Lou Muyan followed elder martial brother Lu into an underground refining room and felt the heat blowing on his face.

She looked around, and there was ground fire under each refining room here. The disciples of the refining institute could not only use the power of ground fire, but also improve the success rate.

Yan Jun knew they came in, but he didn't speak. He kept staring at the holy treasure in the refining furnace with mental strength, and drops of sweat fell from his forehead.

He is a third grade refiner. Recently, he found the bottleneck of the fourth grade, so he has been trying to refine holy treasures in order to break through.

This is the last piece of material he prepared for refining the holy treasure. If he fails again, he may have to step back for some time.

Elder martial brother Lu, as a disciple of the refining Institute, is also a third grade senior refining master, but he didn't expect that this younger martial brother would break through the fourth grade.

Such a talent is unmatched by few core disciples of the inner school. No wonder the Dean attaches so much importance to Yan Jun.

He glanced at the refining furnace in front of Yan Jun and gradually revealed some pity. Although he didn't understand why the holy treasure refined by Yan Jun would go wrong at the critical time, after all, he hadn't reached the level of four grades, but he still felt the energy that was about to explode.

Lou Muyan went to Yan Jun, touched his chin and looked at the refining furnace. Suddenly he said, "there's a problem with your fire control. The fire is too big. Turn it down by one third."

Yan Jun didn't expect Lou Muyan to say this to him. Originally, the prepared materials were scrapped. Now, listening to her words, he also had the intention of trying, so he reduced the fire control by one third.

What he didn't expect was that the firepower was small, and the power that could not bear the explosion was weakened. But according to the common sense of weapon refining, his previous firepower was right?

"The jade crystal contains a very gentle water element, which needs to be evaporated slowly with medium fire. Your previous fire is too big to directly roast it, so the refining of the holy treasure failed." Lou Muyan explained when he saw that he was puzzled.

Elder martial brother Lu changed his look and asked, "if the firepower of the refining device is reduced at this time, the hardness will be affected when it is finally formed, and it will not reach the grade of holy treasure."

If the final result becomes a sacred vessel, there is no significance of ascension.

Yan Jun had the same question in his heart. While controlling the intensity of the flame according to Lou Muyan, he looked at her for advice.

"Who stipulated that the last flame of the smelter must be a big fire? The fire requirements below the fourth grade are almost due to the materials of the smelter. The materials for refining the holy treasure are very different from those for refining the third grade holy ware before you. You didn't find it?" Lou Mu's face was a little serious.

Yan Jun immediately felt that he had grasped something. "Do you mean that the smelters with more than four grades control the heat according to the materials?"

"Not only should the fire be controlled according to the material, but also the properties of the material should be understood."

"It's like this holy treasure you're refining now. The properties of jade spar and bright emerald glass are completely opposite. If you add some vanadium powder and the lower two properties, even if you use the heat just now, you won't almost burst like this."

"If you do not add neutralized materials, you need to control the degree of firepower, so you must know the properties and characteristics of refined materials."

"Also, you should feel the changes of each material in the process of refining and integration with your heart, and turn them into a part of you, as if you would melt yourself into it, and you would definitely break through the four products." Lou Muyan thought for a moment, and still mentioned a few words.

Yan Jun's eyes lit up and asked, "now I feel that jade crystal is much more harmonious with other materials after removing water elements, and Mingcui glass is beginning to soften. Should I increase my firepower now?"

"Smart, go to the refining and shaping stage according to your feelings. Don't bring into the fixed thinking of refining sacred vessels. The highest state of refining vessels is to understand them with your heart." Lou Muyan turned and walked to a chair not far away and sat down without prompting.

Different from alchemy, spiritual tools are made by alchemists. Each piece has different attributes, shapes and uses. There are only methods, no prescriptions, and you need to deeply understand it.

Yan Jun closed his eyes and suddenly felt a sense of enlightenment in his brain.

He wholeheartedly put his mental strength into the refining furnace, felt the changes of materials in the furnace, controlled the fire and integration according to his understanding and experience of materials, and gradually indulged in a strange state.

Elder martial brother Lu also kept staring at the refining furnace to observe the changes. His eyes were sometimes confused and suddenly enlightened.

An hour later, the refining furnace made a crisp sound, and a cyan light came out of it.

As soon as Yan Jun grabbed it, a blue Bracelet fell into his hand.

Although the bracelet does not have too much decoration and looks ordinary, it vaguely exudes a faint sense of introversion.

"Really!" after refining this defensive bracelet, Yan Jun's state of mind also changed greatly, and the fourth grade tool refiner came naturally.

Lou Muyan chuckled: "congratulations on becoming a fourth grade weapon refiner. You are the first one to reach the fourth grade in the outer door's weapon refining yard."

"Thanks to your guidance, I can become a fourth grade tool smelter today." Yan Jun's eyes were filled with gratitude.

Without the Enlightenment of Lou Muyan, he may not be promoted to the fourth grade in a few years, because he has entered a dead end.

No wonder there are so few weapon refiners with more than four grades, and they generally don't easily explain their experience to people. It turns out that they want to understand the true meaning of weapon refining by themselves.

Lou Muyan smiled carelessly: "it's all your talent!"

Elder martial brother Lu was also very excited at this time. After listening to Lou Muyan's words just now, he also had the feeling of grasping something. He believed that he could touch the barrier in time.

"Younger martial sister Lou, listening to your words is better than reading for ten years. Even the elder of the tool refining academy has not instructed us. Are you also a high-quality tool refiner?"

If you are not very familiar with refining tools, how can Lou Muyan instruct Yan Jun to refine holy treasure level magic tools?

In particular, she was more familiar with the refining materials than those of them, which shocked him and impressed him.

"I heard it too. It's good to be useful to you." Lou Muyan smiled faintly and obviously didn't want to say more.

When Yan Jun saw that she avoided and didn't want to say, they both tacitly stopped asking. Elder martial brother Lu looked at Lou Muyan thoughtfully and recorded the guidance in his heart.

"Mu Yan, what's the matter with you coming to me today?" Yan Jun asked with a beautiful radian pouring out of his thin lips.

He is now sure that Lou Muyan is definitely a tool refiner, and the level is not low. What little monster is this woman? And she won't?

Now is not the time to ask her. When he has a chance, he still wants to talk to her about his experience in refining utensils.

Lou Muyan nodded: "are you familiar with the commercial street?"

"Commercial street? I've been there several times, but I don't know much." Yan Jun thought about it and replied.

"Just go there. If you're ok now, can you accompany me to the commercial street?" asked Lou Muyan.

"It's all right. It's my honor to go shopping with the beauty." Yan Jun joked.

Lou Mu gave him a white look. "It's getting late. Let's go."

"Younger martial sister Lou, I'm familiar with the commercial street. If you don't mind me taking you there?" Lu Qian said with a smile.

He became more and more curious about the younger martial sister who was famous in the outside world. Taking her to the commercial street was a little reward for the advice just now.

"OK! Please, elder martial brother."

There is a deacon disciple of the court. It can also save a lot of trouble. The labor sent to the door is not in vain.
