With a loud trembling sound, the giant door slowly moved to the left with the center of the door as the axis, and gradually opened.

The strong breath of life spills into the corridor through the half-open and closed doorway, and wisps of light like fresh sunlight spread in. The three of them, who had not seen the natural halo for a long time, were delighted, and the warm light carried a strong earthy smell.

With such a strong breath of the living world, July speculated that it must be a derivative life behind the door.

The opening at the left end of the giant door turned 90 degrees, and it stayed firmly in the center, and a golden yellow halo came from behind the door, and the scene behind the door could not be seen clearly under the dazzling light.

The black-robed man and Ning Yun looked at July together, as the backbone of the three of them, July's opinions determined the direction of the team, and a series of crises were resolved one by one by this seemingly small girl, and July's position in their hearts was irreplaceable.

"Girl, look at it now." The black-robed man asked.

"Let's go over, I guessed right, this gate is the real passage out of Du Gate." July is still so elegant, replied with a smile.

Although July is young, he has a moderate demeanor and has never spoken in vain, the black-robed man nodded trustingly, and walked to the door with confidence and boldness, and his head would not be in the golden light, and he disappeared in front of the door in a blink of an eye.

"Girl, are you going to do it?" Seeing that July hadn't taken any steps yet, Ning Yun didn't dare to take a step.

July nodded Ning Yun's head, "Little thing, what do you want." Is that the kind of person I am? ”

As he spoke, he muttered to himself, "How good it would be if Tong Bingyang was still alive." "Looking at the remains of the red bulldog ants all over the ground, I feel sorry for the creatures of nature the most, not to mention these ancient species that are not easy to cultivate. How many Gu cultivation secret methods should be in the hands of a demon like Tong Bingyang, and these secret methods are unknown to modern people. Thinking that these secret techniques would be buried under the loess with this great ancestor, July felt a faint pain in his heart.

"What, Tong Bingyang? If that old monster is still alive, girl, then we'll be miserable. Ning Yun thought that the bunch of insects left behind after this person's death were so obedient, and it took a lot of effort to solve them, if he was still alive, he would still be able to do it.

Well, July beckoned Ning Yun to leave, "Hehe, I'm thinking too much." Let's get out of here. Otherwise, it's not good to have more variables. ”

There has always been a speculation in July as to why Tong Bingyang has mastered so many secret arts, and what he has seen alone is no longer something that a simple wizard can understand. What did he master, back then, even Miao Jiang's proudest Gu technique would be defeated by Tong Bingyang.

July's heart was directed to all kinds of connections, and she thought of that ancient book.

Could it be said that the Huangji Heavenly Book is hidden in the sand-buried ancient city?

Allowed by the pull of Ning Yun, July was pushed through the giant gate like a wooden man.

……

The world behind the door...... Suddenly, it is completely another cave, the sound of gurgling water slowly flowing from the heights, the crisp birdsong among the mountains, and all kinds of unique scenery in nature come together.

Pure white clouds drift through the sky from time to time, and the warm sunshine spreads across the mountains, reflecting on the rocks, and even the air is fresh as if it has been washed by rain.

"Wow!" On July's side, Ning Yun exclaimed. They stayed in the dark for so long that when they saw the blue sky and white clouds, they seemed particularly friendly and natural.

The affectionate breathe of the mountain air in July, revealing the quiet and leisurely appearance of her daughter's home.

They stood on one side of the mountain cliff, which was covered with crisp green grass and flowers and bones that swayed in the grass.

The black-robed man stood at the front of the cliff, a black robe rising in the wind, revealing a simple and cold atmosphere in the vicissitudes of life.

Soon, Ning Yun, who had calmed down, retracted his smile, his pupils suddenly contracted, and he said in surprise, "Impossible, how is this possible." She tugged July's cuffs and asked excitedly, "We are obviously hundreds of meters underground, how can it be a blue sky and white clouds behind the door." ”

July was the first to realize this common sense mistake, they went down from the waterway to the Sun Tomb with the hall, and then entered through the "Du Gate" in the Eight Gates, and the Yongdao walked in a straight line, without the slightest slope, that is, even if they were not walking down all the time, they were walking on the straight road. They didn't even walk on the ground, and the sight in front of them inadvertently slapped them in the face.

"It's on the ground!" July also frowned, and then looked at the clouds in the distant sky, no matter how you look at it, it doesn't feel too real, and secretly wonders if it is an illusion created by Tong Bingyang in an unknown way?

Taking a little more breath, July found more problems, the oxygen content in the air was not right, "how is the oxygen content of this world a little ......"

"Isn't it too high?" Not only is the oxygen content wrong, just by taking a breath, you should know, that feeling of sudden clarity, I am afraid that the oxygen content is as high as 9 percent or more, the man in black robe said with the two of them behind his back.

Well, July agreed. It is unlikely that such a large-scale illusion would be created. It would be frightening to say that all of this is true.

"The ancient city is buried in sand, since it is buried in sand, shouldn't it be underground?" Ning Yun inquired towards the back, and the doubt in his heart suppressed himself. She also feels the same way as July, where the brilliant and diverse colors in the space are no longer so real.

"I don't know, the ancient city buried in the sand is a very vague concept. No one said it had to be built underground. "In ancient times, there may have been different interpretations of the same word, and the black-robed man himself could not answer it.

Since she couldn't figure it out, Ning Yun didn't want to think about it anymore, she was such a creature who didn't want to waste brain cells, her belly gurgled a few times, and her eyes looked around dexterously, "It doesn't matter if it's really fake, this mountain of birds can't be fake." Ning Yun is not a vegetarian, hearing the sound of birds is like hearing the bell of the meal, and he is thinking about how to catch something flying in the sky to fill his stomach.

At this time, July turned around, and the huge door opening behind him had disappeared silently, and there was no crack in the door, as if it had never appeared there, and behind him was just a small path down the mountain.

"Cloud !!"

"Yes, girl. What's up? ”

July said angrily, "Can you find me some vegetables, you know, I don't eat meat." As soon as she heard that she was going to catch birds to eat, July was inexplicably worried.

"Well, girl, you eat grass. I'm the worst. In these barren mountains and mountains, there should always be fruits, vegetables, and so on. I'll look for it. Ning Yunjiao smiled and ran away. Walk quickly down the cliff along the sheep intestine mountain road.
