This is the most important and most difficult step in alchemy. This step needs to reconcile the medicinal properties of all the elixir, and also uses a lot of spiritual power to flush out the impurities generated when the elixir is fused.

Rong Cheng failed in the Rongdan step two times before, which shows the difficulty of the Rongdan step.

Rong Cheng let out a sigh of relief, swallowed two Spiritual Returning Pills again, and closed his eyes, but his consciousness was always paying attention to the pill furnace, and the seals of his hands were pushed out.

The pure spiritual power of the wood element awakened the spirit gathering formation in the alchemy room, and each area of ​​the formation was lit up in sequence. Yinyuezong alchemy room built-in

The pill furnace fell on the eye of the formation, and the spiritual energy of heaven and earth absorbed by the formation was purified by the formation and gathered into the pill furnace.

However, the formation engraved under the alchemy room of Yinyue Sect is too rough and simple to effectively remove the impurities in the spiritual energy of heaven and earth. After the spiritual energy enters the elixir furnace, it needs to be refined again by the pharmacist before it can be poured into the elixir that is being formed.

And the elixir refining has reached this step. The alchemist is already very tired.

Therefore, the more subtle the formation, the more it can reduce the burden on the alchemist. It is a pity that the Yinyue Sect does not have any cultivators who are skilled in the formation of formations. Although all formations are not at the level of shoddy production, they are not of any help to the alchemists.

Outside the alchemy room, in addition to the disciples of the Silver Moon Sect, there were also the disciples of the Qingshui Sect who were less injured. They were waiting outside the alchemy room, staring at Rong Cheng in the room through the window, and their eyes spread a bit. hope.

These disciples who have fled, the injuries are not life-threatening. If there is no medicine for treatment, there will be hidden dangers that affect the foundation.

If this young pharmacist can refine a fourth-grade medicinal pill, then they might be saved.

At this time, the sun was already in the west, and this new elixir had been refining for a whole day. The bitter taste of the elixir mixed together had already become sweet and greasy under the refining of the fire.

Just smelling the smell outside the window will make you feel comfortable.

The chief disciple of Qingshui Sect was in ragged clothes, and he cautiously asked the disciples of Silver Moon Sect around him: "Fairy, is this medicine going to succeed?"

The Yinyue Sect disciple looked solemn and shook his head slightly: "Not yet. But it's the end, if... it's not good!"

The Qingshui Sect disciple looked over in a panic——

I saw a flash of fire breaking through the top of the furnace, the black iron furnace cover collided with the dome, and with the rumbling sound, the splashing sparks and stones fell at the same time!

A cyan flame emanated from the furnace, and after the furnace cover flew off, it was torn apart in the alternation of cold and heat - the flame had eaten up enough spiritual energy, and it was completely out of control!

Hong Qin raised her hand to cover her face, the sparks splashed around to see her sleeve fall to the ground, Hong Qin stared blankly at the flames rushing up to the roof: "How...why is this happening?"

The spirit gathering array in the alchemy room flashed wildly, and the onlookers with the burst of aura all avoided their sight.

Rong Cheng's pointed tiger teeth gently cut into her lower lip, and blood slid down the corners of her lips. She hadn't rested for a few days, and her eyes were bloodshot.

"It's the Spirit Gathering Array."

Rong Cheng immediately found out the reason for the explosion of the Dan furnace.

The formation of the alchemy room has been unmaintained for a long time, and the aura required to refine the fourth-grade medicine pill is too large. After a long time of operation, the aura broke into the gathering formation, and all the heaven and earth aura originally accumulated in the formation rushed into the medicine. furnace, causing the fire to get out of control.

The sky-high flames startled everyone outside the alchemy room - when Rong Cheng's first batch of elixirs failed, there was no such big commotion!

"What's going on here? "

"The lid is fried!"

"The pill furnace seems to be cracked..."

"What about this? Is it going to fail again?"

The Qingshui sect disciple's eyes were splitting, and his hands tightly clenched the window frame, "Failed again?! What should do, junior brother and junior sister..."

Outside the alchemy room, Yinyuezong's alchemist was on the ground with his hands on the ground: "This furnace is bound to be abolished."

The moment the flame rushed out of the Dan furnace, it was almost the same as the explosion of spiritual power. The unprecedented elixir could inevitably be kept. Even if there was no broken crack, it had been contaminated by the heaven and earth aura that was not refined.

Disciple Qingshuizong glanced back, his eyes touched the embroidered pattern of the Dan furnace on the other's chest, and the last hopes in his eyes slowly extinguished.

When the alchemist outside the alche room, the alchemist cleared his nails. When everyone was discouraged, he relieved quietly and twisted the beard: "It's not surprising that it is not surprising that the real Yuan Dan is refined in the four -pine elixir. One of the most difficult types is that Rong Xianzi is still too young. don’t know the difficulty of refining different elixir in each grade. "

Although there are not many worships of Yinyuezong, the pharmacist is just a four -product alchemist, and can only refine the simple four -product elixir. If you leave Yinyue Zong, it is difficult to find a stable place to live.

It can be seen in a short time that Rong Cheng has not grown up, and Yin Yuezong still needs these pharmacists to prefer the pharmacist.

Yin Yuezong's disciples are more concerned about Rong Cheng's safety: "Since it failed, would Mirror Rong be rejected?"

The medicine refining artist's head: "Yes, even if a new pair of elixir is prescribed, Rong Xianzi will not be able to prescribe the furnace again. At this time

However, in the alchemy room, Rong Cheng did not accept the support of Hongqin. She pushed the red celestial, her hands became round, and calmed the boiling spiritual power in her body.

The pharmaceutner frowned: "She: What do you want to do?"

Although Rong Cheng has not reached the point of exhaustion, but for a few days, he has concentrated on the use of elixir, which has consumed a lot of energy. Tightening: "knot!"

Under this order, the trend of flames spread suddenly!

Rong Cheng's blood -filled eyes were extremely bright. She spoke again, her slender fingers slowly clenched, her fingertips seemed to be forcibly pulled, and her fingertips were white, so that the movement of a finger was so difficult :"Knot!"

The flame seemed to be restrained in the thin finger, no longer flooding outward, the spiritual power was woven into an invisible net, gathered the flames, forming a huge cocoon, the dispersed flames gathered in a ball, and the formation was rising. The source of the aura is injected into the cocoon of the flame.
