At this time, Xie Yukun called: "Lin Jun, hurry up and release all your divine sense, put all of your divine consciousness into the alchemy furnace, and pay close attention to the changes in that piece of dark iron." If the Xuantie gradually turns red, it means that the temperature of the earth fire is high, and the old man will cast a spell to beat the cold qi of the Xuan Ice into it, and the temperature of the earth fire will drop quickly. If the color of the dark iron turns white, it means that the temperature of the earth fire is not enough, you do the work of heating up the earth fire, you inject the crystal fire into it, your crystal fire has a leading effect on the earth fire, the crystal fire you release is vigorous, then the earth fire will also be very vigorous, if you control the crystal fire like a trickle, then, the earth fire will also become very gentle. You and I work closely together to ensure that the fire is always at the optimum temperature. Keep a close eye on that piece of black iron, as long as the black iron is cyan, it proves that the temperature of the earth fire is just right. ”

In front of the alchemy furnace, a wooden high platform was set up, which was about the same height as the Dan furnace that rose in the air, at this time, Lin Jun was sitting cross-legged on it, boosting his internal strength, and according to the "Divine Soul Formula" given to him by Xie Yukun, he released his divine consciousness and invested it in the Dan furnace, where Lin Jun was located, it was just against the Xuantie in the Dan furnace, so he could clearly probe the state of the Xuantie through his divine sense.

At this time, the dark iron was orange-red, and it seemed that the earth fire that had just steamed out was indeed very vigorous, I saw Xie Yukun and eight maids doing it together, and a white pillar of light hit the earth fire, and the flames that erupted were quickly suppressed, Lin Jun found that Xie Yukun's cultivation did not know what kind of exercises, which actually made Lin Jun feel a chill to the bone, as if he was sitting naked in the snow on a cold day, it was a kind of chill that enveloped everything from the inside out.

Soon, the earth fire was suppressed, and the dark iron in the alchemy furnace turned gray-white, and Lin Jun knew that the time had come for him to show his talents. Lin Jun's palm erupted a long flame, this flame is extremely peculiar, the core part, shining with red light, but around the flame, it is a golden light, this flame hit the bottom of the Dan furnace, the suppressed earth fire steamed up again, this time, the earth fire that encountered the crystal fire suddenly changed from an unruly wild horse to a docile little flower cat, with the rhythm of the crystal fire released by Lin Jun gushing outward, the crystal fire released by Lin Jun is larger, the earth fire will spurt more violently, the crystal fire is smaller, and the flame of the earth fire will also fall back a lot。

Lin Jun concentrated his divine sense on the piece of dark iron in the Dan furnace, carefully controlling the size of the crystal fire in his palm, after consuming the three crystals, the earth fire tended to stabilize, and the dark iron in the alchemy furnace remained cyan.

A few days ago, the spar that Xie Yukun gave to Lin Jun was specially used for Lin Jun to practice "Alchemy", and today, after the official start of alchemy, Xie Yukun will naturally have all the spars needed. In this way, Lin Jun does not have to worry about the consumption of spars, and can use his "Alchemy Technique" with all his strength to cooperate with Xie Yukun's alchemy.

Xie Yukun, who was suspended in the air, was very satisfied when he saw the scene in front of him, and nodded again and again with a smile. Before this, when Xie Yukun was refining the pill, he needed to consume a large amount of true qi in his body to control the size of the earth fire, and the power of the Xuantian Cold Ice Array formed by him and all the maids to control the earth fire was too powerful, and after the majestic Xuanbing cold qi was punched out, the potential energy of the earth fire would be pressed down at once. The previous time, it was because the cold qi of Xuan Bing completely suppressed the earth fire, causing the alchemy furnace that completely interrupted the energy of the earth fire to fall to the ground from the air all at once. Therefore, when they were alchemizing before, their control of the earth fire was far less than that of this time.

Lin Jun sat quietly on the wooden platform, paying close attention to the changes in the Xuantie, and after seeing that the Xuantie was stabilizing, Lin Jun, under the guidance of curiosity, quietly probed his divine sense into the depths of the alchemy furnace, but in the depths of this alchemy furnace, there seemed to be a huge spatial attribute.

The inside of the alchemy furnace was a large black press, as if it was a bottomless pit, no matter how long Lin Jun's divine sense probed inside, it was always pitch black, and nothing could be seen.

Xie Yukun found that Lin Jun was exploring the mysteries in the alchemy furnace, he roared loudly and reminded Lin Jun: "Lin Jun, you have to concentrate, don't get distracted, and always pay close attention to the changes in the Xuantie, when you are alchemizing, the Xuantie is not changing slowly, but it may change from white to red in the blink of an eye, so you must not be negligent." ”

This is since Lin Jun met Xie Yukun, Xie Yukun spoke to Lin Jun in the most severe tone, which shows how much Xie Yukun attaches importance to the matter of alchemy.

Lin Jun didn't dare to think about it anymore, and quickly withdrew his divine sense, staring at the piece of dark iron, the only thing he could see in the alchemy furnace.

Xie Yukun, who was floating in the air, had a big sleeve, and his body emitted colorful light, and then, these rays of light turned into countless pillars of light, flying towards the base of the alchemy furnace, hovering continuously around the base, converging into a colorful circle of light, and this circle of light dragged the alchemy furnace upwards by a zhang.

Then, Xie Yukun said to Lin Jun: "Increase the earth fire and increase it to the maximum." ”

Lin Jun pushed forward with both palms, and two flames erupted from his left and right palms, and two incomparably pure crystal fires hit the earth fire, and the earth fire immediately increased in flames, and the eight flames that erupted out were like eight fire dragons poking out from the ground, projecting a more fiery breath. However, under the protection of the ring formation formed by the eight maids, the blazing hot aura emitted by the earth fire that erupted from under the alchemy furnace was always firmly controlled within the formation, and it did not increase the temperature in the entire alchemy room much.

Lin Jun felt that the formation composed of these maids must be a relatively high-grade water attribute formation, and this formation exuded a chill, which could resist the heat wave that erupted.

"Lin Jun, it's okay, take it!" Xie Yukun, who was floating in the air, reminded Lin Jun.

Lin Jun focused his attention and took a closer look, and sure enough, the piece of dark iron hanging in the alchemy furnace suddenly turned red, and it became more and more red. Lin Jun immediately withdrew his hand, recovering the power in his hand, and the two fire dragons that erupted from his hands turned into two subtle flames, losing the support of the crystal fire, and the vigorous and vigorous earth fire eruption suddenly decreased a lot.

After the temperature dropped, the color of the piece of dark iron in the alchemy furnace gradually faded, and slowly, it turned cyan again, indicating that the temperature in the alchemy furnace was normal.

Before starting this alchemy, Xie Yukun gave Lin Jun and each of the female disciples a high-grade Bigu Pill, this elixir can make the monk not eat or drink for ten days, and still maintain strong physical strength, it is a high-grade and excellent elixir.

After taking this elixir, Lin Jun knew that Xie Yukun, an old man, turned out to be a workaholic, and it was an extremely hard and devastating job to accompany him to refine the pill. Because since the day the earth fire began, Xie Yukun actually led everyone to refine the mysterious thing in the Dan furnace day and night without closing their eyes for ten days and ten nights.

On the tenth day, the fire began to grow and become unstable. Xie Yukun asked Lin Jun to retract his hand, took back all the crystal fire, and then released the powerful Xuanbing cold qi again, and the cold qi brought endless frost, all the way to shrink the earth fire into the stone cave.

Then, Xie Yukun once again played a multicolored aura, which dragged the alchemy furnace down steadily and landed on the stone platform.

Then, the maids rearranged the formation again, and with Xie Yukun's cooperation, the huge stone platform under the alchemy furnace rotated back again, covering the eight huge stone caves.

Xie Yukun took out several talismans from his sleeve and threw them out, all of which flew to the stone platform accurately, and soon merged into the stone platform, and the entire stone platform emitted a burst of white cold light, and then returned to normal.

Xie Yukun, who had been suspended in the air for ten days and ten nights, was full of exhaustion, and the eight maids fell staggered on the futon under them one by one, and they had no strength to consume.

Xie Yukun came to Lin Jun's side, and said with a smile: "Lin Jun, the old man has practiced the elixir all his life, and only this time he is the most handy and the most comfortable. This time the refining was extremely successful, and if it continues like this, if it is practiced for another two or three years, the old man will definitely be able to achieve great success. Lin Jun, you have made a great contribution this time, what reward do you want?"

Lin Jun fell on the wooden platform with a thud and said, "I don't want any reward except for a beautiful sleep and a full meal." ”

"Ha, ha, ha, ha!" Xie Yukun's hearty laughter resounded throughout the alchemy hall.
