Meridian Opening

Meridian Opening is the 5th stage of cultivation and is the last stage of the Houtian Realm.
==Summary==
The meridian pathways humans are born with are both too thin and winding around too much. They aren't capable of withstanding the higher speed and density of the Innate realm spiritual qi. Because of this, your body will literally explode if you advance to the Innate realm with your natural meridians.
The goal of Meridian Opening is to reshape and recreate the Meridian pathways in the human body, allowing them to withstand the energy necessary for the higher realms. To do so, you build the new meridian pathways inside your tempered bones, connecting through your transformed tendons and filling it with your condensed blood and qi, essentially unifying all five stages of the Houtian Realm together as one.
Cultivators that didn't choose to temper all of his bones during the Bone Forging Realm will have to create their new meridian pathways outside of their non-tempered bones. This is harder, requires more effort, and more prone to failure.
For ordinary Meridian Opening experts, they were only able to enlarge their meridians three times. After undergoing complete tempering, the limit was usually eight times.
==New Abilities==
Establishment of a Cultivation Bloodline: Starting from this stage, your offsprings will inherit your cultivation which manifests as a bloodline power. They will have an easier time practising your cultivation techniques and their blood will generate a bloodline pressure which will suppress cultivators with a lesser bloodline than them. This is the foundation behind every ancient cultivation clans, their bloodline allows them to easily master their cultivation techniques while the bloodline pressure generated from their blood is so dense it will cause cultivators from humble backgrounds to explode upon contact.
== Bone Tempering ==
Once you reached Meridian Opening, it was impossible to temper more bones. In other words, how many bones you had tempered before that point was set in stone. Your foundation could not be changed.
