"Look!"

Chen Tiansheng said loudly, and after speaking, he threw a punch in front of him.

"Boom!"

With a loud bang, a three-meter-high rockery ten meters in front of it suddenly exploded.

Xu Nian and Chen Yao's eyes widened suddenly, and a look of disbelief appeared on their faces.

With that punch just now, Chen Tiansheng obviously didn't use his aura, how could he blast a rockery in the air?

"Do you see clearly?" Chen Tiansheng turned his head to look at Xu Nian and Chen Yao and said with a smile.

Xu Nian and Chen Yao both shook their heads.

I don't understand how Chen Tiansheng did that trick just now.

"In fact, it is very simple, whether it is a sword or a fist or a knife, it is a use of the power of heaven and earth, I just used the power of heaven and earth to form an oppression on the rockery, so as to completely crush the rockery. Chen Tiansheng explained with a smile.

"The power of heaven and earth?"

Xu Nian's face showed a contemplative look, while Chen Yao was still at a loss.

"In fact, it is still a little too early to tell you about the power of heaven and earth, now you are just just comprehending the unity of man and sword, and the triple realm of the unity of man and sword, you have not yet comprehended, when you comprehend this triple realm, you will also understand what is the power of heaven and earth. Chen Tiansheng continued.

"Is there a triple realm in the unity of man and sword?, which triple is that?" Chen Yao asked.

Xu Nian also looked at Chen Tiansheng, this was the first time he had heard of such a statement.

"The three realms in the unity of man and sword are the sharp sword cutting hair, the wooden sword cutting stone, and the sword breaking gold. Chen Tiansheng said with a smile.

"Uh? This is not difficult? Isn't it easy to cut hair with a sharp sword? There is also a wooden sword to cut stones, as long as you reach the level of the Battle Sect, you should be able to do it, as for the sword to break gold, it doesn't sound so difficult. Chen Yao said.

Xu Nian shook his head, this triple realm may not be as simple as Chen Yao said.

First of all, the sword cuts the hair, not the hair, which means that the hair should be cut horizontally with the sword, and if you want to do this, the sword must be extremely fast, incomparably accurate, and incomparably ruthless.

Secondly, this wooden sword cutting stone is not so simple.

First of all, the wooden sword can't be infused with aura at all, because the wood is too soft, once it is poured into the aura, the wooden sword will burst, so the wood is used to cut off the stone, which requires an extreme grasp of the strength in the body.

One more is more, and one less is less.

It's almost hard to control!

As for this finger sword breaking sword, wanting to cut off the metal with his fingers, this is almost impossible in Xu Nian's opinion.

Even if the Battle Sect could use his fingers to stimulate the sword qi, it would not be able to maintain the sword qi at all, let alone cut off the metal.

These threefold realms, no matter which one of them, are not so simple.

"Uncle Chen, can you show us this?" Xu Nian said.

"Good!" Chen Tiansheng smiled.

After speaking, he took out an ordinary black iron sword, and at the same time tore off a hair and threw it in the air.

Then Xu Nian only saw a sword light flash away, and then a one-foot-long hair in the sky split in two and was cut into two one-foot-long hairs.

Xu Nian was horrified in his heart, he had already urged the dragon's eye and spiritual sense just now, but even so, he could only vaguely see the trajectory of Chen Tiansheng's sword swing just now.

"Is this a sharp sword cutting hair?" Chen Yao's eyes widened, and at this moment she finally understood how stupid she was just understanding.

Then Chen Tiansheng picked up a branch in the courtyard, and a soft aura emanated from him, completely enveloping the branch in his hand.

Under Xu Nian's dragon eyes, Xu Nian could clearly see that Chen Tiansheng's aura covered every part of the branch, and even the subtle textures on the branches were exactly the same.

"Buzz!"

The next moment, Chen Tiansheng waved the branch in his hand, and the bluestone slab on the ground was directly cut out of a long sword mark by the branch covered by the aura.

"What a terrifying control. Xu Nian said in horror.

To do this, you must be extremely familiar with the sword in your hand, and let your aura be completely integrated with the sword in your hand, so that you can exert super combat power, and the aura will not waste a single point.

Chen Yao was also dumbfounded, she asked herself if she couldn't do this.

"The last refers to the sword breaking gold, the gold here refers to the gold coin, the hardness of the gold coin is between ordinary iron and dark iron, so it can be cut off by the aura. Chen Tiansheng smiled, and a gold coin appeared in his hand after speaking.

Then a sword qi erupted from his other hand, and this sword qi actually condensed into an entity, forming an incomparably sharp sword blade.

Chen Tiansheng waved his finger sword, and the gold coin was cut by the finger sword, and the cut was extremely smooth.

Xu Nian was dumbfounded for a while, he didn't expect the sword to be able to be used to such an extent, and it was not an easy task to make the sword condensed by the aura reach a level comparable to the Xuantie Sword.

In the past, his understanding of the unity of man and sword was too narrow.

"Haha, what's the matter, now do you understand, in fact, the real unity of man and sword is to do the heart and sword, qi and sword, intention and sword, and then you will understand it yourself, I will take care of the invincible. Chen Tiansheng laughed.

After speaking, he walked out of the backyard directly, leaving Xu Nian and Chen Yao.

When Chen Yao saw his father leaving, he took out his sword and began to try to swing his sword to cut it.

However, her eyes couldn't keep up with the speed of her sword at all, and no matter how much she swung her sword, it ended up crooked.

Xu Nian didn't rush to try, but sat there quietly, thinking about every detail of Chen Tiansheng.

Time flies quickly, Chen Yao has practiced hundreds of times, but she can't even find the ends of her hair.

And at this moment, Xu Nian, who had been sitting still, stood up and started his first attempt.

"Whoosh!"

Xu Nian swung his sword like an afterimage, and a hair was cut in an instant, but the length was not equal.

It turned out that although Xu Nian cut the ends of his hair, he failed halfway through.

But just like this, it still made Chen Yao's eyes on the side stare like a cow.

She practiced here hundreds of times without touching a single hair.

This Xu Nian is good, just sitting for a while, and he is directly half of the success.

However, Xu Nian was extremely dissatisfied, at that moment just now, he used the eye of the dragon, and he was able to capture the trajectory and end of his hair in an instant, so he could cut it with a sword.

But in the middle of the game, he couldn't get the sword to cut it in half along the path of his hair.

"No, not by the eyes, but by the heart, the heart and the sword are combined, and only by the heart can the sword be perfectly cut. Xu Nian suddenly thought of what Chen Tiansheng said when he left, and immediately realized that his use of the Dragon's Eye just now was wrong.

So this time, he reined in the eyes of the dragon and completely relied on his heart to control the sword in his hand.

Of course, the final result was obviously Yi Jian, he failed, and he didn't even cut the tips of his hair.

"Cut, it turned out to be just luck, it scared me, I really thought you could understand it at a glance. Chen Yao muttered, and her heart instantly balanced a lot.

Xu Nian shook his head helplessly, this time he simply closed his eyes and let his mind completely merge with the sword.

"Buzz!"

Xu Nian opened his eyes suddenly, his eyes sharp.

Swinging his sword again, the blade slashed through the void.

A foot-long hair was cut in half by him.

"This ...... How is this possible?" Chen Yao on the side opened his mouth wide and froze in place.
