[Lightning Arc!] Lin Ye unleashed the lightning-based beginner spell he’d practiced no less than five thousand times. A purple current shot toward Ling Ling.

[Haha! As expected of my little brother! Your casting speed’s gotten even faster! You’ve made it to third place on my personal speed ranking list. But—] [Ice Wall!] A thick wall erupted from the ground, blocking the purple current.

Almost simultaneously, Lin Ye cast the beginner fire spell [Fire Blast], shattering Ling Ling’s ice wall. But he suddenly realized she wasn’t behind it.

Ling Ling appeared behind Lin Ye, shouting the mid-tier ice spell [Ice Spikes!] Sharp ice spikes flew at him. Yet the moment they hit, Lin Ye turned into wood!

Ling Ling’s eyes widened in shock. There, behind her, Lin Ye materialized, raising a knife to strike.

Ling Ling sighed and activated the advanced spell [Ice Domain]. Instantly, the area within ten miles froze solid—even birds and animals turned to ice. Lin Ye’s body stiffened from the cold. Ice spikes formed in Ling Ling’s hands, stopping just twenty centimeters from him!

[I lose. Sister’s still the strongest!] I praised.

[Don’t flatter me! At first, you couldn’t even force mid-tier spells from me. Now you’ve pushed me to advanced magic. But—who taught you those ninja techniques?] Sister asked curiously.

[Uh, a friend. They’ve returned to Japan now,] I sighed.

[Boy or girl?] Sister demanded, stressing "girl."

[Girl—uh, no, boy!] I answered, sweating.

[So it’s a girl.] A dark, deathly aura radiated from Ling Ling, making Lin Ye sweat buckets nearby.

[Boy! It’s a boy!] I blurted out.

[Oh, good. But Yeer, don’t reveal your ninja techniques in team battles. We’ll catch Li Honggang off guard,] Sister said cheerfully, her mood brightening.

[Mhm! Understood, Sister,] I replied calmly.

[Little brother, to repay me for training you, shouldn’t you show some gratitude?] Sister leaned close, smiling.

[Ah! What kind?] A deep unease filled my heart.

[Bathe with me,] Sister purred seductively.

[Ahhh!] I yelled in panic. [We’re adults! We can’t bathe together!]

[What did you say? Repeat it!] Ling Ling growled, face flushed with rage. Seeing her like this, I knew escape was impossible tonight. Better start planning how to keep my dignity intact.

After dinner, I cleverly said, [My stomach hurts. I can’t bathe today. Sister, you go first!]

Sister just stared. Tears welled in her eyes as she whispered tearfully, [Yeer, do you hate Sister?]

[Fine! I’ll go!] Since childhood, I’d feared Sister’s tears more than elementary school spankings—she’d cling and even bite!

[Um, I’m coming in!] Sister pushed the bathroom door open, voice shy.

[Sister, don’t face me!] I stood with my back turned, terrified of seeing her.

[Yeer, turn around. Be honest with me!] Maybe I misheard, but she spoke like she was eyeing a feast.

[No, I can’t,] I stammered, face burning red.

[So cute! Yeer, I want to devour you now!] Sister lunged, pressing her ample bosom against him and rubbing. She breathed hotly into his ear.

Ah! The sensation overwhelmed Lin Ye. His little friend stirred wildly. To keep his sanity, he broke free from Ling Ling and bolted out.

[Sorry!] Lin Ye shouted.
