Ever since the procession reached the bottom of the wall, no one had crossed the wall in front of them. And now the camera clearly captured a wrist-thick hemp rope tied to the battlement on the other side of the seven or eight meters wide city wall, which means that someone should have reached the top of the city wall before.

"It seems that your previous guess is not wrong, Zhang Taixu and Wang Dingqian should have crossed over from the top of the city wall, so there is a rope tied there." Finally found a way to cross the city wall and enter the city, Liu Cong was relieved.

Seeing this hemp rope, Chen Ziyang also relieved his heart, and finally found the right path to prove that his previous guess was not wrong, otherwise even if Chen Xin died in vain, he would really become the sinner who killed him.

After getting the picture she wanted, Liu Cong asked Xu Xiaoyuan to come down from the city wall, after all, after such a long time, her physical strength should have been exhausted. Although it seems that Zhen Hao now knows what is going on on the city wall, it still takes time to figure it out, and it is impossible for Xu Xiaoyuan to hang on the city wall all the time.

Xu Xiaoyuan, who heard the retreat order for the second time, made a very fatal mistake.

She had been lying on the city wall, she felt very nervous, and then finally heard Liu Cong's order to let her retreat, Xu Xiaoyuan's tense nerves relaxed suddenly, but before she could make a downward movement, Liu Cong asked her not to move, and continued to hold the camera.

At that time, everyone saw the rope at the other end of the city wall from the picture, so Xu Xiaoyuan was asked to readjust the angle of the camera, although the people standing under the city wall did not think that this was a dangerous thing. But they ignored one point, that is, Xu Xiaoyuan, who was above the city wall, didn't know what was on the city wall.

She didn't know that what Liu Cong and the others wanted to see was just a rope tied to the city wall, and thought that some danger was approaching her.

It was in this state of mind that Xu Xiaoyuan was nervous and did not move, for fear that his slightest movement would trigger the mechanism or be attacked by a giant python. In this state of forced stillness, her physical strength accelerated, and at the same time, she felt a chill in her hands.

When people are nervous, the blood will naturally rush to the legs, and the blood entering the legs can make the legs more powerful, so as to escape quickly, which is the result of the body's self-regulation when people feel fear, and it is the instinctive reaction of people.

I don't know if it's because a large amount of blood flows to the legs, causing cerebral ischemia, or because it turns into relaxation in a state of tension and re-tenses in a relaxed state, Xu Xiaoyuan actually forgot Zhenhao's instructions before.

When she was about to go down from the city wall, she naturally put her hand on the wall between the two battlements, hoping to use this strength to make it easier for her to descend.

Just when Xu Xiaoyuan's hand just touched the city wall, she suddenly felt as if she had pressed something softer, and this thing moved down a short distance under the pressure of her fingers.

This sudden fright instantly scared Xu Xiaoyuan out of a cold sweat, and she remembered what Zhen Hao had said before, but it was too late now. A cool breeze blew in his face, and Xu Xiaoyuan saw a huge shadow appear in front of him in an instant.

If it was someone else at this time, he would definitely be engulfed by this black shadow in an instant, but Xu Xiaoyuan's reaction speed was very fast.

When she had just pressed the soft thing on the city wall, her heart was shocked, and she knew it was not good. Although the matter was irreparable, she was already prepared at that moment.

Seeing the sudden black shadow, Xu Xiaoyuan knew that it was too late to dodge down at this time, but the black shadow in front of her came very quickly, and she didn't give her too much time to think at all, so Xu Xiaoyuan immediately let go of her hand holding the rope, and with a fierce force of her legs, she jumped a large distance on the city wall horizontally.

The moment she let go of the rope, she had already thought of a way to deal with it, so Xu Xiaoyuan did not completely loosen the rope, but slightly relaxed the strength in her hand, and let her fingers form an "O" shape, and the rope was still in her hand.

After moving sideways for a distance with the power of her legs, Xu Xiaoyuan felt that her body was no longer moving to the side, but was about to fall down, and at this time, a black shadow brushed her body dangerously and dangerously, and landed where she was just now. Immediately after, the black shadow instantly retracted into the city wall.

From beginning to end, Xu Xiaoyuan didn't see what was attacking her. After feeling that she was swimming between life and death, she hurriedly grabbed the rope in her hand again, and used the power of the rope to prevent herself from falling under the city wall.

Then Xu Xiaoyuan stared vigilantly at the city wall above, and quickly followed the rope down, and soon got out of the dangerous area.

After her feet landed, she felt her whole body weak, and the feeling of collapse came to her. After his feet were weak, Xu Xiaoyuan fell to the ground. Chen Ziyang hurriedly ran over, picked her up with both hands, and carried her back to the team.

"Get out of here, Xiao Yuan, are you okay?" After snatching Xu Xiaoyuan from Chen Ziyang's hands, Jia Da scolded and no longer paid attention to the others, but cared about the injuries on the body of the Dao Gu.

The thankless Chen Ziyang also ignored Jia Da, as long as Xu Xiaoyuan was fine, the woman who could stand up at this time was already very admirable.

Xu Xiaoyuan had already won Chen Ziyang's heart and the respect of others, and at this time, everyone felt that the angry words that Jia Da said before were not so important, after all, his apprentice had helped everyone a lot.

Seeing that Xu Xiaoyuan was only overly frightened and did not suffer any injuries, Chen Ziyang hurriedly gathered together with Liu Cong, and a group of people surrounded Zhen Hao and interrogated him like a prisoner.

"I saw just now that the rope on the battlement on the other side of the city wall is tied to the upper edge of the battlement, and you also said this to Daogu at the time, you must let her tie the rope to the upper edge of the battlement, and don't touch the city wall between the lower edge and the two battlements, how do you know?

Also, how did you know that the traps on the walls were hidden in the dead corners under the battlements? Liu Cong couldn't wait to ask this series of questions.

If the person being interrogated at this time was Yang Lei, he would definitely put on an unfathomable expression, then lit a cigarette, and said it slowly and logically, and he couldn't get to the point. But Zhen Hao's personality is the opposite of Yang Lei, this person is very stable, and he doesn't talk much, so he directly says the point.

"Speaking of this, you shouldn't thank me, but Chen Xin."

"Chen Xin? He...... Isn't he dead? Yasheng heard Zhenhao mention Chen Xin, thinking that Chen Xin was alive again, but she felt a chill down her back, and hurriedly turned her head to look at the stone platform in the distance, and saw that the three corpses were still parked there, and she breathed a sigh of relief.

"He's dead, but after he died, he helped us find important clues." After saying this, Zhen Hao broke through the crowd and led a group of people behind him who were eager to get an answer to Chen Xin's body.

"Look here." After saying this to Chen Xin's headless neck, Zhen Hao stood aside and said nothing, and the others gathered around.

Although it was a little scary to stare directly at a headless corpse, everyone wanted to satisfy their curiosity.

There was a large pool of blood next to Chen Xin's corpse, some of the blood stains seemed to flow out of the corpse, while the other part was of different depths, showing traces of finger width, which should have been smeared by Zhen Hao's adherent blood that had not yet coagulated, and there were several relatively regular lines on this pool of blood.

A long string of "several" characters are connected together, which looks like stacked mahjong tiles, but everyone knows that this pattern should represent the battlements on the city wall.

Behind this line there are four side-by-side rings, two of which are a complete circle, while the other two are missing a small piece that looks like the rings have their mouths open.

Staring at this pattern, Chen Ziyang felt that this pattern looked like the Pac-Man in the Pac-Man game of Nintendo Red and White Machine that he played when he was a child.

At the same time, there are small dots on the string of "several" characters, which are covered with the lower edge of the battlement and the city wall between the two battlements, but not on the top of the battlement.

After staring at the pattern for a while, everyone looked up at the city wall again, and everyone figured it out.

The meaning of this pattern is to tell the viewer that there are balls hidden in the dead corners behind the battlements, and that the mechanism of the balls is triggered by the buttons placed on the lower edge of the battlements and the wall between the two battlements.

Probably because the placement of these buttons requires space, there is no way to place them on the edge of the buttress that is only twenty or thirty centimeters wide, which is why Zhenhao asked Xu Xiaoyuan to tie the rope there, because it is the only safe place.

After resting for a while, the recovered Dao Gu also walked into the crowd. Chen Ziyang told her all the causes and consequences of the incident. After knowing that it was the rope that was tied to the city wall before that scared him, Xu Xiaoyuan couldn't cry or laugh.

Although the whole thing was a false alarm, it was this false alarm that almost killed him, and almost ended up with the same fate as Chen Xin, thinking of this, Xu Xiaoyuan really felt worthless for himself.

"It is estimated that after Zhang Taixu and Wang Dingqian cracked the mechanism on the city wall, they engraved the hint on the base under the wordless monument, but because no one has passed here for so many years, a thick layer of dust has fallen on the stone platform, so we didn't notice these patterns before.

However, by chance, Chen Xin's body was placed here by us, and his blood revealed the secret for us, and he died well. Staring at the pattern in the pool of blood beside Chen Xin, Guo Huaxing said thoughtfully.

"Alright, the mechanism has been cracked, the rope has been tied, and there is still some time to climb over the walls.

It's too cold here, there are a lot of houses inside the city wall, maybe we can find a warmer place, let's hurry up and enter the city, don't waste time here. Zhang Linfu reminded Liu Cong.

The mechanism on the walls had been cracked, and the ropes had been pulled, and it was only a matter of time before the team climbed over the walls.

There was no way to take away the bodies of Chen Xin's three people, and the group bowed three times to the three corpses, and then let them park on the stone platform under the wordless monument, accompanied by the towering wordless monument.

Li Linzhi still hasn't woken up. The previous hit was so bad that it was estimated that she would not be able to wake up in a short period of time. Yang Lei kept muttering, and he didn't know if he had knocked her out of a concussion this time, and it would be miserable if she woke up and became crazy.

Soon, one by one, the people in the team climbed to the top of the city wall with the ropes from the city wall, and everyone took care to avoid the traps above when crossing the battlements.

On the inner side of the lower edge of the battlements and on the wall between the two battlements there is a row of square buttons of the same color as the wall, each of which is not too big, and when connected together, it covers the entire wall, and if someone puts a hand on the wall, it will definitely touch.

Although they knew that as long as they didn't touch these buttons, the pitch-black balls under the battlements of the city wall would no longer be lethal, but everyone was still cautious when stepping over them.

Looking at the thing that almost cost her life before, Xu Xiaoyuan felt that she was not wronged by the fright. This mechanism is very cleverly designed, and at the same time the mechanism is also very powerful, although we know that these iron balls are hollow, but even hollow iron balls should be heavy.

However, such a heavy iron ball did not make a sound when it stretched out of the city wall after the mechanism was triggered, and only a cool breeze could be felt, and under the cover of the dim environment, these iron balls could really be called killers hidden in the night.

Two of the four chains protruding from the orb are supposed to be used for the orb to attack downwards, and after the orb attacks, the other two chains that reach into the wall will pull the orb back.

It seemed that the trap could be recycled forever, and that it was still effective after all these years, and everyone was impressed by the creator of the trap, and knew that there was a good chance that the team would face even greater danger.

Countless iron balls stretched out into the darkness one after the other. Liu Cong estimated that Chen Xin's head was inside a certain iron ball, but he didn't plan to look for it, after all, Chen Xin was dead.

If you touch something while you're looking for it, it's not good if you hurt other people. So he set his sights on the thick hemp rope tied to the buttress on the opposite side.
