After a night of strolling around with Lin Wu, Yu Yan came to his residence.

Because there is nowhere to go for the time being, the place where Yu Gen lives is Lin Wu's house.

After closing the door, a hint of complexity flashed in Yu Yan's eyes, and he came to the table and sat down.

"According to the introduction in the book, this supreme heaven is full of immortal qi, and this immortal qi is similar to aura and xuanqi, but compared to the latter two, the qi of immortal gang is much more advanced. ”

Yu Yan muttered, his eyes flashing with spiritual light. He felt that under this immortal qi, his strength and cultivation were gradually sublimating and transforming at a slow speed.

Then Yu Yan came to the bed and sat down. A flash of excitement and anticipation flashed in his eyes, and after exhaling a cloudy breath, he slowly closed his eyes.

The next moment, when Yu Gen opened his eyes again, he had come to a vast space.

"This ......"

Yu Yan looked at the scene in front of him, and couldn't help but widen his eyes, his eyes were full of shock, "Is this my sea of knowledge!"

In this vast space, there are dazzling purple lights everywhere, and these purple lights look dense, like silk threads.

These purple lights exuded a vast and terrifying sword intent, just like the space of the sword, and these sword qi turned out to be purple.

"The mystery of the sword!

Yu Yan felt a little unbelievable at this moment, before he only had the mysteries of the ten swords, but now the entire space was filled with purple sword lights, these purple sword lights were undoubtedly the mysteries of the swords, but the number of swords now was beyond his imagination.

"Ning!" Yu Yan couldn't help but snort softly.

The space surged, countless purple sword qi instantly condensed, and a huge figure ten zhang tall and emitting dazzling purple light suddenly appeared behind Yu Qian, this huge figure was the same as Yu Qian's sword body!

"Such a terrifying coercion, with this move, you can be on par with that demon immortal ancestor!" Yu Yan was shocked in his heart.

Before, he also successfully fused the mystery of the sword into his sword body, and the sword body also emitted purple light, but compared with this time, it was simply a small thing, not at the same level at all, which was equivalent to the gap between children and adults.

At this moment, Yu Qian's sword body was even more solidified, and the aura emitted was even more terrifying.

"I didn't expect that after being dissolved by the Demon Immortal Ancestor, I was blessed by misfortune, and the mystery of my sword has undergone a transformation again!" Yu Yan raised the corners of his mouth, revealing a happy smile.

Previously, it was all formless sword qi, solidified with his forbidden energy, but now all his sword qi is the mystery of the sword, and the mystery of the sword can be said to be the highest manifestation of the way of the sword.

In addition to being shocked, Yu Yan also slowly raised his head and looked up, and sure enough, under this look, he couldn't help but tremble, and a trace of complexity flashed in his eyes.

At this moment, the figure of the Supreme Fortune was no longer visible above his head.

"Before, I tried every possible way to drain Yun Bo out of my own sea of knowledge, but at this moment, when Yun Bo really disappeared into the sea of his own consciousness, he was a little uncomfortable. Yu Yan showed a meaningful smile, helpless and relaxed.

In the following days, Yu Geng's Yuan Shen comprehended swordsmanship in the sea of knowledge, while his physical body was quietly absorbing and refining the immortal qi of this supreme heaven in the outside world.

However, if you want to refine the Qi of Immortal Gang, it is far more difficult than banning various spiritual powers such as energy and Xuan Qi, so this time it took a whole year to close the matter.

During this period, knowing that Yu Yan was in retreat, Lin Wu didn't come to disturb him.

This day, early in the morning.

A terrifying sound instantly sounded from the wooden house, and then the entire wooden house was instantly twisted into powder by purple sword qi.

This earth-shattering noise naturally reached the ears of all the villagers in this mountain village, and the first to hear it was Lin Wu and his mother.

As soon as the two of them came to the wooden house, looking at the wooden house that had been twisted to smashes and the white-clothed figure sitting in the void surrounded by a cloud of purple sword qi, they couldn't help but widen their eyes.

This......

"What a terrifying sword qi, I'm afraid that every sword qi can easily kill me!" Lin Wu's eyes widened and he muttered, his eyes full of shock.

Looking at the white-clothed figure surrounded by clouds of purple sword light, Lin Wu couldn't help but clench his fists, and an excited light flashed in his eyes, "If you can exert such momentum and coercion, Brother Yu should have broken through." ”

At this moment, next to Lin Wu and a woman, the space fluctuated for a while, and then I saw a white-haired old man in cloth clothes appear.

As soon as Lao Tzu appeared, when he looked at the figure in front of him sitting in the void and surrounded by Dao Dao purple sword qi, he couldn't help but be startled, his eyes were full of shock, "Dao Realm." And he also comprehended the mystery of the sword, but so many swords are really unheard of!"

"Village Chief!" Seeing the white-haired old man, Lin Wu and the woman both said respectfully at the same time.

It turned out that this old man was none other than the head of this village.

The old man nodded slightly, then looked at the tall Lin Wu, and immediately said, "Yu Xiaoyou is now in the breakthrough period, you first disperse the villagers so as not to be injured by the sword qi." ”

Looking at the purple sword qi that sounded with the sound of breaking the sky, a trace of jealousy flashed in Lin Wu's eyes, and he quickly nodded, then turned his head and walked towards the villagers who were rushing behind.

"Village Chief, this won't be anything wrong with the children, right?" asked the plainly dressed woman on the side, her tone full of worry.

Because there is a possibility of failure and success in cultivating to break through every major level, and even there is a danger to life.

"Seeing that Yu Xiaoyou has accumulated so much, breaking through the Daoless Realm will be nine out of ten, and nothing will happen. The white-haired old man nodded affirmatively, although he was only in the early stage of the Daoless Realm, he had been stuck in the Daoless Realm for a long time, and he naturally had some understanding of the Daoless Mirror.

Hearing the old man say this, the woman couldn't help but breathe a sigh of relief.

As the old man spoke, a thought flashed in his eyes, and then he waved his hand.

A wave of invisible energy suddenly appeared, and it was about to go towards Yu Qian.

However, the next moment, what the old man never imagined was. As soon as his energy came into contact with the purple sword qi surrounding his body, it was instantly pierced and shattered.

What! The old man's face changed slightly, and he couldn't help but be startled.

"What a terrifying sword aura!" the old man was also shocked for a moment.

At this time, Lin Wu also came, looking at the old man's face a little pale, he couldn't help but ask worriedly, "Village Chief, what's wrong?"

The woman also looked at the old man worriedly, and the old man waved his hand, "I originally wanted to shroud and protect Xiaoyou, but I didn't know that the sword qi around him was so terrifying and domineering, it seems that there is no need to worry about anything." ”

Yu Gen only felt that he had entered a very mysterious state at this moment, and after a year of accumulation and refining, he had successfully fused the forbidden energy with the Qi of Immortal Gang and the mystery of the sword. And at this moment, the terrifying purple light around him was his subconscious protection for himself.

After using the Transformation Yuan True Method to fuse these three seemingly different energies, the essence of which was the same, Yu Yan felt that his power had undergone a metamorphosis again.
