Devouring the essence blood dripping from Xia Xuan's palm, above the pitch-black key, the black light slowly flickered, as if he was reminiscing about the taste of the former's blood.

An inexplicable emotion like the fluctuation of human heart is also slowly transmitted from the key!

Realizing this emotion, Xia Xuan's pupils suddenly shrank to the size of a pinhole. Because, he seems to vaguely understand that there is a certain message that this emotion wants to convey, and that is......

For the smell of blood in his body, this key ...... Seems to like it very much?!

Rumble!

Almost at the moment when Xia Xuan's somewhat frightened emotions fell, an even more terrifying suction force erupted directly from the key!

Under such a terrifying suction, the wound in Xia Xuan's palm, which was originally only the size of a thin line, suddenly cracked, and at the same time, the large amount of blood also gushed out from Xia Xuan's palm like a fountain from it, and all of it was sprinkled on the pitch-black key.

Soaked in Xia Xuan's large swath of blood, the pitch-black key began to devour the blood frantically.

And as Xia Xuan's blood was devoured by it, the pitch-black color on the key became deeper and deeper, and at the same time, the original incomplete places were like human flesh and blood, and began to grow and recover!

", what the hell is this thing doing?!"

The blood in his body quickly left his body, Xia Xuan's face turned pale quickly, and he scolded in horror in his heart, and then he began to struggle frantically.

The left hand that was still able to move was clenched, and the power in Xia Xuan's body suddenly exploded, and he threw a fierce punch at the pitch-black key!

Five rings, a million heavenly fists!

Boom!

The terrifying power erupted directly, enough to directly blast an ordinary Yuan Envoy Realm Fivefold Heavenly Martial Artist into a blood mist, and as Xia Xuan's strength increased, the power of his punch became more and more terrifying!

However, this time, Xia Xuan's fist had not yet fallen, but a rather strong repulsive force suddenly appeared, directly forcibly stopping his extremely fast swinging fist, no matter how much he added strength, he couldn't shake half a point!

And almost as soon as Xia Xuan's offensive was stopped, he felt that the suction of the key to withdraw his blood suddenly stopped, but before Xia Xuan could breathe a sigh of relief, the terrifying suction became even more terrifying and crazy in his frightened eyes!

From the beginning to the present, it has only been a few breaths in the past, and Xia Xuan actually felt that nearly half of the blood in his body was forcibly stripped and devoured by this key!

If it goes on like this, after a few breaths, Xia Xuan will be directly drained of blood and die!

", this!"

With a furious scold in his heart, Xia Xuan was ready to use the power of the Heavenly God Tower to suppress this key, and then let himself escape from the Heavenly God Tower.

And as if he knew Xia Xuan's thoughts, when he was just about to use the power of the Heavenly God Tower, the violent suction of the key suddenly stopped, and then, before Xia Xuan could react at all, it turned into a light and shadow and rushed directly into his body.

The stinging pain from the palm of his hand made Xia Xuan's face change slightly.

Because the suction disappeared, the palm of his hand regained its ability to move, so that he directly withdrew it directly, looking at the palm of his hand, the originally torn wound was rapidly healing at a speed visible to the naked eye.

Immediately, Xia Xuan glanced at it with an ugly face, the stone pillar in front of him already existed, but the pitch-black key that was originally inserted there on it had completely disappeared.

The pitch-black key had entered his body!

Thinking of his previous action that almost swallowed his blood, Xia Xuan's face turned even pale, and his mind was about to enter his body at the moment, ready to expel this key from his body!

However, at this moment, the blank voice suddenly echoed in his mind.

"The keys. ”

"Unleash the potential power of all living things!"

It was just two sentences, but it made Xia Xuan's eyes tremble!

Open the power of all living things?!

What a domineering word!

In shock, Xia Xuan's consciousness sank directly into the dantian, and the scene in the dantian suddenly appeared in his mind. Immediately, he saw that at this time, the most important thing in the Yuan Force Vortex was that there was already a pitch-black object, and it was like a pillar of the earthquake sea, suppressed in it.

Look at that peculiar style and appearance, isn't it the key to rush into Xia Xuan's body on his own?

And, at this time, the key has also changed greatly, the broken and decayed posture is gone, perhaps because of the devouring of Xia Xuan's blood, on the key body, those broken and broken gaps are also completely restored to their original state at this time, and the pitch black color all over is also becoming more and more profound and condensed.

Completely different from the faint aura fluctuation before, there was a rather majestic and vast aura spread on the key at this time, as if it could contain everything in the world, which made De Xia Xuan feel very frightened.

Is this what the key really looks like?

In the shock of his heart, Xia Xuan slowly opened his eyes, his heart suddenly moved slightly, and a black light appeared from his palm, and the key that fell in the dantian suddenly appeared in his palm.

The palm-sized pitch-black key, like a relatively wide dagger, has been cut off the handle and dagger tip, with dark black lines entwined on it, looking quite mysterious and gorgeous.

Looking at such a simple key in his palm, feeling its heavy touch, Xia Xuan actually had a feeling of blood connection in his heart, as if the key in front of him was an extension of his arm, which could be controlled by him at will.

The previous one, which had paid the price of almost half of his blood, seemed to have recognized him as the master at this time.

"Can you unlock the potential power of all things?"

Whispering a sentence again, the information transmitted to him by the previous voice also showed a hint of interest on Xia Xuan's face. This key is so domineering introduced by that voice, and its ability should be quite extraordinary, right?

Thinking in his heart, Xia Xuan's palm suddenly flipped over, and a war knife suddenly appeared in his palm.

This war knife is really all in the ring, but at this moment, it is just right for him to do an experiment.

Holding the key tightly in his right hand, Xia Xuan carefully approached the blade and slowly touched it after groaning slightly.

While.

With a slight low sound, the strong and sharp blade fluctuated gently like the surface of the water, and the key slowly probed into the blade under Xia Xuan's slightly startled gaze!

Airplanes!

In an instant, on the bright blade of the sword, a pitch-black aura slowly surged out, and in an instant, the war knife was directly dyed into a deep pitch-black color!

At the same time, an indescribably terrifying aura of forest cold also swept away quickly from the battle knife!
