The word "true fire" is a Taoist term, according to Hu Fuchen's "Dictionary of Chinese Taoism": "true fire" refers to

"The fire of the true god, the fire of the invisible god, the fire of the innate god. According to Neidan, the visible fire is the ordinary fire, such as the fire of a candle and the fire of knowing God; The invisible fire is the real fire, such as the innate divine fire contained in the unlit candle, and the fire contained in the primordial god. The difference between the two is that mortal fire is an acquired fire with a limited form, while true fire is an innate fire that is invisible and infinite. Where fire hurts the body, the real fire gives birth to the gods. But fire and true fire are not two things. The relationship between the two is like the potential of the fire when the candle is not lit and the reality of the fire when it is burned, which is inseparable. Practitioners should cultivate true fire and not turn it into ordinary fire. According to this, the meaning of true fire in Neidanology can be simply understood as:

"Formless and non-visible energy", on the one hand, it is different from the tangible mortal fire, and on the other hand, it is the premise for the formation of tangible fire.

The big apprentice has a hot personality, a Miao knife is played with a big open and closed, and there is a tendency to look at it, according to Daozang's original intention is to let the big apprentice learn the gun, how can she like Miao Dao, Daozang also let him go.

When refining Tang Minghuang's Miao Knife, Daozang only put a lot of effort into the three aspects of solidity, toughness, and sharpness, after all, Tang Minghuang had a certain foundation in martial arts, and he was also very experienced in fighting with people.

But since it was a refining weapon, if there was no magic use, Daozang was also very unwilling, so he could only engrave a gravity formation on the body of the knife.

When the big apprentice needs it, the weight of that Miao knife can be increased by a hundred times, and if the enemy is not careful, he will suffer a big loss.

The anti-gravity phenomenon of this space island has been being studied, the research of modern science has not been ideal, and the research of Taoism has made some breakthroughs.

Daozang's headache is the weapon of his little apprentice Erya, because Erya is relatively young, Daozang only taught some small hand skills, and the rest of the body refining exercises are afraid of affecting the child's development, Daozang is the same is not taught.

But now the child sees that the senior sister has a weapon, and he is also arguing with Daozang to ask for it, how can this master have a bowl of water!

Originally, it was over by refining a sword directly according to Daozang's intentions, but I also know that when children now love beauty, they will never be satisfied if they don't have new tricks.

There was no way, Daozang could only refine a pair of odd-shaped weapons, and after thinking about it, Daozang decided to refine a pair of Emei thorns.

Emei Thorn, one of the martial arts instruments of the Republic. Emei thorn appeared as a martial arts item at the end of the Ming Dynasty.

The Emei thorn used in martial arts is about 30 centimeters long, its shape is a thick middle, two thin cones, the head is slightly flattened, diamond-shaped with a point, there is a ring in the middle, the ring is set on the practitioner's middle finger, the left and right hands each hold 1, use the wrist shake and fingers to pluck to make it rotate.

Running the mana eyes, mouth, and nose spewed out real fire, and the flames enveloped the meteorite in the air, and the meteorite Sumeru softened, and then changed according to the shape of the Emei thorn.

After the foundation of the Daozang is built, you can use the true fire, but it consumes a lot at the beginning, and it is only recently that it is used to refine the weapon after it has been stabilized.

At the moment when the Emei thorn was about to take shape, Daozang quickly smashed a phantom formation into it.

In this way, when you fight with people in the future, as long as you run the mana, there will be a lot of Emei thorns, giving people a dazzling feeling.

Of course, these are not worth mentioning in front of real masters, but they are beautiful! It should be able to meet the requirements of girls of Erya's age.

When Daozang was refining weapons for his apprentices, the entire Demon Slayer Alliance also mobilized to find out what the Jiao Demon King had fallen into.

After inviting all the people who could be invited, there was still no progress in the matter, and I only knew that there might be a problem with the soul, but I didn't have a clue what the problem was and how to heal it.

Ten days have passed, and the Jiao Demon King was still awake for a while at the beginning, but now he is basically in a coma all day.

The temper of the demon emperor is very bad these days, it's not because of how angry a demon king is, it's just that everyone is helpless about this situation, and they can't even understand the basic reasons, so they are very frightened, what if the target this time is not the Jiao Demon King but himself?

When the Demon Emperor was irritable, and even a little frightened, Niu Qianmo's summons finally arrived.

After reading the interrogation, the Demon Emperor took the case on the spot: "Sure enough, it's them, these alien humans actually attacked my demon clan for no reason, I'll go and meet them." Only then did the black and white match see clearly, this demon emperor turned out to be a woman, wearing a big red robe and wrapping herself tightly, if it wasn't for getting up too fast just now, the hood on his head slipped off, and he couldn't see his appearance clearly.

Usually the Demon Emperor only speaks with his mind, so that people can't distinguish between men and women, just now it was the first time that the black and white pair heard this Demon Emperor open his mouth.

Of course, these mental activities are only over in a moment, and the black and white duo quickly bowed their heads, and now is not the time for them to interject.

"The Demon Emperor's words are wrong, how can it be for no reason? If this Jiao demon hadn't broken out and hurt people, it wouldn't have had such a bad result, so it's just to blame. "How could the great power of the human race let the demon king go to the trouble of the human race, in addition to the high-end combat power for so many years, the human race has always been at a loss, and now it is finally up to a group of human beings to not sell the face of the demon race, and it is too late for this great power to be happy.

Seeing that the old guy of the human race blocked it, the demon emperor did not continue to insist, anyway, there will be opportunities in the future, and there is no need to tear his face with the human race here.

You must figure out what this is going on, otherwise you won't be ridden on top of your head by the Terrans in the future?

Of course, Daozang didn't know that he had been remembered by a female goblin, and at this time, Daozang finished worshipping at the altar as usual, and then began to daze at the two large meteorites.

The Emei thorn that was refined last time has been given to the little apprentice, and I really like it very much, and it is time to refine a few magic swords for myself after this little trouble.

These two meteorites, one was ejected during the eruption of the Northeast volcano, and I don't know how many years it has been refined in the volcano, and it has all turned purple.

One piece was found by the mountaineering team on the world's highest peak, and it is not known how many years it has been buried in the ice and snow, and the original color is no longer visible, and it is all cyan.

These are two treasures, and the reason why Daozang can't pay attention to them is because Daozang wants to refine them independently.

Although this is a bit overkill, it is not the best choice at this stage, but the benefits are also obvious, and you can continue to use it after your own cultivation is greatly improved in the future.

True fire gushed out, two meteorites flew in the air, slowly melting, this time it was very different from the previous one, these two meteorites had almost no impurities, so it was also very difficult to condense, if it wasn't for Daozang's full preparation, he would definitely give up halfway.

When the two magic swords were about to take shape, Daozang put the prepared phantom array and gravity array, two formations that he had experienced, into the two magic swords in turn.

When it was time to put away his hands and shape, Daozang had an idea, and he also described the feelings of the steps under the altar these days on the two magic swords.

But there are too many contents at one time, and a magic sword can't be carved, there is no way, Daozang can only engrave the upper half and the lower half one by one.

After the depiction is completed, it is the final shaping, and these Daozang have plans, just follow what you think in your heart.

When the two magic swords finally took shape, the sky was suddenly covered with dark clouds, lightning and thunder, and the two magic swords flew into the sky without the control of Daozang, and a thunder sounded, and several lightning bolts slashed at the two magic swords flying in the air.

Daozang was surprised at that time, it was not that this phenomenon scared Daozang, but that he was just refining two magic swords, this phenomenon was obviously the rhythm of a magic weapon about to be born!

After the surprise, Daozang was worried for a while, afraid that his magic sword would not be able to withstand the test of Tianwei, and finally the sword would be ruined.

Maybe those two meteorites are really old enough! The last two magic swords were not destroyed after being struck by lightning, but instead glowed, and finally flew around the sky and hovered in front of Daozang
