Lin Tianchou, an orphan from Blue Star, scrapes by amid the steel and concrete of the city. The grind of working nine to five cannot wear away the kindness in his heart. One stormy evening, he rushes to save a child running into traffic and is struck by a runaway truck. As he lies dying, all he can think of is his longing for a home. When he opens his eyes again, he has become the legitimate son of the Lin family in Qingyang County, Canglan Continent, in the mortal realm. He now has a gentle, considerate mother, Liu Yuru, and a steady, fiercely protective father, Lin Xiaotian. These parents, something he never had in his previous life, treasure him and hold him in the palm of their hands.
This is a world where martial arts reign supreme and the strong prey on the weak. Spiritual power abounds, sects stand everywhere, dynasties rise and fall, and human lives are as worthless as grass. Lin Tianchou has no System to bolster him and no golden finger at his side. All he has is his determination to protect his family. Bringing the survival skills of his previous life with him, he is forceful, decisive, and clear about gratitude and grudges: if someone treats him well, he repays them generously; if someone wrongs him, he eradicates them root and branch. Starting with Qi Refining, he advances one bloody step at a time, laying a solid foundation, comprehending the sword, and weathering trials of life and death as he ventures into secret realms, battles powerful enemies, and breaks through the firmament.
From the upheavals of Qingyang on the Canglan Continent to the races at war in the Spirit Realm, the ancient secrets of the Profound Realm, the battles for supremacy across the Immortal Realm, and the contests among the gods in the Divine Realm, Lin Tianchou never stops moving forward. He wields his sword only to protect, and pursues his Dao only for his family. Along the way, only Su Qingyao, the Holy Maiden of the Azure Cloud Sect, stays by his side. From their first meeting to growing close, from fighting side by side to falling deeply in love, they face countless dangers and never leave each other. In the end, Lin Tianchou ascends to the peak as Divine Emperor, protects his family and keeps them safe, takes command of the order of all worlds, and writes an extraordinary legend as an ordinary transmigrator.
