At the bottom of the whirlpool due south, there were still dense patterns carved with patterns, which made Ye Yifei marvel at the same time, he woke up suddenly, and suddenly remembered the carved patterns at the bottom of the whirlpool due east just now.

"Shhh Because the carvings there are the same as those on the outside of the black dragon's body, "it seems that this is the test of the fire qi." Just because in this whirlpool, every martial artist was wrapped in fiery red mist, and as soon as everyone sat down, a fiery red mist directly drilled into everyone's sea of consciousness.

A fiery dragon groan instantly shook in Ye Yifei's sea of knowledge, making his face full of shock.

I saw a behemoth covered in flames, appearing in front of Ye Yifei's soul body, with a sinuous body, thousands of meters long, like a giant snake, the whole body hovered there in a circle, holding its head high, with a pair of slender horns growing on it, extremely beautiful, and a long dragon whisker on both sides of the wide mouth.

The whole body of fiery red oval scales, still carved with a dense layer of veins on the outside of the scales, forming a special pattern, very gorgeous and dazzling, and this pattern is completely different from the dark dragon's, almost nothing similar, but exactly the same as the carving at the bottom of this vortex.

The crystal clear eyes, like red gems, stared at Ye Yifei, and instantly opened his huge mouth.

A dragon groan full of fiery aura made Ye Yifei feel a strong burning sensation rushing towards him.

A surging flame erupted violently from the dragon's mouth, directly enveloping Ye Yifei's soul body, a strong sense of explosion, instantly making Ye Yifei feel that his soul body was about to explode at any time, and at the same time, it was accompanied by an extremely high temperature, making him feel as if he was being melted.

"Boom! Fierce explosion, intense incineration, worthy of the fire gas dragon." This time, Ye Yifei was very calm, the divine soul that had already been calcined twice by the Three Flavors True Fire, could he not be calm?

At this moment, Ye Yifei's soul body has already had an extremely high resistance to the high temperature of the flames, although the temperature of the flames spewed by the dragon is extremely high, but it can't make Ye Yifei feel too much pressure, only that strong sense of explosion is what Ye Yifei needs to seriously experience.

Why does the breath of fire send out such a powerful blast?

This starts with the temperature of the fire breath.

As we all know, the higher the temperature, the faster and more active the movement of molecules within an object, and vice versa, the slower and more silent.

For example, water turns into water vapor when heated, and steel melts when heated, and these physical changes are actually caused by the speed of molecular movement inside the substance.

At room temperature, there is a force between the molecules of each substance, which attracts each other to make these molecules form a stable state, the greater the force, the more stable the form, for example, the force inside the solid substance is much greater than the force inside the liquid, and the force of the liquid is much greater than that of the gas.

If these substances are heated, then the molecules will move faster, causing the molecules to break free from the binding force between the molecules, so that each molecule runs its own way, and no one can attract anyone, then the physical form changes.

If it's a gas, everyone is running separately and is completely dispersed, so the molecules run faster, and it's still just gas.

In addition to the forces between molecules, the atoms inside the molecules also have mutual forces.

If the temperature rises to a certain level, the atoms in the molecule will move faster, until the internal force of the molecule is broken, so that the atoms are completely separated, and finally the structure of the molecule is broken, and the substance is completely incinerated.

As for those atomic substances, they will not melt at all, because they are a molecule as a whole, and as long as the temperature reaches a certain level, the bonds between the atoms are broken, and they will also become a pile of white ash.

The temperature is completely brought by the fire gas, when studying the basic operation diagram of the fire gas, we know that the energy ball of the fire gas is the most active, and the running route is also the most tortuous, whenever the time ripple fluctuates, the energy ball will run along the triangular route, which leads to the maximum kinetic energy carried by the fire gas.

When the flame burns the object, the extremely active fire gas, when it encounters a stable object molecule, it will hit it violently, like playing billiards, it will first transfer its own kinetic energy to the molecules of the substance, so that the molecules have enough kinetic energy, and they will also begin to move faster, then the movement of the molecules will slowly become more and more active, which will cause the temperature of the object to become higher and higher.

This process is actually the essential reason why the object is constantly heating up, and when the molecular movement reaches a certain level, it slowly begins to melt.

With the increase in the temperature of the flame, the fire gas runs more and more intensely, although the molecules of the substance are extremely active, but it is still far from being able to keep up with the rhythm of the fire gas, then the conflict is generated, the fire gas violently impacts up, and these molecules are savagely rushed away, so that they are instantly torn apart, and the active molecules are completely **** out in all directions, so the explosion occurs.

This is the reason why when the temperature reaches a certain level, there will be a strong blast, when the space is compressed, the more intense the collision will be, and the more powerful the blast will be.

Through continuous comprehension, Ye Yifei's comprehension of the fire qi in his mind became clearer and clearer, and the corners of his mouth slowly showed a smile.

"Haha...... In this way, the characteristic of the fire qi is actually to continuously improve its own movement energy, so that its own energy becomes more and more violent, then in addition to the extremely high temperature, the explosion will be extremely fierce and powerful, no matter what object it encounters, it will strongly shatter everything, this is a barbaric and fierce way of destruction, and it belongs to the true meaning of the destruction of fire qi."

At this moment, by perceiving the phenomena in life, Ye Yifei found the true meaning of destruction exclusive to the fire qi, and instantly made his understanding of the fire qi reach an extremely high level.

At this moment, under the southern whirlpool, there are still as many as a few people, except for the four people last time, this time Li Yuer actually insisted steadily, after all, she is a mutated fire attribute physique.

When a laugh spread throughout the whirlpool, the people were still wrapped in several fiery red mist and carried to the stone bridge.

After passing the two tests, everyone has an understanding, that is, as long as someone meets the requirements, the test will end, according to these two tests, it is obvious that Ye Yifei is in the best condition, which makes everyone both envious and extreme, especially Liu Ruyan, who began to be angry in her beautiful eyes.

Although Ye Yifei took the lead, everyone still did not hesitate to start meditation and recovery, if they knew that a peerless spiritual weapon was involved, it would not be like this, it would definitely be a desperate understanding.

Ye Yifei suddenly had a feeling in his heart, that is, in the whirlpool due west, it must be a test of the golden qi.

"It's no wonder that the Heavenly Ladder Mountain was going to make me feel the golden fire qi at the beginning, and it was waiting for me here, but what will be the fourth vortex test?" Wan Er smiled, and began to recover himself.

Half an hour later, everyone stepped into the whirlpool due west again, but this time there was one less.

Liu Ruyan only recovered for a moment, and then stepped into the western whirlpool alone, not waiting for everyone at all.

"What a strong lady." Ye Yifei smiled slightly and didn't interfere with her, and let her move freely.

When everyone was once again brought to the bottom of the whirlpool due west, a cloud of golden mist slammed into everyone.

"That's really the case, haha......" I saw that in Ye Yifei's sea of knowledge, a huge golden dragon appeared.

The tall body of thousands of meters, as if cast in iron and copper, is extremely majestic, and the thick limbs stand there strongly, covered with golden spikes, extremely sharp, especially the thick sharp horn on the top of the head, which is completely contracted to a point at the tip, extremely sharp, so that people can see the strength of the sharp horn at a glance.

The whole body is covered with diamond-shaped scales, and the scales are also carved with dense veins, which are completely different from the veins of the two giant dragons, and are still exactly the same as the veins at the bottom of the whirlpool.

The golden eyes stared at Ye Yifei, who was also golden, but the golden dragon was golden, but Ye Yifei's gold was a transcendent gold, and his temperament was completely different.

Without waiting for Ye Yifei to observe more, the golden dragon directly buried his hair and launched a fierce attack.

With a bang, the sharp horns pierced directly into Ye Yifei's left chest, leaking out from his back, making him transparent.

"Hey, it hurts!" The powerful sharp corners give people the illusion of being punctured all over their bodies, as if their bodies are like paper paste, and they can't resist the other party's edge at all.

The hellish ordeal began again, but with the experience of the last two times, he was once again immersed in the comprehension of the golden qi.
