Yun Fei approached the body of the big spirit monkey. It was obvious that Yun Fei seemed to be looking for something. "Sure enough," Yun Fei said intimately that he found something in the part where the big spirit monkey was leaning into his heart.

This is a diamond-shaped crystal. It looks a little impurities on the outside, and it looks like a contaminated crystal, but Yun Fei knows that this is the core of the monster, the magic crystal.

Magic crystals have a great effect. Whether it is advanced forging, spell research or even cultivation, they need to use magic crystals as a certain carrier to complete.

If the impurities of the magic crystal are smaller, the higher the bloodline purity of the monster. Of course, high-purity monsters are very rare. It is said that when your Azure Dragon Beast is a descendant of the ancient dragon god, your bloodline purity is extremely high, and you can naturally reach level 5 or above.

Immediately, Yun Fei continued to search for the little spirit monkey and found the magic crystal, but it was a little smaller than that, but Yun Fei didn't care at all. Even if it was sold, it would be equivalent to the income of a normal family for half a month.

As soon as he returned home, Yun Fei, who was slightly tired, immediately began to meditate. After an hour, Yun Fei quietly woke up and his energy and spiritual power had returned to his state before departure.

Yun Fei held the first-level magic crystal, and all the spiritual energy on his body was mobilized to the magic crystal. The magic crystal seemed to have been summoned by some kind of summons. After a while, the magic crystal instantly became dim and dull.

Yun Fei instantly felt that his spiritual power was much more exquisite, but it seemed that he was still quite far from the next level.

"According to this kind of improvement, even if I absorb the second-level magic crystal, I will not be able to reach the middle stage of the Spiritual One." Yun Fei murmured to himself.

"Tempering the crystal" suddenly thought flashed, and Yun Fei immediately searched through the bookshelf left by his mother and found it.

The so-called tempering of crystals is to use special methods to forcibly filter impurities in the magic crystals and directly absorb the essence of the magic crystals. This is almost universally known among spiritual masters, but Yun Fei didn't understand it as soon as he stepped in.

"According to the meaning of the book, I just absorbed only one-third of the spiritual energy I obtained." Yun Fei felt a little mute and ate Coptis chinensis in an instant.

Immediately afterwards, Yun Fei saw that according to the method in the book, the spiritual master below the spirit body must use second-grade or above forging fire to absorb. Fortunately, Yun Fei awakened that the fire attributes did not need to be considered. Put the magic crystal into the furnace for tempering.

A fire appeared in Yun Fei's hand, which was obviously improved by the little spirit monkey magic crystal and became more and more capable of controlling spiritual power. It was much stronger than the shaking little flame.

Half an hour later, Yun Fei finally saw the impurities separated from the spiritual power of the magic crystal. Yun Fei immediately stopped providing spiritual power, and the flame disappeared. Yun Fei looked at the magic crystal carefully. What was strange was that the crystal was tempered with flames. The temperature of the crystal itself still did not change much. Fortunately, the separated impurities and more essence spiritual power were telling Yun Fei that he had succeeded.

With a cup of tea, Yun Fei easily absorbed the magic crystal. In addition to encountering some obstacles in the initial transformation, the spiritual power successfully absorbed his hands. Now Yun Fei has reached the peak of the early stage of the Spiritual Master.

"It's still a little bit too long. If you absorb a second-level magic crystal or several first-level magic crystals, you might be able to break through," Yun Fei said intimately.

Yunfei set out towards the Qingshan Mountains for several days. Even if Rus looked for Yunfei, Yunfei refused to make a breakthrough. Rus was helpless. Rus also understood that the stronger the spiritual power, the better, otherwise it would not be forged for a long time.

One night a few days later, as two first-level magic crystal spiritual power was sucked into Yun Fei's body, the next moment, the magic crystal became dim and dull.

Spiritual power is a very mysterious thing. People don’t know when it appeared. When it was recorded in the human race, spiritual power had already existed. It gave people a pleasant experience that they would not get in daily life. At the same time, the existence of spiritual power also allowed the originally weak human race to resist the invasion of foreign races.

Yun Fei could clearly feel the dantian in his body, which was moving and cheerful. Whenever a trace of spiritual power penetrated into the dantian, it became more pure and essence in a blink of an eye, as if everything began to sublimate.

"Wonderful" Yun Fei sighed in his heart. With the blessing of the Dantian, the originally quiet spiritual veins began to rush towards his body. Each increase in spiritual power is to expand the original reserves, and at the same time, it also raises the realm of spiritual power to another level. This is the beauty of spiritual power.
