According to the practice method of "The Unformed Spiritual Light", Ye Chen absorbed the pure energy from the space and slowly introduced it into the Yuanhai of Dantian.

Suddenly, he was slightly stunned and found that the immortal energy introduced into the Yuanhai of Dantian was like a fierce horse that had been reincarnated, rushing through the meridians of his body, and then evacuated outside his body.

If Ye Chen had not been strong enough, he would have been torn to pieces by the raging immortal world energy. This energy would have been too cruel to be refined and absorbed.

"Of course you can't absorb the vital energy of the fairy world here." Zhizhi pondered for a while before saying, "These vital energy of the fairy world are Xuantian stone fetuses, using the 'visual energy of the vital energy of the great.', to separate the void and draw from the fairy world, which itself contains its will and spirit. Only it can absorb it, and others cannot refine it."

Ye Chen was not very depressed: "Sure enough, there is no shortcut to the road of cultivation. Otherwise, with such a massive amount of immortal energy, I can practice here for ten thousand years and become an immortal."

"You cannot absorb the vital energy of the immortal world, but this space also contains a lot of pure vital energy. These pure vital energy are contaminated with a trace of the vital energy of the immortal world, and their quality has been directly increased several times. Although it is gaseous vital energy, it is comparable to the liquid vital energy you collected from the pure Yang Xian Furnace."

Ye Chen nodded slightly. He urgently needed to improve his strength. He had five days left before the sect mission. He planned to improve his cultivation to the peak of the middle stage of refining light, and then see if he could break through to the late stage of refining light in one go.

The mind sank into the Yuanhai of Dantian, and the source fire flashed and appeared in the Yuanhai of Dantian.

"absorb!"

Ye Chen's mind moved slightly, and the source fire burst out with a terrifying suction force, which emanated from Ye Chen's body, swept the vital energy of the immortal world and the rolling vital energy in the space into Ye Chen's body.

Zhizhi stood up all of a sudden, and she felt a strong sense of crisis. There seemed to be an adult beast in Ye Chen's body, and a terrifying aura swept out.

The smoke around Ye Chen's body was hazy, covering his body. The vitality of the fairy world was like a long whale sucking water and was taken into his body.

These immortal energy are violent and fierce, containing the will and spirit of the Xuantian Stone Fetus. They are refined by Ye Chen and are resilient in Ye Chen, and they are rushing in his body, trying to stir out.

The transparent source fire threads without any impurities jumped, absorbing the rolling immortal world's vitality. The terrifying original power burst out, directly erasing the will and spirit in the immortal world's vitality.

Immediately, the immortal world energy that was like a galloping horse calmed down and was quietly refined and absorbed by Ye Chen's four Yuanli seeds.

Titicaca!

It was as if chaos had been opened up, and Ye Chen's dantian Yuanhai was shining with light, and the fifth false Yuanli seed was directly formed, which was just absorbing a stream of immortal world energy!

"The source fire is really incredible. It can really refine the vitality of the immortal world."

Ye Chen was ecstatic. Although he had long guessed that the source fire could wipe out the will and spirit in the immortal world's vitality, when it really became a reality, it was a bit difficult for him to control himself in his state of mind.

He used all his strength to refine the vital energy of the immortal world. Streams of soft vital energy of the immortal world were constantly sprayed out by the source fire, and then absorbed and refined by the Yuanli seeds.

Soon, the source fire gradually became dimmed, and there was a faint sign of being about to be extinguished.

"not good."

Ye Chen's expression changed drastically, and the source fire was the foundation of his foothold. In terms of the preciousness, ten intact pure yang immortal furnaces were not as good as that, so he naturally did not want the source fire to be extinguished and disappeared.

"My cultivation is too low now, and this trace of source fire is too weak to refine the immortal energy for a long time..."

He quickly found the crux of the problem. It was a pity that there was really no shortcut to the path of cultivation.

On this day, he did not use the source fire to refine the vital energy of the immortal world, and silently introduced other vital energy in the pure Yang Xianfu space into his body. The quality of these vital energy is countless times lower than that of the vital energy of the immortal world. However, because it is contaminated with a trace of vital energy of the immortal world, its quality is quite good. Ye Chen used the "Fairy-Wu Yin Light Mirror" method and felt that his cultivation has made rapid progress, and the fifth seed of vital energy tends to be full.

The next day, he once again used the source fire to refine some immortal energy. As soon as he noticed that the source fire was in danger of extinguishing, he immediately stopped.

Ye Chen warmed the Pure Yang Spiritual Sword in the Yuanhai of Dantian. Since the birth of this flying sword, it has been moistened by the vitality day and night. In the past two days, it has been washed away by the vital energy of the immortal world. Its quality has increased rapidly and directly increased to the peak of a top-grade spiritual weapon. As long as the spirit of the weapon reaches a perfect level, it can be directly promoted to a top-grade spiritual weapon.

There is only a line between the best spiritual weapons and the low-grade banned weapons. As long as the restriction is carved on the best spiritual weapons, it can directly transform and become a low-grade banned weapon.

"One hundred and one low-grade spiritual weapon, forty-one medium-grade spiritual weapon, twenty-one high-grade spiritual weapon, six superb spiritual weapon, and one low-grade ban weapon, all exploded for me!"

There were 186 magic weapons obtained from the fourteen storage bags. Ye Chen made up his mind this time, leaving only one low-grade ban weapon, nine excellent spiritual weapons, and all other magic weapons exploded, causing all the spirits to appear in the air.

There were 170 light balls in front of me. The most dazzling one was undoubtedly the low-grade ban weapon that was burst open by Ye Chen, which was as vigorous as a bright moon.

"The spirit of the weapon merges!"

Ye Chen's body squirted out, splitting it into 170 strands, holding all the spirits of the instruments and trying to merge them together.

The halo flashed, and the low-grade ban weapon spirit, which had already had a weak consciousness, was unwilling to be fused and was about to explode.

Seeing this, the other instruments also flashed with light and wanted to follow the example of themselves.

Where would Ye Chen make them happy? He opened his mouth and sucked it directly, and the Yuanli was swept and the sea was absorbed, and he took all the instruments into the Yuanhai of Dantian.

The source fire surged, wrapping all the instrument spirits one by one. Whenever it spit out a instrument spirit, it means that the consciousness of the instrument spirit has been completely erased and turned into a spiritual body without any thoughts, and can be controlled by others.

"This treasure of yours looks like the rumored treasure of origin..."

Zhizhi was also practicing, trying hard to refine the seal in her body. Her eyes shone with golden light, as if she could see through Ye Chen's Dantian Yuanhai.

Ye Chen was at this moment and had no time to pay attention to Zhizhi. He tried his best to merge all the spirits into a ball of light.

As soon as this ball of light was formed, it burst out with a bright light, like a fierce sun rising from the sky, and the golden light burst out even passed through Ye Chen's Yuanhai and burst out beyond his body.

Ye Chen quickly imprinted his spiritual mark on the light ball, and then pushed it into the sword body of the Chunyang Mind Sword.

There was a faint halo inside the Chunyang Spirit Sword, which was the weapon spirit of the Chunyang Spirit Sword. It was in a daze and was nowhere much bigger than soybeans. Seeing the huge light ball as hot as the scorching sun, I cheered excitedly, rushed up, swallowed it up, and soon became strong.

The light ball as big as the scorching sun is a very pure spiritual body, without any consciousness, and is allowed to be swallowed by the spirit of the Pure Yang Mind Sword. The ratio of the two quickly reversed.

When the Chunyang Spirit Sword Spirit swallowed the huge ball of light, it burst out with spiritual fluctuations like a tide, constantly emitting attachment to Ye Chen.

"I've finally been promoted to a top-quality spiritual weapon!"

Ye Chen was overjoyed and thoughts changed. The Chunyang Spiritual Sword flew out from the Yuanhai of Dantian and floated in front of him.

At this time, the Pure Yang Spiritual Sword had undergone a tremendous change, three feet long, and the sword body was as transparent as the source fire. It was silent when it took action and was difficult to detect it.

"Send me some of the energy of the immortal world!"

Zhizhi had already made preparations, and when the Chunyang Spiritual Sword emerged, it was immediately portrayed in the void.

Her fingertips emitted a little green light, like a flash of lightning, drawing in an instant, and a mysterious rune restriction slowly took shape.

Ye Chen did not say anything, and directly used the source fire to refine a stream of immortal world energy, held Zhizhi's Rouyi, and passed the energy to her.

He had a treasure that could refine the vitality of the immortal world. Zhizhi obviously discovered this, but both of them pretended not to know it and did not reveal it.

With the support of the immortal world's energy, the rune prohibition in the void instantly shone brightly and became brighter, and was shot into the Chunyang Spiritual Sword by Zhizhi.

At this moment, the lightning flashed on the Chunyang Spiritual Sword, and the space was instantly filled with thunder.

The inner space of the Pure Yang Immortal Furnace seems to have become a lightning world, with thunder everywhere, colorful, and powerful terrifying fluctuations.

"The restriction I entered into the Chunyang Spiritual Sword is the thunder ban. From then on, this flying sword has the power of thunder."

Zhizhi portrayed the ban, which seemed to consume a lot, and she breathed for a moment before saying.

The lowest-grade ban has been completed!
Chapter completed!
