I only reached the Foundation Establishment stage at eighty years old, and then the system appeared.

Yang Hongbo moved with lightning speed, weaving and dodging through the cavern, locked in combat with the peak seventh-tier demonic beast. Each clash between his sword and the beast's claws sent sparks flying, flashing in the dim cavern.

"Hmph, a mere seventh-tier peak demonic beast dares to stop me!" Yang Hongbo sneered, his chaotic power surging wildly within him and pouring into his longsword. In an instant, the longsword shone brightly, like a blazing sun, illuminating the entire depths of the cavern.

The monster seemed to sense the threat, letting out an angry roar. Its three eyes blazed with light, its muscles bulged, and its power seemed to have increased even further. It leaped up suddenly, pressing down on Yang Hongbo like a small mountain, its claws lashing out and creating gusts of wind.

Yang Hongbo's eyes narrowed. Instead of retreating, he advanced, his figure transforming into a streak of light as he met the demonic beast head-on. At the moment of imminent collision, he shifted to the side, skillfully dodging the beast's attack. Simultaneously, he slashed with his longsword, unleashing a sharp sword aura that struck the beast's abdomen.

"Pfft!" The sword energy sliced ​​through the monster's abdomen as easily as cutting tofu, and blood gushed out. The monster let out a miserable cry, fell heavily to the ground, struggled a few times, and then lay still.

Yang Hongbo sheathed his sword and stood there, catching his breath. Looking at the dead monster, he thought to himself, "The monsters in this cave are indeed troublesome. If it weren't for the protection of the Emperor's Bell and the support of the Chaos Power, I'm afraid it would have been difficult to deal with them."

He didn't linger and continued walking towards the tenth-tier spiritual herb. However, just as he was about to touch the herb, several more demonic beasts surged out from all directions. These demonic beasts varied in form, but their strength was considerable, with the lowest being at least sixth tier.

"It seems that these tenth-grade spiritual herbs are indeed not so easy to obtain." Yang Hongbo frowned slightly, but his eyes were filled with determination. He swung his longsword and once again engaged in battle with the demonic beasts.

Sword light flashed, and the screams of the demonic beasts rose and fell. Yang Hongbo, like a war god descended to earth, charged through the horde of beasts, felling them wherever he went. After a fierce battle, he finally slayed all the demonic beasts.

"Finally, I can harvest this tenth-grade spiritual herb." Yang Hongbo wiped the sweat from his face and reached out to grab the herb. Just as his hand was about to touch the herb, a powerful force suddenly surged forth, forcing him back several steps.

"Huh? What's going on?" Yang Hongbo was startled and looked around warily. Deep inside the cave, a mysterious light flickered, and a sinister aura permeated the air.

"Could there be something even more powerful inside this cave?" Yang Hongbo wondered to himself, cautiously approaching the source of the shimmering light. As he drew closer, the light grew brighter, and the eerie atmosphere intensified.

When he finally reached the light, the sight before him astonished him. A colossal ancient array stood there, radiating a mysterious light, from which a chilling wind emanated. In the center of the array, a spirit corpse floated silently, its body emanating powerful spiritual energy, even stronger than that of a cultivator at the peak of the Tribulation Transcending stage.

"So that's how it is. This eerie wind was actually formed by the ancient formation drawing spiritual energy from it, and this spirit corpse is the core of the formation." Yang Hongbo suddenly realized.

Just then, the spirit corpse seemed to sense Yang Hongbo's arrival and slowly opened its eyes. A strange light flickered in those eyes, sending chills down one's spine.

"Human, why have you trespassed into this place?" the spirit corpse spoke, its voice low and hoarse, as if it came from hell.

Yang Hongbo's heart skipped a beat, but he quickly calmed down and said, "I stumbled in by accident. I only came here because I heard there were tenth-grade spiritual herbs. I didn't expect to find this ancient formation and you instead."

The spirit corpse sneered, "Tenth-grade spiritual herbs? That was just bait I deliberately laid out. Everything in this cave is a trap I set to lure greedy humans like you."

Yang Hongbo frowned: "Why did you do this? You extracted spiritual energy, created the Yin wind, and caused countless cultivators to lose their lives. What is your purpose?"

A glint of madness flashed in the spirit corpse's eyes: "Purpose? My purpose is resurrection! This ancient formation was set up for my resurrection; it draws spiritual energy to nourish my body. As long as I absorb enough spiritual energy, I can be fully resurrected and return to the world!"

Yang Hongbo was shocked: "Resurrection? You actually want to be resurrected! Do you know what kind of disaster your resurrection will bring to the world?"

The spirit corpse sneered, "Disaster? What does that have to do with me? I only care about my own resurrection. Human, now that you've come here, don't even think about leaving alive. Become nourishment for my resurrection!"

After saying that, the spirit corpse waved its hand, and a powerful force rushed towards Yang Hongbo. Yang Hongbo was prepared. He activated the Human Emperor Bell to protect his entire body, and at the same time, he swung his longsword to slash at the force.

With a deafening roar, the forces collided, generating a powerful shockwave. Yang Hongbo was thrown back several steps, but the Emperor Zhong steadily protected him.

"Hmph, you've got some skill. But that's far from enough!" The spirit corpse sneered and launched another attack. With a wave of its hands, countless gusts of yin wind shot towards Yang Hongbo like sharp blades.

Yang Hongbo moved with incredible speed and agility through the eerie wind. He wielded his longsword continuously, shattering each gust of wind. Yet, the wind seemed endless, flowing without ceasing.

"This can't go on; we must find a way to break the formation," Yang Hongbo thought to himself. While fending off the attacks of the yin wind, he observed the structure of the ancient formation.

After some observation, he finally discovered a flaw. Although the formation was powerful, it had a crucial node; if this node was destroyed, the formation would fail.

"That's it!" Yang Hongbo's eyes lit up, and he flashed towards the crucial point. The spirit corpse seemed to sense his intention, letting out a roar and intensifying the attack of the yin wind.

Countless gusts of yin wind rushed towards Yang Hongbo like a violent storm, but he was fearless. He channeled his chaotic power and forcefully broke through the obstruction of the yin wind. Finally, he arrived at the crucial juncture.

"Take this!" Yang Hongbo shouted, thrusting his longsword fiercely towards the critical point. With a "crack," the critical point was destroyed, the light of the ancient formation dimmed instantly, and the eerie wind gradually ceased.

The spirit corpse let out an angry roar: "No! You actually destroyed my great formation! I will kill you!" It pounced on Yang Hongbo madly, but without the support of the great formation, its strength was greatly reduced.

Yang Hongbo sneered, "Now it's my turn!" He brandished his longsword, unleashing a series of sharp sword energies towards the spirit corpse. Although the spirit corpse fought back with all its might, it was unable to stop Yang Hongbo's attacks.

The spirit corpse roared repeatedly, but because it could not use the vast spiritual power within its body, it was forced to retreat repeatedly by Yang Hongbo. Yang Hongbo, having been freed from the invasion of the yin wind, was now able to use magic attacks.

Judging from the physical strength of this spirit corpse, it barely reaches the Void Realm. As long as I use mental attack spells to shatter its consciousness, I might be able to obtain a decent avatar.

So Yang Hongbo began to use mental spikes and divine cones to fiercely attack the spirit corpse's sea of ​​consciousness. Although the spirit corpse's physical body was still strong, it lacked mental defenses and was quickly overwhelmed by the mental spikes.

Because this spirit corpse was well preserved, it was almost indistinguishable from a living person. As long as a segment of one's divine consciousness was split off and entered into its sea of ​​consciousness, one could perfectly control its body and use it as one's own avatar.

Yang Hongbo released Yang Tian and asked him to guard the place. He began to split his consciousness, which was extremely painful, as if someone was forcibly cutting his body in two with a knife. Yang Hongbo was sweating profusely, enduring the pain of self-harm.

Half an hour later, the split of consciousness was successful. Yang Hongbo placed the split consciousness into the spirit corpse's sea of ​​consciousness, and the spirit corpse suddenly opened its eyes.

"Haha, my true self, from now on I am your avatar!"

"You should return to my secret realm to cultivate your techniques. Otherwise, you'll only be able to use your physical body and won't be able to use magic, rendering your vast spiritual power useless!"

The spirit corpse obediently entered the secret realm, while Yang Hongbo led Yang Tian to search for ninth and tenth-tier spiritual herbs and medicines throughout the cave.
