Dragons' breath is a physiological act, but in essence it is an innate magical ability, and there is something in their physiological structure called "basal blood vessels", which is an organ unique to dragons, it is an extremely complex blood vessel, it looks like something like a rubber water pipe, it has a muscular outer layer that can pump blood like a heart.

This outer layer allows the basal vessels to rapidly contract and dilate from one end to the other, pushing blood flow to the upper stomach.

That's where the dragon's spitting weapons come from.

Dragons rely on their hearts to generate blood flow that gives them spitting weapons and other abilities, while basal blood vessels are responsible for channeling energy-rich blood from the heart into the upper stomach of their muscular stomachs.

So, the "spitting weapon" that humans take for granted is actually a misnomer, because the fire, poison, acid, or other substances are delivered from the upper stomach, not from the lungs.

More precisely, the flow of energy is vomiting rather than exhaling.

Caesar had the same physiology as other black dragons, but unfortunately, his heart could not produce elemental magic like a true dragon, so that breath was impossible for him.

Therefore, the dragon's breath, which looks majestic, has become a piece of Caesar's heart.

But this time the slumber changed his physiology, and in Caesar's body, new organs were generated, and in the upper layer of his throat, three sac-like organs appeared that could secrete special fluids, each of which had a tube connected to the valve and the organ, and the three catheters finally converged into one, and the exit was roughly located in the roof of his mouth.

The accompanying musculature allowed Caesar to control the nascent organ with ease—and it was only a matter of squirting fluid out of the cavity, and for some protective measure, he was unable to draw air into the cavity anyway.

"Hmm, strange feeling."

Caesar woke up and felt the difference in his body, and couldn't help but scratch his throat, his throat itched, as if something was stuck there.

When he opened his mouth, the itching sensation intensified, and Caesar clearly felt three "switches" in his throat that could be controlled by himself, and his body was about to move.

Caesar controlled the musculature in his body and decided to try the effect of the implanted spitting weapon, and when he opened the valve in the first sac cavity and contracted the muscles, a stream of viscous fluid immediately gushed out of the throat cavity along the catheter.

The next moment, the black dragon erupted in flames.

The blazing flames flickered, and when Caesar reacted, he immediately closed the valve.

This black dragon, which has a body length of seven meters, covers its mouth, hunches its waist, and turns its head like a thief to look around, if others know that the black dragon can spew flames, I am afraid that they will be immediately shocked, and once the news spreads, he will immediately attract onlookers.

Fortunately, bound by the oath of God, the orcs were not afraid that Caesar would not fulfill their promise, and after leaving the specific location of the clan, they hurried back to the tribe without stopping, and the two young dragons had long since left, and now they did not know where they were—the area was now empty.

"How can I breathe flames, it's not scientific."

Caesar muttered twice and decided to try again, this time staring at the tip of his kiss, remaining focused, his nerves sharpened to make out the fleeting images:

When he opened his mouth, a viscous liquid erupted from his mouth, a liquid of unknown substance, which immediately burned when it met the air, forming a high-temperature flame.

To outsiders, it's like this black dragon breathing fire.

Caesar burned a small bush to ashes, and he tried, under the control of the musculature, that he could control the amount and form of the liquid sprayed at will; That is, he can spew a stream of flames, fireballs, fan flames, and so on.

"Uh......"

Two minutes later, looking at the raging fire in front of him, Caesar burped, the muscles of the sac cavity twitched a few times, and no fresh liquid gushed out.

In other words, the amount of flammable liquid in the capsule cavity can sustain him for two minutes to continuously spew flames, and the combustion efficiency of this unknown liquid is very high, and it is quite viscous, and some droplets will contaminate the surface of the target for continuous combustion.

Don't look at the two minutes is very little, but how can a dragon breathe continuously in battle, and Caesar is quite satisfied that it can last for such a long time.

And don't forget that there's more to his newly formed organ than this one.

He rested for a while, waited until the musculature that matched the sac cavity was no longer sore, opened his mouth, and turned on the second valve switch.

This time, Caesar clearly felt the coldness in his throat, and the alternating feeling of hot and cold made him sneeze, and a puff of white gas was sprayed out.

The white gas dissipated surprisingly quickly, and when Caesar didn't know why, he found that the scorched tree that was still burning in front of him was instantly frozen and turned into a beautiful work of art.

Caesar immediately took a few steps closer, tentatively holding the frozen coke with his claws, the temperature of the things in his hands was so low that Caesar felt a slight pain in his right paw, and he gently pinched it, and the coke turned into countless ice slags in the click.

"Awesome."

He couldn't help but sigh in admiration, such a temperature and freezing speed were stronger than any kind of cryonics on the earth he knew, and the form of expression was comparable to the unpredictable freezing magic.

"How do you feel familiar......

He stared at the shards of ice ballast all over the ground, and he couldn't help but think of a huge black dragon facing a group of human adventurers, yelling "absolutely cryogas" and then puffing and puffing in his head......

Stop!

Caesar shook his head vigorously, a little embarrassed, God knows where the name of this shameful move full of middle two breath came from.

The liquid in the third pouch didn't surprise Caesar so much, but it did give him a spitting weapon that could be exposed to the outside world, and it was acid that quickly corroded the objects it touched.

Caesar had seen Garon and Blackxia's strong acid breath, so he couldn't help but make a simple comparison, his acid seemed to be a little inferior to the young dragons in terms of strength, but it also had an advantage in comparison, that is, the amount was full, at least the young black dragon could not continue to spit strong acid for two minutes in a row - that would vomit their stomach juice.

After getting acquainted with the spitting weapon, Caesar was excited for a moment, but then realized the potential danger.

He is a cautious man (dragon), and although he does not know the mechanism on which the newly formed organs are capable of generating and storing these extremely dangerous fluids, he knows that the other organs of his body have not changed.

Therefore, once this critical organ is injured and damaged, the fluid is likely to leak into the body and flow backwards, in which case, there is a high probability that it will directly cause his death.

Caesar touched his neck, but fortunately, the new organ grew in the upper layer of the throat, in the neck covered by the chin, which was already within the scope of his key protection, and if he did not deliberately raise his head, it would be difficult to hurt this position in ordinary combat.

"But it would be safer to have a big iron chin." Caesar thought as he touched the edge of his kiss.
