"Fire System-Materia Medica" records that most of the soul grasses in the Tianlong Continent for thousands of years, there are more than 7,000 kinds, compared to the rhythm, it is much easier to remember these soul grasses, in less than four hours, the form and medicinal properties of 7,431 soul grasses have been imprinted in Yuan Feng's mind.

As Wen Zhenghan said, the lunch was delivered on time, the meal was not rich, but it was extremely delicious, and after the meal, Yuan Feng put into the comprehension of "Fire System - Materia Medica", the more refined the power of the fire system The success rate of alchemy is also very significant, "Fire System - Materia Medica" records three kinds of best flames in the universe, the first is Lan Yan, which is also the most difficult to encounter, the second is True Flame, the third is Wind Flame, Xiao Zhen's True Flame can be described as one of the best flames in the universe, and it is the best for refining pills.

The fire part of "Materia Medica-Fire System" is much more than the content of the Materia Medica, Yuan Feng sorted out his thoughts, took a deep breath, and continued to comprehend the knowledge of the fire system, the alchemy furnace or alchemy tripod also has grades, compared to ordinary horcruxes, high-grade alchemy tripods are much more difficult to find, and the natal alchemy pill tripod of an immortal medicine sect elder like Wen Zhenghan is only at the level of a high-grade celestial weapon, but if it is such an alchemy tripod, if it is put at auction, the price will definitely not be lower than the price of a low-grade holy weapon.

Yuan Feng took out the alchemy tripod obtained from Fall Island, and under careful observation, the dragon pattern on the tripod body was clear and exquisite, and he could feel the breath from the ancient times under the gentle touch, I am afraid that this tripod is not only a top-grade celestial weapon level, Yuan Feng thought secretly, and continued to browse the introduction of the fire system exercises.

The fire system exercise method is the method and secret of alchemy to control the fire, but this kind of thing is useless just by looking at it, Yuan Feng decided to try it himself, according to the "Fire System - Materia Medica" Yuan Feng is ready to refine the lowest-level Earth Soul Pill, Yuan Feng does not dare to easily refine the Longevity Pill that can increase longevity, although there is Longyan Immortal Grass, True Spirit Water, and there is also a meditation grass in this secret room, but the first time it is from the lowest level of refining, the truth that you can't become a fat person after eating a meal Yuan Feng still understands, Yuan Feng took out the alchemy pill, called Xiao Zhen out, and selected six kinds of soul grass for refining the Earth Soul Pill in this secret room, ready to test it himself.

"Xiao Zhen, are you ready?" said Yuan Feng with his long sleeves rolled up and looked eager to try.

"Always be ready, boss, what are you doing here, boiling medicine?" Xiao Zhen had never seen anyone refining pills, and said confusedly with big round eyes.

"Alchemy, do you remember, listen to me and tell me to shout 'up' and you will set fire, 'receive' you will take back the True Flame, understand? Yuan Feng slowly added the six kinds of soul grass to the Alchemy Ding in an orderly manner in the order of refining the Earth Soul Pill.

Yuan Feng's soul power in his hand was concentrated, and he looked excited and ready to start refining his first furnace of elixir.

"From. Yuan Feng prepared everything, Xiao Zhen was still very obedient Hearing the boss's order, the extremely high temperature of the true flame immediately erupted from Xiao Zhen's mouth.

True Yan deserved to be the second flame in the world, Yuan Feng didn't control it well for a while, the fire instantly lingered around the Alchemy Ding, and those low-grade soul grasses were also burned into a ball.

"Failed? Yuan Feng was unwilling to fail like this, and continued to control the fire around the alchemy pill ding, wiping the sweat flowing from his cheeks and forehead, and kept injecting soul power.

"Close, Xiaozhen. Sensing the existence of a spherical object in the alchemy tripod, Yuan Feng immediately stopped refining.

"Xiao Zhen, catch it. Yuan Feng slowly tilted the small mouth of the alchemy pill ding, and the pills that were not round fell into Xiao Zhen's hands, and the refreshing medicinal fragrance immediately confused the entire secret room between the stones.

"Sixteen, seventeen, thirty-two. Yuan Feng counted a total of thirty-two pills, but when Yuan Feng picked one up and brought it to the tip of his nose, he found that it was not the breath of the Earth Soul Pill at all.

"This is not the Earth Soul Pill, is it the Qi Gathering Pill?" Yuan Feng already had a clear understanding of the type of Soul Pill, and once again leaned into the tip of his nose and found that the thirty-two black pills were most likely Qi Gathering Pills.

"There's no reason for that. Yuan Feng thought hard to no avail, so he simply put away the alchemy tripod and continued to take out the remaining unfinished "Fire System-Materia Medica".

"Yuan Feng, what's going on, are you refining the pill?" Wen Zhenghan was very sensitive to the medicinal fragrance, and the medicinal fragrance in the air had not yet dissipated in half an hour, and he looked at Yuan Feng in surprise.

"That's it, but it failed. Yuan Feng said ashamedly.

"No, this is the breath of the Qi Gathering Pill, are you practicing the Qi Gathering Pill?" Wen Zhenghan, as an old senior alchemist, is no stranger to the Qi Gathering Pill.

"Master, is this really the breath of the Qi Gathering Pill?" Yuan Feng respectfully handed several black freshly refined pills to Wen Zhenghan.

"How can you refine such a high-grade pill? Isn't this scientific?" Wen Zhenghan could feel that the pills exuded strong medicinal properties, and looked at Yuan Feng again.

"Originally, I was going to refine the Earth Soul Pill, but I didn't know that I had such a miracle when I first refined the pill. Yuan Feng didn't hide it.

"Hehe, your kid is also too lucky, if there are special conditions during the refining of the Earth Soul Pill, there will be a 1 in 1,000 probability of refining it into a high-grade Qi Gathering Pill. Although there is no record of this matter in "Fire System-Materia Medica", Wen Zhenghan, who is well-read and strong, remembers it very clearly, and immediately sighed with emotion.

"I see. Yuan Feng was relieved.

"Master, although these twenty Qi Gathering Pills are not very valuable, I ask Master to accept a piece of the disciple's heart. Yuan Feng took out twenty Qi Gathering Pills and respectfully handed them to Wen Zheng Handao.

"Since this is Yuan Feng's intention, Master will accept it first, I don't know how you have comprehended the "Fire System-Materia Medica" and "Dan Dao Foundation?" "As a high-level alchemist, it is not very difficult for Wen Zhenghan to refine such elixirs, but it takes half a month to refine a hundred Qi Gathering Pills according to the normal procedure, so Wen Zhenghan was not polite and accepted twenty high-grade Qi Gathering Pills.

"It's almost understood. Just before Wen Zhenghan came in, Yuan Feng had already reviewed the content of "Fire System-Materia Medica".
