I Drove My Master into a Heart Demon

When Situ Feng was just a hair's breadth from falling to demonic cultivation, the only elder left in his clan suddenly found him a master. Situ Feng couldn't tell what this master's background was, nor could he see through his cultivation level. But he couldn't possibly be anyone powerful. The guy didn't have a penny to his name. He ate and lived at Situ Feng's expense, and didn't even know the current state of the immortal sects, so Situ Feng had to explain it all to him. Situ Feng wanted to drive him away. Once his last remaining elder passed away, he would be free to take revenge on everyone who had destroyed his family. He would make them suffer a thousand venomous insects gnawing at their hearts and leave them broken to pieces. But this cheap master was unbelievably patient. Situ Feng gave him a hard time on purpose. He endured it. Situ Feng behaved atrociously. He endured it. Situ Feng caused trouble so enormous it nearly brought down the heavens, getting them hunted every day, and the man still clutched his chest and endured it. Situ Feng: ...Do you have that much of a sense of responsibility? How has none of this driven you away?! - Ji Wuya was a divine lord from the heavens. His entire life had gone smoothly, and he was revered by the Six Realms. Then the sheltered divine lord sensed that the Demon Venerable was about to be born, so he descended to the mortal realm himself to subdue him, only to be saddled with a disciple. Ji Wuya had never raised a disciple before, and his first one was already on hell mode: his disciple was a black-hearted schemer with a corruption level of one hundred percent, but he didn't know it. Every day, watching what his disciple did and seeing that innocent face, the divine lord would clutch his chest as his inner demon gained another point. What could he do? He was a god who saved the suffering, and his disciple was a poor soul with a tragic past, looked down on and bullied by everyone. Even if his inner demon reached one hundred percent, he would keep looking for the Demon Venerable while raising his disciple. But later, Ji Wuya found the Demon Venerable. It was his disciple. Ji Wuya: ... Situ Feng dropped the act and came clean: "Oh... So, Master, are you going to kill me now?" Ji Wuya, whose inner demon had already grown to its full strength from being driven up the wall: "Yes." Then he hoisted his black-hearted disciple over his shoulder. "I'll kill you another way." Situ Feng: ??? You say you're walking through an endless, sunless wasteland of ice and snow. Then I'll be the only sun in your world, lighting your way and melting all the snow.
