Longevity through Upgrading Buildings Chapter 812 - 337: Mid-stage Muscle Forging Realm

"Regardless, congratulations first, fortunate one. To obtain the Miracle Treasure Chasing Lightning is indeed your fortune. Of course, the speed of this Chasing Lightning is rather ordinary, only barely sufficient for the Core Formation Stage and the early and middle stages of Nascent Soul, so it can't be considered a Supreme Treasure."

"However, in a way, it can indeed be considered a Supreme Treasure, because the even faster and more formidable Stepping Star Wheel... requires this Chasing Lightning Cloud to be obtained."

"It is regrettable that my strength was insufficient back then, preventing me from seizing that treasure; otherwise, I would not have perished in that calamity."

"Fortunate young one, if you are able to obtain this Chasing Lightning, it signifies you also have an affinity with the Stepping Star Wheel. If you manage to reach that Butcher Mountain in the future... hehe, best of luck, do not end up as a stepping stone for others like I did."

The aged and feeble voice let out a long sigh.

"Thousands of years of glory ultimately turn to dust, the mortal world holds no allure, life is but a fleeting dream, life is but a dream."

"Oh, and right, if you encounter any Merfolk outside when you arrive, show them some kindness; they are remnants of an old acquaintance of mine. Go on now, be on your way."

At this point, the voice began to fade. Ji Yuan could naturally discern that this voice originated from the formation inscribed on the stone wall.

This was because, just as he was completely refining the Chasing Lightning, the very same formation materialized once more on the stone wall where he had entered.

"I can't help but wonder who that esteemed senior truly was; this array technique is truly exquisite."

With an internal sigh, Ji Yuan finally focused his attention on the wisp of energy residing in his hand.

Compared to before, he could now perceive a distinct connection between himself and this ethereal wisp of energy.

"Chasing Lightning Cloud, a Miracle Treasure, reputed to pursue the thunder and lightning of the heavens... It typically manifests as an energy surrounding one's body and cannot be stored internally or within a storage bag. Once activated, it transforms into a cloud that chases lightning, traversing vast distances, and can also be unleashed as lightning to assault others."

These are the general applications of the Chasing Lightning Cloud.

Observing the wisps of energy slowly revolving around him, Ji Yuan could readily sense its depleted state, having expended considerable energy in its prior attempt to vanquish him.

One method to facilitate its recovery is through gradual nurturing with Spiritual Qi.

Another, more rapid approach exists.

Lightning Charging!

Despite his current location within an underwater cavern, Ji Yuan still possessed a means to summon lightning.

With a subtle mental shift, a sliver of sword light emanated from his Dantian, coalescing into a small, purplish sword that hovered at his fingertip, tiny sparks of lightning crackling around it.

Nine Waves of Canglan — Thunder Strike Sword!

With another thought, Ji Yuan commanded it to return to its normal size, a three-foot blue blade materializing. The tip of the blade was then pressed against the Chasing Lightning.

"Chzzzzz—"

Following this sound, arcs of lightning appeared, striking the Miracle Treasure Chasing Lightning. However, the lightning dissipated instantaneously, completely absorbed by this Miracle Treasure.

This process persisted for merely three to five breaths before the luminescence of the Thunder Strike Sword began to dim slightly. Ji Yuan hastily retracted it back into his Dantian.

After all, it was merely a sword embryo, not a fully realized Magical Treasure.

The lightning contained within was not substantial.

As for the refinement of a Magical Treasure subsequent to forming the Core, Ji Yuan had long harbored a specific intention.

Even though he was already in possession of his Lifebound Magical Treasure, the Mountain of Mind and Heart, his plan was to refine these nine sword embryos into another personal "Lifebound Magical Treasure."

The Purple Sky Stone, possessing the ability to generate Purple Sky Divine Thunder... Amongst Ji Yuan's current possessions, two such stones resided in his storage bag, with one designated for the Celestial Craft Square's upgrade.

Furthermore, upon elevating the Celestial Craft Square to Level 3, its output would increase to one Purple Sky Stone per month.

Over the span of a year, that would amount to twelve stones, enabling me to amass a considerable quantity by then.

This accumulation is vital until all nine sword embryos are infused with Purple Sky Stone. Though these nine sword embryos do not represent the ultimate limit of the Canglan Sword.

Nine giving rise to nine swords, ultimately capable of refining a total of eighty-one Canglan Swords, thereby forming the formidable Canglan Sword Array.

Yet, the prospect of simultaneously activating all eighty-one flying swords refined from Purple Sky Stone... Ji Yuan surmised that even his reach into the Nascent Soul stage might not grant him the capacity for such a feat.

Turning back to the present moment, after successfully absorbing the lightning essence from the Thunder Strike Sword, the Miracle Treasure Chasing Lightning finally reawakened, stirring with a faint glimmer of vitality and commencing an unceasing orbit around Ji Yuan.

As Ji Yuan's sword-fingers illuminated with a surge of Spiritual Light, the Chasing Lightning instantly morphed, taking on the appearance of a colossal dark cloud.

With a gentle leap, Ji Yuan ascended onto the dark cloud. His body became immediately ensconced within the light shield manifested from the Chasing Lightning, granting him the sensation of the Chasing Thunder Cloud materializing beneath his feet.

If charging with lightning proved unfeasible, then the alternative would be the expenditure of Mana.

Recalling the senior's earlier words, this Chasing Lightning Cloud possesses the capability for use up to the Nascent Soul Stage. Consequently, Ji Yuan had made preparations for a potentially significant Mana consumption.

However... the sheer magnitude of this anticipated consumption had not been fully grasped!
