The modern genius painter Lin Zheng was accidentally bound to the "Painting Realm Shuttle" system and was forced to travel across the world. Everywhere he goes, he needs to complete specific painting tasks in exchange for a chance to return to reality. From the world of immortality to the base of the apocalypse, from ancient rivers and lakes to urban campuses, he used his paintbrush as a blade to shuttle between different civilizations. When he first entered the world of Canglan, he found himself in a useless situation. He was bullied by his fellow disciples, his spiritual stone was cut off, and his life was hanging by a thread. The system was activated and the aura pen appeared. He used spells to repel the enemy and relied on his painting skills to break the situation. The sect became famous in the first battle, but was involved in the shocking conspiracy behind the mountain-protecting formation. The road ahead is full of dangers, and the road back is far away.
