Wei Kang already looked like a fairy with immortal wind bones, and his face was serious at this time, and he was full of a sense of majesty, coupled with the huge spiritual pressure surging on his body as a monk in the late stage of foundation building, which made people dare not face it.

It seems that he attaches great importance to the alchemy of this furnace, and he also took the trouble to explain it to Shen Tong, without the slightest impatience, just listening to him say slowly: "The refining of the pill is actually no different from the cultivation of the monk, the lower the quality of the pill, the smaller the spiritual power required, the lower the quality requirements for the material, and the higher the success rate." With the improvement of the quality of the elixir, the higher the requirements for the year of the spiritual materials, the more the requirements for the quantity of spiritual materials, and the success rate will be the opposite, which will be lower and lower. ”

Shen Tong just listened carefully, not daring to be careless, for fear that when the time came, he would ruin the good deeds of this cheap master and cause great trouble.

Wei Kang looked at Shen Tong's appearance, and couldn't help but nod with satisfaction: "This time the furnace is alchemy, and the pill refined is called 'Burning Spirit Pill', which is based on the old man's spiritual root attributes, and is used to match the Ning Dan, and its main ingredient is thirty-five kinds of fire attribute spirit grass, each of which requires more than 5,000 years of medicinal age, as for the ingredients, it is mainly based on the blood of five fire attribute demon beasts, and then combined with some other spiritual materials to condense into Dan, so the entire alchemy process is divided into two parts, one is refining materials, and the other is Cheng Dan. Because this pill is all fire attribute spiritual materials, the so-called rigidity is extremely easy to break, so it is necessary to add water spiritual power to it when refining materials to alleviate its medicinal properties, so as to ensure that when it becomes a pill, it will not explode because the fire spiritual power is too strong. ”

Shen Tong frowned and asked, "Master, how do you infuse water spiritual power into it?"

Wei Kang nodded, stretched out his finger and pointed to the position opposite Shi Chang, and then said: "You only need to sit there and run the exercises to absorb the spiritual power of heaven and earth, and I will control the Huoyun Furnace to draw spiritual power from your body at the right time, but this time refining the elixir, because there are too many spiritual materials, it will last for a long time, so you need to ensure that the spiritual power in your body is sufficient." After finishing speaking, his mind moved, and immediately four medium-grade spirit stones appeared in front of Shen Tong, and the aura was compelling. However, because of the astonishing exuberance of the fire spiritual power here, the dissipation speed of the spiritual power of those few spirit stones was greatly accelerated.

"You put away these spirit stones first, in case you need them, remember, once the spiritual power in your body is exhausted, you must quickly replenish it through the spirit stones, and you must not spoil the alchemy event. Wei Kang couldn't help but look serious as he spoke.

Shen Tong put away the spirit stone with a move when he heard this, then nodded seriously, and sat down at the place where Wei Kang stretched out his hand according to Shi Chang's previous appearance, and then slowly started to exercise. It's just that the fire spiritual power is too strong and domineering at this moment, and the water spiritual power that can be drawn from the void is really pitiful.

However, according to what Wei Kang said, Shen Tongxin's worries couldn't help but be much less, he didn't need to instill spiritual power into the furnace, he didn't need him to control the timing, naturally the pressure he took on was much less, which was a relatively reliable arrangement for Shen Tong, who participated in this kind of alchemy for the first time, otherwise he was really afraid that something would go wrong.

Seeing that the two of them were already in place, Wei Kang nodded with satisfaction, and then he slowly walked to the edge of the stove and glanced at the stove with a complicated expression.

After a while, he waved his hand at the huge stove in front of him and played a trick, and the stove, which had been standing quietly, suddenly made a sound, and the inscription on the stove instantly shone brightly, dazzling.

Shen Tong, who was sitting there cross-legged, couldn't help but be startled by the movement in front of him, and couldn't help but look there with wide eyes, the amazing change of the stove also made him frightened for a while. At this moment, Wei Kang shouted: "Hold on to your mind and run the exercises!"

Shen Tong was shocked by this shout, and immediately didn't dare to look at it anymore, closed his eyes again and silently started the exercises, but the whistling sound in his ears made it a little difficult for him to calm down after all, and the astonishing changes and dazzling appearance of the furnace just now kept appearing in his mind. At this moment, he felt a wave of heat rushing towards him, and although he had the Fire Bead to protect his body, he still felt all over his body, so he could imagine how amazing the temperature in the secret room was at this moment. However, with the previous lesson, he didn't dare to move anymore, and he didn't even dare to open his eyes, just silently running the exercises. Reading.com

On the opposite side of Shen Tong, Shi Chang, who was obscured by the stove, waved his hand to play a magic trick at this moment, and then saw that with the operation of the magic trick, the fire under the furnace was in vain. The flames suddenly rose up, enveloping the entire furnace in one fell swoop, and the sound was extremely amazing.

The secret room here was originally built in the belly of the mountain, and was built on the fire of the leylines. In fact, the entire Shaking Light Peak's several courtyards are like this, borrowing the power of earth and fire to refine the elixir, and the secret room for its alchemy is naturally built on the fire vein. Originally, when it was not in use, the fire vein was banned, but now once the ban is lifted, its leyline surges, and its power is naturally spectacular and amazing.

However, Wei Kang and Shi Chang are naturally very familiar with this, and there is no panic at all in front of them, Shi Chang is trying to control the fire veins on this side, and Wei Kang on the other side has already waved his hand to play a trick, and then the furnace lid flew up, and a red light shining spirit grass was thrown into the furnace fire. At the same time as the lid was lowered, the fire under the bottom was full for a while, and the temperature in the entire secret room was amazing.

The three of them sat down separately in this situation, only the raging flames were constantly rising, constantly devouring the spirit grass. However, this spiritual herb is originally full of fire spiritual power, and after encountering the flames, the fire shines more and more, and it appears extremely agile, and even its body begins to change under the nourishment of fire spiritual power, as if it has an independent divine consciousness and wants to escape from this furnace.

It's just that no matter how the spirit grass changes and how it impacts, it is always fixed in that furnace, and with the continuous influx of the leylines, its body becomes more and more illusory.

After three full days like this, the spirit grass seemed to have finally been broken by the fire spiritual power, and began to gradually dissolve into a mass of liquid, but even so, this mass of liquid was still constantly moving, full of spirituality. Until this time, Wei Kang, who originally had a serious expression on his face, finally showed a hint of joy.

A few hours later, when the mass of spiritual fluid finally stopped changing, the magic formula in Wei Kang's hand changed, and a suction force immediately came from the furnace. Shen Tong, who was sitting there immediately, suddenly shook his body, and felt that the spiritual power in the sea of qi had disappeared a lot in vain, which made his face suddenly ugly.

And after the spiritual power in his body full of water spiritual power poured into the furnace, it suddenly turned into a crystal jade net, and instantly wrapped the spiritual liquid in it, and then as soon as the furnace lid was opened, Wei Kang skillfully took out a spiritual bottle and filled the spiritual liquid into it, and the whole action was completed in one go, without the slightest delay.

After spending so much energy and time, this spiritual material was finally successfully refined into a ball of spiritual liquid, looked at Shi Chang, whose expression was becoming more and more full, and then looked at Li Ping, whose face was a little ugly, Wei Kang groaned for a while, and took out another spiritual material without the slightest pause. It was a antler-like branch, and its fiery red body shone with a blinding red light, and it was vaguely as if a red light could be seen circling in it. And as it came into contact with the fire spiritual power in the air, the antler-like branches of the tree immediately began to grow larger and thicker, as if it was constantly absorbing the fire spiritual power to strengthen itself.

At the same time, Shi Chang's face did not move, but the magic trick in his hand changed, and the flames at the bottom of the furnace suddenly became a little stronger.

Seeing this, Wei Kang waved his wrist, and the growing branch was immediately thrown into the furnace, and with the lid of the furnace, the whole furnace roared for a while, and it seemed that with the growth of the branch, it was constantly impacting the furnace wall. However, I don't know what kind of material this furnace is made of, and its strength is far beyond imagination, but I heard the roar getting louder and louder, but the furnace is still and has not changed in the slightest.

Seeing this scene, Shi Chang's expression remained unchanged, and he couldn't help but continue to destroy the magic technique, making the fire of the leylines bigger and bigger, and the temperature in the secret room getting higher and higher. Soon, the entire chamber seemed to become a sea of fire, and the fire dragon flew with great momentum.
