Synopsis of Reborn as the Emperor Armor Summoner
Ten years into the apocalypse, humanity teeters on the brink of extinction beneath a scourge of monsters. Su Chen, an elite superpowered warrior, dies heroically fighting a king-class monster to protect the common people. As he lies dying, the mysterious dragon-shaped jade pendant he has worn since childhood suddenly erupts with light, activating the legendary Emperor Armor System. Carrying endless regret and ten years of combat memories, he is reborn one year before the monsters invade Blue Star.
Back at seventeen, his parents are alive and life is peaceful. No one knows the apocalypse is coming. But Su Chen's soul is now completely bound to the supreme Emperor Armor, making him the world's only true summoner: ruler of the Five Elements, vanquisher of all evil, and emperor of all armors.
With the hatred and bitterness of his previous life, Su Chen is no longer an innocent boy. He learns the armor's powers ahead of time, trains to strengthen his body, stockpiles supplies, builds up his forces, and quietly prepares for the apocalyptic war. When spatial rifts tear open the earth and monsters overrun the cities, plunging the world into terror and despair, Su Chen steps forward without hesitation. Golden divine light shines across heaven and earth as the Emperor Armor roars into place.
From then on, Blue Star has a new guardian who has appeared out of nowhere.
He slays monsters, suppresses evil, saves the people, and displays divine might. With his invincible strength, he sweeps away every crisis, protects his family and closest friends, and rewrites humanity's fate of annihilation. Step by step, he grows from an ordinary city boy into the ultimate emperor, whose presence shakes the heavens and commands the submission of countless races, writing a passionate legend of returning through rebirth to protect the world with the might of an emperor.
Very interesting, the plot is thorough enough
