Look at personal preferences, if you like the three skills behind PK, choose brute force Yangchun and unseal. If you like FB, it's quite a monster. If you are a swordsman, it is of little use to force Yangchun to unseal the seal. If you are in other professions, you should choose to study PK. In fact, it is even more useless if the role has a high level. Although Yangchun and Kaifeng can't reach the second solution, they are not bad. Now the mainstream PK pet, thick and ripe, is suitable for low-level swordsman belt.
