The Demon Flame Mountain, huge and boundless, is shrouded in a poisonous miasma, but it is difficult to hide its charm.

Now, those outlaws who are looking for treasures are dead and wounded, and those who dare to enter the Demon Flame Mountain at this time are basically the children of the great sects with profound backgrounds, such as Yan Falling City and his party.

Of course, in addition to the big sects, there are also those strong people who have sufficient confidence in their own strength, such as the mysterious bookstore owner and the old Taoist.

At this time, the two of them were like two bolts of lightning, constantly shuttling and colliding on the top of the Demon Flame Mountain, causing the mountain to crack and the wind to hunt.

Countless boulders were knocked down from the top of the mountain by them, frightening the disciples of the great sects to retreat one after another, lest they be hit.

"Niubi, you haven't worked in vain all these years, haha!" laughed the bookstore owner who was called an old immortal by the old Taoist priest.

Although he is thin and weak, his attack method is very rough, and there is the power of mountains and seas between his fists and feet, and every punch carries the sound of wind and thunder, which is extremely terrifying.

"Old immortal, your body is strong again, do you want to be sanctified in the flesh?"

The old Taoist priest looked serious, and the spiritual weapon in his hand was like a white dragon, agile and amazingly lethal, and a hundred-zhang boulder was swept away, and it immediately turned into powder.

"In the Yuanling Continent, except for Mu Qiankun and Jiang Taichu back then, whoever dares to speak of the holy word can take off a mortal word, and the old man will be satisfied!"

As he spoke, these two old guys who didn't know how many years had lived fought together again.

"Princess, it seems that the old guy has really been brought in, we have to act quickly!" said Old Wu Hu beside Yan Chengcheng.

"Well, I don't know where it is sacred, and it is so fierce to fight with the old ancestor!"

Yan Chengcheng's expression was solemn, but he was also full of doubts.

In addition to the Vermilion Bird Sect, several groups of people also appeared in several other directions of the Demon Flame Mountain, one of them wearing standard robes and robes, and the sleeves were embroidered with coiling dragons of different colors.

......

At the foot of the Demon Flame Mountain, Mu Qingtian's body was shrouded in purple light, and he walked into the area as black as ink, and every time he walked a section, he would sit down and take a look at it.

During his enlightenment, the Chaos Demon Tree would grow out of his body, constantly devouring the pure demonic energy around him, and strengthening his body.

Finally, Mu Qingtian came to the center of the dark area.

In front of him, a pitch-black and shiny lotus flower was suspended, and the space around the lotus flower was constantly distorting, as if it would collapse at any moment.

Mu Qingtian knew that this black lotus should be the legendary Burning Sky Demon Flame.

"Burning Sky Demon Flame, I know that you have followed a powerful master, but I will not be worse than any of your previous masters, if you are willing to follow me, I will take you to enjoy the infinite scenery of the heavens and all worlds in the future!"

When Mu Qingtian saw this strange black lotus, he was suddenly arrogant and moved.

If the big black dog was here, he would definitely be sarcastic for his nonsense and shamelessness, but at this moment, Mu Qingtian's face was full of seriousness and confidence.

Rumble!

I don't know if the Burning Sky Demon Flame was angry at Mu Qingtian's wild words, or if he agreed with his words, it suddenly exploded, turned into a black flame that could burn the heavens and the earth, and rushed towards him.

"It's a big game!"

Mu Qingtian was shocked, and immediately urged the Demon Tree to release endless purple qi to protect himself.

But the Burning Sky Demon Flame was so terrifying that it was able to burn through the energy shield built by the Demon Tree.

The Burning Sky Demon Flame's actions completely angered the Demon Tree, and it immediately rushed out of the endless roots, wrapping Mu Qingtian tightly.

Mu Qingtian sat on the ground, urging the Demon Tree to fight against the Burning Sky Demon Flame, and frantically operated Aoki's divine skills all day long, refining the power of the Demon Flame that invaded the Demon Tree.

Rumble!

Mu Qingtian's provocation made the Burning Sky Demon Flame even more angry, and it erupted into even more powerful flames, filling the entire underground world, and constantly spreading outward.

Seeing this situation, the Dark Demon Worm dared to stay for a long time, and immediately flew out wildly, but it happened to collide with the little little guy and the big black dog who came in the hole.

"It's over, Mu Hei didn't get out, but the two of us are going to get in!"

When the big black dog saw the dark demon worm, where did he dare to have the idea of rescuing Mu Qingtian, and immediately fled with Xiao Budian frantically.

However, no matter how fast they were, they couldn't be faster than the speed of the Burning Sky Flame.

Seeing that the big black dog and the little one were about to be overwhelmed by the black flames, the dark demon worm suddenly stretched out its tentacles, wrapped the two of them, and rushed out of the underground passage.

"Big man, why did you save us?"

Coming to the safe area, Xiao Budian couldn't help but ask.

"You're friends with that adult, and he'll blame me if he doesn't save you!" said the Dark Demon Worm Urn angrily.

"Hey, the adults you are talking about are our bosses, why?"

Xiao Budian is a little confused, isn't this big guy dragging the boss in?

How did it take only a month for the boss to become its adult.

"Your uncle, Mu Hei is a blessing in disguise, how did such a good thing not fall on the dog master!" said the big black dog unevenly.

"A person without a Demon Dao Origin on his body is close to the Burning Sky Demon Flame, and there is only one way to die!" the Dark Demon Worm glanced at the big black dog and said disdainfully.

"Damn, the dog was actually despised by a worm!"

The big black dog was very unhappy, but after feeling the breath of the dark demon worm, he immediately closed his mouth again.

And in a cave in the Demon Flame Mountain, the people of the Vermilion Bird Sect finally met the group of people wearing green dragon robes.

"Qinglong Sect, what do you intend to enter my Vermilion Bird Country so blatantly?"

Yan Chengcheng held a long sword and pointed at the people of the Blue Dragon Sect.

"Although the Demon Flame Mountain is in the territory of the Vermilion Bird Country, it is not your Vermilion Bird Sect's private property, besides, the treasures of the world, those who can get it, my Qinglong Sect does not steal or rob, and strives for it with strength, what's wrong?"

An old man came out of the ranks of the Blue Dragon Sect and looked at the people of the Vermilion Bird Sect coldly.

Due to the ambush of the Hell Killer, more than half of the manpower on the Vermilion Bird Sect's side had been lost, and with the aura of the old man of the Blue Dragon Sect being as vast as the abyss, they were no match at all.

While conflicts were frequenting in various parts of the Demon Flame Mountain, a strange and huge magic tree grew in the underground sea of fire.

This magic tree is like a black hole, constantly devouring the black flames around it.

As time passed, the magic tree grew larger and smaller, while the flames grew smaller and smaller.

At a certain moment, Mu Qingtian, who was sitting in the center of the magic tree, suddenly opened his eyes.

But the strange thing is that his eyes can't see the pupils, only a piece of black, like two black holes, deep and weird.

"Close!"

Mu Qingtian snorted lightly, and the huge demon tree immediately shrunk, returning to his dantian, and merging with the Chaos Demon Tree.

At this time, the Chaos Demon Tree was three feet high, and among the scattered leaves, there was an extra leaf as black as ink, which was in the shape of a flame, and a black lotus flower was suspended on it, which was very miraculous.

"I see!"

When Mu Qingtian saw such changes, his heart suddenly understood.

It turned out that every time he gained a new ability, the Chaos Demon Tree would materialize that ability on the leaves.

He learned alchemy, and a leaf in the shape of a Dan furnace appeared.

He learned the Tyrannosaurus marksmanship, and a spear-shaped leaf appeared.

Now that he had refined the Burning Sky Demon Flame, a flame-shaped leaf appeared in the Chaos Demon Tree to carry it.
