"What's wrong?" Bai Yuhan's fingers suddenly stopped, and he stared at it.

"This stone is so weird. Chu Chen's surging heart instantly quieted down, staring at a strange stone not far away, his eyes not moving.

The sword just now was a dancing sword, and the killing machine was not sharp, and it was split on this stone, although it would not break, but the sword marks should at least be left.

However, the sword slashed down, leaving nothing but a string of sparks.

Chu Chen took a few steps forward and saw more clearly.

"Sure enough, my sword didn't leave a mark on this stone, it's strange. ”

"This stone is an extraterrestrial meteorite, put here for many years, according to my father, it was when he went out to travel, and accidentally found that it was a meteorite that fell from the nine heavens, my father felt that it was not simple, so he brought it back, but the daily research, in addition to finding a hard texture, but found nothing, and then was abandoned here, as an ornamental stone. ”

"Extraterrestrial meteorites. Chu Chen whispered, this stone is really not ordinary.

But it seems to ......

"Did you find something?" Bai Yuhan asked in a low voice, looking at him with surprised eyes.

Chu Chen didn't speak, holding the Purple Thunder Sword in his hand, and slashed over again.

This sword is not powerful, even very slow, much weaker than the sword just now.

"Sonorous!"

The blade of the sword quickly slashed at the extraterrestrial meteorite.

"This is..."A hint of strangeness appeared in Chu Chen's eyes.

He spread his soul power and found that when the sword slashed against the boulder, it produced a strange shock, but it was too weak.

"Sure enough, there is a mystery. ”

Chu Chen slashed away with another sword, this sword, full of power, brushed through the void and made a whistling sound.

"Khooth!"

After a burst of sparks, Chu Chen immediately closed his eyes and carefully felt the trembling power.

"Buzz"

In his mind, there was a sudden sound of a sword.

"On the extraterrestrial meteorite, there is a tremor force. Bai Yuhan also found a problem and couldn't help but scream.

This stone, which has been placed here for many years, has not found this, and when the long sword is slashed on it, there will be a strange tremor force, what is going on?

Chu Chen slashed twice more with the Purple Thunder Sword in a row, but there was no progress except for the strange sound of the sword in his mind.

"The sword power is not enough. ”

Chu Chen was surprised in his heart, the power of his sword was definitely more than 100,000 catties, but it was not enough to split on this stone mountain.

quickly put away the purple thunder sword, took out the black sword in a blink of an eye, clenched it in both hands, and slashed it down,

The strength of this sword has doubled, and the black sword itself is heavy, reaching more than 200,000 catties, which is extremely amazing.

At that time, when he broke through the eighth layer of the Blood Purgatory, he could even split the sword stone more than ten zhang high, which was like a small mountain, let alone this meteorite outside the sky.

The black sword slashed away, extremely fierce, and the stirring wind made Bai Yuhan slightly frightened.

A loud collision was followed by a spark like fireworks.

Chu Chen quickly felt the trembling sound from the meteorite outside the sky.

"Buzz"

In his mind, a sword roared, extremely loud, like a dragon roaring.

Between heaven and earth, it was as if a peerless sword was born, directly breaking the clouds and sky.

"Ahh

"What's going on?" Bai Yuhan exclaimed, quickly stepping forward to support him.

"What did you find, was there anything strange about that tremor force?"

Chu Chen didn't answer immediately, his head was really swollen, and it took a while before he recovered.

"What a sharp sword qi, such a domineering sword sound. Chu Chen blurted out directly, his eyes were full of horror, staring at the meteorite outside the sky, extremely shocked.

"Sword Qi, Sword Sound?" Bai Yuhan wondered.

"That's right, the trembling power, you should also feel it, the problem is there, the main sword power is enough, slashing on it, it will tremble out a more ferocious tremor power, and I feel the power, directly in my mind A sword sound, between heaven and earth, as if there is a peerless sword, straight through the clouds. ”

"A peerless sword comes to mind?" Bai Yuhan was surprised, but she tried, but she couldn't feel it.

"To be honest, I have mastered the power of sound waves, and I can directly perceive any sound. Chu Chen saw her doubts and explained.

"I see, you have mastered the power of nature so quickly. Bai Yuhan was amazed, Chu Chen was mysterious, beyond her imagination.

The extraterrestrial meteorite, which was recovered by his father and studied for several days, found nothing, and was abandoned here as an ornamental stone, but he never thought that by coincidence, Chu Chen discovered the mystery.

"This extraterrestrial meteorite is not simple, and I can let the president come over tomorrow to take a look. Chu Chen said, although he really wanted to understand the mystery, but after all, this was someone else's thing, not his.

"My father didn't find anything when he studied thoroughly, even if he now knows that this stone is not simple, he can't start, after all, he needs a person with a sword to understand, and the most important thing is to master the power of sound waves, this opportunity is destined to belong to you, you don't have to think about it, feel at ease. Bai Yuhan smiled and shook his head.

"In that case, then you're welcome. ”

Bai Yuhan is telling the truth, the power of trembling can only be perceived through sound waves, and the person who masters sound waves, he should be the only one in the entire Free City.

No matter how high a person's cultivation is, he is helpless in the face of extraterrestrial meteorites.

Chu Chen was not a hypocritical person, so he immediately slashed it with a black sword, and this time, the strength was much smaller.

The sound of the sword roared as if it was about to break his head, and he didn't dare to use all his strength anymore, for fear that he wouldn't be able to stand it.

Seeing this, Bai Yuhan didn't bother Chu Chen, and left silently, she was also quite looking forward to Chu Chen being able to penetrate the mysteries and see what was hidden in the meteorite outside the sky.

Chu Chen used the black sword to slash out the trembling power, and immediately felt the sound waves, and a picture directly appeared in his mind.

An open world, a sharp sword, blooming endless killing machine, very sharp, the sword is hundreds of zhang longitudinal, shocking the heart, a sword splits out, breaking the clouds.

This kind of scene was too impactful, and Chu Chen's breathing became short.

Martial arts extreme, can anyone really be so powerful?

The swordsmanship is superb, it can split the sky, he can't help but feel excited, if he can do this, he is much more powerful than the Ling family Ye Lao.

Although it was only a picture, it contained endless impact, Chu Chen had already controlled the sword power very weakly, but the sword that turned into a sword in his mind was still terrifying, and his head was extremely painful.

"No matter how painful it is, you have to persevere, the extraterrestrial meteorite may contain peerless swordsmanship, if you can comprehend it, it is a great opportunity, and it will definitely help my lethality reach an unimaginable peak. ”

Every time he slashed out a sword, Chu Chen fell into a sense of understanding, and in his mind, he realized that the earth-shattering sword, a sword came out, the wind and clouds changed color, and the sun and the moon were destroyed.

After repeating this, ten days had passed in the blink of an eye, Chu Chen had completely sat down, no longer slashing with the black sword, he had already established a mysterious connection with the meteorite outside the sky.

From the meteorite, there are sword patterns rushing to the mind, never stopping, that picture, like eternity, repeated drills, heaven and earth nothing, a sword to break the sky.

"How is it, has he understood it thoroughly?" A hundred meters away, the president took Tong Lao and a few others to ask a servant.

"Hui Gui Gui, Chu Chen is not over yet, about three days ago, he put away his sword and sat there directly, not moving. ”

After Bai Yuhan told her father Bai Jingqiu about Chu Chen's discovery of the mystery of the meteorite outside the sky, Bai Jingqiu was very surprised, and in order to prevent anyone from disturbing Chu Chen's enlightenment, he directly blocked a radius of 100 meters, no one was allowed to approach, and someone was left to guard it.

In the past few days, he has come to see it every day and ask about the situation.

Back then, since the discovery of the meteorite outside the sky, he felt that it was not simple, but unfortunately he didn't study anything, but Chu Chen could understand the mystery, and he also looked forward to it, looking forward to what martial arts cultivation Chu Chen would get in the end.

"If he really understands it, it is estimated that his combat effectiveness will be directly raised to a very terrifying level. Bai Yuhan looked at it and whispered
