Mountain and River Realm is the cultivation level after Shattering Void Realm.
The so-called consummate level of the Mountain River Tier, is not actually the consummate level. The true pinnacle of the Mountain River Tier is five Mountains and Rivers, not four. Five is the genuine pinnacle of the Mountain River Tier. It's impossible to form any more Mountains and Rivers. This is equivalent to advancing an extra minor tier, and it's the only way to become a 10-star genius.[1]
