Summonpocalypse [Apocalyptic Summoner LitRPG]

People die when killed. But what if that was the only way they could die? Immunity from all diseases. Never feeling the adverse effects of old age. Invulnerability from all forms of harm, from everything between stab wounds and falling from great heights. On just a random day, all of humanity received what many would have usually considered a true miracle. Were it not for the single exception included, however. As worlds collide to form an interdimensional coliseum, every human alive becomes a Summoner. Each person is given a Summon by the System, and it is these Summons that act as the sole way a person can be killed. Only Summons can hurt other Summons, and when one dies, so does its master.  Mike is just one individual in this bloodbath of epic proportions. At his side is an angelic Summon clad in golden armor, an embodiment of Justice! And if this celestial being is good at one thing to keep both itself and its master alive… It’s bringing down holy fire, creating golden weapons, and a whole lot of boastful laughter.
