Two years of preparation (1)
In the blink of an eye, two years had passed. It had been two years since Zhao Hai returned to the void realm from the six realms. In the past two years, the exchanges between the six realms and the void had increased. The strength of the six realms had also recovered very well.
Although the six realms had to pay a tribute to the underworld, the number of Tributes was not a lot. It was within the limits of what the six realms could afford. It was even less than the tributes that the ordinary sects of the six realms had given to the six major sects. Therefore, the people of the six realms did not have any resentment.
Zhao Hai had spent most of his time in closed-door cultivation over the past two days. Not only did he study the usage of the laws, but he also studied the various mechanisms, puppets, and arrays he had obtained from the heaven's Secret tower.
