"Sister Yan, there is something I don't quite understand. Pen %Fun %Pavilion www.biquge.info"

Seeing that he was about to start refining medicine, he was curiously touching up and down, looking at Mo Bai who was scanning the medicine tripod, but he was puzzled.

"Huh?"

"Why do you have to use a Dou Qi flame to refine medicine, since there is a special medicine tripod, can't you also achieve the same effect by adding firewood to the bottom?"

Mo Bai frowned slightly, tapped the medicine tripod lightly as he spoke, and then put his ear on it to listen to the echo.

"Alchemy is not as simple as you think. It is a fact that the boiling point of the liquid is different, and the temperature at which the medicinal properties of various medicinal materials are refined is also different, some medicinal materials, such as the 'fangs of the ice snake', need a flame temperature of up to 900 degrees before they begin to melt, and some medicinal materials, if you heat it a little, they will turn into ashes......"

Yan Ruyu said that her beautiful eyes moved slightly, and the orchid finger poked out, and pulled out a sky-blue pig's trotter-shaped leaf from a row of medicinal herbs floating in the air.

"Just like this drunken incense leaf, it can only be heated to 30 degrees at most before the medicinal properties will be refined, but if you exceed this temperature, the medicinal properties will be evaporated in an instant, and the herb will be invalid at once. ”

"Speaking of which, I have to tell you that normal flames, burning in the air, have a temperature of nearly 500 degrees at the lowest visible red flame, and a terrifying white flame at the highest level. But the Dou Qi flame is different, and the temperature can be changed at will according to the master's will, so ordinary flames must not be used to refine the elixir. ”

"I see, I see. ”

Mo Bai suddenly realized, walked to the front of the Ding furnace, took a deep breath, and in his clear inky black eyes, "Then, let's start......"

"To refine the medicinal properties of high-melting point medicinal materials, there is no difficulty, you just need to desperately raise the temperature. And the best way to practice the flame control ability is to first refine the medicinal materials with a low melting point, and it is not easy to control the temperature of the Dou Qi flame very low, but as long as you can practice the low temperature well, I can tell you for sure that refining medicine will be easy for you in the future. ”

Yan Ruyu said with a smile.

"Really?"

Hearing the word easy, Mo Bai didn't believe it very much.

"Of course, it's not easy to do that. ”

Yan Ruyu pursed her lips and said, "Okay, it's useless to talk more, only if you really do it will you understand the difficulties, let's start, the first medicinal herb you want to refine is the orchid heart fruit with a melting point of seventy-eight degrees." ”

"Mr. Huo, Wen Ding for ten minutes, during which he first tried to raise and lower the temperature of the Dou Qi flame. ”

According to Yan Ruyu's instructions, Mo Bai immediately placed his hands on the two fire mouths, and subconsciously instilled the fire fighting qi into it, and in the next moment, the magic patterns on the entire Ding furnace lit up with dazzling red light, and with a bang, the inner wall of the entire Ding furnace was lit up with raging flames.

When Fang was trying the Ding in the Alchemy Guild, the old man who sold the Ding told him all the doorways contained in the Ding Furnace, these two fire ports are closed, in fact, they do not directly lead to the inside of the Ding Furnace, and their effect is only used to absorb the alchemist's flame fighting qi, and then after the separation, transformation and amplification inside the fire mouth device, it burns through the magic patterns on the wall of the Ding Furnace.

As the time passed, the flames ignited in the Ding furnace illuminated the entire dim underground cultivation room, and as the air gradually warmed up, Mo Bai's forehead soon became sweaty, only to feel a burst of stuffiness, and his breathing became short.

"The space here is too closed, the air is not circulated, and now there is a fire, and the oxygen is burned out, and if it continues like this, it will kill people. ”

It wasn't until he noticed that his chest was suffocating for a while, and Mo Bai, who was a little dizzy, suddenly realized this problem, and immediately decisively withdrew his fighting spirit.

The flames disappeared, and the underground cultivation room darkened again in an instant, looking at Mo Bai, who was panting and sweating profusely, Yan Ruyu's face showed puzzlement: "Why did it stop?"

Mo Bai glanced at her angrily: "Make a fire here, burn out the oxygen, and it will kill people." ”

"Oxygen ...... Angry, what is that?" Hearing this, Yan Ruyu fluttered her charming big eyes like a curious baby, and her face was confused, expressing her puzzlement.

"I told you don't understand. ”

There is no reason to talk to this uneducated woman, Mo Bai rolled his eyes, "No, I have to go out to breathe, in short, I can't refine medicine in this place in the future." ”

So, half an hour later, Mo Bai took the potatoes to the old place on the back mountain, next to the waterfall.

Under the poignant moonlight, the silver light reflected in the deep pool of the waterfall, swaying with the ripples on the water surface, flickering, illuminating the young man and his giant tripod on the side.

"Sister Yan, wrap me with your sixth sense, don't let anyone find me. ”

Turning his head to Yan Ruyu on the side, Mo Bai's face was solemn, he immediately took a deep breath, poured his fighting qi into the Ding Furnace, and in the next moment, a raging flame was once again ignited in the Ding Furnace.

"Don't worry, with me here, no one will bother you. ”

Looking at the young man who quickly entered the state, Yan Ruyu's delicate body moved, and flew up to the sky lightly, the water waves in her beautiful eyes flowed, as if she was patrolling, indifferently overlooking this dark mountain.

With the huge full moon as the background, the graceful and feminine figure rises and falls in the sky, with a different style, such as beautiful......
