After dealing with his last Heart Devil Tribulation, Wang Wei knew he was ready for the next stage of cultivation. So, he did not waste time and continued his seclusion.
The first step to entering the Void Shattering Realm is to pass through the [Road of the Heart]. And to do so requires cultivators to enter a profound realm of meditation, unlike anything they have experienced.
Then, they have to understand the concept of emptiness, which does not refer to the state of nothingness but the idea that there is a distinctive idea between how things are and how they appear.
Cultivators must understand the meditative method that focuses on perception and how cultivator views the world and their experience. Cultivators have to look at the world with no preconceived notions or bias about what they think it is or functions; they have to look at the universe through a "void" or "empty" mindset, then they can find the [Road of the Heart] and discover their true self.
