Lord of the Great Dream

"Master of the Great Dream"
(Cross-Dimensional Trading, Dominating the Universe, Dream Travel)

Li Xuan is diagnosed with a mental illness!
The reason? Two months ago, he began having nightmares, and whenever he falls asleep, his consciousness enters another parallel world.

In this world, an apocalypse has been ravaging for two full months.
There’s another man named Li Xuan, who, in the midst of the end-of-world calamities, has endured extreme cold, heat, acid rain, earthquakes, volcanic eruptions, virus infections—and most terrifying of all, the outbreak of zombies.
Order has collapsed completely, laws are nonexistent, and morality has been ruthlessly trampled.

For two months, Li Xuan has been struggling to survive in the apocalypse, while the urban Li Xuan has been tormented by nightmares for the same amount of time.

Finally, when the apocalyptic Li Xuan unexpectedly kills his first zombie and consumes its crystal core, his spatial powers awaken.
The next morning, when urban Li Xuan wakes up, he is shocked to find that this wasn’t just a dream.
The gold and jewels he stored in the space are truly tangible and can be retrieved in reality.

Similarly, the pork ribs, bread, instant noodles, fruits, and water he bought in the city can also be stored in the space.
The two Li Xuans from different parallel worlds can share resources with each other through their dream space.

What does this mean for Li Xuan?
