God-Killing: Agent of Destruction, Kill Them All with One Shot!

[Fan of "Slayer" + the new trilogy of "DOOM" + non-agent (the protagonist becomes Slayer himself) + Hongying selected by God + collision of two world views + various super guns + decisive killing + violent killing of monsters + one person forming an army + demonic war] [And the most important thing: resurrect the Dragon Dragon of "Dark Age"! As a master of DOOM, Lin Feng mysteriously traveled to the world of "Slayer" and owned a [Fortress of Destruction] as a 'gold finger'. He must kill the 'mysterious creatures' in "God Slayer" and plunder their "spiritual power" to recharge the [Fortress of Destruction] in order to gradually unlock: [Combat Shotgun], [Archon Armor], [Heavy Cannon], [Plasma Rifle], [Super Shotgun], [Rocket Launcher], [Vulcan Cannon], [Ballista], [Judgment Sword]. After traveling through time, Lin Feng discovered that the 'demonic' forces from 'DOOM' actually appeared in this strange world of 'God Killing'. The 'Night Watch' has no ability to resist the 'Devil'. From this, he, who started with only a [combat shotgun], gradually became the hope of saving the world. Humans are his 'believers'; Hongying is his 'chosen god'; the 'gods of Great Xia' are his younger brothers; all the evil gods are frightened by this news. Even the protagonist Lin Qiye must respect him ten points, or even nine points. Many years later. Preachers on the streets are all reciting prayers about him: "You will walk in the realm of darkness forever, stand up against evil, and don't care about the fear of others." "May your thirst for revenge never be quenched, and the blood of your sword never dry up." "I hope we never need you again"
