Calculating that the time was almost up, Li Yunxiao simply packed up and left the black land again. However, when he came to the exit of the Black Mist Zone, his face darkened when he saw Sun Zhongtian leading the four cultivators sitting there cross-legged.

It is impossible to rush out, it is an act of looking for death, Sun Zhongtian only needs one palm to seriously injure him. Flying away from the sky will not work, because the spiritual power of a martial artist is limited, and there will always be a time when it is exhausted, and Li Yunxiao's spiritual power is even more unbearable.

There was no way, Li Yunxiao had no choice but to continue to return to the black land to stay honestly, and officially start to practice refining beast blood, anyway, staying is not staying, he has to find something to do.

Refining the blood of the Demon Beast is the most basic step in refining the Battle Qi Talisman, it is not difficult to say, it is not easy to say that it is not easy, the key point is the control of firepower. Each type of demonic beast, even a demonic beast of the same level, has a different amount of energy contained in its blood, so the firepower required is also different.

On the contrary, if it contains less energy, the demand for firepower will be lower, otherwise the firepower will destroy the blood components.

Therefore, whether or not you can successfully refine a beast blood depends on how well you control the firepower. And if you want to accurately control the firepower, whether it is for the soul or the spiritual power, it is an extremely strict test.

Everything is ready to go. Li Yunxiao sat cross-legged, held his breath and concentrated, and after he was calm, he took out a piece of the beast blood of the green wolf from the ring, poured it all into the blood refining tripod in front of him, and then moved his heart, and with a little finger, a flame came out from the bottom of the blood refining tripod. This is naturally the battle spirit released by Li Yunxiao.

Under the barbecue of the flame, the blood refining tripod quickly turned red, and the temperature of the blood in the tripod gradually increased, and it began to move.

"The firepower could have been a little harder. Hearing Juechen's guidance, Li Yunxiao slowly increased the output of spiritual power, and the flames at the bottom of the blood refining peak also became larger.

When the flames reached the size of an adult's fist, Jiechen spoke again: "Okay, that's it. In the future, when this kind of blood is refined, it will be heated according to this firepower. Of course, after you are thoroughly familiar with the nature of the green wolf beast's blood, you can also combine your own strength to determine the strength of the firepower. The most important point is to maintain the stability of the temperature, and avoid high and low levels. ”

"Got it, teacher. ”

Li Yunxiao responded, his eyes staring closely at the beast blood in the Blood Refining Ding, observing its movements. After this kind of roasting lasted for a while, the beast blood in the ding finally boiled.

"Be careful, now is the critical time for refining, you must maintain a high degree of attention, and use your soul to detect the impurities and essence in the blood of the green wolf, and then increase the temperature of the flame little by little, until this temperature can destroy the useless impurities in the blood, and it will not hurt the essence in the blood before stopping. ”

While staring at the Blood Refining Ding, Jiechen told Li Yunxiao about the places that needed attention, and then his words had just fallen, and a pungent smell came from the Blood Refining Ding, and the blood of the green wolf beast was black in color, and it was already a mess. Fun reading little books

Li Yunxiao had seen the blood of the Absolute Dust improve before, and felt that refining the blood of the beast was a very simple thing, not just to put the blood refining tripod on the ground, raise a flame at the bottom of the tripod, and then put the beast blood into the tripod to bake, and wait until the blood rolled over, then turn off the fire, and it could be completed in two or three minutes before and after, but I didn't expect that when it was my turn to go into battle, not only did it take so long, but it was also baked in the end.

Looking at the black mass in the ding, Li Yunxiao recalled the process of refining the beast's blood just now, thinking that he had been extremely careful, and all the procedures were also done according to the teacher's prompts.

Jiechen's expression was calm, and he didn't interrupt Li Yunxiao's thinking, until Li Yunxiao's face was suspicious, and he looked very puzzled, before he spoke: "You did a good job just now, and the reason why you failed is because you are not familiar enough with the ability to control the flames, which leads to too high temperature." ”

"Really?" Li Yunxiao didn't believe the teacher's words, but he really couldn't figure it out, because he felt that he had a good control over the flames, and the temperature was also raised little by little, so it shouldn't be possible to cause the temperature to be too high.

"I know you're struggling with something. Jiechen smiled and said, "One thousand degrees is a critical point for destroying the impurities in the blood of the green wolf, and one thousand and fifty degrees is another critical point for destroying the blood essence of the green wolf beast, then the temperature of the flame that you controlled just now can only stay between these two critical points." If it is too low, it will not destroy the impurities in the blood, and if it is too high, it will destroy the blood essence. Do you still think you've done that?"

"There is only a fifty degree difference between the two critical points? How to grasp this, a little distraction, or a slight tremor of mental power, or interference by other external factors, etc., may cause temperature instability. ”

"Yes, all of this requires the alchemist to have an absolute grasp of the temperature of the flames, and no deviations are allowed. The green wolf is only a first-order demonic beast, and the critical point difference of blood is quite large, and the critical point difference of blood of those high-level demonic beasts is exaggeratedly small, even four or five degrees. ”

"Four or five degrees, no, how can this be controlled?" Li Yunxiao's mouth opened wide, and he seemed to be frightened by Jiechen's words.

"Otherwise, do you think it's so easy to be a Battle Qi Talisman Refiner?" Jiechen's tone changed, and he squinted at Li Yunxiao and said, "But for you, it's not a problem. What you lack now is only experience and proficiency, so what you have to do now is to practice a lot, boy, work hard, practice a lot, only after a lot of tempering, the foundation is solid little by little, it is possible to become an excellent talisman refiner. ”

"Got it. ”

Li Yunxiao felt a lot of pressure, but he no longer had the decadent state he had before, his face was resolute, and his eyes were full of confidence, as if to say, I can do it, I must be able After adjusting his breath, he poured the waste blood in the blood refining tripod, poured a bottle of green wolf's blood again, and began the second refinement.

Not long after, a scorching smell wafted from the Blood Refining Ding again. Obviously, he failed again this time, and again in the same place. Although he had been careful enough to raise the temperature little by little, he still did not control the temperature of the flames.

Make persistent efforts, pour out the waste blood, start again, and after more than twenty minutes, the blood in the blood refining tripod has become a black "mud" again. Li Yunxiao's expression remained unchanged, and he poured new beast blood again.

Refining this kind of talisman foundation is a very boring thing, and then Li Yunxiaoju was full of interest, and he couldn't help it, and he refined it thirty-five times in one breath, until his face was pale, his physical strength was weak, and his spiritual power was exhausted. He let out a long breath, not expecting that refining blood would be such a tiring task.
