Fire, an important factor in the progress of human society, is now in another form in front of Mojixuan.

In other stories, it is very simple for a monk to want fire, or to make a fire-type spell.

Like what Samadhi True Fire, what Nine Yin White Bone Fire, it almost comes as soon as you open your mouth.

In the era in which Ink Mark Xuan lived, fights between monks basically relied on the method of vigorously performing miracles.

Although he had successfully invented the Spirit Gathering Array with the help of the principle of bionics, he also improved the Spirit Gathering Array and used the lack of formation to make it a detonation device.

It's not easy to invent a fire-based spell.

In his previous life, the nine-year compulsory education had taught him that two things were needed for fire to form. Incendiary materials and oxygen are indispensable.

This knowledge has great limitations in the world of cultivation, for example, the samadhi true fire in his memory seems to be able to be released at the bottom of the sea.

In other words, the vast majority of fire-based spells in the Xiuzhen world were not real flames, but another form of energy.

If so, then it's easier to understand.

As a simple example, water has three forms in nature, gaseous water vapor, liquid water, and solid ice.

Among these three forms, water itself does not change, only the distance between molecules changes, thus showing different forms.

Thinking of this, Mo Jixuan couldn't help but stretch out his hand, and then released a trace of aura to gather in his hand. Then he used more aura to compress the aura released earlier, and then compressed it again.

The trace of aura in his palm was compressed by him, although it did not become solid, but it was more condensed.

Gradually, Ink Marks felt a burning heat coming from his hand, and then exploded with a pop.

This happened to startle Ink Marks, and he quickly looked back at the two guards, and found that the other was focused on eating meat, not noticing that he was coming.

He was relieved and immediately remembered what had just happened.

Reiki did not become solid under extreme compression, which should be that Reiki itself does not belong to the conventional substances in nature, and cannot be evaluated by high school chemistry.

It should be a much higher quality energy!

This discovery made Mo Jixuan couldn't help but smile bitterly, if he was now in the realm of returning to the void, and the explosion generated by the compressed aura, as long as a wisp of aura was injected into the opponent's body through various methods, the aura that suddenly exploded would definitely solve the current predicament.

But in his current realm, if he wants to use this trick to put the other party in, it is almost an impossible thing to complete.

So he simply gave up on this idea for the time being, and his mind returned to the fire spell.

At this time, it occurred to him that there is another property of flame - temperature.

As long as the temperature is high enough, it will burn up instantly if it touches something, and as long as the temperature is high enough, the object can even vaporize instantly.

And high temperatures, in addition to being made with flames, can be achieved by another method.

Friction!

He suddenly thought of the balls that Naruto often rubbed in Naruto's "Naruto" in his previous life.

As long as the trajectory of the aura is changed, that high-speed moving aura mass can create a terrifying high temperature!

Thinking of this, he could no longer be calm, and trace after trace of aura was released by him, and then controlled these aura to entangle with each other and quickly rub against each other.

Burst......

There was another faint light sound, and the aura mass in his hand suddenly dissipated.

The palm of his hand had been burned to a large patch of skin.

Ink Marks endured the severe pain, and found that this method simply did not work.

Even if he can rub out a large ball, the high temperature is not something that the mortal body can resist.

"Otherwise, I will use the aura that is about to explode as the core, and then detonate the kernel at the moment of excitation, and the unstable state formed by the explosion of the kernel will disrupt the orderly and high-speed rotating aura, thus causing high temperature, and will not hurt itself!"

After thinking about it again, he felt that this method could be used and was about to try it.

The sound of footsteps from far and near dispelled his thoughts.

It's the same giant from before!

He spoke to the two guards, and they retreated.

"I know you're awake, and you don't have to wonder why I didn't just kill you, but locked you up.

I can make an exchange with you, and if any of you can tell me the secret of the bone knife and longbow you used that day, I can consider letting you go. ”

His voice fell for a long time, and no one spoke.

However, he was not impatient, but continued: "We already know who you are, and your tribe is already gathering their people to come here to save you.

But we are ready for everything, as long as they dare to come. In this place, it is absolutely impossible for them to get out alive.

Think about it, do you want to keep the secret, or do you want the people of your tribe to give you a burial!"

When the words fell, Sui Zhong couldn't sit still first, he rose in anger, and his right hand quickly stretched out the wooden cage to grab the other party's neck.

The man tilted his head slightly, and then his right fist poked out, and the fists and palms intersected, and Sui Zhong's injuries were a few points worse.

Feeling the anger of the people in the prison, Ink Mark Xuan felt that this was an opportunity.

The other party's first purpose should be to master the secret methods of Ink Trace Xuan, and the matter of letting their tribe accompany them to the burial is just a bargaining chip.

This is a profoundly unequal negotiation.

Ink Mark Xuan thinks this is an opportunity!

Finally, he spoke: "I can tell you the secret method, and I can even make you five longbows, as long as you promise to let us go back!"

The man stretched out his hand and said, "Ten!"

Mo Jian Xuan hesitated for a moment, gritted his teeth and said, "Okay!"

"I want your explosive arrow and this!" he said, pulling out the bone thunder of Ink Marks.

"Don't think about this thing, it's not that I don't want to give it, but it's that refining this thing consumes too much, and the materials are relatively difficult to find. ”

The man waved his hand and said indifferently: "The material is not a problem, as long as you can make this thing for me, I can find you as many materials as possible." ”

Hearing this, Ink Mark Xuan fell silent.

The other man smiled and threw out his chips: "If you can make me twenty of these things, I will allow you to send a message." ”

"Well, I promise you, but you must let me see the tokens that my people have sent back to me, otherwise how will I know if you have kept your promises. ”

"Okay, that's fine!"

"What else do you need, just ask for a piece. ”

Mo Jian Xuan looked left and right and said, "I need a room, some meat." ”

The other party readily agreed, and then called the guards to release them from the wooden cage.

"I've done what I promised you, but you only have ten days. ”

Ink Marks nodded in clarity.

As he left with the guard, he turned to the man and asked, "By the way, what's your name?"

"Great Chief of the Southern Tribes, No!"

"I remember you!"
