Cao Guojiu Devotes Himself to the Dao and Gains a Fortuitous Opportunity
However, Ao Changsheng didn't care, because even if Fairy Chang'e's Swordsmanship was superb, it still had its limitations.
For example, the final move of the Taiyi Mysterious Origin Sword Instruction, Taiyi Sword Qi, requires a cultivator at the Immortal Lord Stage to unleash its power. This is why Fairy Chang'e's signature sword moves are the Four Immortal-Slaying Swords.
This is also why Ao Changsheng taught Cao Guojiu the Taiyi Mysterious Origin Sword Instruction.
After Cao Guojiu left, Ao Changsheng disappeared.
Flying south.
After flying for a while, Cao Guojiu found himself in a mountain forest.
Countless Demon Beast dwell in these mountains and forests, and a thin mist shrouds them all.
This thin mist is the Demon King's domain.
Cao Guojiu also knew that the Demon King's domain was not a place that ordinary Demon Beast could enter. Even he dared not go there rashly. He could only find a secluded place nearby to cultivate.
This place is located in a valley.
The ground in the valley is covered with thick soil, and countless vines crawl on it. These vines are covered with moss and various poisonous insects, including centipedes, toads, and toad snakes.
Among the vines, there were many Demon Beasts, including demonic wolves and leopard cats.
These Demon Beast are all of a higher rank than Demon Beast. Around the valley, there are many trees, all of which are demonic plants. However, these demonic plants are of a much higher rank than ordinary demonic plants, and they also bear demonic fruits, which emit a rich fragrance.
Cao Guojiu had seen many demonic plants along the way, but he had never seen any like these. Moreover, these demonic plants were all mature. Looking at these demonic plants, Cao Guojiu couldn't help but reach out his hand, wanting to pick a demonic fruit.
However, as soon as Cao Guojiu reached out, his body was suddenly pulled by a suction force, and he was thrown onto a tree.
On this tree, a giant centipede was coiled up. There was a large mouth on the centipede's head, and inside its mouth were two black spheres, from which wisps of black smoke were rising.
"What a terrifying demonic Yao Qi."
Cao Guojiu was startled and quickly circulated his internal energy to resist the invasion of Yao Qi.
However, under the invasion of Yao Qi, Cao Guojiu's power quickly declined.
"Pfft!"
Cao Guojiu coughed up a mouthful of blood.
"As expected of the Demon King's domain, it is indeed so powerful."
Cao Guojiu was somewhat horrified.
The Demon King's domain is not a place that just anyone can enter. This is why the Demon King is called the strongest being in the Demon King Demon Realm, and why even Sage hold him in great awe.
They dared not enter the Demon King's domain.
"Huh, someone's here?"
At this moment, the giant centipede suddenly let out a hiss, then opened its huge mouth, and a thick tongue suddenly curled towards Cao Guojiu.
Although this centipede has no wings, it is incredibly fast and possesses potent venom. If Cao Guojiu is bitten by this centipede, he will immediately become a corpse.
Seeing this, Cao Guojiu didn't bother to retrieve the demon core and other treasures, and immediately used teleportation to escape.
"Whoosh!"
After Cao Guojiu used his teleportation ability, the centipede's giant tail slammed into the mountain peak where Cao Guojiu was standing. Instantly, the entire mountain peak shattered, and rocks flew everywhere.
"Boom!"
After the rocks collapsed, a huge pit was revealed, with mud flying everywhere, and a massive, deep crater appeared.
Seeing this deep pit, Cao Guojiu's heart skipped a beat.
This giant centipede destroyed its own mountain with a single blow; it seems its strength is definitely above that of Demon Sage.
Moreover, this centipede has extremely strong defenses; even if a small mountain were torn apart by its venomous fangs, it would not be harmed in the slightest.
After thinking for a moment, Cao Guojiu took off the bundle on his back and then took out a long spear from it.
Cao Guojiu obtained this spear from an ancient tomb, and he knew that a powerful weapon was hidden inside.
The most powerful weapon among these spears is called the 'Demon-Slaying Spear,' and it is made from a single nine-section steel bar.
This Demon-Slaying Spear contains malevolent Sha Qi that can slay evil. Once it encounters Demon Race or Human Race cultivator, it will exert a special attraction, drawing the Human Race into the spear, refining them, and turning them into a part of the spear, making them a puppet.
Although this Demon-Slaying Spear is only a low-grade Immortal Artifact, it can grant a person the combat power of Immortal Lord.
The Demon-Slaying Spear is a formidable weapon of attack, possessing extraordinary power. It also contains the power to slay evil, and anyone who comes into contact with this power, no matter how powerful a cultivator, will be devoured by it.
"Whoosh!"
The Demon-Slaying Spear drew a beautiful arc in the air before shooting out.
The shot was incredibly fast, reaching the centipede in the blink of an eye.
Sensing danger, the centipede let out a strange roar, then swung its giant claw, slamming it onto the Demon-Slaying Spear.
"Boom!"
A deafening roar shook the entire space within the Demon King's domain, sending countless Demon Beasts and plants flying. Some of the weaker demonic Demon Beast perished instantly.
"Awoo!"
The Demon King let out an angry roar, and at that moment the centipede's tail lashed out several times, striking Cao Guojiu's chest.
"Bang!"
Cao Guojiu's sternum broke, and his body flew backward like a cannonball, crashing heavily to the ground.
The impact shattered Cao Guojiu's sternum, and the spear pierced deeply into Cao Guojiu chest, causing Cao Guojiu body to sink into the ground.
Seeing his chest pierced through, Cao Guojiu's eyes flashed with intense fear as he gazed resentfully at the giant centipede in the sky.
Bright red blood flowed from the corner of Cao Guojiu's mouth, dripping down to his feet and staining the ground red. His pupils slowly dimmed; he was dead.
The centipede seemed to be thoroughly enjoying the sight of the blood on the ground, its scarlet tongue licking it incessantly.
The centipede's tongue was extremely sharp, and it instantly severed Cao Guojiu's throat. Cao Guojiu's eyes widened, and then his eyeballs rolled to the ground, dying with his eyes wide open.
This time, Cao Guojiu was completely dead, and his soul was scattered to the winds.
Meanwhile, after defeating Cao Guojiu, Yang Jian used his escape technique, which suddenly increased his speed to a terrifying level. In the blink of an eye, he appeared a million miles away, then leaped a thousand meters into a valley, and used his escape technique to rush off in one direction.
