Swim!

Once wrapped by this spiritual spring of corpses.

The demon king secretly thought that something was wrong.

After the bone-eroding spiritual spring wrapped around his demonic body, it began to spin around his demonic body, trying to find a gap and penetrate into his demonic body.

The bone-eroding spiritual spring continuously washed and refined his demonic body, and a feeling of extreme cold came over him, which even froze the demonic energy in his body.

The demon king used his demonic energy to try to escape, but the corpse spirit spring tightly wrapped him up, greatly reducing his speed.

sizzle.

There were continuous and sharp explosions all around its demonic body.

This is the magic power and the bone-eroding spiritual spring constantly annihilating and melting each other.

Bai Qianhe also had a look of heartache. These spiritual springs from corpse bones that had been refined for hundreds of years would represent a huge loss every time a bit was consumed.

If he really had to fight this demon king one-on-one, even if Bai Qianhe could eventually defeat it, his bone-eroding spiritual spring would probably be exhausted.

Fortunately, at this moment, Cao Rui and other twenty Jindan powerhouses finally succeeded in condensing their second thunder attribute spell.

The thunder spells condensed by twenty powerful Jindan monks gathered into a huge and thick purple lightning beam, like a ferocious ancient thunder beast, rushing straight towards the Demon King who was tightly wrapped in the Bone-Erosion Spirit Spring.

Water and electricity blended together, and the purple lightning column attacked at an astonishing speed, accurately hitting the demon king who was bound and slowed down by the Bone-Erosion Spirit Spring.

"Bang!" Accompanied by a loud bang, followed by a crackling sound of electric electricity, Bai Qianhe clearly felt that the demon king inside suffered a heavy blow.

At the same time, a considerable portion of his bone-eroding spiritual spring was completely destroyed under the fierce bombardment of thunder and lightning.

The lightning spell condensed by the combined efforts of these twenty top-level Jindan-stage cultivators has reached its extreme power, enough to cause extremely serious damage to Yuanying cultivators!

"Extremely cold!" Bai Qianhe didn't care about the consumption of the Bone-Eroding Spirit Spring. He concentrated all his magic power to cast spells, wanting to take this opportunity to deal a heavier blow to the Demon King!

The bone-eroding spiritual spring controlled by him began to swirl again. Under the stimulation of magic power, the temperature dropped further, and thick white fog erupted around it. The fog was so frighteningly cold that the air around it was frozen into ice!

"Roar!" In the center of the Bone-Erosion Spirit Spring, the Demon King let out a heart-wrenching roar. Due to a moment of negligence, he was unable to use too many magical powers under the continuous attacks of the human cultivators, and he was already in a desperate situation of life and death!

He suppressed the raging demonic energy in his body, his eyes flashing with a faint blue light, locking onto Bai Qianhe!

hum!

A dazzling blue light flashed, and a terrifying demonic consciousness struck Bai Qianhe's soul like lightning.

Bai Qianhe's body shook violently, and he almost fell from the air. Black blood slowly flowed from his mouth and nose, and his face was as pale as paper.

With his eyes hazy, he relied on his willpower to control the bone-eroding spiritual spring and continued to entangle the demon king.

The Blue Hole Demon's signature magic skills obviously hurt him.

Cao Rui and the others did not dare to neglect it. Another purple lightning condensed and struck down! It hit the Demon King accurately!

Among the twenty Jindan cultivators, not one of them actually possessed a spiritual root with thunder attribute!

Including Cao Rui himself, he only has the five elements spiritual roots.

Even without thunder spiritual roots, one can still cast thunder spells, as magic power is inherently changeable.

However, without the thunder spiritual root to cast thunder attribute spells, the speed of converting thunder spiritual power, the casting speed, the casting consumption, and the casting power will all be greatly reduced.

Compared with the instantaneous spells that Cao Rui had previously cultivated to perfection in the Five Elements Magic, it was indeed extremely uncomfortable.

However, the Five Elements spells are just a tickle to the Demon King. Only the thunder attribute spells can cause fatal damage to the Blue Hole Demons. Using thunder attribute spells together is also a helpless act.

Rumble!

The lightning column, which was several meters wide, hit the demon king with endless power like a huge meteor.

The attack was so powerful that the demon king roared in pain, but he still tried to resist stubbornly.

However, under the dual pressure of the lightning pillar and the bone-eroding spiritual spring, the Demon King could no longer withstand such a powerful attack.

The demon body's recovery speed could not keep up, and it began to collapse, and the demonic energy in its body instantly fell into chaos.

With a loud bang, the demon king's body exploded like a volcano, and countless violent demonic energies poured out.

These demonic energies were like a raging storm, sweeping in all directions.

"Retreat!" Bai Qianhe shouted loudly, and the monks of the assault team used escape techniques to retreat quickly.

Bang, bang, bang! A series of dense explosions sounded, and the chaotic magic energy formed a terrifying shock wave, spreading to the surroundings with overwhelming force.

Everything in the area was reduced to ruins by the shock wave. Whether it was the tall palace or the magic stone tiles on the ground, they were all blown to pieces in an instant.

Although the Jindan monks of the assault team each used their escape lights to escape, they could still feel the huge threat posed by the self-detonation of the Demon King's body after his death.

After a moment, the horrific shock wave gradually subsided.

The fall of this demon king caused a shocking self-explosion, which eventually left behind a huge deep pit with a diameter of dozens of miles.

The deep pit was filled with smoke and a burning smell, as if it was a dead place.

The Demon City, which had just been built halfway, was mostly destroyed in the explosion caused by the Demon King's death.

The demon generals and demon spirits around fled in panic.

The demons were also aware of the situation. This group of human cultivators were so powerful that even the Demon King was killed.

If they go up again, they will only die.

However, some demonized humans and demonized monks who were building the city wall looked at the human monks flying across the sky and couldn't help but cheer with tears in their eyes.

They seemed to recall the prosperity of the human race when the human cultivators controlled the Qingzhou continent.

Perhaps some of them regretted becoming demonized, but having already merged with the evil spirit, they no longer have the ability to become human again.

"We have successfully killed the Demon King on the Western Front. Our basic goal has been achieved."

"It can be considered a heavy blow to the Blue Hole Demon Clan."

"Next, Jie will probably personally take action to deal with us."

"You guys go back to the natural chasm and return to Hongzhou on your own, and bring back the news you got about the demons."

Bai Qianhe appeared with a somewhat pale face and spoke. It was obvious that the devil's magical powers before his death had caused him considerable damage.

"Commander, why don't you join us?" Young Master Yunxiao asked with a frown.

"I have some things to do, but it has nothing to do with you."

"You all should leave immediately. This is an order." Bai Qianhe said without further ado. He flew away alone into the distance.

The speed was so fast that the Jindan monks in the assault team could not keep up.

The Jindan monks of the assault team looked at each other, and finally decided to follow Bai Qianhe's instructions and return to the natural trench first.

When the escaping light returned along the original route, two beams of light quietly left the team.
