The most common prohibition spells are used for encrypting jade slips.
The look of joy on Chu Ning's face was because he thought of Zheng Qingmin's jade slip, which his divine sense could not penetrate due to a prohibition spell sealing it.
To break a prohibition spell, there are only two methods, one being an overpowering of strength, that is, forcefully cracking the prohibition.
This kind of forceful cracking requires at least a difference of two minor realms.
In other words, a prohibition laid by an early-stage Golden Core cultivator would, at the very least, require a late-stage Golden Core to break it forcefully.
The other method is mastering the specific technique to break the prohibition. If the prohibition secret technique recorded in Wang Sen's jade slip is the same as that on Zheng Qingmin's, then as long as he learns that secret technique, he would be able to open Zheng Qingmin's jade slip.
