While Black Dragon was still bewildered, Lin Feng spread his spiritual sense.
After getting his bearings, he shot toward the Purple Cloud Palace.
Before long, he set the thoroughly confused Black Dragon down.
Then he summoned his flying sword again and slashed it through the air!
A spatial rift appeared.
Lin Feng's flying sword merged into his body once more.
He reached forward with both hands and tore the spatial rift open.
Then he slipped inside.
His figure flashed as he achieved Human-Sword Unity and hurtled upward toward the Fourth Heaven.
Soon, he felt a far denser emperor's might rushing toward him.
At the same time, however, a force of heaven and earth resisted him, preventing him from entering the Fourth Heaven.
"It seems this is the boundary of the Fourth Heaven!"
Lin Feng came to a stop.
Light shone from his eyes as he examined his surroundings.
Invisible strands of the power of heaven and earth formed something like an enormous net, barring cultivators from the Third Heaven from entering.
He threw a punch, his fist colliding with that invisible net.
Tremendous force surged forth.
The impact made the net woven from the power of heaven and earth ripple and shake incessantly!
But after a while, the net dispersed his force through its vibrations, dissipating the power of Lin Feng's punch.
In the end, it returned to its original state.
"No wonder those in the early-stage Heavenly Emperor realm can't break through the boundary and ascend. Even someone who has just entered the Emperor Venerable realm probably couldn't break through this restrictive seal!"
Lin Feng looked at the net of heaven and earth's power, pondering.
According to the ghost creature Xiang Tong, the people in the Fourth Heaven had worked together to shape the power of heaven and earth
