Chapter 12 Observation and Learning

After some exploration, Chen Daoren and others did not find any results.

This underground fire seemed to appear out of thin air, and no one could find its source.

The family monks explored here to no avail, and when they were impressed by the wonders of nature, they simply used this underground fire to build an underground fire room for refining.

Entering the underground fire room, Chen Qingyun was full of interest.

Chen Qingyan introduced the facilities here, how to control the formation, and control the temperature and temperature of the underground fire.

At the same time, he explained the usage of some refining materials around.

In this way, after a brief introduction, Chen Qingyan began to refine the red iron sword.

In the next few days.

Chen Qingyun watched the whole process.

From time to time, he would try to melt some materials, try to adjust the temperature of the underground fire through the formation, and constantly accumulate experience.

...

The whole process of observation and learning lasted for ten days.

Chen Qingyun benefited a lot, and was eager to start refining by himself.

Chen Qingyan refined 16 red iron swords, with a yield rate of about 70%.

Chen Qingyun didn't know what the yield rate would be.

With Chen Qingyan's guidance, he could just try boldly and refine it.

Chen Qingyun was already familiar with this earth fire room.

He also had a clear understanding of the control of the formation.

"Qingyun, you try it next."

At Chen Qingyan's invitation, Chen Qingyan took a deep breath and began to refine the red iron sword himself.

He took out three pieces of red iron and placed them aside.

He injected mana into the formation, controlled the earth fire to a suitable temperature, and released a raging fire. Chen Qingyun looked serious.

Before, he watched Chen Qingyan refine the weapon without doing it himself.

Now, he was refining it himself, and Chen Qingyun felt a little nervous.

Chen Qingyan was silent on the side, paying attention to Chen Qingyun's actions.

Chen Qingyun had watched the refining of the red iron sword many times and was familiar with all the processes.

Without her speaking, Chen Qingyun knew how to refine it.

However, whether a red iron sword could be refined in one go depended on Chen Qingyun's comprehension ability.

When the earth fire reached a smelting temperature.

Chen Qingyun used his magic power, holding a piece of red iron, flew into the earth fire, and began the first step of smelting.

This step seemed simple, but it required controlling the temperature of the flame to achieve a smelting temperature, and the red iron could not be over-melted.

Otherwise, it would damage the power in the red iron.

The red iron was burned by the earth fire, and the color gradually turned deep red.

It took more than an hour for the red iron to finally melt and be smelted into a ball of liquid metal.

In addition.

It is also necessary to smelt the hundred-refined steel and fuse it with the red iron metal liquid to play a consolidating role.

The red iron sword made in this way will also become harder and more wear-resistant, and can improve toughness.

Strictly speaking, hundred-refined steel is not a first-level refining material, and cultivators can buy it with real gold and silver.

Real gold and silver are easy to obtain for cultivators, and are not valuable.

This underground fire room stores a large amount of hundred-refined steel.

Chen Qingyun used his magic power to lift a piece of hundred-refined steel from the shelf and put it into the flame.

Compared with red iron, hundred-refined steel is easy to melt and belongs to ordinary iron.

It only took about a cup of tea for the hundred-refined steel to be melted into liquid metal.

The first step of smelting is completed.

The second step is fusion.

Fuse the two liquid metals together.

This step is not very difficult.

Chen Qingyun observed and learned many times, and soon completed the fusion process.

So that the third step is shaping, shaping the liquid metal into the shape of a flying sword.

This step, Chen Qingyun just spent some more time to shape it.

A flying sword appeared, three feet long, red all over, and still in a high temperature state.

After completing three steps in a row, only the last step of engraving the formation remained, and Chen Qingyun's expression became more solemn.

This is the most difficult and most critical step.

Only when the formation is engraved in the flying sword can the effect of storing power and controlling it be achieved.

This is the difference between ordinary weapons and magic weapons.

A weapon without an inscription formation, no matter how hard it is or what material it is made of.

But without an inscription formation, it does not have spiritual power and cannot be controlled by cultivators. It can only be regarded as an ordinary weapon.

Only weapons with inscription formations can be called magic weapons.

The red iron sword has two layers of formation patterns.

When observing Chen Qingyan refining the weapon, Chen Qingyan once emphasized that this step must be very careful and not be sloppy.

Once there is an error in the inscription formation, it will not be possible to erase the formation pattern and perform the second inscription formation.

The refining will also be declared a failure.

Chen Qingyun took a deep breath, constantly recalling the steps of Chen Qingyan's engraving array, engraving the array pattern bit by bit.

Chen Qingyan, who was standing by, did not speak when seeing this, but watched quietly, not daring to disturb Chen Qingyun.

As time passed, when engraving the second layer of array pattern, Chen Qingyun's engraving technique still had problems.

There was an error in the engraving of the array pattern, and the divine thought was not in place, which made the unformed array pattern dim and lost its charm.

"It's a pity, I was too eager to succeed, and the divine thought control was still not accurate enough."

Seeing the array pattern lose its luster, Chen Qingyun smiled bitterly and felt it was a pity.

"When you engraved the second array pattern to the fourth step, you still didn't control your mind. Next time you reach this step, you might as well slow down a little and don't be too impatient."

Chen Qingyan's voice sounded, very gentle, telling where the mistake was.

"Qingyun, this is the first time you refine it, you can do this step of engraving the array, and you are almost successful. You have done very well."

"I was far inferior to you when I refined it for the first time."

She comforted him.

"No matter how powerful the refiner is, he can't guarantee that every refining will be successful. You should summarize your experience this time and do it well next time."

"Adjust your mentality and do the second refining."

Chen Qingyun smiled when he heard it, and he was not discouraged.

Putting the abandoned broken sword aside, Chen Qingyun calmed down and started the second refining.

Although there are still two pieces of red iron, he doesn't want to fail again.

From smelting, to fusion, to shaping, the first three steps were still passed smoothly.

Once again reached the stage of inscription, this time, Chen Qingyun's movements were more skillful and his techniques were more stable.

Time passed bit by bit.

From the first array pattern taking shape to the second array pattern being successfully inscribed, Chen Qingyun was completely immersed in the whole process.

He finally successfully inscribed the two layers of array patterns on the red iron sword.

The two layers of array patterns flashed with light and hid in the sword embryo, activating this magic weapon.

A flying sword was suspended in the flames, emitting a hazy glow and became the focus.

"Is the refining successful?"

Chen Qingyun's eyes condensed, and his sight fell firmly on the flying sword.
