The Wasteland Sand Worm King was several stories tall just by exposing the ground, and after the fire burned it, a hint of white-pink flames still glowed from the tall back of the hill from time to time.

However, it did not struggle like the rest of the sandworms, but with a slight shake, the flames dissipated directly.

Immediately afterwards, a savage aura filled the air, causing the sandworms that had already begun to flee in all directions to calm down again, dragging their charred bodies to breathe.

"Hmm..."

A wail from the ground sounded in the ears of the three of them, and the insect swarm instantly exploded like a pot, only to see the body of a mutilated insect begin to expand, the huge mouth opened, and the sharp teeth made a piercing sound towards the sky, and then turned into a cloud of blood mist in a "bang".

The explosion seemed to topple the dominoes, quickly causing a chain reaction of the swarm.

For a while, the empty wasteland was full of bangs, sounding like the continuous and overlapping sound of firecrackers on the night of the Chinese New Year's Eve.

Cheng Xing looked at this scene, and his heart was also horrified, in just a few seconds, nearly a thousand insects turned into blood mist, which also sharply reduced the size of the already shrunken insect colony.

"These bugs? Why blow yourself up? Xue Lingyu covered her mouth and nose with her hands, and immediately took out a gauze scarf to wrap around it, so as not to affect her mind because the blood was too strong.

"Could it be that this insect king wants to escape..."

Before Wang Cheng finished speaking, there was a shaking of the mountain in front of him, the back of the original small mountain suddenly sank, and the surrounding ground burst open.

I saw a huge mouth full of white sharp teeth sticking out from the collapsed place, and before Cheng Xing and the others could react, the giant mouth sucked violently, trying to absorb all these blood mist into the stomach.

The powerful suction force made the bodies of the three people suspended in mid-air shake one after another, and it was not until Cheng Xing's palm made a move that the raging flames offset the suction.

[The Wasteland Sandworm King is absorbing the flesh and blood left by the sandworm after the self-explosion to enhance his own strength. 】

[However, the host doesn't have to worry too much, although the Wasteland Sand Worm King has an ancient bloodline and is strong, but for some reasons, he can't transform now, and his combat power is not strong, even inferior to ordinary seventh-order demonic beasts. 】

With the information given by the system, Cheng Xing also had some confidence, and with a wave of his palm, the flames began to fly towards the Sand Worm King, and the blood mist he came into contact with along the way directly froze into a white mist.

"Don't panic, this is just a secret method of the Sand Worm King, by absorbing the same kind of flesh and blood to enhance his strength in a short period of time." Cheng Xingdao.

"Look how I smashed it to the ground."

Although after the previous consumption, the fighting energy in the body is no longer very abundant, but Cheng Xing does not feel a trace of tiredness, and can even feel that the free fighting energy between heaven and earth is being pulled by the exercises, constantly surging into the body, this may be the last sign of the Dou Wang advancing to the Dou Huang, and at the same time, it is also warning Cheng Xing that there is not much time left.

After saying that, Cheng Xing wrapped his body with strange fire, and white clouds appeared under his feet, drawing a strange path in mid-air.

Xue Ling saw that Cheng Xing had taken the lead, so naturally he would not stand idly by, his palms were quickly wrapped in cold, and his eyes became extremely cold, Wang Cheng just glanced at it, and he felt extremely cold, so cold that a thin layer of ice was hung on his eyebrows.

"Senior sister, it's not been long since you've healed."

"I can't do so much now!" Xue Ling's cold words spit out lightly from his mouth, and then his body turned into a little cold light, and he followed closely behind Cheng Xing.

Although he used the alien fire to freeze some of the blood mist directly into ice cubes, most of the blood mist was still swallowed by the Sandworm King.

On the ground in a radius of kilometers around the Sandworm King, there were only ten sandworms with the strength of the Dou King active.

However, due to being controlled by the Sand Worm King, these wasteland sand worms don't seem to have much autonomy, and even Cheng Xing's direct collision can't react.

Cheng Xing's flame-wrapped fist slammed into a five-meter-long sandworm, and the terrifying fist wind was blessed by the high temperature of the fire, like a hob cutting lard, and in a burst of sizzling sound, several sandworms were blasted out of a big hole, and then turned into an ice sculpture and collapsed to the ground.

In the face of Cheng Xing's rapid attack, the Sand Worm King also seemed to sense that these little minions would definitely not be able to deal with him, and the huge body was rolling underground, and the entire ground suddenly rose like a wave, and the sky became dull in an instant, and the sky was full of smoke and dust like fog covering the earth.

"Want to obstruct the view? Then let you taste the taste of the cold fire of the bone spirit. ”

Cheng Xing rubbed his hands, and the white-pink flame was separated, and the cold fire of the white bone spirit looked particularly enchanting under the yellow sand.

"Go"

With a wave of his palm, the cold fire of the bone spirit dragged out a white smoke in the air, and the terrifying high temperature was skillfully stimulated by Cheng Xing, and the existence of both fire and ice made the smoke and dust in the sky disappear quickly.

Against the backdrop of the flames, Cheng Xing also saw the true face of the Sandworm King of the Wasteland for the first time.

The cylindrical body is covered with hard, human-sized hairs, each of which is extremely sharp and embedded in every part of the body, powering the king of sandworms to move underground.

Roughly speaking, this Sand Worm King's body alone is seventy or eighty zhang, and his body size is already a very anti-heaven existence among the demonic beasts, so it is no wonder that he can't transform into a shape.

Looking at such a tall sandworm king in front of him, Cheng Xing bit the tip of his tongue lightly, and a little essence blood spurted out, and then mobilized the fighting energy of his whole body to frantically pour into the flames.

"Alien Fire Condensation!"

Cheng Xing burst into a shout, and the cold fire of the white bone spirit condensed into a ball in mid-air, and in a few breaths, a fire dragon more than a foot big rose into the air.

"Go!"

"Heavenly Ten Thousand Swords"

Xue Ling immediately let out a coquettish shout, and dense ice swords appeared around the fire dragon, which were also white, but they were two completely different attributes.

After the two glanced at each other, Cheng Xing was also moved, the cold fire temperature of the bone spirit was restrained, but the outer layer showed white ice, and they flew towards the head of the sand worm king that was as tall as a mountain.

"Roar"

The head of the Sandworm King, which had no sensory organs, trembled slightly, and then opened its mouth and sprayed at the two of them, and the terrifying yellow sand burst out at an extremely fast speed, threatening to drown the fire dragon in the blink of an eye.

"Hmph, Sword Formation"

"On"

Xue Ling snorted coldly, and the ice-white flying sword was like a protective net, blocking all those extremely fast flying sands, but at the same time, it was also suffering a huge attrition, and it could be seen that the ice sword that was constantly broken at the tail turned into ice crystal powder.

"If it's just this trick, then you'd better go back to the West as soon as possible."

Cheng Xing flicked his finger, and the fire dragon accelerated violently, and at the same time released a terrifying temperature, and the ice sword wrapped in Xue Ling directly stabbed the body of the Sand Worm King.

"Burst"

In an instant, the entire earth seemed to lose its voice, and only a strong white light flickered.

The mountain-sized body of the Sand Worm King was directly blown through by the two of them, half of the mouthparts were missing, and the rest of the parts were covered with thick ice, which spread nearly a hundred meters on the body before disappearing.

After eating this big blow, the Sand Worm King seemed to wake up and went crazy to get into the ground.

"It's going to run." Xue Ling's face was pale, and her cold words did not carry a trace of emotion.

"Run? No way. ”

Cheng Xing's palm curled slightly, and then a gray-white light burst out, and the terrifying power of Xuan Thunder pierced through the head of the Sand Worm King at an extremely fast speed.

There was only a boom, and countless ice crystals and dust splashed on the wasteland, and then the body of the Sand Worm King collapsed weakly on the ground covered with charred black and ice.

"It's... Killed? Wang Cheng was stunned when he watched from behind.

"The seventh-order Sandworm King, that's all... Dead"

"Ahem..."

Cheng Xing coughed violently a few times, and a strong sense of weakness was born the moment the fire dragon disappeared, and it was suppressed until it completely exploded.

"Fortunately, although this Sand Worm King has the strength of the seventh order, he can't play it, otherwise it is really not certain who will die or live today." Cheng Xing sighed in his heart.

Seeing that Cheng Xing's face was like a blank piece of paper, Xue Ling also quickly supported him, "What's wrong Cheng Xing, is it hurt somewhere?" ”

Looking at Xue Ling with a worried face in front of him, Cheng Xing shook his head with a wry smile, and said with his last strength:

"Place, Retreat"
