I Made the Immortal Emperor System My Slave and Pulled a Ton of Brain-Dead Clansmen

[Unrestricted System + Brain-Off Power Fantasy + Decisive and Ruthless + No Female Lead] Ye Tian transmigrates to the Primordial World, where the original owner has already been buried. The System demands that Ye Tian sign a master-servant contract and become its master, but Ye Tian turns the tables and forces it to become his servant instead. Ye Tian cultivates in his grave, breaks through to the Nascent Soul Realm, and is dug up by grave robbers. Ye Tian returns to the Ye residence. Ye Tian: I came back to reclaim everything that belongs to me! Ye family disciple: They took your Heavenly Spirit Root, removed your Nine Apertures Exquisite Bone, and stripped away your Qilin bloodline. Even if you're alive, you're still a good-for-nothing. Patriarch Ye Zhentian: Look at your younger brother Ye Mao, so well-behaved. You come home and immediately make me angry! Ye Tian: You forced me to give up my Heavenly Spirit Root! You're all ungrateful old beasts! System Slave, am I going a bit too far with all this? Those old geezers are all in the Nascent Soul Realm. [Master, this old servant is a System who once served an Immortal Emperor. You have a Supreme Bone. Your Nascent Soul Realm power is enough to kill these Nascent Soul trash in an instant.] [The Great Desolate Prison-Sky Finger is a divine ability that lets you kill enemies above your cultivation level!] Eldest sister Ye Qian: Ye Tian! You killed three clan elders, and your younger brother Ye Mao still treats you like family. With such a good brother, what more could you want? Second sister Ye Rong: Ye Tian, just give your Supreme Bone to Ye Mao and I'll forgive you! Ye Tian: Since you love Ye Mao so much, I'll torture the person you love most to death! The God-Burying Secret Realm, the Pavilion of Banished Immortals. Woman in red: Ye Tian, since you've come, you must become my Dao companion. Ye Tian: I refuse. Woman in red: If you refuse, you'll suffer the backlash of my karma. To sever the karmic ties between us, you must do eight things for me.
