I run a casino in the immortal realm.

Ye Tianqiong took the jade slip and probed it with his divine sense.

"what?"

Ye Tianqiong let out a soft exclamation, a hint of surprise flashing in his previously nonchalant eyes.

The jade slip did not record any profound techniques, but rather a set of extremely concise symbols and a rigorous logic presented after their arrangement and combination.

"Simplified numbers... Multiplication table..."

Ye Tianqiong muttered to himself, a meaningful smile playing on his lips.

As the vice sect leader of the Heavenly Demon Sect, although he didn't manage the accounts much, he was well aware of how troublesome the sect's vast and chaotic resource allocation was.

The Heavenly Demon Sect's intelligence system had already relayed information about the tax reform storm orchestrated by the Xuantian Sect.

What interested the higher-ups in the demonic path the most was this peculiar accounting method known as "simplified numbers".

In fact, some astute merchants in some peripheral vassal sects and black markets under the Heavenly Demon Sect have already begun to secretly imitate and use this number.

This is one of the reasons why Ye Tianqiong risked his life to personally infiltrate the heart of the Xuantian Sect.

He had thought it was just a lucky find from some mathematical master, but he never expected that it was all the work of this young man who was only in the mid-Foundation Establishment stage.

"That's interesting."

Ye Tianqiong accepted the jade slip, and his gaze towards Zheng Yifei held a hint of genuine appreciation: "I will accept this set of materials. Within half a month, I will have someone memorize them thoroughly."

"Then I wish the Heavenly Demon Sect abundant wealth."

Zheng Yifei smiled slightly and cupped his hands in greeting.

"I will come to pick you up in six months."

Ye Tianqiong stood up, his black robes billowing behind him without wind: "At that time, you will return to the Heavenly Demon Sect with me to personally oversee the installation of the printing press, the distribution of the newspaper, and the initial operation of the super gambling den."

If you do well, I'll guarantee you can roam freely in the demonic path; if you dare to play tricks...

Ye Tianqiong didn't continue speaking, but just snorted coldly.

The next moment, his body suddenly transformed into a thick cloud of black mist, dissipating into the air like a phantom, leaving not even a trace of spatial fluctuation.

If it weren't for the still-warm jade cup on the table, it would be as if he had never been there at all.

As soon as Ye Tianqiong left, the terrifying pressure that had enveloped the villa instantly dissipated.

"thump!"

Xu Zhengkun could no longer hold on. His legs gave way, and he collapsed onto the armchair, panting heavily.

He, the dignified sect leader of Qingyun Sect and a cultivator in the early stage of Golden Core, had his back completely soaked with cold sweat, as if he had just been pulled out of the water.

"You're insane... Yifei, you're absolutely insane!"

Xu Zhengkun pointed at Zheng Yifei with trembling hands, his voice filled with undisguised fear and panic: "That's the vice sect master of the Heavenly Demon Sect! A great demon in the late Nascent Soul stage! How dare you bargain with him and make him swear an oath to the Heavenly Dao?"

Do you know that if he so much as casts a single thought, we would both be reduced to ashes today?

Zheng Yifei stepped forward, personally poured Xu Zhengkun a cup of hot tea, and handed it to him, his expression unusually calm: "Brother Kun, fortune favors the bold. The more obsequious you are in front of such an important person, the more he will think you are just a piece of trash he can manipulate at will."

Only by demonstrating irreplaceable value and daring to make demands will he truly consider you a collaborator.

"A collaborator? That's like seeking a tiger's skin!"

Xu Zhengkun gulped down a mouthful of hot tea, using the warmth to suppress the turmoil in his heart. He roared in a low voice, "Do you know what we're doing? Colluding with the demonic path! This is an unforgivable crime in the cultivation world!"

Once discovered by the Xuan Tian Sect's Enforcement Hall, not only will the mirage be forgotten, but the entire Qing Yun Sect, numbering in the tens of thousands, will be branded as traitors, their entire clans exterminated, with no chance of surrender!

Seeing Xu Zhengkun's terrified expression, Zheng Yifei pulled up a chair and sat down, a calm smile playing on his lips.

"Brother Kun, do you think the Xuan Tian Sect will let us off the hook just because we don't collude with the demonic path?"

Zheng Yifei's eyes turned deep and cold: "You know better than I what kind of person Elder Qin Cang is. He is only holding back now because the sect leader is in seclusion and he doesn't dare to cause any trouble."

Once the sect leader fails to break through, he will definitely devour the mirage, this tempting prize.

Xu Zhengkun was stunned, and his hand holding the teacup tightened slightly.

He knew Zheng Yifei was telling the truth, but the risk of colluding with the Heavenly Demon Sect still made him feel suffocated.

"Moreover, Brother Kun, you only saw the risks, but you didn't see that this was a flawless way to break the deadlock."

Zheng Yifei leaned forward slightly, his eyes flashing with a chillingly intelligent light: "This isn't just about finding a backer, but also about completely solidifying the identity of 'Xu Zhengyun' and perfectly extricating the Qingyun Sect from this vortex!"

"Take it off? How do you take it off?"

Xu Zhengkun was completely bewildered.

"Six months later, I went to the Heavenly Demon Sect with Ye Tianqiong."

Zheng Yifei interlaced his fingers, his tone calm yet every word thunderous: "At that time, the Heavenly Demon Sect will spread the word that the Qingyun Sect's tax commissioner, Zheng Yifei, who was killed by the robber cultivator back then, actually didn't die at all. Instead, he was secretly kidnapped by experts from the Heavenly Demon Sect because he displayed extremely rare business talent, and his death was staged."

Xu Zhengkun's eyes widened, and his breathing became rapid, as if he had grasped something.

Zheng Yifei continued, "In recent years, under the severe torture and coercion of the Heavenly Demon Sect, 'Zheng Yifei' has helped the Heavenly Demon Sect by making printing presses, publishing newspapers, and setting up a super gambling den to amass wealth for the Heavenly Demon Sect."

"hiss--"

Xu Zhengkun gasped, his scalp tingling, and his gaze toward Zheng Yifei was filled with disbelief and shock.

This scheme is too ruthless! It's absolutely brilliant!

"In this way, the logic is completely closed."

Zheng Yifei sneered: "From the outside, even the higher-ups of your Qingyun Sect have been deceived by the Tianmo Sect."

Even if the Grand Elder of the Xuantian Sect was furious, he could only blame the Tianmo Sect; he would never suspect the Qingyun Sect of colluding with external enemies.

"More importantly..."

A chilling killing intent flashed in Zheng Yifei's eyes: "The Hu family and Qin Cang have always wanted to investigate Xu Zhengyun's background. Once this news gets out, the Hu family will know that their enemy, Zheng Yifei, whom they have wanted to kill day and night, is not only alive but has also become a guest of honor of the Heavenly Demon Sect and is under the protection of a late-stage Nascent Soul expert."

Even if Hu Lie had ten times the courage, would he dare to seek revenge in the heart of the Heavenly Demon Sect? He could only swallow his anger! He certainly wouldn't suspect that Xu Zhengyun was Zheng Yifei.

Xu Zhengkun was thrilled to hear this. His original fear and worry vanished, replaced by a wild joy of escaping a desperate situation.

"Wonderful! Absolutely wonderful!"

Xu Zhengkun slapped his thigh and stood up excitedly: "With this one move, we not only cleared the Qingyun Sect of suspicion, but also completely severed the Hu family's revenge line, and even gave us a way out in the demonic path!"

"So, Brother Kun, we must produce one hundred printing presses in the next six months. This is not only a pledge of allegiance to the Heavenly Demon Sect, but also the capital for my future foothold in the demonic path."

"Don't worry, leave this to me!"

Xu Zhengkun was now completely convinced and patted his chest, guaranteeing, "I'll arrange it personally, and it won't arouse any suspicion!"
