Over a black mountain range, an old Taoist with a Taoist boy slowly landed on the top of the mountain. A middle-aged monk had long stood on the top of the mountain. At the moment, seeing the old Taoist descending, he smiled and said, "brother Zhong, what a coincidence."

"Brother Yanan, you are here too. What's the matter?"

"In my dream, I suddenly dreamed that there were strange things calling here. I heard someone mention that a secret place appeared. I'm here to have a look."

"Oh?" the Taoist's face tightened. "I had a similar dream. Is it true that there is a treasure to choose the Lord?"

"You and I have been good friends for many years. We might as well go and have a look together."

"That's good."

Then, their bodies slowly flew up and began to check the mountains everywhere.

Not far away, a young monk looked at them strangely. "Didn't Shifu say that no one found it here? How could someone be looking for the secret place? It's hard to explain to benefactor Yue."

In the small cave, Song Fei stared at the materials in front of him.

"Try again for a while. If you really can't, go and buy something related to the alchemist and return to Qingtian sword school as soon as possible."

The melting process of the material is very smooth. It has been completed in two hours. Next, it is necessary to integrate with each other. Song Fei sank into his mind, integrated the perception of the golden way into the melted material, and then carefully controlled the flame and played out one after another.

In the furnace, the flame is tumbling and changing, and drops of liquid slowly begin to converge and condense under the trend of flame.

Song Fei paid close attention to the whole God. In the past month, he has experienced too many failures in this process. He knows that one is bad and another is the end of failure.

Mutually exclusive liquids need to be perfectly fused by using the device refining method. For liquids that are easy to fuse, they need to be temporarily separated to prevent too fast fusion. In this fusion process, not all liquids are directly doped together, but they are fused step by step in order and according to the method of the mixer.

After only more than ten minutes, Song Fei was sweating. Integrating this step is really too laborious. Coupled with the melting in front, Song Fei's spiritual power has been nearly half.

A pill to restore mental power was redeemed and swallowed, and immediately restored the spirit of dragon and tiger. In order to better control, we can't only rely on willpower, we can only consume the pill.

The flame makes a loud noise in the furnace and shows various shapes in the furnace like dancing. The flying flame forms various rules and has a soul stirring beauty.

At this time, Song Fei narrowed his eyes slightly, relying on the perception of the golden way to replace his eyes, and turned a blind eye to the beautiful scenery in front of him.

Every drop of liquid, driven by the flame, approaches and merges with each other. The fusion of each drop of liquid consumes a lot of Song Fei's spiritual strength,

Two hours later, fortunately, the integration went smoothly after two-thirds. Song Fei also mentioned his heart. At this time, if one is not good, all the previous efforts will be wasted.

The Dharma formulas continued to be played out by Song Fei in an orderly manner. The burning flame turned Song Fei's face red, making every pore of Song Fei clearly visible in the dark cave. At the moment, Song Fei's face was covered with sweat, just like the whole person was drenched in the rain.

"OK." I don't know how long later, the magic bead on Song Fei's shoulder suddenly drank faintly. With the sound of the magic pearl falling, Song Fei also showed a satisfied smile on his face. After a month of hard work, he finally succeeded in the integration of materials.

The next step is relatively simple -- refining the essence and removing impurities.

At this moment, the magic pearl said: "many refiners' refining techniques are in
