"Miss-" Ah Zhen let out a heart-rending scream at the sight of this qiē, and even the sound of falling rocks that kept sliding in all directions could not hide her sharp scream.

In the chaotic sound of the rocks rolling, Shen Yan'er's body was engulfed under the falling rocks in the blink of an eye. The flying dust filled the entire tunnel, as if a sudden dense fog had appeared, spreading into the distance, and soon reaching the tip of Ah Zhen's nose.

Ah Zhen was choked and coughed constantly, and the tears that kept slipping down couldn't tell whether they were choked or cried. "Miss—" Ah Zhen roared wildly, no longer caring about the sharp pain in her calf, dragging her barely able body to crawl forward.

After the loud bang, the smoke and dust that dispersed in the tunnel gradually dissipated, and all of them fell silent. Ah Zhen, whose throat was screaming in pain, couldn't scream anymore, she crawled forward in pain, her eyes kept staring at the place where Shen Yan'er disappeared, letting the tears fall down.

Suddenly, two faint coughs came from under the stone that hit Shen Yan'er. Ah Zhen was stunned for a moment, unable to believe her ears. She immediately concentrated all her attention, staring intently at the stone that covered Shen Yan'er's body.

"Ahem......" Two more coughs, clearer than just now. It's not Ah Zhen's auditory hallucination, but it's real, it's really Shen Yan'er's voice.

Ah Zhen didn't have time to be moved, and there were tears in her eyes, and she saw the grizzled Shen Yan'er slowly crawling out.

It turned out that the stone did not hit Shen Yan'er, but on the stone standing up behind her. It's called "the sky is falling, and a tall man is in the way." She was in the triangle between two stones, and she had eaten only a pile of ash and no wounds.

"Miss!" Ah Zhen shouted excitedly. The walking corpse in the distance also let out a crazy howl after hearing her cry, but at this time, Ah Zhen couldn't care about being afraid, her heart was full of joy, and even felt that the roar of the walking corpse sounded like a celebration.

"Oh my God, I, ahem, I'm fine...... Shen Yan'er, who crawled out from under the stone, touched her body and limbs, and even she was startled when she found that her whole body was intact.

To be honest, the moment the stone fell, Shen Yan'er really thought that she would be smashed in the head and die on the spot, but she didn't expect to be lucky to survive, thank God.

Seeing that Shen Yan'er was safe and sound, Ah Zhen breathed a sigh of relief. All the strength that had just been mustered was gone, and only the exhausting body and the sharp pain in the legs were left. "Miss, how was the road blown up?" Ah Zhen asked anxiously.

After hearing Ah Zhen's words, Shen Yan'er reacted, and hurriedly turned her head to look in the direction of the stabbing array, but what she saw was a disappointing scene. Although a lot of rocks had fallen just now, most of them had fallen nearby, and the road to the opposite pit wall was still impassable.

"It doesn't matter, we still have gunpowder, we can try again." Shen Yan'er used her hands and feet together, and crawled through the small hill made of broken stones. There were many wounds on her limbs from the edges of sharp stones, but she didn't feel any pain at all, and all she thought about was how to save Ah Zhen and how to catch up with Pan Yuting.

When Ah Zhen heard that Shen Yan'er was going to smash it again, she immediately said worriedly: "Miss, you hide, let me come." Anyway, I only have half a life left, and instead of waiting to die, I might as well use this half life where it should be used. Saying that, Ah Zhen held on to the stone and wanted to grit her teeth and walk over, but her right leg, which was unable to use her strength, could not stand up.

Shen Yan'er was worried that she would be injured and injured by falling into the stabbing formation again, so she hurriedly shouted, "Slow down, don't come over", and sped up to crawl back. As a result, at this time, Shen Yan'er suddenly caught a glimpse of a "strange thing" out of the corner of her eye.

The "thing" was a black iron rod more than half a meter long, with a semicircular mechanical object inserted at the lower end and a wooden handle at the upper end. It looked as if you could grab the wooden handle and use the semi-circle as a fulcrum to press the iron down entirely.

The iron rod was behind the wall that was blown up by Shen Yan'er just now, so Shen Yan'er didn't find it before. After a few days of exercise, Shen Yan'er understood a truth: everything that appears in the mass grave is for a reason, and all the designs are exquisite and meticulous. So, naturally, this iron will not appear in this place for no reason, and there must be something to do.

Thinking of this, Shen Yan'er turned around and approached the iron step by step. As the distance gradually narrowed, Shen Yan'er took a closer look through the faint light of the fire, and finally vaguely saw in the darkness that there were still many complex mechanical structures behind the iron.

Irons, gears, chains, bearings, and many other things that Shen Yan'er can't name. Shen Yan'er, who didn't understand machinery, was stunned by the spectacular scene in front of her and was dumbfounded.

Although Shen Yan'er couldn't figure out how these things worked, there was one thing she understood. That is, the iron rod at the front is the switch that controls the qiē.

Just pull down the iron rod and the whole machine can be started.

"Ah Zhen, we can go out......" Shen Yan'er's voice sounded weak, this was because she was already exhausted, but this did not affect the excitement in her heart in the slightest. If she had been given a little more strength, she would have jumped with excitement.

"The stabbing array should be mobile! Great, Jane, I should have thought of it. The Thorn Array is located at such a deep place, the Royal Forest Army can't jump down and pull out the walking corpses one by one and transport them up. The mechanic was so clever that it was impossible to leave such a big fail. I see, I see, so it is, so it is......"

Shen Yan'er's heart suddenly brightened, her speed of speech became faster and faster because of excitement, and the heavy despair caused by the predicament disappeared in an instant, and she felt that her whole body was as light as a feather, as if she could float.

If Shen Yan'er didn't guess wrong, as long as she pulled down that handle, the entire thorn array would automatically move up to the ground. This was actually designed to make it easier for the Guards to sweep the walking corpses from the Thorn Formation, but now they could save her.

The mechanic was so thoughtful. knew that the mechanic was the culprit who caused her to fall into such a situation, but Shen Yan'er still couldn't help but secretly admire the person who designed this qiē in her heart.

"Miss, what did you say?" I heard Shen Yan'er chirping and muttering a big call, but Ah Zhen in the distance didn't understand anything, staring stupidly at Shen Yan'er, who was so excited that she couldn't even speak.

There was no time to explain in detail, Shen Yan'er crawled along the gravel mountain with her limbs like a puppy, and came to the iron as fast as she could. She gripped the wooden handle, took a deep breath, and pulled down the iron with all her strength.

At this moment, the ground under his feet suddenly shook violently.
