Before reaching the end of the ancient mountain range, Lin Feng thought more than once, what is the end, endless ancient buildings, or abyss?

Or is it still endless jungle mountains?

However, when it was really close to the end, Lin Feng found out that he was wrong. What appeared in front of him was a tall city wall.

It is so tall that it can stand tall and stand tall, and cast a large shadow. It is not known how long it is. Even if it is far away, its outline can still be seen vaguely.

Lin Feng and Ji Yuxuan looked at each other, remembering the scene they had seen while standing on the top of the mountain two days ago. Perhaps the blue-black outline they saw at that time was the city wall, not the mountains and rivers they thought.

Such a city wall, I don't know what material it was cast, showing a deep blue-black color. After approaching, one can clearly feel a deep and cold atmosphere. That kind of breath seems to permeate into the human body and be carved into the human bone.

Ji Yuxuan couldn't help but shivered, tightened her clothes, and whispered to Lin Feng: "I feel the yin..."

Lin Feng's face was solemn, and he nodded slightly: "I feel it too!"

I don't know the ancient city that has existed in the world for thousands of years. It is silent, like it comes from the legendary underworld region, without any breath of life, but stands silently at the end of the world.

Is this the main area of ​​the ruins?

Lin Feng was suspicious. He and Ji Yuxuan did not choose to soar into the sky and directly crossed the city wall. Instead, they walked down the city wall to see if they could find the city gate.

Such a city wall, built so majestic, must be engraved with countless array patterns, and there must be array patterns in the forbidden air domain.

The endless years passed, Lin Feng didn't know whether those formation patterns were still in effect.

When you are in the ancient mountains, although most of the time it is quiet, the roar of the ancient beasts will sound from time to time. But here is different, everything is quiet, and people's heartbeats can almost be heard.

Around the city wall, a few small trees occasionally appear.

Lin Feng was amazed. Why didn't those ancient beasts come here? Did they perceive danger? Or is it because this was a place where humans lived in the past, and there was something inscribed in their bones, that they didn't dare and didn't want to come?

Lin Feng didn't know.

After walking eastward for more than half an hour, he and Ji Yuxuan finally saw the gate. It was not intact. The gate made of some kind of metal was more than a thousand meters high. The whole body was twisted and twisted, and it seemed to be violently bombarded. After that, Lin Feng noticed that it was half open in the middle of the door, and there was a fist mark sunken in on it.

I don't know how much time has passed since that fist print, but looking at it at this time, it still made Lin Feng breathe faster, and felt dizzy for a while.

"This is the power that transcends the sacredness..." Lin Feng had a clear understanding in his heart. He dared not look any more, and quickly withdrew his gaze.

But in my heart, it was shocked inexplicably.

Is the power of the immortal old monster? In the past, he had heard about it, but it was the first time he saw it.

Even if countless years have passed, the traces of fist intent left on that fist mark still make the scalp numb.

The door was opened by an old immortal monster, and there was a huge gap. The mottled gate was full of rust stains, and many places were even decayed, completely rusted through, showing a black-green color, which seemed to be scattered when touched.

In the crack of the door, a faint gray-black mist floated out. It was too light and almost undetectable, but it was endless, and I don't know how many thoughts floated.

That is death, yin, evil...
