Yang Feng didn't ask Zhang Daofeng how the five steps were calculated, he felt that since Zhang Daofeng dared to say so, then there was a certain particularity here, staring at this mountain wall, Zhang Daofeng was also surprisingly silent, it should be thinking of a way to crack, the law that is inseparable from its sect seems to be not very applicable to the technique, each has its own usefulness, each has its own subtlety.

Looking at the mud sticking to the mountain wall, Yang Feng suddenly thought of a possibility and asked, "Did you say that it was a long time and then the mechanism was glued?"

"There's a possibility, you can clean it up and take a closer look. Zhang Daofeng said hurriedly.

Yang Feng smiled bitterly and said, "Brother, no, uncle, how long do you think it will take for me to clean up this large piece as clean as my toes?"

"Stupid! just let Bai Jiao come out and spray it with water, that guy is equivalent to a high-pressure & water gun. Zhang Daofeng came up with an excellent idea, so that Yang Feng couldn't help but be stunned, but I don't know if Bai Jiao will trouble him, a good millennium Jiao will become a high-pressure & water gun.

Bai Jiao's water gun can sink the boat, Yang Feng didn't dare to let it use all his strength as soon as it came out, but told it to take it easy, just wash the dirt on the mountain wall, after paying a few jars of wine, Bai Jiao was full of energy, and quickly cleaned up the mountain wall, very clean.

"What now?" Yang Feng glanced at it, nothing special, and asked Zhang Daofeng.

"Do you think that those seven stones are a bit like the Big Dipper?" asked Zhang Daofeng.

Yang Feng took a closer look, trying to find the Big Dipper, and he really found it, the more he looked at it, the more it looked like it, it was seven raised stones, although it was not very obvious, but it was a Big Dipper in a line.

"Head or tail?" Finding the location of the mechanism, Yang Feng asked anxiously.

"I don't know. "At this point, Zhang Daofeng is not sure, let alone the head and tail, it is possible for any of them, God knows what kind of thinking the guy who built this, the more amazing the talent, the more you can't reason with common sense.

"Whoosh!" Yang Feng tried to press the moment on his head, if he was placed in the Seven Stars, it should be the North Star, after pressing it, more than a dozen thorns suddenly shot out from the stone wall, Yang Feng dodged into the Nine Creeks Spirit Domain, he has been careful, otherwise he would have to let his daughter fly over to heal him if he didn't die.

"There's a mechanism on top of this thing. Yang Feng's eyes widened, staring at the place where the arrow had just been shot, if it wasn't for the place where the arrow was really shot and almost killed him, how could he have imagined that those few small holes actually had such a killing move.

"The wisdom of the ancients is not something that modern people can understand, you have to be careful and careful, don't warp. Zhang Daofeng reminded.

"Brother's existence is to shake the ancient and modern Chinese and foreign, you just look at it. Yang Feng pressed the next star again, and as soon as he pressed it, Yang Feng entered the Jiuxi Spirit Domain, and did not give the ancients who had been ancient to react, this time the situation was very unexpected, it was not an arrow, but a pit, and a pit suddenly opened under his feet, and inside the pit was an iron thorn that exuded a cold glow, and I don't know how many years have passed, but there is no rust at all, which shows the subtlety of the design of the mechanism.

"Khan!" Yang Feng wiped his sweat, threw a wooden board out, stood on top of the pit, pressed one for interest, and flashed when he pressed it, this became a habit, but nothing happened, Yang Feng was stunned, and suddenly smiled, this stone, it seems that it was not pressed, went out and studied it again, it is indeed not pressed, this piece is dead, but then Yang Feng did not dare to be careless, whether it is alive or dead, as long as you press it and run, but unfortunately the next three pieces, all of them are dead, they are genuine stones, there is no mechanism, there is no trap, the last one, the answer is also on this one, Yang Feng feels that his luck is really not good, the probability of choosing one hundred and fifty percent of the two, he actually chose the wrong one。

"Poof!" Yang Feng just pressed down, a piece of the stone wall suddenly collapsed, spewing out a puff of purple smoke, Yang Feng entered the Jiuxi Spirit Domain again, and looked at the situation outside with the eyes of heaven with palpitations, this ancient master didn't know who it was, but no matter who it was, Yang Feng had to curse him for giving birth to a son without a fart, this is too poisonous, none of them are open door organs, not to mention, each of these things can kill people.

released a big eagle, let it fan its wings, and fan the unknown poisonous smoke that did not know the effect to the side, Yang Feng let Bai Jiao go out and purify it with water, and waited for a while, then he dared to go out, was shot by an arrow, was cut by a knife, at most it was to open a hole, open an opening, but this poisonous smoke is different, this thing inhale it, and if it is not good, it will be killed.

"Master, this is definitely a master, there must be something amazing hidden here. Zhang Daofeng shouted excitedly, the more vicious and subtle the mechanism, the more it can prove the preciousness inside, and he wishes he could have it again.

"Don't worry about getting excited, how should this door be opened?" Yang Feng asked angrily, this is definitely not hiding a backache, but he is in danger of life and death outside!

"According to the general law, one of the ones that can't be pressed in front of you should be able to press. Zhang Daofeng said.

"Are you sure?" asked Yang Feng suspiciously.

"Sure!" Zhang Daofeng nodded affirmatively.

Yang Feng pressed the four stones that could not be pressed one by one, when he pressed the middle piece, no matter how many people counted from there, it was the fourth piece, he heard a sound of pricking, and the stone wall slowly opened a door more than two meters wide, and the door height was also about two meters, Yang Feng hid to the side, waiting for the fresh air to enter inside, and the eye of the sky had already looked into it, it was very complicated inside, just like an underground factory.

"Zaza!" didn't give Yang Feng much time, only about three minutes later, the stone door automatically closed, Yang Feng ran in quickly, and after entering the door, he entered the Jiuxi Spirit Domain, he didn't dare to breathe the air inside, God knows if it was poisonous, although his physical fitness was far beyond ordinary people, but it had not yet reached the point where it was inviolable.

Yang Feng released a few rabbits, waited for almost half an hour, the rabbits had nothing to do, they were jumping around in it, Yang Feng went out from the Nine Creeks Spirit Domain, and released a few owls, letting the owls open the way in front, and he walked slowly behind, and the eye of heaven extended forward, checking the situation inside.

A few dry skeletons, the clothes on them are a bit like the soldier uniforms of a certain dynasty in ancient times, Yang Feng touched it lightly with his hand, and the place where he touched it was like ashes, Yang Feng was stunned and understood, this is too long and has been eroded, according to the relatively fresh air here, this hole is not a dead hole, there are vents and other places.

In the cave, there are many such soldiers, according to the costumes Yang Feng found, there are soldiers and officials, but these officials look at the costumes are generals, this place is like an underground factory, it is a factory, and it is also an arsenal, in addition to bows and arrows, Yang Feng saw several ballistas, each crossbow arrow is more than two meters long, there is an arm thick, no matter where it is shot, it is estimated that it is a hole, that is, a rock, can also shoot through.

The ballista and catapult are all rusty, I'm afraid that the people who built here, or the people in charge of this place, didn't expect that these things would go through such a long time before they would see the light of day again, opened a few boxes, and found a few repeaters inside, wrapped in oiled paper, like new, Yang Feng didn't have time to watch, and hurriedly collected them in the Jiuxi Spirit Domain.

Yang Feng is not an expert in archaeology, and he can't analyze the specific age of these officers and soldiers through clothes and accessories, looking at clothes and weapons and other things, it should be the Western Han Dynasty, but this section of the Great Wall, wasn't it built in the Ming Dynasty, how could there be an arsenal of the Western Han Dynasty under the Great Wall, is this a coincidence or not? This is not something that Yang Feng can figure out, this matter needs professional understanding to analyze and verify, he is afraid that he does not have the patience and idle time.

Ballista, moved, catapult, moved, all kinds of weapons, all a few pieces, as for the gold, silver, jewelry, jade, etc. in a stone room, Yang Feng naturally will not continue to stay here, there are no peerless cheats, no Taoist classics, and no historical secrets, all these may have, but they have all disappeared in the long river of history, although there are no these, but if such a place is present, it will still cause a sensation in the world.

Yang Feng really wanted to call the Cultural Relics Bureau directly and ask them to receive it, but it is estimated that in this way, he will definitely be convicted of destroying cultural relics, even if there is no one else who can't even open the stone door, but many important things in it have disappeared, this has to be counted on his head, a reason, if you don't open the stone door, these things will not disappear, you have no reason to talk about this matter, what are you talking about, people may tell you that we don't have technology now, but after decades, hundreds of years, we must have mastered some technology, and can preserve these things completely, then it is the same kind of thing as "open sesame".

Even if Yang Feng opened the door and the things inside were destroyed, there was no dime to do so, as long as he opened the door, this account would still be counted on his head, so in order not to become a sinner through the ages, he planned to find a suitable time, and then publish this thing, before he found this suitable time, this place, let him continue to sleep, anyway, he has been sleeping for many years, he doesn't care about more, except for a bunch of broken copper and iron, everything else has been moved by Yang Feng, Yang Feng is not afraid of being damaged, if it must be lost in the long river of history, at least there are some things in his Jiuxi Spiritual Domain, which can prove the existence of these people and this incident。

There is nothing in the stone cave, but Yang Feng is very interested in these natural vents, these vents, to put it simply, are the cracks in the rock wall, and I don't know if the master chose such a low, the underground factory built is so exquisite, according to Yang Feng's calculations, these vents in the factory, not to mention the iron casting weapons in the factory, even if the bomb explodes, the sound will not come out, the sound is completely blocked and transmitted in a roundabout way, and can only be heard inside.

Noticed these vents, on the one hand, because he was very curious about this, on the other hand, Yang Feng saw medicinal herbs in the cracks of these rock walls, and there were a lot, there were thousands of years of ginseng, thousands of years of He Shou Wu, Yang Feng has always believed that this kind of thing is extinct in the real world, but now it seems that in some wonderful places, there are still left, for these things, Yang Feng is naturally not polite, all transplanted into the Jiuxi Spirit Domain, otherwise when this underground factory is discovered, then these things will also be dug up, after all, as soon as you get close to here, the fragrance in the air will definitely be noticed。
