Zhang Qiang didn't understand what I was doing this for, and looked at me with a puzzled expression.

I gestured to the zombie below, then made a silent gesture.

Zhang Qiang looked down again, and finally understood what I meant.

Because, those zombies, after we spoke, became a little manic.

Uh-uh-uh......

Whoop......

Those zombies, constantly looking back and forth, left and right, seemed to be looking for our traces.

'Don't talk!!' I mouthed Zhang Qiang and said silently.

Zhang Qiang immediately understood what I meant, so he nodded.

When I saw this, I let go of the hand that was covering his mouth.

After glancing at Zhang Qiang and Liu Gouyu, I pointed ahead and motioned for us to get out of here quickly.

They immediately nodded.

Now, we don't dare to delay any longer.

Walk as fast as you can without making a sound.

Continue up the hill towards the top of the slope.

Although we were very careful along the way, we sometimes let some of the rocks and snow fall underneath.

The results can be imagined......

The moment they heard the movement, the zombies on the mountain road below immediately looked around, and at the same time, a series of unknown roars came out of their throats.

I was taken aback and quickly stopped.

After a while, the zombies finally quieted down.

We breathed a sigh of relief and continued to walk diagonally upward.

We saw many jaw-dropping images along the way.

For example, a group of zombies are constantly gnawing around an animal, although we can't tell what kind of animal it is.

But that's not even the most surprising.

As we walked on, we were shocked to find that some zombies would eat their companions without food.

The expressions of the three of us changed slightly, and we all looked at each other, and we both saw fear in each other's eyes.

Could it be that these zombies have mutated again?

Before, whether in the Forest of No Return or in the Desert of Regret, we have never seen zombies eating their own kind.

I quickly retracted my thoughts, winked at them, and motioned for us to move on.

And just like that, the three of us walked up the hill.

After more than an hour, we finally made our way to the back of the snow-capped mountains.

I looked down and saw that there were a lot fewer zombies on the mountain road now.

Thinking of this, I looked up again at the top of the snow-capped mountain.

It looks like we should be very close to our destination.

"This is probably near the underground castle. But...... Where is the entrance to the underground castle that Collier is talking about? I frowned slightly and said to myself.

As I whispered, a group of mercenaries suddenly approached the mountain path below.

Zhang Qiang was startled, quickly patted me on the shoulder, and then pointed to the position on the left side below.

When I saw this, I immediately fell silent, and my eyes followed the position of Zhang Qiang's finger.

Really!!

There really was a group of mercenaries walking from the left to the right.

The three of us looked at each other.

It seems that my guess was correct!

The entrance to the underground castle should be nearby.

Or maybe, this group of mercenaries is planning to go to the underground castle?!

I kept thinking about it.

However, in the next second, a few of us saw an even more shocking scene.

Less than two seconds after the group of mercenaries appeared, a group of men dressed in the uniforms of the research institute defense team also walked to the right.

From our point of view, they must have known each other's existence.

After learning of each other's existence, the two sides did not fail to attack each other.

There is only one answer - they are allies!!

Zhang Qiang was obviously shocked when he saw this scene.

Judging from the information we have received before, the caravan, the scientific research institute, and the mercenaries should be in a three-legged relationship, and even at some times, they are still in a state of hostility or confrontation.

Now, however, we find that the armed forces of both sides are in the same place.

What the hell is going on???

My eyes kept jumping, and I only felt that many of my previous inferences seemed to be overturned at this moment.

It took several deep breaths before I forced myself to calm down.

"Leave nothing else at that. Finding the entrance to the underground castle is the key! I whispered, both to myself and to the other two.

As I spoke, my eyes remained fixed on the two groups of armed men.

They did walk to the right.

Could it be ......

Is the entrance over there?

After thinking about it, I decided to follow along.

Beckoning to the two behind me, I quickly walked around from above.

After walking about fifty or sixty meters, I stopped.

Because the mercenaries and members of the scientific defense team below also stopped.

After about a dozen seconds, they returned to the same way they came.

Of course, there are still a few zombies roaming around.

However, it is still the same as what we found before.

Those zombies don't seem to attack mercenaries at all, and certainly don't attack the defense team.

All of this, what the hell is going on??

I stood quietly on the hillside, looking down at their patrols.

After a few back and forth, I had a rough idea of their patterns.

"These mercenaries and members of the Commissariat were on patrol every four minutes, walking from the left side to our feet, staying where they were for fourteen seconds, and then heading back the way they came. There were only about five or six zombies roaming around directly below us, and the three of us should be able to kill them. I quickly told the two people behind me what I had observed.

"The entrance to the underground castle ......," Liu Gouyu looked at me with some hesitation.

Zhang Qiang glanced at him angrily: "You haven't guessed yet??" I don't know what to do! The mercenaries and members of the KDF have been below us several times. In other words, the entrance to the underground castle is likely to be at our feet, and we only need to find a way to go down for a while, and we should be able to find the entrance!! ”

Liu Gouyu showed a suddenly realized expression: "So that's the case, so you guys were just looking at the law of their patrol??" ”

"What if it weren't?" Zhang Qiang glanced at Liu Gouyu and sighed.

Seeing that he still wanted to say something, I quickly interrupted: "Okay, don't talk about this yet. In two minutes, we'll go down from the left. There's a boulder right down there, so we can hide behind it. After the mercenaries and the members of the scientific defense team left, we will kill the zombies. This way you can enter the underground castle!! ”
