Infinite Mana In The Oasis

An infinite mana core.

Eren immediately recognized the nature of his second mana core which was located in the same ethereal space as his first mana core. For some reason, he felt more connected to the infinite mana core than the first one.

While his first mana core had an affinity to lightning, his second mana core didn't seem to have any elemental affinity. As per Eren's knowledge, this had to be impossible because every mana core was born with its wielder's affinity.

This mana core was the same size as his first one. It was also made of Rank 1 mana and was in a gaseous state like the first one. The infinite mana core was like a copy of his first mana core except for the fact that it always kept spinning, never reducing its rotation speed.

'This…'

Eren had realized that this was the answer to all the demands the pantheon of infinities had granted him. If he were to consider that the first mana core originally belonged to the previous Eren, then this mana core was something that was completely his.

Infinite mana core responded to Eren's will. It pumped so much mana into his mana circuits that he felt overwhelmed by it. His tongue had the taste of coconut because he was so full of mana all of a sudden.

Jayce and Ralph had thought that Eren had run out of miracles when he was on his knees and about to die. They had already started to think about how to dispose of the body and cover the incident. This is so that their usage of the artifact doesn't get noticed by the Elysian city's authorities.

But it seemed that Eren still had some tricks up his sleeve. The duo watched with incredulous expressions as Stan was sent into the air a second time because of Eren.

They then observed that Eren had a second breakthrough in the same rank. They both looked at each other with puzzled expressions as if asking if what they were seeing and feeling was true or a dream.

This time, nobody between them offered to take care of Stan who was thrown a few meters away from them. Because they saw that Eren was covered in lightning that was even more intense than their previous appearance.

'Wasn't… wasn't he out of mana just now? Did he consume a potion or something?'

As Jayce watched Eren with vigilant eyes, he suspected the involvement of some potion. Ralph had the same doubt.

"Jayce, if it's one artifact or many, it won't matter. So we might as well draw our weapons and take care of this problem from its roots."

Ralph said hoarsely. He didn't wait for his friend's answer though. He clenched his fists hard before summoning his spear. Jayce followed his cue without saying a word– drawing a runic hammer.

The first thing Eren did after he tapped into the infinite mana core was cast healing spells that he had stopped casting because of their inefficiency. This time, he didn't care about how much mana the spell consumed and was all out.

The tongues of lightning that Jayce and Ralph were seeing dancing on Eren's body with such flashy details were the effects of the healing spell.

Blitz Heal.

This was the spell's name Eren had received from his digested memories. He could cast it effortlessly because the spell was less complex than the movement spell.

The lightning-element healing spell repaired Eren's fractures. First, it stopped the bleeding from his wounds as the lightning streaks danced around them. The new skin and epidermis started appearing over the wounds as if a clip from one of those time-lapse videos played at super-speed.

One had to know that Blitz Heal was not as effective as this. It was only because Eren provided the spell with no limits that it had been running in overdrive.

Crack. Crack. Crack.

Eren's bones started making noises as their fractures healed, enabling him to stand up once again. All the while, he was looking down. So he took a long breath and looked at his weapon-equipped opponents.

Jayce and Ralph saw Eren looking at them with a very peculiar smile on his face. His eyes looked at them like they were the ideal targets for his experiments.

Blitz Steps.

Strike first. Strike hard. No mercy.

Instead of waiting for his opponents to make a move, Eren had decided to take things into his own hands. He cast his movement spell that he felt he must have cast a thousand times now. He had started to understand the nuances behind the spell the more he was using it. And he had started to tweak the spell as per his needs.

Eren had learned from his past mistakes. Instead of focusing on Jayce who had an earth-element affinity, he approached Ralph first. The guy was prepared for Eren's attack, if only barely. But he was still taken off guard because of how Eren had used his movement spell.

Eren simply enhanced his movement spell by increasing its mana consumption- not caring about the efficiency. Normally, movement spells are among the most mana-efficient spells because they need to be maintained for a long time. But Eren had stopped caring about the mana expenditure as soon as he was made aware of what was available to him.

Grab. Twist. Snatch.

Erne first caught Ralph's arm by his wrist and twisted it with all his might. He had also employed his mana to invade his victim's body. The guy received the stun effect of the lightning mana after experiencing severe pain in his wrist.

Before he could retaliate, Eren had already snatched his weapon from him. The weapon was bound to Ralph because of the runes. So he couldn't imbue it with his mana yet. But that didn't stop him from using the weapon in brute style.

"Aaaaaaargh!"

Ralph's eyes turned red in the next moment as he felt a sharp pain in his right leg. He looked down to see his weapon had been driven between his right leg. Eren had lodged the spear blade straight through his fibula and tibia bone.

Before Ralph could shout some more to relieve his pain, a lightning-powered fist kissed his chin from below with tremendous kinetic force. Due to that force, he closed his jaw abruptly, causing him to cut off his tongue cleanly.

Ralph's teeth shattered before poking through his cheeks as his jaw closed with tremendous force. It was as if the fragments of his teeth had suddenly decided to show off by being out in the open.

Suffice to say Ralph was done for.
