Good-for-Nothing from the Start, I Can Freely Increase or Decrease Anything

After Gu Cheng transmigrates to a fantasy world in a car accident, bringing his beloved dog Dahei with him, Daoist Master Xuanxu of the Qingcang Sect takes him in as his last disciple. Unfortunately, Gu Cheng is a good-for-nothing who can't cultivate. Ten years ago, Daoist Master Xuanxu passed away, entrusting the enormous Qingcang Sect to Gu Cheng. Because of his limitations, all the elders and disciples left. Only Gu Cheng and his beloved dog Dahei remained in the sect. “I, Gu Cheng, have disgraced myself as a transmigrator. Master, I have failed you!” During this time, a woman came to break off their engagement, compensating him with a bottle of first-grade Spirit-Gathering Pills. At last, his System interface awakened. The System granted him the ability to increase positive effects and reduce negative ones... See how Gu Cheng relies on the System's support to turn from a good-for-nothing into a rising star... “Every disciple of the Qingcang Sect shall become an emperor!” “At the end of the immortal path, who can stand at the summit? Once Gu Cheng appears, all others are reduced to nothing!”
