At this moment, Chen Ziyang really fell hard, he fell and ate, and lay on the flat ground with his limbs spread. Feeling the surrounding terrain, Chen Ziyang knew why he fell, it wasn't that something tripped him, but that these endless steps had finally reached the end.

When a person running down the stairs suddenly ran to the end of the stairs, the darkness in the vicinity severely limited the view. The man did not see the end of the steps at all, and in such a situation, having become accustomed to the previous steps, suddenly stepped on the flat ground without steps, and the part of the flat ground that was above the steps would trip over the running man like an obstacle.

At this time, Chen Ziyang was like this, the sudden appearance of the flat ground caught him off guard, coupled with the previous high-speed running that made his blood surge, Chen Ziyang only felt that his breathing was rapid and dignified, his heart was beating faster, and his whole face under the gas mask was hot, and at the same time, his brain was groggy, and he didn't know if he had broken his head.

In the process of running, he ran out of strength, and at the same time, coupled with the fall, Chen Ziyang tried several times and did not get up from the ground, so he had to lie there quietly and listen carefully, hoping to hear the voice of Umbrella Shishuai. But he listened for a long time, and there was no sound other than the sound of his own heavy breathing under the gas mask.

Your sister, this time I came to Inner Mongolia, everything really didn't go well, I went crazy with Yang Lei first, and this time I lost the umbrella Shishuai. But fortunately, after a while, Chen Ziyang's brain regained a trace of clarity. He quickly turned on the switch on the oxygen cylinder on his body.

When the switch is turned on, the gas mask switches from filtration mode to oxygen mode. Take a big breath of the cool oxygen mixed with the unique taste inside the cylinder. Chen Ziyang felt that his brain was becoming more and more awake, and at the same time, his body was becoming more and more powerful.

The air in this tomb was already very turbid, and he needed to wear a gas mask to be able to breathe, and the amount of oxygen inhaled after being filtered by the gas mask was relatively small, coupled with Chen Ziyang's extreme running just now, it depleted the oxygen in his body, causing his body to have a hypoxic reaction, so it caused his brain to be unconscious just now.

Fortunately, Chen Ziyang practiced the Qigong taught to him by Lao Lu, and his body functions could function much better than normal people in a state of lack of oxygen. Otherwise, it is very likely that he will fall to death from lack of oxygen at this moment.

After feeling that his breathing was gradually normalizing and his heart rate had also dropped, Chen Ziyang closed the valve on the oxygen cylinder. After greedily breathing in the last few breaths of oxygen remaining under the catheter and oxygen mask, Chen Ziyang got up from the ground.

The oxygen cylinder that Liu Cong distributed to everyone in the team is not very large, and the weight is relatively light, in order to be easy to carry and not consume too much physical strength of the team members. Because this oxygen cylinder can be refilled with oxygen from the huge liquid oxygen tank that Saburo carries inside, it does not need to be too large, and as long as Saburo is present, there is no need to worry about running out of oxygen in a short time.

But not now, Liu Cong and they will probably not be able to find themselves at all, so it is better to save some oxygen. Chen Ziyang turned on the communicator in the gas mask, but just as he feared, his call was not answered, and he didn't know if the communicator had been broken just now, or if it was out of range.

Picking up the hundred slashing sword and flashlight that fell aside, Chen Ziyang tried to turn on the switch of the flashlight, but the flashlight did not light up. grabbed the flashlight and tapped it his other palm a few times, and the light from the flashlight flashed a few times before finally lighting up, adding a trace of confidence to Chen Ziyang.

Using the flashlight to shine around the surroundings, Chen Ziyang didn't see anything other than the ground, not even the countless steps he had run before. It seems that this time because of his excessive force, he is already a few meters away from the last step.

Okay, Umbrella Shishuai was lost, communication with Liu Cong and them was interrupted, they were separated from the team, and now even the direction is lost. If people are unlucky, they will stuff their teeth when they drink cold water, the meaning of this sentence Chen Ziyang now completely understands, no wonder he felt restless when he arrived at the damn place of Ghost Howling Slope before, and this feeling is getting stronger and stronger, and now Chen Ziyang understands that this place is really not his blessed land.

At this time, you must not move, otherwise it is likely to backfire and fall deeper and deeper. Anyway, there is no clue about Umbrella Shishuai for the time being, it is better to find the steps first, so that you can have a reference, so Chen Ziyang thought about it carefully.

He squatted down and looked carefully at the ground he was stepping on, the ground was very flat, and there were concave marks on the ground here that were either round or long. The material of the floor should be the same as that of the steps, which is similar to the stone of volcanic rock.

Now Chen Ziyang can be sure that these steps and the ground are not paved with volcanic stones brought from elsewhere. Rather, this is a huge area of volcanic rock, and those steps and ground are built on this volcanic rock that already exists here, otherwise this large amount of work is unimaginable, and it is no wonder that this place is so big, and there are so many steps here.

Touching the items he was carrying, Chen Ziyang then thought of a way, he took out the knife on his body, tied one end of a red thread after the Five Emperors Coin to the knife of this knife, and then inserted the knife into a gap in the ground.

Immediately afterwards, Chen Ziyang took out another red thread and connected it to the other end of this red thread, so that Chen Ziyang used two red ropes nearly five meters long to make a huge compass for himself, which can draw a circle with a radius of ten meters with a knife inserted in the ground as the center of the circle.

With a radius of ten meters and a range of five meters that he can see, Chen Ziyang can directly search the area within fifteen meters nearby, and he will not lose his way while searching, even Chen Ziyang himself was stunned, how could he think of such a clever method, it is very likely to have something to do with the pure oxygen he inhaled just now.

Finding a random direction, Chen Ziyang walked over until he straightened the red thread in his hand. In this case, I was almost ten meters away from the place where I had just fallen.

Then Chen Ziyang gently pulled the red rope to keep the red rope in a slightly tight state, and then he carved an X-shaped pattern on the ground with the Hundred Chopping Sword, and after inserting the Hundred Chopping Sword into the waist, Chen Ziyang walked up.

As he walked, Chen Ziyang paid attention to the strength of his pull on the red rope, fearing that he would use too much force and cause the knife inserted in the ground to pop out of the gap. At the same time, he used his flashlight to shine on the outside of the center of the circle. Carefully inspect the situation within five meters of himself.

When Chen Ziyang saw the X-shaped pattern carved by himself on the ground again, he knew that he had walked a full circle. But within the scope of this circle, Chen Ziyang did not find anything. It seems that he fell farther than he imagined. Originally, Chen Ziyang thought that the position he was in before was not very far from the last step, and the search distance of 15 meters was enough, but now it seems that he was careless.

Returning to the place where the knife was inserted, Chen Ziyang stepped on it a few more times, and firmly fixed the knife that had been crooked by him to the ground again. According to the method just now, Chen Ziyang tied another red rope to the back of the red rope, the length of the red rope of fifteen meters plus the visual range of five meters, so that he could search for a range of twenty meters nearby.

Just when Chen Ziyang hesitated whether the search range of twenty meters was enough, whether to tie another red rope and directly expand the search range to 25 meters, he suddenly had an ominous feeling, and felt a trace of coolness coming from his back spine.

Your sister's has an evil thing!
