"Then let's begin!"
Inside the casino,
Ren smiled as he and Tsunade each sat down in front of a slot machine.
"Just to confirm—no ninjutsu allowed," Tsunade said again.
She looked at Ren suspiciously.
Seeing how confident he was made her strangely nervous.
"Like I said, no ninjutsu. Let's start."
Ren shrugged.
But just as the two were about to begin—
someone approached them.
It was a ninja wiping sweat from his forehead, walking over with obvious hesitation.
His strength was around the Special Jonin level.
Not outstanding, but certainly not weak.
More importantly—
he was a sensory-type ninja.
Since Ren and Tsunade entered the casino, he had been watching them.
But the immense chakra contained within Tsunade's body had already made him break into a cold sweat.
As for Ren—
after two years of training, he could now perfectly conceal his chakra aura using the ability of the Forest-Forest Fruit to merge with nature.
Unless he used high-level ninjutsu, even Karin's increasingly refined Kagura Mind's Eye wouldn't be able to detect him.
Which meant that during the incident at the inn's hot spring, Karin's warning had been unnecessary.
If he truly wanted to do something, she wouldn't notice at all.
Moreover—
after intense training, his Eternal Mangekyō Sharingan had grown stronger.
His control over the ocular technique Ōanamuchi had reached a new level.
If he stayed inside the Netherworld Space, ordinary Byakugan, Sharingan, or common sensory abilities would not be able to detect him.
Only extremely pure Byakugan, Mangekyō-level ocular techniques, or sage-level sensory abilities might possibly detect him there.
"My lord…"
The casino owner hurried over after hearing the report.
He brought along the ninja hired to guard the casino.
Both of them looked extremely nervous as they approached Tsunade respectfully.
"Alright, I understand what you're worried about."
Tsunade waved her hand dismissively.
"I know casino rules. I won't break them."
"You should recognize her, right?"
Ren smiled and spoke to them.
"One of the Legendary Sannin. The Princess of Konoha—Tsunade-hime."
"Also known as… the Legendary Sucker."
"The Legendary Sucker?"
The sensory ninja and casino owner widened their eyes.
Then their faces lit up with joy.
"Of course! Of course!"
Tsunade's reputation in casinos was extremely reliable.
Rumor had it that although she was incredibly powerful, she never cheated with ninjutsu and never refused to pay her debts.
And not only did she lose every gamble, she was also extremely rich.
Wherever she went, casinos made enormous profits.
Thus—
she had earned the nickname "Legendary Sucker."
Her legendary gambling record was widely known throughout the industry.
"You two can stay here and watch," Ren added with a smile.
"That way no one can say I cheated."
He turned to the sensory ninja.
"Go ahead and inspect these slot machines. See if there's any problem."
"That won't be necessary," the casino owner quickly said.
"We trust Lady Tsunade's reputation."
"Good."
Tsunade nodded proudly, lifting her chin.
She shot Ren a confident look.
"…"
Ren clicked his tongue.
"First round—start!"
"Ding… ding…"
The two inserted coins.
The slot machines immediately began spinning rapidly.
"Ding!"
Tsunade's machine stopped first.
All different symbols.
No reward.
She lost.
But Tsunade—
as well as the casino owner and the guarding ninja—
all widened their eyes in shock.
Because Ren's machine slowly stopped spinning.
And displayed three large symbols:
777
A super jackpot.
"WHAT?!"
Not only Tsunade—
even the casino owner's eyes nearly popped out.
"Clatter! Clatter!"
Coins poured endlessly from the machine.
A massive pile quickly formed, with many spilling onto the floor.
The surrounding gamblers were stunned.
Even players at other tables turned to stare.
"Three sevens?"
"A jackpot?!"
"You've got to be kidding!"
"Did that guy cheat?!"
"I've played here forever and never even gotten three matching symbols!"
"And he hits triple sevens?!"
Soon,
a large crowd of gamblers gathered around.
Meanwhile, Ren looked at the stunned Tsunade and smiled.
"Tsunade-nee, that's the first round for me."
"Now let's go to the second round."
Before he could continue,
the casino owner hurriedly interrupted.
"Wait a moment, sir!"
"This machine has run out of coins. Could you use another one?"
He quickly checked the machine.
Finding nothing wrong, he looked at the Special Jonin guarding the place.
The ninja shook his head.
"A coincidence?"
The casino owner had no choice but to accept the loss.
Still suspicious, he kept his eyes fixed on Ren.
Ren calmly moved to another slot machine.
The owner gathered the jackpot coins into baskets.
"You're pretty lucky," Tsunade muttered.
She didn't believe he could keep hitting jackpots.
Still annoyed after losing the first round,
she deliberately switched to another machine.
"Second round… start!"
"Ding… ding…"
The symbols spun again.
"Come on… come on…" Tsunade clenched her fists, staring intensely at the screen.
"Ding!"
Her machine stopped.
Again—
all different symbols.
Not even a consolation prize.
Her coins were gone.
Annoyed, she turned to look at Ren.
"What?!"
"Another triple seven?!"
"Impossible!"
"No way he cheated!"
"He only inserted a coin and pressed start!"
The entire crowd exploded in shock.
The casino owner was completely dumbfounded.
He looked at the Special Jonin standing behind Ren.
But the ninja had sensed no chakra fluctuations whatsoever.
And Ren hadn't performed any suspicious movements.
"That's the second round, Tsunade-nee."
Ren winked at her.
He tossed a coin to the Special Jonin.
"Inspect it."
The ninja carefully checked the machine.
"No problems."
He even inspected the next machine Ren would use.
Still nothing unusual.
"When luck arrives, you can't stop it."
Ren smiled.
"Alright, Tsunade-nee, let's continue."
"Hmph! It's only the second round!"
"You're definitely going to lose!"
Tsunade refused to believe it.
She had been watching him closely.
He really hadn't cheated.
Then—
Round four.
Round five.
Round six.
All the way to round ten.
"Ding—Ding—"
Under Tsunade's stunned gaze,
the tenth machine once again displayed:
777
Coins poured out in torrents.
The gamblers around them were breathing heavily.
Their eyes turned red with greed.
They nearly rushed forward to grab the mountains of coins.
Several large baskets beside Ren were already overflowing with tokens.
"All triple sevens…"
The casino owner's lips trembled.
His face turned pale.
He felt like he was about to have a heart attack.
His heart hurt.
His liver hurt.
Everything hurt.
"Does a gambling god really exist?"
The Special Jonin muttered blankly.
Looking at the young Ren with pure reverence—
as if staring at a deity.
With his sensory abilities, he was confident that even the Kage of the Five Great Villages wouldn't be able to cheat without him noticing.
Yet he sensed nothing.
Ren had even cooperated fully.
Switching machines.
Switching coins.
For the last few rounds—
he didn't even touch the machine.
The ninja himself operated it.
Either Ren's power was unimaginably terrifying—
or his luck was absurd.
But judging by his young age…
it had to be luck.
"Boss, cash out."
Tsunade had completely lost interest.
She had been utterly crushed.
Ren leaned toward her ear with a smile.
"Tsunade-nee… a bet is a bet."
He couldn't help thinking—
If he had been an ordinary civilian or low-level ninja,
he could've followed Tsunade around to casinos every day.
By simply betting the opposite of her choices, he could easily become a billionaire.
Of course—
that was only if Tsunade didn't punch him to death first.
"Hmph! When have I ever refused to pay a bet?"
Tsunade snorted angrily.
Her beautiful face flushed red.
It wasn't her fault.
This had clearly been a guaranteed victory—
yet she still lost completely.
But from now on—
she would never fall for Ren's tricks again.
No matter what he said.
This…
was absolutely the last time.
