In 2187, Earth’s most elite mech unit, the Celestial Stems, discovers an anomalous energy reading while on a routine patrol. Their captain, Lu Tianxing, is a legendary warrior who has perfectly combined the ancient martial art Nine Heavens Heart Method with cutting-edge mech technology. He leads his squad to investigate, only to witness a shocking sight: a group of alien Star Eaters are siphoning energy from Earth’s core.
Federation scientists predict that at this rate, Earth will become a dead planet within a year. Faced with this cataclysm, Lu Tianxing proposes a desperate plan: rather than defend passively, they should strike first. Piloting specially built Star Dome mechs, they will travel to seven legendary energy planets, draw upon their core energy, and forge an ultimate weapon capable of fighting the Star Eaters.
From scorching lava planets to mirror worlds where gravity is reversed, from a void realm governed by quantum entanglement to an eternal domain where time flows at an abnormal rate, the Celestial Stems squad faces unprecedented challenges. They must not only battle hostile alien creatures, but also adapt to each planet’s unique laws of physics, blending traditional martial arts with alien technology to create something new.
As the battles intensify, Lu Tianxing gradually uncovers a shocking secret about the origin of the universe hidden behind the Star Eaters. The seven kinds of planetary energy they are gathering may be the key to unlocking that secret. When the final battle comes, the Celestial Stems squad must make a difficult choice: save Earth alone, or risk uncovering the truth about the universe?
This is a martial arts legend spanning the stars, an epic of courage, wisdom, and sacrifice.
