Dongfeng asks Lin Hai if he still wants to escape, and Lin Hai says that he does not want to stain his hand with Asura's blood. Lin Hai tells him that the next day, he will use this technique to create a "confederation space" and summon spirits. He tells Lin Hai that he has learned this technique and that it is similar to a "traping formation" . He explains that the reason why secrets are mysterious is that they are not connected to attainments. The confinement space can trap someone like a great saint. He says that even a "basal soul cultivator" can't escape from this confinement space, because he needs an energy source.
