Last time, it was said that Jin Zhuyu and others strayed into the pass urn city and were trapped in the rain of arrows and were in danger, Shen Yifan entered from the back of the pass and found a set of extremely complex mechanism machines in the organ city, he decided to find a place to provide energy for these machines, and destroy it so that the mechanism of the entire pass could be disabled, but what did such a large machine rely on to provide inexhaustible energy?

Shen Yifan's first thought was steam, such a machine with a combination of huge gears and iron chains, in addition to steam, he really couldn't imagine that there were those energy sources that could start such a huge machine, but if it was steam, the temperature would rise in this confined space, but the temperature here didn't look very hot, so he quickly ruled out the idea of vapor power, so what other way could drive these machines? There's also the question of how exactly they triggered the activation of the Pass Mechanism?

Shen Yifan took advantage of the gears and chains of those machines to vertical several layers, looking at these precision machine parts, he was also impressed by the wisdom of the ancients, those large and large gears are the size of a grinding disc, and the small ones are only the same as a penny coin, each gear performs its own duties, constantly rotating to drive the iron chain and the track carrying feather arrows, at this time Shen Yifan has gone up to twenty meters, at this time, a huge air flow crossed his head, looking up, everything has been understood, these huge poles are driven by the wind.

It turned out that there were several rows of half-meter-long and wide square holes on the wall close to thirty meters in the organ city, and a huge wind force was blown in from these holes, and the corresponding machine of the holes was our common windmill, those hurricanes blew the windmill like a propeller and kept rotating, driving all the gears and chains below, and above the windmill were rows of neat tracks that could hear the sound of feather arrows being transported. But soon, another problem was placed in front of Shen Yifan, the windmills above his head were actually made of very thin bronze sheets, coupled with the huge wind power, the speed of those windmills was almost impossible to see with the naked eye, unless such a force was a thick iron rod that stuck all the windmills at the same time, otherwise it would be in vain. Moreover, the speed of the windmill is enough to stir Shen Yifan into meat puree, and the hurricane will crush the bones and scatter ashes.

Just when Shen Yifan was still hesitating, he heard a huge sound of rolling logs, and looked at the sound, a thick log was slowly being driven up by the track into an entrance below Shen Yifan, and then an endless stream of logs was sent up from below, and then entered from different entrances.

Shen Yifan would not miss any opportunity, and immediately followed those logs to the entrance of the logs, and looked inside, this is actually a circular tunnel, of course, this tunnel is not for people to walk, but a tunnel for transporting logs, the width and height can accommodate one person to crawl in.

Shen Yifan climbed into the tunnel without thinking, and along with the circular tunnel, he saw that both sides were crawler hooks to fix the accessories for transporting the logs, and he could soon see a circular tunnel that went straight up and down with the tunnel, Shen Yifan was still hesitating whether it was up or down, and he felt a strong wind coming behind him, and then a huge force brought him directly to the tunnel that went straight up and down, and fell directly down.

Shen Yifan complained bitterly in his heart: "It's not good! This time, I'm going to take a break. Before he could finish thinking about it, the whole person fell heavily on a row of tracks and flew forward.

Shen Yifan felt that at this time, he was like a pig on the assembly line on the slaughterhouse, waiting for slaughter on the assembly line, and soon he was taken to the front of a machine by the track, and after watching the log in front of him being put into the machine, he heard a loud noise shot out like a cannonball, and he understood that this was a kind of rolling wood for defending the city. He didn't want to be ejected by the machine in front of him, and by the time he was about to get into the catapult machine, a man who had turned over had already jumped off the track, like a bat, clinging to the rock wall of the tunnel and slowly heading towards the wide place.

When Shen Yifan came to the open place, he took a closer look, and it turned out that the principle of the catapult machine was very simple, that is, like a huge slingshot, it would be ejected directly after the log was loaded, and then it returned to the winding again and waited for the next log to be loaded.

There is a gap more than one meter wide in front of the machine, and all the situations in the urn city can be seen from the inside, Shen Yifan then looked at the gap at this time, the school field in the urn city was already full of feather arrows, and at the same time, the rolling logs were ejecting away, fortunately, the place where Jin Jiyu and the others were hiding was a dead end, and the logs could not be hit for the time being. But as the logs shot farther and farther away, sooner or later, the backpacks and shields of Jin Jianyu and others would be crushed by these logs.

Shen Yifan was anxious, but there was no way to stop this huge machine, at this moment, from the gap, he saw that there seemed to be a huge dark cloud flying above the pass, the speed was amazing, and if you took a closer look, it was actually the blood grasshoppers that she had encountered before, those grasshoppers pounced towards the pass, and soon you could see a lot of grasshoppers pouring into all the gaps, Shen Yifan sideways avoided the whole person, shrank in the corner, blocked the front with his backpack, and heard the grasshoppers hitting those machines, Soon the machine stopped as if it had failed, and only the sound of countless winding could be heard, and I don't know what was going on inside the pass.

This process lasted for about fifteen minutes, and after Shen Yifan could hear the sound of a huge bowstring bounce, and then he saw countless arrows shooting straight ahead from above the pass at the same time, chasing the grasshoppers. This time, the feathered arrows happened very neatly, and they went in all four directions at the same time.

Only then did Shen Yifan understand that the feather arrow attack he encountered at the beginning was not aimed at him, but towards those grasshoppers, why there was such a thing, Shen Yifan couldn't explain it for a while, but just like this, Shen Yifan had a chance, Shen Yifan seized this golden opportunity, and used the Yiwang knife in his hand to chop a catapult machine that launched a log in front of him, and then blocked the entrance of the tunnel with a log.

At this time, those blood grasshoppers swarmed in with the gap in the city wall, and quickly disappeared from Shen Yifan's sight, and then he could hear the sound of a neat bowstring winding, and then he heard the sound of feathered arrows swishing in all directions. At that time, Shen Yifan didn't know why these feather arrows were fired, but later he understood that maybe those blood grasshoppers flew to touch a certain mechanism, causing all the feather arrows to shoot indiscriminately in all directions, and this mechanism might be a mechanism with a group defense function.

After the sound of feather arrows became scarce, the sound of gear chains could be heard, and this time the sound of the tunnel transporting logs in front of Shen Yifan began to be abnormal, and the sound of the tracks inside being stuck and not moving forward could be heard, and soon the sound of machinery inside was heard and many parts were broken to the ground, and then all the gear tracks around Shen Yifan stopped working, and from the gap, you could see that the crossbow and arrow mechanisms on the main city had also stopped attacking. It is very likely that after the mechanism of the organ city had a problem, the mechanism of the main city also had a problem, causing the mechanism of the entire pass to stop functioning.

This is indeed a once-in-a-lifetime opportunity, Shen Yifan immediately continued to climb towards the top of the organ city, crawling out from a gap that launched a log, and then jumping with his light skills, the whole person was like a strange bird, spreading his arms in the air, gliding towards the main city, and inserting the Yiwang knife directly into the wall of the main city, all the way towards the head of the main city wall. On the wall of the main city, I saw rows of puppet soldiers holding bows and arrows aimed at the urn city, and the feather arrows were wound but not fired, because the mechanism of the city was stuck by a large log, so all the mechanisms in front of me stopped working.

Shen Yifan could see the gold inlaid jade and others in the urn city in front of him from the wall, and hurriedly shouted on the walkie-talkie: "The golden inlaid jade is coming towards the main city." As he spoke, he untied the flying tiger claw on his waist and threw it towards the city wall, and Jin Zhuyu and the others ran towards the thrown flying tiger claw rope at a speed of 100 meters.

Just when Jin Zhuyu and others were about to approach the rope, a row of square holes appeared on the wall of the urn city, and then a row of feather arrows shot out, this time it was not an ordinary feather arrow but a feather arrow with fire, these feather arrows were shot directly on the school field of the urn city, and a wall of fire more than one meter high suddenly rose on the school field, and the fire seemed to come in the direction of the gold and jade.

Shen Yifan shouted at the top of his voice: "Quick! Climb up. ”

Such a complex mechanism pass will naturally not be stuck by a few logs and stop running, and after the mechanism in the city stops running, the backup mechanism in the urn city will also be activated, and the backup mechanism is an upgraded version of the feather arrows are all on fire, and the soil in the school yard is mixed with a lot of animal ointment fat ignited when it is fired, and suddenly a wall of fire spreads along the school field.

Fortunately, Jin Zhuyu and the others also moved quickly, and finally a motor took Gu Jie up to the main city together, and then looked down and saw that there was already a sea of fire in the urn city, and watched the fire still spread upward along the wall of the main city.

Fang Zi touched the city wall and shouted, "I'll go—the city wall is full of ointment." ”

Shen Yifan shouted: "Hurry up—go to the city tower." ”

In ancient times, there was a castle tower on the city wall, which was used as a command center for the general to command the city defense battle, and there was also such a castle tower on the pass city, and everyone was cold in their hearts after entering the castle tower. There are many clay jars neatly in the city tower, and after opening the clay jars, a strong aroma of wine overflows.

The expert quipped: "Are these ancient celebration wines?" ”

Shen Yifan looked inside and said, "It's already a wine ointment." These ointments burn when they are on fire. So much liquor paste is a giant bomb. Shen Yifan then said: "I don't know if these wines were celebratory wines in ancient times, but now they are definitely our guillotine wines." ”

Shen Yifan said: "Find a way out." Before the words were finished, Sanniu and the motor had already run in from outside the city tower and said, "The fire has burned. Shen Yifan looked outside and was also shocked, and saw that the fire was burning towards their city tower at a speed visible to the naked eye, and it was estimated that it would burn the city tower in less than ten minutes.

Sanniu and the expert also ran over at this time and said: "This is a dead end, there is no way out at all." ”

Shen Yifan's heart was half cold suddenly, and his brain was also blank at this time, and he didn't know what to do? At this moment, Jin Jianyu shouted: "There is a man there! ”

Shen Yifan followed the direction of the golden jade finger, and saw a man in black walking in the direction of the organ city with an almost flying attitude, with a ball of cable on his back, his posture was almost like flying up against the wall, and if you looked closely, you could see that his hands and feet could jump several meters above the wall just by jumping a little on the wall.

Shen Yifan's heart lit up when he saw this, and shouted, "Go to the corner in front of you." As soon as the words fell, he saw that the shadow man had already gone up to the wall, and shook one end of the bundle of cables with the posture of a western cowboy horse, and landed firmly on the battlements on the main city wall, tightening the ferrule and pulling the cable tight.

"Hurry-hurry-hurry." Shen Yifan said three quick words in a row, urging everyone to climb along the cable.

There is only a distance of about four or five meters from the corner of the main city where Shen Yifan and others climbed the cable to the organ city, but the time for everyone to crawl on the cable seems to be very slow, and this experience makes everyone very difficult. Underneath the rope was a raging fire, dangling the rope and feeling like it was going to fall down at any moment.

Shen Yifan was the last to get on the cable, at this time the fire had spread to the main city tower, and he could already smell the smell of wine being roasted by the fire, and a stronger aroma of wine filled the entire main city wall. Stone; The tiles flew in all directions with a sticky ointment, and for a moment it felt like the entire air was filled with debris from the explosion.

Shen Yifan's climbing rope also became two sections with the explosion, Shen Yifan grabbed one end of the cable like Tarzan, and the soles of his feet were almost attached to the flames to the edge of the city, because it was an emergency, Shen Yifan's body did not adjust his posture, but when his body hit the city wall, his hands did not grasp it steadily, and the whole person fell down at once.

The place where Shen Yifan fell was not somewhere else, it was a moat between the main city and the organ city, and the whole person plunged directly into the river without stopping at all, Jin Jiaoyu and the others didn't see Shen Yifan come out after looking at the splash on the moat, and they didn't see him come out again after looking at him for a long time.

Jin Jianyu and the others were reluctant to leave, and they still looked at the moat on the city wall, but when the river level calmed down, there was still no shadow of Shen Yifan, which was Jin Jianyu began to panic a little, and she now began to feel that Shen Yifan might have encountered an accident.

The Shadow Man said coldly, "If you want to die here, stay here forever." If you want to live, follow me. ”

Everyone looked at Jin Jianyu and then looked at the black shadow man, of course, he didn't know the black shadow man, so he naturally wouldn't listen to the black shadow man, and after a while, Jin Jianyu gritted his teeth and said, "Let's go." ”

Everyone looked at the gold inlaid jade puzzled, and the gold inlaid jade iron said with a blue face: "I said let's go." ”

Ah Bing naturally listened to the gold inlay jade, and Gu Jie's injury was already very serious, so he couldn't stand the toss here, so he helped Gu Jie leave with the black shadow man without saying a word, and then the gold inlaid jade. Motor; Sanniu and the others stopped for a few minutes and looked at the crumbling main city wall in front of them, knowing that this place would soon collapse in the fire, so they could only grit their teeth and leave.

The black shadow man took everyone to the Qianlong Ping, where Murong Wan'er was resting, and everyone was relieved, and none of them spoke, just sat on the edge of the fire, looking at the fire one by one.

At this time, Murong Wan'er had already woken up, and when she saw that there was no Shen Yifan, she was the only one who was very nervous, and asked a few times, but everyone did not answer.

Murong Wan'er looked at Jin Zhuyu and them with very frightened eyes, and said in her mouth, "Won't he come back?" ”

Everyone didn't know how to answer this question, so they had to choose silence.

However, the Shadow Man said something very uplifting: "If he dies like this, then he is not him." ”

Although the words of the Black Shadow Man lifted everyone's hearts, it also made everyone suddenly remember that there was such an uninvited guest, and suddenly everyone jumped up from the spot as if they were electrocuted, raised their weapons and aimed at the Black Shadow Man.

The Black Shadow Man sneered, and when his laughter was over, he was slowly removing his veil, and a face that surprised everyone appeared in front of everyone's eyes.
