Zheng Tianyu was afraid of being overtaken, so he increased his speed to the limit along the way and ran hundreds of miles in one go.

It's a huge stone cave, and it's hard to see inside from the outside. At this moment, he was standing at the entrance of the cave, his eyes cloudy.

There were countless corpses at the entrance of the cave, which had long since decomposed, and only a pile of dry bones remained.

He hesitated for a while, gritted his teeth one last time, and rushed straight in.

It's just that he didn't see a stone slab about one meter and a half on the edge of the cave entrance, on which were written the three words Wuxu Cave.

If anyone knew about this cave, they would definitely be frightened, because this was one of the forbidden places in the cultivation realm, and there was absolutely no chance of survival for those who came here.

Legend has it that this was once a training ground for powerful sword cultivators, and later, for unknown reasons, endless sword qi was released here for three hundred consecutive years. Suddenly, all the sword qi in the sky disappeared, but the strange thing was that no one who came here could come out alive.

Before Zheng Tianyu approached, he felt a terrifying force pressing against his body, making his speed slower and heavier.

Not only the feeling of the flesh, but also the pain in his mind was unbearable, and it almost broke him.

"Ahh

Suddenly, Zheng Tianyu screamed, and in his mind, a powerful force suddenly oppressed, making his whole body tremble in pain and bleed.

Zheng Tianyu's whole body was bowed into a shrimp shape, and his whole body trembled wildly.

It was an indescribable feeling, like someone was pricking his soul with a magic needle.

It was a terrifying feeling that pierced his bones, and it terrified him.

Shout!

At this moment, in the depths of the cave, a sword rushed into the sky, slashing straight at it.

Laugh at!

The sound of things slashing on people's bodies sounded, and the sword light suddenly slashed at Zheng Tianyu's body, and then turned into a rain of swords.

Almost at the same time, a colorful long sword suddenly appeared in Zheng Tianyu's mind, and it was aimed at Zheng Tianyu's spiritual power.

Rumble!

At this moment, Zheng Tianyu felt like he had experienced an apocalyptic scene in his mind, and the world was trembling.

An indescribable sword made his whole world collapse and leave the table, never to live up to the past.

In the depths of his mind, a stream of blood began to ripple slowly, and as time passed, the speed of that blood rippled faster and faster, faster and faster.

Airplanes!

At some point, as blood filled his mind, all the cracks were repaired, and they became stronger than ever.

Another change, however, is incredible.

Because, the restored mind is no longer the same as before.

The blood was gone, replaced by pale blue water, as far as the eye could see, and I didn't know how big it was.

There was a drastic change in his mind, and his physical body naturally changed a lot.

First of all, his strength was at least twice as strong as before, and his limbs and bones were incredibly powerful.

The strength of the physical body has reached an unbelievable level, and even those old monsters in the cultivation world will be shocked when they see it.

Half an hour later, Zheng Tianyu woke up slowly.

As soon as he opened his eyes, he suddenly found an old man in black robe standing in front of him, who was looking at him with great interest at this time.

Zheng Tianyu trembled in fright, and said in a trembling voice: "You... Who are you?"

"Young man, how can your flesh be so strong?"

"Are you a hegemon?"

"No, even if it's a hegemon, it's even more impossible to wake up so easily. ”

Zheng Tianyu swallowed his saliva, he felt that this old man exuded an extremely terrifying coercion, if he really wanted to kill him, he only needed one thought.

After the black-robed old man muttered to himself for a while, he smiled and said, "My name is Sword Thirteen, and I have practiced swords, practiced swords, raised swords, and certified swords all my life. ”

As he spoke, the black-robed old man smiled bitterly: "It's a pity that he died under his own sword in the end, and in the end he became a sword soul." ”

Sword Thirteen, the absolute overlord of the sword cultivation world, but there was no trace after the battle with the Sword Saint seven hundred years ago, until three hundred years ago, the sword qi in the sky came out of the Wuxu Cave, and people speculated that this might be the cultivation ground of Sword Thirteen.

It's just that no one can confirm it, it's just speculation.

After all, Sword Thirteen's cultivation was too terrifying, and he was already a top figure in the cultivation world, how could he die so easily?

However, people are not as good as heaven, and when Sword Thirteen was about to refine a Divine Sword of the World, Divine Sword turned against the Lord and killed him with a sword.

Under the fierce resistance of the enraged Sword Thirteen, the Sword Spirit of the Sword God was finally killed, and he himself became the Sword Spirit.

Over the years, many people have come here to try their luck with sword cultivation, and for this reason, Sword Thirteen has set up three levels, but anyone who passes this can get the Colorful Divine Sword.

However, many people came here one after another, but none of them could survive the first test.

Originally, he didn't care about Zheng Tianyu at all, how could a person who hadn't started cultivation yet be able to pass the test that made him?

However, it turned out that he was wrong, and he was very wrong.

"Sword Thirteen?"

Zheng Tianyu muttered, he stood up, feeling like a giant dragon roaring all over his body, and a terrifying force erupted.

Zheng Tianyu couldn't help but let out a long roar, he roared, and hit the stone with a punch, and suddenly a continuous explosion came.

The entire cavern swayed violently under this punch, and it was about to collapse.

"Damn!"

Seeing this, Zheng Tianyu said to Jian Thirteen: "Senior, run." ”

As he spoke, he stretched out his hand to pull Sword Thirteen, but his hand went directly through Sword Thirteen's body.

Zheng Tianyu was stunned, and then tried a few more times, but it was still the same.

Jian Thirteen smiled slightly, waved his right hand, and in an instant, the sword qi in the sky was horizontal, and the entire Wuxu Cave was directly razed to the ground.

With a loud bang, the Wuxu Cave that had appeared for three hundred years disappeared directly.

Recite!

At this moment, a soft sword chant came from Tianyu, and Zheng Tianyu looked up to see that a divine sword shining with seven-colored brilliance slowly landed.

Red, orange, yellow, green, cyan, blue, purple, seven kinds of brilliance flashed alternately, hazy like a god, like a divine weapon.

It's a scene that is hard to depict, a seven-colored sword falling from the sky, radiating a thousand rays of light.

Sword Thirteen's eyes looked obsessively at the Seven-Colored Divine Sword that slowly landed, and said obsessively: "The Seven-Colored Divine Sword, also known as the Seven-Colored Sword, is made of seven peerless divine materials such as Xingchen Divine Iron, Heavenly Meteorite, Xingchen Steel, Ten Thousand Years Iron Tree, and Killing Stone, and it took thirty years to cast. The gods are a soldier, the wisdom is natural, and the gods are invincible. ”

Looking at the Colorful Sword, Zheng Tianyu suddenly thought of the Nine-Colored Sword Technique, the master said that the Nine-Colored Sword Technique actually only has the first seven kinds, and almost no one can practice the latter two, because the requirements are too harsh.

"This sword..."

Zheng Tianyu swallowed, his weapon was a soft sword, and he naturally longed for a powerful sword.

Sword Thirteen smiled and said, "This sword has now recognized you as the Lord, so it is naturally yours." ”

"If you don't like the colors, you can change them to any color. ”
