Capítulo 806: THE AWAKENING OF TIME (II)

The reason why they were unable to raise their level as fast is because the energy of the world become more scarce as more people level up. 

Those who were late to the party, slowly found themselves at a disadvantage in gathering energy

It is good enough that the great power restricted some madman who tries to thin the herd by killing those weak people

As for power leveling.

powerful people don't have time to power level each newbie they found. 

After all, if they slacked they too would get overtaken. 

Thus, there is a problem since the energy in the world is not enough for everyone to reach the highest level that they could. 

The source that provide the energy to the world could not regenerate it fast enough to cope with the consumption of energy.

It is fine if there are tens of thousands of people leveling up to Orb Condensing stage.
