After descending to the lower realm, the two searched for some time before finally finding the Qingqing Continent. They soon made their way to the Tianlan Grassland.
Although the Tianlan Tribe had been exterminated long ago, the Tingyun Kingdom that had destroyed it still existed, as did other forces on the grasslands that had carved up the Tianlan Tribe's territory.
Some of those forces had undergone repeated changes and already vanished into the river of history, but races like the Giantwood Tribe still occupied those lands.
With the methods available to the two of them, through Soul Searches and examination of the various recorded jade slips and ancient texts held by those forces, a trail of clues gradually surfaced.
Of course, throughout this process, they did not dare act as unscrupulously as Elder Hao. When a Soul Cultivator wanted to kill, he would slaughter every high-level cultivator of an entire race.
Even the Yin-Yang Chaos Sect, when operating in the lower realm, had to assess the specific circumstances before deciding what methods to employ!
Although the two from Luo Gucheng had lived in the upper realm for so long, they had never once come to the lower realm.
Yet they knew the rules governing cultivation like the back of their hands and understood clearly what restrictions existed within the Immortal Realm's order in the Mortal Realm.
Therefore, before investigating any information, they would first inquire clearly into exactly what sort of force stood behind the other party.
In particular, the top forces on every continent in the Mortal Realm simply could not be touched lightly. Unless absolutely necessary, they would resort to other roundabout methods.
The Tianlan Tribe had been exterminated because, back then, Amuer and the others had indiscriminately slaughtered innocent mortals, provoking the joint assault of numerous forces.
