The more this happens, the more the ancient demon soul wants to destroy Yin Dong. As for the previous idea of ​​taking over Qiu Ying, he threw it to Java.

The demonic energy that rushed out of the cracks in the riverbed became even more surging, and the entire riverbed also vibrated violently. A large area of ​​rocks hit Yin Dong again.

Rumble...

The huge wave of demonic energy was roaring with countless dancing huge rocks. The ancient demon souls deep in the riverbed could foresee the explosion of Yin Dong's body, and laughed loudly.

The next second, the ancient demon soul was stunned.

The black air wave with countless stones hit Yin Dong's side, and was pulled into it by the vortex surrounding him, becoming part of the vortex, and was swallowed and refined by him.

The dozens of meters of radius centered on Yindong formed a stable rotating black vortex, with countless stones rising and falling in it, and soon they were decomposed into powder.

The black sword is suspended in the vortex of demonic energy, devouring demonic energy. Moreover, the black sword is not like Yin Dong, which is disturbed by magnetic fields, but has gains. The efficiency of devouring demonic energy is faster than Yin Dong.

For a moment, the inside and outside of the vortex seemed to have its own space.

The ancient demon soul under the riverbed roared incredibly: "How could this human cub be so strong?"

Yin Dong sensed the waves of the demon soul under the riverbed, which happened to be within the area covered by the formation. He was not in a hurry to open the formation, and continued to carve the formation dust and expand the area covered by the formation.

The ancient demon soul under the riverbed was tossing for a while, and found that the impact of the demonic energy shock wave and the huge rock had no effect on Yin Dong, so he was too lazy to tossing again.

"If it weren't for the Demon-Capture Monument suppression, why would this Demon Ancestor be humiliated by such an ant-like thing? It's so hateful!"

The ancient demon soul looked at the deep center of the earth, and was suppressed by the demon sealing monument, so depressed that he wanted to hit the stone and die.

Bang--

A stone fell from the crack above and just hit the head of the ancient demon soul. However, he had no entity. The stone passed through the demon soul, smashed on the demon sealing monument, and fell on the head of his body.

"It's outrageous! The human clan, I am a demon ancestor who is irreconcilable with you!"

The ancient demon soul was extremely angry and claimed another black account for Yin Dong.

Yin Dong, who was innocently caught in the attack, didn’t know, and he knew... he didn’t care!

The stone just now was hit by the black sword. There were dry blood stains on the stone, and the blood stains emitted a breath that made the sword spirit Xiao Hei tremble and disgusted.

The sword spirit Xiao Hei was completely instinctive. When the stone rushed up from the depths of the earth and was swept into the vortex around Yin Dong, the black sword flew out, and he was so desperate that he just followed a crack that reached the center of the earth and smashed on the body of the ancient demon soul.

At this time, Yin Dong felt that the area covered by the formation was almost the same, so he opened the formation. A translucent formation barrier flashed out, and the energy brilliance of the demonic energy and the blue crystal were flowing on the formation defense cover.

"The damn human cub is actually setting up a formation? Why did he set up a formation in vain..."

The ancient demon soul roared deep in the center of the earth, looking up incredibly, and could sense the power of the formation to extend in all directions and reach the center of the earth.

The original body was suppressed by the demon sealing monument, and the ancient demon soul could not escape from this area, which means that he could not escape from the formation area!

This array cannot devour the demon soul... right?

At this time, the ancient demon soul was panicked, and an invisible crisis emerged, making him realize that the array above was definitely a threat to him!

He regretted it, why did he lead that female demon to practice?

If he hadn't seduced the female demon to cultivate, this human cub might not have come down, and he wouldn't have wanted to set up a formation on this section of the ancient river channel!

This is called stealing a chicken without losing a handful of rice. Is it too late to regret it?

When the ancient demon soul was regretting it, Yin Dong divided a wisp of soul flame into the array and turned into the array spirit control array.

Then, he asked the Blood-Devouring Tree to divide a small sapling, containing a trace of tree spirit, and it was also planted in this 49 Guiyuan Formation. The blood water transformed by the rotten divine snake was blocked by the blood pool formation and could not be taken out. Yin Dong took some dragon blood out, watered the small sapling, and used dragon essence to accumulate the tree spirit.

The saplings sprouted quickly and grew into a blood-devouring tree more than one meter high at a speed visible to the naked eye. The tree spirit was also raised and strengthened by the dragon Yuanyun. When it merged with the array spirit, it could swallow the power of the formation to strengthen the tree body and grow faster.

Not long after, a towering tree more than ten meters tall appeared in the formation. Thousands of branches stretched out in the formation, and their roots quickly stretched towards the deep center of the earth, absorbing energy from the ground.

When the formation was operated, energy from all directions rushed towards the formation defense cover, forming a huge vortex, which was at least ten times larger than the vortex made by Yin Dong.

What is a bit strange is that the operation of this formation does not seem to be disturbed by the magnetic field. Yin Dong swallowed the power of the formation within the formation, and the magnetic field interference also disappeared.

"Huh! This scammer interference is finally gone." Yin Dong breathed a sigh of relief and asked casually: "God of Shell, have you come alive?"

He had no hope at all, but unexpectedly he received a reply from the mysterious shell - What the hell is you going to, causing this great god to be suppressed?

Yin Dong was so happy: "If you didn't suppress you, you're content. This place is called the Demon Valley. An ancient troll fell. Do you know what an ancient troll is?"

The mysterious shell was silent for two seconds, and then couldn't help but curse - what luck would you do with your kid? Can you encounter such a place?

"Haha, it's not me, it's my wife's luck. If she hadn't had some sense, I wouldn't have gone deep into this place. Brother Shell, I've lost some energy to the blue crystal for you. I wonder if you like it?"

When Yin Dong asked, he used to induce the spiritual arts illustration and scan the blue crystal.

Suddenly, the starlight appeared in his mind, transformed into starlight in the sky. After a while, it condensed into tadpole texts, and then transformed into the four words "Spiritual Illustrated Book".

When the four characters disappeared, a pattern like the blue crystal appeared, accompanied by pictures.

Blue Magic Crystal: Saint-level.

There is also a * number at the back. After clicking, there is a detailed description.

Blue Immortal Crystal and Blue Immortal Sand are both condensed by blue Immortal flowing light. The application range is also very wide, and the effect is very amazing. Like Blue Immortal Sand, it contains energy to replenish mental power, waste after purifying spiritual energy, and can also make psychedelic drugs. The difference is that the two attributes are cold and the blue Immortal Crystal is cold and the blue Immortal Sand is hot.

Mysterious Shell replied - Blue Fantasy Crystal is good, I like it very much. If you lose a little more, the more you will be better!

"Don't worry, I seem to have found a big fish under the ground!"

Through the formation spirit, Yin Dong sensed the ancient demon soul underground, and his eyes suddenly shone, and he could have found this old guy!
Chapter completed!
