This portable oxygen cylinder was originally intended to cope with the shortage of air in the cemetery, but because of its heavy weight and the capacity of the air inside can only last for up to 15 minutes, not everyone will carry it, and even I didn't carry it a few times.

But this time it came in handy.

The current situation will inevitably have great restrictions. There are 20 people here, and it is not very likely that this will last forever under such a large range.

I slowly put the mask connected to the oxygen cylinder on my face.

After being able to feel the connection between oxygen, my spirit becomes much more energetic.

As the oxygen continued to inhale, I could vaguely feel my nose itchy, and the sense of smell that seemed to have been blocked was gradually returning.

Not only did I feel the vague feeling and hearing in front of my eyes, but I also felt a lot better, which made me smile involuntarily.

It seems that what I guess is indeed correct. The most important thing that leads to such a situation now is what is permeated in the air.

These things only work in a short period of time, and as long as you do not inhale air within a period of time, you will return to normal.

But my face immediately became extremely solemn. Now I only have about 15 minutes, and now I have to seize the time to quickly solve the things in front of me.

After slowly concentrating my mind, I immediately continued to move forward.

Based on what happened when going up the mountain at this time, visual blur has appeared, and it should be less than half the distance left to the real culprit.

Pull the backpack apart, just take the composite crossbow and a bronze dagger, and put the rest on the ground.

Then put the oxygen cylinder back into the backpack and left only a pipe leading to the mask on the mouth.

I almost maintain the maximum speed I can reach at the moment. Although the oxygen consumed under the violent running will reach the extreme, there is no other way now.

The oxygen in the oxygen cylinder is highly compressed and can be used for a period of time. The oxygen consumption in the tomb can be considered relatively large and can last for 15 minutes.

Even if I am running at a height like me, I should be able to last for about 12 minutes.

In such a situation, the best way is to slowly reduce oxygen consumption. However, this method can be said to be unworkable in the current situation.

Now the surroundings are filled with danger at any time. Under such a vigilant state, the blood and heartbeat are very fast, and the oxygen consumption is naturally fast.

Even walking in the same state consumes more oxygen than normal.

If this is the case, it is better to run at full speed. In this state, the oxygen consumed should be about the same as usual.

The road around is not easy to walk because it rained yesterday. Although it has been a long time, some places have not been done.

I had slippers several times in such a rapid running state, but fortunately my reaction was quite fast. Almost the moment the slippage occurred, I immediately stood firm on one side of my body.

My face looked a little ugly. Judging from my current progress, it may be difficult to arrive before the oxygen in the oxygen cylinder is exhausted.

I took a deep breath. When things got to this point, I could only try to enter the state of corpse.

The abilities of all parts of the body entering the petrified state will be greatly improved, including the same speed.

Moreover, under such a state, the consumption of human body in all aspects will be reduced to the extreme.

This way, the gas in the oxygen cylinder can last much longer.

In the following time, I quickly entered a state of corpse transformation. In this state, I could feel that the demand for oxygen in my lungs suddenly decreased a lot.

I said that I have returned to my senses. Entering this state is just a temporary solution. The side effects of such a state can be said to be very great.

Judging from the previous situation, we can clearly determine that there are indeed side effects in this state.

After entering this state for a long time, the feeling of the whole body will become quite dull in a short period of time after the state is removed.

However, there is no other way to do this in this situation, so you can only rely on this state to continue moving forward.

As oxygen continues to inhale, the whole person's perception becomes clearer and clearer, and both vision, hearing, and smell have returned to normal levels.

The surrounding scenes quickly retreated in my mind, and the more I moved forward, the more solemn my face became.

Things are not that simple, and it can be said that they are trapped in a very contradictory cycle at present.

There is no way to determine the specific direction of that thing now. If you are not wearing a mask, you can determine the general direction through your perception constantly disappearing. Only by moving forward little by little can you find the target I am looking for.

However, once the mask is taken off, you will probably lose all your perception in an instant and you will never be able to move forward.

As I moved forward, my eyes were also looking around. I couldn't miss a little something wrong. If I missed it, it would be difficult to find it.

You should know that the entire mountain is not small in size, and the culprit that caused us to fall into the disappearance of perception is still unknown.

If the culprit is not large in size, if you miss it, it is almost impossible to wait for the second opportunity to look for it.

Such a large mountain, and its specific location is so uncertain, even if you miss it, there is no way to know whether it was missed.

However, as I continued to move forward, the jungle continued to retreat, and gradually the trees around me became scarce. Suddenly, my intuition vaguely told me what was in front of me.

I calmed down slightly and immediately moved towards something I noticed was wrong.

After traveling through this woods, there was a clearing ground behind it. The moment I arrived at this clearing ground, I immediately smelled a bloody smell.

The blood scattered around the stars was unevenly distributed throughout the open space, and many corpses could be seen.

Whether it is the corpse or the blood on the ground, they were left behind not long ago. Judging by the colors and the condition of the corpse, it should not exceed 24 hours.

And between these corpses and blood, a black jar can be seen.

This black jar looks about 1.5 meters tall and is also very wide.
