According to the standards of cultivation in the Supreme Realm now, unlocking one Physical Body Treasure equates to entering the second level of the Mystical Hidden Realm. If one can unlock the second Physical Body Treasure, it is considered the perfection of the Physical Hidden Realm, progressing into the third level of the Mystical Hidden Realm.
For most cultivators, being able to unlock two treasures is already sufficient.
The rest of their lives could be well spent if they could fully develop and extract the value from these two treasures.
The fewer Physical Body Treasures one has unlocked, the fewer choices one has when entering the Inheritance Mystery Realm, and the lower the chance of becoming entrapped in the realm.
That's why many people, after unlocking two Physical Body Treasures, directly accumulate cultivation abilities and step into the Inheritance Mystery Realm.
