Seven years ago.
Chen Yuan came to the Chizhan Continent from Earth by relying on an ancient teleportation array left on Earth.
But now, going back to Earth no longer requires such trouble.
At that time, he was merely at the peak of Dao Condensation, with strength comparable to the Golden Core stage.
Although he could survive in space, to travel to different realms would have taken decades to centuries.
Thus, Chen Yuan needed the power of arrays to transport himself back then.
Now, with strength comparable to that of a Heavenly Monarch, he could traverse short distances between different realms.
Even if this distance was quite short, mainly in nearby realms, it was still sufficient.
In higher realms, only cultivators with Heavenly Monarch cultivation were allowed to leave their sect to travel and train in other realms.
Many Heavenly Monarch practitioners faced countless calamities while crossing different realms, often meeting their demise.
