After an unknown amount of time, Yi Yan's body suddenly shook, and a dazzling golden light emitted from his body.

The raging lava around him was pressured to a halt and helplessly stopped three feet away from Yi Yan's body. He was unable to advance another inch.

< p > "I've finally broken through!"

Yi Yan slowly opened his closed eyes and calculated that he had actually closed up for more than ten years already.

According to the records of [Nine Revolutions Indestructible Vajra Body], under the condition of having sufficient mental realm and energy, the first transition would usually take less than ten years to complete. With his current mental state which was far above his cultivation, it had actually taken him more than ten years to break through it, which made Yi Yan feel extremely surprised.

"Fortunately, we didn't miss the time. There are still three years left until the arranged battle."

Luckily, although he had trained for a long time, he was still within an acceptable range, so Yi Yan didn't think too much into it.

However, the Yi Yan now did not dare to continue cultivating, breaking through the first transition required more than ten years. If he wanted to improve, he would need even more time.

With his spiritual consciousness, Yi Yan realized that every part of his body was brimming with energy, and surging energy filled every cell.

Feeling the unprecedented state of his body, that feeling of fullness even caused Yi Yan to have an illusion, as if he did not need to summon any energy in his dantian.

The only thing he did not expect was that the energy contained within his body was not the power of the early Nascent Soul recorded in the [Nine Revolutions Vajra Body], but was far beyond this range.

However, Yi Yan had never cultivated any body tempering technique before, so everything he knew was learned from some cultivation techniques. In terms of words, understanding was not as profound as personally experiencing it, and in addition to not being able to fully utilize the energy within his body, he was unable to confirm his current state.

However, according to Yi Yan's experience, the energy contained within his body right now was already comparable to that of a Nascent Infant at the Awakening Realm in his previous life!

This point confused Yi Yan.

What Yi Yan did not know was that when he entered a deep meditative state and channeled [Nine Revolutions Indestructible Vajra Body] with all his strength, the Life And Death Taiji Fish that was rotating slowly in his sea of consciousness underwent some changes. A milky-white vitality flowed out from the [Taiji Fish], and following the circulation of the technique, it entered into the depths of every cell in Yi Yan's body.

His body and his internal organs seemed to have eaten stimulants after receiving the support of some living energy. The capacity of his body, which had already reached its limit, suddenly increased by a large amount.

This resulted in Yi Yan's physical body being much more powerful than ordinary cultivators after breaking through the first transition. Of course, it also took a lot more time.

Since he couldn't figure it out, Yi Yan didn't want to think about it too much. In any case, this wasn't the first time something unexplainable had happened to him since he started cultivating the Seal of Life And Death.

When his cultivation reached a certain level, there would always be a day when he would find out.

Yi Yan was suddenly stunned as he habitually inspected the situation inside his dantian.

Before he went into closed door cultivation, he had specially checked the status of the Taiji Fish. After absorbing the purple lightning from the Magic Array, the whirlpool above the Taiji Yinyang fish had stopped absorbing energy.

Now, after more than ten years of tempering, this energy had obviously reached its purest state. It was divided into two distinct colors, gold and silver.

These two powers intertwined with each other, sometimes crossing, sometimes parallel, and they were like two Flood Dragons encircling and dancing around the Taiji Yinyang fish.

With every revolution, there would always be a strand of energy that would be separated and injected into the Taiji Yinyang fish.

The golden energy of the Supreme Yang passed through the golden flame and poured into the tiny bit of the Supreme Yang Qi. At the same time, the energy of the Supreme Yang also entered the Yang Fish Eyes through the silver flame.

With the infusion of yin and yang energy, the size of the two fish eyes became larger and larger, while the speed of the yin yang fish also became faster and faster.

While he was paying attention to the change in the energy in his dantian, Yi Yan took out a portion of his spiritual sense to check his cultivation realm.

Sure enough, just as Yi Yan had expected, he was in the middle stage of the Aurous Core stage!

It looked like after more than ten years of closed door cultivation, not only had Yi Yan successfully broken through the first transition of《 Nine Revolutions Indestructible Vajra Body》, even his cultivation had unknowingly risen.

At this time, the amount of energy that had yet to be infused into the Taiji Yinyang fish Fish's eyes was very little. According to the current speed estimate, the process of energy fusion would be completed in less than a month.

There were still three years left, and Yi Yan was not in a rush. At a time like this, it was hard for him to calm down and do other things, so he simply concentrated on observing the changes in his Dantian.

One month later, as the last two strands of energy were injected into the Yin and Yang fish eyes, Yi Yan knew that a new change was about to occur.

Although he was in a state of spiritual perception, Yi Yan still subconsciously held his breath, carefully and quietly staring at the spinning Taiji Yinyang fish.

His body and the internal organs seemed to have taken a stimulant after receiving the support of a sliver of life force. The capacity of his body which had already reached its limit suddenly increased by a large amount.

Just as Yi Yan was about to lose patience and become anxious from waiting, the Taiji Fish suddenly shook, and the speed of its rotation gradually increased.

Although the increase in speed was small, under the observation of Yi Yan's spiritual consciousness, everything was revealed.

At the same time, the fish eyes that had grown larger after absorbing a large amount of energy suddenly began to spin instead of their usual calm state.

As the fish eyes rotated, streams of pure energy flowed out and merged into the Taiji fish.

However, the sunlight energy that had fused with the golden fish eyes had already turned into pure Lunar energy when it flowed out, completely merging into the silver half of the Taiji Fish.

The Grand Moon energy had also transformed into the sun energy, flowing out from the fish eye.

Unexpectedly, the two energies of yin and yang were able to transform into each other just by stopping by the fish's eye!

And following the continuous outflow of transformed yin and yang energy, the Taiji Fish's speed also started to increase by the second.

In the instant he witnessed the transformation of yin and yang energy, Yi Yan felt as if he had returned to the moment his soul was pulled out of the Spatial Channel. Two words inexplicably appeared in his mind: Old Yin gave birth to young Yang, Old Yang gives birth to young Yin.

Suddenly, Yi Yan was startled and understood what was going on.

Originally, only the purest and purest of Yin and Yang energy could transform into each other. He had originally thought that the energy that had been refined to the pinnacle in the whirlpool was actually far from the Yin Yang level, which was why he had to continue refining it outside the Taiji Yinyang fish.

When the energy outside of the Taiji Fish had reached its limit, it would then inject it into the Yin Yang Fish's eyes, using the Taiji Fish's continuous rotation to continue compressing and tempering the Yin Yang Fish's eyes. Every time a sliver of energy was completely refined, the fish's eyes would receive another wave of energy.

After going through the three procedures of tempering in the vortex, further tempering while coiling the Taiji Fish, and compressing at the fish eye, the gold-silver energy had reached a state of extreme yin and yang. Only by fusing with the Taiji Yinyang fish could it be transformed into the opposite!

This also reflected from one side how harsh the Taiji Yinyang fish's energy absorption requirements were.

In this instant of comprehension, Yi Yan felt that the entire world in front of him had changed. In the past, when he observed the Taiji Yinyang fish in his dantian, he always felt like he was seeing a flower through a fog. It was as if there was a thin veil covering his eyes, and the more he tried, the more he couldn't see clearly.

However, the process of the transformation of yin and yang energy was just like an incomparably sharp blade, piercing through this thin veil. The Grand Dao of yin and yang suddenly became clear in Yi Yan's heart.

Once again using his Spiritual Sense, Yi Yan was delighted to find that his cultivation had reached the late stage of the Jindan Stage.

Due to the extremely high level of energy in his body and its purity, under the control of his strong mental state, the fighting strength Yi Yan could display just by relying on the energy in his dantian was not any weaker than that of a late stage Nascent Infant.

Adding his tyrannical physical body into the mix, even if he met with cultivators in the mid to late stages of the realm, Yi Yan was still confident that he would be able to fight them.

At the same time, Yi Yan realized that at that moment, his mental state, which had already reached the peak of the middle stage of the [Body Fusion], had a new breakthrough. He had successfully entered the late stage of the Body Fusion.

It turned out that the yin and yang energy, as the energy in this world, was second only to the life and death energy. The way it revolved and changed just represented the primal principles of the universe.

Yi Yan had some sort of experience on this and his mental state had naturally improved.

He just didn't expect that the simplest and most commonly seen yin and yang energy in the universe would actually be able to produce such a change.

In his previous life, Yi Yan was the same as ordinary cultivators. He always thought that the more complex the energy was, the more advanced the energy would be.

His body and the internal organs seemed to have taken a stimulant after receiving the support of a sliver of life force. The capacity of his body which had already reached its limit suddenly increased by a large amount.

This unremarkable energy of the sun and the moon was the true origin of the universe.

At this time, Yi Yan suddenly felt a sense of joy, glad that he had always been unfortunate and unlucky, because it was this kind of misfortune that allowed him to have the chance to understand the essence of this world. Although he only barely understood it, exploring it after having a direction would still save him a lot of effort.

Yi Yan gently shook his head and retracted his thoughts. These were all future matters, it was still too early to think about them now, so he decided to do a good job before talking about anything else.

There was still three years of time before Yi Yan decided to refine a new weapon for himself.

The Tang Dao he had obtained from the Yi family's secret cave had already been handed over to his grandfather, Yi Zhao now that he no longer had a suitable treasure to use, the other treasures would not be a problem for him to use as transportation. But in the process of fighting against an expert, even a slight difference in strength could cause victory or defeat to be changed, so Yi Yan had no choice but to treat it with caution.

The environment of the crater of the volcano was clearly not suitable for refining magical equipment. If one was not careful, they would be affected by the earth's core fire.

After pondering for a moment, Yi Yan did not ride his sword and left, instead he jumped forward and released his flying sword, creating a big hole on the cliff face inside the volcano. Stone fragments flew everywhere and fell into the fiery red magma under Yi Yan's body, stirring up many waves of fire that melted in the blink of an eye.

However, Yi Yan acted as if he did not see it, the thousands of degrees of hot lava only left a few white marks on his tyrannical body, before it congealed into a solid and fell onto the ground.
