Wu Ping tried to enter with a trace of curiosity.
However, when he entered, the scene in front of him suddenly changed.
Everything around him changed.
This place was already in ruins, and there were tall buildings everywhere.
He looked at the skyscrapers of the city.
Wu Ping was in a good mood.
Could it be that he had returned to his previous life?
If that was the case, then he would be the only self-cultivator in this city.

Later on, he discovered that the change in this world actually began from the night he entered this space.

"Class [Warrior]+ Material [Gunpowder Crow]+ Material [Coroman Alloy]. Can be upgraded to [Gokudo Warrior]."
……
"Class [Gokudo Warrior]+ Material [Ancient Black Dragon Body]+ Material [Deep Space Type 3 Magnetic Field generator]. Can be upgraded to [Magnetic Field Martial God]."
Lu Biping looked at his body that was gradually covered in black scales. The black wings that covered the sky slowly spread out behind him. With just a slight flap of his wings, he passed through the nine heavens. He could feel that the gravity of the planet could no longer restrain him until he reached deep space.
His long black hair danced in the starry sky without any wind. His scarlet eyes stared at the deep-space mecha that was flying across the starry sky at high speed. He laughed maniacally and muttered in a low voice,"Ha, hahaha... Now... Now it's time for you to know my tolerance!"
