In the alchemy room of the Heavenly Sword Sect's Dan Dao Academy, the flames used for alchemy come from the earth fire, which is controlled by the earth fire hub of the entire Dan Dao Academy. There is no need for someone to manage the fire, so the disciples who guard the fire only need to keep it from happening and do nothing.

Ye Xuan found a book and read it while lying on the couch.

Three hours later, Wang Xuan'er hurriedly ran into the alchemy room and said, "Senior brother, I'm resting." ”

Ye Xuan got up and walked out, and said at the same time: "Then you watch, I'm going to rest." ”

"Okay, senior brother, go slowly. What do you call Senior Brother?" Wang Xuan'er asked with a bow.

"My surname is Ye. ”

"Okay, Senior Brother Ye. Wang Xuan'er continued to bow and watched Ye Xuan leave the alchemy room.

Midnight.

Ye Xuan was suddenly woken up, and then he heard a whining cry.

"What's wrong?" Ye Xuan frowned and stared at Wang Xuan'er, asking puzzled.

"Our furnace Tianyuan Dan is broken...... This time he is dead, and he will definitely be punished by the elders......" Wang Xuan'er said crying.

Ye Xuan pulled her out of the room and asked as he walked towards the alchemy room, "What the hell is going on?"

"I don't know, I smelled a little strange smell from the Dan furnace, so I was so anxious that I didn't know what to do, and finally secretly opened the Dan furnace to take a look, and the entire Tianyuan Dan was broken. Wang Xuan'er cried and said.

As soon as Ye Xuan entered the Tianzi No. 2 alchemy room, he smelled an abnormal medicinal smell, which was a bit unpleasant, and it was definitely not the medicinal fragrance emitted by Tianyuan Pill.

"What to do...... This time it's a dead end......" Wang Xuan'er was so frightened that she turned around.

Ye Xuan opened the Dan Furnace and took a look, and found that the entire Tianyuan Pill was emitting an unpleasant smell and had been scrapped.

Ye Xuan carefully identified these Tianyuan Dan and immediately knew what was going on.

"When you looked at the fire, didn't you leave a single step?"

Wang Xuan'er immediately shook her head: "No, I don't dare to leave a single step." ”

"Are you sure?"

"I'm sure I never left. Wang Xuan'er said very firmly.

"Has anyone else come in?" Ye Xuan asked again.

"No......" Wang Xuan'er just wanted to say no, but then she thought of something and changed her words, "Senior Brother Yu has been here once." ”

"Yu Mingming?" Ye Xuan frowned and asked, "What is he doing here?"

"It's nothing, it's just to check the elixir materials used in alchemy. Wang Xuan'er replied in recollection, and then said with a bitter face, "Senior Brother Ye, what should we do now? This furnace Tianyuan Dan is for the disciples of the Imperial Sword Pavilion, if we let the elders know that the Tianyuan Dan refining has failed, we will die." ”

"Tell the elders to re-refine the furnace. Ye Xuan said.

Wang Xuan'er hurriedly shook her head: "It's too late, the Imperial Sword Pavilion will want this batch of Tianyuan Pills after dawn, and if we can't take it out by then, the elders will definitely punish us to fertilize the elixir field...... I don't want to pick the feces of spirit beasts......"

The Heavenly Sword Sect's Dan Dao Academy has its own elixir field, and most of the demon beast feces cleaned up by the Spirit Beast Courtyard are used to fatten the elixir field.

Ye Xuan frowned and thought for a moment, and asked, "Are there any other elixir materials?"

"There's still a little left, but what's the use?" Wang Xuan'er took out the remaining elixir materials.

Ye Xuan glanced at it and said, "It's not enough, can you find some more?"

"There should be some leftover from the other alchemy rooms, I'll go and beg the other senior brothers to bring some. Wang Xuan'er said, and immediately ran out of the alchemy room, went to ask the fellow door of the other alchemy rooms, and asked for the remaining elixir materials.

Since the elixir materials required for alchemy, according to the situation at the time, the dosage will be more or less, so when distributing the elixir materials, there will be a surplus.

These remaining elixir materials, according to the rules, must be returned to the elixir warehouse in the end.

However, occasionally, if a certain alchemy room consumes more spiritual medicine materials than the quota due to problems such as alchemy techniques, it will also misappropriate some from other alchemy rooms.

Therefore, the supervision of this part of the Dandao Institute is not strict.

Soon, Wang Xuan'er asked for a batch of elixir materials from other alchemy rooms.

Ye Xuan glanced at it and saw that the amount was almost enough, so he rolled up his sleeves and prepared to dry.

"Senior brother, what do you want to do?" asked Wang Xuan'er suspiciously.

"Alchemy. Ye Xuan said as a matter of course.

Wang Xuan'er frowned and asked, "Senior Brother Ye, can you refine the Tianyuan Pill?"

"Yes. ”

Of course, Ye Xuan would refine the Tianyuan Pill, but he had never refined it.

Wang Xuan'er felt very strange, and frowned.

The Dan Dao Academy's refining of the elixir is for the Dan Dao elders or disciples who are qualified to refine the elixir first, and then continue to refine it through the earth fire.

In the Dan Dao Academy, there are very few disciples who are qualified for alchemy.

The disciples who know how to alchemy, they are all high-ranking existences, and they will never be arranged to guard the furnace fire.

Ye Xuan ignored Wang Xuan'er's puzzled eyes, threw away the waste pill in the Dan furnace, and then began to refine the Dan.

Tian Yuan Dan is a second-order pill, and the difficulty of refining is much greater than that of a first-order Qi Condensing Pill, but for Ye Xuan, who has the inheritance of the Dan Emperor, there is actually not much difference.

Ye Xuan threw all the spiritual herbs into the Dan furnace, and then released the Black Flame Fire, ran the fire control technique "Heavenly Fire Dao", and began to refine the Tianyuan Pill.

The alchemy method of the Heavenly Sword Sect Dan Dao Academy is to refine in large quantities, and one furnace of Tianyuan Dan is ninety-nine eighty-one.

This method of batch refining is different from the method of refining individually.

Refining them individually can respond to various changes in the refining process of pills, making it easier to produce high-quality pills.

And batch refining, it is difficult to produce high quality.

Despite this, under the control of Ye Xuan's fire control technique, the refining process was much smoother than that of simple earth fire refining.

Wang Xuan'er had been watching from the side, her face full of surprise and doubt.

She felt that Ye Xuan should not be able to refine the pill, but she prayed that Ye Xuan could refine the Tian Yuan Dan so that he would not be punished.

An hour later, the alchemy was completed.

Ye Xuan checked the refined Tian Yuan Dan, nodded and said, "Okay, tomorrow when they come to get the Tian Yuan Dan, you will give the Tian Yuan Dan to them." ”

"This ...... Is this good?" Wang Xuan'er asked incredulously with round eyes.

Dan Dao Academy's refining of Tianyuan Dan is to refine for three days and three nights.

But Ye Xuan had only been refining for an hour, and he said that he had finished refining, how could this not be surprising.

"Okay, just give them the pill tomorrow. ”

Ye Xuan didn't explain much, his alchemy used the supreme fire control technique of the Seven Peerless Dan Emperors, which was naturally thousands of times stronger than the earth fire refining.

The next day.

Yu Mingliang brought someone to fetch the Tianyuan Dan: "Wang Xuan'er, has the Tianyuan Dan of the Tianzi No. 2 furnace been refined?"

"Good...... Okay......" Wang Xuan'er handed over a large jade box in a bit of a panic.

Yu Mingliang saw Wang Xuan'er's panicked expression, and immediately counted it in his heart, and directly took the jade box and handed it to the disciples of the Imperial Sword Pavilion who came to pick up the Tianyuan Dan.
