Feng Jun returned to the Blue Star Realm and began a new round of attempts. This time, he was setting up the Mistbound Prison Formation—thanks to Immortal Yan's help, he had finally gathered the materials for the illusion formation.
This prison formation was extremely difficult to set up. He spent a full eleven days and failed nearly twenty times before successfully activating it.
As for its effects, they were genuinely quite good. It consumed Spirit Stones very slowly—naturally, a prison formation needed energy to function, so consuming Spirit Stones was unavoidable. In any case, Feng Jun could not think of a way to replace Spirit Stones with electricity.
After observing it for a full day and night, he discovered that the Spirit Stones within the formation had attracted a trace of spiritual energy. Moreover, with that added spiritual energy, the Mistbound Prison Formation became somewhat more powerful.
His next task was still a heavy one: figuring out how to enlarge the prison formation—preferably enough to cover the entire Bamboo Forest in the valley.
He had very little confidence in that prospect. After all, the previous concealment formation could only be enlarged to less than a hundred square meters. Still, the experiment had to be done, or he would not be able to let it go.
