When he wakes up, the young man Ze Yufei discovers that he has somehow transmigrated to Teyvat, penniless and unarmed. In this fantastical world of surging elemental energy and rampant monsters, his only hope is a suddenly bound "Warrior of Light Legacy System"?
The beginner's gift from the start grants him a mysterious power from the Land of Light: the [Specium Ray]!
From then on, the whole feel of Teyvat quietly begins to change.
When Hilichurls charge with their clubs, they are met with the dazzling glow of the Specium Ray! When Abyss Mages smugly raise their elemental shields, an Ultraman Barrier seals them away! And when the resurrection of a demon god brings a world-shaking crisis, the Metalium Ray rips through the sky, becoming another beam of light protecting Liyue!
From Mondstadt's winds of freedom to Liyue's contracts as solid as stone; from Inazuma's lightning of no thought to Sumeru's dream of wisdom; all the way to the frozen throne of Snezhnaya...
Ze Yufei travels and grows stronger along the way. Ultra Psychic Power, Ultra Water Flow, the M87 Ray... All kinds of dazzling skills from Ultraman blossom in his hands, colliding with the seven elements to create incredible sparks.
The setting is attractive. But why can't energy be restored by itself? It can only be restored through some external objects, such as potions issued by the system. This is the first time I have seen it.
