"Crunch!"

Half an hour passed, and at this time, the gate of the Danlou was at the gate, and I saw Ding Wen walking out with the four mentors of the Alchemy Guild with a triumphant look.

"Qianyi, why are you here?" Ning Sanhe, who had always been serious, became pampered when he saw Qianyi.

"Grandpa Ning, Grandpa Zhang, Grandpa Sun, Grandpa Ziyang!" Qianyi exclaimed one by one with a slight smile.

"Qianyi, is she the youngest third-grade alchemist in the Medicine Refining Guild?" When Ding Wen saw Qianyi, he was completely attracted by her beauty, and at the same time heard of her name.

"I want to refine a Heavenly Bone Qi Pill!" Qian Yi said.

"Okay, but you'll have to wait a while!" Zhang Shouyin touched Qianyi's head, looking very fond.

"Ao Lingtian, it's your turn!"

Ao Lingtian nodded, and then followed the four of them into the Dan Tower, but not on the first floor, but on the second floor.

When Ao Ling Tian went up to the second floor, he also took a look, because he saw that there were medicinal materials for refining the second grade pill everywhere here.

"Ao Lingtian, you must refine a second-grade pill prescription to prove that you already have the strength of a second-grade medicine refiner, as for what pill, you can choose!" said the old man Ziyang.

"I don't have time to take the first-level exam, so it's better to be more direct!" Ao Lingtian looked at the four of them in the Medicine Refining Guild, a smile rose at the corner of his mouth, and then the black qi refining fire in his hand gushed out, and said, "I want to test the level of the medicine refiner, the fourth-grade medicine refiner!"

"Fourth-grade medicine refiner?" Zhang Shouyin suddenly glanced at the other three in surprise when he heard this.

"Ao Lingtian, are you telling this?" Ning Sanhe asked with a serious face.

"You really already have the level of a fourth-grade medicine refiner now?" Sun Mu said with a shocked expression.

"Do you think it's strange to have the strongest Qi Refining Fire in Heaven and Earth, and you are already a fourth-grade medicine refiner?" Ao Ling Tian said lightly.

However, when the four of them heard this, they were indeed speechless, because they also knew that those who possessed the fire of refining qi would not be of a low level.

Soon, the four of them couldn't believe Ao Lingtian, because Ao Lingtian was just a hairy kid in their eyes, but they also had no reason to doubt it, so they directly took Ao Lingtian to the fourth floor of the Dan Building.

"Even we can't come up on the fourth floor, but you have to take the fourth-grade medicine refiner, so we broke the rules to come up, if you lie to a few of us, the consequences will be very serious!" Ning Sanhe said in a low voice.

"Just look at it!"

Ao Ling Tian only smiled indifferently at his warning, and then went to the side to select medicinal materials to refine the elixir.

"It's worthy of the Medicine Refining Guild, and the medicinal materials that are hard to find are all here!" Ao Lingtian saw the medicinal materials here, and he had the idea of wanting to put them in his pocket, but he didn't know if he would scold himself to death if the four of them knew about it.

"Black chrysanthemum venom?" Ao Lingtian suddenly saw more than a dozen black vials lined up in one place, and the words Black Chrysanthemum Venom were written on the outside of the bottle.

"The medicinal materials here are all medicinal materials that can refine the four-grade pill, what pill you want to refine, just choose!" said the old man Ziyang softly, with expectation in his eyes.

"There is actually black chrysanthemum venom, then refine the ghost pill to have fun!" Ao Lingtian said secretly in his heart, took a bottle of black chrysanthemum venom, and then walked towards other medicinal materials.

After a long time, he chose six kinds of medicinal herbs, black chrysanthemum venom, nine-tailed corpse grass, cuiyunzi, large-fruited golden silk flower, lotus seed heart, and seven-leaf lotus.

When the four of them saw the selection of such medicinal materials, they glanced at each other and seemed to be a little stunned.

"Can you tell us what elixir you want to refine?" Zhang Shouyin asked curiously.

"You'll find out later!"

"Boom!"

After Ao Lingtian responded casually, he took out his alchemy furnace in the ring, and with a bang, a seemingly ancient alchemy furnace appeared in front of several of them.

"This alchemy furnace actually exudes a mysterious and powerful aura!" Seeing this, Sun Mu's old face was full of surprise.

"It looks old and obscure, but it's definitely not an ordinary thing!" Zhang Shouyin stared at the alchemy furnace that appeared in front of him.

"What is the origin of this arrogant sky? not only does he have the fire of refining qi, but he also has such an extraordinary alchemy furnace. The old man Ziyang's calm tone was unbelievable.

"You seem to have forgotten that he said that he was a fourth-grade medicine refiner!" Ning Sanhe looked at Ao Ling Tian with a solemn face.

"Bear!"

The arrogant Qi Refining Fire suddenly emerged, burning under the alchemy furnace, and the heat of the Qi Refining Fire made the temperature of the entire fourth floor extremely high.

After a long time, Ao Lingtian put the Nine-Tailed Corpse Grass into the alchemy furnace for refining, followed by Cuiyunzi into the Dan furnace for refining, and his hands quickly carried the seal of the fire of qi refining.

"Condensation!"

A low cry came out, and the two medicinal herbs of Nine-Tailed Corpse Grass and Cuiyunzi condensed together and turned into a black liquid.

"Bear!"

Seeing this, the Qi Refining Fire in his hand immediately increased to about eighty percent, and this time the Seven Leaf Lotus and the Lotus Seed Heart were refined at the same time.

When the two medicinal materials were inserted, Ao Lingtian's face was a little more serious than before, and the Qi Refining Fire was also controlled very accurately.

"This alchemy technique is really eye-opening!" Seeing this, Ning Sanhe looked full of admiration on his face at this time.

"I have to admire!" the other three nodded at the same time in agreement with what Ning Sanhe said.

"Condense into one!"

Ao Lingtian quickly pinched the seal with both hands, and his heart burst into a loud shout, and his hands seemed to be mysterious.

However, when he pinched the seal, all the medicinal materials of the alchemy furnace were condensed together, but they were all refined into black.

At this time, the Great Fruit Golden Silk Flower was put into the alchemy furnace by Ao Ling Tian, but his Qi refining fire dropped to about fifty percent, and the Great Fruit Golden Silk Flower slowly melted in the alchemy furnace and condensed with other medicinal materials.

After Ao Lingtian saw that these five medicinal materials had melted and condensed together, the corners of his mouth couldn't help but raise a slight smile, and then he picked up the black chrysanthemum venom in his left hand and poured it into the alchemy furnace.

"Snort!"

The black chrysanthemum venom poured down, like water dripping on a fire, and snorts came from the alchemy furnace.

"Condense into Dan!"

The Qi Refining Fire in Ao Ling Tian's hands instantly converged, but his hands were quickly pinching the seal, and the medicinal materials that had been refined in the alchemy furnace were condensing into Dan.

After a while, a black pill the size of a thumb slowly rose into the air in the alchemy furnace, and this elixir did not smell at all, but the luster was very bright.

"Can the four seniors know this elixir?" Ao Lingtian put away the alchemy furnace and brought the black elixir to the four of them.

"What kind of elixir is this?" Sun Mu took his hand and looked at it carefully, not only did he not smell the medicine, but he didn't smell anything.
