"From today onwards, you will come to me for eight hours a day, and after three days, it will be up to you to create your own creation. The middle-aged man said.

"Thank you senior!" Ye Feng was overjoyed.

"Don't be too happy yet, if you don't work hard to cultivate in the past three days, you will probably die at the hands of the stone man. The middle-aged man smiled: "The strength of those two stone men just now is too weak, I will make more powerful stone men to fight you." ”

"Don't worry, senior, I will work hard!" Ye Feng nodded firmly.

"In addition to the Nine Swords of the Human Rank, you seem to know other swordsmanship, but you haven't finished cultivating, am I right?" the middle-aged man said with a smile.

"That's right, there are a total of thirteen swords in that set of swordsmanship, and there are still two swords that the juniors have not learned. Ye Feng nodded.

"Come out and let the old man see it. The middle-aged man smiled.

Ye Feng nodded.

"Boom!"

The ground shook, and the rocks bulged into a stone man.

Ye Feng didn't wait for the stone man to attack, he took the initiative to sacrifice a wooden sword to kill the stone man, and a sword shot at the stone man, killing the sword and destroying it.

From a distance, the stone man was already shrouded in dense sword qi, and the terrifying murderous aura permeated the entire cave, making people palpitate.

Click......

Finally, cracks appeared on the stone man's body, shattered with a bang, and turned into rubble.

After killing the stone man, Ye Feng put away his sword and looked at the stone house, waiting for the middle-aged man to speak.

"Eleventh sword, you have achieved the unity of body and sword, what do you need to do with the twelfth sword?" the middle-aged man asked.

Ye Feng frowned and fell into deep thought.

"Your swordsmanship pays attention to the word 'fast', you have now reached the extreme of your body speed, if you can do it with your heart, you can use the twelfth sword, if you can achieve the unity of human sword, you can use the thirteenth sword. The middle-aged man said slowly.

Ye Feng's body shook, and he had a feeling of sudden enlightenment.

"If you can achieve the realm of forgetting both human swords, you may be able to create the fourteenth sword. The middle-aged man continued.

"People and swords forget ......" Ye Feng's face changed slightly, and he thought about it.

The middle-aged man didn't continue to speak, he opened a window for Ye Feng, as for how far Ye Feng could go, he could only depend on Ye Feng himself.

After a long time, Ye Feng took a deep breath, looked at the stone house and said, "Thank you seniors for your advice!"

"Hmph, when did the old man instruct you?" the middle-aged man snorted coldly.

Ye Feng smiled, he was already used to the moodiness of this middle-aged man.

"Boy, only under extreme conditions can human potential be stimulated, I will create this kind of condition for you later, you have to do your best, otherwise you don't know how to die, haha......"

The middle-aged man smiled, the ground shook, the rocks continued to bulge, and in an instant, they turned into eight stone figures, all of which were amazing.

Whoosh whoosh ......

The eight stone figures rushed towards Ye Feng almost at the same time, frantically swinging their fists to attack, and the fist wind roared, shaking all directions.

Ye Feng's color changed, and he released a destructive aura attached to the wooden sword, and a sword swept in all directions, and the sword qi was vertical and horizontal, shaking the eight stone figures away.

The eight stone figures were completely undamaged, they stabilized their figures, and pounced on Ye Feng again, either with fists or palms, and launched a new round of attacks.

Ye Feng took out his sword like lightning, and the wooden sword kept flashing, hitting the stone man's fist every time, stirring up sparks all over the sky, and the sound of collision was endless.

From a distance, the entire cave was full of Ye Feng and the figures of the eight stone figures.

"It's unbelievable that the seventh level ......of the Body Refining Realm has such a powerful power," inside the stone house, the middle-aged man muttered to himself, his eyes full of appreciation.

......

Three hours later, calm finally returned to the cave, Ye Feng sat on the ground panting, and next to him, there were eight broken stone figures.

Although Ye Feng had successfully defeated the eight stone men, he himself had suffered a lot of injuries, and if he hadn't used the Blood Burning Secret Technique, he would have been defeated long ago. Of course, he didn't use the Great Sword Seed and Devouring Dao Seed, he wanted to realize a new sword technique, so he didn't want to rely too much on the Dao Seed.

Ye Feng had just sat down, the ground suddenly shook, and then, the rocks bulged and turned into ten stone figures.

Looking at these ten stone figures, Ye Feng couldn't help but feel numb in his scalp and hurriedly got up. As soon as he got up, ten stone men besieged him, attacking wildly, and the deafening sound of collision echoed in the cave again.

Three and a half hours later, Ye Feng finally killed ten stone figures, and he supported his body with a wooden sword, so that he did not go soft to the ground.

The word "one" can control the power of one's own body and burst out with unparalleled potential...... Could it be that this sword has something to do with the word potential?"

Ye Feng took a deep breath and muttered to himself, he had already had some comprehension of the fourth sword, but unfortunately he was still a little missing, so he didn't create the word sword.

He made the blood flow in a spiral, creating the first sword, the sword of defense.

He compressed his blood qi into silk and created a second sword, the Sword of Extreme Speed.

He manipulated his blood and qi to transform into a dragon and created a third sword, the Sword of Bravery.

In the fourth sword, he thought of the potential to stimulate the blood qi, so that the power of the blood qi exploded instantly, and then the power of the sword qi also increased.

Just as he imagined the fourth sword, the ground shook, the rocks bulged, and a huge stone man twice as tall as the previous stone man formed.

Shiren strode towards Ye Feng, covering the sky with his big hand, grabbing Ye Feng like lightning, and the wind was blowing.

Ye Feng's eyes lit up, and he hurriedly moved sideways for more than ten zhang, avoiding the attack of the stone man.

The stone man turned around like lightning, stretched out his hand and slapped Ye Feng again, his big hand was like a fan, and the storm was everywhere he passed, and the sand and stones were splashing.

Ye Feng pointed to the ground with his toes, swept to the stone man's arm with a swish, stepped on the stone man's arm, rushed towards the stone man's head, and a sword shot out, the sword qi filled the sky, turning into a sword flower and shooting towards the stone man's head, where the sword flower passed, tearing the air and sparks flying.

"Boom!"

The sword flower exploded, the sword qi flew in all directions, and the terrifying explosion force blew the stone man's head to pieces, and the sky was full of rubble.

Ye Feng stood on the shoulder of the stone man, looked at the wooden sword and said to himself: "The fourth sword of the nine swords of the human rank, it's called the Sword of Explosion!"

In the face of the stone man's attack, he finally created the fourth sword of the human rank nine swords! Unfortunately, he still did not learn to kill the thirteen swords, the twelfth sword, and the thirteenth sword.

"That's all for today, continue tomorrow, let's go......" The middle-aged man's indifferent voice suddenly came from the stone house.

"Senior, junior has said goodbye!" Ye Feng glanced deeply at the stone house and turned to leave.

Half an hour later, Ye Feng broke out of the Mochou River.

Soon, Ye Feng returned to the room, he sat cross-legged on the bed, and asked, "Narcissus, who is that old-timer, and why can he control the wooden sword?"

"I don't know ...... either," Heavenly Demon Narcissus said, "That person is terrifying, I can't see through him." ”

"When I was fighting with the stone men just now, I found that those stone men had the aura of the Dao Seed on them. Ye Feng groaned: "If I guessed correctly, that old-timer also has a Dao species, I can't guess what kind of Dao it is, can you guess it?"

"I can't guess, but one thing is for sure, that person should have a natural rock Dao species. Heavenly Demon Narcissus said.

"Not only is his strength unfathomable, but he also has a Dao Seed, who locked him under the water?" Ye Feng suddenly frowned.

"If you want to know, it will tell you, so why bother yourself?" said the Heavenly Demon Narcissus.

Ye Feng smiled when he heard this, didn't think about it anymore, and fell asleep on the bed.
