Since he was going to try to refine the Sacred Heart Guiyuan Pill, it was useless to continue to stay in the Guiyi Sect.

After Zhang Zhixuan and Qing Chan returned to the Ziyang Sect, they came to Tianyuan Island through the intercontinental teleportation array, preparing to use the Shanhe Ding.

The Ziyang Sect did not have a sixth-order alchemy furnace, and the best alchemy furnace was the mountains and rivers left by the Tianyuan Sect. This tripod was forbidden by the formation on Tianyuan Island, and it couldn't move a single point at all.

This magic weapon can be used for both purposes, and the grade is the fifth order. It is used to refine Sister Liu's elixir, and it is still a little insufficient.

The sixth-order elixir is the spirit treasure of heaven and earth, and it is often difficult to turn it into a medicinal liquid, although Zhang Zhixuan has pure yang true fire, the ordinary fifth-order Dan furnace is likely to not be able to withstand such high temperatures.

However, the refining method of this magic weapon is special, although it is limited to one location, the attached protection and prohibition make this magic weapon less susceptible to damage. According to Zhang Zhixuan's estimate, it is barely enough.

Moreover, Zhang Zhixuan's pure yang true fire has a great help effect on alchemy, but how to master the proportions, he still has to study his alchemy.

The reason why Zhang Zhixuan took the risk of refining the Sacred Heart Guiyuan Pill was also for You Nianwei, Wang Chengxiang and other people whose vitality was greatly damaged.

Tang Fenglan and Lu Hongniang's qi sea were damaged, even if they took the Sacred Heart Guiyuan Pill, it didn't have much effect.

Zhang Sihong and Zhou Huayang's physical bodies are mutilated, even if they are reconnected, they look intact, but the meridians and acupoints are seriously damaged, and they can no longer withstand the toss. The cultivation of monks requires the operation of Zhou Tian, and if there is no strong energy in the meridians and acupoints, it will be difficult to make an inch of progress in cultivation.

Wang Chengxiang and You Nianwei, the two golden pills, need to recuperate for hundreds of years if they want to replenish their vitality. If you take the Sacred Heart Guiyuan Pill, you can save at least two hundred years of work. Wang Chengxiang, who was slightly injured, could even recover quickly, and after You Nianwei took it, he could also practice two hundred years in advance.

"Now you deduce three plans, there is only one elixir for refining the elixir, do you want to wait for a while?"

Zhang Zhixuan shook his head and said: "Pharmacologically speaking, the three schemes can all make sense, I estimate that they can all refine the real elixir, but the two elixirs may be fifth-order, and using two sixth-order elixirs to refine the fifth-order elixir is not a success."

Inventing a sixth-order pill requires countless efforts, and it also requires a lot of elixir costs. The same is true for restoring the incomplete Danfang, if you don't practice it yourself, you can't succeed. Even if I lose something, I think it's something to bear. ”

Over the years, Zhang Zhixuan and his wife have accumulated tens of millions of good deeds in the Ziyang Sect, and the Jiuyang ginseng is still what they have obtained from their adventures outside, and the exchange for a sixth-order demon pill only consumes one-tenth of the good deeds of the two of them.

Moreover, when the cultivation reached their level, good deeds could only play a small role, and if they could break through to the sixth-order alchemist, it would also be a great benefit to Zhang Zhixuan.

Qing Chan frowned and said, "Why don't you let Lingjun find the Shenshui Palace, the Shenshui Palace has a sixth-order high-grade alchemy furnace, if you use the Shenshui Palace Alchemy Furnace for alchemy, it may be easier to succeed." ”

Refining the elixir not only requires the quality of the alchemist itself, but also various external conditions, such as the Dan furnace, the furnace fire defense ban, etc., any subtle link that has a problem may lead to failure.

Therefore, the preliminary preparations for refining high-level elixirs must be done very sufficiently.

"I've thought about it carefully, the pure yang true fire is already equivalent to the sixth-order spiritual fire, even if the mountains and rivers are a little bit almost only the fifth-order top-grade, the external conditions for refining the sixth-order lower-grade spirit pill are enough, as long as the Danfang is not negligent, according to my current alchemy, it should be possible to refine the spirit pill."

Nowadays, the spirit pills above the fifth order of the Ziyang Sect are all refined by Zhang Zhixuan, and sometimes some fifth-order spirit pills are even refined and sold in the market.

Over the years, he has refined more than 100 fifth-order elixirs, and one person has monopolized a sect's high-level elixir, and his alchemy experience has far surpassed that of ordinary people.

Not counting the Sacred Heart Returning Yuan Pill, the Purple Yang Sect's sixth-order Dan Fang treasured two kinds.

One is from the Song Kingdom Danyang Sect Sanyang Yiqi Dan, and the other Dan is even more precious, it is the famous Sanying Spirit Pill Peiying Pill in the immortal cultivation world, and the grade of this Dan is already the sixth order of the middle grade.

Whether it was the Sanyang One Qi Pill or the Peiying Pill, the Purple Yang Sect had not collected enough elixirs.

Taking the risk of refining the Sacred Heart Returning Yuan Pill was already the only shortcut for Zhang Zhixuan to break through the sixth-order alchemist.

Although refining this elixir required taking a lot of risk, Zhang Zhixuan had already made up his mind.

Even if you lose the elixir worth millions of spirit stones, you have to open the furnace for alchemy, and even if the refining fails, you can also rule out a possibility.

After making all the preparations, Zhang Zhixuan completely sank his mind into the alchemy furnace.

According to the pharmacological properties of the pill, Zhang Zhixuan carefully put the elixir into the alchemy furnace in order.

He cautiously sacrificed the pure yang true fire, began to extract the medicinal liquid, repeatedly thought about his every move, and groaned secretly in his heart to see if there was any possibility of missing.

It takes a long time to dissolve the sixth-order elixir, and it takes three years to refine the sixth-order demon pill.

Zhang Zhixuan's mana is enough, but Shanhe Ding is a fifth-order high-grade alchemy furnace after all, once it can't withstand the high temperature for a long time and the Dan furnace explodes, it will also give Zhang Zhixuan a headache at that time.

Zhang Zhixuan carefully controlled the mana, and his divine sense stared at the mountains and rivers almost for a moment, he would rather drag it out a little longer than seek stability.

Qing Chan has arranged strict and thorough forbidden methods outside the alchemy room to prevent the worst. Once the Dan furnace is blown up, it also avoids hurting innocent people.

Looking at the sparkling demon pill, Zhang Zhixuan let out a sigh of relief and suppressed his impatience.

He pinched the magic trick in his hand, and constantly played out one prohibition after another on the mountains and rivers, these prohibitions included those that protected the Dan furnace, some isolated the temperature, some increased the temperature of the furnace, and some urged the Dan furnace to rotate.

The temperature of the pure yang true fire was amazing, and it soon burned the mountains and rivers completely red.

At this time, Zhang Zhixuan was more cautious, staring at the temperature of the furnace all the time.

The heat wave of the Dan furnace is rolling, and the two halos of light, one blue and one red, rotate and linger, and it looks extremely amazing.

Zhang Zhixuan carefully controlled the mountains and rivers, and after four and a half years of refining, he dissolved the demon king Neidan. The reason why it took an extra year and a half was because the Shanhe Ding grade was not enough, and Zhang Zhixuan needed to be careful all the time, and he didn't dare to urge the pure yang true fire too much.

The demon pill dissolved, and the remaining Jiuyang ginseng was easier, and after another year and a half, the two-flavored sixth-order elixir finally melted in the Dan furnace.

has been sleeping for six years in a row, even if he has become a Yuan Baby, it has made Zhang Zhixuan very tired.

It's a pity that at such a critical time, he can't rest at all.

The next two steps of Yangyuan and Ning Dan need to be very careful.

A stream of medicinal fragrance emanated from the mountains and rivers, and when he smelled this strange fragrance, Zhang Zhixuan immediately showed a smile on his face.
