Lizarius woke up, and the system announced, "Evolution complete."
Lizarius asked, "System, can I see my rank?"
"You are a Rank 1 Low Tier Beast," the system replied.
Lizarius left the cave and entered the forest. I should go back to where the human corpse is, he thought. A few moments later, he reached the location. He activated his invisibility and climbed a nearby tree. He looked down at the spot where the bodies had been, but they were gone. Only the footprints of wild beasts remained. I'm lucky I left when I did, he thought. Otherwise, I would be dead. He climbed down from the tree and continued into the forest.
A few minutes later, he came across a pond. As he tried to drink, he spotted a black, rat-like beast with blue stripes and a horn on its head. Lizarius immediately turned invisible and asked the system, "What kind of beast is that?"
"Lightning Rat, Rank 1 Low Tier Beast," the system responded. "It can use its horn to gather lightning and attack. They usually move in packs."
But it's alone, Lizarius thought. Maybe there are others nearby. He looked around, but saw no other creatures. His yellow eyes glowed slightly in the dim light. That means it's alone. He slowly moved towards the beast from behind. He tried to bite it, but the rat reacted quickly, dodging the attack. Lizarius became visible again.
The rat, angered by the sudden appearance of a creature larger than itself, charged at Lizarius, its body and horn crackling with lightning. It tried to shock Lizarius with its lightning-covered horn, but the horn couldn't penetrate his scales. Lizarius stared at the rat, his face shadowed, his yellow eyes glowing menacingly. He opened his mouth and bit down on the rat, his teeth sinking into its flesh, drawing blood. The rat struggled, using its lightning attack, but the shock only made Lizarius bite down harder. The rat eventually died.
As Lizarius devoured the rat, the system announced, "You gained 40 points and a Lightning Gene."
"System, what's a gene?" Lizarius asked.
"You can gain the lightning ability from the Lightning Rat's gene," the system explained. "Do you want to fuse the gene?"
"Yes," Lizarius replied. He felt a tingling sensation in his head, and two small white horns with blue tips emerged from his forehead. He tried to use the lightning ability, but only a few weak sparks came out.
"System, why is the lightning weaker than when the rat used it?" Lizarius asked.
"You can use points to strengthen the ability or fuse more Lightning Genes," the system replied.
Lizarius checked his rank. The system displayed: "White Scale Lightning Lizard, Rank 1 Middle Tier Beast."
So, by eating more Lightning Rats, I can evolve this ability, Lizarius thought.
