The task was agreed, and Elder Yu took Gu Xuan into the dilapidated house, which turned out to be the so-called alchemy room.

There is a gap in the roof, and the floor is paved with green bricks, but there are potholes everywhere, and the height is uneven.

What's even more excessive is that on the side above the alchemy furnace in the center, which is a little exaggerated, there is a hole in the big pot of the fast pot, which is pasted by unknown materials.

Gu Xuan was stunned for a moment when he saw this environment, thinking of the uncommon and generous rewards, and he had a bad premonition.

As if seeing the doubts in his heart, Elder Yu grinned, "Elder Ben is experimenting with the new Dan prescription, and it is also very reasonable for the Danfang Dan furnace to break a little." ”

Hearing the new Danfang, Gu Xuan directly retreated in his heart.

"I'm sorry Elder Yu, the disciple's strength for this task is low, I'm afraid I can't do it."

Compared with the difference between a generous reward and a small life, Gu Xuan decisively chose to save his life.

After all, every alchemist was once a blasting ghost, let alone experimenting with the new Dan formula, and seeing the surrounding environment was not something that he, a little budding newcomer with a double qi, could withstand.

Elder Yu's brows furrowed suddenly.

He had been on this task for several days, and only then did he finally get a disciple, and he was about to retreat.

"On the basis of the original, how about I pay you another two hundred."

Plus two hundred rewards, that is seven hundred silver coins, and if the speed of receiving the task in the past is at least, it will take at least ten days and half a month.

Two days is ten days, half of the qi and blood soup is together, Gu Xuan's heartbeat is faster, and he still has no choice but to refuse.

Elder Yu ...... It's not about money. ”

"I don't think the money is enough, that's double!"

"Elder Yu, my strength is low......"

"It's so troublesome, you kid is too greedy, aren't you?" Elder Yu blew his beard and glared, and suddenly became a little dissatisfied.

"Ahem, Elder Yu, I'm a little afraid of death." Gu Xuan's eyes looked at the hole in the Dan furnace and chose to tell the truth.

Elder Yu was stunned for a moment, and finally understood what the kid in front of him was worried about, shook his head, took out a black wooden block from the drawer under the medicine table and threw it to him.

"Come on, it's really troublesome, I have a talisman card from the Refining Hall for you, if there is damage, it is enough to resist the impact of the Dan furnace a few times, not to mention that Elder Ben will still let you hang up!"

Under the guarantee of safety, Gu Xuan had no reason to refuse again.

Besides, he didn't want to miss out on such a big reward.

It's hard to make money.

Add water, build a stove, build a fire, throw medicine.

None of this was done by Gu Xuan.

Yu Danshi practiced first, and his technique was very capable.

But the source of alchemy fire is very strange.

As we all know, the cultivation world makes the most money than the three pillar industries of alchemy, talisman painting, and instrument making.

Naturally, there are extremely mature alchemy techniques that have flourished so far, and fire source is a very important vein in it.

Due to the limitations of the fire of the mortal world, if you want to refine a good pill, you must practice a fire technique, and refining it with the fire of magic is the most basic thing for an alchemist, and the fire of the mortal world is the work of the Dan disciples who have first come into contact with refining medicine.

Is this Elder Yu really a Dan Master who can refine pills?

Thinking of the introduction of the young lady in the green dress, Gu Xuan looked at the old man and felt faintly strange.

However, these are not things he needs to care about, and the use of mortal fire may be less dangerous.

Gu Xuan didn't think much about it, he did it step by step according to Elder Yu's action requirements, picked up the medicine and pounded the medicine, and added firewood to the bottom of the alchemy furnace at any time to pay attention to the heat.

Elder Yu leaned on a chair on the outer wall of the Dan furnace, stood above and looked at the position of the furnace mouth, and from time to time took a thick wooden stick to stir in it, during which he said the required steps to Gu Xuan from time to time.

In the blink of an eye, time passed, the sky gradually darkened, and the process of refining medicine had to continue.

It's really not easy to get this thousand silver dollars.

Gu Xuan added firewood at the bottom, found the medicine and handed the medicine, and the elders added medicinal materials and stirred it above.

The dilapidated alchemy room presents such a picture.

This kind of picture lasted for half an hour, and Elder Yu finally stopped moving in his hands, and then put a heavy copper lid on his hands.

It's really like boiling a pot and cooking a big pot of rice.

Gu Xuan slandered in his heart.

It's just that after the lid is covered, the remaining work is a little simpler, which is to stare at the fire below, and pay attention to the firewood to keep it from being extinguished.

Time passed, and on the way, Elder Yu took the time to open the lid, looked at it and didn't look again, walked to the door and looked at the wall panel and pretended to sleep.

The night was quiet, and soon there was a snoring sound.

Elder Yu slept happily, but he couldn't, and he had to pay attention to the heat according to Elder Yu's request, in case a sudden situation occurred.

On the way, Gu Xuan was bored and even a little sleepy, so he found an open space in the house and slowly rehearsed the movements of the Changchun Sutra.

Suddenly, he smelled the medicinal properties of the medicinal herbs escaping from the room, and it seemed that he could also inhale and increase his strength, and he immediately practiced more energetically.

I don't know how long it took, but he felt a slight heat in his abdomen, and the dantian of his body suddenly emptied.

Gu Xuan, who felt that he had lost something, opened the panel, and his potential increased a little again.

For such a long time, he gradually figured out the law of potential condensation, ate and drank, and could condense a little potential in an average of one and a half months before practicing Changchun menstruation.

After eating the Demon Beast Great Tonic Soup, the time to condense the potential was reduced by a bit, and the time for about twenty meals of the Demon Beast Great Tonic Soup was only about a month.

And after practicing the Changchun Health Sutra, it is different, perhaps because of the higher efficiency, the refining time of ten tons of demon beast tonic soup only takes seven or eight days.

As for the beggar's version of the rough and simplified version of the Qi and Blood Soup, in the past two months, Gu Xuan has only eaten the two flavors last time, and it is still used to eat most of the silver money used to eat the Demon Beast Tonic Soup, which is faster and more efficient, and it takes a little more to increase on average, and it takes two days to refine.

It seems that ten meals of demon beast tonic soup will cost five hundred silver dollars, and a beggar's version of qi and blood soup will cost one thousand and five, which is a bit of a loss, but the efficiency is not improved by a star and a half.

If it weren't for the lack of money, he really wanted to do it in two days.

Thinking of these miscellaneous things, Gu Xuan practiced the Changchun Sutra over and over again on the fire, and his qi and blood were endless.

Overnight, slowly passed.

The east was white, Gu Xuan had already stopped and rubbed his sleepy eyes, looked at the weakening fire, and threw a piece of firewood into his spirit.

Then, the Dan furnace made a muffled sound, and wisps of black smoke were fluffed......

Immediately after that, the furnace mouth exploded, and a shock wave hit, and a layer of light appeared on Gu Xuan's side, and the talisman card he had just gotten in his hand cracked with a click.

I said that I could resist it a few times.

How to put it all this very suddenly.

It happened so suddenly.

When Gu Xuan came back to his senses, he admired his foresight.

At this time, the smoke and dust in the room were scattered, and there was a mess around him, and Elder Yu didn't know when he woke up and sat in one place, with a large black iron pot on his head blankly.

"Hey, it's a little dark."

This......

Gu Xuan was stunned, has Elder Yu's sense of alchemy always been so strong?
