All of them used their strongest power, and even air currents had formed on their fists.

"Rumble"

A violent tremor sounded in the air.

As for Robin, although she wanted to dodge, their speed was too fast.

Before Robin could move, their fists were already in front of her eyes.

Just as they were about to hit Robin, a violent black lightning burst out from Robin again.

"Crack, Rumble"

After a roar of thunder and lightning, several CP9 agents were instantly blasted away by this force.

It was even more terrifying than the force that blasted Kalifa away just now.

Several people were blasted dozens of meters away and heavily smashed onto the factory equipment.

Lucci, who had not made a move the whole time, frowned as he looked at Robin.

"How powerful is this guy hiding? Is this Nico Robin's Devil Fruit ability?"

Lucci had no idea about this Haki ball, but he could feel that it contained extremely terrifying power. Even if he made a move, his outcome would not be better than the other CP9 agents.

Robin was also stunned. She didn't expect the small ball Ye Yu gave her to hide such terrifying power.

And it would automatically protect her.

The more Ye Yu did this, the less she could let CP9 launch the Buster Call.

Lucci knew that if he made a move, he would end up like the others, so he could only threaten Robin, "Nico Robin, do you want to attract the Buster Call? As the Devil Child, you are qualified for us to launch a Buster Call. We can repeat what happened in Ohara back then."

Lucci mentioned Ohara, and memories of Ohara being destroyed suddenly flooded into Robin's mind, and her face instantly turned much paler.

The destruction of Ohara was a psychological shadow that she could never get rid of.

She didn't want Ye Yu and the others to be wiped out by the Buster Call.

Although Ye Yu had the strength to defeat two Marine Admirals in a row, who knows if the Marines would send out two Admirals at the same time because the target is Ye Yu?

This kind of thing has not not happened before.

The Buster Call that destroyed Ohara before was actually just the most basic standard.

However, the World Government has records of launching Buster Calls with ten times the scale, or even with two Admirals at the same time.

So, being told this by Lucci, Robin yielded.

Just as she was about to put away the Haki ball, a voice came from beside Robin.

"I'd really like to see the legendary Buster Call."

Hearing this voice, Robin was stunned for a moment, then looked to the side.

Ye Yu appeared in front of her.

Robin trembled all over. "Ye Yu, you, how could you?"

Ye Yu smiled faintly, "You've been out for too long. I thought something happened to you."

Although he said that, Ye Yu actually knew about Robin and CP9's conversation long ago.

Let alone Ye Yu being nearby, even if Ye Yu was dozens of kilometers away, as long as he wanted to know the conversation between Robin and the CP9 agents, or even see it, it would be very easy.

His Observation Haki had reached an extremely terrifying level, and for the people of this world, it was even similar to the power of a god.

Robin didn't know how to explain for a moment.

Ye Yu didn't continue to look at Robin, but looked at Lucci, and smiled, "CP9 organization, I heard you want to launch a Buster Call? I've never seen one before. Why don't you give it a try and see if you can kill me?"

Lucci looked at Ye Yu, and he felt immense pressure.

Ye Yu didn't do anything, he just stood there, but it made him feel a lot of pressure.

He even felt a little out of breath.

However, Lucci still forced himself to say, "Ye Yu, don't think you are invincible just because you defeated a few small characters. The Ocean is far more vast than you think."

Lucci's words made Ye Yu want to laugh.

He said faintly, "The Ocean is indeed very vast for you."

Lucci's eyes narrowed slightly, and he was angry. "You're courting death!"

"Soru~"

The next moment, Lucci appeared in front of Ye Yu. Just as he was about to make a move, a terrifying force blasted him away.

"Rumble"

Like a cannonball, he penetrated buildings within hundreds of meters one after another, and finally fell onto the beach by the sea.

At this time, his whole body was bleeding.

Lucci hadn't even seen how Ye Yu made his move before he fell onto the beach.

Where he had traveled, there were already holes.

A ditch dozens of meters long also appeared on the beach, and a pile of soil appeared behind Lucci.

It was because of this soil that he was able to stop.

However, his whole body's bones and muscles were shattered, and it would be very difficult to recover.

He couldn't even turn into his animal form.

Lying in the pit, Lucci said in despair, "Too, too terrifying. That guy is too terrifying."

"No wonder the World Government gave him such a high bounty assessment. This guy's power is simply not something a human should have."

It's not even certain if Ye Yu personally made that last attack.

But the result was that he was beaten into this state.

After dealing with Lucci, Ye Yu looked at Robin.

Under Ye Yu's gaze, Robin lowered her head guiltily.

She didn't know how to face Ye Yu.

"Because they will launch a Buster Call, I'm worried, I'm worried~"

As she spoke, Robin couldn't continue.

She just shed tears.

Ye Yu patted Robin's shoulder, "Alright, let's go back if you're fine."

After saying that, he didn't care about Robin anymore and left by himself.

Robin hesitated for a long time. Seeing Ye Yu's figure about to disappear from sight, Robin gritted her teeth and followed.

Returning to Ye Yu's side, Robin asked, "But CP9 can launch a Buster Call."

Ye Yu said faintly, "Then I'd like to see it."

Robin continued, "But a Buster Call might send out two Admirals at the same time."

Ye Yu smiled, "Whether it's two Admirals or three Admirals, it doesn't matter. Since you are my crew member, a Buster Call is just the Marines conducting a military exercise for us."

Robin had completely not expected Ye Yu to treat the Buster Call so indifferently.

"But a Buster Call will completely wipe out the target. Once a Buster Call is launched, I'm afraid this Water 7 will be destroyed."

Ye Yu shook his head, "No, you'll see. You'll see if they launch a Buster Call. Even if the CP9 agents want to launch a Buster Call, the World Government has to allow it."

"You'll know by watching if the World Government will allow it."

Robin was very confused. "Why do you say that?"

Ye Yu thought for a moment and said, "Do you know why the World Government withdrew our bounties?"

Robin had indeed been unable to figure out what was going on.

Ye Yu thought for a moment and said, "Before coming here just now, I went to see a few people."
