up, illuminating the ventricles as if they were day, and this magnificent ventricle was clearly displayed in front of them.

The ventricles are actually like an inverted bell, all made of granite, and the stone walls are very smooth, and there is not a single gap in sight, but the ventilation is very good, and there is no feeling of stuffiness.

In the middle is a round stone pillar, which requires two people to wrap around, and the stone pillar stretches straight to the dome, and the stone pillar climbs and winds upward, with nine dragon heads at the top, as if to break through the top.

And the stone wall around slightly arched, and then look closely, the arch is covered with scales, it turned out to be the dragon body of nine stone carvings, according to the distribution of the nine palaces, the Qiangong, the Kan Palace, the Gen Palace, the Zhen Palace, the Middle Palace, the Xun Palace, the Ligong, the Kun Palace, the Dui Palace, each direction has a stone dragon, has been extended to the top.

The nine dragons in the dome gathered, and nine bronze dragon heads appeared, close together, and the dragon's mouth opened, just aimed at the nine dragon heads on the stone pillar.

"Brother Li, the entrance to the dungeon is here!"

Di Yan found the entrance to the ground, which was two huge bluestones, which were put together like a Taiji diagram, blue and white, which was particularly conspicuous, which made Li Zhen a little strange, since it was originally a dungeon dedicated to the Buddha's treasure, why was the entrance a Taoist Taiji pattern?

The two bluestones at the entrance of the dungeon are tightly knit and need to be opened with nine keys, and the nine keyholes are on the stone pillar in the middle, which must be opened one by one in order, but unfortunately one key is missing, so that this dungeon has to be abandoned.

However, according to Xie Daogu, the hub that opened the underground palace was still rotating extremely slowly, but they couldn't feel it.

Every seven years, the entrance to the underground palace will automatically open, and at the same time, a copper ball will fall from the mouth of each of the nine dragon heads at the top, which will fall into the mouth of the nine dragon heads on the stone pillar at the lower end, and after the nine copper balls fall, the entrance stone door will be closed again.

Here's the problem, the dungeon is old and not so precise anymore, and the time for the nine copper balls to fall is extremely short, and even if you have long wings, you won't have time to take out the items enshrined inside.

The only solution is to intercept the nine copper balls very accurately, so that the time can be extended a little, and as long as you are agile, you can completely take out the things in the dungeon.

Xie Daogu told him that the reason why he failed in the past was that he could not intercept the copper ball above, and the stone gate closed too quickly.

At this time, Li Zhen suddenly intercepted the nine copper balls, which was not as difficult as Xie Daogu said, as long as a high shelf was built in advance and the stone pillar at the top was covered with a piece of cloth, the copper balls would not fall into the dragon's mouth on the stone pillar.

For Xie Daogu, this is simply a breeze, and if she finds someone who is agile, she can also take out the things in the underground palace.

Then why did it say that it failed in the past because it was impossible to intercept the copper ball? And since the dungeon was opened every seven years, why didn't you take out the jade Linglong with the seal before?

This made Li Zhen's heart feel a little bad, and he faintly felt that Xie Daogu was not telling him the truth.

"Brother Li, the time is coming!" Di Yan whispered to Li Zhen, who was looking up and contemplating.

"Ah Yan, I don't think something is right!"

Di Yan pondered for a moment and said, "Brother Li, didn't you think that if we didn't do it, I'm afraid your eldest sister would be unsafe." ”

Li Zhen also thought of it, a ruthless person like Xie Daogu said it nicely, but where would they be given a choice, Xie Daogu had already threatened to exit yesterday, if she didn't do it, I was afraid that her eldest sister would really be in danger.

And from the name Wu Yinghong, he has already guessed a few points, I am afraid that this behind-the-scenes person is related to the Wu family.

Li Zhen nodded silently, now, he has no time to think about it, he took the shadow bow from his back, this is his method, shoot the copper ball with an arrow, the arrow has been filed by him, it is no longer sharp, and it can increase the contact surface with the copper ball.

Although Li Zhen's archery skills are superb, it is still not so easy to shoot out nine copper balls ten zhang away in less than half a pillar of incense, which requires absolute calmness and the ability to seize opportunities.

And Di Yan took out a roll of thin rope, and there was a plum blossom hook at one end of the thin rope, and she was responsible for going down to the underground palace to retrieve things.

There was also an iron rod and an iron hammer next to them, this was their emergency measure, if the time was too late, Li Zhen would first use the iron rod to jam the stone slab of the underground palace, and then use the iron hammer to smash the stone slab little by little.

Maybe no one had ever dared to destroy the dungeon, but he didn't care.

"Brother Li, it's about to start!"

Li Zhen had also heard the sound of 'click!' from the inside of his heart, and he opened his bow and arrow, pulled his bow like a full moon, and aimed it at the dragon head in the direction of the Qiangong.

At this time, the entrance of the underground palace slowly opened, and a cold wind blew out, without any peculiar smell, as Xie Daogu said, there are ingenious vents in the underground palace, so you don't have to worry about any filth.

"Brother Li, I'm going down!"

Di Yan rushed down the stone ladder with a torch in his hand, and at the same time as Di Yan went down, a round ball slowly appeared on the dragon head in the direction of the Qiangong, and almost as soon as the ball showed a little head, Li Zhen's arrow came out of the string and shot towards the copper ball like lightning.

The two dragon heads are only three feet apart, and the distance from which the copper ball falls is extremely short, which requires Li Zhen to seize the opportunity extremely accurately, and he will fail sooner or later.

At the moment when the copper ball just fell off the mouth of the dragon's head, the long arrow fired, and with a crisp sound of 'dang!', the copper ball was shot out.

The copper ball landed with a piercing crashing sound, but Li Zhen was almost unaffected, he had already drawn his second arrow, and drew his bow to aim at the dragon head of the Kan Palace

Di Yan ran down the underground palace with a torch, there was an oil lamp on the alcove, which was filled with lamp oil, Di Yan lit three lamps in a row, and the faint light filled the entire underground palace.

The underground palace is actually not big, the structure is like a blooming lotus, the middle is the lotus canopy, there are nine Yongdao around, like nine petals, corresponding to the direction of the nine palaces of the dome above, the end of the Yongdao is the jade platform where the items are placed, and there are only two Yongdao jade exquisitely in the present.

Di Yan carefully studied the mechanism map of the underground palace last night, there is no mechanism in the center of the underground palace, the mechanism is hidden in the corridor, and the two sides are full of shooting holes, as long as you step into the corridor, there will be crossbow arrows on both sides, and it is not all shot at once.

If you use the key to open the door of the dungeon, the hidden weapon mechanism will automatically close, otherwise even if you smash the stone slab and enter the dungeon, you will still be unable to escape the shooting of the poisonous arrows of the trap.

Xie Daogu also clearly told them that if they wanted to avoid the poisonous arrows, there was only one way, crawl through the air, and their feet could not touch the ground, Di Yan thought about it all night, and she felt that there was only this way.

Li Zhen's skills are absolutely not good, and only she can do it, Di Yan did not hesitate, she went straight to the Qiangong Yongdao, the Yongdao is about three zhang long, and the repair is very smooth, on the jade platform at the end of the Yongdao, there is a vaguely placed item about half a foot long, which is wrapped with golden satin.

Di Yan's eyes fell on the Buddha shrine at the top of the jade platform, there was originally a white jade Bodhisattva inside, but the jade Bodhisattva had been taken away, the Buddha shrine was empty, and there was a stone ridge on the edge, this was how Xie Daogu told her.

There was no time for Di Yan to distinguish carefully, she almost did not hesitate to throw out the plum blossom hook, the plum blossom hook accurately fell into the Buddhist shrine, she pulled hard, and the plum blossom hook hooked the stone ridge on the edge of the Buddhist shrine.

Di Yanxun tied the other end of the rope to the stone pillar outside, she pulled it hard, gently jumped up, climbed the rope in the air, and quickly crawled into the corridor.

Her agility was on full display at this moment, and in just a moment, she crawled to the end of the corridor, reached out and scooped up the jade Linglong, and put it in her backpack.

But at this moment, Li Zhen's anxious shout came from the entrance, "Hurry! Come out, the stone gate is starting to close!"

Di Yan was startled, and she couldn't care about the other jade Linglong, and desperately climbed the rope to crawl outside.

It turned out that Li Zhen had just finished shooting the nine copper balls, and the stone door at the entrance began to close, and there was no sign of delay at all.

What made him even more frightened was that the bluestone door was at least a foot thick, and it was polished extremely smooth.

He was in a hurry, and while shouting for Di Yan to come out, he picked up the iron rod and pressed against the stone gate, but the stone gate closed and weighed more than 10,000 catties, and the iron rod was immediately bent, and it fell into the underground palace with a bang.

The stone gate slowly closed, and Li Zhen was so anxious that he was going crazy, seeing that the stone gate was only two feet wide, and if he didn't come out, it would be over.

A rush of blood rushed to Li Zhen's brain, he actually had an urge to die with Di Yan, and just as he was about to jump into the dungeon, a figure rushed out of the dungeon.

Li Zhen could no longer suppress the excitement in his heart, and rushed up to hug Di Yan tightly, at this moment of life and death, he realized how important she was in his heart.

The stone door slammed shut, and after a long while, Di Yan gently pushed him away, only to see her smile on her face.

At the moment when she rushed out, she had already seen that Li Zhen wanted to jump into the underground palace, of course she understood what that meant, which made her heart also very moved, she suddenly stopped hating that female Taoist priest, and even a little inexplicably grateful to her.

The girl's reserve made Di Yan restrain the emotions in her heart, and she smiled and said, "Why are you so unconfident in me?"

Li Zhen only felt that his legs were weak, and he was still afraid for a while, so he simply sat down, and only after a while did he say in annoyance: "I think we are all crazy, is it necessary to take this risk?"

Di Yan squatted down beside him and comforted him softly, "Because we didn't expect it to be so dangerous, it's too late to wait for now, and Brother Li doesn't have to blame himself, after all, we are not gods, not everything can be expected, eat a trench, grow wise!"

Li Zhen sighed and said: "But I almost lost my life, this price is too great, I am too stupid." ”

"I think it's worth it, you see, I'm not jumping in front of you right now?"

Di Yan took off the skin, and said with a little regret: "It's a pity that the time is too late, I only got a jade Linglong, I don't know if it is a breach of contract?"

As soon as Di Yan's words fell, a woman's voice came from the entrance of the ventricle, "It's already very good to be able to get a jade Linglong, seven years ago, even your master almost died in it." ”

The two hurriedly turned around, only to see the female Taoist aunt Xie Ying slowly walking in, followed by Wu Yinghong and more than a dozen subordinates.

Li Zhen and Di Yan stood up, Li Zhen glared at her angrily, but Xie Ying smiled faintly: "I have already sued you before, things are not easy, isn't it?"

Li Zhen said hatefully: "But I shot nine bronze balls, but I didn't delay the time at all, what do you say?"

"Do you think it won't work? I can tell you that if you don't intercept the copper ball, the stone gate will not open at all, and when the fifth copper ball falls, the stone gate will begin to close.

Seven years ago, we didn't intercept the copper ball, and Aunt Gongsun almost died in it, although she also rushed out at the last moment, but she didn't get a jade Linglong. ”

Speaking of this, Xie Ying sighed again, "We will not intercept the copper ball unless we have to, because once the copper ball is intercepted, the dungeon will never be automatically opened again, and we dare not take this risk." ”

Only then did Li Zhen know that the automatic opening system of the original underground palace had been destroyed by him, and he looked back at the tightly closed stone door, so he could no longer take out another jade Linglong.

At this time, Xie Ying stretched out his hand, "Give me Yu Linglong!"

Li Zhen hesitated for a moment, he didn't want to hand over Yu Linglong so quickly, just as he had just shown a hesitant expression, Wu Yinghong and more than a dozen of his subordinates raised their crossbows together and aimed them at the two of them.

Di Yan knew very well in her heart that they had no choice, she took out the jade Linglong without hesitation and handed it to Xie Daogu, "Since we have taken out the jade Linglong, it is time for you to fulfill your promise." ”

Xie Ying took Yu Linglong and glanced at Li Zhen deeply, "My master is already waiting for Li Gongzi in the Yuexia Villa, he will tell Li Gongzi what he wants to know, please!"
