The System Is Invincible, I Will Live Forever, and I Will Be Buried in the Heavens with Ease

Save the Sky System: Host, you are invincible at the same level, hurry up and fight. Li Changsheng: System, don't panic. I use time as a weapon and time as a formation. Isn't this a kind of battle? Heaven-saving system: Host, stop living forever, the sky is almost gone, your immortality is of no use! Li Changsheng: Why are you panicking? Whoever dares to claim to be invincible can be said to be invincible. A dog lives forever, breaks and then establishes the world! My son Zaidao, use your ancient dragon sword to fight against powerful enemies! I am my wife, and I will kill the devil with your golden holy sword! My wife Phoenix, burn your immortal fire to kill evil spirits! My wife, Long Wu, holds your three thousand paintbrushes to pieces and shatters the stars! Billions of creatures are my soldiers, and millions of gods and demons are my generals. Come with me to fight and reopen the world!
