"Huoyunfang."

Su Ming raised his head, looked at this large store covering an area of more than thousands of square meters, and walked in with a calm face.

Walking into Huoyunfang, Su Ming walked to the first-level fire room area.

The steward in charge of this area is surnamed Chen, and Su Ming has frequently come here to refine weapons in the past two years, but he is familiar with this steward Chen.

"The old rules?"

Steward Chen, who was sitting behind a wooden table, saw Su Ming and raised his head and asked.

Su Ming nodded, took out the cloth bag from his arms, took out 50 broken spirits, and handed them over.

I saw that Steward Chen waved his hand, put 50 broken spirits into the storage bag, and then threw a wooden plaque, saying: "Twelve hours from now on, don't overtime, overtime will add an extra day to the fee." ”

These are the old rules, and both parties know it in their hearts, but Steward Chen will explain it every time.

Su Ming nodded, took the wooden card, and walked towards the depths of the corridor.

In the hallway, the doors of the fire rooms were closed.

In someone's fire room, a wooden sign is hung.

Su Ming walked to the seventh earth fire room, and a young monk walked out with a calm face.

He glanced at Su Ming, took down the wooden sign of this earth fire room, and walked away.

Seeing the young monk leave, Su Ming hung the wooden sign on the wall outside the earth fire room and walked into the earth fire room.

The next moment.

The stone door of the fire chamber slammed shut.

......

As soon as he walked into the earth fire room, a wave of heat hit Su Ming.

In the center of the fire chamber, a blazing white flame was bubbling out of the hole in the ground, making a snorting sound.

Not far from the fire hole, a control formation is inscribed on the ground, which is the formation that controls the earth fire.

According to their own needs, the monk can control the true qi infused into the formation to adjust the fire, which is very convenient.

Of course, this Earth Fire Chamber is a first-order Earth Fire Room, and the maximum fire can only smelt first-order materials.

If you want to smelt a higher-grade refining material, you have to go to a higher-grade Earth Fire Chamber.

The Blue Light Sword refined by Su Ming was only a first-order low-grade magic weapon, and it was more than enough to use this Earth Fire Room.

Casually glancing at the fire room, Su Ming familiarly took out three steel ingots from the stone lattice on the side.

This kind of steel ingot is called 100 forged steel, and there are 100 layers of lines on it.

Hundred Forged Steel is a benefit given by Huoyunfang to the monks of the fire room in the leased land.

Although the value of the 100-forged steel of ordinary people is comparable to that of the same weight of silver, it is of little value in the eyes of the monks.

However, this kind of intimate service is also convenient for the monks who come to the first-order earth fire room to learn the refining weapon.

Therefore, among the several shops that have opened a ground fire room in Shimizubo City, Huoyunfang has the best business.

After taking the auxiliary materials for refining the Blue Light Sword, Su Ming walked to the formation in the center of the Earth Fire Room and sat cross-legged.

He first took out the iron essence from his arms, then placed the three steel ingots and the iron essence on his thigh, and pressed his left hand on the formation.

With the injection of true qi in the dantian, the fire that emerged from the hole in the ground also continued to change.

Su Ming was familiar with it for a while, and soon found a suitable rhythm for adjustment.

Different earth fire chambers, due to different formations and the strength of the underground fire veins introduced, even if the same true qi is injected, the size of the fire is different.

A mature refiner will be fully familiar with the formation of regulating earth fire before refining a weapon.

Because the size of the fire in the refining process will be directly related to the success or failure of the refining tool, it is very important.

This lesson, Su Ming used a full seven failed refining tools to get it.

From this, it can also be seen how difficult it is to have no one to teach, and only rely on the dead knowledge refining tools recorded in the jade slips.

After all, the "First Solution of Refining" in the jade slip will not tell the person who learns the refining weapon how to familiarize himself with the different earth fire chambers.

"Whew!"

The three steel ingots were held up by Su Ming with true qi and slowly sent into the pillar of fire that was directly bubbling up.

At the moment when the steel ingot came into contact with the flames, Su Ming suddenly adjusted his formation, and the ferocious fire eased.

Under Su Ming's control, this flame seemed to have life, gently wrapping the three steel ingots and smelting them little by little.

No matter how high the quality of the 100-forged steel is, after all, it is just a mundane thing.

Under the calcination of the earth fire, it only took less than half a cup of tea to melt into a ball of molten steel.

Seeing this scene, Su Ming didn't dare to be careless at all, and immediately lifted the iron essence with his true qi and threw it into the flames.

Compared with hundred-forged steel, iron essence, a first-order spiritual ore, is much more difficult to smelt.

It took more than three hours for Su Ming to smelt the iron essence into a small ball of black molten metal.

Then, he slowly fused the molten steel and the black molten metal together.

This process is very short, and it is also the second difficulty of the four major steps of refining.

Fortunately, Su Ming had refined the Qingguang Sword more than twenty times, and he was already very familiar with this process.

The refining and fusion all passed smoothly, but there was no joy in Su Ming's eyes.

Because the three steps of refining, fusion, and shaping are not difficult for him, and the real difficulty he encounters is the inscription of the formation.

Half an hour later.

Su Ming's true qi had already consumed most of it, and he had finally completed the shaping of the Qingguang Sword.

The last step is the inscription pattern that he has always failed.

The Qingguang Sword has a total of four formations, which belongs to the average quality of the first-order lower-grade magic weapons.

Su Ming didn't dare to choose a complex magic weapon to refine, and even so, he still failed twenty-five times in a row.

Soon.

The first and second formations were engraved by Su Ming on the blade of the Qingguang Sword.

Next, there is the third level.

And the third formation pattern is where he failed last time.

"I don't know if I was right last time."

Su Ming was a little apprehensive in his heart.

But when it comes to this point, I can only rush forward.

Based on the experience summarized last time, as well as the solution that he came up with after analyzing the failures, Su Ming finally succeeded in inscribed the third formation pattern on the sword embryo of the Qingguang Sword.

Seeing the third layer of formation patterns covering the first two layers of formation patterns, Su Ming's heart suddenly rejoiced.

But in an instant, he adjusted his mentality.

Now is not the time to be happy, the blue light sword has not yet been successfully refined.

Su Ming knew that if he didn't succeed this time, it would be difficult for him to have the next chance to refine the magic weapon.

Because his spirit stones are about to run out.

The fourth formation pattern kept flashing in his mind, but when it came to the real inscription, there would always be such and such accidents.

This is the gap between theory and practice.

Only this time, I don't know if it was the pressure of death, or the accumulation brought about by his two years of conscientious refining.

Su Ming actually succeeded at one time, and engraved the fourth formation pattern on the sword embryo of the Qingguang Sword.

As the fourth formation pattern covered the first three formations, the entire blue light sword flashed, and all the formation patterns disappeared, hidden under the sword body material.

There was only a three-inch-long blue light sword left, which was lifelike in front of Su Ming.

"Success?"

Su Ming was stunned for a moment, and then his face showed ecstasy.

He knew in his heart that the successful refining of the Qingguang Sword meant that he would be able to gain a complete foothold in Qingshuifang City.

Even if he no longer goes out of Qingshuifang City to buy goods for sale, he can still pay the rent of the T-shaped No. 19 shop, and even earn a certain amount of spirit stones for cultivation.

Thinking of the bright future in the future, Su Ming felt that the two years of his painstaking study of refining tools were all worth it.

Stop injecting true qi, and the earth fire retreats.

When the Qingguang Sword cooled down, Su Ming trembled and stretched out his right hand and held the hilt of the Qingguang Sword.

Just as he grasped the hilt of the Blue Light Sword, a message flashed through his mind.

"Found a first-order lower grade magic weapon, did it decompose?"

"Huh?"
