Immortality: Starting from Killing Demons and Krypton Life

In the Zhou Dynasty, demons brought trouble to the world and the people were in dire straits. Mo Chen, who traveled through time, has awakened the Krypton Life System, and can practice martial arts by consuming his lifespan. However, a mortal's lifespan does not last more than a hundred years. Fortunately, after he killed the demon with a swing of his sword, he was able to plunder the demon's remaining lifespan. From then on, he only had to deduce the fate of the Krypton Demon to reach the realm that others had to work hard for many years to achieve in an instant. From [Bath Sword Technique] to [Heaven-Slaying Sword Drawing Technique], from [Iron Cloth Shirt] to [Vajra Immortal Body]... "You become stronger by spending your life, but you spend your own life!" "What's the point of sacrificing our lives!" A group of demons who were scared to death by Mo Chen wanted to cry but had no tears left.
