C4 Void Mutation

Because there were very few cultivation rooms in the outer sect, in order to prevent people from using one for a long period of time, one person could only stay for three days at most. At the same time, they would also need to obtain a black card from Elder Yun.

The outer sect has a total of twenty cultivation rooms. As long as there were people inside, the door of the cultivation room would let out a faint glow, telling others that there were people inside. If there were none, then it would be dim.

He randomly found a practice room and inserted the black card into the slot. A faint glow appeared at the door and with a click, the door opened.

Yun Su pushed open the door and walked in. There were all sorts of defensive arrays placed around the cultivation room. This could not only be used for closed door cultivation, but also for testing the martial skills he had learned.

The various spirit inscriptions surrounding the cultivation room formed a small scale defensive array. This kind of array's defensive power wasn't strong, but it was more than enough to defend against attacks from outer court disciples.

After tens of thousands of years, all of the prosperous civilizations gradually disappeared. Even the formation itself had been weakened to the extreme. This profound defensive formation, in the eyes of others, was just like a weak hand that could not withstand a single blow. It was full of loopholes.

It had to be known that Yun Su had once belonged to the Buried Heaven Alliance. Not only was there an Immortal King, quasi Immortal Emperor, and also a Pill God, the Ancestor of the array formation was also the ancestor of tens of thousands of arrays. A mere array formation could cover the sky and the earth, it could cover the sky and the earth, and when a defensive array was activated at full strength, even a quasi Immortal would not be able to break through the ancestor's defenses.

Yun Su had also learned their secret technique from the ancestor of the Pill God Formation. Although he had not studied the tenth layer, he had also learned 99% of it. He had reached the level of perfection.

He sat on the stone bed with his legs crossed, beginning to practice the God Burying Art. The main body of the art was the source of the heavenly dao, ever since Yun Su tore it apart, the heavenly dao was missing, the spiritual energy was exhausted, the entire 3000 great worlds had fallen into a low state. Over the past millions of years, although the human race had flourished, their strength, their realm, had already started to drop slowly, because the spiritual energy left behind by the mainland was no longer enough for them to break through to a higher realm.

Only those powerful sects and ancient sects would use their great powers to confine their spiritual energy to the mountain gate and prevent it from leaking out. This was also the reason why the ancient sects were so powerful.

The Heavenly Energy was fused into Yun Su's body, forming a cultivation technique that was difficult to understand. It was a supreme cultivation technique with a faint amount of spirit energy attached to it, gushing into Yun Su's body crazily, causing the space around Yun Su to flicker.

The mysterious and mysterious Heavenly Dao's laws swirled around his body as the faint divine energy of Order poured into him. Yun Su closed her eyes and sank into the deepest cultivation.

As Yun Su was immersed in cultivation, the sky above the Ancient Texts Depository suddenly changed color and rolling clouds surged. The dense lightning was like numerous thunder dragons hidden in the clouds, and the terrifying pressure caused the entire Ancient Texts Depository to become oppressive, following which multicolored light shot out from the clouds, as if it was breaking through the heavens and earth, appearing from a million miles away in the starry sky. It was extremely mystical.

Elder Yun who was originally lying on the chair suddenly felt this scene, a look of astonishment flashed past his eyes, his figure flashed, and he instantly disappeared.

Violent spirit energy rushed into Yun Su's cultivation room like a raging river or a lake, constantly filling up the lost spirit energy in his body and fusing with the heaven's way source, making it more suitable for him.

Some of the disciples who had been cultivating in isolation opened their eyes and walked out. They stared in shock at Yun Su's cultivation room, this scene was too terrifying, the spirit energy within a radius of five kilometers had poured into the room, almost filling it up.

A figure appeared outside the cultivation room and when the crowd of disciples saw him, they all called out respectfully: "Elder Yun."

"Such a violent influx of spiritual energy and the sudden change in the situation are truly strange. Compared to the talents of the inner court disciples, their talents are several times more terrifying." Elder Yun's expression was strange as he looked at where Yun Su was training, and the shock in his heart surged like floodwaters.

"Some outer sect disciples are suppressing their own strength just for the sake of shocking the inner sect examination. It looks like another genius is about to appear. The heavens are blessing the Sky Cloud Martial School."

A strange expression appeared on Elder Yun's face as he thought about it. He immediately waved his hand. "Alright, there's nothing else, you can all go back now."

Some disciples still wanted to stay and see the disciple who had caused such a change, in order to get to know each other. However, after hearing Elder Yun's words, they could only nod their heads and leave.

Elder Yun looked deeply at the cultivation room Yun Su was in, and disappeared in an instant.

At this time, in a luxurious mansion within the outer sect, a youth sat cross-legged on a limestone. Although his eyes were closed, the aura that surged from his body made one not dare to look down on him.

A few figures appeared and quickly walked over. Ye Fengli slowly opened his eyes, glanced at them and lightly said: "Is there something you need?"

One of the youths nodded his head and said coldly, "Senior Brother Ye, something has happened. Li Changde is dead, and he was killed with a single punch from the outer sect's well-known trash, Yun Su."

"Oh?" Ye Fengli's eyes fluctuated twice as his profound light flashed: "Li Changde is at the 3rd level of the Elementary Martial Realm. That Yun Su, I think he is at the 1st level of the Elementary Martial Realm. He can actually kill Li Changde with a single punch?"

"Senior brother Ye, that's not the case. It's said that Yun Su's strength is at the fourth level of the initial realm, but he hid it. After Li Changde provoked Yun Su, he was caught off guard and died." The young man said again.

"Li Changde killed by trash, that's just a joke." Ye Fengli snorted coldly, "No matter what, Li Changde is still my man. If Yun Su killed Li Changde, then that means he does not give me face, go, tell Cheng De, kill Yun Che, make an example to make others understand."

Hearing Ye Fengli's words, the young man was stunned. Zhang Chengde was at the fifth level of the Initial Stage and had sent him to deal with Yun Su? Wouldn't that be using a bullknife to kill a chicken?

However, he didn't dare to say anything. He nodded and said, "Yes, Brother Ye."

Two days passed by slowly and Yun Su woke up from her cultivation. After two days, Yun Su had completely fused her Heavenly Dao Essence with her body and channeled it into her dantian.

As he punched out, the void trembled as sonic booms rang out. Terrifying Spiritual Aura erupted as it smashed into the defensive array. Ripples formed on the array and continued for a full ten seconds before it slowly faded away.

Rays of law and order appeared in his eyes, revolving nonstop, as if there was a great terror within. A faint divine light appeared, then disappeared, as if it had never existed.

When she saw this, Yun Su's lips curved up into a smile, and the aura around her instantly disappeared. A faintly discernible aura appeared from his body, it was leisurely and elegant, with a gentle feel to it.

There are a lot of impurities in the Scorching Tiger Bloodline, so after a step closer, I won't have much left, so I can't use any of the most powerful immortal abilities. It looks like I still need to find those powerful bloodline killers, preferably the ancient ferocious birds and ancient beasts, to devour their bloodlines. Otherwise, their bodies won't be strong enough. Yun Su thought.

"In the future, if I meet any Heaven's Pride with an innate bloodline, or ancient beast bloodline, I'm afraid that I'll be at a disadvantage. I'd better hurry up and try my best."

"The Sky Cloud Martial School is not far from the Black Stone City. When the time comes, I can go to the auction in the Black Rock City to see if there is any beast blood. If it doesn't work, I can make some pills to barter with."

Thinking about that, Yun Su immediately walked out of the cultivation room, holding onto the black card to find Elder Yun: "Elder, card."

Elder Yun looked at Yun Su and his eyes immediately lit up. After not seeing Yun Su for two days, he felt like he had become a different person.

If the Yun Su from before could be said to be a sharp sword that had revealed its edge, then the Yun Su now was a treasured sword that had covered up all of its edge, a simple and unadorned sword.

The aura on his body was faint and indifferent, like a sword immortal walking across a continent. This scene caused Elder Yun to be stunned, and he could not help but take a few more glances.

Putting the card away, Elder Yun muttered to himself for a moment and then said in a low voice: "If there is a strong enemy that cannot be defeated, you can hide in the Scripture Pavilion."

Hearing Elder Yun's words, Yun Su was stunned for a moment before turning around and leaving with a slight smile.
