Secondary Nature—Mammoth Home!
Mud Vipers were extremely territorial in nature. Though being Beginner Iron Grade Pranic Beasts, frightened by powerful Pranic Beasts, when their nests get damaged, they charge at the enemy with reckless abandon.
It was why the First Minor Crisis happened, even though Mud Vipers are afraid of Empyrean Tusks the most among all Pranic Beasts.
Bone Vipers were created from them, with their Nest being replaced with the Empyrean Tusk's body. Basically, the Empyrean Tusk was their home, so they would do everything in their power to preserve their home.
And if the slightest harm were to come to their home, they would charge out and target the cause. By harnessing their genetic desire to protect their homes at all costs and by linking it to their Prana, Grehha managed to create their Secondary Nature.
If a Bone Viper were to hatch in the biome of the 1st Empyrean Tusk, then it could consider the 1st Empyrean Tusk its home. It would live, propagate, and die in its home. The effects of its Secondary Nature allowed the Empyrean Tusk to actually treat Bone Vipers as part of its immune system.
In the human body, white blood cells alone don't form the immune system. There are also lymphocytes and many others. All combined form the human body's immune system, with each geared towards fighting different enemies.
At present, in Sumatra Continent, the Empyrean Tusks had one enemy they were awfully geared to face and sustained repeated defeats. That was the Boar King. Grehha had read the end of Sumatra Chronicles.
The strength displayed by the Boar King there was honestly on a whole other level. He was using more than a dozen Internal Inertial Gravity, unleashing earth-shattering might merely through the flaps of his eyelids. There was a slight exaggeration, but only slightly. Even his eyelid flaps generated powerful gusts of wind.
That was how broken he gets towards the endgame. Therefore, Grehha had been thinking about it since his reader days. The Empyrean Tusks sustain significant losses during the Third Major Disaster, which makes them incapable of facing the Boar King in the Fourth Major Disaster.
Moreover, half the Mammoth Clan dies in the Second Major Disaster, causing them to weaken significantly. Therefore, there might be someone to take the place of the Mammoth Clan and fight on its behalf. They should also be able to help the Empyrean Tusks recover from damage and get back on track as soon as possible.
The answer Grehha arrived at was the Bone Viper.
Back when Grehha arrived at Inala's house and knew the latter had chosen to become a Zinger, he was honestly relieved. Because, both had opted for swarm tactics, which seemed to be the only realistic option to counter the Boar King.
Inala focused on offence through his Zingers while Grehha focused on defence through his Bone Vipers. The actions of both would strengthen the Mammoth Clan as a whole, making their losses minimal.
After the merger, Minor Crises were no longer as dangerous to the Mammoth Clan. Except for a select few that were similar to the 5th Minor Crisis, all other Minor Crises could be resisted with minimal losses.
But Major Disasters happen in the terrain influenced by the Major Treasures. These areas were dangerous to even the Mystic Grade Pranic Beasts. Therefore, there was a significant chance their losses would be as severe, if not even higher this time.
After all, Grehha feared what Virala and Blola might do, since they were destructively greedy characters. It was no longer possible to put them to death for good without killing Blola.
But Grehha would never get an opportunity for that, since even Raaha didn't support that line of thought, for Blola's existence was tremendously useful for the Mammoth Clan. Just the fact that he could create Parute King Fruits was of significant importance.
And as long as Blola was alive, he could revive the other reincarnates. Therefore, the only other option available to Grehha would be to strengthen the Mammoth Clan as much as possible.
Genetic modification for reptiles in endangered habitats was part of Grehha's job back on Earth. Through that, he tried to protect countless endangered reptile species, adapt them to different environments, and increase their numbers through selective breeding.
He focused on his strength here and remained focused on that single task all along, never wavering. Though their interaction was minimal and only lasted a year, Grehha knew how terrifying Inala's intelligence was.
He knew with a guarantee that Inala would be boosting Gannala's abilities like crazy. When she returns to the Mammoth Clan, she will easily take up the spot as the strongest. Grehha was confident about that, and based on how Orakha behaved after getting revived, treating Inala with the utmost caution, he had confirmed his thoughts.
As the two constructively greedy individuals of the seven, it was up to them to ensure the Mammoth Clan's fate in this timeline was better than Sumatra Chronicles.
"And the final Nature is the best." Grehha smiled, 'I need to thank Resha for this. Though it was a trade, he gave me the Toxin Refinement Skill and a bunch of Skills devised to take advantage of the characteristics of Mud Vipers.'
Tertiary Nature—Digester!
Mud Vipers produce toxins capable of softening the Mud Balls they shoot out. These toxins could even melt through other substances, though a bit lacking in efficiency. The prime goal of this toxin was to soften the target enough for their consumption.
Grehha improved upon that aspect to create the Tertiary Nature, through which the Bone Viper could gather and prepare resources. By mixing the secreted toxins into the resources, they'll soften it and transform it into a sludge that could be digested easily by the Empyrean Tusk.
That was the Tertiary Nature's function. Basically, through it, Empyrean Tusks could digest everything faster and replenish their strength rapidly.
The Bone Vipers could flood out of the Empyrean Tusk's body when necessary, consume everything in their path, and store in their stomachs after mixing them with their toxins. Then, they would return to the Empyrean Tusk's stomach biome and barf out everything.
This barfed substance would be easily digestible for the Empyrean Tusk. In situations similar to their current state of being, Bone Vipers would be of tremendous use.
Adding them to the Empyrean Tusk wouldn't strain the resources generated in its body. Rather, the Bone Vipers could actively participate in the resource collection. It was this reason that caused the Mammoth Elders to face an identity crisis.
However, after a moment of thought, they calmed down, understanding that they—Mammoth Clansmen—wouldn't be replaced, since the upper end of the fighting strength still depended on them.
And unlike the Bone Vipers, they were sentient beings, capable of a variety of things, including birthing new Empyrean Tusks.
"Chief," One of the Mammoth Elders stared at Raaha and frowned, "You made us argue needlessly."
"Had you told us about the Bone Vipers' Secondary Nature, we would have accepted it without raising a fuss." He continued, "They too would worship our Deity. So, they align with our beliefs."
"Let's vote." The Mammoth Elder raised his hand, "Do we introduce Bone Vipers in the bodies of our Deities?"
There was a unanimous acceptance as everyone raised their hands in response, causing Grehha to heave a deep breath in relief. 'Thank goodness.'
Raaha observed Grehha's expression and fell deep in thought, 'It seems there's more to this than I thought.'
'As expected, I need to meet up with Inala and Gannala.'
