Son-in-Law: I Slay Gods and Demons with Daily Check-Ins

[Urban high martial arts + live-in son-in-law + one heroine + transmigration + System + lie flat]

Mu Chen transmigrates to a modern parallel world where martial prowess reigns supreme. Not only is he a good-for-nothing with mediocre martial arts talent, he's also a live-in son-in-law tied to a wealthy family by a “contract.” Luckily, he gets the transmigrator's perk, the Clock-In System: clock in on time each day to earn free attribute points, and get stronger by assigning them.

“Ding, Clock-in successful. You received 5 free attribute points.”

The System panel displays:

[Name: Mu Chen | Realm: Mid-stage Martial God (hidden: Mid-stage Martial Master) | Consecutive clock-ins: 1,826 days].

“Mu Chen, the family is gathering today. Stay in the library and don't come embarrass us.”

Mu Chen nods. “Okay, Mom.”

Ye Qingcheng frowns but says nothing.

Five years ago, she signed a three-year marriage contract with this “martial arts failure” to avoid marrying the Lin family's genius. Now, in its fifth year, the contract has been renewed again.

Mu Chen starts “training in public,” practicing a set of health-preserving exercises in the library's back courtyard every day.

The students laugh when they see him. “Even my grandma knows that routine.”

Mu Chen finishes the set seriously. Inwardly, he thinks, “Hm, my acting was pretty good today, too.”

“Was it you?” Ye Qingcheng suddenly asks.

Mu Chen plays dumb. “What?”

Ye Qingcheng stares at him for a long while. “Nothing.” She's not sure, but the seed of suspicion has been planted.

“I won't marry! I want to become the Sword Emperor and protect the Ye family!”

His sister-in-law, Ye Qingxue, makes the announcement in front of everyone.

Lin Aotian sneers. “You? You think you can?”

In a corner, Mu Chen quietly infuses Ye Qingxue's sword tassel with a trace of sword intent.

Ye Qingcheng starts secretly observing Mu Chen: He always “coincidentally” appears at crucial moments;

The tea he brews calms the mind and aids cultivation;

The ancient texts he organizes are exactly the ones she needs... It's all too coincidental.
