"Teacher, I'm going to Zhaoyao Mountain, the Treasure Book of Mountains and Seas should have been born. ”

"I've also noticed this, it doesn't matter if you're born or not, you can't find it alone if you're born. In previous years, some forces converged together, and according to the ancient records of their respective clans, they deduced the general location of the treasure book, just like looking for ginseng. Now those big forces don't know why most of them are Hui, only some of the little minions are left, and you won't be able to touch anything if you go. For thousands of years, how many people have gone to look for it, and they can't even touch the shadow of the treasure book. So don't worry, once those big forces make any moves, I'll let you go to Zhaoyao Mountain. Chihong gave Long Yuan a reassuring look.

"Okay. My cultivation is still low now, so I just took advantage of this time to step up my cultivation. ”

"I've been thinking about how I can make you quickly improve your refiner's attainment, think about it or cramm, get ready, it's not so easy to learn refiner. When the real gas cylinder is refined, come to me. Chihong pointed his finger to the center of Long Yuan's eyebrows, and left time for him again.

Long Yuan sat cross-legged and contemplated, while inducing the true qi in his body to heal the burns, he also ran the fire crown to burn the sky to absorb the clear qi and fill the sea of qi, and then digested the information that Chi Hong gave him.

This information is the true gasification state and the steps of smelting.

Focusing on his mind, Long Yuan watched carefully, and an image appeared in his mind.

It was the process of transforming and smelting the true qi, but this process was shown to Long Yuan in a more intuitive form.

There are four gases in the closed and transparent furnace in the image, black, silver, red, and gold. Among them, silver represents true qi, black and red represent the impurities in true qi, and gold is metallic true qi. It's just that there is only a little gold in the furnace, and the three gases of black, silver and red are equal.

Obviously, this is an exaggeration, because there can't be so many impurities in True Qi.

Then the black, silver and red gases were mixed, and the word "cooling" appeared in the image.

As the temperature drops, the black gas begins to metamorphose, becoming drops of black liquid. Finally, the metallic true qi collected these droplets to the bottom of the furnace, and the inner bottom of the furnace was opened, and the droplets entered the dark compartment at the bottom of the furnace.

After the bottom of the furnace was closed, there were still four kinds of true qi left in the furnace, gold, black, silver and red, but there was much less black.

Then the temperature dropped, and the silver and red gases turned into liquids.

After reaching a certain temperature, the black liquid in the furnace begins to condense into solids, and is treated by metallic true gas, at this time, the black in the furnace is much less again, but there is still a small amount of black gas, liquid and solid.

Still cooling, the silver liquid turned into a solid, so the red liquid was disposed of a lot.

Immediately after that, the temperature began to rise, and the silver solid turned into a liquid, at which point the black solid was cleaned up, and the silver red became a liquid.

Then all three turned into liquids, and when they heated up again, the red and silver liquid turned into gas, and the black was still liquid, and it was processed out of the furnace again.

At this point, the image is a cycle of transformation and smelting.

"It turns out that this is impurity removal, and it seems that the control of the flame temperature is very high. Long Yuan pressed his temple, feeling that refining weapons was really not an easy task.

The removal of impurities alone is so cumbersome, let alone the subsequent steps.

"And I also had a misunderstanding when I tried it myself before, after the refining of weapons began, unless the refining was completed, the furnace could not be opened, just the dense true qi sublimated on the inner wall of the refining furnace was enough to increase the density of the true qi in the furnace. No wonder the teacher said that the refining furnace needs to be cultivated with true temperature, and the sublimated dense true qi needs to be supplemented by true qi. It's hard. ”

However, Long Yuan was not afraid of difficulties, since he promised the teacher to learn how to refine weapons, he had to do his best. Then he watched the image in his mind many times and pondered it with his heart.

Three days later, after feeling that the burns on his body were no longer serious, Long Yuan began to refine the True Qi Cylinder. Since the teacher didn't give him extra information, he probably still wanted him to think for himself.

Because there was the remaining True Qi material in the refining furnace from the last time, it has now turned into a solid state. Therefore, Long Yuan directly led a trace of metallic true qi into the refining furnace, and then closed all the gas outlets of the Ding furnace with a slight movement, burning at the bottom of the furnace with an inextinguishable flame, calcining the true qi.

After watching the image in his mind, Long Yuan understood that every time the true qi was calcined in the refining furnace, the temperature required for the change would change.

For example, after the first calcination of true gas is cooled, if the true gas can be turned into clear water at room temperature, then after calcining the water to turn it into true gas, it may turn into a liquid state after cooling to 500 degrees.

Therefore, in order to turn these remaining solid true qi materials into clear water and clear qi, an extremely high temperature was required, but this was obviously not difficult for Long Yuan, who possessed the Immortal Flame.

After the refining furnace was once again filled with high-density true qi, Long Yuan began to concentrate on controlling the Immortal Flame and cooling it down.

At this point, Long Yuan knew how difficult it was to take the first step in refining weapons, because the temperature difference between the true qi and the impurities in it was not very large, so Long Yuan couldn't control them from metascaring one after another.

Not once.

Not twice.

Three times no.

......

When Long Yuan made twenty-eight attempts, he finally discovered that there were cloudy droplets of true qi in the gas refining furnace.

Long Yuan was overjoyed, and hurriedly controlled the metallic true qi to collect them slowly, his mind moved slightly, and Long Yuan opened the dark grid at the bottom of the furnace to remove these turbid droplets.

Next, Long Yuan continued to control the temperature of the flame, causing it to drop. According to the information given to him by the teacher, even if it is impurities, the temperature required for the morphological change is different, and it is impossible for all of them to metamorphose before the true qi.

That's why it is necessary to continue to change the temperature and remove impurities.

This was a long process for Long Yuan, because he hadn't realized this before "refining" weapons, so he was very unfamiliar with such operations.

I don't know how many failures I have experienced before Long Yuan discharged some solid impurities.

An hour passed, and Long Yuan felt that this process could not be continued, otherwise his mental power would not be enough to support it until the refining was completed.

Chihong told him that refining weapons needed to be done in one go, otherwise the effect of refining would be affected.

Long Yuan moved his mind to open the hole in the furnace lid, mobilized the metallic true qi into the furnace and wrapped the liquid true qi material, and then led the inextinguishable flame to the lower passage of the stove mouth, controlled it to wrap the metallic true qi, and gently forged it to make it an empty bottle.

The next thing is blowing.

Long Yuan had also seen Uncle Wang build a glass jar in the blacksmith shop, so he followed the cat and the tiger, mobilized the true qi in the sea of qi into the refining furnace, and "blew" the air into the empty bottle.

The heart was divided into two uses, Long Yuan controlled the Immortal Flame and the True Qi on the other, and he was so tired that he was sweating profusely.

The True Qi material was suspended in the refining furnace, which also required Long Yuan to depart a small part of his mind.

The most important thing is that the temperature of the Immortal Flame should not be too high, otherwise the liquid True Qi will turn into gas and escape. That's where it's the most tiring.

Half an hour later, the real gas cylinder cooled down.

Long Yuan was out of breath, and he rested for a full hour before turning the true gas cylinder in his hand, and when he saw the appearance of the real gas cylinder, he felt a sense of shame.

Ugly, ugly, very ugly!

The real gas cylinder was crooked, and it was still bulging on one side, like a pregnant bottle.

Because the glazed vessel needed to rotate during the blowing process to avoid the deformation of gravity, but Long Yuan really couldn't rotate it when refining the true qi cylinder.

"Forget it, wait for the teacher to come and let him point in. ”

Long Yuan continued to enter the cultivation state, now his time is very tight, he needs to hurry up and break through the realm, otherwise it will be in vain when he arrives at Zhaoyao Mountain.

Half a day later, Chihong came to the stone room again, and after Long Yuan opened his eyes, he said, "The true gas cylinder has been refined?"

Long Yuan nodded and turned the True Qi Cylinder out of his body.

"You...... What is refined is ...... Night pot?" Chi Hong checked the true gas cylinder and looked at Long Yuan.

Long Yuan touched his nose, this real gas cylinder was too ugly.

Chihong threw the real gas cylinder in his hand back and said, "Oops, I didn't hold it." ”

Table tennis.

The real gas cylinder fell to the ground and shattered.

Long Yuan's eyebrows jumped, didn't he hold it?

"Didn't quench?" Chihong asked.

Without waiting for Long Yuan to answer, Chi Hong said again: "Continue refining, and figure out how to quench it yourself." Those materials can't be recycled after they leave the body, so take the initiative to find me when you are satisfied. ”

Long Yuan had no choice but to sit down, and after relieving the fatigue of his mind, he began to refine the second true qi cylinder.

This time there were no remaining materials, Long Yuan could only pour the true qi in the sea of qi into the gas refining furnace, and an hour later he completed the removal of impurities, but at this time he was confused, how to quench the true gas cylinder?

Ordinary water or oil cannot be used for quenching, and the true qi that changes its form must be used, and now the only liquid true qi that Long Yuan can get at room temperature is the clear water after refining from the gas refining furnace, or the liquid true qi at the bottom of the gas sea.

However, Long Yuan would not be stupid enough to use the clear water in the sea of qi, which he had worked so hard to cultivate. Moreover, the refined water cannot be put into the sea of qi at all, that is, it cannot replenish the loss of the sea of qi.

So after thinking about it, Long Yuan could only think of the clear water that had been refined.

However, the gas refining furnace has been occupied by the materials used to refine the real gas cylinder, and the temperature inside is relatively high, so it is impossible to obtain the liquid true gas for quenching.

If there is no liquid true gas after cooling, how can the real gas cylinder be quenched?

Long Yuan fell into hard thought and meditation again, and this thought thought for half an hour. Originally, Long Yuan had already spent a lot of effort refining the True Qi Cylinder, but now he had been thinking hard to no avail, and he gradually felt that his mind was weakened and his spirit was sluggish.

"If you can empty the gas refining furnace at this time, calcine the true qi, and then cool it, you can get the liquid true qi. Long Yuan had such a thought.

"That's right! Let the fan making and casting be carried out outside the gas refining furnace, and the gas refining furnace will be vacated to obtain the liquid water for quenching. ”

As soon as he thought of this, Long Yuan opened the gas refining furnace with his mind, wrapped the rough embryo of the true gas cylinder with the inextinguishable flame, and transferred it away from the gas refining furnace.

But as soon as these materials came out of the gas refining furnace, Long Yuan found that it became difficult for him to control the metallic true qi that enveloped the true qi cylinder.

"It turns out that the gas refining furnace has the effect of amplifying the control force. Long Yuan was so tired that his face was covered with fine beads of sweat, and he hurriedly separated an inextinguishable flame to cover the True Qi Cylinder and the Metallic True Qi.

On the other side, the gas refining furnace was sealed again after being filled with true qi, and the blazing flame burned at the bottom of the furnace.

Calcining the True Qi, controlling the Immortal Flame Forging, and invoking the True Qi to blow the form, Long Yuan was single-minded and multi-purpose, and his face and lips were so pale that he was tired.

Finally, he removed the flame at the bottom of the furnace, and after the high-density true qi in it cooled into a liquid state, he sent the true gas cylinder that was about to take shape into the gas refining furnace.

Multiply......

After repeating it a few times, Long Yuan stopped working, and the true gas cylinder should have one step to temper and polish, but he really didn't have the spare energy to carry out this step.

"Still can't do it. Long Yuan threw his heart into the refining furnace, and found that the true gas cylinder refined this time was even worse, the volume inside was very small, and it was a defective product.

After resting, Long Yuan began to return to the furnace and redo it.

Long Yuan intermittently refined it for more than ten times, and finally refined a true qi cylinder that could be seen.

After finding Chihong, seeing the teacher nodding, a smile appeared on Long Yuan's face.
