In an instant, Qin Ze and Zhang Yuechen attacked simultaneously. Their figures flashed like ghosts, their speed so fast that no one could react. Qin Ze's sword transformed into a streak of light, piercing straight towards a cultivator's vital point. Zhang Yuechen, on the other hand, conjured a ball of flame in his hand, instantly enveloping another cultivator.

The sword light pierced through flesh, flames burning with life force; the two cultivators had no time to react before collapsing dead. The other team members also sprang into action, quickly taking down the surrounding guards.

Chaos erupted in the hall as the cultivators frantically searched for their attackers. Qin Ze and Zhang Yuechen appeared and disappeared in a blur, their attacks swift and deadly, having already felled several cultivators in a short time.

When the high-ranking cultivators of the United States realized the crisis, they all activated their cultivation power to prepare to resist Qin Ze and Zhang Yuechen's attack. Powerful energy surged within their bodies, forming layers of dazzling light, like shining stars.

A cultivator brandished his magical artifact, unleashing blazing flames in an attempt to trap Qin Ze and Zhang Yuechen. However, Qin Ze sneered, his aura suddenly surging, a powerful force sweeping over them. He stretched out his hand, his palm turning, and the flames vanished without a trace.

At the same time, a resolute glint flashed in Zhang Yuechen's eyes. His sword danced like the wind, its dazzling light slicing through the night sky. A cultivator tried to dodge, but found his movements slowed, as if bound by an invisible force.

Qin Ze and Zhang Yuechen's strength had long surpassed that of ordinary cultivators. With years of cultivation and experience, they had already etched a complete battle plan into their minds. Their confidence in confronting the high-ranking cultivators from the United States was unwavering.

Qin Ze took a step forward, his steps light yet seemingly carrying immense pressure. With a flick of his finger, a powerful current of energy appeared out of thin air, completely shattering the attack of one cultivator. Then, his figure flashed, as if he had instantly teleported to the side of another cultivator, his sword light slicing through space, aiming for a vital point.

Zhang Yuechen's sword danced like a dragon, each strike imbued with destructive power. His gaze was cold and sharp, his attacks swift and precise. A cultivator attempted to cast a defensive spell, but under Zhang Yuechen's sword, his defenses crumbled instantly; he was pierced by the sword's light, his body trembling as he collapsed.

The cultivators' defenses gradually crumbled before Qin Ze and Zhang Yuechen, as they felt an irresistible force. Just as they were filled with fear and helplessness, Qin Ze and Zhang Yuechen's attacks grew increasingly fierce, as if they had transformed into a merciless storm, sweeping everything away.

A cultivator tried to escape the battlefield, but was stopped by Qin Ze's energy. His movements froze, and he watched as Qin Ze raised his hand and mercilessly slashed down.

In the eyes of the high-ranking cultivators in the United States, Qin Ze and Zhang Yuechen had become an insurmountable chasm. Their strength far exceeded expectations, and their attacks were extremely fierce, unstoppable by anyone.

In the end, Qin Ze and Zhang Yuechen's team successfully broke through the defenses of the high-level cultivators from the United States.

One by one, the cultivators fell into pools of blood, and the entire base descended into chaos.

During the battle, a resolute glint flashed in Qin Ze's eyes.

He knew that this operation was not only for revenge, but also to seize that rare item, which was crucial to his cultivation.

He dealt with every practitioner without mercy, determined to complete his mission.

At the same time, alarms sounded within the base.

With reinforcements from the United States arriving to provide support, Qin Ze and Zhang Yuechen's mission became even more urgent.

They constantly flashed and made moves, engaging in fierce battles with the reinforcements.

Despite the large number of reinforcements, Qin Ze and Zhang Yuechen's combat experience and strength allowed them to maintain the upper hand throughout the battle. In the fierce fighting, they deflected wave after wave of attacks, gradually forcing the reinforcements back.

Qin Ze stepped into the room, his gaze sharp as lightning, quickly scanning his surroundings. Inside, he sensed a powerful aura—the aura of a cultivator, and one that felt strangely familiar. When his gaze locked onto the figure in the center of the room, his eyes narrowed slightly, a cold smile appearing on his face.

The figure was the leader of this base. When he saw Qin Ze, a look of surprise flashed in his eyes. "Qin Ze!" His voice was filled with shock and anger, as if he hadn't expected Qin Ze to find this place.

Qin Ze nodded slightly, staring at him coldly. He knew that the man in front of him was the mastermind behind the entire attack.

"Did you send people to kill me?" Qin Ze's voice was calm and cold, devoid of any emotion. He questioned directly, without beating around the bush.

The other party did not deny it; he admitted without hesitation, "Yes, it was indeed someone I sent. Qin Ze, you have quite the nerve to dare to trespass here."

Before the other person could finish speaking, a powerful surge of cultivation energy suddenly erupted from his body. Instantly, his aura became profound and mighty, and his body seemed to transform into a mountain, exuding a chilling oppressive aura.

A cold smile crept across Qin Ze's lips; he had already prepared for this. He took a deep breath, and the power of reincarnation circulated within his body, forming a thin curtain of light that enveloped him.

The opponent's attack came like a ferocious beast, but under the restriction of the power of reincarnation, his movements became slow and heavy. Qin Ze stared at him coldly, then gently punched him, directly striking his aura.

An invisible force emanated from the fist, instantly tearing apart the opponent's cultivation power. The base leader's expression changed drastically; he struggled desperately, but he could not break free from the binding force.

Qin Ze's gaze was cold and ruthless. He approached step by step, his fists flashing and creating a raging storm. His opponent roared in pain, but was unable to withstand Qin Ze's attacks.

Finally, Qin Ze's heavy punch landed squarely on the opponent's chest, producing a dull thud. The base leader's pupils dilated instantly, and he coughed up a mouthful of blood, flying backward like a kite with a broken string.

He crashed into the wall with a loud thud, then collapsed to the ground. Qin Ze slowly walked up to him, smiled coldly, and with a flick of his finger, a surge of reincarnation power was transmitted, completely sealing the other's cultivation power.

"Don't think you can act tough in front of me," Qin Ze's voice was calm and cold as he looked down at the base leader lying on the ground.

Qin Ze took a deep breath. He knew time was of the essence and he couldn't afford to waste any more time. He directly used the power of reincarnation, channeling it into the mind of the base leader and beginning to read his memories.

Under Qin Ze's control, the base leader's memories unfolded, and images appeared one by one in his mind. From this, Qin Ze learned that this base was not only a hidden cultivator's base, but also a terrifying testing ground. The laboratories were filled with various experimental subjects, who had been stripped of their consciousness and became victims of experiments.

What shocked Qin Ze even more was the information about the Earth Core Essence in the base leader's memories. His safe contained three drops of this precious essence, a valuable resource that Qin Ze desperately needed.
