"Duerdan, Gu Feng, are you sure you're not wrong?"

Zhang Xiu's eyes widened, staring straight at him, his breathing couldn't help but be a little dignified, and the look of surprise disappeared in his eyes, revealing a look of fiery expectation.

Su Yixuan, who was veiled and demure and elegant, couldn't help but look at him in surprise, her eyebrows flickered, as a student of the Fengshen Academy, she naturally knew about Du Erdan, not only she knew, but many elders and students in the academy knew.

Ten years ago, an elder of the academy was attacked by aliens in Zhonghai, and then he was seriously injured by the demons, and returned from death.

At that time, a Supreme Elder in the academy, who was good at potions, personally took action, and there were five or six potion masters on his side to assist, to refine the Du Erdan, which was about to enter the rank of the six grades, but the result was still in vain.

To this day, the Supreme Elder is still suffering from sleepless torture.

Not only the Fengshen Academy, but also the entire Southern Wilderness Continent, no one has successfully refined the fifth-grade Dou Erdan for more than ten years, but there are many Martial Emperors and Fadi who have suffered from the backlash of the demons and failed to advance.

If Gu Feng can successfully refine Du Erdan, then he will become a hot figure in the eyes of the major forces in the Southern Wilderness, and his prestige is not even weaker than that of the Southern Emperor, the lord of the Southern Wilderness.

You must know that although Emperor Wu and Emperor Fadi are a moat that has cut off the way of promotion for many people, how many human beings are there in the Southern Wilderness, and there are many amazing generations, coupled with the long-standing secret family, there are not many Emperor Wu and Emperor Fadi.

Even if the Arras family has declined more than twenty years ago, there are still eight Martial Emperors and Fadi in the clan, which shows how huge the strength of other hidden families that have been inherited for thousands or thousands of years. How many Emperor Wu and Emperor Fa are there.

The path of cultivation is full of hardships and dangers, and if you are not careful, you will fall into the abyss. There were a lot of people who needed to cross the Edan area, which was one of the reasons why they were shocked.

Other than that. Although Du Erdan is a fifth-grade high-grade elixir, it is even more difficult to refine than a sixth-grade lower-grade elixir, and it can be said to be among the best among the five-grade Tongling Treasure Pills, and is even called a divine pill.

The materials are rare, the main drugs are all five and six grade of medicinal materials, and the auxiliary drugs are also not at all rare than the main drugs, there are more than 300 kinds of various grades of medicinal materials, which are very troublesome and laborious to collect.

Du Erdan has very strict requirements for the year and efficacy of each medicinal material, and the number of years cannot be less or more. If you have five more years, you can't use it, of course, the requirements for pharmacists are stricter, and if you don't have a grandmaster level, please don't open your mouth, even if the pharmacy grandmaster hasn't heard of anyone in the Southern Wilderness who has successfully refined the Erdan.

His eyes swept over everyone's shocked faces, and he was not the slightest surprised by their reaction, nor was he at the Dan Fang of Du Erdan, but when he found out about Arthur Mulan's condition, the word 'Du Erdan' suddenly popped up in his mind.

Then, a stream of memories came to mind. He understood what was going on. The extra memory was none other than someone else's, it was the memory of a great potion master of the Arras family about the Elder Dan.

Although this senior failed to successfully refine the Crossing Erdan, he had a deep understanding of it, and before he died, he successfully refined the half-finished Crossing Erydan. It was because of this sudden memory. Gu Feng dared to speak.

"Yes, it's Doodan. However, the medicinal materials required to refine the Douerdan are extremely complicated—"

Before Gu Feng finished speaking, Zhang Xiu, who was so excited, couldn't help but interrupt: "Senior Brother Gu Feng." The Doerdan side is not top secret, and of course we know that the materials are complicated. You just say that you are so sure that you are refining Du Erdan?"

glanced at Zhang Xiu in surprise, I don't know why he was so interested and excited. But he ignored it, slowly closed his eyes, and opened his eyes again after a while, and said with a firm and confident gaze: "At least seven layers!"

"Okay, good, great, grandpa is saved!"

The seventh-layer grasp is already an extremely high grasp of refining the five-grade or higher Baodan, and the seventh-layer grasp of the three materials has to come up with one.

Zhang Xiu trembled, tears flowed out of his eyes with excitement, ignoring everyone's strange gazes, he grabbed Gu Feng's hand and said: "Senior Brother Gu Feng, as long as you can refine Du Erdan and cure Grandpa, my Zhang Xiu's life is yours!"

At this time, Gu Feng was a fool if he didn't understand what was going on, and when he saw Zhang Xiu's actions like this, he really understood the horror of Du Erdan, and an idea suddenly popped up in his heart, if he used Du Erdan as a guide, it was not impossible to recruit strong reinforcements for the Arras family.

Although most people say that Emperor Wu and Emperor Fadi have families, you can be a guest secretary in the Arras family, and it is not too much to contribute at a critical time. Besides, being able to be on the list of a great potion master, not to mention just being a guest, even if they are attached to the Arras family, it is not impossible to consider.

"Senior Brother Zhang Xiu, there is no need to be like this, we are both students of the academy, so we don't need to be so polite. As long as the materials are complete, the junior brother will naturally do his best to refine Du Erdan, and he will be a good old-timer!"

Gu Feng comforted, if he really agreed, wouldn't it be taking advantage of the fire to rob and attack his own people. Zhang Xiu is a bright and upright person, and he is also quite admired by the ancient style, and he is willing to associate with him.

Hearing this, Zhang Xiu was very moved, and secretly swore in his heart that in the future, Gu Feng would die if he needed it, and he would desperately repay him, and hurriedly said: "Senior Brother Gu Feng, I'll go back and bring the materials, so I'll trouble you to wait for an hour or two." ”

After that, he ignored everyone, and rushed out of the hall directly towards the Nobel Mountain Teleportation Array, the Zhang family is also a big family, and there are also two Martial Emperor powerhouses in the clan. However, his grandfather has been guilty for many years, if he can recover this time, the strength of the family will definitely increase greatly, how can he not be in a hurry.

Zhang Xiu left, and some of the Martial King students in the hall also wanted to leave, but after thinking about it again and not leaving, it was better to wait and see if he really refined the Crossing Erdan.

Gu Feng looked at Duanxiong and said, "You know all the materials for Du Erdan, although I promised to save him, but you also have to make up the materials yourself." When you have all the materials, I will start alchemy, please go back!"

Duanxiong's face was embarrassed, it could be seen that he was resolute, and he regretted it even more in his heart, and finally shook his head, turned around and waved his hand at the two clansmen, and walked out of the hall.

Two hours later, Zhang Xiu came to the door again. Only this time he was not the only one who came, there were two middle-aged people and an old man in a wheelchair. The two middle-aged men look very similar to Zhang Xiu. One is his father Zhang Jie, and the other is his uncle Zhang Yang. That old man was naturally the grandfather in his mouth.

"Senior Brother Gu Feng, all the materials have been taken, and I can barely make up four points, can you please check if there is a problem?" Zhang Xiu waved his hand excitedly and worriedly, and a storage ring appeared in the palm of his hand and handed it to Gu Feng.

With a wave of his hand, his spiritual power probed into it, and after a while, he was very surprised in his heart, and he had to sigh that the foundation of the big family was behind him. Looking at their nervous expressions, he smiled slightly: "Yes, the medicinal effect is very suitable, and there is nothing wrong." ”

"There is a high priest of Lao, and the extra one of the four materials will be given to the high priest, and after the matter is completed, the Zhang family will have another generous reward. If the Arras family needs anything, they can send someone to inform them. The Zhang family will definitely come. ”

Zhang Jie arched his hand at him and solemnly promised, feeling equally nervous, apprehensive, and secretly happy. sighed that his son was lucky to be able to become friends with the great master of medicine, but more of it was ecstatic.

"Uncle Zhang is polite. Senior Brother Zhang is my brother, don't talk about any good rewards. However, if a foreign race comes to attack and can send a few people to come, Gu Feng will be grateful. ”

The ancient style is very polite. He is that kind of person, I am naturally good to you if you are good, and it is also very good to be able to make friends with the big family of the Zhang family.

After a polite referendum, Gu Feng led them to Nobel Mountain, where it was safer to have an infinite array. On a spacious and smooth boulder halfway up the mountain, the ancient style sat cross-legged and motionless. Surrounded by Zhang Xiu and a group of students, the three members of the Zhang family, and the idle little Lori grandmother.

Although there are memories of the ancestors, but also turn into their own experience, otherwise it will be wrong, in the Bodhi world, hundreds of thousands of ancient winds at the same time on a piece of Bodhi leaves to comprehend, carefully study, calculate every step, can not have the slightest mistake.

Half an hour later, Gu Feng suddenly moved, opened his mouth and spit out, and the fire heart flame erupted to form a seven-petal fire lotus in the air.

Zhang Xiu and Zhang Jie had never seen Gu Feng so alchemy, and they held a handful of sweat in their palms, for fear that he would accidentally scrap all the materials, not to mention four medicinal materials, even one hundred and one thousand copies were not enough. Collecting the medicinal materials of Du Erdan cost them more than ten years of hard work and huge wealth.

And Mo Wu was brutal and profitable, Li Mu and the others were full of excitement in their eyes, looking at the ancient style alchemy was like watching a wonderful juggling, which made people dizzy, and their whole hearts couldn't help but beat with it.

The spiritual power covers a range of 20,000 meters, and I am afraid that no pharmacist has been so terrifying throughout the ages, and the calculation has been completed in his mind, and the ancient wind is naturally like flowing water, extracting the medicinal liquid, removing the dregs, improving the efficacy of the medicine, and with the help of Huoxinyan, it is even more relaxed.

Although Du Erdan is a fifth-grade high-grade elixir, it is very difficult to practice, but in the eyes of the freak of Gu Feng, it is also a bit of a challenge, and the seventy-two scattered cloud hands continue to shoot out at the right time, and every time one hand is shot, there will be a more intense medicinal fragrance from the seven-petal fire lotus.

The aura of the endless heaven and earth was shot out one by one, gathering from all directions, forming torrents of aura that were entrenched above the head of the ancient wind, forming a large vortex of spiritual energy.

In the end, a glittering goose egg-sized pill appeared in the center of the fire lotus, which had shrunk more than ten times. Gu Feng's expression became a little solemn.

When the sixty-seventh path of scattered clouds was slapped down, a torrent of spiritual energy flew out of the whirlpool, and a swirling fist sank into the pill, and the light of the goose-egg-sized pill flashed, and there was an extra line full of spirituality on it.

After that, with each hand, a torrent of spiritual energy will submerge into the pill, and an extra spiritual pattern will appear on it. The dark clouds above his head rolled, suppressing the torrent of spiritual energy, and an invisible restraint descended, and a rumbling and low voice sounded on Mount Nobel.

"The Thunder Tribulation is coming!"

Looking at the almost formed Du Erdan, the hearts of the people around him became hot, looking up at the rolling black clouds, and secretly said in their hearts.
