Chapter 754

Under Lu En's Observation Haki detection.

He detected an extremely terrifying life force.

Observation Haki covered a radius of three hundred meters...

So.

He had perceived it even earlier than Little Lufei.

The mysterious master of Luffy, Ace, and Sabo!

"Strong!"

"Extremely strong!"

"Such a powerful and vigorous life signature..."

Lu En's eyes grew somewhat deeper...

He had perceived it.

An extremely powerful presence had entered the range of his Observation Haki.

If he wasn't mistaken,

this man must be Luffy's mysterious master.

Nagli, the top-tier powerhouse of the old era!

In addition,

within Lu En's Observation Haki detection, he also sensed two weak life signatures.

They must be Ace and Sabo.

In comparison,

Ace and Sabo's life signatures were like flickering candle flames beside the brilliant halo of a majestic full moon.

No comparison whatsoever!

That man was extremely strong.

To Lu En's perception...

No less than a powerhouse like Doflamingo.

More terrifying than Crocodile's aura.

"An old man possessing such a powerful life signature..."

"Is this, then, the top-tier pirate of the old era?"

"Today truly opened my eyes."

Although Lu En had not yet seen the man in person, his Observation Haki had already revealed everything clearly.

What an incredibly powerful and terrifying presence!

"No wonder he once fought the Pirate King Luo Jie..."

"A man who wields Conqueror's Haki."

"Such a vigorous life signature proves the terrifying strength of this individual."

Lu En thought.

Finally—

His steps came to a sudden halt.

After stopping,

Lu En slowly raised his head.

His eyes, sharp and bright, gazed ahead,

the next second.

He saw an old man.

The old man wore a hat, bit a small pipe between his lips, dressed in plainly ordinary clothes, sitting beside Ace and Sabo like an ordinary elder.

Though the man emitted no aura or pressure whatsoever,

Lu En still felt it.

Within this man's body...

lay an extremely terrifying power.

Should it erupt, it would shatter heaven and earth!

"He is Luffy and Ace's master?"

"The pirate who once fought the Pirate King Luo Jie?"

"The top-tier powerhouse of the old era?"

Lu En silently observed the man.

Meanwhile,

Nagli, seated beside Ace, seemed to sense something and turned to look at Lu En.

In an instant,

their gazes met.

Nagli's wrinkled face, previously as still as a calm lake,

upon seeing Lu En,

stirred with faint ripples.

Only to see

Nagli's eyelids slightly lowered, his eyes filled with seriousness and awe.

"This young man..."

"Is no ordinary person!"
