Magic weapon ability: it is the sum of all the attributes of magic weapon after blood refinement.

Length: the growth degree of each magic weapon.

Jade expansion and magic weapon expansion: after the magic weapon finalization stage is completed, in order to improve the magic weapon ability to a certain extent, you can buy it in the treasure house of heaven and earth and read jade in the Heavenly Palace (all jade with related attributes can be exchanged, similar to changing fairy beans for jade and exchanging it in the small ring). A 9 attribute (attack, defense, blood, qi, resistance) can increase the upper limit by 10 times. Take resistance as an example. Generally, 30 points of resistance can be added on the basis of existing capacity. Full-scale development needs 180 spindles.

Note: Jade expansion itself only increases the upper limit of magic weapon ability, but does not increase the value. It needs to be improved through blood refining.
