Signing In: From Lowliest Laborer to Mightiest Master? SIFLLTMMF

Having transmigrated into a world of cultivation that was full of monsters and devils, Jiang Chen became the lowliest labor slave of a sect.
However, in the Skyfire Sect, there was treasure to be found everywhere!
Signing in at the Myriad Flames Cave, Jiang Chen obtained the "Authentic Solar Fire".
Signing in at the Alchemy Hall, he obtained the "Fire Dragon Body Forging Pill".
Signing in at the Forging Hall, he obtained the "Seven Birds Five Fire Fan".
For 300 years, Jiang Chen hid his strength, sometimes becoming a mysterious master teaching techniques, a secret samaritan aiding justice… all this while continuing to sign in at the Sect to receive prized pills, terrific techniques, and more.
One day, the demonic ancient master Zheng Dao exited his seclusion and attacked the Skyfire Sect, with the goal of taking over the world.
His strength dominated over everyone in the Sect… until he met Jiang Chen who was making a fire.
