At the foot of Chishan Mountain, flames were everywhere, and even the soil was ignited, like a sea of ​​flames.

Five flame demons, comparable to mountains, appeared. Their wings spread out and covered the sky, and the sky suddenly became dark, like the end of the world before the collapse of the world.

Li Yu stood in the air, his clothes fluttered, and his face was calm.

He took out the Shenxiao Umbrella, looked at Zhu Lan next to him, and sent a message: "I'm three and you two, are there any problems?"

"Can you?" Zhu Lan frowned slightly and said worriedly.

"You should be very clear about my strength." Li Yu smiled softly and replied.

"Okay! I'll deal with two over there."

Zhu Lan stretched her eyebrows and smiled on her face.

After the transmission of the voice, she suddenly rushed to the two fire demons on the left, and her body quickly grew larger in the air, more than half larger than the size of the opposite side.

Zhu Lan spit out the Vermilion Bird Li Fire from his mouth, and the red flames increased the surrounding temperature again as soon as they appeared.

The mountains turned into magma, the ground melted into hollows, the grass and trees turned into flying ashes, and even the air was ignited, and the sky and the ground were covered with flames.

The surging red flames rushed towards the two flame demons, and the fire shone, burning everything!

Trepidation!

The two fire demons made a sharp and sharp roar, and one of them flamed the four wings, causing a violent storm, blowing over the stone mountain, crushing the giant wood, and blowing away the red fire in the sky.

The other two fire demons spit out black fire on one of them and black smoke on the other. The thick smoke rolls out to block the spiritual consciousness. Under the smoke, the black fire collided with the red fire and entangled it.

"snort!"

Zhu Lan let out a cold shout, and the Vermilion Bird Li Fire rose from his body, and dived towards the two flame demons.

The latter was not willing to be outdone and whistled and took the initiative to meet him.

The two sides broke out in the air, and the two flames of red and black and red were clearly separated. Among them, three huge black shadows kept colliding, making loud noises!

"It's my turn!"

After Zhu Lan took action, Li Yu held the Shenxiao Umbrella in his hand, and countless purple sky divine thunders suddenly appeared and hit the remaining three-headed fire demons.

The latter used black and red flames to turn into a sea of ​​fire and collided with thunder in the air.

Boom boom!

A huge explosion sounded in the air, and the power generated during this period even trembled in the solid space, dense cracks appeared, and then healed quickly.

"Some strength!"

When Li Yu saw the opponent blocking his attack, his face was calm, and the Divine Sky Umbrella rays in his hand, more Purple Sky Divine Thunder appeared, densely filled the entire space, and rushed down again.

In an instant, the purple thunder was like an ocean rushing towards the bottom, the space was shaking, the wind and clouds changed, the wind was wailing, and the earth was trembling!

The three-headed fire demon sensed unprecedented fear and fought desperately. The black and red flames soared into the sky. The terrifying heat wave melted gold and iron. The ground was scorched by high temperature and turned into glass-like mirrors, and then quickly melted into fiery red magma.

The Black and Red Fire Sea and the Zixiao Thunder Sea collided in the air. The former was broken by thunder without any accident and disintegrated on the spot.

The three-headed mountain-sized fire demon was submerged by the sea of ​​thunder, and the black and red flames were beaten into Mars and dissipated.

The thunder sea lasted for more than ten minutes and finally subsided.

Li Yu's spiritual consciousness expanded and looked downward. There was no trace of the Flame Demon.

The radius of hundreds of miles turned into magma, and then solidified, the ground turned black, exuding a strong smell of sulfur.

"What's this?"

Suddenly, Li Yu found three shining crystals from the solidified magma below.

He reached out and sucked three crystals into his hands.

Each crystal is larger than a fist, and is bright red and transparent, and is shining with a strange red light in the sun.

Li Yu could feel a pure fire-attribute energy when he held it in his hand.

"This is the fire crystal transformed by the Fire Demon after his death. It is also a strange thing and is of some help in practicing the magical powers of fire."

At this time, Zhu Lan also ended the battle and turned into a human form to come to Li Yu.

She saw the crystal in the other person's hand and explained with a smile.

"Does every fire demon have this kind of fire crystal after death?"

Li Yu put away the fire crystal and asked curiously.

"It's not necessarily, but generally speaking, the higher the cultivation level, the easier it is to be born." Zhu Lan shook her head and said.

"Does there be any fire demons we killed before?"

Li Yu nodded slightly, and then suddenly remembered something.

"Not noticed." Zhu Lan shook her head and added: "There are many such fire spiritual creatures in the secret realm."

Is this a rich woman?

Li Yu shook his head slightly in his heart and threw away his distracting thoughts.

He raised his eyes to Chishan ahead and asked Zhu Lan: "How are you? Do you need a rest?"

"No, it's just two fire demons, it's very easy."

Zhu Lan responded with a confident smile.

"Well, then let's go up the mountain."

Li Yu noticed that the other party's breath was normal and he didn't say anything.

The two set off again and flew towards the mountain.

But after flying for only about 3,000 meters, the two of them realized that the pressure was extremely heavy and they could only lower the height.

When they reached seven thousand meters, they felt as if they were carrying a mountain on their bodies.

After 10,000 meters, Li Yu and Zhu Lan had to stop flying and walk up the mountain.

After 15,000 meters, both of them were already sweating, as if they were carrying an ancient sacred mountain on their bodies. They had to use all their strength every time they raised their feet.

"How high is this mountain? I feel like I can't hold on!"

Zhu Lan sat on a rock, with several strands of fiery red hair wet with sweat and stuck to her forehead.

Her eyes looked toward the top of the mountain, and there were only red clouds and mists in her eyes.

The mountain was filled with pressure, and even the spiritual consciousness was suppressed.

Zhu Lan couldn't see through the clouds and mist, so naturally she didn't know how far she was from the top of the mountain.

Li Yu stood not far ahead. Although he was sweating, his situation was still better than Zhu Lan.

Although he is a human race, he is in martial arts and practices top skills like the "Emperor Sutra", and his physical body is not weaker than that of the demon race.

"The pressure on this mountain should be left by Senior Chi Yan Bird, and the purpose may be to intimidate the creatures in the secret realm and select suitable inheritors."

His blood and energy flowed, evaporating sweat on his body, looking at the other party and said, "If you want to get inheritance, you must persist no matter what."

"Although that's the case, you don't have to be so true!"

Zhu Lan smiled helplessly, got up from the rock and continued walking forward.

She quickly caught up with Li Yu and surpassed the other party. After walking for a while, she turned around and saw that the latter was still stuck in place.

"Why don't you leave?"

Li Yu moved his muscles and shook his head and said, "It's you who want to inherit it. Why should I follow you up? Why would I go around the mountain and maybe I can find some treasures."

What you said makes sense, but I didn't know how to refute it for a while.

"Just think it through."

Zhu Lan was stunned and said inexplicably: "Then I will continue to go up the mountain and meet at the foot of the mountain."

"good!"

Li Yu agreed and smiled at the other party, "Come on!"

Zhu Lan blinked her eyes and smiled, "Well, I will."

After she finished speaking, she took a deep breath, turned around neatly, and walked towards the mountain with firm steps.

"Why are there only one going up the mountain?"

Above the top of Chishan Mountain, in front of a hall, a man wearing red armor stood.

He was burly and sharply looked at the mountainside, bringing Zhu Lan and Li Yu all the way.

He was observing in secret since the two appeared at the foot of the mountain.

He also saw the performance of the two people behind him seriously and nodded in his heart.

But now one of them suddenly stopped moving, which aroused his curiosity and doubt.

All living beings who can come to this secret realm should have been informed by their master.

He didn't expect that someone would be unmoved by the inherited treasures of the demon immortals.

"Go down and take a look."

The man with red armor thought for a moment, looked at Zhu Lan who continued to climb the mountain, and his figure flashed and disappeared from the spot.

After Li Yu parted with Zhu Lan, he opened his eyes and used the qi-looking technique to wander around the mountains.

But in a short while, he found many good spiritual objects.

"It should be said that it is worthy of being a mountain that carries the inheritance of demons and immortals. There are really many medium-grade fire spiritual creatures!"

Li Yu took down a sixth-grade fire peach spirit root, and his face showed a happy smile like an old farmer who harvested wheat.

When he was about to go to the next place, a figure suddenly appeared on a flat ground in front of him.

The visitor was covered in red armor, exuding an abyss like an abyss, which made Li Yu's expression suddenly become vigilant.
