My Master and Senior Sister Both Have Systems, So I Have No Choice But to Lie Flat

[Invincible and satisfying novel + ruthless and decisive + system + multiple female leads + crushing weaklings]

Jiang Xin was surprised to discover that all the masters and senior sisters in his sect possessed a system!

The master has a disciple-recruiting system; recruiting disciples will make him stronger.

The eldest sister has a sign-in system; you get a prize for signing in.

The second senior sister awakens the killing system and uses it to help others attain enlightenment.

The fourth junior sister is a villainous empress reborn, accompanied by a major villain system.

Jiang Xin had no choice but to bind them to his "soft rice" partners and start a "laissez-faire" mode.

[Master receives a reward for accepting a disciple: a 100,000-year-old Vermilion Fruit; you receive a reward for returning the favor: a million-year-old Immortal Dew Fruit!]

[The eldest sister received a sign-in reward: Nine-Turn Yuan Pill; you received a "soft rice return" reward: Nine Tribulations Heaven-Mending Pill!]

[Your junior sister steals a destiny-bound opportunity, boosting her cultivation by a thousand years; you, in return, receive a ten-thousand-year increase in cultivation!]

...

Years later, Jiang Xin stood atop the myriad realms and said calmly, "My ability to become the Heavenly Emperor is entirely due to the efforts of my sect!"
