Kochou Shinobu also covered her lips, her purple eyes filled with shock.
She finally understood why this father and daughter's bloodline could resist Muzan's erosion.
This inheritance was definitely not simple.
Inside the isolation room, after Himura Senichi intermittently spoke of his ancestor's dream and that fleeting glimpse of swordsmanship, the clarity in his eyes receded like a tide.
The sharp sword intent dissipated, and he let out a suppressed growl from his throat, his body once again struggling uncontrollably.
His crimson eyes were once again filled with chaos and pain, but the intensity of his struggle seemed to have weakened slightly compared to before.
"Dad!" Ruri's newly ignited joy was instantly replaced by worry, her fingers tightly clutching the armrest of the wheelchair.
"It seems that his lucidity is only temporary; his will is still in a tug-of-war with the demon blood."
Kochou Shinobu sighed softly, her tone complex.
Even as a doctor, facing demons, her inner aversion was still difficult to completely eliminate.
But Himura Senichi's special condition forced her to suppress these emotions.
Cheng Mo did not speak, the faint golden glow of the Eye of Truth silently flowed in his eyes, carefully examining the energy flow within Himura Senichi's body.
He keenly noticed that after this brief period of lucidity, the violent demon blood energy within Himura Senichi seemed to have been further suppressed, or even… partially assimilated, by some deeper power?
The erosion rate had significantly decreased, and the cellular activity that was originally tending towards complete demonization was slowing down, slowly evolving towards a peculiar state that was neither entirely human nor an ordinary demon.
"Was it that the special bloodline was thoroughly activated, combined with his own strong willpower, that guided this mutation?" Cheng Mo quickly analyzed in his mind.
It was almost like… a completely new evolutionary direction?
He immediately made a decision.
Cheng Mo turned to Kochou Shinobu, his tone serious: "I need to extract a sample of his current blood."
Kochou Shinobu was slightly startled, then nodded: "Okay, I'll prepare the equipment now."
She didn't ask further; Cheng Mo's actions always had a clear purpose, and she trusted his judgment.
Soon, through a special sampling port, a dark red blood sample, faintly shimmering with a barely perceptible golden luster, was taken by Cheng Mo.
He carefully stored it in a specially designed refrigerated container.
"The instruments in this world are still too rudimentary…"
Cheng Mo thought.
"I'll take it back to the lab and analyze it with more precise instruments; I should be able to discover more."
He carefully put away the sample, a plan already forming in his mind.
Over the next two days, the atmosphere at Butterfly Mansion lightened considerably due to Himura Senichi's brief awakening.
Especially for Himura Ruri, the hope of her father regaining consciousness was like a ray of light, dispelling the gloom that had accumulated in her heart.
Color began to return to her pale face, and her smiles became noticeably more frequent; she even ate half a bowl more than usual during meals.
"Miss Ruri, you look so well today!"
When Tanjirou brought lunch, seeing the natural smile on her lips, he couldn't help but say sincerely.
He could smell that inner joy, filled with hope, which also made him very happy.
"Mm!"
Himura Ruri nodded vigorously, her eyes curved in a smile.
"Thank you, big brother Tanjirou, I feel that Dad will definitely get better!"
Looking at her clear and bright smile, Tanjirou rubbed the back of his head and chuckled honestly: "Mm! He definitely will!"
Meanwhile, Cheng Mo's cultivation and demon-hunting journey did not stop.
After absorbing the rudimentary technique ideas about energy form changes from that "Blood Shield Demon," he had been making new attempts in the mountain forests far from Butterfly Mansion these past few nights… As night deepened, the mountain forest far from Butterfly Mansion once again became Cheng Mo's training ground.
Moonlight filtered through the sparse branches and leaves, illuminating the flickering azure electric arcs around him.
He closed his eyes and concentrated, repeatedly replaying the energy operation mode of the long-necked demon manipulating blood to change its form in his mind.
He tried to integrate that "shaping" and "maintaining" technique idea into his own violent Lightning Release Chakra.
This was by no means easy.
The essence of Lightning Release was violent destruction and rapid penetration, completely different from the fluid changes that could be commanded at will.
After countless attempts, the result was either the Lightning Release field collapsing and exploding, or it simply couldn't condense into shape.
But what he lacked least was patience and analytical ability.
"If I can't change its form as freely as it does… then I'll abandon complexity and pursue extreme simplicity and stability…"
Cheng Mo continuously deduced and adjusted the output frequency and form constraints of his Chakra in his mind.
The lightning arcs around him began to flicker, emitting a faint "sizzling" sound.
He slowly raised his hands, palms facing each other.
Clap!
Suddenly, he clapped his hands together sharply, producing a crisp sound.
Highly condensed Lightning Release Chakra fiercely compressed and converged between his palms.
Dazzling azure lightning flashed, illuminating his calm profile and the surrounding area.
The powerful energy fluctuations caused the air to tremble slightly.
Crackling —!
Amidst the harsh thunder, a throwing spear, entirely composed of highly condensed Lightning Release Chakra, was slowly "pulled" out between his palms!
The spear body was about 1.5 meters long, shimmering with dazzling azure light, and the violent energy was forcibly constrained into shape, emitting a heart-pounding hum.
Fine beads of sweat appeared on Cheng Mo's forehead; maintaining this form required extremely high demands on his mental power and Chakra control.
He slowly gripped the hilt of the lightning spear.
The touch was a burning numbness, as if he were holding a surging bolt of lightning.
He took a deep breath, his waist tightening with effort.
Cheng Mo's body was like a fully drawn strong bow, and he violently hurled the lightning spear!
Whoosh —
The lightning spear transformed into a blinding blue-white flash of lightning, instantly cutting through the darkness.
It accurately plunged into a huge rock nearly a hundred meters away.
There was no deafening sound, only a dull "thud."
The next moment, a point of extreme lightning surged out from within the giant rock, rapidly expanding!
Boom!!!
The massive rock exploded violently from its center, as if buried with high explosives!
Countless fragments of rock, enveloped in dust, scattered everywhere.
The largest pieces even flew more than ten meters away, breaking several small trees.
The power was astonishing!
In the treetops, the Black-Feathered Crow, who had witnessed the entire scene, watched with wide eyes.
Even though it had long seen Cheng Mo's various methods, it was still shocked by this violent and direct blow.
The speed and penetration of that lightning spear, as well as the destructive explosion from within… "This power… it's almost like divine punishment…"
The Black-Feathered Crow was horrified, and its awe of Cheng Mo deepened further.
