120 seconds!
The time given by the third test gave Xu Tui another surprise. He had originally been prepared that even if he activated all three brands, the duration would only last for 30 seconds. Thirty seconds was much better than ten seconds. If he prepared a few more, he could have a fast-paced battle.
Now, it was 120 seconds.
Xu Tui tested it alone. A single edict with the mark of the Fire Spirit Book could only last for ten seconds. However, with the three major marks on it, the duration increased several times. There was a sense that quantity had a qualitative change.
In Xu Tui's judgment, it should be the combination of internal and external effects that resulted in the overlapping of effects. The branding aura of the Fire Spirit Book was internal, while the two Great Emperor Seals were external.
120 seconds was not enough for cultivation, but it was definitely enough for battle.
