Zongman: Many Children Bring Happiness, Starting with Asuna!

When Lin Ye woke up, he found that he had traveled through time and was bound to a [Many Children and Many Blessings System] - as long as he married the heroines of anime and had children, he would become stronger!

System: "Host, you have entered Sword Art Online. Please capture Asuna. Reward: Dual Blade Style - Modified!"

Lin Ye: "Wait, doesn't she have an official partner?"

System: "Open the pattern! Kirito? That's your future brother-in-law!"

then--

In "Date A Live", he successfully made Origami shout "Onii-chan" instead of "Go to hell, scumbag".

In Honkai Impact 3rd, Mei Raiden holds a knife to his neck and asks, "Say 'many children, many blessings' again?"

Lin Ye (calm): "Wife, listen to my explanation... This is really about saving the world!"

While other travelers were still struggling to fight monsters and level up, Lin Ye had already swept across the heavens with a group of cute kids.

"Dad! Uncle Gojo Satoru is teaching me the Unlimited Technique!"

"Mommy! Aunt Bulma said to build me a mecha!"

"Host, a new mission has been detected: Demon Slayer: Kocho Shinobu's favorability towards you increased by 50%..."

Lin Ye (holding his waist and sighing): "Tongzi, your mission...is it serious?"
