Let me explain here that the first three stages of the Golden Core stage are the strengths of people born in the world of cultivation. Not all people in the world of cultivation are at the Golden Core stage or above.
Foundation Building [This level represents the first and second level warriors in the mortal world]
Bigu [the fifth level and the sixth level collectively]
Golden elixir [gathered golden elixir]
Nascent Soul [forming the body of Nascent Soul]
Condensation【Become one with Nascent Soul】
Distraction [The soul leaves the body]
Overcoming the tribulation [It can also be called the period of heavenly tribulation, which requires surviving the tribulation of thunder]
Mahayana [The stage of converting spiritual energy into immortal energy, and after the transformation is successful, you will ascend to the immortal world]
