Xu Dong entered the Lotus Cave and suddenly had inexhaustible wealth, but he was not worried.

In order to serve these herbs, Su Hong was busy enough and spent a lot of energy.

She went down to the pool several times a day, called bathing, and found a canine's tooth crystal from the bottom of the pool.

How dare Xu Dong practice these medicinal stones that have poured Su Hong's hard work into it, and it is not the same thing?

But this massive amount of medicinal stones, if they are not refined into pills and taken in the original way, they will not be able to break his stomach?

"Alchemy!"

"Su Hong, get the medicine!"

He gritted his teeth and gave Su Hong instructions.

Su Hong, this woman, can also be described as Lan Zhihuixin, she also has a very good set, and she recognizes all kinds of medicinal materials.

Which medicine has five leaves, which one has only four, which one has white flowers, and which flower is blue and white, she remembers ** not far from ten.

Now, when Xu Dong wants to extract these drugs, Su Hong is a living pharmacopoeia.

This made Xu Dong feel Su Hong's intelligence, agility and usefulness again.

"Su Hong, bring two purple gold flowers, twenty years. ”

With just one call, Su Hong immediately took the medicine to the fire room and asked Xu Dong to bake.

There are a few medicines that are so weird, the low vintage is easy to bake into a puree, the older one is a little higher and the old roast is not dry, these guys are soft and hard and don't eat it.

Xu Dong was really annoyed.

This matter was solved by Su Hong in one sentence.

"Shaoxia, isn't there an ice room next to the fire room, you put these medicines in the ice room to roast. ”

Put it in the ice room to bake? Su Hongmo's consciousness is not reversed.

But it doesn't hurt to give it a try, it's not too much work anyway.

Xu Dong tried it, and sure enough, the medicinal herbs were dry after a while after being placed in the ice room.

"Young man, the extremes of things must be opposed, fire is ice, ice is fire!"

This made Xu Dong understand a truth, sometimes, the material world is also upside down, fire is ice, and ice is fire.

Just as yin and yang are reversed, yin is yang and yang is yin.

Derived from this, the extreme yin is the extreme yang, and the extreme yang is also the extreme yin.

The fire that is synthesized from the fire of the extreme yin and the fire of the extreme yang is the "fire of yin and yang".

This particular "fire" is both ice and fire.

When it turns into ice, it can extinguish the fire, and when it turns into fire, it can melt the ice.

After more than 300 kinds of medicinal herbs were dried one by one, Xu Dong opened the second secret room and instructed Su Hong to bring in the dried medicinal herbs.

He cleaned the reproductive totem-like scooping pestle, put the herbs and spars into the stone yin basin, and then recited the spiritual trick to let the stone yang root return to its place automatically.

"Tom!

The yang root pounded the pestle in the yin basin, and the impact was so powerful that sometimes the medicinal juice splashed, and after a while, the medicinal stone was pounded into medicinal mud.

Su Hong looked at this scene, and two blushes flew on her face with shame.

Xu Dong asked Su Hong to give his hand, and he carefully put the medicine clay into the Ding furnace.

Su Hong said, "Shaoxia, you taught me how to make alchemy, right? I learned it, I will save you some snacks in the future!"

"Hmm! If you don't have the heat, the medicine mud will naturally become a pill, and if the heat is too much, it will burn to ashes. ”

This time, due to the large number of medicinal stones, the refining time was more than twice as long as the previous time, and a total of seven days and seven nights were consumed.

After seven days and seven nights, when the Ding furnace was opened, a strange fragrance came out.

In strict accordance with the requirements of the book, the Condensing Fire Pill made of more than 300 kinds of medicinal herbs and many canine tooth crystals was freshly baked.

The Fire Condensing Pill is a strong medicinal pill, and after a person swallows it, it will gather the fire attribute spirit element in the air and condense it into essence in the body.

This essence seed is conceived, and it continuously produces fire attribute spirit elements, and the cycle repeats itself until the spirit elements in the human body are full.

After the spirit element is full, it will be swallowed by the blood of the practitioner, and this process of bursting, devouring, and then filling and devouring again is called refining.

Xu Dong came out of the Linggu Gate, was robbed and killed by Fang Wei in the forest, was rescued by the red-line girl, and stayed in her cave for four days.

Back in the Lotus Cave, in fact, there are only sixty-seven days left before the day of the Linggu Gate martial arts competition.

It took seven days to refine the Fire Condensing Pill, and there were only sixty days left for pure cultivation of Yin and Yang Fire.

If you follow the normal procedure, it will take at least one year to practice Yin and Yang Huo, that is, 360 days.

If the cycle of 360 days is shortened to 60 days, then it is a pair of six, and you have to do six days of work a day.

Rushing to practice in such a hurry is something that an ordinary practitioner would not dare to think about.

But Xu Dong is not an ordinary person, he is a genius, and Su Hong, who is his partner, is also a genius.

However, genius is also limited by time, and cannot be like a wild horse that has escaped from the leash, galloping at will.

Therefore, Xu Dong now has to count the time to practice yin and yang fire.

The Yin and Yang Fire is divided into five stages, and the time he schedules for each stage cannot exceed twelve days at most.

Due to the previous lack of a solid foundation, even if the spiritual power was stored at the fastest speed, it took half a month.

These fifteen days are, of course, out of budget, and must be saved within budget.

The first stage of "Peiji" was successful, and it took only eight days.

Now it is the second stage, the "trial", which has taken ten days, and it seems that there is no light yet.

According to the book, if the trial is successful, the spirit will be vigorous, and the face will glow red, and the yang will not be able to disappear by itself.

And at this moment, it was still very silent, and the big handful of pills entered the stomach, as if it was digested as food.

"How is this possible? How can it not come?"

Regarding Xu Dong's anxiety, Su Hong could only keep comforting him with words and telling jokes to divert his attention.

You must know that if a practitioner is unstable and rushes too much, causing the yin and yang in the body to lose balance, he will go mad.

After the joke in Su Hong's stomach was finished, Xu Dong didn't laugh, but his attention was shifted to another place.

"Shaoxia, I've been searching my intestines and scraping my stomach for a long time, why are you so hard-hearted and don't laugh at all?"

In fact, it wasn't that Xu Dong didn't want to laugh, but that there was a change in his body, which attracted his attention.

"Su Hong, you use your divine sense to look aside to see if the air around you is shaking. ”

Following Xu Dong these days, Su Hong has also learned some small knowledge, the most intuitive is to observe things with divine sense.

"Shaoxia, it's shaking, and it's shaking more and more, look, look ......"

Xu Dong looked at Su Hong's fingers, and some red dust floated up and down, shining with stars.

He used internal vision to examine his body, just like a fire burning in the hearth, and the upper and lower dantian were even engulfed by the grand flames.

From the inside and out, Xu Dong's eight large chest muscles bulged out, and then the muscles all over his body bulged, as if he was about to break the skin.

What he could experience the most, of course, was the place, which also seemed to be on fire.

"Su Hong, it's burning, quick, help me put out the fire!"

He pulled Su Hong to do a good thing right now, Su Hong bounced away as if frightened, and laughed "giggle!" while dodging smartly.

"Shaoxia, don't, don't ......"

"Either way, now or not, you go into the ice room!"
