Half a day later, Li Changfeng had already flown away thousands of miles away, and he casually found a place to stop.

After flying with all his strength for most of the day, he was already exhausted, and the sword qi in his body was even more exhausted.

At this time, he directly took out a futon, sat cross-legged on it, and began to absorb the Heaven and Earth Yuan Qi to restore his essence and spirit.

And his mind was directly into the Divine Sea space.

This fight hit him too hard, and he was originally full of confidence, thinking that even if he couldn't fight, he would be able to get out of the way, but the truth was too cruel, and he almost died in the hands of the Ghost King.

"The Tongtian realm is really terrifying, unless I can break through to the realm of returning to the truth to have the strength to fight, I am not the opponent of the other party at all. This time it's lucky, and there is no danger, but next time you may not be able to escape. I'm going to improve my strength, I'm going to break through again. ”

In the Shenhai space, Li Changfeng sat quietly in the void, thinking about the various situations of the previous battle, and the more he thought about it, the more he felt the horror of the other party.

He left a trace of his mind in the outside world to control his physical body to absorb the vitality of heaven and earth on his own, and in the space of the Divine Sea, his spiritual body began to practice swordsmanship.

The spatial sword technique has been practiced over and over again, becoming more and more proficient, always approaching the state of perfection, and his sense of the power of space is getting stronger and stronger.

Before he knew it, he had begun to practice the enhanced version of the Piercing Sword again.

A sword stabbed out, and the five elements of qi around the body were all surging and instantly separated to both sides, as if opening the sky and splitting the earth, and time and space were struck by a sword A shocking crack.

Although this is in the Divine Sea Space, it is actually not much different from the outside world, and no matter how powerful it is here, it will not be much worse in the outside world.

For a month, Li Changfeng practiced for a whole month. Without eating or drinking, his body was motionless, and he had been practicing swordsmanship in the Shenhai space, and his physical body outside was also constantly absorbing the power of heaven and earth, transforming into sword qi to strengthen himself.

At this moment, his cultivation had reached the peak of his divine powers, and the Five Elements Sword Qi had risen by as much as thirty percent, but there was still some distance from the Returning to the True Realm, and he had not comprehended the method of fusion of the Five Elements at all.

One month in the outside world, it has been four or five months in the Shenhai space, but at this moment, his swordsmanship cultivation has made a breakthrough, and the space swordsmanship has been cultivated by him to the realm of Great Perfection.

Moreover, the Piercing Sky Sword was also cultivated by him to the realm of perfection, and it could be completely integrated into the spatial swordsmanship.

At this time, he suddenly thought: the root of the meaning of drilling the sky lies in the power of rotation, just like an electric drill, through high-speed rotation to achieve an indestructible realm. In this case, why don't I take its essence, remove its dross, streamline it, and only take its rotation power, instead of having to rotate the body as well, so that the natural sword speed is faster, and the energy consumption is relatively reduced, and it can exert more powerful power.

After meditating quietly for a day and a night, he began to practice the Piercing Sky Sword again.

At this time, his body was no longer rotating, but his mind controlled the aura to rotate on the sword body, and after a long time, he finally let the aura rotate, slowly rotating faster and faster, as if attaching a layer of rotating power to the sword body.

"Boom!"

In the Shenhai space, as he struck out with a sword, the void shattered, and in an instant, he cut out a spatial crack of nearly a thousand zhang, as if it directly penetrated the Shenhai space, with infinite power.

"Haha, sure enough, now this Diamond Sky Sword is a real Xiaocheng, and when it is unleashed, not only does the consumption decrease, but the power increases by three points. ”

Li Changfeng laughed wildly, knowing that he had found the right direction, his idea was really feasible, and now he began to continuously improve this trick to drill the sky.

In the blink of an eye, another month passed, and at this time, his Piercing Heaven Sword had also been cultivated to the realm of Dacheng, and his aura could be integrated into the tip of the sword in an instant, natural and smooth, like flowing water.

"Boom!"

The void was instantly slashed open with a crack of more than a thousand feet, and the terrifying spatial power overflowed from it from time to time, but the surrounding area was not damaged at all. This is the perfect embodiment of the mastery of power to the realm of perfection, and the energy is restrained and does not leak out at all, and it all explodes in an instant.

This sword slash has no amazing momentum at all, only fast, extremely fast, faster than thunder and lightning. At the moment of slashing, the power contained in the tip of the sword instantly burst out, like a volcanic eruption, the power was shocking, and even the void could not stop the edge of this sword.

After practicing in the Shenhai space for nearly a year, he finally reached the point where he is now, the Piercing Sky Sword is completely complete, completely integrated into the space sword technique, the breath is restrained, and the aura is hidden in the sword and rotates at a high speed, and it is not clear at all on the surface, however, when the attack is approaching, it suddenly bursts out, and the power is nearly twice as strong as before.

Honestly do the cohesion of one point, to break the surface, indestructible.

"Now that my swordsmanship has been mastered, it's time to find the other party to try the sword. ”

Li Changfeng muttered to himself, his mind instantly returned to his body, and he began to concentrate on recuperating his spirit.

As soon as the spirit and spirit returned to the peak realm, he was about to go to the ghost king to try his sword, and he had completely regained his confidence, believing that he could already resist the other party head-on.

An hour later, Li Changfeng was in high spirits, stood up, looked up to the sky and let out a long roar, the sound shook for nine days, and it was heard far away.

He stood in the air, staring into the distance, quietly waiting for the other party to arrive. He knew that the Shadow King would be able to hear his whistling and come after him.

Sure enough, half an hour later, a dark shadow in the distance rushed towards this side like a ghost.

"It's finally here, this battle, I want the other party to have a good experience of the new space swordsmanship. Li Changfeng's blood was boiling, and his fighting spirit was soaring.

Now, the artistic conception of Drilling Heaven has been completely integrated into his spatial sword technique, and every move can contain the power of aura rotation. Although his cultivation has not yet broken through to the realm of returning to the truth, his strength has changed dramatically, and he can kill himself two months ago with a single sword.

In the blink of an eye, the Ghost Shadow King arrived one mile in front of Li Changfeng.

"I've been waiting for you for a long time, and today I'm going to see if it's your fists that are domineering, or my sword is sharp. ”

Li Changfeng let out a long shout, jumped up, and quickly swept forward.

When he got close to the other party, he slashed out like lightning with a sword, his sharp edge was completely restrained, and there was no amazing momentum, the only bright spot was fast, very fast.

But with this seemingly ordinary sword, the Ghost King suddenly felt a tightness in his heart, he felt a hint of threat, and his face suddenly changed greatly, and if he wanted to, he directly attracted the power of heaven and earth to add to his body, and a fierce punch blasted out.

At this time, the Ghost King no longer dared to directly use his hands to make a hard connection, but instead punched with a dignified expression.

"Boom!"

The void exploded, and a thousand-mile-long spatial crack appeared in an instant.

Li Changfeng's sword exploded instantly, directly cutting through the opponent's fist, and the sharp sword qi even cut a bloody mark on the opponent's fist, which was deeply visible.

Both sides were shocked by the strong force of the other and flew backwards.

After a few breaths, the two sides looked at each other through the thousands of zhang spatial cracks, their expressions were extremely solemn, and no one took the lead in making a move, just waiting for the spatial cracks to dissipate.
