After Jiang Lu came out of the Tower of Redemption, the smile on his face gradually faded away.
He realized that there was no longer time to waste.
The war in the Underworld would conclude within a hundred years, and a new act would unfold, which would be the best opportunity for him to seize power.
If converted to the real world's time, this deadline was roughly one month.
Jiang Lu did not know how much he needed to improve to take part in that level of struggle, all he could do was seize every minute and second to enter the Spirit Realm and gather as many benefits as possible.
Based on the current pace, it took three to four days to level up from 1 to 12, and in total, he conquered four Spirit Domains, including two S-ranked and two A-ranked.
But the two A-ranked Spirit Domains only contributed four levels, and the rewards were quite standard; the bulk came from exploring areas outside the main storyline of the Spirit Domains.
