The Snow Rumor senior walked into the wooden house, and the place returned to its original tranquility again.

"One percent, top alchemists only have a one percent success rate, how is this possible?" Chu Cheng shook his head, not quite convinced.

If it was really that difficult, how could those great powers in ancient times snatch a heart flower and break the blood flow for the sake of their descendants?

Chu Cheng sat down cross-legged and took out a Dan furnace from the storage ring. This Dan furnace is ink-colored and lacquered, carved with a vermilion bird icon, a fiery red flame pattern, as if it is really about to erupt a fire.

This is the Dan furnace used by Changsun Tang during his lifetime, and its quality is naturally extraordinary, it is a three-grade Dan furnace.

The Sanpin Dan Furnace is as rare as a third-level alchemist in Qingzhou, but there are only a few dozen.

When Changsun Tang was killed by Chu Cheng, his things were naturally swept away by Chu Cheng in a swarm. However, what made people speechless was that Changsun Tang did not have many spirit stones on his body, and there were only more than 3,000 high-grade spirit stones.

Fortunately, there are many spiritual herbs and pills, and there is no shortage of pills used in the foundation building period. The Lian Ling Scatter used in the early stage of foundation building, and the Gathering Spirit Pill used in the middle and late stages are all complete, and it is not a small amount. Add up to at least five hundred.

This is simply a one-stop service, and the whole process is ready for Chu Cheng. Just waiting for him to step into the foundation.

Blessings and misfortunes are mutually exclusive, this sentence is not unreasonable, often in the midst of a crisis, there will be a creation.

Chu Cheng took a deep breath, took out a Lianxin flower from the jade box, and put it in the Dan furnace.

Alchemy is based on earth and fire, supplemented by hand decision. But this Extreme Dao Pill is completely different.

It has no fire and no decision, but is refined into a pill with the unity of heart and mind.

The heart flower was put into the Dan furnace, Chu Cheng pinched his middle finger, and a drop of essence blood fell from his fingertips and seeped into the flower, and the pale yellow petals flashed a touch of crimson.

This trace of essence blood is to have a little more sense when refining the pill.

Chu Cheng began to refine the pill, and his mind moved, and he began to refine the Lianxin Flower with that trace of induction.

Under this thought, Lianxinhua began to slowly condense....... This is the first step, the step of Ning Dan.

Ning Dan first, so as to refine, instead of forming first, then Ning Dan, directly skipping the second step.

Time passed, and under Chu Cheng's thoughts, Lianxinhua refined into a yellow elixir.

Chu Cheng was already immersed in this alchemy, this first step seemed very simple, and he also thought it was very simple.

The elixir had already taken shape, and its round appearance appeared in his sight.

The elixir seems to have been made, but under the subtlety, there is still a crack. Just as Chu Cheng used the power of his mind to heal the rift, a roar sounded from inside the Dan furnace. The smell of burnt wafted from the Dan furnace.

"How could it fail?" Chu Cheng was puzzled, this seemed to be the easiest step.

For a person who is about to become a second-level Dan master, Ning Dan is the easiest step, and refining is the most difficult. Generally speaking, the degree of elixir reaches more than 60% before it can be called elixir.

"Careless, do it again. Chu Cheng poured out the dan slag in the Dan furnace and put it back in.

But again, it was still as the last crack was healed, and an explosion sounded.

Once, twice, three times...... It wasn't until the thirty-sixth time that Chu Cheng stopped.

"No! I always feel like something is missing. Chu Cheng frowned, sure enough, as Xue Yu's predecessor said, this is extremely difficult to practice.

A top-level alchemy master only has a one percent chance, Chu Cheng is only a first-level alchemist, and there is still a distance of 108,000 miles from the top, isn't it more difficult to refine the Extreme Dao Pill?

"Snow Rumor Senior!" Chu Cheng stood up and shouted towards the house.

A long time passed, and there was no response. The world is still peaceful.

"That's it, as long as the kung fu is deep, the iron rod can be sharpened into a needle, let alone this. Chu Cheng sighed and sat down cross-legged again. It's just that he didn't rush to practice Dan, but closed his eyes and cultivated himself.

His mood was very irritable, and his mind was full of anxiety. Although there are many heart flowers, there are only a thousand of them, and they can't afford to squander them like that.

According to Chu Cheng's Dan Dao attainments, I'm afraid that ten thousand plants won't even have enough heart flowers. This is just the first step of condensing pills, and the second step of refining is even more difficult.

I don't know how long it took, Chu Cheng suddenly opened his eyes, and a glimmer of light flashed in his eyes.

Chu Cheng looked up at the lake and smiled. At this moment, he suddenly remembered the previous scene.

The primordial space, the primordial blessing, the original snow rumor controlled water to irrigate the spiritual grass, and it grew rapidly in an instant.

"Senior Xue Yu said that refining the Extreme Dao Pill in the Primal Space can increase the chances. I had forgotten about this before!" Chu Cheng looked at the lake, his eyes blazing.

Chu Cheng put a Lianxin flower into the Dan furnace again and began to catalyze it with his mind.

Time passed minute by minute, just as the pill was about to take shape, Chu Cheng pointed towards the lake, and the lake in the distance suddenly splashed, and fell into the pill embryo under the traction.

Suddenly, a thick mist rolled up in all directions, and as the water fell, the surrounding aura rolled in!

At this moment, the last crack on the elixir healed!

Chu Cheng smiled slightly, his expression immediately returned to calm, and he began to refine in one go.

Refining is to remove the impurities in the pill and improve the purity of the pill.

After a stick of incense, an explosion sounded.......

"Failed!" Chu Cheng's face was stained with dirt in this explosion, and his face was pitch black.

This failure is not a failure, the refining just now is just too hasty, and the speed is sped up and leads to the fryer.

Chu Cheng took a deep breath and continued to refine the pill. Refining from Ning Dan is all in one go.

A yellow elixir floated in the Dan furnace, rotating step by step, floating out of a trace of black mist.

After a long time, this yellow pill gradually began to melt......

This is the chemical pill, and it is also the easiest step, after the chemical pill is the sublimation of the pill liquid, the refining of the liquid medicine to the extreme.

An hour later, Chu Cheng exhaled heavily, his body was covered in viscosity and sweat.

When it all melted, Chu Cheng took a little lake, and the lake water was pulled again.

At the same time that this Dan liquid was re-transformed into a Dan, this water liquid infiltrated into this Dan liquid with a thick aura.

A burst of clear light flashed, and the pill liquid began to condense rapidly. Just between three breaths, a golden elixir appeared in front of him.

This is a golden elixir, ordinary and extraordinary. On the outside, it seems to be just a golden elixir, but it contains a rhyme inside.

"It's done!" Chu Cheng received the pill in his hand and smiled with joy.

Although one can only enhance the success rate by half of the percent, as long as there are more of them, even idiots can pile them up.

With the first time, there will be a second time, and it will be much easier.

Chu Cheng took out a jade box, put this Extreme Dao Pill away, and took out another Lianxin Flower to start refining, with the first experience, the next is very skilled.

As time passed, in the jade box where the Extreme Dao Pill was placed, the pills began to increase.

One, two, three..... Four ........

More than a year has passed, and the Dan ash slag around Chu Cheng has accumulated into a hill. But in that jade box, there were more than a hundred Extreme Dao Pills.

"Done!" Chu Cheng took back the last Extreme Dao Pill and smiled. The jade box containing the Lianxin Flower had long been empty, and the last one had been refined into an elixir.

In this year, Chu Cheng failed more than two hundred and thirty times and succeeded one hundred and forty-eight times.

The success rate of a top-level alchemist is only one percent, but Chu Cheng has reached about forty percent, which is also a high success rate.

Chu Cheng stood up, patted the dust on his hands, and came to the lake to wash his body. But when he found that when his hand touched the lake, it was like touching nothingness.

"What's going on!" Chu Cheng exclaimed, this lake water couldn't be touched, but it was obviously able to irrigate the spirit grass.

He then pointed out, and the lake rippled, floating in front of him under the tug of his finger.

"Wow~!" The lake water was scattered in mid-air, and a thick and viscous aura rolled around Chu Cheng.

This aura is very rich, more than a hundred times richer than the inner gate area of the Falling Cloud Sect, and cultivating in such an environment, the cultivation speed can be increased by at least several times. It's a pity that these spiritual powers can only be seen but not touched. It can't be used for it.

"If I can cultivate here, in less than ten years, I will be able to reach the late stage of foundation building!" Chu Cheng looked at this heaven and earth, and his heart was a little hot, but also a little regretful.

"It's just a small piece of soil, and it can't condense all the things in the primordial space. At this moment, Xue Yu walked out of the house, shook his head and said: "With the primordial blessing, the success rate is only forty percent, which is really a waste, if you change that one, it can reach ten percent." ”

Chu Cheng was a little speechless, he was just a nobody, and he didn't even have a foundation yet, how could he compare with the supreme existence of the ancients.

"Okay, one hundred and forty-eight Extreme Dao Pills, although there is only a chance of success, as long as it is not too unlucky, it should be possible. As soon as Xue Yu finished speaking, before Chu Cheng could speak, he waved his hand.

With this wave of his hand, Chu Cheng only felt that the world around him was turned upside down, and a suction force pulled him away from here.

Chu Cheng came to the darkness again in a trance, followed by the sound of falling items around him. It was a jade box filled with the Extreme Dao Pill, and it fell to the ground with a clattering sound.

As soon as Chu Cheng teleported out, he understood what the situation was.

Advanced foundation building requires a large amount of heaven and earth aura, and although the aura in the primordial space is rich, it cannot be absorbed, which is not conducive to foundation building.

Chu Cheng sat down cross-legged and began to close his eyes and cultivate his mind. It's only been a month since the outside world spoke, but a year has passed since the cave.

He refined the Extreme Dao Pill, and every time he dripped, a drop of essence blood was dripping, and it was very draining. It consumed more than 300 drops of essence blood, which was also a big drain of vitality. If you want to advance to the Extreme Dao Realm, you must be in the best condition.

After three days, Chu Cheng, who was on his knees, slowly opened his eyes.

As soon as he slapped the storage ring, piles of spirit stones poured out of it, instantly filling the entire cave mansion.
