There were several other miscellaneous rules but only the move three mentioned were of utmost importance for Feng Mei and his grand plan.
The first rule of the contract was the most important one.
The first rule will bound these soul workers to him or his trusted aide side. Why is this rule the most important one? It's because through the use of this rule Feng Mei will keep these soul workers under the dark.
Under the dark about Divine source and their shards!
Feng already knew that these three soul workers are greedy bastards. What happens when greedy bastards find a treasure greater than half-divine? They willfully sacrifice their lives to obtain it!
In the case of soul workers, this rule was ten times more amplified. It's probably because they don't have an actual physical life or something along the descending line, so when they come across a treasure of great importance they will do everything to obtain it.
For greedy soul workers, treasures were of utmost importance. Obtaining treasure was more important than their lives. So, they won't blink their eyes, before the sacrifice. What's better is the fact that they don't die so they usually fight with their lives on the line. Yeah, soul workers don't die even after they are killed? Why? Because they partially don't exist, but they can be annihilated by the power of greater existence.
Greater existence such as divine beings can annihilate soul workers by the use of greater power. For example, Feng divine energy or the Soul-devouring creature Soul devouring ability can be used to permanently kill the three retards in front of Feng.
But annihilating them from existence itself or even killing them will alert the Underworld. Something Feng doesn't want to happen.
He wanted to obtain all the divine sources that the soul-devouring creature has, but if the underworld power official descends then they won't let him have it easy.
In a sense, Underworld decision of sensing only three soul workers with a very powerful soul capturing treasure worked in the favor of Feng Mei. These three soul workers didn't hold a candle against Feng, and he can keep them under the dark about the divine source. Seven days later, he is bound to annihilate the soul-devouring creature, as Theone will be able to bring back more than ten shards of divinity, and with the use of the art of Divination, Feng will locate the place the Soul-devouring creature is residing in.
He just needed to bound the three soul workers to certain rules, so that they won't come in contract with the divine source or their divine shards, and he had done just that!
The soul workers will be living with him for seven days a week, there's blind to be some mishaps though it will be better if there aren't any. He had a lot of skills, abilities, and spells that shouldn't be exposed to anyone in the underworld as it will attract unwanted attention towards himself.
Something Feng, who was treading the line between the two lives didn't want.
Yeah, Feng was considering what life he should choose. The two choices he has is,
A: The life of a galactical conquer!
B: The life of an otaku.
Both lives are good and have their perks and cons, and he couldn't make a decision as such choices can only be made through the passage of time and life.
Though, the unwanted attention of the underworld officials was certainly not something good in both life, hence the reason why Feng didn't want them to expose what they see about him.
But if they don't expose anything about him then it is bound to raise the suspicion of the officials of the underworld!
Hence, the third and the last most important of the big three rules came into play.
This rule allowed them to expose some things about Feng. Those things are the information that Feng wants them to expose.
How heroic he is!
How handsome he is!
How great he is!
How powerful he is!
How selfless he is!
What a good man he is!
A selfish, arrogant, and prideful narcissist being praised like this will certainly smile. Such praise is bound to give rise to a smile on their faces.
Just thinking about it, Feng's lips thinned into a creepy smile that scared the shit out of the three soul workers, especially Kang Su.
It's because the Tainted human had the same smile on his face when he was whipping their asses with chains made out of Divine energy!
"Bam, Why is the tainted mortal smiling?" Tael said while flinching like a scared rabbit.
"Tael, how would I know? Maybe he is planning to whip it again." Bam replied while shaking his head and taking cover behind Kang Su, the big one of the three soul workers.
On the other hand, Kang Su pulled out his treasures and handed them over to Feng Mei.
"My lord, whatever you are about to do, just don't include me in it. These are all the treasures that I have collected over the course of my life, a total of 5000 years, from jade lake dragon amulet to southern lava archdemon saliva, all is in there, including the sword of King Arthur, the cape of batman, and the underwear of superman."
'What bullshit is he spewing?' Feng didn't understand what the reasons behind his and the other soul workers' obnoxious actions were, and he didn't care.
For some reason, when it comes to certain things, Feng acts denser than a braindead hamster.
"Whatever, I will gladly accept your offering!" And so he said that with a wider smile.
With a happy smile, he happily accepted everything that Kang Su has given him.
Seeing his sadist smile become wider and wider, Ban and Tael almost pissed themselves in fear.
Thankfully, their race was called soul workers for a reason. They didn't have a physical body, and lacked many, actually make it all, components that make up a human body.
Their gender couldn't be defined as they didn't have a D. So a special way was used to define the gender of a soul worker. The way was mysterious and only the higher-ups of the underworld knew that.
Heck, even Feng who had reached the Truth level didn't know how their gender was defined. That just shows how much secretive the underworld is about this knowledge.
Bam and Tael were certain that the tainted mortal is planning on how to torture them. They also understood that the only way to escape this torture was to follow in the footsteps of their experienced and shameless brother. Their brother was no one except the soul worker who is named Kang Su.
Naturally, the soul workers didn't mare with other soul workers to produce more soul workers. So, how could they have siblings?
Well, it's also a mystery to the world, but Feng knows the knowledge behind this mystery. At the age of one, soul workers are assigned to a team. The team members are classified as brothers and sisters while the teacher assigned to teach them the way of the soul worker is classified as the father or the mother depending on their gender.
Anyways, Tael and Bam also took everything out of their deep pockets and gave them to Feng who was still cracking up because of the third rule of the contract.
"Tainted Mor–" Smack* "My lord, please accept these offerings. These are our hard-earned money working as soul workers for the past 1000 years, we aren't as old as Kang Su and don't have much treasure, but this much underworld currency can be used for one hundred messages by the number one beauty of the Qunhuqa Brothel. My lord, whatever you are planning to do, just don't include us in it!"
"Has the world gone crazy today or is it just these three, but whatever it is, it is good for me as for me it is raining money. Who said that money can't rain?" While thinking that, FENG HAPPily accepted the things these soul workers had given him.
The things that the soul workers had pulled out of their underwear and handed over to Feng Mei was a pouch, a pouch that was stinking with a baleful aura.
Feng opened the pouch and noticed that insides of it are tens of thousands of glittering underworld black core gems. Black core gems are a currency of the underworld and could be used for. many purposes.
One of the main purpose of it was to summon Goblins. Not the goblins of an Rpg world, but a Korean goblin!
