The room was getting hotter, and even the air between breaths seemed to get a little hotter.

This kind of heat is absolutely unbearable for ordinary people, even if Xu Yi now has a third-level cultivation of the human rank, he still feels quite uncomfortable.

As soon as you breathe in and out, this heat wave seems to pass through the nasal cavity into the internal organs and reach the bones. Not only that, but even his spirit became a little irritable because of this.

Although refining and alchemy both require flame temperature, they are two completely different things.

If the alchemy also encountered such a fire, then the only result would be that all the medicinal materials would turn into a pitch-black paste.

Although Xu Yi's breathing was a little difficult, he didn't have any intention of retreating, and the expression on his face didn't change in the slightest, but stared at Jin Liang's every move.

Unexpectedly, the first time I observed the refining weapon, it turned out to be the level of the earth-level magic weapon, which can be regarded as a special case.

Although the breathing room is very uncomfortable, it is still within the tolerable range. However, after a while, Xu Yi's eyes suddenly changed slightly.

Just when his spirit was affected by the fiery temperature and gradually became a little irritable, from his secret secret dantian, a trace of cold energy was suddenly released.

Under the impact of this energy, Xu Yi seemed to have jumped into a cold stream on a dog day, and the whole person wanted to moan comfortably from head to toe.

What's going on?

There is a planetary visualization in the Ming Shang Dantian, which releases infinite vitality all the time, allowing Xu Yi to obtain great benefits. But secretly the dantian has always been silent, no matter how Xu Yi explores, it seems to be dead silent, and there is no response.

But at this moment, when he was in an extremely hot situation, this dark dantian suddenly moved, and the energy released made him calm down instantly.

Xu Yi quietly realized all this, and after a while, he finally discovered that when the secret dantian released energy to relieve his spirit, it was also constantly absorbing fiery energy.

Xu Yi was amazed in his heart, the fiery energy he felt actually came from the fire pool, which was borne by his physical body. And the upper dantian is where the invisible spiritual power gathers.

One is invisible, the other is tangible, and although both are forces, they are not connected.

But now, the secret dantian has begun to absorb tangible power?

After another moment, Xu Yi suddenly raised his foot and took a step forward.

He wanted to get closer to the fire pool and try the limit of the dark dantian.

"Senior Brother Xu. Deng Ru frowned slightly, and said in a low voice, "The temperature of the fire pool is too high, it is more dangerous for you, stand back." ”

He naturally knew Xu Yi's cultivation, and he also knew how powerful this Gathering Fire Array was, so he was a little worried in his heart.

Xu Yi chuckled lightly and said, "Thank you, Senior Brother Deng, but I want to see it clearly, it's okay." ”

Deng Ru hesitated, stared at it carefully, but after a while, he was stunned.

Xu Yi's face turned out to be calm, without the slightest hint of embarrassment.

Glancing at the raging flames in the fire pool, a thought suddenly appeared in Deng Ru's heart, this fire gathering array will not be a problem. He secretly slowed down the true air, but the next moment he felt the heat rolling in, as if it was about to roast him.

Awe-inspiring in his heart, Deng Ru hurriedly activated his true qi and forced the heat out of his body.

That's right, it's still such a scorching heat, and this kind of temperature can only be ignored by high-level cultivators above the seventh level of the human rank. But Xu Yi ...... Didn't his cultivation just break through to the third level of the human rank?

Stared at Xu Yi again, but no matter how Deng Ru looked, he couldn't find a trace of patience on Xu Yi's face, as if he couldn't feel the boiling heat at all.

How is this possible?

At this time, Xu Yi was extremely happy, he felt that the closer he was to the fire pool, the more active the dark dantian became, and the more heat it absorbed.

This was the first time he had discovered a way to activate the dark dantian, and he couldn't help but be overjoyed.

Although he still doesn't know what the secret dantian is for, since it exists, it is better to figure it out.

Unconsciously, Xu Yi took another step forward.

Jin Liang suddenly opened his mouth and said, "Senior Brother Xu, what are you doing?"

Only then did Xu Yi realize that he seemed to be too close to the fire pool, and his mind was racing, and he said, "Senior Brother Jin, I see that your refining weapon is very interesting, and I want to get closer to observe." ”

Jin Liang glanced at Xu Yi in surprise and said with a smile: "Of course the refining weapon is interesting, since you are interested, then watch it." ”

Xu Yi responded, but he really restrained his mind and looked at it.

Refining, in fact, is similar to the process of steelmaking and alloy refining in another world, which is a process of melting, refining, and re-fuse. It's just that, compared to the steelmaking mill that concentrates countless manpower and material resources, the refining here only needs one person, and a fire gathering array can solve it.

Of course, the laws and force values of the two worlds are different, so there is nothing to compare.

But when Xu Yi really paid attention, he found that refining weapons was really a very interesting thing.

Jin Liang said while smelting: "Now it's just the preliminary refining process, you see that this is a thousand-year-old dark iron, but there are a lot of impurities in it, you need to do this......"

He explained, but he was not satisfied with the movements in his hands, and soon all the materials were passed through the fire pool.

These materials of different materials stayed in the fire pool for a longer or shorter time, but when they were taken out, they all became smaller, and it was clear that some of the impurities in them had been removed by him with exquisite techniques.

Such a miraculous method opened Xu Yi's eyes.

If you want to remove impurities from minerals, it is definitely a big deal. But here, everything seems to be simplistic.

In the final analysis, after all, they are two worlds, and there should be some differences.

It's just that this difference is too big, which makes Xu Yi a little difficult to accept.

Jin Liang's face became solemn, and he said, "Senior Brother Xu, you can drip blood, drop a drop of blood on every material." ”

Xu Yi was stunned and said, "Now?"

"Yes. ”

"Good. Although Xu Yi didn't understand it, he still happily scratched his finger, and then left a drop of blood on each material.

At this time, the residual temperature on the material did not dissipate, and the blood dripping immediately squeaked, and it burned dry in an instant.

Jin Liang snorted lightly, and suddenly took out a giant spoon from the side, and then poured the ingredients into it and placed it in the center of the fire pool.

With his shout, the flames in the pool of fire suddenly rose to a higher level, as if a heat wave that was enough to roast people to death rose into the sky.

"Senior Brother Xu, the smelting has begun, the temperature here is too high for you. Jin Liang's eyes were fixed on the fire pool, and he said, "You go out, and I'll call you when you need to bleed." ”
