Following the three extraordinary masters of Xuanbing Pterosaur flying over the ancient continent, Yang Xiao truly felt the vastness of the ancient continent.
Before this, because he was worried about the attack of super powerful monsters in the ancient continent, Yang Xiao usually flew on the edge and did not go deep into the hinterland.
The three extraordinary warriors of Xuanbing Pterosaur have powerful deterrence in the ancient continent. As long as the three of them fly over, the coercion will spread instantly, and the nearby monsters will immediately stop their activities and hide quietly in their respective territories. .
Occasionally, you can hear a few roars in the distance. The third child of the Black Ice Winged Dragon told Yang Xiao that those were the roars of some extraordinary monsters who were also in the holy supreme realm. Even with the power of the Black Ice Winged Dragon, it was impossible to hear it. After hearing those roars, they will not easily violate their boundaries.
Every powerful monster has its own territory, especially the super powerful monsters above the imperial level. Their territory is not allowed to be invaded.
And when it comes to the Saint-level Supreme, it is even more of a terrifying existence.
In about half an hour, the Xuanbing Pterosaur boss crossed a majestic mountain and flew towards a valley.
"Ahead is the Shenlong Ruins Valley."
The third child said beside Yang Xiao.
Yang Xiao looked from mid-air, and the valley in the distance looked very abrupt.
The surroundings are lush and green, but this valley is burnt yellow and black, as if it is a desert in an oasis, and it seems as if it has been burned by fire.
Yang Xiao made a visual inspection and found that the valley was quite large. Viewed from mid-air, the length and width were over a hundred kilometers.
The boss of Xuanbing Pterosaur slowed down and slowly arrived above a lake in the valley.
Then landed at the lake.
Yang Xiao stood by the lake and looked around, feeling a strange feeling.
Ever since Yang Xiao entered the ancient continent several times, he had the impression that the ancient continent was full of high mountains and ancient forests, accompanied by all kinds of monsters.
However, in the huge valley in front of us, there was no green at all, not a tree or a blade of grass, and the whole body was covered with charred rocky ground, not a single blade of grass growing.
The lake in the valley covers an area of at least 20 to 30 square kilometers. The surface of the lake is calm and there is no sign of fish activity. Standing by the lake, Yang Xiao found that the water is crystal clear and he can directly see the lake five to six meters below. , not to mention not seeing the swimming fish, not even the insects and microorganisms.
This is a "dead lake".
Seeing Yang Xiao's expression, the Xuanbing Winged Dragon boss laughed and said:
"Yang Xiao, do you think this valley is weird? Is it incompatible with the surrounding environment?"
"Well, it is true that the rest of the ancient continent is full of life, but this valley is lifeless and lifeless. Why is this?"
Even in the desert with the harshest environment on earth, there are still some animals living in it. There is such a large lake in this valley, surrounded by ancient forests, but it is not a condition for the survival of life. Why is this happening?
"We are also very confused. I remember this valley has always been like this since I first came here when I was a child. My father and grandfather told me that it has been like this since they came here. It is said that it has been like this for thousands of years, maybe This was how it was here tens of thousands of years ago.”
"Brother, where is the mysterious cave you mentioned? Where is it?"
The third child was a little impatient and looked at the elder brother.
The boss laughed,
"Third brother, you are just impatient. This is Yang Xiao's first time here. Shouldn't I introduce it to him and let him get familiar with the environment here?"
"Let's go take a look at the cave first. Brother Yang will come out later to get familiar with it."
The third monkey said anxiously.
The boss smiled and shook his head and walked forward.
There is a black mountain in the middle of the valley, about three to four hundred meters high and more than ten kilometers long and wide.
"Brother, the mysterious cave you mentioned is not the Black Mountain, right?"
The third child said.
In his memory, he always called this mountain Black Mountain. It was also the only strange mountain in the ancient continent that did not grow grass or trees.
Yang Xiao walked to the Black Mountain rock wall and saw that the rock wall had the sheen of fish scales, as if it were a crystal.
I touched it with my hand and found it was cold to the touch.
What kind of ore is this?
According to the knowledge Yang Xiao received on Earth before, these black rocks are a bit weird. The entire valley is barren of grass, no mosquitoes, and no monsters. It is most likely related to these black rocks.
An idea suddenly popped into Yang Xiao's mind.
Are these radioactive rocks?
Then he rejected this idea. On the earth, there are also radioactive areas caused by nuclear wars and nuclear power plant accidents. There is also life in those areas, and the vegetation and animals will mutate and become abnormally strong.
Radioactivity is not a simple explanation for the lack of life in this valley.
"Boss, where is the mysterious cave?"
The third child urged. He was familiar with this valley. He had been here several times, but there was nothing interesting here, so he didn’t pay much attention to it. Now he suddenly heard that there was a mysterious cave here, and it was also related to the legendary Brother Shenlong. , how could he not be curious and impatient?
The boss of Xuanbing Pterosaur, on the other hand, took his time and walked along the foot of Black Mountain for about a thousand meters and stopped in front of a mountain that looked like it was cut by a knife.
The boss of Xuanbing Pterosaur pointed at a mountain rock five to six meters high and seven to eight meters wide, as if cut with a knife, and said:
"Look, what's different here?"
The second and third children took a look and said:
"What's unusual about this? Such large rocks can be seen everywhere in Montenegro."
"There's nothing unusual about the appearance. Is this the mysterious cave you mentioned?"
The two brothers expressed doubts.
The Xuanbing Winged Dragon boss looked at Yang Xiao.
Yang Xiao said:
"If there is anything unusual, even if this cross-section is too regular, there are all kinds of big black stones all over the mountain, many of them have flat surfaces like Duxiang, but their shapes are not regular. Only here, the length and width are They are all regular and neat, and although they are integrated with the entire mountain, if you look carefully, there are traces of processing and transformation.”
It is normal to have a flat section on the mountain, but such a regular section must have been artificially modified. This is Yang Xiao's common sense.
When Yang Xiao said this, the second and third Xuanbing Winged Dragon also thought it made sense. He looked at it carefully, knocked it with his hand, and asked:
"Brother, is this the door to the mysterious cave?"
The boss laughed and said:
"Yang Xiao has good observation skills. Yes, this is the door to the mysterious cave."
"How to open it? Brother, please stop being too tight-lipped and hurry up. You know that I am impatient, brother."
The third child was anxious and looked at the elder brother pleadingly.
The boss smiled and said:
"Now that you know this is the door, why don't you try to open it?"
The third child rolled his eyes and said:
"Brother, this is what you said."
After the third child finished speaking, he put his hands on the stone door and shouted:
"open!"
"Buzz!"
There was a vibration, and small stones rolled down from the mountain above the Shimen, but the Shimen did not move at all.
The third child looked back at his elder brother and saw that he was smiling without saying a word, and said,
"Brother, I will use my full strength."
After saying that, he exerted force with his hands, and a surging force surged out like a river.
This time, the nearby mountain trembled slightly, and a few black stones rolled down the mountain. However, the door remained unopened and almost motionless.
Lao San worked hard, and with his upgraded supreme cultivation level, he could even destroy a hill, but he couldn't deal with this stone gate?
"I'm so angry, ah!"
Lao San went out with all his strength, and the mountain trembled again, and dozens of black stones rolled down from above. However, the huge stone gate still did not waver at all.
The third child stopped, his face flushed, and turned to look at the elder brother.
The eldest brother still smiled and said nothing, as if to say, "You can do whatever you want, if you have the ability to open the stone door."
The third child got angry, took a few steps back, shouted loudly, and punched the stone door.
When I pushed the stone door hard before, I used dark energy. This time, when I punched it away, I used my magical power.
A single blow from a saint-level supreme superpower can directly flatten a hill and create a hundred-meter-deep crater in the hard granite mountain. No matter how strong this stone door is, it cannot withstand Lao San's punch.
"boom!"
There was a loud noise, the mountain shook, gravel flew up, and dust flew everywhere.
At the same time, a rune flashed on the stone door, and Lao San felt his body shake, and was pushed back tens of meters by a powerful reaction force.
