The Tower of Infinity appeared, and the invasion of the second dimension began. Ultimately, the Republic of Korea collapsed, and the world perished. Kim Sang-hyuk, dying after losing everything. The last thing he obtained was the <Heart of the Demon Dragon of Apocalypse>, which had destroyed the world. And when he opened his eyes again, he found himself back before all the tragedy began. A regressor who knows the future. The power of the Demon Dragon that brought the apocalypse. This time, he will seize every opportunity within the Tower of Infinity to prevent the impending invasion of the second dimension and destruction. To rebuild Ilseong and the Republic of Korea from collapsing. ‘In this life, nothing will be taken away from me.’
