The Rule Book, no matter how fierce, was only a Semi Origin Artifact. It lacked the Primordial Source aura that could smother an Overdeity Level fighter, like a blade without its sheath’s chill. So, from the opening clash, Lingxiao and Lingsaki were thrown into a grinding storm.
They could accept being outmatched; shame burned but words failed, like smoke curling under a closed lid. What stung was this—Lixin and Rangetsu toyed with them like cats patting a mouse, striking at whim, forcing them to turtle up under a rain of blows, leaving almost no windows to strike back.
Beating the sisters down slow felt sweeter than ending it quick; both Lixin and Rangetsu savored that bitter taste like old wine, because their hatred for the Mizumi Clan ran like a scar across ice.
At this point, unless someone at the Origin Realm moved, Yumigawa Sumeragi’s group had no way to flip the board, like a boat trapped in a whirlpool. You could say the victor was settled before the bell even rang.
Every divine art they cast got swatted aside or only managed to offset an incoming spell, like sparks snuffed by a gust. The frustration piled in their chests like wet snow.
Even when they unfolded the Daynight Domain, the effect was meager, like a paper umbrella under monsoon rain. The gap was a canyon. Lingxiao and Lingsaki had reached the Divine Realm, and with the Rule Book they could burst into peak Divine strength, yet against two Overdeity Level foes, there was no path to win, only a slope of scree.
Rangetsu, at Overdeity peak, pushed them to despair like a mountain shadow at dusk. Unlike Lixin, whose power was partly shackled, Rangetsu could go all out whenever he felt like it, like a storm that chose its own hour.
Full force at Overdeity peak—just the thought was a thunderhead in the skull. Run? No. The road had already collapsed behind them. All they could do was fight on, like candles straining against a crosswind.
Facing two Overdeity Level enemies, every move had to be one of their strongest divine arts, like drawing blood with each breath. The cost was brutal; the Supreme Divine Spirit Medicine in their pouches dwindled at a speed you could see, like sand pouring through a glass.
“As expected of the Mizumi Clan. Supreme Divine Spirit Medicine means nothing to them, like fruit off a branch.” Rangetsu’s voice was sour as iron. Every few arts, the sisters popped another Supreme Divine Spirit Medicine, and his heart bled like a cut palm. Those weren’t even his resources, yet pain ran through him like cold.
We scrape for one good Divine Elixir and call it a season, and you swallow Supreme Divine Spirit Medicine like they’re cheap tonics—what waste, like casting pearls into mud!
“Now you know how painful it is to fight the Mizumi Clan, President Rangetsu, don’t you?” Lixin’s tone had gone numb, like frost calcifying a pond. The poor get numb watching the feasts of nobles; she was the same watching this waste.
“Yeah. It’s painful.” Rangetsu ground his teeth. His voice was a knife on bone. “We can’t let them keep wasting like this. Time to get a bit serious.”
Pressure surged. In an instant, the sisters went from bracing to dodging everywhere, like swallows harried by hawks. The indignity burned in their throats like smoke.
“Lingsaki, this won’t work. We’ll lose soon.” Panic rose first, then action. Lingxiao slipped past Lixin’s summoned beasts and Rangetsu’s blasting spells, breath ragged like a bellows. Gulping Supreme Divine Spirit Medicine only stretched the losing clock; it didn’t bend fate.
“No good options.” Resignation hit first, then words. “Emperor’s and Lixue’s situations won’t be better than ours. We got careless. We walked into Cerol City with no prep and straight into their net. Call it the slap our pride needed.” Lingsaki’s sigh came like a cracked reed. She’d never imagined falling this far.
“It’s true. We were careless.” Gloom pressed first, then thought. “I didn’t expect the Dark Demon, those outworlders, and the Besalot royal house to put their whole weight into crushing us.” Lingxiao’s mood was leaden, like clouds before hail. She knew a shadow of what Emperor and Lixue faced; that made the cliff feel higher.
“How about we try an Overdeity Level magic from the Dual Daynight Tomes?” Lingsaki’s voice was a quiet knife.
“But…” Doubt came first, then caution. “With our current strength, that’s too much. If we fail, the backlash isn’t a joke.” Lingxiao’s heart lurched like a bird at glass.
“Do we have a choice?” Lingsaki cut in crisp as ice. “Not even peak Divine arts can threaten an Overdeity Level. Only Overdeity Level magic can meet them head-on.” She knew it like a mountain knows snow. If Lixin and Rangetsu got bored and threw down an Overdeity Level spell, they’d be swept aside like reeds.
“You’re right. No options left. We go all in.” Lingxiao bit down, resolve setting like iron. They dodged at full tilt while flipping the Dual Daynight Tomes to the Overdeity pages, like gamblers finding their last card in a storm.
As long as the Supreme Divine Spirit Medicine didn’t run dry, they still had a ember to stoke, like coals under ash.
They chose a joint magic—one only two could cast—Stillness: Day Sky Night Demon. It was the paired Overdeity Level magic for the Daynight Domain. If they pulled it off, its bite would rival Overdeity peak, like a comet carving the night.
Two conditions made the head ache like a nail. First, the cost was monstrous. To cast Stillness: Day Sky Night Demon above their tier, they needed to pour in more than ten times their own mana and power of Laws, like feeding a furnace with a forest.
The power of Laws was fine. The Book of Day and the Book of Night were in their hands, like twin moons over dark water. The mana demand meant swallowing ten Magic Spirit Fruits in the casting. Those were Supreme Divine Spirit Medicine that instantly restored all mana and spirit, their surge lasting half a month, once per day, like a tide that refills at dawn.
That first condition, they could bite through. The killer was the second: they had to commit wholly to casting and could not be disturbed, like a monk in meditation under falling snow.
In this mess, “undisturbed” was a joke. Even dodging Lixin and Rangetsu had them spent and shaking, like deer on ice.
Unless something blocked those attacks for a while. Defensive magic? Barely worth a prayer. If it worked, they wouldn’t be burning divine arts just to cancel incoming spells.
Even peak Divine defense shattered at a touch before Lixin and Rangetsu, like thin glass under a hammer. It couldn’t buy them a single heartbeat.
“Lingsaki, no choice. Let’s see what the Daynight Domain can do.” Determination cooled first, then order.
“Yeah. That’s all we’ve got.” She cast aside impractical wishes like chaff and gripped the blade that was left. They stacked every defensive buff they had onto the Daynight Domain.
“Daynight Domain, full defense mode!” The command rang like a bell.
It was barely holding. Under Lixin and Rangetsu’s bombardment, the Daynight Domain shuddered like a lantern in gale. It could last a little longer—if those two didn’t suddenly get serious.
They reinforced the Domain again and again, then launched the prep for Stillness: Day Sky Night Demon. At once, torrents of power of Laws and the twin elements of light and dark gathered to them, like rivers bending to a whirlpool. The sky rippled with omens. Gigantic magic circles bloomed one after another, surrounding the area and knitting into a barrier like frost lacing a window.
A bad feeling pricked both Lixin and Rangetsu like thorn-bushes. They pumped their output. Cracks forked across the Daynight Domain, and every groan said it might shatter at any breath.
Lixin hurled attack magic without pause and sicced her summoned beasts to harry the sisters like wolves at a sled. But a shield of congealed power of Laws wrapped Lingxiao and Lingsaki, and even her peak Divine summons couldn’t break through fast.
They wanted to answer with Overdeity Level magic themselves. Even at their level, they needed casting time, like a bow that must be drawn. Now, there wasn’t enough. So they kept up the peak Divine bombardment, pounding the Daynight Domain until it looked like cracked porcelain.
“Still not ready?!” Anxiety hit first, then grit. Fissures multiplied across the Domain. Its presence flickered, unstable as a candle flame. The Stillness casting was only halfway, and the latter half demanded even sharper focus. At this rate, the Domain might not last that long.
The casting itself was agony. Over and over, their stamina and mana were drained in an instant, then they swallowed a Magic Spirit Fruit to refill, then drained again, like waves scouring a shore. The Dual Daynight Tomes pressed down their pain like snow muffling sound; without that, they’d have collapsed.
They pinned all hope on this one Overdeity Level magic, like archers staking everything on a final arrow. Success or ruin—nothing between.
“Lingxiao, we can’t keep strolling through prep. Double the output of mana and power of Laws!” Pain crashed first, then resolve. Lingsaki’s words were a hoarse thread.
“But our bodies—” Fear twitched first, then steel. Lingsaki cut her off. “No time. We won’t sit here and wait to die. We have to break out with Emperor, Lixue, and Lanxia.”
“You’re right.” Doubt burned off like morning mist. To shorten the casting time, they paid a heavier price, like feeding blood to a seal.
At the brink of the Domain’s collapse, Stillness: Day Sky Night Demon finally reached casting completion. They hadn’t failed. Each magic circle shed twin beams of Law-light, one black, one white, like twin dragons painting the night, and they lit the Cerol City sky.
The power flooding off the circles was terrifying, like a tide that tore docks free. Lixin and Rangetsu felt their guts chill and both cursed, bad timing heavy as lead.
Pale-faced, without even a breath to spare, the sisters released their first Overdeity Level magic—
“Stillness: Day Sky Night Demon!”
Power of Laws in light and dark surged from the circles and erupted, like day and night colliding. Lixin and Rangetsu were forced to throw everything into defense, like knights bracing shields under a falling cliff.
Then, clear as a silver bell, a loli voice rang in the sisters’ minds. Surprise bloomed first, then attention. “Hurry and follow me to Boss Yumigawa Sumeragi. I’ve got a way to get you out of here!”
