The Backline God of War in the World of Immortality

The enemy has few people, so sneak attacks and formations can be done according to convenience. There are many enemies, so shake them, form a formation, and crush them however you want. Well... I'm standing in the back row. I know powerful spells and long-range flying swords. In the same realm, I will definitely be farther away than you. Xia Zhiqiu, who was reborn, knew this truth from birth. The history of human weapon development in previous lives was a long process. From hand-to-hand combat to cold weapons such as swords, bows and arrows, and catapults. To thermal weapons firearms, cannons, missiles, rockets. All are illustrating this truth. You can also cultivate immortality! Bring it on! Demon cultivators! Bring it on! Enemies! Let you see what long-range fire coverage is! Not only can I fight, but there is someone behind me who is just an immortal! Who is afraid of whom!
