"Weak?" Grehha chuckled immediately at Yennda's response, "Guess you're not great at geography."
"Man, would it kill you to explain something without mocking me every single time?" Yennda said as veins popped all over his forehead, "Even I'll get pissed eventually."
"Well, that's not my intention, so ignore it, will you?" Grehha waved his hand casually and asked, "Can you hold your breath underwater?"
"For a short duration, yes." Yennda nodded.
"But can you live underwater like a fish?" Grehha asked next, continuing upon seeing Yennda shake his head, "What about at depths surpassing a dozen kilometres where the water pressure alone is strong enough to crush your body, or places with no light or in absolute freezing temperatures?"
"I obviously cannot live there, unless I were to seriously consider adapting to the place." Yennda said.
"With your powers, it's indeed possible to adapt, but in the process, you might even lose all your Natures if your adaptation results in too strong of a change that causes a race change." Grehha said, "Every single living being faces the same. They have inherent advantages and disadvantages."
"Even the Celestial Boar isn't as invincible underwater as he is on land. Then," Grehha grinned, "What if I can change the terrain as I please?"
"The Chief's power does exactly that." Yennda rolled his eyes.
"Ignore pure terrain for the time being and consider from the perspective of an Empyrean Tusk." Grehha asked, "Which element or substance gives the greatest advantage to the Mammoth Clan, especially the Empyrean Tusks?"
"Bone," Yennda figured out the answer quickly.
"Yes, with it, we'll have an infinite ammo to fight our wars." Grehha said, "Empyrean Tusks will be able to recover their exoskeletons rapidly even if portions of it gets punched off by the Celestial Boar. This will allow them to maintain their battle states for longer durations."
"Think about it a little," Grehha said, "I pretty much showed you the process just now."
"You…" Yennda muttered in shock as he stared at Grehha's groin, "You'll be birthing Bone Vipers en masse?"
"I can do so from any combination of humans and Mud Vipers to form new variants." Grehha winked, "So, it's not impossible to erect entire regions created solely out of bone. I simply need to create enough Bone Vipers at the start and leave them to their devices. As Iron Grade Pranic Beasts, they'll propagate rapidly as long as we protect them during their initial population expansion phase."
"If you're able to bring them here…" Yennda immediately understood what Grehha intended, "That's amazing."
"I'm not one to fight my battles head-on," Grehha grinned, "So, from the very beginning, this was my plan. Even if Brangara kills the Bone Vipers, nothing changes. The entire terrain becomes an absolute weapon for Resha. He'll practically be invincible there."
"And I had planned this build based on the Sumatra Chronicles version of Resha." Grehha chuckled, "His current version is many times stronger."
"Bone Vipers…" Yennda iterated the name once again. It was born with all three Natures. Hence, Brangara couldn't consume it to gain its Nature. This made them the perfect army, especially considering their territorial nature.
As long as Grehha creates them to associate the Varahan Empire as their home, they'll do everything in their power to destroy the invaders, which in this case became the Wean Clansmen and Free Humans part of the Empire.
Moreover, Grehha could even release the Silver Grade versions of Bone Vipers to truly endanger the Varahan Empire. The longer they live and propagate, the greater the quantity of bone accumulated in the region.
This would make it absolutely easy for a Mammoth Clansmen to fight in the region, as anyone with a high level of expertise with Mystic Bone Art could control bone fluidly as a Spirit Weapon.
Empyrean Tusks were on a whole other level of being able to control bone, which was pretty much on par with a Nature. And standing head and shoulders above them was Resha, one whose child was guaranteed to enter the Mystic Grade.
If Gannala and Harrala manage to enter the Mystic Grade in the future, they'll be an absolute menace in all regions with bone, enjoying home ground advantage.
"Then, you will never reveal yourself out in the open?" Yennda asked, "Are you content living in a room for your entire life?"
"Living in a room?" Grehha laughed, "Isn't the Mammoth Clan nomadic in nature? Through the Clan, I can travel to all exotic places of Sumatra in the comfort of my home. That's pretty much luxury of the highest order. I simply need to endure for a century until Brangara is dead."
'Besides, I can continue to evolve endlessly by injecting Empyrean Tusk essence into myself. It's just a matter of time before my Primary Nature harmonises with my Secondary and Tertiary Natures.' He thought.
His Tertiary Nature of Empyrean Incubator was created through Gannala's ovum. His Secondary Nature was Internal Inertial Gravity was also gained through Gannala's blood. His Primary Nature was from the Mud Viper that he evolved into an Empyrean Viper.
From the day he obtained his Natures to his current self, Grehha had been using his Empyrean Incubator to inject Empyrean Tusk essence into himself. His Fragment Disease was cured once he obtained Internal Inertial Gravity.
And now, after subjecting himself to the Empyrean Incubator's effects, Grehha's Fragment Disease had progressed to a significant level. If he didn't possess Internal Inertial Gravity, he would be dead in an instant, unable to handle the pressure exerted by his lungs on his ribcage.
Mammoth Clansmen with the Fragment Disease were more Mammoth Clansmen than humans. The current Grehha's genetic information was almost on the verge of entering the realm of an Empyrean Tusk.
When this happens, his Primary Nature will upgrade to the Gold Grade, which will evolve the race of the Pranic Beast he had fused with. The product will be a Viper with all the characteristics of an Empyrean Tusk.
Moreover, it is from then on that Grehha will be able to truly unleash the power of his build. Originally, he didn't intend to change his current build, which was already endgame material.
But as things continued to change, with the appearance of the Celestial Boar, Royal Zinger, etc. he gained a lot of ideas. And now that he pretty much accessed the entirety of Yarsha Zahara's data, from her childhood to every Skill and ability she had conceptualised, created, and practiced to even her Sumatra Chronicles self, Grehha had better ideas.
Of them, he copied one aspect, which was Brangara's harmonisation of his three Natures to unleash a unified effect.
Grehha's Secondary and Tertiary Natures were already on that path and his accumulations also pointed him in the same direction. He just had better material to finalise the results.
At the end of the day, his abilities won't be changing from his current self. They'll simply become more potent and efficient. "In my case, I simply need time to accumulate my gains. I already gained whatever I would have needed from Yarsha Zahara's memories. Now, I just have to experiment on them to gain more abilities."
"So that's why you said you'll assist me fully." Yennda nodded and grinned, "I understand now. Things will indeed become easier for me once I have your help."
He then extended his hand, "Can you give me a copy of her data?"
"I can give you a copy of data related to the Skills, Cultivation Techniques, and Spirit Weapons that she has knowledge of, but I won't give you anything related to her personal life. Those are my intellectual property." Grehha said with an adamant expression, loosening up immediately after, "But I can give you all the details about Brangara."
"Anything's fine by me. I'm more interested in his powers anyway." Yennda said and received the Bone Slip, returning it to Grehha once he absorbed its contents.
While Grehha destroyed the Bone Slip and focused on erasing all evidences, Yennda focused on comprehending the data related to Brangara—that Yarsha Zahara had knowledge of.
"She screwed up big time," Yennda grinned.
"Not if you hadn't taken the initiative." Grehha was sincere in his praise, "Otherwise, I would have never gained consciously while trapped in that revival sack."
The duo turned silent once Yennda twirled his index finger, signalling that Yarsha Zahara was arriving. Having been under her control, he was able to sense the faint increase in the exertion of her will upon him when she got closer to him.
Even Yarsha Zahara didn't know the difference, but considering how weak and defenceless to her will Yennda was, he could perceive it through experience. Having died enough times, his body was extremely sensitive in terms of senses.
After all, the human body uses all its power in the face of death in order to survive. It would push itself to a breaking point just to survive another day. Yennda had been through that situation too many times that using the entirety of his body's potential was second nature to him.
As his Fragment Disease was never cured, his body was always in a risk of death. This only made him extremely sensitive to everything that could hurt him. In a sense, his weakness was his strength.
The moment he sensed her approach, he signalled Grehha to keep quiet, ensuring that she wouldn't be able to pry upon their conversation.
The door to the laboratory opened as Yarsha Zahara entered, glancing at Grehha as she felt a headache, exercising her will to prevent him from hugging her, feeling a growing desire from him, "Can't you control yourself for a moment?"
"This is me when I'm controlling myself." Grehha stated without a change in expression, nudging Yennda to speak, "This retard might have told you enough about me. So…"
Lust oozed out of his eyes to the levels of insanity, "What do you think of my proposition?"
"You can get everything you need to win this war from me. My information will be your trump card. Heck, I know what you wish to achieve through me. I can confidently promise to casually exceed that level of performance." Grehha winked, "All I ask in return is payment for my hard work,"
"In hugs."
