"Soul power and spiritual power?" Feng Jin wondered, he didn't understand why the refining weapon needed soul power and spiritual power, these were two completely unrelated things, wasn't it?

"Why are you so confused?Then how do you think the refiner should refine the weapon?" Yan Liefeng saw Feng Jin's doubts at a glance, but he didn't explain, but asked Feng Jin rhetorically. “...... Aren't they the three main points?" Feng Jin remembered what Yan Liefeng had just said, there are three main points in refining weapons, and now he asks how to refine them, they should be those points!

"Then tell me, why do you have a fire control technique?" Yan Liefeng shook his head and sat on the ground, not caring if the ground was clean or not, anyway, he was often bombed and there were few clean clothes. "Because some materials require different temperatures and heating areas...... Is soul power and spiritual power used to detect?!" Feng Jin woke up violently, how high is this temperature at different temperatures?How big is the heating area?How can I grasp it if it can't be detected?

"That's right! The refiner needs to pay attention to the changes in the materials in the dingzhong at all times, and the spiritual power used is used, so every time the refining of a spiritual weapon refiner consumes a lot of spiritual power; if there is no strong spiritual power, the refiner may exhaust the spiritual power and become a waste person in the refining. Therefore, in order to become a refiner, one must have excellent mental strength. ”

Feng Jin nodded in agreement, and then remembered another thing Yan Liefeng said, "What about soul power?" "Soul power and spiritual power complement each other, it can be said that the stronger your soul power, the stronger your spiritual power will be, so some people directly refer to soul power as spiritual power, do you understand?"

Feng Jin was originally a little worried about whether he would become a refiner, but after he listened to Yan Liefeng's words, he was not worried. He is a person who has been reborn once, and the soul of his previous life is fused with the soul of this life, and it is impossible for his soul power to be weak, so it is basically a certainty that he will become a refiner.

"This is a fire control book, I don't know the name or what, you read it in three days, and then start fire control on the fourth day. There's also a copy of the Materials, and you can refer to this book to give me all the materials here! I'm going to check it. Yan Liefeng took out two thick books and handed them to Feng Jin, ignoring his frustrated face and patting him on the shoulder, he was about to walk out, "Is this fire control technique a little thinner!" Feng Jin instantly felt a lot of pressure, can he really read and learn the fire control technique like a brick in three days?

"There are also those that don't require fire control techniques. Yan Liefeng stopped and turned around and said seriously, but the smile in his eyes betrayed him, "Really?" Feng Jin's tone was full of disbelief, Yan Liefeng, who had a criminal record, had zero credibility in Feng Jin's place. "Just go find the fire that connects with your heart. Come on, I'll support you mentally!" Yan Liefeng said with a smile, looking at Feng Jin's frustrated expression, he said that he was in a good mood.

In fact, the spiritual fire is not only the fire cultivated in the cultivator's body, but also the spiritual fire cultivated by spirit beasts and spiritual plants, and the spiritual fire is the general name for all the acquired cultivation.

Although the fire that you cultivate is connected with your own mind, this kind of fire is too weak to be used for refining, and it takes not only a lot of time but also chance to cultivate this kind of spiritual fire into a fire that can refine weapons. Although the refiners knew that the spiritual fire they cultivated could save them from complicated fire control techniques, few people would do this, just because their cultivation was too difficult to cultivate. Therefore, the spiritual fires used by refiners are usually flames that have already been cultivated and matured by other creatures.

Other fires that are not cultivated by oneself can actually be connected with the mind and spirit, but this requires obtaining the flame core or seed of these flames, and fusing one's spiritual power with the flame core, or putting one's own spiritual imprint on this flame, so that it can be connected with the flame heart. But how many people dare to do this, to put a mark on the core of the flame that is more terrifying than the flame, this is basically a move to kill and live, so unless luck is against the sky, no one dares to do this.

...... Three days later

"You've learned the trick of fire control, let's get started. "Yes!" Feng Jin was a bitter tear when he mentioned this! After three days of sleepless study, he even stopped practicing every day, so he barely finished learning the fire control technique, you must know that he has not been promoted since he reached the second level of foundation building, which means that he has not been promoted from Chize Town to Zhang Zhoucheng. In this case, he stopped his cultivation to learn the fire control technique, which shows how hard he worked.

"You're only in the foundation building period now, and the fire control technique is even more important for the foundation building period. Cultivators in the foundation building period can't control their spiritual power yet, and they all rely on the fire control technique to drive their spiritual power, so you must memorize every step of the fire control technique. Well, condense this fire into shape, that's your job. Yan Liefeng lit the firewood, the orange flame jumped up, he pointed to the fire and said, and then sat on the side and watched Feng Jin's movements, he still had some small snacks in his hand, obviously planning to watch.

Feng Jin closed his eyes, recalled the fire control techniques he had learned in the past three days and went through it in his mind, and then opened his eyes and looked at the flames in front of him.

"To operate spiritual power, first set the fire. Feng Jin silently recited the order of casting in his heart, and more than a dozen handprints were formed on his hands. The reason why the fire control method is so thick is because it often takes a dozen or dozens of handprints to complete an order, so it is possible to get thousands of handprints down the whole set of methods, so the speed of sealing has also become a key to fire control. The flame is unpredictable, and if the sealing speed is slow, it will not be able to keep up with the changes and the fire control will fail, so the sealing speed is also a necessary course for a refiner.

"Then there's control. "The first part of the fire is not dangerous. To set the fire is to stabilize the flame to a level that the refiner can control. This link is particularly important, if the flame bursts directly into the start, it is easy to lead to failure, not to mention, it will also explode, so the fire is an absolute process to do. After fixing the fire, it is controlled, and the control begins to increase the output of spiritual power to achieve the purpose of using the flame for its own use; during this period, you can't be in a hurry, otherwise the stable flame will burst again, and this time the fire control will fail.

"It's not good, the output of mental power is fast!" Feng Jin noticed that the stable flame had a tendency to burst again, and immediately adjusted his sealing speed to control the output speed of mental power, but this was not easy, and from time to time it would be uncontrollable and fail, so Feng Jin's forehead was full of sweat. The command of control has not been completed, but the flames burst Unless it is forcibly controlled, failure is absolute, and forcibly controlling the spiritual power must be strong, so Feng Jin's fire control this time is a little hanging.

"Hey, this kid!" Yan Liefeng refiner for so many years could see at a glance that Feng Jin was not in the right state and was about to fail, but he also saw that Feng Jin was forcibly controlling and was about to succeed, Yan Liefeng, who had originally stood up and was ready to save people, sat down again, "The spiritual power is not weak!"

"Huhuhu~ finally under control. Feng Jin's face was pale, after all, a large amount of spiritual power output was not an easy job, so he couldn't stand it anymore. "Condensation, see how far I can go. Feng Jin knew that he would definitely fail, because the mental power consumption of the control link was too great to support the condensation needs, but he also had to try, the limit was broken like this, wasn't it?

"Stubborn boy!" Yan Liefeng shook his head with a smile, he looked at Feng Jin and seemed to remember himself who had learned refining weapons at the beginning of the year, and he was also so stubborn.

"How come?!" Feng Jin exclaimed, the spiritual power required for condensation was actually several times that of control, and the speed of sealing could not keep up, and he had failed just before he was about to try. Yan Liefeng extinguished the flames that wanted to explode with a wave of his hand, leaving Feng Jin, who was standing in front of the firewood pile stunned, and walked out alone, "Ahhhh

Feng Jin looked at the pyre and was distracted, replaying the scene of his previous fire control in his mind, over and over again. After the initial disbelief passed, he began to reflect on the refining weapon this time. "The speed of the control link should not be too fast, the mental power needs to be improved and strengthened, and the rhythm of fire control must be mastered. After replaying the scene just now countless times, Feng Jin summed up a few shortcomings, and also determined the goal of cultivation, in the final analysis, his spiritual power is still too weak, if there is enough spiritual power, what does it matter if he forcibly controls it?

"Senior Yan, do you have any way to improve your spiritual power?Is there a way to cultivate your spiritual power?" Feng Jin went to find Yan Liefeng after his spiritual power recovered, he didn't have much time left, so he had to speed up. "If you control the fire more, your spiritual power will naturally increase, and as for the method of cultivating your spiritual power, I don't have the ability to get it, and I can't get it. Feng Jin was very disappointed, it was too slow to improve by just controlling the fire.

"Have you finished reading "The Complete Book of Materials"?" Yan Liefeng changed the topic, that kind of trick is not realistic, this is very practical, "...... Not. Feng Jin was a little embarrassed, just like being caught by the teacher for not completing his homework, "But I have a question, some metal materials have the same effect as some herbs, so can the refining device add herbs?"
