For My Sister, I Became the World Boss

"Tread."

In the silent underground castle, there were slight footsteps.

Under the pervasive damp mist, three figures could be vaguely seen walking towards this side.

"boom!"

Suddenly, a hot ball of fire flew out of the mist,

Killing the bloody bats in the air changed into experience.

The figures of Bai Yu and the other three came out of the mist and gradually became clear.

"This underground castle is like a maze, we won't get lost, right?"

Su Yin held the staff, looked around carefully, and said nervously.

It has been almost half an hour since they entered the underground castle.

However, the BOSS has never been found.

It seems to be going around in circles.

Bai Yu has been using telepathy to observe his surroundings.

Although the structure of this castle is very complicated.

However, every path is under his perception.

Bai Yu knew very well in his heart,

They are not lost.

Just because the castle area is too big,

Moreover, the surrounding walls and buildings are very similar, which will give people the illusion of getting lost.

Under the leadership of Bai Yu,

The two women turned into fighting machines without emotion, killing all the monsters encountered on the way.

Through one after another complicated underground passages,

Finally, he succeeded in coming to an ancient stone gate.

"It's finally here, is it here?"

Looking up at the quaint stone gate in front of him, Su Yin said out of breath.

The stone gate is about ten meters high, engraved with mysterious graphic characters, exuding a trace of ancient atmosphere.

While the two women looked at Shimen,

Bai Yu's "line of sight" has already seen the scene behind through this stone door.

It was an unusually wide space, surrounded by thousands of seats on the high platforms around the circular open space, like a Colosseum.

In the innermost position of the Colosseum, a pale monster exuding black air was gnawing on something.

suddenly,

It raised its head, looked back at the stone gate behind it,

The dark and strange eyes stared straight at Bai Yu's "line of sight".

"Roar!!"

The monster roared suddenly,

He got up and threw the dim spar in his hand to the ground, picked up the thick white bone next to him, and rushed towards the stone gate.

"Boom! Boom! Boom!"

There was a violent sound from the ground, and the whole bunker seemed to tremble.

Outside the stone gate.

The faces of the two women changed.

"boom!!"

Almost at the same time, a huge bang sounded.

The stone gate shattered instantly, flying sand and rocks, and a strong energy shock flooded the entire underground passage.

Bai Yu grabbed Su Yin who was almost blown away, narrowed his eyes, and stared straight at the monster boss.

Fallen evil spirit, level lv60.

"Roar!!"

The fallen evil spirit roared at Bai Yu and the others, frantically waving the white bone in his hand,

The entire underground passage crumbled under its bombardment.

Bai Yu and the others dodged to find the right opportunity to rush into the Colosseum, and the surrounding space suddenly became wider.

"Damn it, that ugly monster actually wanted to crush us to death in the tunnel, it's unforgivable!"

Su Yin chanted the spell quickly, starting with the fourth-level magic,

The strangling array formed by the blue wind blade immediately enveloped the boss.

"Chi Chi Chi Chi Chi Chi!!!"

There was a sharp cutting sound.

However,

The fallen evil ghost was like a copper-skinned iron bone. It was under the wind blade, and it made a crisp sound, but it didn't suffer any harm.

Those sharp wind blades didn't even leave a trace on its body.

"How can it be?"

Su Yin's eyes widened immediately, and he looked at the boss in disbelief.

That is fourth-order magic!

Su Yin continued to cast magic without giving up, and Bai Yu and Jiang Xinyan also attacked.

It turns out,

Except for Jiang Xinyan's sword energy, neither Bai Yu's nor Su Yin's magic attacks worked.

Forbidden physique? !

Seeing this scene, this thought suddenly flashed in Bai Yu's mind.

Not only him, Jiang Xinyan and Su Yin obviously also thought of this.

The faces of the two women suddenly became a little ugly.

There were only three people in the team, but encountering such a rare boss with a magic-forbidden physique was equivalent to losing the combat power of two mages in an instant!

To verify this.

Bai Yu immediately cast high-level magic.

The energy in his body surged wildly, and he chanted a mantra quickly, and suddenly there were streaks of fiery red aura around him, constantly revolving around him.

Seeing this, Su Yin was slightly taken aback, then immediately guessed Bai Yu's intentions, his face froze, and he also started to cast high-level magic.

Jiang Xinyan took on the important task of dragging out the boss.

After a few seconds.

A dazzling red magic circle floated under Bai Yu's feet,

The next moment, Bai Yu waved his staff in the direction of the boss.

A huge magic circle suddenly appeared at its location,

The moisture in the air evaporated extremely quickly, and the entire space seemed to be distorted due to the high temperature.

next moment,

A strong flame explosion suddenly sounded.

Tier 5 Magic: Explosive Meteor!

"Boom! Boom! Boom! Boom!"

Continuous flame explosions sounded, and the hot breath swept the audience and filled the entire space.

Immediately afterwards,

A strong tornado swept out, engulfing the heat wave in the air, and immediately formed a flame tornado that soared into the sky, sealing the boss firmly inside.

Tier 5 Magic · Gale Tornado!

"Whoosh."

Jiang Xinyan quickly retreated to the back,

Feeling the scorching wind in front of him, he stared intently at the boss inside the flame tornado.

"Roar!!"

A roar came from inside.

It wasn't until the flame tornado was finally extinguished that the fallen evil spirit was revealed.

All over the body, on the pale skin, there were large areas of burning marks.

Before Su Yin's face showed joy,

The boss suddenly opened his eyes, waved the white bone in his hand, and rushed out.

That dragon spirit and tiger fierce look doesn't look like he has been seriously injured.

"boom!!"

Facing the savage collision of the boss, Su Yin couldn't dodge in time. He was knocked out by the attacking air wave and hit the stone pillar heavily, and a mouthful of blood immediately spewed out from his mouth.

His face was pale.

"Su Yin!"

Jiang Xinyan's face changed slightly. Seeing that the boss turned to look in Su Yin's direction, she immediately summoned thorns and vines to wrap the boss tightly.

"Xinyan, let's withdraw first. This boss has a forbidden magic physique, and the three of us alone can't deal with it."

Su Yin took advantage of the opportunity of the boss being restrained, and ran over clutching his arms.

Obviously, in the impact just now, she had already suffered serious injuries.

When Jiang Xinyan heard this, she also looked at the fallen evil spirit with a solemn expression, her eyes flickering constantly.

Based on her alone...

If you want to defeat this boss, your odds are very low.

"Roar!"

at this time,

The BOSS broke free and charged again like a bull. The ground was broken along the way, leaving dents visible to the naked eye.

Jiang Xinyan and Su Yin stepped aside.

at the same time,

Jiang Xinyan also made a decision in her heart.

"retreat!"
