The bones of the ancient emperor contain not only an emperor's perception of the way of heaven, but also various memories of his cultivation path. From the foundation to the five yuan, every step of promotion in the middle is an incomparable wealth for anyone in the Immortal Dao.

Xu Lin is the step of destiny, he can find the scene of his promotion to immortality from the emperor's cultivation memory, as long as he calculates that scene, Xu Lin will be able to find his own way to promote to immortality. Tiangui can also see the scene when the Great Emperor was promoted to the realm of the Five Elements, and he can also know the way to this step after calculating. This is simply a living dictionary, whether it is Xu Lin or Tiangui, they can find what they need from it and get great benefits.

What Xu Lin needs is the experience of the step of immortality, what Taixu and the tiger need is the experience of the tenth step of the three flowers, and the rules of heaven are the experience of the eleventh step of the five elements, although they cultivate together, but from the light belt that connects themselves to the bones, after the divine thoughts have entered the bones, what they see is what they want and need.

At this time, in Xu Lin's thoughts, he saw the owner of this skeleton, an ancient emperor, who had been promoted to the step of immortality countless years ago. And what shocked Xu Lin was that when this ancient emperor was promoted to the step of immortality, there was a heavenly catastrophe that came.

The Emperor was nearly a hundred zhang tall, looked incomparably huge, shimmering with dazzling golden light, and held a giant axe almost twenty zhang long in his hand. He just stood under the Heavenly Tribulation, full of a momentum of looking at the sky, and more of an absolute domineering aura.

Looking at the sky, who would dare to be the enemy? Such a scene hit Xu Lin's heart hard.

The Ancient Emperor was crossing the Heavenly Tribulation, the Heavenly Tribulation of the Step of Immortality, countless golden thunderbolts poured out like rain, slashing on the Emperor's body, but even the hairs were constantly splitting. On the contrary, the Great Emperor roared, and the thunder falling in the sky was immediately dispersed, and then the Great Emperor rose to the sky, raised the giant axe in his hand, and slashed at the Heavenly Tribulation Great Array.

"Boom!" a sound like a drum beat sounded in Xu Lin's mind, and then Xu Lin saw a scene that he couldn't believe. The giant axe fell, and the sky was almost split in half in this axe, and the Heavenly Tribulation Great Array was in this axe, and the smoke and clouds disappeared, and all the formations collapsed, and finally could only dissipate into dust and smoke between heaven and earth.

"An axe split the Heavenly Tribulation Great Array, is this the growth history of a Great Emperor?" Xu Lin thought dumbfounded.

He had heard the Heavenly Rules say that among the twelve steps on the path of cultivation, only when the twelfth step was promoted would there be a heavenly calamity, and in the first eleven steps, it was all smooth sailing. But just now, he saw this ancient emperor, and when he was promoted to the step of immortality, a heavenly calamity came.

The gap between people is so obvious. Xu Lin only then understood why some people could become emperors, while some people, even if they had once been on the earth, were still only famous, not emperors admired by everyone. The Great Emperor, all the way to the Heavenly Tribulation cultivation, after enduring the inability of others, in the process of life and death step by step, can truly become the existence of the world, roaring and arrogant.

Xu Lin exhaled lightly, and at this time, the Ancient Emperor in his mind began to be promoted after he had survived the Heavenly Tribulation. At the same time, a large fragment of the law related to the step of the Mandate of Heaven to the step of immortality poured in like a tide, drowning him in it in an instant.

"The Emperor's promotion perception!" Xu Lin said lightly, and then his eyes closed and fell into the deepest comprehension. The perception of the emperor's promotion was like a vast ocean, and Xu Lin was wandering in it at the moment, absorbing it wantonly.

Inside the cave, the rules of time flickered, emitting very faint fluctuations. Xu Lin's body flashed with a faint golden light, and his expression was very natural. By his side, Tiangui's face was full of joy, his eyes were closed, and from time to time there were several tracks of heaven and earth wandering like small snakes on his body. And Taixu is a flat face, and the color of his body also has a faint golden light flashing away, but it is not very obvious. The tiger was also immersed in consciousness at the moment, the six wings on his back were shaking weakly, and the slightest wind was entwined and wandering in it.

The four people in the cave are absorbing as much as they can, and the inexplicable time rule has accelerated the flow of time here to fifty times. However, even then, they did not wake up so easily.

This time, maybe half a month later, or maybe two months later. Anyway, that's it, one day, two days, three days... A month passed.

Two months and ten days later, in the originally dead and silent cave, there was suddenly a very obscure mana fluctuation. This mana fluctuation is very obscure, very inconspicuous, and if someone is around, it may not be able to notice. This obscure mana fluctuation quietly moved in the cave until ten days later...

The obscure mana fluctuations finally erupted and roared at some point.

Xu Lin had the lowest cultivation among the four of them, and he was also a person who was easy to take a step forward. So after more than two months of comprehension, two years after Dongfuzhong, he was the first to start his promotion.

There are twelve steps in the path of cultivation, and each step of promotion is a qualitative change. Especially after the step of the gods, the steps of the gods began to contact the supernatural powers, the step of immortality began to contact the rules of space, and the step of destiny began to contact those mysterious forces between heaven and earth, such as fate, reincarnation, life and death. The step of immortality is the existence that can manipulate the rules of time, and the rules of time are cultivated to the extreme, evolving the Celestial Emperor Bell, and it is even possible to travel through time and space to kill the past and the future.

And only when we reach the step of immortality can we have the capital to stand on heaven and earth. Longevity refers to infinite longevity, a strong physical body, and the ability to live forever, but not to be immortal. But even so, the step of immortality already has the qualifications to cross the immortal path. Because of the step of immortality, he has already begun to come into contact with the rules of heaven and earth, which are known as the rules of all sources of all things in heaven and earth. Of course, the step of immortality is only contact, not mastered, only the eternal step can master this rule, so the eternal step is not only called the Dao King, but also called the Creator.

The Eternal Step was still too early for Xu Lin, and he had never had the idea of ascending to the sky in one step. Right now, what he cares about most is whether he can comprehend the rules of space to the limit when he is promoted to the step of immortality. To be honest, he had coveted the Universe Celestial Mirror for a long time.

In the cave, Xu Lin's sitting body suddenly hung in the air, floating in mid-air. And the band of light that had been connecting him to the bones suddenly broke off at this time. He can only receive so many benefits now, and any more will blow up his body and destroy all his minds.

In his body, Xihua True Jie operated on its own, and countless Xihua Divine Qi surged from the void, and the amazing purple qi filled the entire cave mansion in an instant, and an indescribable feeling emanated from Xu Lin's body.

In an instant, the essence of Xu Lin's whole body had reached its peak. His cultivation instantly rushed to the peak of the Destiny Step Great Perfection, and then began to attack the Immortal Step.

Xu Lin opened his eyes, and after glancing at the Heavenly Rules, his body moved, and he was drawn into a ray of light in the same place, and his body disappeared into the cave, and the next moment he was already standing on the top of the mountain where their cave was located. Before Xu Lin could fall to the ground, a terrifying mana surged up in his body.

His mana has always been a combination of Xihua Divine Qi, Infinite Sword Yuan, and so on, so when the mana in his body began to surge now, Xu Lin's body immediately exuded a chilling sword intent, divine Xihua Purple Qi. These sword intents, purple qi roared out above the mountain peaks, and with unparalleled lethality, they slashed the surrounding trees to pieces.

Xu Lin was surprised in his heart, but he didn't panic at all. He quickly landed on the ground, straightening up, his hands in front of him, his eyes closed, and all thoughts in his mind. Suddenly, a surging tide flooded in my mind, and there were also streams of enlightenment of the Tao, of immortality, and of heaven and earth.

Knowing this time, Xu Lin knew why the Immortal Step would become a big threshold in the eyes of countless Heavenly Mandate Cultivators. In the step of immortality, the rule of time is a key, and another key is to establish a heart for heaven and earth, which is also known as the heart of heaven. This Heavenly Heart does not exist between heaven and earth, but will automatically appear above one's heart after being promoted to the step of immortality.

The heart of heaven is the key to whether you can see the Celestial Emperor Bell. Heaven and earth have no heart, and everything is always self-aware. Tianxin will exist from the time it appears after the promotion to the peak of the Great Perfection of the Step of Immortality. And after being promoted to the Eternal Step, the Heavenly Heart will automatically spread out to the entire Xuangong World, making the Xuangong World a real world that can only be dominated by oneself.

Understanding this key, Xu Lin was not afraid. Because he has found this key existence from the memory of the ancient emperor, and at the same time knows how to set up a heart for heaven and earth. At this moment, all he needs to do is to follow the original steps and step into immortality in one fell swoop.

As the sun set, Xu Lin stood on the top of the mountain, his clothes were windless and automatic, and the hunting sounded. When quantitative change causes qualitative change, everything will become easier. The benefits obtained from the memories of the ancient emperor allowed Xu Lin to complete a process of accumulation. He closed his eyes, feeling the increasingly turbulent mana in his body, and a shallow smile appeared on his face.

"Step of Immortality, I'm coming...!"
