The so-called combustibles are similar to the stoves used for heating in Huaxia, and there are many types of combustibles, including coal, and charcoal that is more resistant to burning in the cultivation world.

There are pros and cons to both methods.

The disadvantages of the first method are undoubtedly significant, the requirements for the depth of the cultivator's spiritual power and spiritual power are too high, and if the cultivator does not have two brushes, he will not be able to control it at all. I'm afraid that before the first furnace of elixir is finished, it will be directly squeezed dry and die.

As for the benefits of the second method, it happens to make up for the nose end of the first method.

Relying on combustibles can reduce the consumption of cultivators' natal flames, and save spiritual power and spiritual power to refine pills.

However, for alchemists, this second method has a fatal drawback, that is, it is difficult to control the heat, and because the heat is not well controlled, it is basically impossible to refine high-grade things by relying on combustibles to refine medicines and refining weapons.

Well, these two methods really complement each other!

After figuring out this, Situ Luo suddenly felt that he was speechless.

Speaking of which, if she wants to seek the long term, she must rely on the first method of refining weapons and medicines.

Although the second type does not require high spiritual power and spiritual power, it cannot refine good things.

What is the difference between alchemists and refiners who don't want to refine good things and salted fish?

"However, the biggest problem at the moment is that I don't have a natal flame!" Although he had already decided to take that path, Situ Luo still didn't get happy.

There's no natal flame, and it's a ball of yarn!

Scratching his head, Situ Luo suddenly had a headache. Closing the refining notebook, she rubbed her chin and muttered, "Where are you going to get the natal flame?"

Then she smiled helplessly: "So, I can only refine the weapon through the second method first, and when I find a way to get the natal flame, I will change my habits!"

Thinking of doing so, Situ Luo suddenly put away the Ding Furnace and the refining notes at the same time, and when she opened the door, she was about to go outside to take a look and see where there was a place to sell coal for refining.

It just so happened that Baili Qingzhu and Tao Yunan were about to go out at night, and when they saw Situ Luo coming out, Baili Qingzhu smiled suddenly: "Brother Luo, do you want to go out?"

Situ Luo suddenly nodded: "I want to buy some carbon!"

"Buy charcoal?"

Baili Qingzhu was stunned, and Tao Yunan glanced at the sun that had sunk in the west outside, and he was also speechless.

Situ Luo thought about it for a while, it didn't hurt to say this kind of thing, she could also probe the tone of Baili Qingzhu by the way, and ask him if he knew how to get the natal flame, so she said truthfully: "I want to learn the refining weapon, but I don't have the natal flame, so I want to replace the natal flame with coal first." ”

"Forehead......" Baili Qingzhu became more and more surprised, and Tao Yunan looked at Situ Luofei with the eyes of an idiot in his clothes, and Situ Luofei was inexplicable.

"Is there anything wrong with what I said?"

"Brother Luo......"

Baili Qingzhu smiled strangely and asked rhetorically, "Don't you have a contract beast that can breathe fire?"

Situ Luo nodded suddenly: "Xiao Hei is indeed my contract beast, but I can't use its flames!"

Baili Qingzhu was surprised again, he and Tao Yunan glanced at each other, and then said in disbelief: "That's not your natal contract beast?"

"Natal ...... Contract?" Situ Luo suddenly looked dazed.
