"Die, boy!"

The other party grinned, smiled gloomily, and without waiting for Li Mu to react, he had already rushed in the direction where Li Mu was.

At the same time, his hands were constantly changing with various seals, but the blue-gray hollow was getting bigger and bigger, and even had already undergone substantial changes, wrapped in an incomparable ferocity, and it was only in an instant that it had appeared in front of Li Mu.

Boom!

Li Mu didn't dare to confront it, knowing that if he touched the hollow, the person would be instantly sucked into the hollow, so he could only raise the knife and smash it on the arm of the 'Luo Zhengfan'.

Then there was a deafening explosion that could be exploded, and countless small cracks appeared on the walls of the entire room because of the continuous fight between the two, and in just a few minutes, the room gave people a crumbling feeling, afraid that if the two continued to fight like this, the whole room would collapse.

Bang Bang Bang!

The sound of metal handover continued to sound, and the energy and speed of the 'Luo Zhengfan' became more and more ruthless, and became more and more ferocious, Li Mu was suddenly a little unable to parry, and his body kept retreating.

And every time he took a step back, he stepped on the ground under his feet, and he stepped back more than a dozen steps one after another, and the person had already retreated to the door of the room, and there was no way to retreat.

"Hehe, I see how you escape this time, since you have entered my big array, you will obediently be my feed, too tough, I'm afraid there is no good fruit for you to eat, and the two of them are desperate to protect you, you should be the most important of the three, since it is so important, I should think about how to deal with you!"

'Luo Zhengfan' looked at Li Mu, who was already leaning against the door panel, with a gloomy face, and laughed softly.

"Silver Mirror, I need your help!"

Li Mu's eyes moved slightly, and he spoke to the silver mirror in his thoughts.

"This person is too strong, even if you and I join forces, we may not be able to beat him!"

After a long time, the silver mirror opened his mouth quietly.

"If you can't win a fight, you should always give it a try!"

After a while, Li Mu's body trembled slightly, and after a slight silence, the momentum of the whole person suddenly rose.

"You.... You're hiding your strength?"

Seeing this, the other party couldn't help but take half a step back, and looked at Li Mu, whose energy was constantly rising, with a vigilant expression.

"yes, wouldn't it be better to surprise you?"

Li Mu tried his best to suppress the feeling of swelling pain in his meridians brought by the powerful energy, and shouted in a low voice with a mouthful of silver teeth.

Call!

The voice fell,

A black flame nearly half a meter high suddenly erupted from Li Mu's body, and then completely enveloped Li Mu.

The black flame was colorless and tasteless, and it had no temperature, but even so, under Li Mu's feet, countless cracks had already appeared because of the burning of this flame, and the door panel behind him was almost instantly swallowed by the flame and disappeared into nothingness.

Looking at everything that happened to Li Mu, a touch of shock flashed in the other party's heart, who is this kid sacred?

Not only can he hide his strength, but he also hides such a strange flame in his body, if he is not mistaken, the appearance of this flame should be almost the same as that on the hilt of the knife just now.

It's just a trace of fire that has already distracted me to remove it, and if this churning flame is stained with half a point, what should it be?

"No matter what, you won't be able to run today!"

For some reason, a touch of anger suddenly rose in Luo Zhengfan's heart, so he gritted his teeth at Li Mu and shouted.

Boom!

Before his words fell, Li Mu had already turned into a shadow and came to him in an instant.

The distance between the two was already extremely close, and Li Mu's speed had increased exponentially, coupled with the black fire on the surface of his body, 'Luo Zhengfan' almost didn't think about it, and instantly exploded backwards.

Retreating to the point where there was no way to retreat, 'Luo Zhengfan' had to raise his fists and smash angrily at Li Mu's body.

Unexpectedly, Li Mu didn't want to fight with him at this time, but in an instant, he had already dodged the attack of 'Luo Zhengfan', his footsteps moved slightly, and he appeared on the other party's back in an instant.

Boom!

Li Mu clenched his fists, and a pitch-black energy kept burning, smashing out vigorously at 'Luo Zhengfan's back. At the same time, there was a slight sonic boom in the air.

A low impact sound suddenly sounded, and Li Mu's fist had already slammed into the opponent's back.

The floor under the feet of the two could no longer withstand Li Mu's full blow, and it shattered, and the two of them suddenly fell from the second floor to the first floor.

"Think it's okay to hit me?"

On the way down the two, not only did the other party not show any signs of injury, but smiled suspiciously, and then raised his left leg and kicked at Li Mu.

When falling, the body couldn't grasp the balance at all, and in the face of the flying kick, Li Mu's body kept writhing like a loach, narrowly avoiding the blow of 'Luo Zhengfan'.

It's just that in the blink of an eye, the two intersected for a few more rounds, but the other party was a little afraid of the black flames on Li Mu's body, and he didn't dare to fight with him, and he was much worse in attack.

Call!

Li Mu saw this opportunity, and with every move, a trace of black flames rushed to the other party's body, and then disappeared on the surface of the body.

"What kind of fire are you, what kind of fire are you?"

A flash of surprise and even a hint of fear flashed across the other party's face, because he found that those tiny flames not only rushed out of the entire meridians, but even a section of the meridians had been completely burned, and the flames burning in his body, he found that he was powerless to clear them out at all.

"The fire that kills you!"

Li Mu let out a low snort.

Then the flames on his body suddenly retracted, and when he reappeared, he had already turned into a black long dragon and swooped down towards 'Luo Zhengfan'.

Oh!

A dragon roar that resounded through the heavens and the earth suddenly sounded, and the other party's figure was instantly enveloped.

Yes!!

Then, within the black dragon, a roar suddenly erupted.

Li Mu's eyes narrowed slightly, but he found that the other party's figure was gradually getting bigger, taller, and even stronger.

In the blink of an eye, it has become a giant of about two meters, but it has not stopped because of this, but continues to grow high...

"Die!"

The little giant roared angrily, raised his foot and stepped on Li Mu.

Boom!

A big foot about a meter long hit the ground with a bang, and several cracks opened in the ground.

Then the whole room trembled again, and it looked like it was about to collapse....
