These black trees attacked again, like countless black dragons rising into the sky, aiming directly at Liu Fei.

"Boom!" The roar of the flames exploded across all directions, and the bright flames even illuminated half of the sky.

All those black threads were blown away, and while they were slowly floating in the air, they were all burned to ashes by the flames.

Liu Fei frowned, tapped his toes in the air, and retreated suddenly.

But those black trees seemed not to give up, and continued to surge forward with swaying lines like pushing hands.

Liu Fei held the sword in one hand, and his speed was extremely fast. The sword shadows were thick in the air, and he retreated while crushing these attacks.

About a thousand meters away, these black lines paused for a moment, and then they all slowly retreated.

Liu Fei fell to the ground and looked up at the Black Cloud Mountain. His face was still a little confused, obviously he hadn't figured out a way to get through this level yet.

After shaking his eyes a few times, he waved his right hand and the cauldron floated in the air.

Put your fingers together in front of your nose: "Open!"

In an instant, several figures flew out of the cauldron and all fell to the ground.

"Liu Fei, are you okay?" Xuemei and Park Aifei hurried over, each grabbing an arm and looking up and down.

"I'm fine..." Liu Fei shook his head.

The nine people in Sima Bo glanced at each other, all gathered around Liu Fei, looked up and down carefully, and praised with a heartfelt smile: "Sir, you are really awesome!"

An Borou smiled sweetly, with a look of admiration and admiration: "Your Majesty really did not choose the wrong person. With your majesty, you will definitely succeed this time!"

Sima Bo also smiled and shook his head: "I'm really ashamed of myself. Thanks to my husband for saving me."

Liu Fei waved his hand: "No need to say this, we just have to help each other this time, otherwise we will definitely not be able to get through!"

Everyone nodded, with a bit of joy on their faces.

Xia Houliang covered his wound, hesitated for a moment, walked over and bowed deeply: "Thank you, sir, for saving my life."

"Xiahou Liang's death is hard to avenge!"

Liu Fei immediately took his hand: "It doesn't have to be like this."

Xia Houliang raised his head, his eyes full of respect. After all, he was already prepared to die here, and he never thought that he could survive.

Of course, the most unexpected thing for him was that Liu Fei would actually save him. He was like a soldier who thought he could be cannon fodder and was saved by a general. He felt so grateful that it was beyond words.

"Alas..." Gan Xingliang sighed and cupped his hands towards Liu Fei, "Sir, I have to apologize to you, because at first I thought of you as a cruel and ruthless person and thought that you would definitely look at us.

Die one by one."

"It's true that I judge a gentleman's heart with a villain's heart, and I feel ashamed and ashamed!"

Liu Fei smiled and shook his head slightly: "This is also our first run-in. If anything happens down the road, everyone must help each other."

"Yes!" Everyone nodded heavily, their eyes bright, looking at him with admiration.

Even Yuwen Xuerui, who has always been a bit cold, showed a bit of respect.

Liu Fei took a few steps towards Black Cloud Mountain, squinting his eyes and frowning: "Look, the trouble has not been eliminated yet."

Everyone walked up to him, lined up in a row, and looked forward. They saw black trees standing on Black Cloud Mountain again, like a monster covered with black stiff hair.

"This..." Sima Bo looked ugly, holding a folding fan in his right hand and constantly flapping his left hand.

"How could this happen?" Yuwen Xuerui's eyes widened, "Didn't we clear out all these things? How could it appear again?"

Everyone's eyes were focused on Liu Fei. After all, Liu Fei was the only one outside just now, and only he knew what happened.

Taking a deep breath, Liu Fei spoke slowly: "Those black gases shot out, and after being shot down, they took root on the ground and grew into these black trees."

"If we don't find a way to deal with the black energy, then these black woods will be endless, and we won't be able to kill them all with any tricks!"

Everyone took a deep breath and looked shocked.

"How can we fight like this?" Gan Xingliang scratched his head and gritted his teeth.

Several women also looked at each other, looking worried and helpless.

After all, so far, no one in the entire underworld knows where the roots of Black Cloud Mountain are...

Liu Fei thought for a while, then turned to look at Sima Bo and the other nine people: "I have a question for you: Is the origin paper of Heiyun Mountain related to the black bear spirit?"

Sima Bo was stunned for a moment, then nodded: "According to the information we have...that's it."

Liu Fei touched his chin: "Is there a possibility that the black energy comes from that black bear spirit? This guy is hiding under the Black Cloud Mountain."

"As long as his power is not extinguished, everything outside will never disappear."

"This..." Sima Bo lowered his head and pondered for a moment, then nodded slowly, "What Mr. said does make sense."

He raised his head suddenly, his eyes very firm: "No, that's how it should be!"

Liu Fei turned to look at the others: "What do you think? It doesn't matter whether it's right or wrong. As long as you have something, just say it and let's discuss it together."

Everyone looked at each other, then all shook their heads.

An Borou rubbed her hair: "I think what you said is the truth."

Several other people thought for a while, and then all nodded in agreement.

"Okay!" Liu Fei turned around and looked at Black Cloud Mountain, "Let's take this as a consideration for the time being. Whether it's a legend or a story in your underworld, is there any explanation on how to enter the underground of Black Cloud Mountain?"

"Hmm..." Sima Bo thought for a moment and looked helpless, "I've never heard of it."

After he finished speaking, he looked at the other eight people, who all shook their heads.

Everyone fell into silence for a while, each bowing his head and thinking.

The dark wind was blowing in waves, and several people stood here like sculptures, motionless, and the atmosphere became more solemn.

A full quarter of an hour passed like this. After Liu Fei carefully thought about the battle just now, a guess gradually formed in his mind.

He squinted his eyes, swayed left and right a few times, and gradually became brighter.

After looking at these people, he suddenly waved his right hand. After the fire flashed, the Fire Dragon Sword was already in his hand.

"Sir?" Everyone was confused.

Liu Fei looked at the Fire Dragon Sword: "When I fought with it just now, the Fire Dragon Sword could indeed restrain the black aura of death."

"Do you think we can try it with the Fire Dragon Sword?"

Sima Bo stepped forward and looked at the Fire Dragon Sword, his eyes lit up: "You want to use the pure Yang energy on the Fire Dragon Sword..."
