When the wood dust entered, Hu Lao didn't seem to notice it, he was still immersed in his own small world, watching the experience of the fourth-order refiner, picking up the fragrant tea from time to time, taking a sip, and smiling constantly on the corner of his mouth.

Mu Chen could feel that Hu Lao's loyalty, love, and dedication to refining tools together. Smiling, calm and respectful, he stood beside Hu Lao, and naturally took the pu fan to enjoy the cool for Hu Lao.

Hu Lao generously put the fourth-order refining experience and his own understanding on the table for Mu Chen's enlightenment.

Mu Chen watched, unconsciously frowned, and the center of his eyebrows was twisted into a Sichuan shape.

Looking at a stick of incense, Mu Chen sighed and shifted his eyes elsewhere. This fourth-order refining experience is rough and full of mistakes, and it is completely incomparable with the fourth-order refining experience in the sea of wood dust.

According to this experience, the fourth-order magic weapon that is refined is the strongest, but at the peak, the material cannot be maximized, and due to impurities and other reasons, it will never be able to be promoted to the semi-spirit treasure, unless it has a great opportunity.

Although Hu Lao pointed out some mistakes and added his own opinions, the number of mistakes picked out was not large, and the "method of correction" seemed to be correct, but in fact it was on another detour.

Mu Chen is in the sea of knowledge, combined with the fourth-order refining experience given by the painter system, corrects this experience, and slowly condenses the spiritual knowledge card.

"Huh?"

Hu Lao noticed Mu Chen's sigh, felt Mu Chen's emotions, and was unhappy in his heart. The experience in his own hands came from 10,000 years ago, when the art of refining weapons was inevitably rough and could not grasp the essence, but it was the wisdom and essence of the sages.

If there is no wisdom of the sages, how can you progress the art of refining today, as soon as he thought about this, Hu Lao decided to assess the wood dust, weigh his ability, and assess his conduct.

If the character is misbehaving, then no matter how talented he is, Hu Lao will not teach it.

"Mu Chen, look here: Refining the fourth-order magic weapon: Taishan Yin, why do you need to cut the main material, divide it into two, and refine it gradually?"

Hu Lao spoke up and asked Mu Chen a simple question to assess Mu Chen's basic skills. Although this question is not difficult, there are misunderstandings and it is very easy to go astray.

Mu Chen was stunned for a moment, stopped shaking the fan, and answered Hu Laozhi's question seriously and affirmatively:

"The reason why it is dissected is because the main material: the soul stone of Mount Tai is so powerful that it can capture the essence of the rest of the materials, so it needs to be weakened, otherwise it will not be able to refine the weapon. ”

Mu Chen's answer was decent, straight to the point, and Hu Lao nodded quietly. However, Mu Chen's words did not end, and continued to speak:

"However, it is really inappropriate to dissect the method of refining the soul stone of Mount Tai. Fourth-Order Peak Material: The Soul Stone of Mount Tai is one of the few fourth-order materials with spirituality, and if it is dissected, the damage to its spirituality is too great, and it even disappears completely. With this refining weapon, the power of the finished Taishan Yin can retain a maximum of seven points, which is far from reaching the peak. ”

Hearing Mu Chen's opinion, Hu Lao nodded secretly, and his evaluation of Mu Chen was even better.

This is the drawback of this law, but no one has been able to change it for 10,000 years. If the magic weapon is refined with the complete Taishan Soul Stone, then the magic weapon cannot be formed at all between the spiritual troubles.

"Hu Lao and Mu Chen have a way to solve this drawback. At the beginning of the refining process, the spirit is conceived and raised, so that it can be elevated to ignorant consciousness. Then he uses the Law Decision: the Blue Technique to communicate and control this Dao consciousness, so as to reach the point where it cannot be interfered with.

In this way, the magic weapon of Mount Tai can not only exert 100% power, but also be directly promoted to a semi-spiritual treasure, and have the opportunity to be promoted to a spiritual treasure. ”

Hu Lao wanted to interrupt Mu Chen and start the next assessment, but Mu Chen spoke again, Hu Lao could only wait, and after listening to Mu Chen's narration, Hu Lao's eyes lit up, and he calculated in his heart.

Cultivating spirituality and controlling this method was once proposed, but it was rejected because it was too difficult to operate. But the appearance of the blue technique opened a window for Hu Lao.

The blue technique is extremely unpopular, and it can improve the tacit understanding between monks and spirits. It is useless in the half-spirit treasure, and it is useless in the spirit treasure. Therefore, there are not many monks in the primordial and distracted stages who know this magic, and even if they have studied it, they will forget it.

Seeing that Hu Lao's heart moved, Mu Chen took out the soul stone of Mount Tai from within the cave, and took out the specially blended five elements solution that can improve spirituality, and improved the weak spirituality in the soul stone.

After some operation, Hu Lao determined in his heart that this method was feasible.

"Mu Chen? This method is understood for you? or is it?"

"Students come out on their own. ”

Surprised, Hu Lao thought for a few seconds, and asked again:

"Mu Chen, refining the fourth-order magic weapon: Great Xia Dragon Sword, how can you ensure that you refine one step?"

This problem is slightly out of the way, and the difficulty increases, which tests the refining weapon of wood dust even more.

"Dragon Sword, the main material is the fourth-order demon beast skeleton that carries the blood of the dragon clan, according to the different bones, the method of refining is different, and the magic weapon is called the Great Xia Dragon Sword?

To quench this spine bone, you can't use earth fire, you should use a special flame of the fourth order: Qinglian fire, first Wen and then Wu, with the Jade Dragon Liquid, Sanjin Minghu ore, according to the following steps, quenching, which can ensure the perfection of the Great Xia Dragon Sword and quenching this step to the greatest extent. ”

After listening, Hu Lao's heart felt like a river and a sea. I have never heard of this method as Mu Chen. However, the soul runs and calculates, and the wood dust method is more scientific and advanced, almost close to perfect refining, and retains the perfect attributes of the keel.

Compared with the method recorded in Hu Lao's knowledge of the sea, Muchen's method is completely successful.

"How do you know about this method?"

"You asked earlier, the student combined his own experience, calculated, and answered, the specific method? The student has not yet experimented, I don't know if it can be done. ”

Mu Chen's slightly shy answer, his tone was not high, and he didn't seem to be confident.

The word 'genius' appeared in Hu Lao's heart for no reason.

"Mu Chen, the last question, refining the fourth-order peak magic weapon: the Blue Sea Towering Heavenly Tree, the main material: the Blue Sea Tree, the Towering Heavenly Tree, how can it be perfectly integrated together without any flaws?"

This problem was a problem that Hu Lao had just encountered when refining this magic weapon a few days ago, and he couldn't solve it, so he flipped through the experience of the fourth-order refining weapon, trying to get the answer.

The Tree of the Blue Sea is a tree that grows beneath the surface of the sea and has a strong water attribute, while the Tree of the Sky is a tree that grows next to magma and has a strong fire attribute. Fire and water are incompatible.

According to the drawings, Hu Lao carried out refining, but the two were mutually exclusive, and they could not be fused at all, and forcibly fusing could only lead to a great reduction in the power of the magic weapon refined, or even inferior to the third-order magic weapon.

If Mu Chen's ability to answer this question is to prove that Mu Chen's alchemy technique surpasses that of the Fourth Order.

Mu Chen fell into deep thought, combined his experience, and pondered the answer.
