My Optimized Immortal Life

It is not an easy task for Chen Qing to refine the essence of earth fire from the earth fire veins.

Although the Earth Fire Transformation Technique was deduced by him alone, and was derived by integrating and optimizing more than a dozen second-level techniques, the Essence of Earth Fire is, after all, a second-level spiritual material, and in terms of rarity, it can even be compared to some third-level spiritual materials.

After setting up the cave made of black stone, Chen Qing first meditated for several hours to recover all the lost magic power, and then began to try to refine the essence of earth fire.

He just practiced his skills, and the liquid magic power in his dantian immediately flowed out along the meridians. Under his manipulation, a fist-sized ball of earth fire was separated from the earth fire vein. This fist-sized ball of earth fire was abnormally bright, and it was mixed with a strong spiritual energy, which merged with it and was extremely difficult to separate.

The veins of underground fire appear to be shaped like magma, but they are actually not ordinary things, simply because the way they are formed is fundamentally different from magma.

Each earth fire vein has a unique source. This source is generally a fourth-grade earth fire source, which is a spiritual object born between heaven and earth. Such spiritual objects, under the erosion of time, will continuously assimilate the surrounding rocks or mineral veins, thus forming earth fire essence of only second grade, far lower than itself. However, this kind of earth fire essence is large in number, and will continue to extend to the surroundings, assimilating rocks and mineral veins. Finally, after thousands or tens of thousands of years, a earth fire vein will be formed.

What Chen Qing has to do is to extract the essence of earth fire again from the earth fire vein which has been downgraded.

This process is extremely difficult. Even though Chen Qing has already reached the foundation-building stage, he only meets the lower limit of refining.

It took Chen Qing three full hours to refine the fist-sized ball of earth fire separated from the earth fire vein. However, the earth fire essence he obtained in the end was only the size of a fingernail.

This speed is a bit low.

After three hours of non-stop refining, even though Chen Qing was a foundation-building cultivator, most of his magic power was consumed. He could only return to the cave and meditate on the cushion to recover the lost magic power.

Let’s try the effect of this earth fire essence first.

Chen Qing sat cross-legged on a cushion, holding a fiery red crystal the size of a fingernail in his hand. This was the essence of earth fire that he had spent an hour to refine.

With the activation of magic power, the essence of earth fire was immediately engulfed. Then Chen Qing took it into his own dantian and started to practice the secret technique of refining the essence of earth fire in the Earth Fire Transformation Technique.

Driven by his skills, the light red magic power continued to rotate around the earth fire essence that was only the size of a fingernail, causing it to gradually melt and turn into an extremely pure fire spiritual energy. It was refined by Chen Qing and condensed into magic power after circulating through his meridians. His magic power was therefore recovering rapidly.

Two hours later, Chen Qing finished his training and opened his eyes, his eyes full of joy.

When his liquid magic power entered the foundation-building stage, due to the effect of the foundation-building pill, it condensed into forty-two drops. He was only eighteen drops away from the minimum limit of sixty drops to break through the middle stage of foundation-building.

And now, after refining that piece of earth fire essence that was only the size of a fingernail, Chen Qing's originally depleted mana was not only completely restored, but he was also only a little away from condensing another drop of mana, breaking through his own mana limit and getting one step closer to the middle stage of foundation building.

This is just a piece of earth fire essence the size of a fingernail. If it were a little bigger, Chen Qing estimated that he could at least condense one or two more drops of magic power.

In three hours, a piece of earth fire essence the size of a fingernail can be refined, and a piece of earth fire essence of this size can allow Chen Qing to increase his magic power limit by several drops. Even if the spiritual energy required to condense a drop of magic power is dozens of times higher than before in the later stage of cultivation, it will only require Chen Qing to practice for a longer period of time.

A month passed quickly, and there was still no outbreak of the Earthly Evil in Tianqiong Valley. Chen Qing didn't know whether it was a change of luck or something else. Even the Earth Fire Vein he discovered showed no signs of erupting. This also allowed him to practice for more than a month and make great progress in his cultivation.

Inside the cave, Chen Qing sat cross-legged on a cushion and looked inward. He saw sixty-eight drops of light red liquid magic power suspended in his dantian.

This is the result of his one month of practice.

Sixty-eight drops of liquid mana have exceeded the minimum standard for breaking through the middle stage of foundation building, but this is only the minimum standard. According to the standard of the Earth Fire Transformation Technique, Chen Qing has to increase the upper limit of mana to one hundred and eight drops to reach the limit.

One hundred and eight drops, he still needs forty drops. In fact, it won’t take long, a few months to complete it. However, this is because of the help of the essence of earth and fire. If he relies on his own practice, the time will probably be extended to more than ten years.

The life span of a cultivator who has established a foundation can be two hundred years, but among them, not many can actually cultivate to perfection in establishing a foundation. The path to immortality is difficult. Even though Chen Qing has a golden finger, he was able to make such rapid progress in his cultivation only after he found the vein of earth fire and possessed the Earth Fire Transformation Technique, which can refine the essence of earth fire.

If it were other ordinary cultivators, unless they were like Xu Lingxin, who had earth spiritual roots and could absorb spiritual energy much faster than ordinary cultivators, otherwise when they reached the foundation-building stage, the improvement in their cultivation level through hard practice for one day would be less than one thousandth. If they wanted to break through to the middle stage of foundation-building, they would have to practice hard for more than ten years to accumulate enough magic power.

Chen Qing now has sixty-eight drops of liquid mana, so he can try out his innate abilities.

After all, although his cultivation has reached the foundation-building stage, his skills are still at the Qi-refining stage. If he accidentally encounters other foundation-building cultivators, it would be dangerous.

When it comes to the foundation-building stage, the power of second-level spells will also experience a surge. Since he cannot get a spiritual weapon, Chen Qing feels that he needs to optimize more than a dozen second-level spells to enrich his combat power.

He does it as soon as he thinks of it. His Earth Fire Transformation Technique integrates more than ten kinds of skills, and there are eighteen corresponding second-level spells. If he masters all these spells, then Chen Qing is not a weakling in the early stage of foundation building.

The first second-level spell, called Red Flame, allows foundation-building cultivators to condense a second-level spiritual flame, which is extremely effective whether used to fight against enemies or to refine weapons and pills.

Chen Qing emptied his mind and activated his innate abilities. A drop of liquid magic power in his dantian immediately disappeared. At the same time, the words about the red flame in his sea of ​​consciousness, followed by Chen Qing's spiritual consciousness, quickly came to the depths of his sea of ​​consciousness. Then, a picture appeared that Chen Qing could not understand, leaving him stunned.

Deep in Chen Qing's sea of ​​consciousness, the words containing the information about the Red Flame spell quickly merged and finally turned into a picture. In the picture, it was Chen Qing practicing the Red Flame spell again.

In that picture, everything around Chen Qing was gray, but he was extremely lively. He kept making out the spells related to the red flame with his hands and muttering something. Then a ball of red flame rose from his palm and then suddenly went out.

This is what a spell failure looks like.

Chen Qing knew this very well. It turned out that the memory that suddenly emerged in his sea of ​​consciousness came from this source?
