Infinite Mana In The Oasis

"I wonder how long you last before running out of mana with such an extravagant use. Hehe."

Rog commented and licked his lips with his longer-than-usual tongue. He had concluded that Eren had used a lot more mana than he should have just to stack the spell and increase its potency. He labeled the battlemage as an inexperienced greenhorn who didn't know any better.

"Never interrupt your enemy when he is making a mistake."

Eren said to himself and chuckled before using the same trick again.

Blitz Shard!

Eren stacked the spell many times and created a swarm of lightning shards around him. They surrounded him like bees buzzing around their honeycombs. Ironically, they made the same type of sounds as the bees.

Eren raised his hand and guided some of the shards toward Rog while he retained a large portion of them to bolster his defense.

'Is this guy an idiot? Does he want to just die faster?'

Rog pondered this as he disappeared into thin air before the lightning shards could hit him. He created a safe distance from his opponent once again before casting another spell.

"Hehe. finish him off, Killer!"

Rog had access to the spirit beast spell. Killer was his spirit beast's name, which was a mountain cat with sharp claws and fangs. This mana beast was also known for its speed and mist element. It preferred to take its victim off guard by blending in with the environment the same way Rog was used to handling his kills.

Killer, the mountain-cat-type beast created a hissing-like noise toward Eren before approaching him silently at exceptional speeds. Eren could feel that something dangerous was approaching him even though he could not see it clearly with his eyes.

He just spread his Blitz Shard outward and attacked his incoming enemy in all directions. Another hissing voice followed him when he did that. He turned his back to see that the mountain cat had almost reached the back of his neck. This is when the beast was attacked by loads of Blitz Shards all at once.

Hiss!

The spirit beast hissed and started to manifest clearly in front of Eren. In response, he cast more Blitz Shards around himself to reinforce his defenses before observing what was in front of him.

Rog's spirit beast looked like a normal cat except for the fact that it was three to four times the size. It had three tails that seemed to be six every time it moved them from left to right in a rhythmic fashion.

The beast had white spots all over his body. Its golden eyes shone brightly in the mellow environment of the underground space. Its dark blue fur was already making it difficult for Eren to see it clearly because of its elusive mist element properties.

"What are you looking at, Human?"

The spirit beast named Killer asked Eren, which surprised HIM. The beast's voice was human-like, but it also had a beastly side attached to it. The voice also had a facet of emotion that told him that the spirit beast was dead serious when talking to him.

Eren knew about the spirit beast spell. And the fact that he needed his natal body to have it in his arsenal. However, he wasn't aware that the beast tamed by the spirit beast spell would be able to talk in the human tongue as if it was speaking it from its childhood.

Rog looked at Eren's expressions and found them to be amusing. He canceled his invisibility spell and spoke up.

"You really are a greenhorn. Haha. I guess you don't have a spirit beast of your own. That makes my job easier."

Rog said and chuckled to himself before sighing as if he was deeply saddened by something.

"Killer is a special spirit beast that I obtained after eradicating the merchant caravan that was transporting it. He kills all my prey within a few moments of his appearance.

That's why I rarely let him out. He is the mood killer for my hunting games. Thus, I named him Killer.

Maybe I got too excited by your reckless performance and let the beast out. Your lightning-based attacks won't be too effective on him because of his mana body.

Why not just give up and let me kill…"

Swoosh! Swoosh! Swoosh!

Rog wanted to say more. However, he observed that Eren had made his move. He drew his crossbow from his storage and fired a series of lightning arrows at him. Rog chuckled before changing his position yet again.

Eren kept shooting at Rog while trying to cast his defensive spell. He didn't want to ignore the assassin-like beast while trying to kill the assassin that was his owner.

Blitz Shield

Eren failed to cast the spell this time, and he found out that it was not synchronized properly. Blitz Shard and Blitz Shield were the only spells that had their sync rates not complete a few days ago. He had managed to master Blitz Shard well. However, it seemed that his defensive spell still needed a bit of practice.

Eren felt a sharp pain in his right leg when he recovered from his backlash. The Killer had attacked his right leg with its sharp paws. His mana body had also suffered attacks from his Blitz Shard in the process but he didn't seem to mind them much.

Eren gritted his teeth to deal with the pain before casting his movement spell. It had been cast to cover his legs in lightning. Killer had already changed his position after successfully launching his attack with his right front claw that was now coated in Eren's blood.

"Hahaha. See? I told you resistance is futile. You might as well.."

Swoosh! Swoosh! Swoosh!

Eren fired three more lightning arrows at Rog. This was not to hurt him but to shut him up. For an assassin, the guy sure liked to talk a lot.

Eren cast another swarm of Blitz Shards all around him to increase the density while he was busy shooting Rog. The latter couldn't believe his eyes when he saw Eren casting the same spell to counter his spirit beast.

In its current state, the spell was not effective against Killer. So Eren was compensating for it using quantity.
