Only after becoming emperor did he realize he was in a fantasy world of immortal cultivation.

Two hours later, Lin Yuan left the spirit chamber and went to the weapon-refining room.

He walked to his usual spot and sat cross-legged beside the dark and ancient forging furnace, with a finely woven meditation cushion beneath him.

Then he took out a piece of refining material from his storage bag and threw it into the refining furnace.

He lit his spiritual fire and began studying the day's lessons.

"go."

He gave a soft shout, and the refining materials fell into the furnace.

With a flash of inspiration, the array already engraved on the bottom of the furnace was activated, and a cluster of bluish-white spiritual fire shot up with a "poof," quickly enveloping the ore, and the temperature in the room began to rise.

Lin Yuan calmed his mind and began to practice the "refining" and "deep purification" techniques that had been emphasized in today's weapon-refining class.

He first used the time it takes to drink half a cup of tea to preliminarily smelt the copper ore, the material for refining weapons, with a steady "civil and martial fire," separating out most of the obvious associated ores and impurities, and obtaining a mass of dark red, still somewhat turbid, molten metal.

This step was relatively easy, and he completed it smoothly.

Next comes the more refined and challenging "deep purification".

It requires transforming spiritual energy into an extremely fine "sieve" or "carving knife," and using precisely varying flame temperatures to remove or transform tiny impurities of similar properties that are molten into the metal, so that the material reaches a state close to a pure, single attribute.

Lin Yuan was completely focused, recalling the key points from the class, manipulating the spiritual fire to varying degrees, his spiritual power like the most nimble fingers, carefully combing through the high-temperature molten metal.

However, no matter how he adjusted it, whenever the purification process reached the final stage, just as the molten metal was about to turn a pure crimson color, a very slight fluctuation would inexplicably occur, causing the purity to never reach the ideal standard, ultimately resulting in failure.

The furnace fire went out, and a piece of red copper ingot, whose purity barely reached "good" but was far from "excellent," was taken out and set aside, signifying yet another failed attempt.

Lin Yuan did not immediately begin the next step. Instead, he frowned slightly, closed his eyes, and focused his mind, meticulously replaying all the operational steps, temperature changes, and the timing and force of the spiritual energy intervention in his mind, as if retracing a painting.

"The steps are correct, and the temperature changes are done in the safest, gradual way... The control of spiritual power is also quite precise..." he muttered to himself, eliminating a few common errors.

So, where does the problem lie?

His thoughts fell on "perception".

In the purification process and all subsequent steps, weapon refiners rely not only on experience and techniques, but also, to a large extent, on precise perception of the real-time state of the materials inside the furnace.

The "Microscopic Perception Technique" he cultivated was one such method, which allowed him to penetrate materials with his divine sense and "see" their internal structure and energy flow to a certain extent.

This skill is easy to learn, but the level to which one can master it varies from person to person.

After using this technique, Lin Yuan was able to clearly sense the composition of the materials, but this was under the condition that the temperature of the spiritual fire did not change much.

Therefore, he had very meticulous control over the spirit fire during the purification process.

But it still doesn't seem to be enough.

He needs to further refine his perception techniques.

After thinking it over, he lit the furnace again, but instead of adding new materials, he put the copper ingot that had failed to be refined back into the furnace.

Of course, this time the focus is on refining perception techniques.

He deliberately slowed down the entire process, focusing most of his attention on the operation of the "Microscopic Perception Technique".

Time slips away quietly in the midst of intense focus.

Half an hour later, Lin Yuan's tightly closed eyelashes trembled slightly, and the corner of his mouth moved almost imperceptibly.

Become!

Just now, in a brief moment, his perception seemed to break through an invisible membrane and suddenly became much clearer!

He not only "saw" the core of the most troublesome impurities, but also vaguely "predicted" that when the flame temperature increased by a little, the bonding force between one of the impurities and the main metal would have a brief "loosening window".

Although this is only progress on a relatively simple waste, it is significant.

This means that his perception skills have begun to touch the threshold of "dynamic prediction".

Suppressing the slight joy in his heart, Lin Yuan knew that only through practice could he solidify his understanding.

He took out a brand new, higher-quality but more complex piece of "cold iron associated ore" from his storage bag and put it into the furnace.

This time, he will apply his newly refined perception skills to the actual purification process.

Inside the weapon-refining room, the flickering fire illuminated Lin Yuan's calm and focused profile.

Outside the window, the moon quietly climbed to its zenith, casting its clear light, before gradually setting in the west and disappearing behind the distant mountains.

The only sounds in the room were the faint crackling of the fire burning in the stove, and the occasional soft noise of the stove lid being opened, or materials being added or removed.

Lin Yuan was completely immersed in this cycle of repeated practice, verification, adjustment, and more practice.

The sky gradually changed from deep black to indigo, and then the east began to lighten with the first hint of dawn.

As dawn broke and the first rays of sunlight slanted through the high window into the weapon-refining room, casting bright spots of light on the stone platform filled with tools and materials, Lin Yuan slowly opened his eyes.

Although there was a hint of fatigue from staying up all night in his eyes, there was more of a calm and content look in them.

With a gentle wave of the hand, the stove lid opened with a click.

There was no dazzling light, nor any intense fluctuation of spiritual energy.

A solid mass, about the size of an infant's fist, with a soft and pure moon-white hue, floated gently out of the still-warm furnace and hovered in front of him.

This substance was of uniform texture, with a restrained luster, and felt slightly cool to the touch. It exuded a pure, cold iron aura, without any impurities or impurities.

Deep purification—

Complete success! The quality has reached "Excellent" level!

Lin Yuan's clear black and white eyes gazed at the culmination of his night's hard work, and unmistakable joy finally filled his eyes.

"It's done."

However, just as he was about to put away the materials and take a short rest, the token on his waist that represented his identity as the head of the weapon-refining hall suddenly lit up with a steady dim light without warning, and emitted a continuous warm sensation.

Lin Yuan raised an eyebrow and ran his hand across the surface of the token.

As spiritual energy was injected, a line of simple yet urgent words immediately appeared on the smooth surface of the token—

Captain of the Guards, outside the Dharma Transmission Hall, two disciples from a collateral branch got into a fight. We went to stop them but failed, and we were all caught in the crossfire and injured.

Lin Yuan glanced at the entire place and immediately cast a spell to leave.

When he appeared at the entrance of the Dharma Transmission Hall, his gaze swept across the area.

Then they saw two teenagers fighting fiercely not far away.

His men, meanwhile, lay on the ground clutching their chests and groaning in pain.

He looks quite badly injured.

Lin Yuan turned his gaze back to the two who were locked in fierce combat.

Upon seeing him, several of his men struggled to their feet and ran toward him.

"Greetings, Chief Guard Lin," the group said in unison, bowing.

Lin Yuan lifted his eyelids slightly, looked at one of them, and asked, "What's going on?"

The man quickly replied, "Reporting to Guard Captain Lin, after the lecture at the Dharma Hall today, I heard two people arguing about whose magic was stronger, and then I saw them start fighting."

The Gong Clan allows its disciples to spar with each other, but they must find the right place.

Lin Yuan's eyes turned cold.

If these two really fight and something serious happens, he'll inevitably have to go to the court of law enforcement.

At this time, more and more disciples gathered around to watch.

"What should we do now? These two are both at the third level of Qi Refining, and the swords they wield are also extraordinary. They are currently fighting with all their might. It will be very difficult to stop this fight without injuring either of them."

"I think we should try to persuade them a bit. They probably know that if such a private fight is reported to the court, they will definitely suffer the consequences."

"You know the nature of these twins. Once they start talking about fighting, they'll definitely try to determine who's better. They won't listen to anyone else."
