Earth faces catastrophe from both natural disaster and deliberate assault. A shadowy organization called Sha Hai wages war against humanity itself, armed with technology that shouldn't exist. Lei Si, recruited into the Crisis Case Unit, understands that conventional weapons won't cut it. He assembles Tai Ji Ding, an elite squad equipped with cutting-edge exoskeleton armor designed to fight on multiple fronts simultaneously against an enemy that refuses to reveal itself. As Lei Si and his team pursue leads and intercept attacks, they stumble onto something stranger than alien weaponry: human dreams function as gateways to hidden dimensions invisible to the naked eye. The Sha Hai Organization isn't just trying to conquer Earth, they're waging war across realities. What unfolds is a fractured conflict between civilizations separated by incomprehensible gulfs of time and space, where the line between sleeping and waking becomes the battlefield itself. Lei Si must uncover the truth about his enemy before humanity loses its foothold in existence.
