"Soul Integration"

Noticing this new discovery, Jake was stunned for a few seconds before he looked at the 'loosening' barrier. 

To be honest, he thought that the cage would be so tough, but in reality, it wasn't like that. 

There were loopholes everywhere, and the barrier itself was, at most, elastic. It wasn't solid and tough like a wall. 

This discovery undoubtedly relieved Jake's anxious heart, and the man quickly held his breath before kicking or punching the barrier once more. 

Since his physical action of kicking and punching the wall was actually the same as forcefully breaking free from Zenith's control...

Jake believed that once his consciousness left this dark place, he might be able to take control of his body within seconds. 

But Jake was also cautious because if he left the cage, what if the celestial noticed this and manipulated him once more? 

After knowing that he could break free, wouldn't the next manipulation be even stronger?
