The male protagonist accidentally discovers that the wardrobe in his home leads to the Cultivation World. Upon his first entry, he is treated as a mining slave and almost loses his life. He brings the secret back to the modern world and, utilizing technological power such as exoskeleton armor and plasma weapons, returns to the other realm to successfully revenge and bring back spiritual medicine capable of curing terminal illnesses. Afterward, he establishes a base in the Cultivation World, uses the laws of physics to crack formations, repels the Myriad Immortals Alliance and divine realm messengers, and rescues 100,000 forced laborers, promoting resource integration between the two worlds. Ultimately, he activates an electromagnetic jammer to shatter the fake Heavenly Dao's conspiracy, bringing about peaceful coexistence, shared prosperity, and joint development between the Cultivation World and modern civilization.
