Feng Yu sat on the bed, staring at Shinobu Kocho, who always wore a sweet smile on her face, and couldn't help but remember the prequel anime about her, Kanae, and Kanae’s sister that he had watched in his past life.

  This girl used her smile to cover the pain inside her heart.

  She wasn’t suited to be a Demon Syer because her wrist strength was insuffit—she was the only one in the Demon Syer Corps who couldn’t decapitate a demon. But in order to avenge her sister, she found a different path, using her expertise in pharmacology and toxicology to develop poisons that could kill demons, pensating for her physical limitations.

  She eveed her owhing teique—Breath of the I—making her both a genius and a tragic figure.

  In the past, Shinobu Kocho was serious, stern, and straightforward, with a petitive and short-tempered side. After her sister, Kanae, passed away, Shinobu underwent a profound ge. She began to imitate her sister’s as, speech, and personality, maintaining a posed demeanor, and started to smile at all times, just like Kanae.

  When Shinobu Kocho was angry or serious, her face would bee expressionless. In moments e, she would remind herself, “Being uo trol your emotions is a sign of immaturity.” She would try to trol her facial expression and calm down as much as possible.

  At this moment, Feng Yu uood that Shinobu Kocho was attempting to i poison into herself, hoping to die alongside Upper Rank Two, Doma, as a form of mutual destru.

  Feng Yu admired her ce but also thought she was foolish. Life holds hope, and even if that hope seems faint, one should learn to proteeself first.

  He uood why she had asked him to demonstrate two breathing teiques earlier—she wao bee stroo increase her ces of defeating Doma iure.

  "No matter what, if we reduce the tragedy even a little, it’s better than nothing…” Feng Yu sighed as he walked toward the training square.

  In the ter of the square, Shinobu Kocho was already waiting for him.

  “Feng Yu-kun, you’re here…” Shinobu Kocho said, smiling.

  “Shinobu…” Feng Yu responded.

  “Feng Yu-kun, is there something you want to tell me?” Shinobu Kocho asked, her expression suddenly turning cold when she saw the hesitation on his face.

  “No…” Feng Yu quickly denied, feeling a chill run down his spine when he saw her smile again.

  “Then, Feng Yu-kun, tell me how you mao master two breathing teiques,” she asked.

  “Actually… I don’t really know why I master two breathing teiques. It just came to me suddenly…” Feng Yu couldn’t expin it clearly. Ultimately, it was because his body’s recovery ability was s that he wasn’t afraid of the irreversible damage caused by switg betweehing teiques.

  “Maybe it’s because of my physical stitution…” Feng Yu added.

  “I see…” Shinobu Kocho observed Feng Yu thoughtfully.

  “Feng Yu-kun, could you demonstrate your self-created breathing teique for me?” Shinobu Kocho requested.

  “Sure!”

  Feng Yu then began to demonstrate the two teiques of the Breath of Light for Shinobu Kocho.

  "Total tration, First Form of the Breath of Light: Moonlight Ssh…”

  “Sed Form of the Breath of Light: Radiance Shining Across the World.”

  “These are the two teiques I’ve developed so far…”

  Feng Yu fihe demonstration.

  “Incredible, Feng Yu-kun! Your sed teique actually made me feel the warmth of the sun…” Shinobu Kocho’s face showed astonishment. “And this intense light might even surprise demons during battle!”

  “Feng Yu-kun, you demonstrate the transition from your Water Breathing to Light Breathing?” she asked eagerly.

  “Mm, I .”

  Feng Yu first used the Water Breathing teique, then switched to the Light Breathing teique.

  The two teiques seamlessly transitioned.

  Shinobu Kocho watched attentively, her smile gradually fading as her gaze remained fixed on Feng Yu’s face.

  “Hah~” Feng Yu exhaled after finishing the demonstration.

  “Very impressive, Feng Yu-kun. None of us in the Demon Syer Corps have been able to switch betweehing teiques without injury like you have,” Shinobu Kocho praised.

  “Feng Yu-kun, how does your body feel when you switch from Light Breathing?” she asked.

  “How does it feel? Well… it feels a bit unfortable, and there’s some damage to my body…” Feng Yu answered holy.

  Shinobu Koodded in uanding. The Demon Syer Corps had previously tested whether one person could learn and use more than one breathing teique, but it usually ended in failure. The greatest challenge was the disfort.

  Even the Hashira could learn two breathing teiques, but it didn’t increase their power; in fact, it caused harm to their bodies. The Demon Syer Corps focused on increasing strength, not weakening it.

  Shinobu Kocho walked around Feng Yu, then suddenly drew a knife and lightly cut his skin.

  “As expected…” Shinobu Kocho observed the cut as it quickly scabbed over and healed.

  “Feng Yu-kun, it seems your body is quite unique…”

  She couldn’t resist toug the scab. As soon as she touched it, the scab fell off, revealing fresh skin without any trace of a wound.

  “Feng Yu-kun, are you of rare blood?” Shinobu Kocho asked abruptly.

  “Rare blood… I don’t know…” Feng Yu pretended not to know whether he had rare blood, though his body was far more exceptional—he had an immortality-type stitution, which had aronger recovery ability than rare blood.

  Moreover, before he acquired the immortality-type stitution, his recovery rate was already extraordinary, not to mention the various body-strengthening teiques he had.

  If Shinobu Kocho hadn’t let her guard down and sshed lightly, that wound wouldn’t have been possible. With just that little strength, even a membrane wouldn’t have been pierced.

  Shinobu Kocho’s eyes showed a hint of disappoi, but she still smiled.

  “How about… you take a look at this?” Feng Yu, feeling guilty, took out a detoxifying pill from his system spad pced it in Shinobu Kocho’s hand.

  “Feng Yu-kun… What’s this?” Shinobu Kocho looked at the small pill with fusion.

  “If you take it, you’ll know the effect… Just know that my body’s strength is partly due to it…” Feng Yu didn’t want to expin further.

  With some doubt, Shinobu Kocho put the pill in her mouth.

  “Numb… How this woman still be so beautiful whes something?” Feng Yu turned his head away, not wanting to look at Shinobu Kocho.

  “How is it possible!” Shinobu Kocho cried out in astonishment.

  Her face immediately brightened with excitement, feelirength growing.

  “Feng Yu-kun!” she excimed. “Where did you get this pill? you give me more? Or do you have the recipe for it?”

  “This pill is called Detoxifying Pill… Where I got it is a secret. I don’t have ma, but I give you one more for research…” Feng Yu said.

  “I see… That’s a shame, but it’s still very good…” Shinobu Kocho put the pill away, then noticed that Feng Yu had taken out two more Detoxifying Pills and hahem to her.

  “You take one more, ahe other for research. I hope you figure out its ingredients and mass-produce it,” Feng Yu said without batting an eyesh.

  “Feng Yu-kun, is this of the same quality as the healing pill Mr. Urokodaki gave me a year ago?”

  “You mean the Healing Pill?” Feng Yu finally remembered that he had given Urokodaki a Healing Pill, but didn’t realize he had passed it to Shinobu Kocho.

  “It really came from you, Feng Yu-kun…” Shinobu Kocho said, smiling. “I must thank you deeply because of your Healing Pills, our Demon Syer Corps has been able to reduce casualties.”

  “You mean the Healing Pill was successful?” Feng Yu asked, incredulously.

  “Yes and no, Feng Yu-kun. We only make a much weaker version of the pill. The main issue is that some of the ingredients seem to in this world…” Shinobu Kocho said, looking at Feng Yu with a strange gaze.

  “Feng Yu-kun, you’re such a strange person…” she added. “You give off the feeling that you’re someone who will sacrifice everything…”

  Then, Shinobu Kocho took the Detoxifying Pills a. She wao quickly research them and begin mass produ.

  After all, this pill was extraordinary. Her previously stagnant strength had noticeably increased, and the most surprising part was that her body had bee so much er.

  “I wonder… If I mass-produce it, will I be able to decapitate demons…” she thought as she left.

  Feng Yu stood still, watg her leave...

  "My secret ot be told. I'm sorry..."
