If Ye Feng harvested the entire middle area once, it would take approximately 10 hours, which means he could gain 6 billion points of Spiritual Energy in one go.

Moreover, Ye Feng wasn't employing a plundering method of harvesting Spiritual Energy, but rather a normal harvest, just like the trees in the outside world.

Therefore, depending on the situation, the trees could recover their internal Spiritual Energy in three to four hours at the fastest or seven to eight hours at the slowest.

In other words, if Ye Feng wanted, he could continuously cycle through harvesting here.

Of course, Ye Feng wouldn't do that.

Under such circumstances, he had to concentrate fully to do so, which meant he couldn't afford to be distracted and do anything else while harvesting Spiritual Energy.

So for Ye Feng, it was enough just to have what he needed.
