Versatile Mage: Mechanical Summoner, I Summon the Gods

[Multiple Heroines] + [Invincible] + [Numerous Machines] + [A Somewhat Slow Plot] Tang Yu transmigrates to the world of Versatile Mage. He becomes the adopted son of Tang Zhong. At sixteen, he awakens the Summoning System, only to discover that his past life’s Mechanical Heart lies within his star cloud. The Mechanical Heart is both a vessel and an innate talent. The bad news: I’m locked into the Summoning System! The good news: I’m about to bring down divine machinery! Tang Yu can use essences to exchange for all kinds of machines from the Mechanical Heart. Mechanical beasts, humanoid machines, mechanical magical tools, and more. Basic machines: Fire Fox Guerrilla, Heavy Machine-Gun Fang Mechanical Wolf, Gale Shooter, Night Hunter... Intermediate machines: Lava Sabertooth Tiger, Lightning Feathered Serpent God, Judgment Angel, War Greymon, Angewomon... Advanced machines: Hive Destroyer, Destruction Titan, Gardevoir, Charizard... During the Bo City disaster, he unleashes a steel tide of mechanical beasts to slaughter demons and wipe out the Winged Azure Wolf! During the Ancient Capital crisis, he erects countless defensive towers, creating interlocking fire, saturating the battlefield, successfully dons the armor robes, and takes control of the underworld. Looking back, the Magic Plane, Dark Plane, Summoning Plane, and all the rest lie beneath his feet. Tang Yu: “Machinery plus magic, boundless magic power! Even gods have to be afraid!”
