Chapter 213

Xiao Yun and Xiao Zi were shocked when they heard this.

The secret treasure was actually built by the dragon family. Doesn't that mean it used to be the nest of the dragon family?

No wonder the animals here are so big. Is this the world of dragons? "But not long ago, I found a document, which records that the only secret to open the secret treasure is the blood of the dragon family. It took me three years to finally find a sword beast. This sword beast mated with a dragon a long time ago, and its eggs have experienced a lot

It took hundreds of thousands of years to hatch. The little sword beast hatched really has a strong dragon blood. "

The dark spirit looked at the little sword beast and said.

"Do you want to use it to open the door of the secret treasure?"

Xiao Yun was surprised.

He had always thought that after entering the door, it was a secret treasure, and the treasure in it was waiting for him to compete. However, it is totally unexpected that there is a treasure hidden in the secret treasure. That treasure is the real secret treasure of the dragon family!

The so-called secret treasure world is actually a dragon's nest.

"That's right!"

Dark spirit nodded, "many people spend their whole life studying this secret treasure. Now, I finally found a clue. How can I miss this opportunity?"

Xiao Yun pondered for a while and thought it was reasonable. In fact, he also wanted to find out. What is the so-called secret treasure? Why attracted so many people to take risks one after another.

"Haw!"

Little purple frowned and cried twice. Her fierce eyes looked at dark spirit and looked like she wanted to protect the little sword beast.

The little sword beast trembled and hid behind Xiao Zi.

"Little guy, you don't have to worry. I just use it to open the secret treasure and won't kill it."

Said the dark spirit.

"Haw!"

Xiao Zi looked at dark spirit with suspicious eyes. Some didn't believe, some doubted and some cautious.

"Xiao Zi, trust her once."

Xiao Yun winked at Xiao Zi.

"Haw!"

Xiao Zi raised her head and looked at Xiao Yun. She meant that she would take care of the little sword beast.

"Good!"

Xiao Yun has no problem.

Then he looked at the dark spirit and said, "when shall we start?"

"Now!"

Dark spirit can't wait to get up.

"Good!"

Xiao Yun immediately turned around and was about to leave.

However, the moment he turned around, the dark mountain in front of him suddenly raised a dark thick fog. The thick fog became bigger and bigger, and directly swallowed up and covered his sight.

"This is..."

Xiao Yun stepped back.

"Where is this?"

Dark spirit suddenly felt a bad premonition.

"I don't know. In order to escape the pursuit of the sword beast, I took you into a black mountain."

Xiao Yun explained.

"Montenegro? Are the trees and rocks black here?"

Dark spirit asked sharply.

"That's right!"

Xiao Yun turned to look at dark spirit.

"Heifeng collar, are we here?"

The dark spirit's face turned pale for a moment. "Quickly, put the fire at the entrance. We can't let the black fog come in, otherwise we'll die."

"What is black wind collar?"

Xiao Yun asked as he did.

"There is a terrible monster in Heifeng collar. This monster is one of the strongest monsters in the secret treasure world. We call this monster black mountain old demon."

The dark spirit explained, "the reason why the trees, soil and rocks you see are black is that after blood dyed the ground, trees and rocks red, they became black after countless years of breeding."

“……”

Xiao Yun was surprised.

He had never seen anything dyed red by blood, but it was the first time he had heard that blood dyed things black.

It is said that to dye black things with blood requires not only a lot of blood, but also the invasion of time and years. Even in the invasion of years, blood should be covered every day.

"What kind of monster is the black mountain old demon?"

Xiao Yun asked after burning the hole.

"I don't know, because those who have seen the black mountain old demon are dead."

The dark spirit was very afraid.

Those who have no intention of breaking into this territory have never lived, and no one has ever been out alive.

"Snap!"

Just as the words of the dark spirit had just come here, suddenly something rushed in from the outside and put out the flame directly.

"Shua!"

Then, a black root strip swept into the cave. After drilling in, it quickly tied to Xiao Yun.

"Hum!"

With a wave of Xiao Yun's hand, a sense of sword broke out.

"Poof!"

The roots are cut directly to pieces.

"Boom!"

As soon as the tree root was destroyed, the ground of the cave suddenly cracked, and a tree root the size of a human body came out and pumped it towards Xiao Yun.

"Buzz!"

Xiao Yun was in control of the sword. As soon as the intention broke out, the huge tree root was severely pulled onto Xiao Yun. The tree root was twisted to pieces, but Xiao Yun pulled it out of the cave.

"Haw!"

"Help me..."

"Wow!"

The moment Xiao Yun was pulled out of the cave, he heard the screams of Xiao Zi, dark spirit and little sword beast from the cave.

"Asshole..."

Xiao Yun roared, grabbed the giant in his hand and rushed towards the cave.

However, after he approached, he found that there were huge tree roots everywhere in front of him, like a startling python, and there were such tree roots everywhere in all directions.

"Buzz!"

As soon as Xiao Yun approached, a tree root suddenly pulled over.

"Break it for me!"

Xiao Yun's sword intention erupted along the giant, and the terrible destructive force went straight up.

"Boom!"

The huge tree roots were cut off one by one, but the more he cut, the more and more tree roots attacked, and the closer the tree roots were to Xiao Yun.

"Fire? Yes, it's fire!"

This is the root of the tree. Since it is a tree, it is afraid of fire.

No wonder the dark spirit asked him to set fire at the mouth of the cave. That's the idea.

Sword potential——

Xiao Yun shouted angrily, and a terrible sword potential gathered on the giant engine in his hand. As soon as the sword potential appeared, the ghost fire burned.

"Boom!"

The sword posture carried the ghost fire to the tree root, and soon the tree root burned.

"Roar..."

A roar sounded from the ground, and the roots were quickly taken away.

"Want to run? Which is so easy..."

Xiao Yun shouted angrily, and the giant engine in his hand inserted into the ground. I saw that the ghost fire flowed around like water.

In the nether world, all the things touched by ghost fire, whether the roots or the surrounding trees, burned.

"Roar!"

After a large area of ghost fire burned, the tree roots disappeared, together with the dark fog. In front of us was a sea of fire.

"Damn it!" when Xiao Yun looked at the cave, there was no cave there, not even a mountain.
