The duel between their master and apprentice was also very amazing and terrifying, and the momentum of Ao Lingtian's punch seemed to be as powerful as swallowing mountains and rivers.

In the face of Ao Lingtian's fierce and powerful fist, Phantom Lao was holding his fighting qi attached to his palm, and he met Ao Lingtian's fist with one palm.

"Collapse Fist!"

When Ao Lingtian felt that the fierce power of the Shattered Star Fist was being dissolved by the Phantom Elder one by one, he instantly changed his strength, and a powerful dark power surged into his arm fist.

"Bang!"

The fists collided, and a heavy muffled sound spread, and the ground under the feet of the two of them instantly collapsed, and the phantom old man was knocked back for some distance.

"Appreciated!"

After the phantom old man was knocked back, he immediately opened his mouth to praise him, and then he flew out, his five fingers together like a big knife and slashed at Ao Ling Tian.

Seeing this, a smile curled up at the corner of his mouth, and then his eyes closed, and the direction of the Phantom Elder's attack appeared in his mind, and he closed his eyes to dodge.

"Bang!"

Phantom Elder's attack fell on the ground, and the ground instantly collapsed and burst open, and he also had a very relieved smile as he watched Ao Ling Tian dodge his attack like this.

"Your perceptual predictions are good, but there's a bit of a drawback!"

The Phantom Elder suddenly pinched the seal with one hand, and an orange fighting qi turned into a circle, locking Ao Lingtian tightly.

"Teacher, you still hide this trick?"

Ao Lingtian's hands were tightly locked, as if he was tightly tied by a rope that he couldn't break free.

"You can predict the future of the attack, but you're too confident!"

"Bang!"

As soon as the phantom old words fell, a punch suddenly fell on Ao Lingtian without the slightest force, and Ao Lingtian was immediately knocked down and flew away.

Ao Lingtian was sent flying out, and the locked circle of fighting qi also dissipated immediately, but there was now a trace of blood flowing out of the corner of his mouth.

"Is it a slight injury to take such a blow? It seems that his physical strength is already very strong. Phantom Lao looked at Ao Ling Tian and received a punch from him, still as if nothing happened, and he couldn't help but be secretly surprised in his heart.

The two of them had been fighting for a few hours or so, and Ao Lingtian was also exhausted, even the Phantom Elder felt tired.

The ground around here was even more cracked and collapsed by the battle between the two of them at this time.

After a period of time, he found that the nights here were much longer than those outside, and Ao Lingtian was now lying directly in one place and falling asleep.

However, suddenly, a thick aura of heaven and earth flew in with the residual aura of the emperor, and finally merged into Ao Lingtian's body on its own.

Ao Lingtian didn't know his situation at all now, only the Phantom Elder watched with a surprised look on his side.

"Boy, this is a gift for you!"

"Spread the ancient scriptures, remember the heart and mysterious, astronomical yellow law, ancient secret mantras, the avenue is alone, the heavenly way is impermanent, and the star avenue is the law!"

The phantom old man suddenly recited the magic formula, pinched the seal with both hands, and yellow runes emerged from his old palm, and finally entered on the forehead of Ao Lingtian.

The sleeping Ao Lingtian felt as if something was there, and the corners of his eyes twitched a few times, but he didn't wake up because of this.

"Comprehend the secret technique, and your rune power will not be worse than that of a teacher in the future!" the phantom old man looked at the sleeping Ao Ling Tian with a pampered face.

The aura of heaven and earth automatically drilled into Ao Ling Tian's body with the residual imperial aura one by one, and the fighting qi space in his body slowly expanded unconsciously.

Ao Lingtian slept for more than a dozen hours, and when he woke up, it was just dawn, and the night time here was twice as long as the outside world.

"I've broken through to the Seven-Star Celestial?"

"Hahaha!"

As soon as he woke up, Ao Ling Tian found that he had actually broken through to the Seven Stars Smell Qi Heavenly Being, and he immediately burst into laughter.

He didn't expect that he could break through himself by sleeping, and if he let others know about his breakthrough, he would probably vomit blood and die on the spot.

Many people don't know how long it takes to work hard to cultivate to break through themselves, and some people even have to cultivate for more than ten years or decades to break through to a star, and he fought against his master for a few hours, and then he broke through after a sleep, which is unimaginable.

But Ao Lingtian woke up and didn't feel that there was anything in his mind, the rune spell seal spell sutra taught by the phantom elder, he didn't know it now.

"Strive to continue to break through in a short time, and start cultivating right now!"

Phantom Elder began to prepare for battle again, and Ao Lingtian also smiled and nodded, just like that, he fought against Phantom Elder shirtless.

"The teacher won't keep his hands today, you have to be careful. Phantom Lao stroked his beard and said.

"Come on!"

Ao Lingtian's words fell, and the Absolute Emperor Fighting Qi on his body suddenly emerged, and the black Fighting Qi swept away, and the momentum was magnificent.

"It's very powerful, let's see how experienced you are. ”

"Whew!"

Seeing this, a flash of appreciation flashed in the phantom elder's eyes, and then he flew into the air with a loud roar, only to see him open his five fingers and slap it down.

Ao Lingtian's face was full of solemnity, he saw that the palm of the Phantom Elder was struck down with the power that even tore through the space, and the ground under his feet actually shook, and some small gravel kept rolling.

"Big Tone Thunder!"

"Boom!"

Ao Lingtian quickly pinched the seal with both hands, and a thunderous sound suddenly sounded in the sky, and when the phantom old man heard this thunder, he looked back at the sky, and as a result, a thunderbolt was blasting down on him at this time.

"Boom!"

The phantom old man broke through and teleported away like a ghost, easily dodging the Ao Lingtian's Great Sound Thunder Method.

However, a smile flashed across Ao Lingtian's face when he saw Phantom Dodge dodge his own Great Sound Thunder Method.

"Boom, boom, boom......"

The sky suddenly sounded with a continuous sound of thunder, and huge thunderbolts fell from the sky and thundered down, and hundreds of thunderbolts bombarded down towards the phantom old at the same time.

"The wind can change, the stars can move, the sky can change, the earth can move, the yin stops, and the yang moves!"

The Phantom Old Man suddenly recited the words quickly, and yellow runes suddenly appeared out of thin air in front of him, and then the yellow runes lined up in rows to form a huge shield around the Phantom Elder!

"Is this a rune wall?"

"No, how do I know it's a rune wall?"

When Ao Lingtian saw the phantom old man using the shield formed by the yellow runes to resist his own Great Sound Thunder Method, he blurted out the rune moves used by the phantom elder for some reason.

"I have a lot of rune information in my head, what's going on?"

At this time, the rune spell seal scripture taught by the phantom elder suddenly appeared in his mind, and there were so many that he could not imagine.

"Ling Tian, take a good look, runes can not only make people stronger, but can also be used to directly attack the enemy. ”。

The Phantom Elder sensed that Ao Ling Tian knew that he had rune information, and immediately shouted to him to pay attention to how he used it.

Hearing this, when Ao Lingtian looked up, his loud thunderbolt had been cracked by the Phantom Elder at some point, and he saw that there were yellow runes spinning around him.
