Behind the hillside where Wu Yi came, he listened carefully, but he didn't hear the sound of the calf here. But even so, Wu Yi didn't feel that he had lost it.

Instead, calm down and carefully observe the surrounding environment, in fact, with the size of this fox hunting fox larger than a cow, there will definitely be traces left between walking.

And the bigger the body, the greater the traces left, and finally Wu Yi saw some broken branches between two dense trees.

Moreover, on the ground between the two trees, there were also some traces of trampling, and the animals that could cause such traces should be not small, so Wu Yi quietly walked behind the trees.

The calf was silent, and Wu Yi's first thought might be that the calf was killed, but if you think about it carefully, there is a problem, if it is just to kill and eat, why not kill it first and come back in your mouth.

Along the way, the calf barked and struggled, which especially affected the hiding of the fox, and since it had spent so much effort, it was definitely not to kill and eat it directly.

People's curiosity is very powerful, and since they can't figure it out, they have to go and check it. Wu Yi walked behind the two trees with traces.

I found that behind the tree, there was a boulder 2 people high, and this boulder was actually a rare oval shape. Such a boulder should have appeared in the middle of a river, but it appeared here suddenly, because there was no river in the vicinity.

There must be a demon when something goes wrong, Wu Yi went up, checked, put his hand on this boulder, but let it go, Wu Yi was not prepared for a while, and staggered in the direction of the stone.

After standing firmly, he found that half of his arm was actually inserted in the boulder, Wu Yi was nervous, and felt his hand retracted, but found that his hand couldn't move.

But Wu Yi took a step forward, stretched his hand into the stone again, and actually went into the stone a little more.

At this point, Wu Yi has already reacted, this boulder can only advance, not retreat. Until now, Wu Yi began to hesitate, whether to advance or retreat.

In fact, Wu Yi already had the answer in his heart, if he couldn't retreat, he couldn't cut off his arm.

Then there is only a way to go in and take a look, Wu Yi is worried about what kind of scene he will see after entering, human beings will always be afraid of the unknown.

After a person hesitates, if he does not make a quick decision, then he will look left and right and hesitate all the time.

So when Wu Yi found that he was hesitating, he immediately made a decision and rushed towards the boulder.

When rushing into the boulder, Wu Yi seemed to have rushed into a small layer of water, and in half a second, Wu Yi passed through this layer of barrier with slight resistance.

Wu Yi passed through with his eyes closed, and the resistance of his body had already told Wu Yi that he had passed through, and immediately stopped moving forward.

However, it is also fortunate that Wu Yi stopped in time, because the front of Wu Yi is not flat, but a slope, extending downward, with no end in sight.

After coming in, Wu Yi still didn't hear the sound of the calf. However, Wu Yi had already found the footprints of the fox hunter from the ground.

This shows that he is not on the wrong path. It stands to reason that in such a hole, it should be pitch black, and there is no way to see the road.

Wu Yi turned around, only to find that his rear was actually transparent, that is, the outside could not see the inside, but the inside could see the outside.

The moon was shining high, and the moonlight was shining through the cracks in the trees into this strange hole. Wu Yi stepped on the moonlight and walked towards the cave.
