Dungeon Invasion? I Backhandedly Popularized the Immortal War Artifact

In a parallel world, Blue Star is invaded by mysterious things! Human beings in this world can awaken their talents when they reach adulthood, ranging from F level to S level! Some people develop rapidly in this battle, triumphant all the way, and have unlimited glory. Some people are silent, scattered and turned into mud, no one cares about them. Ye Su traveled through time and awakened the counter-war weapon manufacturing system at the beginning. As long as the weapons he sold caused damage to strange monsters, he would continue to receive system rewards. Thus, a massive weapons popularization plan began. … Beauty goddess: "Hurricane Dragon? It's so useful!" The aloof school belle: "This Titan Twin Star is much more effective than my S-level talent!" Abyss Witch: "Stop fighting, we are really going to exterminate the clan!" Succubus: "Close the door quickly! That guy Yesu is here again!" Empress of the Void: "I will never forget the sacred bell that spans the sky and the earth, and the ancient god who holds the sky and steps on the earth!!" Shameless netizen: "I have no money to fight against Kompany!!!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
