First of all, the refining is naturally the relatively simplest "Yunshen Pill".

Fifty copies of materials were copied from the stone mirror and flew into the fifty holes, consuming tens of thousands of crystals in one go.

Clouds of altered earth fire erupted, and a scorching aura filled the entire cavern.

Fifty distractions are almost to Lu Yuan's limit, if it weren't for the fact that he had deceived Zhao Heng with his illusion before, which made his illusion improve a little, he wouldn't have been able to do this at all.

"Fifty of yourself, all refining the same elixir, and learning from each other, can not only reduce pressure, but also maximize the level of alchemy."

This is Lu Yuan's idea.

To have fifty of them refine different pills by themselves, he couldn't do that with his current ability.

In order to prevent the same problem from happening at the same time, each furnace is spaced 10 minutes apart.

As the same ingredient flew into the furnace, the rich flavor escaped.

A moment later.

"Hum" The first Dan furnace suddenly exploded, and Lu Yuan, who was sitting in front of the Dan furnace, muttered to himself: "Is the fire too great?" It should be slightly smaller. ”

The other Lu Yuan instantly received the information and began to adjust the firepower.

After a while, another furnace was destroyed.

"According to Danfang, the order of the materials is fine, maybe it's the time to put it."

"No, the impurities haven't been removed."

"Huh? What's wrong with this furnace? ”

After destroying several furnaces in a row.

"I see, the problem arises in using Yuan Force to sort out the properties of medicine......"

One problem after another, a little bit of experience continues to accumulate.

A whole day has passed on Jupitus, fifty furnaces have been refined, forty furnaces have been refined, and only ten furnaces are still holding on, and it will take two more days before the refining is successful, and it will almost certainly fail.

However, Lu Yuan's face was much more confident than before.

Originally, I just came up with a way to save time, but I didn't expect the effect to be obvious.

If you had thought of this method earlier, maybe the Nine Yang Tibetan Divine Pill might also be refined.

"Failure is worthy of the mother of success, as long as there are enough failures, you will definitely succeed!"

Although that being said.

But there are not many people who can do this, first of all, the material is limited, and many materials are difficult to collect, such as the Jiuyang Tibetan Divine Pill, Zhao Heng has collected it for so long, and only one copy has been collected.

In addition, there are financial limitations, and copying with a stone mirror can reduce the cost by half.

Finally, there is the limitation of time and talent, how many people can control the spiritual power like Lu Yuan, and can separate so many phantom bodies?

The next day, all the fifty furnaces of pills were finally refined.

Lu Yuan was not angry at all, and directly used the Yuan Crystal to recharge, and then absorbed the energy in the stone mirror to recover the consumption.

Subsequently.

Copy a bunch of materials from the Divine Pill again and continue with the next round of experiments.

Two days later, another fifty furnaces of pills were refined, but to Lu Yuan's delight, he had been able to hold on to the last day smoothly, and a lot of experience had accumulated in his heart.

It is a full failure of a hundred furnaces, and it takes at least hundreds of thousands of yuan to change into normal materials, and it is very difficult to gather so many materials, throughout the ages, there are few sects that will provide a rookie alchemist to practice at such a cost.

Nine days later, in the early hours of the morning.

After two hundred and forty-five furnaces in a row, the refreshing medicinal fragrance of one furnace emanated from the remaining furnaces, some faint and some rich.

When the hour comes.

Lu Yuan raised his hand decisively, the five furnace lids flew away, and five strands of pill liquid flew out of the furnace, Lu Yuan rubbed it in the air, and immediately turned into five pills and flew into his hand.

Lu Yuan stared intently at the pill in his hand, and after a long time, four of the pills appeared white moire in different states.

Two of them have reached the mid-grade level, and the other two have moire all over the majority, which is suddenly a high-grade grade.

"One low-grade, two medium-grade, two high-grade!"

Lu Yuan was excited, the most excited thing was not to refine the top grade, but to succeed in the last five furnaces, he already knew everything about the Yun Shen Pill, and it had been engraved into his mind, and he could have a great success rate no matter how he practiced.

Not only that, but practicing this top-grade pill for a long time and in large quantities has made his alchemy progress by leaps and bounds.

It is equivalent to graduating from elementary school and reaching the level of junior high school.

"The task assigned by the sect master has been successfully completed by one-third. However, the remaining two pills are more difficult, but fortunately, the alchemy has improved. ”

Lu Yuan thought about it, took back all the clones, crossed his knees and closed his eyes, and recuperated physically and mentally.

Maintaining so many phantom bodies in a row, even if there is a stone mirror to replenish energy and willow wood to assist, the mental pressure is still extremely high.

A full day of rest.

Lu Yuan's eyes lit up, and one phantom body after another reappeared, and one by one the materials were copied out.

"The second elixir - Rejuvenation Pill!"

Time passed slowly, and with the refining of a furnace pill and the accumulation of a little bit of experience, Lu Yuan's cognition of the Recovery Pill became clearer and clearer.

This elixir is not helpful for improving the realm, but it can be said that it can become the second life of Xuan Xiu to a certain extent, and the difficulty has increased significantly, even if Lu Yuan's alchemy is rising, within a hundred furnaces, it still has not succeeded.

……

Outside the alchemy room, inside the Qingyun Sect.

"Senior Brother Tang, have you heard, Elder Lu is back, and now he is helping the sect master refine the pill."

"I also heard that it was the Sect Master who did not hesitate to collide with the Zhao City Lord of Linfeng City to bring Elder Lu back, alas, I am afraid that we will be troubled when we go to Linfeng City in the future."

"Who said it wasn't, is the sect master obsessed, with Elder Tong here, what are you worried about."

Beside Tang Yu, who had a pointed chin, the two male disciples said one word at a time.

Tang Yu's face was gloomy, because he offended Lu Yuan, he was punished by the sect master to suppress the earth fire, and he was only released in the past few days.

During the days of suppressing the earth fire, the physical torture was secondary, and the most painful was psychological, his disciple of the elder Tong, who was still the highest alchemy of this generation, and the future alchemy master, was actually punished in public, it was a naked slap in the face, and the beating made a crackling sound.

Originally, I was going to complain to Shizun after coming out, but I didn't expect that Shizun had been alchemizing pills and couldn't come out of retreat.

"Shut up, don't mention that person again!" Tang Yu roared.

The two glanced at each other, and one of them smiled and said, "Senior Brother Tang, you shouldn't be afraid of Elder Lu, right?" ”

"I'm going to be afraid of him? There is definitely something wrong with him, his alchemy is definitely fake, and when the master comes out and faces him, it will be when he shows his true colors! Tang Yu gritted his teeth and said.

……

The main hall of the Qingyun Sect.

Hong Ling looked at the direction of the bamboo forest villa, a little distracted.

"Master, Master......"

Hong Ling came back to his senses and looked at Su Jiao below, "What's the matter?" ”

"The Yuan Jing that maintains the sect's formation can only support it for two more days, and some fellow sects have discovered that there are still Xuan Xiu lurking outside, I'm afraid it's not good for our Qingyun Sect." Su Jiao reported truthfully.

Recently, the sect's formation has been stimulated to the strongest level, and the daily consumption is several times that of before.

"Got it."

Hong Ling's hand touched her waist, but she felt empty, her face was stunned, and then she remembered that all the Yuan Crystals on her body were given to Lu Yuan.

She thought about it for a while, touched her space ring, took out tens of thousands of yuan crystals from her private vault, transferred them to a space bag, threw them to Su Jiao, and advised: "Let people pay attention to it and inspect the surroundings more." ”

"Yes, Master."

Su Jiao took it and did not leave, but stood in place with a hesitant expression.

"What else?" Hong Ling asked.

"The disciple heard that Elder Lu and Elder Tong are both alchemizing, I wonder if it has something to do with the current situation of the sect?" Su Jiao replied.

Hong Ling let out a "hmm" and looked at Su Jiao thoughtfully, knowing that this apprentice still had nothing to say.

Su Jiao lowered her head and muttered, "The disciple has nothing to do recently, I want to go and help the elders......
