Escape from Earth!

When the blue planet as round as a dew—the third planet of a peaceful, quiet galaxy—gradually appeared in front of Li Yao in a haze again, he was no longer surprised and confused at all. Instead, he was full of relief and expectation after the long wait.

He felt that he was a wanderer that had roamed the sea of stars for thousands of years and that he was about to be embraced by the warm and familiar home again.

Earth, the mysterious homeland that haunted Li Yao's soul!

Did it really exist in a certain space zone in the middle of the three thousand Sectors or somewhere beyond? Was it a certain mysterious, indescribable being beyond the three-dimensional world? Was it nonexistent and just an illusion of Li Yao himself, a malicious joke that certain fiends hundreds of times stronger than the extraterrestrial devils played on him?
