264 Cardinal Forbidden zones.

The dragon on the door was what was called a Precious Spirit.

Precious Spirits were as their names implied. There were made by mending the reminant spiritual energy of many strong ancestors.

This required a special method for it to work.

The Precious Spirit is born with a seperate personality but the same memories as contained in the spirit energies.

At a certain stage in cultivation, one starts to cultivate not just spiritual energy in the body but also spiritual energy in the heavens.

This incites heavens rage and a cultivator will have to face an heavenly tribulation.

When a Precious Spirit is made, it comes with a Precious Land.

A subspace different from the known world.

This was usually a land rich resources.

But there was just one problem.

The Precious Spirit was made from spirit energies of cultivators that have already touched heaven's spiritual energy.

Meaning that they also attracted heaven's tribulations.
