Zhang Heng had five spiritual weapons at this moment, including Wu Ling Jian and Yue Shang, two spiritual weapons, which he did not intend to take them out and refine them first.

In some aspects, Yue Shang's value is no less than that of ordinary top-grade spiritual weapons, and its power is much stronger than that of ordinary middle-grade spiritual weapons. Zhang Heng regards this spiritual weapon as his secret weapon, and even if Fang Yun gathers next month, he will not be easily used.

Compared to Yue Shang, who is a secret weapon, the Wuling Sword is a spiritual weapon that Zhang Heng usually uses, and it is good to cover up the eyes and ears.

The unknown auxiliary spiritual weapon obtained from Ning Xuerong is not refined for the time being, because he vaguely felt the unusualness of this hairpin, and he didn't want to refine everything Ning Xuerong had in his heart.

The remaining two medium-grade spiritual weapons are the broken Fire Feather Fan and the Lingshuang Jade Pendant. Such damaged medium-grade spiritual weapons must be re-refined by cultivators in the Foundation Establishment Stage. Even if they are re-refined, their power may be reduced a little.

However, for Zhang Heng, it is not important whether this spiritual weapon is broken or not. He does not need to use these two spiritual weapons, but to "refinish and absorb" the essence of the spiritual weapon contained in it.

First, I picked up half of the Lingshuang jade pendant, then put the other spiritual fragments and the Mother of Tieling aside, and then began to close my eyes and concentrate. The visceral aura in my body drilled out of my body like a spiritual snake, and rushed straight to the half of the Lingshuang jade pendant in my hand.

A faint silver light flowed on Zhang Heng's body, and the visceral spiritual energy in his body flowed out of his dantian, then reached the Lingshuang jade pendant outside his body, and after rotating on the surface of half of the jade pendant for a while, it finally flowed back into his body.

The two major cycles inside and outside the body flow continuously, forming a clever balance. Zhang Heng could feel that the essence of the Lingshuang jade pendant was entering his body with the cycle of refining the virtual spiritual energy.

However, the refining speed this time seemed to be much slower than the previous one. After one full hour of refining, a few inconspicuous cracks appeared on the surface of the spiritual weapon.

When a large crack appeared on the jade pendant, Zhang Heng found that his refining speed had increased a lot. He felt that the essence of the spiritual weapon flowed through his body a lot of speed, and the operation of the refining spiritual energy was even more round and smooth.

About another hour, the jade pendant in Zhang Heng's hand turned into a pile of gray powder and sprinkled on the ground. The essence of the spiritual weapon had been completely refined and absorbed by Zhang Heng.

After feeling it slightly, Zhang Heng found that the effect of refining half of the Lingshuang jade pendant was equivalent to the effect of refining two low-grade spiritual weapons. His guess was correct. Spiritual weapons with high grades must have a greater effect than ordinary spiritual weapons.

He reached out and picked up his other half of the Lingshuang jade pendant. Zhang Heng used the Void Refining Spiritual Qi to absorb the essence of the spiritual weapon. This time the speed was much faster than the last time. In total, he completely absorbed the essence of the spiritual weapon in just over an hour.

It seems that as the number of refining increases, the faster the refining speed, and the more time it takes to refine spiritual weapons with higher grades.

When Zhang Heng was about to continue refining the remaining spiritual weapon Fire Feather Fan, his hand that stretched out suddenly stopped.

In a vaguely, he felt that the spiritual energy of refining in his body was not as smooth and natural as before, and his body seemed to be unable to withstand the flow of spiritual energy in his body at this moment.

It seemed that he was a little anxious to achieve success. Zhang Heng temporarily gave up his plan to continue refining, closed his eyes and meditated, circulating the vital spiritual energy in his body.

The silver-white light flowed through his body, constantly enhancing his health, including his skin, organs, muscles, and bones...

With the help of the mysterious jade tube in his mind, his spiritual sense easily merged with the spiritual energy of refining the Void. While the spiritual energy of refining the Void is transforming, it is also constantly enhancing his spiritual consciousness.

I don’t know how long it took, but it felt that it would take much longer than it would take to refine the essence of the spiritual weapon. Zhang Heng was finally able to control the Void Refining Spirit Qi in his body, and was able to withstand the operation of Void Refining Spirit Qi in his body.

Zhang Heng opened his eyes and picked up another medium-grade spiritual weapon Fire Feather Fan. Although the fire Feather Fan was also broken, it was a complete spiritual weapon and was not divided into two pieces. Zhang Heng decided to refine it at one time.

The refining speed this time increased a lot. When the entire fire feather fan turned into a pile of coke-like powder, it only took less than two hours.

Afterwards, Zhang Heng meditated and began to condense his own ** and strengthen the strength of his spiritual consciousness.

It felt that the speed of condensation was not increasing very quickly. After another period of time, Zhang Heng woke up from the state of entering into meditation, and the light in his eyes flashed by.

Looking at the piles of powder underground, Zhang Heng sighed inwardly that four spiritual weapons had been refined into slag by himself, two of which were medium-grade spiritual weapons, and the other two were low-grade spiritual weapons. A medium-grade spiritual weapon could be comparable to four low-grade spiritual weapons. In total, Zhang Heng had refined ten spiritual weapons.

Ten spiritual weapons are not enough to bring him to the first level of the first level. According to the instructions in the mysterious jade tube, at least a dozen spiritual weapons must be needed to achieve his goal.

Zhang Heng's eyes fell on the dark Tieling Mine Mother, with a look of hope in his eyes. With the grade of Tieling Mine Mother, it should be enough to let him step into a first-class realm.

Taking a deep breath, Zhang Heng picked up the Tieling Mine Mother. At this moment, he felt that the ore in his hand seemed to be heavier than before.

His eyes were staring at the Tieling Ore Mother in his hand. Zhang Heng did not close his eyes this time because he was already familiar with the method of refining the essence of spiritual weapons and could no longer be familiar with it. He no longer needed to refine the Tieling Ore Mother by entering into meditation.

In addition, he also wanted to observe the specific process of refining with his own eyes.

A faint silver light extended out of his body and soon flowed to the dark and thick Tieling ore mother. After circulating on the ore surface for a week, it flowed back into the body again.

Time passed little by little, and Zhang Heng discovered that there was no change on the surface of Tieling ore mother.

One hour, two hours, three hours...

If it weren't for Zhang Heng who could feel that the essence of the Tieling Ore Mother had indeed flowed into his body, then he would really doubt whether this Tieling Ore Mother could work.

As time passed, Zhang Heng stopped a few times in the middle to temper his own health and improve the strength of his spiritual consciousness, and he also spent a lot of time during this period.

So in this way, the essence is extracted, the ** and spiritual consciousness are condensed, and the essence is extracted again...

Day turns into night, night is replaced by day, and several days and nights have passed.

Finally, at some point, when Zhang Heng was bored himself, he found that several slight cracks appeared on the surface of the Tieling Mine Mother.

Although this means that the refining progress has made great progress, Zhang Heng was happy and could not help but worry. I wonder if this Tieling Mine Master can achieve his expected goals?

In this way, the cracks on the surface of the Tieling ore gradually became larger in Zhang Heng's eyes. Although the cracks expanded very slowly, Zhang Heng was still a little worried.

After a long time, the cracks on the surface of the Tieling Ore mother became half a centimeter wide, and the abnormal skills Zhang Heng practiced reached a limit, and the increase of ** and spiritual power became much slower.

"Click"

At some point, the Tieling Mine Mother suddenly split into four or five pieces, and a silver-white light burst out from Zhang Heng's body at the same time.

Suddenly, the entire practice room trembled slightly, and even the several defense restrictions set outside swayed a few times.

Then, the silver-white light outside Zhang Heng's body began to retract, dimming little by little, and diminishing little by little, like a stream flowing into the ocean, and finally all entered the depths of his dantian.

At this moment, deep in Zhang Heng's dantian, a silver light ball as big as a pea was trembling slightly, and a suffocating breath emanated from the silver-white light ball.

Zhang Heng concentrated for a long time before the pea-sized silver-white light ball stopped, the spiritual energy in his body also returned to calm, and the suffocating and terrifying aura on his body disappeared. At this moment, he was no longer different from the ordinary Qi Refining Cultivator.

Looking at the Tieling Mine Mother on the ground, Zhang Heng's face was filled with ecstasy expressions. Unexpectedly, the Tieling Mine Mother's role was even greater than he expected. Even if he did not completely refine it, he officially entered the level of abnormal skills.

At this moment, Zhang Heng's strength has reached a new level. With every move, he could feel the strong power contained in his body, and he also felt that there was a huge potential treasure hidden in his body.

Zhang Heng wanted to test his true strength at this moment, but he didn't dare to make big moves, so he gently spit out a mouthful of silver-white aura.

With a "magnetic" sound, the silver-white spiritual energy rushed into the layers of restriction opposite like a stream of water. Explosions burst out from the air, and a harsh explosion sounded inside the house.

The seven or eight defensive restrictions that Zhang Heng had previously exhausted his mana were broken in half in the blink of an eye.

Seeing this scene, Zhang Heng couldn't help but take a breath of air. The power of this refining spiritual energy was beyond his imagination. With so many defensive restrictions, even the monks in the Foundation Establishment stage could not easily break half of the restrictions without using their spiritual weapons.

Of course, this does not mean that Zhang Heng's refining spiritual energy at this moment is stronger than that in the body of the monks in the foundation-building stage.

Zhang Heng couldn't help but remember a sentence in the first floor of the ancient tower about the refining spiritual energy:

Refining the spiritual energy of the emptiness, reaching the sky and the earth, and being at the same level as the same level, I am the king!

I am the king!

What a powerful and arrogant this is!
