A vast surge of demonic power erupted, pouring entirely into the massive bone sword.

As the demonic power continued to flow into the sword, a heavy pressure emanated from the blade.

Lu Chen looked down at the bone greatsword, inwardly marveling:

"Even after infusing so much demonic power, this bone greatsword shows not a single crack. If it were any ordinary sword, it would have long since shattered from within."

Truly worthy of being the remains of a fifth-tier demon beast!

Thinking this, Lu Chen didn't hesitate. He activated the full force of the hundred-thousandfold gravity, pouring even more vast amounts of demonic power into the sword.

At this moment, the bone greatsword trembled slightly, its weight continuously increasing. Lu Chen felt as though he was holding up a massive mountain, as if the weight would bend his arm. The immense pressure surged like an endless tide, his arm muscles straining to their limit, veins bulging like coiled dragons.

It's about time!

Lu Chen clenched his teeth, mustering all his strength to lift the hilt. He took a few steps back, creating enough distance from the Shadow Malevolence Beast, then raised the greatsword high with both hands. A world-destroying aura emanated from him as he charged towards the beast!

The Shadow Malevolence Beast seemed to sense this terrifying power, a flicker of fear in its eyes. Its survival instinct drove it to prepare for a desperate struggle.

It opened its bloody maw, spewing out a denser cloud of white mist, attempting to block Lu Chen's advance.

Facing the oncoming thick mist, Lu Chen remained unmoved. With a roar, the bone greatsword in his hand, carrying boundless might, plunged straight into the mist.

The bone greatsword, enhanced by the hundred-thousandfold gravity, was immensely heavy. Even before the sword reached its target, the terrifying momentum it carried was already felt. Lu Chen's figure moved like lightning, creating a fierce gust of wind as he charged. The sheer force of his sword-wielding charge instantly dispersed the thick mist!

Lu Chen's figure emerged from the mist like a war god descending. In the blink of an eye, he was before the Shadow Malevolence Beast, bringing the sword down with a mighty slash!

This strike seemed to carry the power to split heaven and earth, the very space around it trembling.

The Shadow Malevolence Beast, terrified, tried to dodge, but it was already too late.

"Boom!"

A deafening explosion echoed, as if the entire cave was about to collapse.

The greatsword, with the terrifying force of the hundred-thousandfold gravity, cleaved the Shadow Malevolence Beast cleanly in half from head to tail.

The powerful shockwave spread out, causing rocks to shatter and the ground to cave in wherever it passed. The Shadow Malevolence Beast's body instantly turned to dust, dissipating into the air.

The cave finally returned to silence.

Lu Chen slowly withdrew the hundred-thousandfold gravity enhancement, feeling a wave of exhaustion wash over him.

"Whew."

"Activating the full hundred-thousandfold gravity is indeed too heavy."

He took a moment to catch his breath before mustering all his strength to pull the bone greatsword, deeply embedded in the ground, free.

The bone greatsword seemed fused with the earth. Lu Chen gritted his teeth, beads of sweat rolling down his forehead, his arm muscles taut, veins bulging like coiled dragons.

"Up!" With a shout, Lu Chen finally managed to pull the bone greatsword out of the hard ground bit by bit.

He held the sword, his gaze sweeping over it inch by inch, and couldn't help but praise:

"What a sword! Even with the full hundred-thousandfold gravity, not a single crack."

"Such a pity, though. In less than three hours, the demonic power in this sword will dissipate completely, rendering it useless."

Lu Chen sighed deeply, then suddenly noticed a faint, strange glow on the ground beneath his feet.

Curious, he crouched down and looked closely.

Within the glow was a smooth, translucent inner core, emitting a faint blue light.

At this moment, Su Li's voice, coming from the jade ring, exclaimed in delight:

"An inner core! You lucky fool!"

"This Shadow Malevolence Beast's inner core is different from others. It contains a unique fusion power. With this material, we can combine the celestial meteorite iron and the Red Flame Dragon's bones to forge you a peerless divine weapon!"

Hearing this, Lu Chen's eyes sparkled with excitement.

Just when I was lamenting the loss of the Red Flame Dragon's bones, an opportunity presents itself!

With the celestial meteorite iron and the fifth-tier demon beast's bones, how could we not soar?

Thinking this, he extended his spiritual sense and found the meteorite brick within a dozen feet. With a thought, the brick flew back into his hand.

"Master, what are we waiting for? All the materials are here. Let's fuse them quickly! In a few more hours, the demonic power in the Red Flame Dragon's bones will dissipate!"

But Su Li seemed hesitant, not responding immediately.

Lu Chen, anxious, pressed, "Master, what's wrong? Are we missing a key material, or is there not enough time to complete the fusion?"

Su Li sighed softly and said slowly:

"No, it's not about missing materials or time.

It's just that if I'm to forge this weapon, my spirit form must leave this jade ring and stay close to you. But if that happens, and Chu You sees me, it could lead to a lot of trouble."

Lu Chen chuckled, "That's simple. You just focus on forging. I'll handle Chu You."

Su Li still looked worried, "This is no small matter. Chu You is meticulous and a elder of the Hidden Blade Sect. If she discovers my existence, it could bring endless trouble."

"Moreover, to fuse these three materials, I'll need to use the strange fire, as well as the spirit stone anvil and hammer, which will make a lot of noise."

Lu Chen, however, was confident, "Don't worry, I'll handle Chu You."

Su Li frowned, "What's your plan?"

Lu Chen grinned, "I'll just dual cultivate with her."

???

Su Li was stunned, "Even if you dual cultivate, you'll need to stop at some point. Can you keep going for three hours straight?"

Lu Chen laughed, "If I cultivate her until she passes out, she won't be able to hear or see anything."

Su Li's lips twitched, "Don't brag. You?"

"Make her pass out from dual cultivation???"

"Have you forgotten the time Chu You forced you to dual cultivate for twelve hours straight?"

Lu Chen's face turned pale at the reminder.

Indeed, during his first dual cultivation session with Chu You, he was only at the Foundation Establishment stage, while she was at the Golden Core stage. He had been completely dominated, utterly humiliated.

Thinking of this, he was even more determined to reclaim his pride.

Lu Chen stubbornly retorted, "That was different. I'm at the Golden Core stage now, and my physical strength has improved."

Su Li continued to tease, "Hmph, don't get too cocky. You might just end up being dominated again."

"Don't worry about it," Lu Chen said, pointing to a hidden spot in the cave. "You just focus on forging here. I'll handle the rest."

With that, Lu Chen turned and walked towards where Chu You was, no longer paying attention to Su Li.
