Inside a rather upscale detached villa, the table was covered with brand new bills, and Kakuzu stood there, starting to count the money one bill at a time.

At this moment, a staff member came in carrying a black machine device and said to Kakuzu, "Mr. Kakuzu, there's a money counter here..."

Kakuzu refused the staff without lifting his head:

"No, machines can easily malfunction, using my naked eye to observe is more convenient for work. Moreover..."

He paused here, making everyone in the room tense up.

Kakuzu picked up a stack of bills, placed it in front of everyone and said, "These twenty bills are counterfeit, replace them immediately."

His emerald green eyes seemed to be glowing.

He didn't know if someone deliberately placed counterfeit bills inside, or if someone carelessly put them in, but as long as he was present, counterfeit bills could not slip through unnoticed.

"Quick, go replace them!"

The male owner of the villa immediately ordered the staff to replace the bills.

"Yes!"

With that said, the staff ran out of the room to the vault to prepare anew.

Kakuzu ignored these people and continued counting the money as if no one else was around.

It wasn't until two hours later, after carefully counting three times, that he stopped with satisfaction.

Placing the bills into a prepared black leather suitcase, it fit just right.

"Mr. Kakuzu, is everything okay now?"

The male owner rubbed his hands and asked ingratiatingly.

"There's no problem, the numbers match."

Kakuzu glanced at the man.

"About the IOU..."

The male owner smiled obsequiously.

Kakuzu took a card with the Shion Flower emblem out of his pocket.

It was the IOU mentioned by the villa owner.

It noted the loan amount, the date and interest, as well as the repayment date and amount, all clearly specified.

"Remember to repay sooner next time, if the overdue repayments continue, it will be difficult for me."

"Absolutely, absolutely."

The male owner took the IOU from Kakuzu and looked painfully at the black suitcase in Kakuzu's hand, a heavy weight relieving from his heart.

"Then, let's take our leave, hoping not to visit you next time."

Kakuzu carried the black suitcase and opened the villa door; outside, the garden had turned into a wasteland.

Numerous black-clothed bodyguards lay scattered around, moaning and lamenting.

The work of a debt collector isn't glamorous.

Those targeted by debt collectors naturally are untrustworthy individuals who have overdue debts.

No matter how good the villa owner's attitude seemed, once targeted by a debt collector, it meant they had failed to repay debts within the stipulated time.

This villa owner appeared ingratiating, but he was in fact one of the wealthiest individuals in this town, with businesses involving gambling and brothels—activities of a black nature, practically ruling over the area.

Confronted by such a character, ordinary debt collectors must weigh their options carefully.

But for Kakuzu, it really wasn't a challenging task.

The villa owner was so compliant because Kakuzu demonstrated his strength as a debt collector, which compelled him to repay obediently.

To deal with such debtors, one must use some special means to successfully recover debts.

This is the work of the Shion Flower Merchants Association's debt collectors in the Land of Demons.

Having strong combat power is a key criterion for joining the debt collector organization.

The struggles between debt collectors and debtors will continue indefinitely.

Leaving the villa, Kakuzu, carrying the black suitcase, took out a small booklet from his pocket.

The booklet recorded numerous names of untrustworthy debtors, along with their addresses and other information.

"The next target, in the Land of Valleys..."

Having resolved matters here, setting sights on the next target, Kakuzu felt he didn't have much time to rest.

Over-resting would only lower the efficiency of his work.

On his black coat, hung a pure silver badge engraved with the Shion Flower pattern.

It represented his grade as a debt collector.

He was an exceedingly rare Silver Debt Collector; in the debt collector organization, his level was considered top-notch.

In less than three years, he became a Silver Debt Collector under the Shion Flower Merchants Association, a frighteningly swift advancement.

To date, within the debt collector organization, none have matched his speed of promotion.

With a 100% debt recovery success rate, working year-round at high intensity, he was a model existence for all debt collectors.

The Undead—Kakuzu.

As Kakuzu walked out of town, having dealt with the debtors here, he headed towards the next target's location—the Land of Valleys.

A small country consisting mainly of valleys.

Kakuzu had visited there a few times in the past when performing bounty missions.

Not long after leaving town, an uncharacteristic breeze brushed past him, causing Kakuzu to instinctively pause.

Sweeping his gaze forward, five figures stood obstructing his path.

Kakuzu spoke in a rather surprised tone: "It's been a while, familiar faces indeed, didn't expect to encounter you here."

Standing before him were the Nokizaru Group.

Affiliated with a special action team of the Land of Demons military, mingling in the Ninja Realm's Underground Black Market, maintaining close connections with dignitaries and merchants of various countries, they were dubbed 'the ninjas who hunt ninjas'.
