There are two necessary conditions for the growth of Danlu embryos.

One is to absorb the fire, the more the better, start to absorb from the lowest level of fire, before absorbing the low-level fire of sufficient level, if the high-level fire is absorbed, it will be irreversible, just like laying the foundation.

The second is to use the Dan furnace to refine medicine, the more pills refined, the more familiar the Dan furnace is with the medicinal properties of various elixirs, which is different from fire, not limited by the level of refining pills, but the opportunity to refine low-grade pills after the cultivator is advanced is bound to be very few, and at that time, if it is specially for the Dan furnace to make up for the medicinal properties of low-grade herbs, it is undoubtedly a waste of time.

But now it is undoubtedly the most suitable for Yang Yifeng, who has just refined the body realm.

He and the Dan Furnace embryo can grow in tandem, can make the best use of time, and can also start refining into the Dan Furnace from the lowest level of fire.

"Duh!"

Yang Yifeng snorted lightly.

An arcane rune struck the Dan furnace.

The entire Dan furnace "hummed" for a while, and the Dan furnace lid was uncovered by itself, slowly levitating above the Dan furnace.

The old medicine that had been prepared and cultivated with the Aoki Regeneration Recipe was already neatly placed on one side.

The years of each old medicine are more than 100 years, and even 200 years!

You must know that when I got it from Chu Yanran, the oldest medicine was just in the early 100s, and it had only been less than two months since then, and it had accelerated its growth for more than a hundred years!

Moreover, if an alchemist who is familiar with medicinal herbs sees it, it is easy to find that the elixir catalyzed by the Aoki Regeneration Recipe is much stronger than ordinary old medicines, whether it is the purity, quantity, or medicinal properties that contain the aura of heaven and earth.

There is no need to worry about the harm of pulling seedlings and fueling them.

"Mom, ten plants of He Shou Wu!"

"Ten Snow Lotus!"

"Nebula Grass Eight ......"

Every time Yang Yifeng shouted the name of a medicinal herb, Fan Bing, who took the initiative to give his son a hand, would quickly throw the medicinal herb that Yang Yifeng wanted into the Dan furnace.

The temperature of the furnace, the time of delivery, the timing of the purification and fusion of the herbs in the Dan furnace, etc.,

Yang Yifeng has been controlled to the pinnacle of wonder.

Although he didn't have any fire at the moment, and he only relied on burning true yuan, refining this lowest-grade pill was enough.

In the blink of an eye, three days have passed.

The entire garden of the villa was almost depleted of medicinal herbs.

Only one of each herb remains, which is cultivated as a seed.

This kind of elixir, old medicine, it takes a long time to cultivate seeds, not to mention, and it requires specific conditions to be successfully cultivated, which is difficult for Yang Yifeng.

It just takes time.

Otherwise, as long as the elixir provided by Chu Lao does not need to be collected, only the elixir that is not available can be collected, and each elixir only needs one plant, the quantity does not matter, it can be cultivated and reproduced, and it can be produced in large quantities.

At this moment, a large amount of pills were piled up in Yang Yifeng's storage bag.

Most of them are Xiao Pei Yuan Dan.

And each one has a clear dragon pattern phantom circulation, and it is the best one-turn elixir!

Moreover, the aura of heaven and earth contained in this superb Xiaopei Yuan Dan is more than 100 times that of Yang Yifeng's improved version of Baicao Dan, that is, Baixiang Dan!

Even in the Jiuxuan Continent, where Xiao Pei Yuan Dan is popular, the dragon pattern superb Xiao Pei Yuan Dan is not something that ordinary cultivators can afford, and in the earth where heaven and earth are lacking in spiritual energy, it is even more rare.

In addition to Xiao Pei Yuandan,

There are also some pills that contain special medicinal properties.

Yang Yifeng also used it as an ordinary elixir to neutralize the medicinal properties and refined it into a pure energy pill.

Although it's a pity to waste medicinal properties,

But what he needs now is the aura of heaven and earth.

It is necessary to prepare as much as possible in order to be able to complete the higher foundations.

If it weren't for the trip to Fuxian Lake, Yang Yifeng might not have taken it so seriously, after all, in the earth of the end of the law era, it was not realistic to want to impact a higher level of foundation building.

But with the source of the spiritual veins of Fuxian Lake, Yang Yifeng has the hope of impacting the earth's veins to build a foundation.

It becomes quite necessary to prepare as many elixirs as possible!

"Mom, before I come back, you stay at home, don't let anyone enter the villa, if someone trespasses, directly order, let Xiaobai start the killing array!"

"Well, Xiaofeng, you don't have to worry about your mother, but you, are you really sure?Building a foundation is not a child's play, success comes naturally, and going with the flow is the right way, not long after you were promoted to the ninth layer of the refining body, will there be any danger in forcibly building a foundation?"

"Mom, don't worry. Before the college entrance examination, when I returned, I would be a master of the foundation building realm! Okay, it's been three days, Mom, you can rest and recover, I'll go first!"

After Yang Yifeng finished speaking, he waved his hand directly to his mother and stepped out of the villa.

There is no need to hide it from his mother, Yang Yifeng has already told his mother.

Just to reassure my mother, what he said was relatively simple.

In fact, as his mother said, building a foundation, even for him, the former generation of immortal kings, is a very important thing, although it is a recultivation, but whether it is the cultivation of the exercises, or the state of mind, it is no longer comparable to him.

Therefore, what will happen to him this time is not something he can predict.

All he can control is the general direction.

The secret of immortality is the strongest practice of refining the body.

Aoki regeneration is also the top technique.

The two complement each other, even on the earth of the end of the Dharma era, Yang Yifeng can clearly feel that his cultivation of returning to his true self has far surpassed him in the Nine Xuan Continent on the foundation.

......

The sun is shining.

After refining medicine for three days and three nights, Yang Yifeng was still in good spirits.

Essence, energy, spirit, true element, qi and blood, in the process of refining medicine, you can achieve a balance of consumption and absorption.

With his mind released, Yang Yifeng squinted his eyes and glanced at the roof of the villa not far away.

The figure flickered, and the speed increased suddenly.

A moment later, he quietly reached the roof of the villa.

The first thing that catches your eye is two snow-white long legs and pouting hips/parts.

Yu Taiying looked at the telescope, looking at the direction of the King of Time Junshu Building, and was observing.

didn't notice Yang Yifeng's arrival at all.

Yang Yifeng touched his nose and looked at the gently writhing back in front of him with interest.

Looks like a lot of ecstasy/soul......

"Ahem. ”

"Who?"

After Yang Yifeng watched for a long time, and Taiying watched motionlessly, without the slightest sign of stopping, Yang Yifeng coughed lightly to remind, and Taiying suddenly turned around and slid down, moving as fast as lightning.

"Little brother, I'm scared to death!"

Seeing Yang Yifeng with a wicked smile on his face, Taiying looked shocked with a hint of surprise, and immediately gave up her vigilance and came to Yang Yifeng's side.

"Sister, your vigilance is not good, you can't sense it after I've been here for a long time, if it's an enemy, wouldn't it be bad? I haven't shielded my breath much......"

Yang Yifeng said.
