Gao Moli found a shallow arrow sign on a rock wall, which was left by Gu Yixin, indicating us to move on.

I continued to crawl down the mine for twenty minutes, but there was no way.

The Black Bull knocked on the rock wall at the end of the mine with a large black eagle, leaving several bright red marks on the shallow rock formation.

Behind the brown rock formations is unexcavated ore, and it seems that the road has indeed come to an end.

The black bull said puzzledly: "It's weird, what's the matter, this is the end?" What about them? And the ancient building, I thought this road would lead to the ancient building! ”

"When you look at it from below, there seems to be no entrance on either side of the ancient building! Otherwise, the color of the entrance should be darker than the shadow of the building, and it should be distinguishable at a glance. I turned to say, "However, if there is no entrance, how did Zhang Xuefeng and Gu Yixin get in?" I think there may be a secret door in the wall of this cave. Also, this secret door should be able to be opened and closed. ”

With that, I used tactical spotlights to look around, and it was gray, and there wasn't even a crack in the cave wall.

When he was at a loss, Gao Mo walked to the side of the cave wall from Gu Zi, opened the wolf's eye, took a picture of the cave wall, and then swung the three-edged sword to cut off a large piece of rock on the cave wall.

"Come and have a look!" He beckoned me and the black bull over.

I thought he had discovered the secret door, but when I got closer, there was the ancient building inside the red agate ore rock.

From here, it seems that the ancient building is close at hand.

Directly opposite us was the corridor on the second floor, and we saw Gu Yixin walk into a room, and a few seconds later, he walked out of another room and continued to walk with his back to us.

I wondered: are the interiors of this room interconnected? She seems to be looking for something?

We chased Gu Yixin all the way, and now that we were so close, I couldn't help but bend down and touch a piece of agate primordial, and knocked the cave wall.

The sound of percussion echoed through the cave, deafening.

Gu Yixin stopped abruptly and glanced back, her gaze was just looking in the direction where we were.

Her strands of hair were clearly visible, and it seemed that we were no more than 100 meters apart.

I threw down the rough stone and waved my hand at her.

Strangely, Gu Yixin only glanced in the direction we were, then turned around and continued to walk forward.

Hei Niu said puzzledly: "Why, Xiao Gu doesn't seem to see us?" However, let's see her clearly! Is she really not seeing, or pretending not to see? ”

While speaking, there was a sudden dark shadow in the ancient building above us, and I saw Zhang Xuefeng walking out of another room on the third floor with Thompson in his hand.

The tall mercenary followed Professor Kang, whose head drooped and he couldn't tell whether he was dead or alive. We looked closely, but we didn't see the short mercenary, the tomb was dangerous, and it was estimated that he had already hung up.

Gao Moli only glanced at the phantom of the ancient building for a few moments, then stepped aside and continued to observe the cave where we were. He may also think that there should be a secret door here that leads to the ancient building.

In the ancient building in front of them, Gu Yixin and Zhang Xuefeng were walking on different floors, and they seemed to be looking for something.

Hei Niu looked at the scene in front of him, and suddenly said, "Old Su, it's not right, why is Xiao Gu in the ancient building with Zhang Xuefeng?" Is there something wrong with her? ”

I know that Hei Niu is suspecting that Gu Yixin and Zhang Xuefeng are together, but at the moment, he is not very sure, so what he said is more vague.

I thought for a moment and said, "No, if they were a gang, Gu Yixin wouldn't have left a mark for us." ”

"Then why did she pretend she couldn't see us?" Black Bull asked me.

Without waiting for me to answer, I saw Zhang Xuefeng suddenly lift Thompson up, shoot at the room, and then run away with the tall mercenary and hide in the room where he is out of nowhere.

We only saw the fire from the shells, and we didn't hear a sound at all.

Gu Yixin didn't seem to hear the sound, and Gu Zi walked in the corridor.

Thinking about it this way, just now, Gu Yixin may not have heard my tapping sound, and her movement of turning around may be just a coincidence.

"It's not safe in this building! We must find Gu Yixin as soon as possible! ”

As soon as he finished speaking, there was a loud grinding sound on the ground of the mine.

Hei Niu and I hurriedly looked, only to see Gao Moli turning a square machine stone, which was hidden in the pile of original stones, which was very difficult to detect.

As the trapstone turns, a circular pit opens in the mine's floor.

That pit must be a secret passage to the ancient building.

We didn't have time to think about it, so we got into it one after another. The secret passage was only allowed to pass through one person, and after crawling for a distance, the secret passage was divided into three forks.

Seeing these forks, I suddenly understood that each floor of that ancient building was relatively independent, and it was no wonder that although he was in the same building, Gu Yixin couldn't hear Thompson's shooting.

Gu Yixin was on the second floor of the ancient building, and we resolutely crawled towards the fork in the middle.

After crawling for more than ten minutes, I turned up, and the dark passage had come to an end.

Sealing the secret passage is a huge persimmon red agate, the agate stone is like a flat sewer manhole cover, carved with tired auspicious clouds, as if as long as you reach out and push it open, the door to the heavenly palace will be opened.

Gao Moli stretched out his hand and was about to push away the sealing stone, when suddenly, a beam of light flashed on the ground, and a faint black shadow walked over.

Seeing this, Gao Moli took his hand back and turned off our spotlight while touching his triangular sword.

I felt strange behind Gao Moli, so I reminded: "Let's go out quickly, it may be Gu Yixin." ”

The sound of "boom" stampede sounded above us, and the light and shadow swept aimlessly around. In my judgment, this secret passage may be located under the room of the ancient building, and it is no wonder that when we looked up in the mine, we did not find that there were entrances on both sides of the ancient building.

The footsteps were getting closer and closer, and I looked carefully through the beam of light on the ground, and the person walking on the ground was Gu Yixin.

I was overjoyed, and quickly stretched out my arm to push open the door of the secret passage.

Gao Moli grabbed me, lowered his voice and said, "There is another person." ”

"Huh?" I was amazed, thinking to myself, the three floors of this ancient building are independent of each other, only Gu Yixin is on the second floor, and Zhang Xuefeng is on the third floor. In addition to Gu Yixin, how can there be another person here?

I knew that Gao Moli was extremely hearing, and since he said that, he must have noticed something unusual. I held my breath and cowered into the hole to watch the movement on the ground.

Sure enough, the sound of walking sounded on the ground again, and the sound came from far and near, and every step was very determined.

At the same time, Gu Yixin, who was standing above us, turned off the tactical spotlight all of a sudden, and hid behind a huge black shadow, looking at the outline of the black shadow, it should be a large box with a long direction.

Could it be that Gu Yixin was being followed?

Another beam of light shone in from a distance, and that beam swept around the room, as if searching for something.

The black bull squeezed tightly next to me, looking at the constantly shaking beams, and the atmosphere did not dare to come out, for fear of alarming the people on the ground.

As the figure drew closer, I looked at it with wide eyes, and suddenly felt that the shadow was very familiar.

The light and shadow were refracted by the ground and reflected on the man's face.

I was suddenly shocked in my heart: Isn't this Gu Yixin? Didn't she just come in? How...... Why did you come in again?
