After dissecting the corpse of the fire beast, Lin Luo soon discovered something unusual.

In addition to the esophagus and trachea, there is also an elongated organ that closely resembles the trachea.

The elongated organ stretches downwards and eventually connects to a sac-like visceral organ located within the ribcage.

"Poof!"

Lin Luo picked up a branch next to him and gently pressed the sac-like internal organs.

Suddenly, some yellowish unknown liquid came out of the throat of the connected fire beast.

Looking at the unknown liquid that came out, Lin Luo's brows furrowed.

Because, at the moment when the liquid came out, Lin Luo also clearly smelled a disgusting and unpleasant smell.

"Be careful, if the water comes near the fire, it will burn all at once. ”

Seeing Lin Luo's movements, Ao reminded aside.

"And so it was. ”

Hearing Ao's words, Lin Luo's face suddenly showed such an expression.

Then, he immediately turned his head to Ao and asked, "Ao, do you know what this water is?"

For this pale yellow unknown liquid, although Lin Luo knew in his heart that it would definitely not be simple water, but the primitive people of this world called most of the liquid water, so Lin Luo didn't bother to correct it.

"I don't know. ”

Hearing Lin Luo's inquiry, Ao shook his head lightly and said, "I only know that when the water is close to the fire, it will burn all at once, and it can make the fire burn quickly and vigorously when the fire is just started."

However, the water cannot be stored for a long time, and if it is too long, it will all disappear. ”

Is it still volatile?

Hearing this, Lin Luo looked down at the liquids and secretly thought in his heart.

Flammable and volatile!

Such characteristics made Lin Luo think of the extremely common gasoline at once.

However, it is clear that these flammable liquids are not gasoline and smell very different from gasoline.

But Lin Luo can be sure that this is definitely similar to a fuel like gasoline.

After confirming the approximate composition of the unknown liquid, Lin Luo also basically figured out the secret that the fire beast was able to spray flames.

Obviously, the fire beast was not the demonic beast that Lin Luo had imagined before.

Because, after the dissection of the corpse of the fire beast, Lin Luo has been able to explain with science why the fire beast can spit flames.

Just as some poisonous snakes can shoot venom out of their hollow teeth, fire beasts spit out flames on the same principle.

First of all, when the fire beast spits out flames, it will first hit the flint in its mouth to produce sparks.

Then, the sac-like organ resembles a poison sac is squeezed hard to spew out the flammable liquid inside.

In this way, when the flammable liquid that is spit out encounters the sparks generated by the impact of the flint, it will instantly burn into a scorching flame.

In fact, this whole process is more similar to the fire-breathing vaudeville performance.

"It's really the size of the world, and there are no surprises!"

After figuring out the secret of the fire beast's spitting flames, Lin Luo couldn't help but sigh in surprise.

Such a wonderful animal, if it were to be on Earth, it would definitely cause a big sensation.

Thinking about this with a surprised face, when Lin Luo raised his head, he found that Ao had already turned around and walked into the cave to check on his Peng Bird War Pet.

And Lin Luo didn't get up, after finding a piece of animal skin to cover his mouth and nose, he continued to cut the sac-like organ with a dagger.

As the organ was cut, the pale yellow liquid inside instantly overflowed, making the unpleasant smell around it even stronger.

Lin Luo clenched his mouth and nose, and kept turning the sac-like organs to examine them, trying to figure out how the liquid in the fire beast's body, which could be used as fuel, was produced.

However, in the end, nothing was found, and no reason was studied for half a day.

Therefore, in the end, I had no choice but to give up.

After that, Lin Luo squatted down next to the other fire beast and dug out the two flints in the mouth of the fire beast in the same way.

And after digging out all the flints, Lin Luo also cut off a small piece of fire beast meat and put it in his mouth to taste it.

"Phew!"

However, as soon as he put the fire beast meat in his mouth and chewed it twice, Lin Luo immediately spit it out.

As Ao said, the meat of the fire beast is really very unpalatable, and the taste is sour and astringent, which is really difficult to swallow.

However, after this tasting, Lin Luo also guessed in his heart that the reason why the fire beast meat was so unpalatable must be related to the unknown liquid that could be used as fuel.

At the same time, its meat is also very likely to contain some toxins, after all, all liquid fuels on the earth are poisonous.

It's just that it may be because of the small amount of toxins, and the resistance of totem warriors to poison is many times stronger than that of ordinary people.

Therefore, most people like Ao will think that the flesh of the fire beast is just difficult to swallow.

In this way, after studying the fire beast inside and out, Lin Luo got up and stood up.

"Huh?"

However, just as he was holding a piece of animal skin and was about to wipe the blood-stained bronze spear, he let out a soft sigh as if he had found something.

......

Following

After resting in the cave for another night, Lin Luo woke up the next morning to find that Ao's Peng Bird War Pet had changed its appearance.

At this moment, after being treated by the spiritual liquid, the Peng Bird War Pet had completely lost the original charred feathers on its body, and replaced it with a new black and brown plump wings.

"Lin Luo, my training mission this time has been completed and I am going to return to the tribe, let's have a chance to meet again in the future!"

Ao walked out of the cave with his Peng Bird War Pet and said goodbye to Lin Luo.

"Okay, I'll see you later!"

Hearing this, Lin Luo also waved goodbye to Ao.

"Wow!"

After a brief goodbye, with a sharp crow, the Peng Bird War Pet flapped its huge wings and flew into the sky.

Under Lin Luo's upward gaze, the flying figure of Peng Bird quickly disappeared into the sky.

"Zixiao, let's go too!"

After bidding farewell to Ao, Lin Luo also turned over and rode onto Zixiao's back, and said to Zixiao in a loud voice.

"Roar!"

Hearing this, Zixiao let out a low roar, and quickly carried Lin Luo into the dense forest.

......

"Poof!"

Soon, about half an hour later, Zixiao stopped, and Lin Luo also turned over and got off Zixiao's back.

And at this moment, the place where Lin Luo was the edge of the Nan Forest that he had just come to yesterday.

Looking at the Nan Forest not far away, Lin Luo gathered his totem power and observed it carefully, and found that the surroundings were quite quiet, and there was no trace of the fire beast.

"Zixiao, you wait here. ”

After observing, Lin Luo turned his head and said to Zixiao beside him.

"Roar!"

Hearing this, Zixiao immediately roared and crawled into the bushes to hide his body.

And after Lin Luo finished instructing Zixiao, he quietly walked towards Nan Shulin.

However, as soon as he approached a nan tree at the very edge of the woods, Lin Luo immediately stopped.

Because, when he came to the Nan Forest again today, the main purpose was not for the fire beasts, but for the Nan trees in front of him.
