From the Start, I Raised a Prodigy Junior Sister, and Grew Stronger While Taking It Easy

Chen Ping transmigrates into a fantasy world, but his aptitude is so poor that he can only serve as the sect's mascot and senior disciple.

He's happy to take it easy, spending his days slacking off,

until one day, his System awakens. As long as he invests in a prodigy, he'll receive a ten-thousandfold return!

He invests in his junior sister, a reborn Empress, and gains supreme mastery of the sword. From the start, he's invincible in the way of the sword!

He invests in his second junior sister, born with a useless body, and gains an innate Dao Fetus. Combined with the Desolate Ancient Sacred Body, it makes his physical form invincible, and the Great Dao comes to him!

But Chen Ping doesn't know that the prodigies he invests in are all bound to a comparison System. If they challenge him and win, they can receive an Emperor's Weapon as a reward. Yet these girls, who should have been prodigies, lose to the utterly ordinary Chen Ping time and again.

All they can do is pout with tears in their eyes. "Senior Brother, please stop working so hard!"
