Time Deceleration, simply put, could slow one second down to ten seconds, stretch ten seconds into a hundred—this was Time Deceleration.
Any enemy who entered the time domain would be affected by Time Deceleration.
Although the speed of their attacks did not change in itself, because one second became ten seconds, their attack speed would also be reduced tenfold compared to before.
Of course, the Middle Ancient demon Elvis was not that powerful, but he could still slow one second down to three seconds.
Moreover, the applications of these two time laws could be stacked—slowing the enemy down while accelerating himself. With one side diminished and the other increased, the Middle Ancient demon's advantage could be magnified to the utmost.
This would allow a Middle Ancient demon to seize every advantage, something Early Ancient demons simply could not contend against.
"Not good, the consumption is too great."
Yet at this moment, the Middle Ancient demon Elvis's expression changed drastically, and he was filled with horror.
Time Deceleration within this time domain might seem extremely useful, a power akin to a divine skill, but the mana it consumed was simply far, far too immense.
If it were merely binding an ordinary creature, the expenditure might not be too great.
But what Elvis was binding now was the World Tree. Even though it was still only in its juvenile state and nowhere near its prime, it was not something that could be bound whenever one wished.
When Elvis's time domain covered the World Tree's hundreds of millions of roots, it was equivalent to using the time domain to place countless worlds under Time Deceleration.
Simply causing one small world to undergo Time Deceleration was already terrifyingly costly.
If hundreds of millions of small worlds were made to experience altered time flow simultaneously,
