The change in his attributes was nothing short of earth-shattering. From an all-C baseline, he had suddenly leapt to an all-B level—a tenfold difference between the two ranks.
In truth, this astonishing rise in stats wasn't from Tesla's Spirit Base at all, but rather thanks to the purple reward's assortment of ability cards.
Tesla's Spirit Base wasn't particularly adept at attributes like Strength, Agility, or Endurance. The only real change brought by it was the newly added B-rank Mana entry.
Mana was a special energy of the Type-Moon world, but after the system's optimization, it became a highly versatile, universal form of power.
Where elemental force failed, Honkai energy triumphed.
For Sol Mercer, Mana now filled that role just as well—it could substitute almost any form of energy to fuel abilities from across worlds.
At B-rank strength and quantity, his Mana was comparable to Diluc from Teyvat.
Without a doubt, Diluc's energy reserves already stood at the very peak beneath the Archons.
Reaching A-rank meant power on par with an adeptus, enough that a Caster-class with A-rank Mana would only fall slightly short of a true adeptus—nearly equal.
Of course, while the Mana attribute mattered, Tesla's Spirit Base offered far greater gifts: his innate skills and devastating Noble Phantasm.
[Electrodynamics A: Converts bioelectricity and Mana interchangeably. Certain energy attacks can be absorbed and converted into energy. Massively boosts control over electrical abilities.]
[Genius Wisdom A–EX: Humanity's highest form of intellect. Aside from innate gifts or physical abilities, any skill can quickly reach A–B level proficiency.]
[Pioneer of the Stars EX: Recognition from the planetary will itself, granting the ability to pioneer new worlds.]
[System Keraunos EX – Legend of Mankind, Advent of Lightning: A top-tier Noble Phantasm. With human wisdom alone, re-enacts Zeus's thunder upon the earth. Power sufficient to annihilate an entire city's population.]
"[Electrodynamics A], [Genius Wisdom A–EX], and [Pioneer of the Stars EX]… with these, I can fully develop my abilities. I've nearly reached Tesla's level of genius."
Sol felt his mind clearing, vast knowledge flooding in for the first time. He couldn't help but savor it. If I'd had this brain before crossing worlds, I'd at least have become some big-time financial criminal.
With this new knowledge and power, he couldn't help but look down on his past self as a fool.
Now, while building a Gundam with bare hands might be a stretch, whipping up an exoskeleton armor was no problem.
With these abilities backing him, [Electromagnetic Control LV5] surged to new heights.
No, under Tesla's influence, it should now be LV5.5—just a step closer to the divine realm of halting Earth's rotation.
With a flicker of intent, faint violet sparks danced in his palm.
Compared to his earlier instinctive fumbling, his control was now precise—microscopic.
The same current could now drive a railgun with twice the firepower.
With finer control, he could extend the electromagnetic acceleration path, further magnifying its destructive potential.
Stacked together, his current railgun could fire a fifty-kilogram tungsten slug at twenty times the speed of sound, easily piercing through an entire street of Sixth Street.
If he could push Electromagnetic Control to LV6, the divine threshold, then halting Earth's rotation for even one second could erase civilization itself.
"Feels like you suddenly got stronger… am I imagining things?"
Baal frowned, scrutinizing the arc on Sol's fingertips.
Strange. It was clearly the same ability, yet he felt leagues stronger than her.
"As expected of the Former Electro Archon—you have keen senses." Sol patted Baal's head with a smile. "But no, not a little improvement. A massive one."
"My electromagnetic control's strength doubled, and my precision increased more than tenfold."
At this level, he felt truly omnipotent.
A thought began to stir—he might even attempt magnetic field rotation.
With LV5.5 strength, he could likely drive field rotation up to 200,000 horsepower—roughly the power of a humanoid nuke, perhaps even enough to tank a small nuclear explosion unscathed.
"You're not wrong, I can feel it," Baal muttered, confused. "But… you didn't do anything. How did you improve?"
She remembered last night—Sol had only gone to bed. No special training at all.
Such a drastic leap overnight was hard to accept.
"Maybe… that's just what it means to be a genius."
Sol sighed dramatically.
Baal rolled her eyes, exasperated.
Next, Sol turned to the remaining golden items.
[Sea of Trees Shuttle: Allows traversal between worlds of the Tree and Sea, based on an item's world of origin.]
[Leyline Stone], [Teyvat Fried Egg], [Revival Coin: Revives a dead person to perfect condition. (Can be used on others; auto-activates if host dies.)]
"Three revival items… guess my little life just got a lot safer." ɴᴇᴡ ɴᴏᴠᴇʟ ᴄʜᴀᴘᴛᴇʀs ᴀʀᴇ ᴘᴜʙʟɪsʜᴇᴅ ᴏɴ novel_fіre.net
Looking at the set of resurrection tools, Sol felt reassured.
Even with Yàn Shuāngyīng's Concept Techniques keeping death at bay, there was no guarantee. One day, a foe too strong might ambush him before he could react.
In that case, these three revival items would save him.
In this world, few could kill him outright. But other worlds weren't so forgiving.
The [Sea of Trees Shuttle] proved he could travel between them.
With world-bound items as anchors, he could cross into Teyvat, the starry realms of the Astral Express, even the collapsed domains of Honkai.
Archons, Thrones, Heavenly Principles, Herrschers, Honkai beasts, Emanators, Aeons—all beyond his current reach.
With only city-level strength, he wasn't even close. Compared to an Aeon of Erudition in the Astral Express, or even a minor Doomsday Beast, he was nothing.
Still… if possible, he wanted to see those worlds.
Thinking of Stellaron Hunters and that blond brat, Sol's fingers itched.
Not for their beauty—but to show them there was always someone more shameless.
Pray, Abyssal Prince of Misrolls… may the stars still shine upon you.
Calming himself, Sol's gaze shifted at last to the final self-selected golden card.
