"Old sir, who are you?" Lu Feng'er asked at the old man in front of him. Although the old man seemed to have no airs, his demeanor was quite extraordinary, so he always felt that this old man was quite big.

"Hey, it's just a little old man, don't be so polite." The old man waved his hand and said, "Just call me old man!" The old man should have considered that it is inconvenient for Lu Fenger to call him.

"How did that happen?" Lu Feng'er shook her head repeatedly.

"You can do whatever you ask you to do. Where can you get so much nonsense?" Seeing Lu Fenger's squeezing look like Niu Niu Niu, the old man seemed to have a little temper, so Lu Fenger could only agree with a wry smile.

"If you want to go up and have a look, come with me." The old man said to Lu Feng'er and left on his own. Seeing this, Lu Feng'er immediately followed.

"Hmm? Lift?" Lu Feng'er was also shocked by the thing in front of her. "Is there such a thing actually in the prehistoric era?"

"You stupid guy, this is just built now." The old man gave Lu Feng'er a blank look, which made Lu Feng'er look embarrassed. The old man ignored him and took him to the elevator and quickly pressed the button.

The sound of the lift running was really bad, and the shaking appearance made Lu Fenger feel uncomfortable, for fear that it would fall.

"This thing is very convenient to operate, but after all, the temperature here is too low, so there is no way to ask for too much, just not falling off. This is guaranteed." The old man looked at Lu Feng'er holding the railing and looking out with his eyes straight out.

The elevator was getting higher and higher. Not long after, Lu Feng'er felt a hazy feeling in front of her eyes, and a biting cold feeling came from her face.

"Now we are in a cloud," the old man seemed to be treating himself as a tour guide. "The temperature here shouldn't be clouds, but the magical thing is that even if the water vaporizes into ice crystals, they can still float in the air. Generally speaking, this mass should have fallen on the ground long ago, which is one of the major puzzles here."

"Then is this a supernatural phenomenon?" Lu Feng'er felt aroused. After all, the more unscientific it is, the more it can prove that he was the reincarnation of an ancient powerful man. This is not an ordinary place.

"Supernatural phenomenon? Yes!" The old man was stunned and nodded affirmatively. "It seems that you are not too stupid either." Hearing this, Lu Feng'er couldn't help rolling her eyes to the old man, but she felt powerless to refute what he said.

With a 'clang', Lu Fenger and the old man arrived at the top of the Great Wall. Although they could not see clearly from the bottom, they found that the places that have been developed are now visible.

The town at my feet is so small, with a small house in groups of three or three located in it, with a winding path in the middle and well connected. There is an open space in the center, and there are two huge stone pillars of varying lengths during this period. Next to the stone pillars, there is an arc stone broken into two sections. Therefore, Lu Feng'er guessed that there should have been an arch here.

Going forward is the inspection station where Lu Fenger just came. Now this is the largest and most complete building here. The iron hut behind the inspection station is the temporary laboratory.

When I walked to the other side, I saw that although the scenery in front of me was monotonous, Lu Feng'er's heart suddenly twitched. After tens of millions of years, the unknown forest still stood proudly on the snow field, ranging from dozens of meters to about two or three hundred meters high, and was on standby at any time like a soldier.

The trunks of the tree are even harder than iron and emit cold light against the backdrop of the white snow. The leaves are not thick and lush, but they are as creepy as if they are born as a sharp sword.

Even further away, it was covered with a thick layer of snow, but the sign of mud and stone collapse also showed that a large avalanche occurred there, but surprisingly, none of the trees fell to the ground and were firmly rooted in the land.

"Why, I was frightened?" The old man next to him sat on the ground, took out a pot of wine from somewhere, and drank it on his own, "No, do you want it?" As if he suddenly thought of Lu Feng'er next to him, he handed him the bottle.

"No, this is really not needed!" Lu Feng'er stopped repeatedly.

"That's right, you're still a little brat, what wine do you drink!" The old man muttered, rolling his eyes so much that he was so angry that he rolled his eyes.

"Old man, you said opposite - I said the forest on the other side is of research value?" Lu Feng'er swallowed.

"Nonsense, I've wanted to study it for a long time, but why haven't you been there yet... You can tell if you take a step forward and look down." The old man showed an indescribable smile.

Lu Feng'er did as he did.

"Roll" but then he suddenly took several steps and sat on the ground.

"I forgot to tell you, take it slowly, don't be so anxious!" The old man was very happy when he saw his prank succeed. At this moment, Lu Feng'er was also scared and ignored his words.

After he took a breath, he slowly got up and moved over, stretched his head with difficulty, and looked down.

If I saw the Great Wall over there before, if it was a general wearing hard armor, the Great Wall here would be a soldier who was torn off all his flesh and blood but was unyielding. From the top to the bottom, there were almost no places that were complete and flat. The deep pits on the surface should be the scratches left by the sharp knife of the cannon marks and the steel claws.

The Great Wall over there was dark and shiny, while the Great Wall over here was stained with blood and was covered with redness, like a resentful spirit, with a trace of bone-transparent cold and evil intention. Today, millions of years later, it also disturbed his mind.

What's even more terrifying is that a crack is not considered a deep pit, like an abyss, hidden in a place that cannot be seen before. It is long and thick. At first glance, it is dark, only darkness, as if the whole person and his soul are about to be swallowed up.

Lu Feng'er took a look at her for a while and felt that her soul was about to leave her body and was sucked away and swallowed, unable to resist.

"Ba", the old man patted Lu Feng'er hard on the shoulder, and Lu Feng'er was so scared that she almost jumped up.

"Thank you!" Lu Feng'er recovered and panted and thanked the old man. "I almost felt like I was going to die."

"Normal, when I saw it, I was stunned for three days, and some even worse, I fainted directly. You are fine." The old man pursed his lips, "Now I know why we can't go to the opposite side, right?"

"Yeah!" Lu Feng'er slowly came to her senses. 'Damn it, my chance wouldn't be in that pit, right? Is this really going to die!' Lu Feng'er couldn't help but feel weak when she thought of this.

"By the way, the old lady Wang said that you found something black, it seems to be very powerful?" The old man suddenly asked while sitting cross-legged on the ground to rest, as if he was interested in it.

"Well? Old man, do you know who I am?" Lu Feng'er said in surprise.

"Tell the point, don't talk nonsense." The old man said impatiently.

"Uh, this is the thing..." Lu Feng'er told the old man in front of him carefully what he saw and heard. The old man put away his cynical appearance before and listened carefully, for fear of missing a word.

"Is this really a big discovery?" After hearing this, the old man swears excitedly, "Look at the deep pits on the Great Wall, can they be corroded by that black energy?" The old man asked Lu Feng'er again.

"Uh? No, this thing seems to be spreading all the time." Speaking of this, Lu Feng'er's back was sweating heavily. The Great Wall was pitch black. Where can I tell where I was infected and where I was not infected?

"Didn't it mean its energy has a limit?" The old man didn't plan to give up his guess so easily.

"Uh, then..." Lu Feng'er didn't know how to answer.

"Forget it, I'll go down and take a look." The old man jumped up with a swoosh, and it was impossible to tell that he was an old man over 60 years old. "Do you want to go down together too?" He looked at Lu Feng'er.

"Me? I plan to be here..." Lu Feng'er just spoke,

"I'm the only one left." Suddenly, Lu Feng'er heard this voice again. The sound now seemed not on the Great Wall but from...west?
