"You're revived at the perfect time." Yennda stared in silence for a few seconds before breaking into a smile, "It's done."
"You'll die soon."
"What…are you talking about?" Grehha frowned in confusion before he noticed a droplet of blood on the floor. He lifted his foot and noticed a thin needle lodged into the floor that had pricked him.
It had been coated with a powerful anaesthetic that he didn't even realise had pierced his feet. A glance at it and he understood what had happened, "I see, you intend to kill me through a disease."
"But I don't intend to die." Grehha shrugged and raised his hands, opening one of them to reveal a nail-sized green sphere, "So, can't you do something about it?"
Yennda stared at the green sphere before realising what it was, "That's your…Empyrean Incubator?"
"What of it?"
"I'm not talking about it." Grehha grinned and walked towards Yennda, "Look inside it. What do you see?"
"There seems to be something inside…?" Yennda focused intently, noticing a small dot-shaped object within the Empyrean Incubator. "What is that?"
"Did you attend science classes on Earth?" Grehha asked.
"I did," Yennda nodded, "But you better talk fast. Otherwise, I won't hesitate to accelerate the progression of the infection in your body. It's something I created to be effectively potent only on you."
"This is a human ovum." Grehha grinned, "Yarsha Zahara's to be exact. Do you know what this means?"
"You…you're deranged!" Yennda stumbled back a few steps in shock, "Are you being serious now?"
"Why wouldn't I be?" Grehha laughed, "I purposefully made the sack explode to disorient her focus and senses. And when I hugged her, I used the Empyrean Incubator to extract one of her ova."
"Is this why you…never had a girlfriend in the Mammoth Clan?" Yennda felt revulsed, "Even I'm finding it hard to stomach."
"My goals have always been consistent from the very beginning." Grehha whistled as he walked to a corner of the room, "Now, if you'll give me some privacy."
"Are you mad? You're doing it here?" Yennda shouted, "You think artificial insemination is a joke?"
"In-vitro fertilisation, that's the correct term for it." Grehha corrected. "Besides, I did it for a living on Earth, for reptiles, but it's not all that different for humans."
"Whatever the fuck it's called, do you want to go about it in this way?" Yennda asked, "Just think of what the child will think in the future…"
"She will never have to worry about anything. Unlike you, I'll be a damn competent father." Grehha waved his hand casually, "Now, if you excuse me. I have some serious work to do."
"Even if you succeed," Yennda shouted, "How are you planning to send the child to the Mammoth Clan?"
"It'll be alright," Grehha laughed, "I have been going through Yarsha's memories all along. I'm sure Gannala is in hiding somewhere in this Kingdom."
"I'll summon her once I'm done." Grehha arrived at a corner and asked Yennda, "Now, can you stop the infection? I need to concentrate. I don't wish to waste time curing myself."
Grehha didn't know exactly what Yennda had done to him and hence decided that it was better to appeal to the latter instead of trying to find a cure.
"I can't," Yennda shrugged, "I've simply added impurities in your blood that'll clog up your Spirit Container. It'll explode after a while. My abilities cannot reverse it, since Yarsha has enough of it stored in her."
"If you wish to stay alive longer, treat it yourself." Yennda snorted, "Aren't you the capable one?"
"It's done," Grehha coughed up some turbid blood and began his work. Since Yennda explained the cause and workings, it was easy for Grehha to figure out a solution.
He simply applied his Empyrean Incubator on his heart and used it as a filter to extract the impurities that intended to clot his Spirit Container. He shrunk the Empyrean Incubator while it carried the impurities, ripped it apart from his heart, and safely brought it out through his food pipe.
Empyrean Incubators appeared to patch up the holes as his Prana surged into the region better and healed the injuries. He had Silver Grade strength, which was enough to make a full recovery in less than a minute.
He understood his body the best and had enough control over his Natures to perfectly execute the task once the underlying principle behind the infection was discovered.
'He made that look like it was child's play.' Yennda thought and didn't bother with Grehha anymore, instead focusing on his objective.
"It's done." Less than a minute later, there was an exclaim from the other corner of the room.
"Already?" Yennda turned around in shock and noticed Grehha's exhilarated face, "It has barely been a minute."
"Did you think I was cranking my lizard or something?" Grehha laughed, "I simply extracted the healthiest sperm from my nut through an Empyrean Incubator. All I had to do was insert the sperm in the ovum."
Primary Nature—Spirit Bone!
Grehha unleashed bone mist and condensed a tiny figurine that resembled an Empyrean Tusk.
The Empyrean Tusk figurine opened its mouth and unleashed a soft cry, inaudible to even the ears of Yennda who was standing in proximity. Grehha placed the Empyrean Incubator—
containing Yarsha's ovum that had been fertilised by his sperm
—in the figurine's stomach.
Upon inspecting the figurine, Grehha kept it in a corner and watched in patience.
"What are you planning?" Yennda frowned, "Yarsha will be arriving any moment now. Her work hours are starting."
"Not today," Grehha grinned, "She needs some time to gather her bearings after I weirded her out."
"And…look, it seems Orakha is also lying in wait," Grehha muttered upon seeing a Mystic Eater stealthily emerge from the floor and stare around. It paused for a moment after spotting Yennda and Grehha but swallowed the figurine and retreated into the ground.
A few minutes later, it appeared again and spat a Bone Slip in his direction. Grehha grabbed it and inspected its contents, smiling upon seeing the message from Gannala.
[I've received the ovum. I'll nurture it with all my effort. Your proposed plan is decent. We'll take action when the time is right. Collaborate with Yennda as you see fit.]
"That's what she says." Grehha stared at Yennda and muttered once the latter too accessed the contents of the Bone Slip. He recorded his reply on the Bone Slip and threw it to the Mystic Eater.
The Mystic Eater swallowed the Bone Slip and perfectly erased all traces of its existence as it made its exit. There was no sign of a hole forming there at all. And somehow, it made its way to the laboratory while passing through the walls of the castle, able to avoid all of Yarsha Zahara's traps.
"How did you make them avoid alerting her?" Yennda frowned, "Honestly, there were plenty of methods used here. And a good portion of them were created using my power, and it shouldn't have been easy to counter each of them, not to mention all of them."
"That's thanks to you." Grehha laughed, "I've gone through all the details you've fed Yarsha Zahara. Honestly, your information is extremely precise and impressive, to the extent they don't realise you're purposefully glossing over key points while giving wrong clues."
"It's a keystone trap!"
A keystone trap was one in which the entirety of a building—of facts—was weaved in such a way that the perceiver of the information remains ignorant of only the keystone. And by analysing the building's structure, they'd form a wrong impression, which would cause the keystone they form to collapse the building spectacularly.
The riskiest aspect of using a keystone trap was that it only worked against the most intelligent people. And Yarsha Zahara definitely fell under this category. The same went true for Brangara too, which was why both had detailed information about the Mammoth Clan but were absolutely wrong about foundational facts.
One such fact was the Mystic Seven being able to enter the Mystic Grade, when in truth, it's their daughters who'll enter the Mystic Grade, and that too by evolving according to the experiences of their parents.
Therefore, even if the Mystic Seven failed to kill Brangara, every single daughter of them would have evolved to counter the Celestial Boar and Yarsha Zahara. That aspect was what made the seven Mystic Paths absolutely terrifying.
Yennda had done the same for practically every technology from Earth that he had introduced to Yarsha Zahara. All of them seemed perfect in her perspective but had absolutely glaring flaws in the eyes of Yennda.
"And because of your keystone trap, Yarsha Zahara doesn't understand the true essence of what makes your power so terrifying." Grehha muttered, "A bio-war is the most disgusting shit we humans on Earth have come up with, topping even nukes."
"I'm not anything that special." Yennda rolled his eyes and asked, "Your explanation only states how you can detect flaws in her defensive arrangements. But how did Gannala figure it out?"
"I don't know," Grehha shrugged, "She has Orakha on her side. He's good at such stuff, considering he plays with Mystic Eaters and Human Avatar modification all the time."
"You can ask him for an answer once we're out of this place."
"Alright, so what's your plan?" Yennda stared at Grehha, "It seems Gannala has given you her approval."
"About that…" Grehha smiled wryly, "My job was already done once I sent that ovum to Gannala. Now, I only need to be used by Yarsha Zahara to strengthen the quality of Wean Clansmen being birthed in the upcoming months."
"Other than that, I'll be assisting you in whatever you need." Grehha grinned, "We'll make our escape only when you're ready and there are a few Wean Clansmen babies to steal."
"Assisting me is the plan…?" Yennda frowned, "What about your growth? Don't you have plans to take advantage of Yarsha Zahara or Brangara's powers to upgrade yours?"
"I literally have everything I need." Grehha grinned as he pointed at himself, "My current power system is exactly what I had in mind for the endgame."
"That's…it?" Yennda tilted his head in exasperation, "Brother, I don't mean to be rude. But,"
"That's fucking weak!"
