The black dark fire, quickly wrapped around Fang Yi's hand, fell directly towards the rat king who was still struggling in mid-air.

His body trembled, and the Rat King felt the fear that penetrated deep into his soul. In the moment when the dark fire appeared, even if it cultivated well, it was still terrified like an ordinary mortal beast. I completely forgot that I was a demon beast and could use my spiritual power to cast spells.

"Zizi".

The dark fire fell on the rat king, and it made a burning sound all at once. And in this sound, the Rat King was as weak as a mortal mouse, and he could only keep writhing his body in the air and struggling.

Under Fang Yi's control, the Rat King was in his body. The spirit essence liquid that was incinerated by the dark fire did not flow into his body. Rather, bit by bit, it was gathered in Fang Yi's hands.

A sense of weakness surged up like a tide, under the action of the dark fire in Fang Yi's hands. The Rat King only struggled for more than ten breaths, and then slowly stopped struggling, completely out of breath.

Draw your sword and catch the fallen crystal. At the same time, Fang Yi took out a jade bottle and carefully collected the spirit essence liquid into the jade bottle.

Put away the spirit sword and looked at the spirit yuan liquid, demon crystal, and fire crystal in his hand. Fang Yi's heart was very satisfied.

It's not in vain that he has put so much effort into it, and these things are finally in hand. Now, with this thing, needless to say, his cultivation and physique will definitely reach a new height.

There was no other movement to take a look at these things. Fang Yi poured the spirit essence liquid into his mouth, and at the same time, he took the demon crystal into it.

Although theoretically speaking, it is enough to use only the spirit essence liquid. It was enough for him to impact the fifth layer of Qi refining.

But who let him have such a thing as a dark fire! And he himself attaches more importance to his own base. After this spirit essence liquid was burned by the dark fire, it was already a pure thing. It can be used to advance, but it is not enough, and it may be burned and enriched.

As for adding demon crystals. Although he originally planned to use the demon crystal as the fire source for refining his body. But now there's a fire crystal. This is more suitable for something that is a source of fire. He still left the demon crystal and used it to improve his cultivation.

The Yuan Spirit Liquid was like a small stream, pouring into the veins of his whole body through Fang Yi's mouth. In the space of dozens of breaths, Fang Yi ran the Qi Refining Technique, and after several large and small weeks.

These Yuan Spirit Liquids flowed towards his dantian little by little.

"Zizi".

The turbid gas is emitted from Fang Yi's body surface. The spirit essence liquid in his body was condensed little by little again when it passed through the dark fire at this moment.

I feel that the spirit essence liquid may still be a little insufficient. Fang Yi gritted his teeth and directly bit the demon crystal in his mouth to pieces.

The rich, much purer aura than the spirit essence liquid, slowly spread out among the square dentures.

The demon crystal of the foundation realm is really extraordinary. The aura contained in it is indeed not comparable to ordinary spiritual objects.

After swallowing these spiritual qis, Fang Yi once again activated the Qi Refining Technique. As he thought, under the impact of this thick aura, the meridians in his body were slightly swollen.

didn't care too much about this, with the experience of the previous times, Fang Yi can be said to be familiar with it.

This was something that made his meridians swell, like spiritual liquid. It didn't take long for everything to flow into Fang Yi's dantian, where the dark fire was.

"Zizi".

Like the spirit essence liquid, this rich gas was also incinerated as well. It was almost a few breaths of effort, and the turbid gas that had stopped emitting from the surface of the body had stopped. Began to emanate again.

Compared to the previous Lingyuan liquid, this is a rich gas. There was obviously not so much residue that had been burned. What was left in his body was much more than before.

Sensing this, Fang Yi was stunned. However, then I figured it all out.

Demon crystal, compared to the spirit liquid smelted by the Rat King. In terms of energy level, it is obviously a lot higher.

The energy level is higher, and the waste residue contained in it will be significantly reduced. Therefore, there are no longer so many things that are scanned by dark fire.

Thinking of this, Fang Yi thought slightly. He decided to use a high-level energy source to cultivate as much as possible in the future, so that it would be more beneficial to his foundation. It is also of great benefit to his cultivation advancement.

However, high-grade energy sources are so easy to get. Not to mention that at the normal market price, it cannot be exchanged at all. Let's just say that according to its own scarcity. There is also very little circulation in the market.

Sighing, facing this question, Fang Yi felt distressed in his heart.

The aura is faint, slowly. His cultivation began to move towards the fifth level of Qi refining, and sensing this, Fang Yi put away his cranky thoughts.

More on that later. As for now, he still takes care of everything in front of him first.

The aura occupies the space of the dantian and begins to expand with difficulty. Under the replenishment of the aura after the dark fire burned, finally, Fang Yi faintly felt the diaphragm from the fourth layer of Qi refining to the fifth layer of Qi refining.

Hit with all your might. The leap between realms is not so simple when the aura is enough.

Although, compared to the leap of the great realm. and the leap of two pairs in the realm of qi refining. The difficulty of reaching the fifth layer of Qi refining from the fourth layer of Qi refining is much easier.

But a person like him with an extremely poor spiritual root still has to work hard to impact this realm.

Once, twice, three times ..........

"Bang".

There was a soft sound in his body, after nine full efforts. Finally, in a faint and imperceptible sound. Fang Yi successfully crossed the fourth layer of qi refining and became a fifth-level cultivator of qi refining.

Slowly opened his eyes and felt it. Now the power contained in his body, Fang Yi nodded with satisfaction.

didn't disappoint him, the power of the fifth layer of Qi refining, after he perceived and understood. It can be said that with his current strength, it is absolutely no problem to calmly escape from the twin brother who holds the token.

Even, now he is doing his best. The ordinary seventh layer of Qi refining in World War I was no problem. Of course, this is a treasure that is built on the seventh layer of Qi refining that is ordinary enough, and there is absolutely no treasure in his hand, like the Rat King, which he got from the powerhouse of the Foundation Building Realm.

Looking at the fire crystal in his hand, Fang Yi's eyes froze. He took out another bottle, which looked very thick, and the golden body liquid extracted from the medium-grade spirit weapon.

After a little thought, Fang Yi decided to forge his physique here. Although the physique is forged here, in the end, it is indispensable to remove the jade pendant protection and face the extraordinary temperature here.

But this risk also has the benefit of taking risks. After success, according to his expectations, his physique will be several times stronger than that forged outside.

Of course, the consequences of failure can also be miserable. In this case, although it will not lead to death, it is indispensable to recuperate in bed for a month or two.

When you pat the storage bag, there is a flash of light on the storage bag. A three-legged round tripod was taken out by him in this way.

Seeing this, Fang Yi nodded with satisfaction. This Ding is not bad, the materials used to refine it are all about the same level as medium-grade spiritual weapons.

However, for some reason. In the end, it still failed to forge a medium-grade spiritual weapon, and only achieved such a simple low-grade spiritual weapon.

But Rao is so, in order to get this tripod. He also paid a lot of price before.......
