Gaven pulled out a translucent coil from his chest.
It was none other than a collar made from the silk of a phase spider, attached to a small otherworldly dimension hole.
However, it wasn't a brand new dimensional hole, but a clone created through the special ability of his portable dimensional hole, a typical mother-child hole that could control the child hole through the mother hole, but the child hole could not affect the mother hole.
Gaven planned to use it as a mail system for different worlds, so he could keep real-time control of the situation in his domain.
He had only just created it two days ago.
The phase spider silk naturally came from the City of Brilliance auction house, at an outrageous price. There were only three strands discovered there: one priced at eighteen thousand gold coins, another at twenty-five thousand, and the last at fifty-eight thousand, purely seeing people as sheep to be slaughtered.
