After transmigrating into the world of Mr. Vampire in the Republic era, Lin Chen becomes the third disciple under Uncle Jiu and unexpectedly obtains the Divine Light Rod of Tiga.
New to this world, he's firmly constrained by a three-minute transformation limit. Faced with zombies, vengeful ghosts, and evil spirits wreaking havoc in a turbulent age, all he can do is grip the light in his hand with all his might, learn Maoshan Daoist arts from Uncle Jiu, and protect the people of Ren Family Town.
The Blackwater Flood Dragon, the thousand-year-old Ink Flood Dragon, the Dark Church, the King of Ten Thousand Souls and Zombies... Through countless battles to the death, he fully merges his Maoshan pure-yang cultivation with the power of light. At first, he can only maintain his full-sized transformation for eight minutes; in the end, he breaks the three-minute limit, unites his heart with the light, and achieves limitless stamina.
He guarded Ren Family Town all his life and protected the banks of the Yellow River for half a lifetime. Dying peacefully of old age wasn't the end: the light fused with his soul carried him across the barriers of time and space.
He entered the Ultraman universe, helping Kotaro understand the true meaning of light and helping the lone fighter Gen emerge from the darkness. At the final hour, with Gatanothor closing in, he kept the hope of light alive for children all over the world;
He returned to the mortal world, accompanying tomb raiders on eight perilous journeys: breaking the thousand-year-old curse of the Ancient City of Jingjue, braving the insect-infested forbidden grounds of Yunnan's Worm Valley, settling the century-old grudge at Pingshan, and unraveling the mystery of the Guan Shan coffins at Wu Gorge.
From a small country estate in the chaos of the Republic era, to the vast sea of stars in the Land of Light, to perilous secret places across the length and breadth of the land, Lin Chen never changed.
He was never some cosmic hero, just an ordinary man holding the light.
As long as there are warm hearths in the world, people in need of protection, and those who still believe in the light, he will keep moving forward, and his light will never go out.
