The iron cage slammed open and terrifying air waves burst everywhere.

Mei was blown away by the air waves and landed a hundred meters away.

"This is the feeling of freedom! Twenty years! I am finally free again!"

The giant ox's expression is full of joy, and his delighted look is not only ugly, but also somewhat terrifying.

Mei frowned slightly, 'Why did I feel something is wrong?'

"Giant ox, I have already lifted the seal according to our agreement. Now, you also need to fulfill your promise and hand over the Fuinjutsu to me."

At this moment, the giant ox the giant Niu set his sights on Mei again.

It's just that at this time, his expression is not full of sincerity like before. Instead, there is a hint of ridicule on his expression.

"Stupid human, do you really think that I will give you the Fuinjutsu? Actually, I don't even know where it was located. But, even if I know, I won't give it to you. It is because of that damn thing that I was sealed here all this time!"

Mei looked angry and roared: "You lied to me?"

"Hahaha, lied to you? Aren't you humans the best at cheating? Hahaha! Human! Since you let me out, I will send you to hell. No need to thank me, this is what I should do!"

After the giant ox finished talking, he rushes towards Mei.

His huge body, like a big mountain, directly charges into Mei's location.

Mei's pupils shrank, 'If this attack hit me, I am afraid that all of the bones inside my body will be broken.'

'What a terrifying attack power!'

"Iron Hoof Trample!"

Mei repeatedly retreat and trying to get out of here first.

There is not much space in this place. If she fights with this giant ox here, this place will likely collapse.

The size of the giant ox is very large, and his skin is very thick. So he naturally not afraid buried in this place, but if Mei is buried inside, she will die.

Therefore, her first priority now is to find a suitable place to fight against this giant ox.

"Human! You can't run away!"

Seeing Mei tries to retreat, the giant ox runs towards her. After all, he didn't plan to let Mei escape.

"Damn it! Didn't the summoned beasts usually keep their promise? What is wrong with this giant ox!"

Mei cursed as she ran.

The reason why Mei believes in the giant ox is because there is a consensus in the Shinobi World that summoned beasts are very committed to keep their promises.

However, she did not expect that this giant ox is actually not the same as normal summoned beasts.

"Savage Collision!"

The giant ox rushes again and crashing into Mei.

Mei moved her feet and quickly moved away, so the giant ox directly hit the rock wall.

With a bang, a deep pit directly formed on the stone wall.

The huge movement made Mei stunned. After all, this kind of power is above her imagination.

"How can he still have this kind of strength after being sealed for so long? He is not a Bijuu!"

Mei muttered, but didn't think much.

Soon, Mei came to the place where she had come in before.

"Damn it! Where is the exit? Why is it still the same as before?"

There are three stone walls surrounding her, and there is no exit at all!

"Human, you can't find your exit? Then this place will become your grave!"

The giant ox came from the back and couldn't help but sneer when he saw Mei was looking for an exit.

Mei's expression becomes solemn. 'Since I can't get out, it looks like I can only deal with this giant ox here first.'

"Oh? Looking at your appearance, it seems that you're not afraid of me."

Seeing Terumi Mei's calm and solemn appearance, the giant ox was quite surprised.

Mei smiled lightly and said, "Although you are indeed strong, you are still not my opponent at all."

"Humph! Arrogant!"

The giant ox is furious when he heard that, and then he stopped talking nonsense.

"Savage Shock!"

The giant ox speed suddenly increased, and he crashed into Mei again!

The giant ox was covered by blue chakra visible to the naked eye, and the entire cave was shaking.

"Not good, an attack of this level will surely collapse the cave!"

Mei was anxious, and quickly formed hand seals.

"Water Release: Water Dragon Bullet Technique!"

Mei has high mastery in Water Release Ninjutsu. So, even if she is in a place where there is no water, she can still release a very strong Water Release Ninjutsu.

The water dragon roared and rushed towards the giant ox!

"Hmph, such insignificant ability. With my body, how can this kind of weak Ninjutsu do anything to me! Break!"

The giant ox uses his two horns to rush towards the water dragon, and directly destroyed the water dragon!

"What a terrifying defense! It looks like that horn is really hard."

Mei did not have too much time to express her emotions, as the giant ox's horns soon rushed towards her.

Without hesitation, Mei retreat again.

Boom!

The giant ox crashes into the stone wall. At this time, the cave that had been shaking began to collapse.

Pieces of boulders start falling from above.

'It's bad!'

Terumi Mei secretly thought, as she saw a huge boulder fell towards her from above.

At this moment, loud bird's chirp suddenly sounded!

It sounds like thousands of birds are singing!

Mei was overjoyed, and in the next second, a silver-white figure appeared above Mei.

"Chidori!"

The blue lighting scattered everywhere, and the boulder within the radius of three meters is directly crushed and turned into countless pebbles.

Kakashi took Mei into his arms and dodged the other boulder.

"Stupid woman, you sure dare to open seal like that."

Kakashi said quite angrily.

Mei didn't mind Kakashi's tone at all and instead she said playfully: "What's wrong with that, it's just a giant ox."

"You sure are really confident." Kakashi smiled bitterly.

"If I don't have this much confidence, how can I dare to say that I want to bring new life to Kirigakure?"

"Well, that's reasonable. Let's go out first, this place won't last long."

Kakashi didn't want to argue with Mei right now. After all, it is more important to leave this place first.

Mei nodded and said: "How did you come in?"

"Naturally, I come by jumping directly. There is Genjutsu on the entrance hole. The hole is not big, but it is still there."

Kakashi pointed to a small hole at the distance, the hole is just big enough for one person.

"So it's like that."

Mei suddenly realizes, 'So the reason why I can't find it is that hole, this place is too dark, and also that hole is too small.

Mei did not look carefully before. That's why she could not find it.

But Kakashi is different. The Genjutsu on the hole is useless against him.

"Damn human! Another one came unexpectedly."

The giant ox snorted and rushed over directly.

Kakashi didn't talk nonsense when he saw this. The blue lightning appeared again on his right hand, and he smashed the small hole directly!

Boom!

A flash of lightning flashed, and two figures that were mixed with some gravel, emerged from the ground.

The two of them just fell not far away as the ground suddenly arched and starts to split apart!

Seeing this, Kakashi quickly retreated while holding Mei.

Boom!

The huge body of the giant ox drilled directly out of the ground!
