The furnace fire showed a dark blue color, emitting a halo, and it also illuminated the room in the dark night, and if people watched outside Li Ling's room, they would see a green shadow inside.

In the green shadow, it was Li Ling sitting upright in front of the Dan Furnace, and his palm was constantly sending Dao Qi into the Dan Furnace to maintain the continuation of the fire spirit.

Indoors, Li Ling's forehead has oozed sweat, most of his clothes are soaked with sweat, because the temperature in the furnace is too high, the temperature around the stove has also increased a lot, in Li Ling's room, there are a lot of wooden furniture, all of which have been scorched, although they have not ignited, but they have also been smoked enough.

"It seems that the next time you refine the pill, you can't refine it at home, this green fire is too hot, add a little bit of Dao Qi, the temperature around it will double, fortunately, this time the refining pill is just to try it first, otherwise, it's strange if this house is not on fire." Li Ling sighed secretly in his heart, the fluctuating air around him was the best reflection of the heat.

With the gradual condensation of the gas in the Dan plate in the Dan furnace, the color of the gas began to gradually change, this Dan Qi is the result of Li Ling's configuration of the Dan Pill after gasification, which has three auxiliary medicinal materials, plus a main medicine, the auxiliary medicine is: agave, disguis, dragon beard, the main medicine is the dragon silk.

Because the agave itself is a positive herb, after encountering the green fire, it will be the first to vaporize, and then it will become a neutral herb and a dragon beard, and the last is the dragon silk.

And Li Ling's purpose is to decompose these vaporized medicinal materials into molecules under the action of high temperature and green fire, and then recombine them from the molecules. It becomes a pill that combines the effects of four medicinal herbs.

Fusion is not an easy thing, Li Ling is also the first time to use green fire gasification medicinal materials to fuse, before Li Ling used red fire to liquefy medicinal materials to fuse.

Therefore. Liquefied medicinal materials, fusing medicinal material molecules, is not as good as gasifying medicinal materials, coming to perfection and harmony.

Looking at the medicinal herbs that were originally divided into several colors in a vaporized state, and gradually began to merge into one color, Li Ling said. Hope is slowly opening, that is the beginning of integration, and a good beginning is about to be born.

Even so. Li Ling can't relax, but needs to increase his strength, and the control of the heat must reach the point of perfection and perfection. Not a single detail can be missed. In these nine days, Li Ling's mental power can be said to be highly concentrated, and he completely ignores the interference of the outside world, if at this moment, someone wants to come in and assassinate Li Ling, it can be said that it is extremely simple.

"Agave and weed, one of these two is a fiery red molecule. One is a green molecule, which is easy to fuse. It doesn't take much time, after fusion, it will also turn gray color, but it is very difficult to fuse the good agave and disbeania with the dragon's beard, and the rejection of the dragon's beard is particularly strong, and it is difficult to integrate ordinary herbs into it. Li Ling observed carefully in front of him and analyzed.

As one of the divine beasts, the dragon's beard has the aura of the divine beast, and it is difficult to fuse it with ordinary herbs, but it is not impossible, Li Ling can be said to have exhausted the strength of the Nine Dragons and the Two Tigers to win a glimmer of opportunity for the fusion of the dragon's beard, agave and disguises.

The state of the dragon's beard after gasification is golden, and when the golden gas gradually approaches the gray gas, there is a strong rejection, but after each rejection, there will be a slight change, and the dragon's beard gas in the golden state gradually changes a little bit into a brownish-gold reaction.

"There's a chance." Li Ling was overjoyed in his heart, so he stepped up the fusion.

After the golden gas collided strongly with the gray gas several times, there was a violent repulsion between them, and then there was a little bit of fusion.

As long as it can be fused, the rest is a matter of time, Li Ling Zhilu said, if you want to successfully refine this elixir, you must spend time, the originally budgeted time of nine days, at this moment, it is estimated that it is far from enough.

"No, I'm too anxious, I have to slow down, otherwise the rejection of the dragon's beard gas will become more and more intense." Li Ling adjusted the strength of the Dao Qi in the palm of his hand, and lowered the temperature of the green fire by a few centimeters slightly.

I don't know how much time has passed, the gold and gray have finally fused successfully, and they all became brownish and gold-colored gas, Li Ling exhaled slightly, but then there was a more tense atmosphere.

"Oops, the combined medicinal herbs of the three kinds of medicinal materials and the final dragon silk actually produced such a powerful rejection." Li Ling looked at the Danpan that was constantly vibrating violently, and was very worried about this Danpan, worried that this Danpan would suddenly be overwhelmed by the force that was repelled inside.

In order to prevent the Dan Pan from being exploded, Li Ling tried his best to reduce the temperature of the green fire, and almost used a simmer to refine the Dan, even so, there were already cracks on the Dan Pan, looking at the Dan Pan that did not break, Li Ling's whole heart was going to jump to his throat, once the Dan Pan burst, the powerful impact force generated would constantly blow up the Dan Furnace, and even he would be seriously injured.

"No, it doesn't fuse, it's bad now. The most important thing is that the quality of the Danpan itself is too poor to withstand the mutual repulsion force of the gases. It seems that in the future, it is necessary to get some high-grade ores to cast a few Danpan with qualified hardness. Li Ling's heart flashed with thoughts, and he conveyed Dao Qi more carefully, and heated it with the lowest simmer.

Perhaps because of time, after a long time of simmering and refining, the gas finally no longer rejected, and the dragon silk that was originally a white gas, fused together, in short, the original gases of various colors, at this moment, are fused into a color of gas, brown gold.

With the success of gas fusion, Li Ling has to start to cool down, cooling down is also a delicate job, if it falls too fast, the Danpan will suddenly burst because of the temperature difference, so that the gas will collapse and fail.

Therefore, when Li Ling cooled down, he didn't dare to relax a little, and it would take at least a day and a night to cool down from the high temperature of tens of thousands of degrees.

As the temperature gradually decreased, those brown-gold gases began to turn into brown-gold dew drops that stained the surface of the Danpan, gradually flowing into the central hole of the Danpan, and polymerized to become a small puddle of medicinal liquid.

However, at this time, the temperature of the green fire is still more than 1,000 degrees, and at the last stage, it is to drop this more than 1,000 degrees until the green fire is extinguished.

The green flame was extinguished in the Dan furnace at once, and the medicinal liquid instantly solidified into a brown-gold solid pill, Li Ling slowly put down his hard arm, touched the beads of sweat on his forehead, and let out a breath lightly, and said secretly: "It's finally a successful condensation, damn, I'm about to die of exhaustion, and I'm about to collapse." ”

However, no matter how tired it is, it is worth it, the pill has finally been successfully refined, Li Ling opened the door of the furnace, took out the pill plate inside, unveiled the pill plate, and suddenly a refreshing medicinal fragrance overflowed, and suddenly the room was illuminated by the golden light emitted by the brown-gold pill, Li Ling knew how to look at the grade of the pill, and at a glance, the grade of this pill turned out to be the lower grade of the Tiandan.

It was completely beyond Li Ling's expectations, Li Ling actually refined a low-grade Heavenly Pill, and the spiritual cultivation that taught Li Ling alchemy back then had only refined a low-grade Heavenly Pill with the help of Feng Yu, but he didn't expect that this time Li Ling would also reach this alchemy level.

"Great, it's actually a Heavenly Pill, if it weren't for the Dan Plate not being strong enough, if you work hard, maybe you can refine a medium-grade Heavenly Pill?" Li Lingha smiled and held the medicinal fragrant Heavenly Pill, and his heart was extremely happy.

In fact, no matter how good the quality of Li Ling's Dan Pan is, it is impossible to refine a medium-grade Tiandan, not that Li Ling's alchemy skills are not enough, but because those medicinal materials in Li Ling's hands have been capped if they refine a low-grade Tiandan. Even if the quality of the Danpan is better and the green fire is stronger, at most, it is just to refine a better low-grade Tiandan, and the effect is only slightly stronger.

Li Ling took the lower grade Heavenly Pill in his hand and carefully put it into the space magic weapon, the value of this lower grade Heavenly Pill is not a matter that millions of ink crystals can buy, this is a lower grade Bone Pill that can directly improve the muscles and bones of one level.

Li Ling took a deep breath of satisfaction, got up and opened the door, just outside when the sun was setting, Hei Lin and Erwa were frolicking in the yard, looking at Li Ling who came out, Hei Lin pulled Erwa and said, "Your eldest brother Li Ling is finally out of the customs." ”

Looking at Hei Lin and Erwa who walked towards him, Li Ling was very happy.

"Hey, Li Ling, it's two months for you to go into retreat." Hei Lin said depressedly.

"What...... Two months have passed since I went in, so what happened outside? Li Ling couldn't close his mouth in surprise, originally it was only refined for nine days, but later, because of the relationship that could not be fused, Li Ling felt that it would be extended, but what he didn't expect was that it would be extended for more than a month.

"Of course a lot of things have happened, do you know that the Heavenly Thunder Regiment has come to invite you five times, but unfortunately I have rejected them, and now, the Heavenly Thunder Regiment is estimated to be regarded as the No. 1 enemy." Hei Lin said with a wry smile. (To be continued......)
