Breakthrough cultivation & meeting old friend

Waking up on the morning of the new day, Rain stretched and was about to get out of bed as usual, but he felt an inexplicable strength in his whole body. His body seemed lighter, and his movements were no longer restricted.

Chasing away the remnants of sleep and focusing on the changes in him, Rain realized that he had broken through to the next stage!

Now he was no longer in the Spiritual Adept realm, but had advanced to the Inner Balance Expert realm! 

However, there was something that was stressing Rain out.

The day before, he hadn't done anything to increase his cultivation. No, he hadn't cultivated at all since coming to this world, as it required time, and due to the constant events, Rain didn't have any. 

People could spend years to break through from the Spiritual Adept stage to the Inner Balance Expert stage. Even Rain with his talent, without the help of the system, needed at least a month to do so.
