At that time, while Zhou Tian did experience a slight improvement in his strength during the cultivation process, he felt deeply dissatisfied with the overall situation.
The progress was too slow. Based on the cultivation speed at the time, Zhou Tian might not have lagged behind other deities, but with that level of advancement, it was absolutely impossible for him to achieve the status of a Divine Realm leader.
After all, in comparison to those deities, Zhou Tian didn't have any inherent advantages.
When it came to aptitude, Zhou Tian wasn't just inferior to the deities—he was even worse off than many lower-realm living beings. His ability to grow to his current level was merely due to a series of remarkable experiences that pushed him forward. If not for the countless events that caused leaps in his strength, Zhou Tian would likely have ended up as a minor boss in the lower realm, at best.
