Since the Pillar Meeting, Hiro has been able to stay on as Kagaya Ubuyashiki's teacher and the temporary instructor of the entire Demon Slayer Corps.
The technique he taught Ubuyashiki Kagaya was quite unique, even among the many byproduct techniques he deduced.
Ji Hao even gave a name to this special byproduct of his cultivation technique: "The Merit and Virtue of All Beings".
Just as its name suggests, the core of this cultivation method lies in the merits borne by the cultivator.
The higher the merit a cultivator possesses, the faster the cultivation speed brought about by this technique will be.
Conversely, those with little merit who attempt to practice this method will suffer a backlash from their own merit and fortune.
At best, it will bring bad luck; at worst, it will cost you your life!
As for the Ubuyashiki clan, the burden of a thousand-year-old wish, coupled with their thousand-year-long achievements in slaying demons, was enough to allow Ubuyashiki Kagaya, who was cultivating this technique, to achieve an astonishing speed in his cultivation.
After all, from the perspective of plot development, the Demon King Muzan will inevitably be completely ended in his generation.
In a sense, this also indirectly confirms that the Demon Slayer Corps' efforts over a thousand years have allowed the Ubuyashiki clan to accumulate enough merit.
It's time to resolve our destiny.
"Calm your mind and spirit, and let your energy flow throughout your body. The merit accumulated over thousands of years is on you. Always remember, you are not just doing this for yourself."
He glanced at Kagaya Ubuyashiki, who was sitting cross-legged in the courtyard, his body trembling.
Ji Hao simply picked up the teacup and took a sip of tea.
Kagaya Ubuyashiki's internal condition is complicated.
Because Kibutsugu Muzan was the ancestor of the Ubuyashiki clan.
This ancestor transformed into a ghost king, causing his own bloodline to be cursed with insidious poison.
Under the influence of this insidious influence, none of his descendants were able to live past the age of thirty.
This is the result of generations of Ubuyashiki family heads marrying daughters from a Shinto family under the Ubuyashiki clan, and through continuous improvement of the bloodline.
Otherwise, it would be quite difficult for members of the Ubuyashiki family to live past twenty-one or twenty-two.
Kagaya Ubuyashiki is currently battling the insidious poison within his body, and he can only rely on himself for this step; no one can help him.
At this moment, under the sunlight, Kagaya Ubuyashiki's body was constantly emitting wisps of white smoke.
That was the manifestation of the evil poison in his body being forced out by the power of merit. Once it was all forced out, he would be no different from a normal person.
"Sit still. He can't move anyone right now, or all our efforts will be wasted."
Suddenly, Ji Hao put down his teacup, and used his folding fan to block the woman who was trying to get up, his tone becoming serious.
"Lord Ji Hao, my husband..."
A hint of reluctance flashed across Ubuyashiki Amane's pale face; after all, it was her husband who was suffering.
"Failure will hasten his death; if you wish, then go."
Ji Hao casually put away his folding fan, his tone indifferent.
"..."
Upon hearing this, even though she was in a hurry, Ubuyashiki Amane dared not move around.
"Uh... Ah...!"
Just then, Kagaya Ubuyashiki suddenly trembled violently, and then, in front of Amane Ubuyashiki's horrified gaze, he spat out a mouthful of pitch-black blood.
Blood sprayed like ink onto the ground in front of him, and the instant it hit the ground, it acted like a highly corrosive liquid, sizzling and corroding a large patch of grass!
Even the ground itself has turned completely black!
"It's done!"
Before the panicked Ubuyashiki Amane could even ask a question, Himeko suddenly slapped his folding fan and appeared beside Ubuyashiki Kagaya in a flash.
Then, with a palm strike, he slapped directly onto his back!
"Bang!"
Amidst the powerful surge of spiritual energy, Kagaya Ubuyashiki's body jolted violently.
He could feel as if his body had been baptized; his body, which had been somewhat uncomfortable, now felt incredibly clear and refreshed!
"What am I doing...?"
Kagaya Ubuyashiki slightly opened his eyes, the bright sunlight making him squint.
But he soon noticed something was amiss...
He quickly covered his right eye and widened his left eye.
But then he discovered that his left eye, which had been blind for a long time, could now see the sunlight.
He touched his cheek again; the skin, which had been disfigured by the curse, had now smoothed out...
His illness is cured...
"Lord Ji Hao..."
In his emotional state, Kagaya Ubuyashiki wanted to prostrate himself in gratitude as before, but Himeko casually helped him up, preventing him from kneeling even slightly.
"Just got back to you. Take good care of yourself. Come to Butterfly House every day, and I'll prepare some medicine for you to recuperate. It should take about a week for your body to recover."
Ji Hao smiled and continued calmly.
"Let's get this straight: I'm not exactly a nice guy when it comes to training people. Don't blame me if you end up crying from the training."
"Yaozai will absolutely not blame Lord Himehiro!"
Kagaya Ubuyashiki also spoke up anxiously.
"Alright, rest now. You two can have some fun here. I should head back now, hahaha."
Ji Hao spoke jokingly, then turned and left under the grateful gazes of the Ubuyashiki couple.
"Hmm, as expected of the cultivation technique I deduced, it is indeed very useful."
Ji Hao stroked his chin and spoke in a rather narcissistic manner.
He was very confident in the cultivation technique he had deduced, and he even had a 'guinea pig' to use for experiments.
As it turned out, his deduced "The Secret of Merit for All Beings" was a great success.
The downsides...
This technique has too many restrictions; only those with accumulated merit can cultivate it, otherwise they are likely to die suddenly...
"Hello!"
"What should we eat later? I'll ask Kanae to make something delicious~"
"Hey! I'm talking to you!"
"I'm thinking of buying something. How about I invite Kanae down the mountain to go shopping...?"
"You bastard! Don't ignore me!"
"Wow, there are so many flies in the mountains! How annoying!"
Ji Hao waved his hand dismissively, as if he were shooing away some annoying white-headed fly nearby.
"Who are you calling a fly!"
Shinazugawa Sanemi grinned, staring fiercely at Ji Hao, as if he wanted to tear Ji Hao's mouth apart.
"That buzzing is really annoying."
Ji Hao simply waved his hand, ignoring Shinazugawa Sanemi's anger.
Sanemi Shinazugawa shouts "Hey!", but Himeko doesn't say "Hey!" So who is he calling here?
"Oh dear, I should go back and have a heart-to-heart talk with Ms. Kanae... Hehehe..."
"You bastard! Ji Hao! I challenge you to a duel!!!"
Seeing that this man kept mentioning Kanae Kocho, Sanemi Shinazugawa became unusually angry.
In his anger, he roared out the word "duel," which made Ji Hao pause slightly.
"Okay, but are you sure, Wind Pillar, Shinazugawa Sanemi?"
Ji Hao slowly turned his head, looked at Shinazugawa Sanemi, and revealed a very healthy smile.
duel?
Ever since he became invincible in his original world, even his teacher, who lived in seclusion in the deep mountains, was defeated by him in the final battle.
He hadn't heard that word in a long time.
"Aren't you scared?!"
Shinazugawa Sanemi gritted his teeth and continued his provocation.
"Me? I'm afraid I'll beat you so badly that you'll never dare to carry a knife again."
