I Am Summoning Infinitely in the Spiritual Energy Recovery World

When Mu Yu woke up, he found that he had returned to the day after the spiritual energy was revived. And along with it, there was an eye tattoo that he brought back from the ruins. As the eye tattoo gradually awakens, Mu Yu can summon creatures from other worlds to fight for him one after another. Shizune, Hell Fubuki, Tony Stark... In this way, the legend that one person is a legion slowly resounds in this world where spiritual energy is recovering.
