As the believers prayed without cease, Lin Xiao felt a connection gradually emerging between himself and the space where his believers were. As the prayers continued, this connection became clearer, and he felt that if he so desired, he could immediately traverse through this link to arrive at the altar where his devotees were gathered.
But he didn't respond to the believers' prayers right away; instead, he left them hanging to pray with even greater fervor.
Unless it was an extremely urgent situation, he shouldn't descend immediately. A Deity must maintain a certain prestige; three times is the limit, he needed to wait for the believers to pray once or twice more before responding with a descent.
