[ Ding! Aura Mastery tiered up to Tier One! ]

[ —Masteries—

—Aura Mastery—

—Tier One—

—Proficiency: 1/100

—Increases the aura skills' power by 500%

—Increases the efficiency of aura by 5% ]

'Efficiency…' Slime#47 wondered, then asked Elder Slime, "Elder, what does it mean by efficiency?"

Old Slime replied plainly, "When we use aura, we don't use it properly. Like if Acid Fist requires 10 wisps of aura, we pour in 15 wisps, wasting 5 for the same level of power."

"Ho… I see," Young Slime nodded.

"And control over aura increases. Very powerful beings whose mere presence could destroy a world don't even harm the grass on the ground while battling….It is because of this. You can control whether your aura damages the area or not…" Old Slime explained.

"I see… so it is the same with mana mastery?" Slime#47 questioned.

"Yes, it is… and smoke tends to appear when you attack with magic spells, right?" Elder Slime asked playfully with a small smile.

"Yes, it always does," Young Slime replied with a grin, as it had helped him a lot in his battles.

"It is due to lack of control over mana," Old Slime said. "And not only that—with control over reserves, the aftermath of battle can also be controlled."

"It is very helpful then," Slime#47 muttered.

Not only would it take less mana or aura to use skills, but he still remembered the slimes almost being blown far away when he fought with Aqua Crocodile.

If he controlled aura and mana, which would let him control the aftermath in the end, it would help him a lot.

'I have to get Mana Meditation next and tier up Mana Mastery,' he decided his next goal after getting Lightning Slime.

"By the way, you can stack masteries for power, but only one will work for energy reduction," Old Slime said without blinking.

"What… yeah… I understand. Energy usage cannot be zero," Young Slime said, clicking his tongue, because he could have turned energy zero after thousands of loops by stacking multiple masteries, but it seemed impossible.

Elder Slime explained, seeing Slime#47's annoyance, "You see, masteries don't actually reduce energy usage. They make you refined in energy control. When you use a fist skill with Fist Mastery, you automatically use the correct energy requirement involuntarily…"

He gave an example after a pause: "Acid Fist requires 10 wisps. You, who would normally use 15, would only use 14 after getting Fist Mastery; The higher the mastery, the more efficient the control."

He blacked out as he evolved.

After a few hours, he checked himself in the trough.

'Not bad…' He praised his own cuteness. He was just the size of a regular slime.

Unlike a regular slime, he had a light-purple body, and he found it sweet, having grown used to seeing adorable blue slimes every day.

He wasted no time and opened the class evolution section.

'Blue Lightning… so it's blue for all next‑level elements…' He mused with a wide grin. He could not hold back his laughter. "Hahaha."

The joy of succeeding after more than twenty loops made him insanely happy.

"Lightning Body, Blue Lightning." He used the skill combo that had lived in his mind and kept him going.

ZZZ!

His body transformed into an element of light purple lightning. The next second, purple changed to blue, and sparks emitted from his body.

Zap!

"Whoa!" he muttered, as his speed was off the charts.

Thud! After just a few seconds, he fell to the ground.

"Yeah… this combo burns too much mana," he muttered as he backed out, while grinning out loud.

----

"Lightning Body, Blue Lightning." Slime#47 turned into blue lightning as he zipped through the slime farm owner's chest, turning him into a crisp, scorched corpse!

Thud!

He landed and turned back to normal, while—Thud!—the scorched body fell to the floor, smoke rising from the corpse.

----

"We thank you," the Oakfield villagers knelt and thanked their savior.

Young Slime repeated what he did in the 24th timeline, saving Oakfield villagers by killing all the guards and donating Bailiff's crystals.

[ Ding! You have gained a new title—Oakfield Village Saviour {Common}! ]

'Here it comes…' He still remembered the wisp of faith he would gain from this title.

Last time, his trait Eternal Mastery had eaten it. Now he did not want to miss it again, so he clicked on Title and on Faith Info for a new window to pop up, but—

[ Ding! Trait—Eternal Mastery {Mythic} has devoured the wisp of faith! ]

'What…' He scowled in fury, clenching his fists.

"It's okay… It's okay…there will be many loops….I'll see how many times it can devour," he muttered, calming down.

----

[ Ding! You have killed Aqua Crocodile! ]

"It was a very easy fight…" he grinned. Last time, he had felt it was tough due to being a Fire Slime. Now, he was Lightning Slime. Just with Lightning Ball and other lightning skills, he killed it.

He did not even need to use his trump combo.

He glanced at the notification and remembered the small details he had asked Elder Slime.

---

"Elder Slime, why am I not getting exp from killing?" Young Slime questioned doubtfully.

Old Slime answered flatly, "You will only get EXP if the one you kill has a level higher than you; someone same level as you, or just three levels lower than you. If not, no EXP."

Hearing that, Slime#47's eyes twitched.

"What did you expect? It's for the world's benefit. Think about it—if a level-100 wanted to level up, he could slaughter hundreds of level-10 people with no risk, and the world would end by an extinction." Elder Slime's words made Young Slime nod, despite feeling a little pity.

Then Old Slime continued with a smile, "Even fighting a similar level or just three levels lower is very challenging, as they are almost equal in power. No one wants to risk their life in battle… this is why our world isn't flooded with powerhouses."

----

"There it is…" Elder Slime muttered as he glanced at the sealed door.
