"All of the missions are split into 8 Tiers. The first floor has Tier 1 missions. The second floor has Tier 2 missions. The third floor has Tier 3 missions, etc. Likewise, the seventh floor has Tier 7 missions."
"Tier 1 missions are the most numerous, but they are also easy and give small rewards. They are meant for Spirit Channelling Realm cultivators."
"Tier 2 missions are slightly more difficult and are catered for Physique Transformation Realm cultivators. The rewards are also better."
"The seventh floor's Tier 7 missions are meant for Principle Manipulation Realm cultivators such as yourself. They are difficult, but also have much better rewards and give a higher amount of contribution points."
"Do you know about the Sweepers?" Liu Hao asked Tang Yin.
Tang Yin nodded. The existence of Sweepers was not a secret. In fact, they were well known. All cultivators dreaded the Sweepers.
