"Slash!"

Chu Feng raised his sword and slashed at the black demonic energy.

With this stroke, the power of the Immortal Sword Technique immediately became evident. The black demonic energy that Xiong Guansui couldn't cut through with all his might was as fragile as a floating cloud under Chu Feng's sword light.

Easily cutting it apart.

"Exterminate!"

The sword light vibrated at high frequency, stirring within the black demonic energy. In the blink of an eye, the black demonic energy disappeared without a trace.

This is the power Chu Feng possesses now.

"Transform!"

Seeing that Chu Feng was stronger than it imagined, the black Xuan Turtle immediately transformed.

Zuo Mjun, riding on the Xuan Turtle, showed a mad expression, with black demonic energy surging from his whole body. Then, bit by bit, he hid within the turtle shell of the Xuan Turtle.

It took less than three seconds, and Zuo Mjun had completely disappeared. The black Xuan Turtle stood upright, transforming into a half-human, half-turtle monster. Its head was identical to Zuo Mjun's, with two very short legs.

Its hands remained like turtle claws.

The body's torso was similar in height to a human's, except it wore a natural shell, with its back hunched. The turtle shell was mounted on its back.

"Let you taste the power of this godly turtle!" The black Xuan Turtle's body kept growing, eventually transforming into a demon three zhang tall. Muscles knotted together like they were congealed steel rods, full of explosive power.

Chu Feng merely looked at it indifferently, as if he didn't care about its transformation and demonization at all.

"Do you know why the Qiankun Sword Emperor left you back then?" Chu Feng looked at it with pitying eyes.

"Why?" The Xuan Turtle's tone was arrogant.

"Because leaving you to guard the passage into the Immortal Tomb had another purpose, specifically for testing the strength of the new generation of Qiankun Sword Emperors. To test the power of the new Sword Emperor's Swordsmanship."

Before he finished speaking, Chu Feng slashed the Dual Swords towards the Xuan Turtle.

"Heaven and Earth Sword Skill, Ninth Move, Independent Decision! Slash!"

A red and a white sword light transformed into two Sword Jiaos, intertwining from left and right. They slashed fiercely towards the Xuan Turtle.

Bang!

The turtle shell on the Xuan Turtle's body glowed with black light, even opening its mouth to spray out a dense blast of demonic energy, transforming it into a shield in an attempt to block the sword light.

But it was all in vain.

The sword light unleashed by Chu Feng was unstoppable, easily cutting through its demonic energy and then tearing apart the turtle shell.

"Ao~!"

The Xuan Turtle opened its mouth to emit a heart-wrenching scream. Its ugly face showed a pained expression.

"Why... The shell of this godly turtle is indestructible, even Innate Treasures find it hard to break. Yet, in the face of your sword light, it's so fragile... This godly turtle is unwilling..."

The Xuan Turtle's voice was full of intense resentment and fear.

Before making a move, it thought it was on par with Chu Feng.

"Fool, I told you, you were just left by the previous generation of Qiankun Sword Emperor to be a test stone for the new generation Sword Emperor, and you still didn't believe it!" After Chu Feng sliced its turtle shell open with a sword, he made a mental command. His demon body tunneled from the ground.

Three Heads and Six Arms, surging with demonic energy, as soon as it appeared, a terrifying Yin Wind arose.

"Swallow it, it will surely help you step up another level!" Chu Feng said to the demon body.

The demon body is now at the Lower Yama Realm, stepping up another level would make it a Middle Level.

Without saying a word, it dived towards the Xuan Turtle.

Although Chu Feng's sword light sliced the Xuan Turtle's body, it did not die. Any creature that resembles a zombie has a super healing ability, even if the head is cut off, it can still recover completely.

"No... This Xuan Turtle has lived for countless millennia, roamed freely in the underworld, and will never let you devour it!" The face of the Xuan Turtle kept changing, turning into its original turtle face and then into Ma Xiangjun's face.

Chu Feng just watched coldly.

He believed his demon body would surely devour the black Xuan Turtle.

Even if it couldn't, wasn't he, the master, standing guard here? If worse comes to worst, he could grant the black Xuan Turtle another blow.

The demon body was extremely fierce, manifesting three heads and six arms, crazily gnawing at the Xuan Turtle. At first, the black Xuan Turtle was able to resist strongly. Over time, it gradually gave out, its surrounding black demonic energy like a dying flame, slowly extinguishing.

"Spare me, spare me... As long as Lord Sword Emperor spares me, I will pledge allegiance to you and never betray..." The black Xuan Turtle started to loudly plead for mercy.

But for a demon like this, how could Chu Feng easily believe it?

Besides, he already had a demon body, which was essentially an incarnation of himself. Why distribute limited resources to a demon that could change at any moment?

Better to devour it completely.

The demon body did not disappoint Chu Feng, spending nearly three days to finally devour the Xuan Turtle.

Due to the vast energy of the Xuan Turtle, after devouring it, the demon body appeared extraordinarily bloated. A dense blood aura was visible around it, like a dark red blood flame.

"Go and digest it well!"

Chu Feng waved his hand, and the demon body swiftly tunneled into the ground and disappeared.

It was only after Chu Feng had fully mastered the Immortal Tomb of the Qiankun Sword Emperor that he was able to allow it to come and go freely. Previously, there was an immortal tomb restriction here that the demon body couldn't penetrate.

After dealing with the Xuan Turtle calamity, Chu Feng turned to look at the nearby Xiong Guansui.

This silly girl was still sitting with her eyes closed, healing.

She was now very trusting towards Chu Feng, letting her guard down completely, openly leaving her back to him.

If Chu Feng suddenly made a move, he could easily subdue her.

Chu Feng's gaze towards Xiong Guansui was very gentle. Time reveals the true nature of a person, distance tests the endurance.

Through this trip to the immortal tomb, he also recognized many people's true colors.

Ye Wu, who seemed friendly and always tried to please him, was actually a traitor who stabbed Chu Feng in the back at a crucial moment. If Chu Feng hadn't obtained the Qiankun Sword Emperor's legacy at the critical moment, he might have been long dead.

On the other hand, Xiong Guansui, who was always cold and proud towards him, showed a pure and kind side at the critical moment.

This is a girl worthy of respect.

Chu Feng did not wake her up, but turned his gaze towards the ghostly beings. Granny Meng, the Fan-holding Ghost King, and various ghostly beings all bowed in obedience to Chu Feng.

"To prevent you from causing trouble here, enter my Sword Domain and become the first living beings within my Sword Domain!" Chu Feng called to them.

After advancing to the Lower Sword Immortal, His Sword Domain had solidified from illusion, truly becoming a Sword Dao World. Everything within was real.

However, there were no living beings inside yet.

Chu Feng didn't dare to easily allow other living beings into his Sword Domain. Not that he feared losing control over them, but he worried that the collapse of the Sword Domain would result in their deaths.

Now, using these evil Yin Souls and fierce ghosts as the first test subjects.

If successful, in the future, all of Chu Feng's pets could enter the Sword Domain. It could also enhance the power of his Sword Domain.

Under his guidance, one by one, the ghostly beings orderly entered his Sword Domain.

Henceforth, he had another responsibility—diligently ensuring the integrity of his Sword Domain. In battles against enemies, he must take special care to protect them, preventing their annihilation.
