"Little bastard, you must die today!"

The Black Tiger Demon King roared hideously, and a pair of tiger claws, with terrifying tearing force, slapped down at Mu Yunfan.

"Dead?"

"Hmph, it is not known who killed the deer."

"But now, let's clean up this Black Tiger Demon King first."

Mu Yunfan snorted coldly, and as soon as his figure moved, he disappeared in place.

"Boom!"

And just after Mu Yunfan disappeared in place, the Black Tiger Demon King saw Mu Yunfan appear in front of him.

"Huh?"

"You're able to teleport?"

The Black Tiger Demon King was shocked.

But then, its eyes showed a rich and incomparable greed, his body trembled, and suddenly, a thick layer of black scale armor appeared on his body, and on top of these scale armor, a layer of dark light flashed.

"It's ......"

Mu Yunfan's eyes narrowed slightly, he stared at the scale armor on the Black Tiger Demon King, and immediately in his mind, a lot of information poured into his mind.

This Black Tiger Demon King is one of the top existences of the Black Tiger Clan, named 'Black Tiger Demon King', and has a strength comparable to the peak of the Spirit Fetal Realm.

This level of demon beast is definitely the overlord of the last party in the entire Northern Wilderness Demon Domain.

The toughness of the skin of this kind of demon beast can even be comparable to something like a golden stone, even if a strong person in the spirit fetus realm wants to break through their defenses, it will take a lot of effort and an extremely long time to succeed.

Therefore, once this Black Tiger Demon King is injured, his body is also extremely terrifying.

At this time, Mu Yunfan sensed the body of the Black Tiger Demon King, and there was a special aura that spread out, making people feel as if they were facing a terrifying monster.

Not only that, Mu Yunfan also found that there was an extremely strong dangerous aura hidden in the body of this Black Tiger Demon King, just like a terrifying tiger.

This Black Tiger Demon King has a lot of black lines on his body, and Mu Yunfan also found that these black lines are not simple textures, but extremely weird runes.

Although Mu Yunfan had not studied the formation, he could still see one or two clues to this ancient formation.

"This kind of ancient formation, I seem to have seen it somewhere."

Mu Yunfan frowned, and many images suddenly appeared in his mind like lightning, and he finally remembered where he had seen this ancient rune.

"Could it be that this is the formation arranged by the Black Tiger Demon King in the rumored way? This is...... Imprison the Formation! “

Imprison the Formation!

An ancient and strange formation.

This kind of formation, in ancient times, there was once a great master of the formation, who once relied on a confinement formation to forcibly seal all the powerhouses of the entire continent!

It is said that this great master of the formation is the legendary formation master 'Dragon Emperor'!

It is said that the Dragon Emperor has reached the pinnacle of the path of formation, and once sealed the powerhouses of the entire continent with his own strength.

It is said that the Dragon Emperor once used this imprisoning formation to seal a city, so that the tens of millions of people in it could not escape.

It is said that the Dragon Emperor once killed a genius from a continent, and he didn't even set foot in the realm of the spirit fetus.

It is said that once the Dragon Emperor could destroy a star with a single thought.

Mu Yunfan learned about these rumors from some ancient books or books, but they still couldn't be confirmed.

After all, in ancient times, the name of this Dragon Emperor was so loud that almost the entire Southern Wilderness Demon Domain was known to everyone!

"Looks like I'm going to be out of luck today."

Mu Yunfan smiled bitterly, the Black Tiger Demon King in front of him had reached the peak of the spirit fetus realm.

Mu Yunfan thought to himself, he couldn't resist at all.

"Whew!"

"Little bastard, aren't you rampant?"

"Aren't you arrogant?"

"Now, I'll let you try it, the taste of being suppressed by me."

The Black Tiger Demon King roared, and his huge claws slapped down fiercely.

Mu Yunfan's eyes narrowed, and his figure disappeared in place again.

The Black Tiger Demon King's attack failed, but instead of being annoyed, he grinned.

"Haha, little bastard, can you run away?"

The Black Tiger Demon King swung his claws again and grabbed into the air, and then struck out again.

However, when the Black Tiger Demon King grabbed the air again, his face couldn't help but change: "What's the matter, how can this be?" “

Seeing Mu Yunfan reappear, his face also became a little pale, and there were fine beads of sweat on his forehead.

"Little bastard, you're pretty tenacious, but I'll see how long you can run?"

The Black Tiger Demon King roared, and his huge claws swung again.

Mu Yunfan's figure kept dodging, and he didn't forget to cast the Thunder Nine Styles and the Eight Waves of Wind and Fire.

"Roar!"

The Black Tiger Demon King roared again, his huge claws flapping incessantly.

"Boom! Rumble! Rumble! “

Loud voices kept ringing out.

Mu Yunfan's figure retreated again and again, and every time, he dodged the fatal blow of the Black Tiger Demon King.

"Bang bang ......"

Mu Yunfan was constantly dodging, constantly being attacked by the Black Tiger Demon King.

"This guy is so fast!"

"If I were attacked by him, I would definitely be hurt."

Mu Yunfan secretly complained in his heart, he felt that his current body was about to fall apart.

"Little bastard, aren't you awesome?"

"It's kind of you keep hiding!"

"Do you think you can hide?"

The Black Tiger Demon King shouted angrily and kept chasing Mu Yunfan.

And at this moment, the Black Tiger Demon King also noticed those ancient lines on Mu Yunfan's body.

That kind of pattern is the legendary formation pattern.

And in the void beside the Black Tiger Demon King, streams of black mist rolled up.

This is a strange black toxin, this black toxin, as soon as it touches water, immediately turns into a liquid, melts into the void, and then disappears.

And the swamp monsters in the swamp, the moment they sucked this black venom, they exploded one after another, and their flesh and blood flew sideways.

"Little bastard, it seems that I really want to arrest you for research."

"Hehe, worthy of my prey."

The Black Tiger Demon King licked his lips, and his eyes looked extremely excited.

And then, it slapped out with one claw again, heading straight for Mu Yunfan.

"Little bastard, aren't you pretty good?"

"Aren't you arrogant?"

"Aren't you afraid of death?"

"Then you will die!"

The Black Tiger Demon King roared while constantly slapping out his claws, and he wanted to slap Mu Yunfan into a pulp.

However, to his surprise, these claws of his fell on Mu Yunfan's body, as if they had hit cotton, and they had no effect at all.
