Elemental Veins

"Since you don't have any problem, let's begin," I said, and strings began to come out of my hands, and a minute later, they have formed a transparent pink coffin. 

A looked of surprise couldn't help but appear in her eyes. Most people get surprised seeing my coffin; it is quite a strange shape and even creeps to some people, as Elina had said.

"Please get inside," I said. "There is no need for you to take off your clothes; sealing your power and taking off your artifacts are enough," I said; she nodded and walked and deactivated her armor; underneath it is her unform.

She took out her blazer and all the metallic things and artifacts on her body before she stepped into the coffin and lay inside.

As she did, I closed the seal off the coffin, and the seed entered her before extremly fine strings that are invisible to the eyes. These are the finest strings I could make, and I need them to be as fine as possible to do anything to the veins.
