The fireball suspended in mid-air by Zhou Chao dispelled all the darkness in the cave and illuminated a large area in the deepest part of the cave with bright lights.

Just like the previous experiment, Lin Fei raised his right hand and began to mobilize the spiritual energy in his body to concentrate in the palm of his hand.

A large amount of spiritual energy gathered quickly, and the abundant spiritual energy in Lin Fei's body was rapidly consumed.

It took more than ten minutes to compress the spiritual energy before. This time, because more spiritual energy was mobilized than before, the time spent increased by several minutes.

In about twenty-five minutes, Lin Fei consumed 60% of his spiritual energy, and a pinpoint-sized spiritual light appeared on his hand.

When the pinpoint-sized psychic energy was successfully compressed, the space fluctuation was attracted and then affected, becoming extremely violent again.

After a clicking sound, like glass breaking, the familiar scene unfolded in front of Lin Fei again.

After the black crack appeared, it expanded rapidly, and the compressed spiritual energy in Lin Fei's hand began to be consumed, and it shook violently, seeming to be unstable.

Any situation like this was within Lin Fei's control, so he concentrated on controlling the vigorously shaking spiritual light group in his hand so that he could maintain a steady consumption.

The spatial cracks are getting bigger and bigger, from the size of a palm at the beginning to the size of a football, and are slowly expanding further.

Lin Fei watched the space crack in front of him expand very slowly. He estimated that if it expanded to the size of a millstone, it would still not be able to form a world passage to open up the two worlds. At that time, the compressed spiritual energy in his hand was almost exhausted.

"We still need to increase the output of some psychic energy to turn the spatial rift into a spatial channel."

After this psychic experiment, Lin Fei felt that if he spent more psychic energy next time, he would be successful, so he stopped wasting time and immediately dispersed the psychic energy in his hands and turned around to leave.

Without the blessing of spiritual energy, the cracks in space that appeared quickly dissipated.

After Lin Fei came out of the cave, he came again to the place where his spiritual energy had been restored.

As he began to practice, the spiritual energy floating in the air surged towards his place again, and the spiritual energy was formed in a matter of seconds.

In the past, those strange beasts left because they were worried that unknown powerful beings would eat them if they got hungry after practicing.

Suddenly, they found that the psychic tide appeared again. The alien beasts were stunned for a moment and struggled in place for a while. Then they could not resist the temptation and started running towards the place where the psychic tide appeared again.
