These 18 sword puppets were automatically controlled by the array formation, ownerless objects.
Pang Wannian accidentally activated the array formation previously. That was why these 18 sword puppets attacked the Tranquil Cloud Sect group.
As long as Ye Yuan comprehended the Lesser Nine Revolutions Interlocking Formation fully, he would be able to control these 18 sword puppets!
If Ye Yuan had these 18 sword puppets, he would have the ability to protect himself in front of Sea Transformation Realm experts.
With Ye Yuan's present strength, facing early-stage and middle-stage Crystal Formation Realm martial artists should not pose a problem. But facing late-stage Crystal Formation Realm martial artists would be more challenging.
As for Sea Transformation Realm experts, Ye Yuan virtually did not have any leeway to resist.
