My power increases a little bit every second, and I become the most powerful demon

Lin Qingyun was the first to enter the cave. As soon as he entered, he felt a wave of heat coming towards him.

The temperature inside was extremely high, reaching a level that made him feel uncomfortable.

In addition, the spiritual energy inside was also extremely rich, and this spiritual energy also contained scorching heat.

This is why the waterfall outside is hot.

"Huh~"

"Wow, it's so hot..."

Lin Yuexi then came in, and she was also shocked by the temperature in the cave.

However, she has the power of fire in her body, and has a certain resistance to such a temperature.

"The spiritual energy is so rich, there must be good treasures in it!!" Lin Yuexi looked inside expectantly.

Lin Qingyun said to Lin Yuexi: "Go in first, you follow behind."

"Hmph! What are you trying to be cool about~" Lin Yuexi snorted lightly, but still stood behind Lin Qingyun silently.

Lin Qingyun was surrounded by electric light, ready to deal with any possible danger. He walked slowly into the cave.

The cave was more than 10 meters wide, quite spacious, and it was pitch black inside. Lin Qingyun wanted to use his green soul eyes to explore inside, but he only saw a red.

Those were all the spiritual energy filling the cave. It seemed that this skill still had some drawbacks.

As they gradually went deeper, the temperature around them became higher and higher.

"Huh?!"

"This is..."

"Fire Cloud Ganoderma!"

At this time, Lin Qingyun noticed that there were several red Ganoderma lucidum growing on the stone wall of the cave. There were cloud-like patterns on the crown of the Ganoderma lucidum. These characteristics were the Fire Cloud Ganoderma lucidum that Lin Yuexi needed.

Hearing this, Lin Yuexi hurried over to take a look, and her eyes suddenly lit up.

"Really!"

"We are so lucky~"

"It looks good, but the size is not long, but it is enough."

"Maybe it is because of the rich fire spirit here that they can grow so well!!"

Lin Yuexi was very happy. She didn't expect to find a medicinal material so quickly.

This made her more curious about the things inside.

She hurried over, took down the Fire Cloud Ganoderma on the stone wall, and put it in her own bag.

"Keep going!"

"I seem to see something vaguely."

Lin Qingyun said softly.

After walking for about two minutes, they did not encounter any danger. As they went deeper, the cave gradually became wider.

During this period, they successively found several kinds of fire-attributed materials and treasures, all of which were beautifully collected by Lin Yuexi in her bag.

These are all high-level materials with fire attributes, which are of great help to her.

In addition, they also found some feathers on the ground, and... the body of a demon beast.

The body of this demon beast had become shriveled and withered due to the high temperature. It had a pair of wings over five meters wide, and was covered with a layer of red feathers all over its body.

"What kind of demon beast is this?!"

Lin Qingyun carefully examined the body.

"It seems to be the body of a fire-feathered bird, and these feathers were also left by it."

"This kind of demon beast is not rare, and its bloodline is also at the ordinary level, the highest is only the fifth level..."

"Looking at the size of this corpse, this bird should have been the fifth level when it was alive."

Lin Yuexi is experienced and came to a conclusion after observing it.

"Fire-feathered bird..."

"Since it is dead, what is releasing high temperature?!"

Lin Qingyun was a little confused.

"I'm not sure, I have to go in to find out."

"This fire-feathered bird should have died of serious injuries. One of its claws is missing, and the bones in its abdomen have been broken." Lin Yuexi shook her head.

It seems that I can only go to find the truth myself.

Suddenly, a strong heat wave was released from deep inside the cave. Lin Qingyun's breath was choked, and he felt that all the hair on his body was about to be burned.

He quickly released the Thunder Tiger Armor to cover himself, and looked at Lin Yuexi behind him.

"Are you okay~"

"No... I'm fine..."

Lin Yuexi's face looked a little ugly, but she could still bear it.

"I knew I would bring Ningshuang with me, so I could resist some of the heat."

The heat wave gradually dissipated, and Lin Qingyun took this opportunity to rush to the source of the heat wave.

After running for about dozens of meters, Lin Qingyun came to the end of the cave and finally found the source of the scorching temperature.

That... turned out to be an egg! !

Lin Qingyun stretched out his tiger claws and rubbed his eyes, a little unbelievable.

At the end of the cave, there was a huge bird's nest on the ground, and at this moment, the bird's nest was burning fiercely due to the high temperature.

In the middle of the burning bird's nest, there was a bird's egg that was about the size of his palm.

The bird's egg emitted a faint flame, and on the surface of the eggshell, a substance like magma was constantly flowing.

"What kind of egg is this!!"

"Why is there a faint pressure..."

Lin Qingyun was a little surprised that such a high temperature and rich spiritual energy was released from this egg.

Could this egg be hatched by the fire-feathered bird? !

Can such an ordinary monster have this? !

[Fire-feathered bird egg (mutation): It contains an unknown monster species, and it seems that the cub inside is about to hatch~]

It turned out that a mutation had occurred.

At this time, Lin Yuexi also followed in, and she saw the bird's egg at a glance.

"This bird's egg has actually mutated!"

"Should I say it, our luck is pretty good~"

Lin Yuexi looked at the egg up and down with interest.

"Can you identify the species of the monster cub inside?" Lin Qingyun asked casually.

Lin Yuexi shook her head and said: "The mutated monster egg can only be identified after it breaks out of its shell."

"Mutated monster eggs are extremely rare and highly uncertain. Some of the mutated monster eggs hatched from cubs with congenital defects and died young after only a few hours. "

"But there are also rare cases where mutant monsters with epic or even legendary bloodline will be hatched."

"That kind of monster is basically rare. If it grows up smoothly, it is guaranteed to be a strong monster at the level of a monster."

Lin Yuexi looked at the monster egg with burning eyes.

"Looking at this posture, the mutant cub inside is definitely not simple!"

"If we can hatch a legendary bloodline, then we can do it~~"

Although Lin Yuexi had seen a lot in her previous life, she had never seen a mutant monster.

Now I can actually meet one here, which is really magical.

She had been silently planning in her heart to subdue this mutant cub and become an aid to her revenge~~

What Lin Qingyun is thinking now is, if he swallows this egg directly, will his bloodline evolve again~~

Also at this time, the mutant monster egg... changed...
