Chapter 1786

In less than a quarter of an hour, the first refining ended in failure.

Qin Huan was ready for it. Instead of thinking about it, he stared at the medicine tripod and fell into meditation.

"According to the calculation, you shouldn't have failed. What's wrong?" Qin Huan stared at the medicine juice of the red tripod, which was charred black medicine paste, and fell into meditation.

"The problem of fire?" Qin Huan thought. It was easy to condense the fire with his current ability.

Although there are many herbs in this pill, it is also an immortal pill at most. Therefore, Qin Huan's own flame is enough to refine the pill.

"It should be. Some herbs are not high-grade, and the fire I use can refine immortal herbs. Therefore, the low-grade herbs have been charred," Qin Huan thought.

Although he had been in his mind many times before, some things could not be found without personal experience.

Qin Huan thought again and again about whether there were other omissions, and then continued to refine for the second time.

Soon the second time still failed.

It wasn't the fire, but Qin Huan didn't make it.

third time.

The fourth time.

……

Thirty second.

……

The fortieth time!

As time went on, Qin Huan failed more and more, but he still didn't pay attention to it. Instead, he thought about the reasons for each failure, learned a lesson and continued to try refining.

Although Qin Huan and Xuanyuan Xingchen didn't have much contact with alchemy before.

But their understanding is excellent, and they go to a higher level after combining.

As the times of refining increased, Qin Huan became more and more proficient. In addition, he read many Dan master's letters and used them together. He gradually controlled the feeling of refining pills.

At the 50th time, Qin Huan finally refined it, but the success rate was very low. He only became one.

As usual, a furnace of pills can produce several pills, up to nine. Now, it has only become one, and it is still scorched black and oval.

At this time, Qin Huan took the only successful one, and his face was a little complicated. Although it was refined, I'm afraid it was only 10% at most.

To put it mildly, this pill can only be a semi-finished product, which is far from the top-grade pill.

"At least 50% can be regarded as top grade..." Qin Huan whispered, staring at the Dan Ding and began to meditate.

"According to the records, according to the way recorded in many books, there should be no mistake. Why can it only exert 10% of the efficacy? Is it my wrong order?" Qin Huan began to consider the order in which he put the herbs and began to adjust them.

In this way, Qin Huan was refining, thinking and bumping. At the sixty fifth time, he finally refined a pill that had a 20% effect.

"Twenty percent, but there are only thirty-five chances. If you go on like this... It's almost impossible to be promoted to the top grade!" Qin Huan took the pill in his hand and looked helpless.

As long as enough alchemy materials are given to him, he is sure that he can refine 50% of the pills after many attempts, but now there are only 35 times.

Holding the pill, Qin Huan slowly closed his eyes and remembered the Danto books he had seen in 49 cases.

Although he remembered a lot, he didn't fully understand it. Therefore, he still needs to recall and ponder when necessary.

"Wait... Can I join my own strength into the pill? Can this improve the efficacy of the pill?" Qin Huan remembered that an ancient book had mentioned this.

Without much hesitation, Qin Huan continued to refine pills for the sixty sixth time.

This time, Qin Huan was adding the power of nature, the weak power of God and the holy power of spirit. These three forces contained the power of vitality. The others were violent. Qin Huan did not dare to join rashly.

Half an hour later, Qin Huan looked at the two elixirs in the tripod and smiled: "two, 30% effective!!"

Qin Huan was bitter and astringent. Although three forces were added, the efficacy increased to 30% and became two pills, it was still far from 50%.

Although there is only a small gap of 20%, it is as far away as a natural graben.

"Increase by 20%!" Qin Huan took a deep breath and his eyes gradually became firm.

"There must be a place I don't master. I must refine the top-grade pill!"

Qin Huan sat down and thought about the order of herbs and the heat. He thought about the books he saw again and again to see where he could improve.

Qin Huan would not continue refining until he thought about it again and again.

However, the difficulty of refining pills was far beyond Qin Huan's imagination. Ordinary Dan masters wanted to improve the efficacy by 10%. I don't know how many times it would take to refine pills, let alone 20%?

Therefore, it was almost impossible for Qin Huan to improve his efficacy to 50% in a short time.

After much deliberation, Qin Huan continued to refine.

Seventieth time.

"It's improved a little, but it's not enough to achieve 40% efficacy!!" Qin Huan looked at the pill in his hand. He was helpless. He had thought over and over again and further adjusted the order and heat. Although the pill improved a little, it was not enough to reach 40%!

"Since someone can refine top-grade, top-grade and even perfect pills, there must be deficiencies in some places, so they can't be improved. But where are they missing?" Qin Huan took a deep breath, closed his eyes again and searched carefully for his memory.

A long time later.

Qin Huan opened his eyes and began refining again.

"The order in which I put herbs is based on their own efficacy. It shouldn't be a big problem, but I ignored one point, that is, if some herbs can be put in at the same time, they will have better efficacy," Qin Huan said to himself.

He tried to put the herbs in at the same time.

In this way, Qin Huan thought over and over again, constantly overturned the reason and improved it.

In his 90th refining, he successfully refined a pill with 40% efficacy.

At this time, Qin Huan was holding a pill with a faint light and clouds, and looked at the only ten groups of herbs floating in the air, not only crying and laughing.

Forty percent. Not long after I really came into contact with the pill, I successfully refined the pill with forty percent efficacy, which can cause a sensation in shuangshenzong and xumitian.

But now, Qin Huan had no complacency and was helpless.

It was 40%, only 10% away from the top-grade pill, but Qin Huan couldn't see hope.

"I don't believe this success can stop me!" Qin Huan looked at the vulture and closed his eyes again, pondering over the records he had read.

Ten days later.

Qin Huan refined pills again. This time, he not only poured the power of nature, God and soul into pills, but also poured his own blood into pills.

This is an assumption in a certain record of 49 Dan pavilions. Qin Huan had no other way but to try.

But as a result, it ended in failure again!

Qin Huan continued to think and try again and again.

Ninety second time, failed!

Ninety third time, failed!

Ninety fourth time, failed!

……

Ninety seventh time, fail!

98th time, fail!!

The 99th time, Qin Huan, who was no longer hopeful, spewed out a mouthful of soul blood when refining pills. He was at a loss and had no choice but to place his hope on his own soul blood.

This time, with the roar of the dragon, a pillar of light rushed out of the Dan Ding.

"If the top-grade pill is successful, you can get extra rewards." the old voice echoed in the sky.

Qin Huan's pale face finally showed a happy smile.

At the same time, on the stone tablet on the fourth floor, the name of Xuanyuan star appeared, still sitting under heaven and God Dan Zi.
