The study of weapon refining is not as interesting as practicing, at least in Jiang Xin's opinion.

The change of materials, the distribution of Qi, the concentration of energy, every aspect requires Jiang Xin to focus on.

When the old man was refining the weapon, everything seemed to be smooth and easy, but when he got to the center of the river, various problems began to emerge one by one. But without enough talent, he would not even be able to detect the emergence of these problems.

This is like a century-old problem in the field of mathematics. Outsiders may know that it is difficult, but only people in this field will know exactly how difficult it is. If you don't get started, you won't even have the opportunity to discuss it.

Just like he had just started learning clay sculpture, Jiang Xin was now like an ignorant apprentice, starting a new learning journey. The meaning of the existence of problems is for people to solve them, and every time a problem is solved,

Everyone can get an inexplicable motivation from this, and this is also a major motivation for Jiang Xin to persevere and keep learning.

Changes in material combinations, the distribution of Qi, and the impact of external pressure on the internal changes of the utensils. Although the essence of weapon refining is still Qi, various auxiliary means should not be underestimated.

Jiang Xin is like a sponge absorbing the water that symbolizes knowledge, which can't help but make the old man feel a sense of admiration and love for talent.

But as time continued to pass, as the sun rose and the moon set, watching Jiang Xin change from being helpless at the beginning to being successful in just a day or two, the thoughts in his heart began to waver.

:Genius, can you really do this?

As far as he knew, even the apprentices in Tiangongtang who had studied systematically were always as difficult as apprentices when it came to weapon refining during epidemic prevention, and almost everyone was unable to do it like Jiang Xin, who only had a few short seconds.

Such a huge transformation can be accomplished in just a few days.

Seeing the sword in Jiang Xin's hand flashing continuously, just fluttering around for a while before creating a garden one by one and assembling it into parts, the old man was a little speechless for a moment.

As an object that can try to reflect the number and distribution of enemies and friends, Guanyuan can actually only be regarded as a somewhat flawed magic weapon. It needs to be paired with another detection component to be a complete magic weapon.

But even so, Guanyuan is not that easy to make. What Jiang Xin is making now is just a mold. The rest, using Qi to refine it into a magical weapon is the real priority.

"Master, that's it." Jiang Xin placed several molds that had already been formed on the table, then turned around and interrupted the old man's meditation, asking him to return to the state of mind.

He reached out and picked up the Guanyuan on the table and looked at it. The old man looked at it for a long time but could not find anything wrong with it. He sighed in his heart again: "Okay, you have mastered this method, and the real highlight is next."

"The highlight." When Jiang Xin heard this, he immediately cheered up and said, "You tell me."

But what surprised Jiang Xin was that the old man shook his head: "This thing can only be understood but cannot be expressed in words. At least, old man, my level is not yet at that level. If you insist on saying it, it is a little imperfect after all."

"What do you mean?"

"Your master, I will show you slowly. Keep your eyes wide open and watch carefully. Don't let go of anything. Do you understand?"

"Understood." Jiang Xin nodded, and then with a flash of light in his eyes, he took in the whole body of the old man: "Okay, master, you can start."

"You don't need to rush me, kid." The old man taught him a lesson, and then he slowly calmed down and picked up the Guanyuan on the table and began to use it.

A burst of vitality radiated from the old man's body, wrapping the garden inside like soft flowing water, slowly exploring inward inch by inch.

Unlike the imperial objects or even the chemical objects, although the Qi in the refiner looks as docile and non-attacky as running water, its degree of infection is far greater than the first two.

More and more energy flows into the garden, like a thin film that completely covers every component inside and outside the garden, transforming it step by step from the outside in.

Guanyuan is like a piece of 'pig iron' containing many 'impurities'. It becomes purer and purer after being washed by the Qi breath. The response to the Qi breath is amplified and deepened little by little...

"Do you understand?" Suddenly he stopped what he was doing, and the old man looked at Jiang Xin, his eyes full of expectation: "Do you understand what I just did?"

"I understand..." Jiang Xin nodded hesitantly, and then saw the old man placing another piece of the garden in front of him: "Here, let's demonstrate."

"Oh." Jiang Xin was a little unsure, but she still reached out and took it, imitating the old man's previous movements, changing the Qi breath in her body into a smooth and smooth shape, filling the garden from the outside to the inside, and then removed it.

The indescribable 'impurities' make it an excellent carrier of Qi.

But most things are not always as smooth as they seem. The word "impurity" does not describe the actual material in reality, but an abstract existence like Qi. There are thousands of people with Qi, and the same is true for "impurities".

Just when Jiang Xin was using her best strength to completely clear the 'impurities' in the garden, the old man's voice rang again: "Okay, stop."

"What's wrong?"

"You did it wrong."

"Wrong?" Jiang Xin was a little confused: "Isn't this step just to remove those 'impurities' that don't exist?"

Hearing the words 'useless impurities' spoken by Jiang Xin, the old man's face twitched, and then he explained: "That's not called 'impurities', that's called characteristics."

"Human beings have heart, fire, lungs, gold, kidneys, water, liver, wood, spleen, earth, and five qi. The heaven and earth also have the power of yin and yang and the five elements to produce each other. Everything exists for a reason."

"People have negative emotions such as sadness, anxiety, anger, etc., but can we say that these negative emotions are impurities in people's hearts and should be removed? No."

"Emotions are ever-changing, but it is precisely because of these ever-changing emotions that all living beings in the world are unique."

"The 'impurities' in your mouth are just like these emotions. Although removing all the impurities will make the material pure, it will actually completely lose its characteristics, which is not advisable."

"So what I need to do is to screen out the traits I need, and then remove the rest?" Jiang Xin pondered for a moment: "But how can I distinguish which of them are the traits I need?"

"So that's your first real test, figuring out which qualities you need."
