Last time, it was said that Shen Yifan was breaking the army; Before the Wuqu Liangshan Pass, he first encountered a kind of grasshopper that could suck blood, and then encountered a rain of arrows, at this time he heard the voice of Jin Jiyu and the expert, although he tried to shout but everyone could not hear it, his voice was muffled by the sound of the rain of arrows.

Shen Yifan heard Ah Bing's cry of "Lao-Ban-" in the foggy arrow rain, and his heart sank, and he thought to himself: "The gold and jade will be fine, right?" At this time, there was a sudden murmur in his chest, and then he remembered that he had a walkie-talkie, and hurriedly picked up the walkie-talkie and shouted: "Gold inlaid jade; Gold inlaid with jade. ”

"Shen Yifan, is it Shen Yifan." There was a gold and jade voice on the other end of the intercom, and it was obvious that the voice was very excited.

Shen Yifan shouted: "Everyone is all hiding, don't come out." There are organs. ”

"Damn-Shen Yifan, you finally appeared!" At this time, the voice of an expert came over the intercom.

Shen Yifan didn't have time to take into account the expert's ridicule and asked, "Are you okay?" ”

Ah Bing said with a crying voice: "Gu Jie is dying. ”

When the expert heard the walkie-talkie, he scolded: "Damn." ”

Shen Yifan asked the reason and knew that Ah Bing's cry just now was not an accident with Jin Jiaoyu, but Gu Jie was in danger. Things have to start again from everyone jumping into the cliff, Gu Jie's posture was a little awkward when he jumped off the cliff into the river, and his stomach slapped directly on the water, and he was shocked with internal injuries, although he didn't know where the injury was, but he felt very serious, and he walked all the way here, just now Gu Jie spit out a few mouthfuls of blood, Ah Bing felt that Gu Jie was about to run out of oil and the lamp was dry.

After hearing this, Shen Yifan said, "You stay and don't move." Everyone heard the name of the walkie-talkie. ”

When the report came down, it was found that there was still a lack of prescription and motor, and the expert said on the walkie-talkie: "The two of them lost contact after jumping off the cliff, and they still don't know whether they are alive or dead." ”

When the words came this, Shen Yifan felt that the arrow rain outside began to fall sparsely, and after a while, the swishing sound slowly disappeared, and it was strange to say that when the arrow rain stopped, the thick fog slowly subsided, and soon the moonlight sprinkled white cold light, Shen Yifan looked around and found that there was no one around, only him, and the ruins were full of feather arrows.

Shen Yifan called several times on the walkie-talkie to ask about their respective locations, and then he heard Fang Zi say: "I'm with the motor in the east." ”

Jin Zhuyu said: "I am in the southeast and Ah Bing; Gujie together. Gujie is very dangerous right now. ”

The expert said: "I am with Sanniu, it should be in the northeast. ”

Shen Yifan looked at the compass and said, "I'm in the northwest direction, and I'm with Murong Wan'er." ”

As soon as everyone finished reporting the location, Shen Yifan saw three flares rising from Shen Yifan's opposite at the same time, illuminating his eyes, Shen Yifan found that there was a huge city between them and himself, and by the light of the flares, he could clearly see that the city was very close to Shen Yifan, probably only a dozen meters away in a straight line, and there seemed to be someone guarding the city wall, all holding bows and crossbows.

Shen Yifan had already guessed that Jin Zhuyu and the others would not be in the same direction as him, because Shen Yifan had already passed through the pass city when he came out of Yinglong Cave, so he would naturally become an opposite direction to Jin Zhuyu and the others, but he was surprised that he heard the voice just now as if everyone was around.

Jin Jianyu shouted over the intercom, "Where are you exactly?" Shen Yifan——! ”

Shen Yifan was still surprised that he didn't pay much attention to the words on the walkie-talkie, but Jin Jianyu screamed a few more times, and Shen Yifan realized that he was also going to shoot a flare to report the location, saying that a flare shot out and illuminated his neighborhood. This time it seems a little strange to see that I am in a ruined wall, this wall seems to be deliberately built outside the city, and it is already dilapidated after the wear and tear of time, but it can be seen that the wall here should be a straight line connecting the city. Shen Yifan guessed that it was a fortification outside the city pass.

The wall is divided into three lanes, the distance between the front and back is about three or four meters wide, and the length of each wall is about dozens of meters long, Shen Yifan's wall to avoid blood grasshoppers and arrow rain is a little strange, there is a gap about two meters long in the middle, and looking at the edge of the wall, it does not look like it is caused by damage, it seems that when it was built, it was intentional to leave a horizontal gap between the wall and the wall, looking at the wall in front of it, but the wall behind it is a complete wall, although it is a little dilapidated and broken, but it can be seen that it is a whole wall.

Shen Yifan was a little curious about the walls in front of him, why did the ancients make these walls so strange? Are these walls just for the purpose of defending the city? Shen Yifan suddenly thought of a question, he is now in the hinterland of the two mountains of Pojun and Wuqu, so he should be behind the pass, so why is he also attacked by the pass organs? Could it be that the mechanism of this pass will attack in all four directions? Is it an indiscriminate attack mechanism?

Shen Yifan was thinking about this question when he heard the gold inlaid jade in the walkie-talkie and asked, "Shen Yifan, why are you already behind?" ”

Shen Yifan said: "I will tell you in detail when we meet. Then he asked, "What's the situation on your side?" Don't blindly enter the gates ahead. ”

"We seem to have a lot of dilapidated houses in a village, and the situation is not very good, and Gujie has suffered serious internal injuries. ”

Shen Yifan said: "In front of you is an organ city set up by Qi Chungang. Before all ...... could utter the word 'so', they heard the walkie-talkie shouting, "Not good!" Not again. Shen Yifan was a little puzzled when he heard it, and he heard Jin Zhuyu shouting: "Hide." Hide! ”

Shen Yifan looked at the front and didn't seem to have anything happening, and couldn't hear any sound, so he hurriedly asked, "What's the situation?" What's the situation? ”

At this moment, I heard another cry in my ear: "Don't move." Don't move. This voice didn't come out of the walkie-talkie, but it felt like it was only a meter or two away from Shen Yifan, but the strange thing was that Jin Zhuyu and the others were still outside the pass, why did Shen Yifan feel like this.

At this time, Shen Yifan couldn't care about it so much, and hurriedly walked towards the city in front of him, he didn't think about walking a few steps, and the whole person was stunned, he saw a pair of people coming slowly from the same place, and the speed was very slow, slowly coming towards him along the main road. From a distance, it seemed that the group of centaurs was not coming but slowly drifting over, which looked particularly strange in the night. Looking at a team of people and horses, there were hundreds of people, but they came silently, and there was no sound of neighing horses' hooves.

This made Shen Yifan a little terrified, in the dark night, a team of nearly a hundred people actually came towards Shen Yifan silently and in a floating way, and when the team was closer to Shen Yifan more than 100 meters, he saw that it was actually an ancient army, all golden, looking at the four armored soldiers on horseback in front of him, followed by ox carts, looking like an ancient grain delivery team.

Shen Yifan was even more frightened when he saw this, could the pass in front of him still be guarded by ancient people, why was there still a team delivering food towards the pass, could it be the ghost of the soldiers guarding Beidou City? Soon Shen Yifan found that there was something wrong with this team, when the team was only forty or fifty meters away from Shen Yifan, the team still slowly walked towards this pass and completely ignored Shen Yifan, at this time Shen Yifan saw that the so-called food delivery team was actually a wooden puppet and an ox cart, and when he saw this, he put down his heart hanging in his throat.

In fact, what Shen Yifan saw was a very mysterious technology in ancient times, a bit like a kind of wooden ox and flowing horse during the Three Kingdoms period. What Shen Yifan saw in front of him was even simpler, there was a very hidden track on the road into the pass, and the team he saw was actually a puppet and a wooden ox pushed into the pass along the track.

When this wooden ox and horse came to Shen Yifan's side, he clearly saw that the ox cart had slowed down the feather arrows, and the dozen or so ox carts were full of feather arrows.

Shen Yifan immediately realized one thing, the mechanism in the pass may mainly rely on feather arrows for defense, just after a burst of fire, maybe the feather arrows in the pass mechanism are gone, it touched a certain mechanism to start the wooden ox and the horse to transport the feather arrows to load the mechanism with feather arrows, if the track of the feather arrows is destroyed, it should be able to let the pass let Jin Zhuyu and others pass safely through the pass in front of them. Thinking of this, he pulled out a long knife in his hand and looked for a track along the front of the wooden ox and flowing horse, but then he found that this idea was too naïve, he could think of this trick, and the ancients could naturally think of this trick, so the track was buried deep in the ground, and there was no way to destroy the track without huge excavation equipment, it looked like a knife to cut those wooden oxen and horses, but a knife went down to shake the tiger's mouth and hurt that the wooden ox and the horse actually did not even have a trace, and then looked at it and found that these were made of iron and wood and could not be destroyed at all.

Only then did Shen Yifan know why these wooden oxen and horses were golden, but in fact, they were not golden, but iron and wood. Ironwood is a kind of tree that grows in the shade, it is one of the very rare woods, there is no growth environment for this kind of tree on the ground, so generally this kind of tree grows underground, generally in the karst cave or in the construction of huge rock formations underground, because there is no sunlight all year round, so the growth rate is very slow, the general tree increases a circle of annual rings a year, and this is a ten-year increase of a circle of annual rings, a tree that can be grown into ironwood is basically more than 500 years, And there is no photosynthesis, so basically one or two of a thousand trees will survive, and the others will wither and rot. As the name suggests, its wood is as hard as iron, plus rare, so this kind of wood can be said to be generally used in the construction of the mausoleum of the royal family in the past dynasties, it is rumored that the Qianlong Emperor of the Qing Dynasty wanted to find an iron wood as the main beam of his mausoleum was also unsuccessful, and later used a golden silk nanmu instead. Because ironwood is as hard as iron, this wood is generally used to make the main beams of buildings, and is rarely made into utensils, because there is no technology to break ironwood. And the wooden oxen and flowing horses in front of Shen Yifan are actually all made of iron and wood, which makes Shen Yifan unbelievable, what method did the ancients of Beidou City use to disconnect and manufacture these iron and wood and do it so vividly?

When Shen Yifan thought of this, he heard a noisy sound coming from the walkie-talkie, and when he heard it carefully, it turned out that Jin Zhuyu and the others looked at the pass in front of them and did not reflect for a long time, and felt that the danger had passed, so they walked towards the pass.

Unexpectedly, when they came to the front of the pass, they found that the gate of the pass was open, and everyone entered the pass without thinking, and as a result, they entered the trap of ancient Qi Chungang. Jin Zhuyu and others entered not the real pass city but the urn city in front of the pass city, when they entered the pass from all directions, all the gates of the pass were open, and when everyone entered, those city gates were slammed shut, Jin Zhuyu and a few others stood on the empty school field, you look at me, I look at you, you don't know what happened.

In ancient times, the city walls had an urn city, and this urn city was specially used to besiege the enemy's army.

Jin Zhuyu and the others looked at the four high walls and began to mumble in their hearts, and they could hear the sound of hidden buttons in the surrounding walls, and the sound of gears and chains gushing endlessly, and everyone secretly screamed in their hearts. Just when everyone knew that they had fallen into the trap of the ancients, they saw countless puppets appear on the city wall, and then feathered arrows were shot at them.

Jin Zhuyu and the others were also agile, and when they saw the feather arrows shooting from the wall, everyone quickly gathered together, and everyone actually put their backpacks together and retreated all the way to the corner of the wall, and used their backpacks to form a shield to cover the feather arrows.

The backpacks of the gold and jade expedition team are basically tactical backpacks, this kind of backpack has an advantage that in order to cater to the shape of the human body, there is a high-plastic plate in the back, the toughness of this plate is very good, it can resist ordinary feather arrows, everyone will put all the backpacks together, and everyone retreats to the dead corner, so that it is one side of the attack of feather arrows, and it is safe for the time being.

When Shen Yifan heard this, he knew that they couldn't last long if they used their backpacks as shields, and if they didn't hurry up and find a way to get them out of danger, it was estimated that they would all become hedgehogs soon. Thinking of this, a plan came to his heart, since he couldn't do anything on the wooden ox flowing horse that transported the feather arrows, he could only look for any flaws in this pass. Seeing that the city gate was slowly opening on the route of the wooden ox and flowing horse, he knew that it was an excellent opportunity to enter the pass, and he made a 100-meter sprint towards the city gate.

As soon as Shen Yifan entered the pass, he was stunned by the hidden buckle of the mechanism in the city wall, the entire pass city wall is a set of extremely complex automatic mechanisms, all of which are composed of geared iron chains, like an assembly line for transporting feather arrows, looking at the wooden oxen and horses, as soon as they entered the pass wall, those ox carts entered a huge wooden box, and looked inside, the box was full of feather arrows, and these feather arrows were like the bullet chain of machine guns, constantly delivering feather arrows to both sides.

It turns out that this so-called pass is a huge mechanism, and the pass divides the urn city; The main city and the organ city are composed of three parts, Jin inlaid jade and others enter the urn city in front of the pass, the main city is also a set of very sophisticated organs, we will not care about the rules again, the organ city is the core part of the entire pass mechanism, so the entire pass is finally behind the organ city.

The main mechanisms in the city are in the wall, almost every space in the wall is gears and chains, dozens of meters high in the internal wall can see a very complex chain and gear composed of a series of machines, and the main function of this machine is to transport feather arrows for the main city.

As soon as Shen Yifan entered the organ city, he was stunned by these complex machines, he could hardly believe that the mechanism machine in front of him was from the hands of the ancient Tang Dynasty, even if modern people were asked to draw a gourd according to this set of organs, it may not be possible to build it. The machine in front of me can send feather arrows to the main city without deviation, and you can see that the feather arrows are sent out of several huge wooden boxes, and those wooden oxen and horses can be accurately loaded into those wooden boxes without deviation, and then rely on the gears of different sizes in the wooden boxes to deliver these feather arrows into one by one.

Shen Yifan looked up at the wall, the inner wall of the organ city was very high, estimated to be about forty meters high, along the iron chain tracks above Shen Yifan's head, you could clearly see that those feather arrows were sent to the huge wooden box of the organ city in all directions. There was a sonorous sound of metal rubbing above his head, each sound meant that Jin Jianyu and the others were in danger for one more minute, but this set of mechanisms was right in front of Shen Yifan's eyes, and what could be done to stop this huge machine?

Shen Yifan looked around at the fact that there was nothing to make this machine stop, and the strangest thing was that this machine was like a huge perpetual motion machine, which seemed to be an inexhaustible source of energy once the mechanism was activated. If we can find a place to supply the power supply for this machine, destroying it should stop all the machines in the entire machine city.
