When the two of them arrived at the first door, a burst of murderous aura rushed towards them. Nie Feng felt that if the door was opened, a wave of blood would gush out.

Nie Feng endured the biting murderous aura and looked at the door. There were only a few words on the door: Killing Taoist technique, Xiao Zhuxian Sword Skill.

He was slightly stunned, looked at Ying Ling, then looked at the stone chamber, and said, "This should be the skill you want, go in."

Ying Ling did not get the joy of the peerless martial arts that came from the same source, but looked at Nie Feng worriedly and asked, "Where are you?"

"I'm fine." Nie Feng replied, "Don't there still be a few secret rooms?"

"It's really okay?" Nie Feng promised: "It's really okay. Even if I can't find a solution here, I won't be fine."

If he couldn't find a solution, he would choose to be reborn. It was just that he wasting a chance to be reborn so quickly, which made him really unwilling to accept it. In addition, the pain of Pangu's essence and blood transforming his body, he really didn't want to choose this path unless he had to.

"Go." Nie Feng said. He didn't want to expose the ugly appearance of rebirth to Ying Ling. Ying Ling gritted her teeth and looked at Nie Feng reluctantly for a long time. Perhaps he was moved by his sincere smile and put his hand on the door. She was about to push the door and enter, but she didn't want a light to light up under her feet and teleport her away.

After Ying Ling disappeared, the stone gate disappeared. A wall turned into a front of Nie Feng. Nie Feng couldn't help but feel speechless when he saw this scene, thinking in his heart: "How much does this senior like to use formations?"

"Ah!" A golden smoke emerged from his body. The severe pain made him scream in pain. He couldn't help but hold the wall with his right hand to prevent himself from falling because of the pain. "It seems that it's time to hurry up. If the other four stone chambers have a way to save me, but I don't stick to it, I'll lose."

He held the wall and staggered towards the second stone door. He saw that the stone door read: Fantasy Taoist Technique, Xiao Hunyuan He Luo Art. "No, next!" The third stone door read: Ti Xuan Shuangxu Technique, Xiao Twelve Du Tian Shen Evil Art.

"Only, this body refining technique is good, but it is useless to me. Next!" The fourth stone door reads: The first defensive technique, the Little Zhoutian Star Fighting Art.

Nie Feng no longer had any hope when he saw this. The records of these stone gates were definitely first-class exercises, but for his current situation, these high-level exercises were of no use.

But with the thought of gaining insight, he still walked towards the fifth stone gate. He wanted to see what skills could match this name and know that they were the skills evolved from the four ultimate formations of the prehistoric world.

After experiencing so much, he was 100% sure that the existence who established this ladder was definitely a formation master.

Nie Feng endured the severe pain and walked to the last stone door tremblingly. This door was very ordinary, unlike the previous doors, either murderous, unpredictable, or like the starry sky.

The door reads: The Heavenly Silkworm Transformation. There is no way to write about the technique. On the three words "The Heavenly Silkworm Transformation", there is a silkworm that is struggling to spin silk and cocoons. After seeing this technique, Nie Feng's eyes lit up suddenly. The Heavenly Silkworm Transformation is a technique that can be put to death and then live and then break and then build.

He was excited, but unexpectedly, in despair, there was a village where the willows and flowers were bright and bright. He encountered a method that could survive this disaster without Pangu's essence and blood. Nie Feng took a deep breath, calmed down his mood, and placed his right hand on the stone gate with his right hand on the wall.

The teleportation array under his feet lit up, and the light flashed, and Nie Feng disappeared into the hall on the thirteenth floor of the Xuantian Tower. The hall restored its eternal tranquility. After Nie Feng's consciousness blurred, he found himself appearing behind that door.

This is a small secret room. There is a square platform that is one person tall and half a meter long opposite the gate. There is a jade book on the platform, and an extremely complex formation is carved on the ground behind the platform. Nie Feng stepped forward and picked up the jade book. The jade book said the transformation of the Tian Silkworm.

He gently opened the Tian Silkworm Transformation, and a ray of light burst out from the jade book, illuminating the originally dim secret room like daytime. Then, a phantom of a Tai Chi Liangyi compass floating around him floated out of the jade book, as the martial arts said, after the innate original energy enters the body, it will be affected by the guiding force."

The Tian Silkworm Skill said that the guiding power transformed from the energy that erodes the body will affect the innate original power entering the body, thereby affecting the attributes of cultivating mysterious energy in the future. "But this speed is too slow. It will take five or six years to spread the innate original power throughout the body and complete the human cauldron at this speed."

Nie Feng was helpless, but he had no choice. From the message from Emperor Xuan, he knew that this level of skill must be completed in one go, unlike the skill below the Dao rank, which can be completed in several times.

He was bored and divided his consciousness into two. Part of his consciousness always focused on the innate origin energy entering his body and erased the will of heaven; the other part sank into the sea of ​​consciousness and learned the various knowledge that Emperor Xuan passed on to him, including formations, alchemy, weapon refining, etc. Of course, the most of them was formations.

Time passed by Nie Feng's study, and the golden evil power drawn out of Nie Feng's body was slowly turned into a silkworm cocoon, wrapping Nie Feng up.

This world is not a pyramid-shaped one, with the most small worlds, and then gradually decreases upward.

This world is diamond-shaped, with only one world at the top and bottom. The highest world is called the holy world. What is the lowest world called? It is not mentioned in the information, but it must be very stable to support the three thousand worlds.

The senior who created the Xuantian Tower called himself the Emperor Xuan. He came to the holy realm and mastered the master of the formation path, so his formation cultivation can also be ranked in the holy realm.

He would come to Xuan Realm because he was ordered by the Lord of the Formation and Taoist to join the Heaven-Slaying Team and seal the immortal heaven.

As for what the sky is, he did not explain in detail, but only said that they were a group of madmen who wanted to return the world to chaos. Their Tianshu team came to the Xuan Realm. After a lot of hard struggle, they finally sealed the sky in Tianzhu Mountain. After completing the task, they should have patted the butt and left to another world to seal the sky.

Unexpectedly, after seeing the Xuan Cauldron cultivation method created by Xuan Xiu in this world, Emperor Xuan actually gained insights and broke through the realm that he had not broken through for many years.

So Emperor Xuan left a clone of power in the Xuan Realm, established Xuantian Academy and Xuantian Tower, and transformed the four ultimate formations of the prehistoric world and created the four previous techniques that surpassed the heavenly level. Emperor Xuan called them the Daotian team to a top-level Zhongqian world called the Tianscan World, and saw with his own eyes that the strongest man in the world, Tianscan Emperor, evolved into a cocoon nine times into a cocoon and evolved into a prehistoric ancestor dragon, swallowing the sky and creating the technique that was created after swallowing the sky.

Then after countless modifications, he spent hundreds of thousands of years of hard work to create this set of Tian Silkworm Transformation. However, practicing Tian Silkworm Transformation requires self-destruction. From the beginning, Tian Zi Xuan was reluctant to spend countless time practicing cultivation, so he did not practice. And he was unwilling to have his hundreds of thousands of years of hard work in vain, so he put it in the Xuantian Tower.

The Tian Silkworm Transformation is different from the general practice. The general practice is to cast a tripod in the dantian, but the Tian Silkworm Transformation uses humans as a tripod. Moreover, the cultivation requirements of the Tian Silkworm Transformation are extremely changeable.

It wants to destroy its own dantian, and then introduce an energy with strong erosion ability, erode all over the body as a guiding force, guiding the innate original power of the cauldron to every part of the body.

However, energy with strong erosion power must be very lethal. It can survive until this force erodes the whole body and cannot die. There are only a few in the three thousand worlds.

But Nie Feng was right now by chance, but he was in line with this state. After digesting the information in his mind, a look of surprise appeared on his face and he thought to himself: "Haha, I didn't expect that Nie Feng would encounter such a good thing."

After Nie Feng struggled to enter the platform, the formation lighted up as soon as he entered the formation.
Chapter completed!
