Although Toby successfully defeated the Extreme Resentment Thoughts, this was only the projection of the House of the Heart; it's too early to celebrate. Only by truly overcoming the Extreme Resentment Tribulation can there be a sense of closure.
To increase the likelihood of surviving the trial, Toby resolutely decided to enter the House of the Heart once more. By undergoing repeated trials, Toby could grasp finer details about confronting the Extreme Resentment Thoughts, which would aid in the real trial.
During the previous attempt, Toby's victory over the Extreme Resentment Thoughts was rather precarious. However, there were still nearly twenty Demon Bloodstones remaining, many of which were of premium quality. Toby believed that by exhausting these resources, there was a chance to decisively crush the opponent during the actual confrontation.
Yet, as Toby eagerly prepared to Enter Dream again, Greya stopped him in his tracks.
