What is sword intent? It is not a perceptible Xuan power, nor is it a sword qi that is sharp and has thousands of forms, nor is it a Xuan Jian that can be transformed into a substance, but a kind of Xuan Jian mystery that cannot be seen or touched.

This kind of mystery comes from the talent of the sword source, which is very valuable, and it is an increase and attribute blessing for the power of the sword.

The four sword intents that Gu Zheng has mastered now are all derived from his talent, which can be doubled in terms of rigidity and flexibility, explosiveness, strength, and speed.

This increase is terrifying, and its power increase is reflected in geometric multipliers. And this kind of thing that comes from talent can only be made up for by using natural treasures after it is missing, but it cannot be improved again on the original basis.

But Gu Zheng can now be said to have found another way, using the fusion between different Xuanjian sword techniques to achieve the mutual promotion and improvement of sword intent, directly doubling.

In other words, this move of the fusion of Firefall and Cloud Rain, the violent sword intent and the rigid and soft sword intent in it, after doubling the life, the power increased by two times, which is naturally not the same.

Gu Zheng has a feeling, this is not the limit of the fusion of the two, this fusion is not thorough and natural enough, but Rao is so, and the change in power is very terrifying.

The giant ape, which kept waving its eight arms and ascending into the air to pursue Gu Zheng, faced with this condensed and doubled Burning Mountain, it unexpectedly showed a rare sluggish color, its perception was also keen, and it had already felt a huge threat from it.

But Gu Zheng didn't just take out his sword and collide with it, this was not his limit, and it was not enough to kill this powerful fifth-stage giant ape.

The fusion of Burning Mountain and Yunyu, Gu Zheng can only do this step for the time being, but he also has two other swords, which can also be fused into them, making them qualitative again.

This kind of fusion can at least be achieved by swordsmanship, and only in the subtle realm can it be analyzed and then integrated.

Fortunately, Gu Zheng's other two major swordsmanship, the Fufeng Sword Technique and the Snow Dragon Sword Technique, have been mastered, so there are more possibilities.

"The wind is coming!" Another handleless flying sword beside Gu Zheng turned into a wisp of light wind and flew away, heading straight for the burning mountain.

The wind fuels the fire!

Gu Zheng blessed his soul, and saw that around the burning mountain, countless winds swirled in the end of the micro, constantly submerging into it, the flame of the burning mountain soared, the fire was fierce, and the sword intent rose again, with the fury as the most.

At this point, the three swords fused into one blow, and when the giant spirit ice ape saw this, he ran away, and there was no intention of fighting.

"It's too late to leave. Gu Zheng sneered, waved out the Huangchen Xuanjian in his hand, stepped on the dragon shadow, and rushed towards the whirring burning mountain.

The tornado reappeared, enlarging step by step, enveloping the entire Burning Mountain in the blink of an eye, and the speed increased again, and it contained four terrifying sword intents, staggered.

It's hard to say what other sword intents are, but the Burning Mountain Furious Sword Intent alone has tripled the explosive power of this blow.

This hit also contained the speed sword intent, and its sky-skimming speed increased even more, and it could not be compared to the speed of that giant spirit ice ape, let alone escape.

The giant spirit ice ape instantly realized it, and suddenly decided to live and die, so he wanted to turn around and blow up the inner pill, in a vain attempt to die with Gu Zheng.

The blow that swept through the four sword intent sword qi suddenly erupted with a piercing sword roar, and there was a faint terrifying sound of a tiger's roar.

As soon as this voice came out, the first to bear the brunt was the giant spirit ice ape, and the soul-intimidating power in it was no longer what it used to be, even the ice ape of the fifth stage of the ground level could not be spared.

The giant ape's eyes suddenly dimmed, and there was a moment of sluggishness, and that is, at this moment, the tornado had descended, enveloping it.

Heaven and earth seemed to be dead and silent at this moment, only the sound of the breeze was soft.

The loud sound also means that the control of Gu Zheng's blow is terrifying, and he will not spare any effort and take effect.

Rumble!

Finally, a roar resounded in all directions, the tornado dissipated, the fire and rain fell, the wind swept the clear sky, and only the straight and straight Qianzhang beast bones and a black-clothed figure were left in place.

Gu Zheng held the Huangchen Xuanjian in his hand, and the other three swords beside him were a little dim, his face was also slightly pale, and Zhihai was a little shocked.

This blow had already exceeded Gu Zheng's expectations, and the fusion of the four sword intents exploded, giving him the most powerful blow he has now.

This blow, which Gu Zheng called the wind and fire, meant the fusion of the four swordsmanship he had mastered now.

This blow also meant that Gu Zheng's strongest attack method was born, which was enough for him to kill the fifth rank of the ground level, and even threaten the beast clan powerhouses of the sixth and seventh stages of the ground level.

With a wave of his hand, he put away the bones of the giant ape and the beast pill, and Gu Zheng silently recovered in place for about a quarter of an hour, and that feeling of powerlessness eased a little.

This blow consumes the most soul and willpower, it can be said that there is no room for the slightest mistake, and the sudden relaxation after a high degree of tension makes Gu Zheng particularly tired.

"There is only the power of one blow, and if you miss a blow, you must flee away, otherwise it will be me who will die. Gu Zheng was secretly afraid, and at the same time reflected on his own body, he must not be negligent because of this victory.

"Moreover, this time, my fusion of the four sword intent sword techniques was still a little reluctant, and it did not achieve the best effect. If I am given enough time to figure it out, I will be able to follow the trend more smoothly, instead of forcibly merging and hurting the enemy and myself. Gu Zheng was still reminiscing about his bold move just now.

There is no doubt that this attempt was successful, but it was also extremely dangerous. Any mistake in any of them will lead to failure, and even hurt Gu Zheng's soul and devour his own body.

However, through this fusion, Gu Zheng figured out some of these tricks, such as the intolerability of water and fire, such as the wind fueling fire, such as the subtle use of the realm, and the indescribable connection between kendo, etc.

These all require Gu Zheng to temper and make bold attempts, which is not a day's work. The door was opened, but the contents of the door were still profound and infinite, and he needed to calm down and delve into it.

"The war on the mainland is also an opportunity for me to continue to hone my swordsmanship and understand the mysteries. Gu Zheng sat in deep thought above the clouds in the sky, and it was not until an hour later that he put away his thoughts and left.

The rebellion of the beast tide on the Taihu Lake, Gu Zheng calmed it down with the strength of one person, although there were some twists and turns, but fortunately, there was no danger, and after Gu Zheng passed the news to all parties, he no longer stayed.

In the next few days, Gu Zheng flew in all directions along the tributaries of Taihu Lake in all directions, looking for the strong man of the beast clan as his opponent, and continued to hone his way of sword fusion.

And as more and more earth-level beasts died in his hands, Gu Zheng's accumulated earth-shattering qi became more and more sufficient, and six days later, he broke through again, and the Thirty-Nine Xuangong reached the fourth order and fifth stage.

Gu Zheng was not in a hurry to break through the sword source cultivation, but continued to consolidate the foundation, hunting and killing the beast clans that were wandering all over the place, and the fusion of sword techniques became more and more proficient and natural, and the beast clan powerhouses of the fifth or even sixth rank of the ground level could also fight.
