Wait until the red flame iron is completely melted into a 'lava' state under the scorching fire. With another move with his right hand, Chen Yuqi took out another refining material from the Qiankun bag and invested it into the furnace ding.

This new refining material is the material that is particularly light in weight, its name is Qingyu Rock, its color is dark blue, and it is also a high-grade refining material. Chen Yuqi deliberately picked the smallest and lightest color piece from the pile of Qingyu Flames for hand practice.

However, what Chen Yuqi didn't know was that this piece of Qingyu Rock with the lightest color was not an ordinary Qingyu Rock, it was the core of the entire Qingyu Rock vein - Qingyu Chalcedony!

Green feather chalcedony is very rare, and only a piece as large as a fingernail can be found in thousands of green feather rock veins. And what Chen Yuqi threw into the furnace just now was the size of a duck's egg!

If Chen Yuchen learned that the stone she threw into it just now was such a valuable item, it is estimated that she would have the urge to chop her hands!

The two materials were burned in two separate fires, and Chen Yuqi's forehead was slightly sweaty, and she was already a little struggling to use it for three purposes.

With the passage of time, the newly added green feather chalcedony seems to have been successfully calcined, and gradually turned into a 'pale cyan fluid' recorded in the classics.

However, this criterion is the success of forging for Aoyu Rock. In fact, the green feather chalcedony could not be successfully trained by the fire alone, and it was necessary to add other violent flames on the way to the forging from the fire! However, it was almost impossible to do so.

In addition to the green feather chalcedony, the color of the red flame iron also became darker, and the crimson flames gradually decreased, but the color also changed to crimson.

At this time, more than half of the mana in Chen Yuqi's body had been consumed. In the sea of dantian qi, the liquid vortex has also become a little thin.

Gritting his teeth, Chen Yuchen took out a fine refining material burst vine from the Qiankun bag again and threw it into the furnace.

In an instant, the flames in the furnace flashed, and it meant to be extinguished.

Chen Yuqi calmed down, the mana output was stable again, and the three flames in the furnace slowly stabilized and continued to burn slowly.

Operate the mana into the furnace and mobilize the formation to run. The spiritual power was divided into three strands, each manipulating the three flames to calcine the materials inside to varying degrees.

"Poof!"

Suddenly, the flames in the furnace suddenly burst out, and the refining materials that had been put in at the end turned into charcoal by themselves under the flames of the sudden riot.

Chen Yuchen was startled, but she was only stunned for a moment, and then she controlled the spiritual power in her mind, spurting out like a spring, and entering the Ding Furnace to stabilize the other two calcined material flames.

After everything stabilized, Chen Yuqi felt a tingling pain in his head, which was a manifestation of too fast consumption of mental power. In this way, the mana and spiritual power were groggily operating to calcinate the two remaining materials in the furnace, and time passed inadvertently.

Just when Chen Yuchen wanted to insist on a period of time before adding the third material to forging, the spiritual power in his mind involuntarily rushed towards the furnace ding!

The spiritual power was sucked into the furnace like a flood that opened the floodgates, and it was instantly depleted before Chen Yuchen could react. Then she felt as if someone had smashed a brick and fainted gorgeously!

Time rewinded, and the fire in the furnace was inexplicably restless, destroying a calcining burst vine. At the same time, the other two materials were inexplicably close together at that moment.

Generally speaking, if you don't use a special fusion technique, the two different moments when you get close to the fire will clash with each other, and then the materials in both will turn into slag!

However, the proximity of these two flowers to each other is in a very special situation: the fire is rioting, and the heart is entangled.

In the same way, the two leaves of the fire blended together, and the two materials calcined inside were slowly approaching.

At that time, Chen Yuqi was still in a trance with a stinging mind, and he only subconsciously used his spiritual power to stabilize the flames, but he did not separate the two from the fire. Subsequently, the two materials are quietly calcined next to each other. In the end, the red fire iron solution gradually turned into a small furnace, enveloping another ball of green feather chalcedony fluid.

The red fire iron was calcined from the fire, and the red fire of the red fire iron melted the green feather chalcedony. When calcination reaches a certain level, green feather chalcedony requires a lot of mental power to shape it. That's it, the only remaining spiritual power in Chen Yuqi's mind was directly drained, and he fainted directly before he could react.

After Chen Yuqi passed out in a coma, her left hand was still sucked on the furnace ding, and the mana in her body surged towards the furnace ding at a steady speed. Because of this, her body still maintains a cross-legged posture, but her head is lowered, as if she is asleep.

Inside the furnace, a white flame burned quietly. Within the white flames, a small furnace made of crimson 'lava' swirled. Inside the Crimson Furnace, the blazing red fire was scorching the pale cyan fluid in the middle.

The clump of blue fluid in the center is constantly changing shape, or sword, or knife, or bell, or umbrella. With the calcination of the red fire, its color became lighter and lighter, gradually changing from light green to green and white, and finally from green and white to pure white.

Finally, when the mana in Chen Yuqi's body was about to be exhausted, the situation in the furnace had undergone a new change.

Under the continuous scorching of the fire, the red fire iron slowly turned from a 'lava' state into a red flame, and gradually decreased, and the furnace composed of flames gradually became thin, and it seemed that it could dissipate at any time!

At this time, the original blue-white fluid in the innermost part had turned into a small sword as pure white as jade, slowly trembling in the center of the Red Fire Furnace, as if it was completely forcing out the remaining magazines in the body!

After a moment, the red fire disappeared, and it seemed to be completely absorbed by the white jade sword in the very center.

Then the fire also disappeared at this time, and the furnace Ding no longer extracted the mana in Chen Yuqi's body. In the end, only the white jade sword was left suspended alone in the center of the furnace, waiting for the master's collection!

..............

I don't know how long time has passed, but when Chen Yuchen woke up, he found himself cross-legged, his head on the stove, and he fell asleep like this.

Holding his forehead, which was still a little dazed, Chen Yuqi quietly thought about why he was sleeping here.

"I'm doing refining exercises, and I'm going to make a fairy sword for myself after I'm done!"

"I'm tempering the Red Fire Iron, Green Feather Rock, and Burst Vine, and then the furnace Ding is out of flames and riots, and the Burst Vine is scrapped......"

Although he was mentally prepared, he couldn't help but feel distressed when he thought that this precious material had been directly refined and scrapped by himself.

"Then, I will calcine the Red Fire Iron and Blue Feather Rock steadily for a while........ I'm going to faint?!"

Thinking of this, Chen Yuqi looked at the furnace Ding cautiously.

"Huh!?"

Just when she thought she would see a pile of ashes, she found a small white jade sword suspended in the furnace!
