Starting in the Demon Suppression Prison, I Can Modify Cultivation Time

Shen Che transmigrated to a high-martial world rampant with demons and monsters, becoming an intern Demon Suppressor in the Demon Suppression Division. He was immediately sent into the Demon Suppression Prison to personally slay a demon and activate his system. Inside the prison, demons roared, and his colleagues turned pale, but Shen Che remained calm. The moment he beheaded the first demon, a mechanical voice finally sounded in his mind: "Slay demons to gain Time Value, and instantly modify the cultivation years of your techniques!" Others toiled for decades to master the <Golden Bell Shield>, but with a thought, he reached the thirteenth layer of perfection! The incomplete <Black Tiger Saber Technique>? Modified! He instantly comprehended the nascent form of Saber Intent! While others struggled to break through to the True Meridian Realm, Shen Che gazed at the system panel, lost in thought: "How much Time Value does it take to modify the <Dragon Elephant Prajna Skill> to the thirteenth layer?" That day, his fists struck like dragons, his saber's malevolence like tigers, and he carved a path out of the Demon Suppression Prison, becoming the sole demon of this era.
