After sensing a threat from the timeline, the Black Mountain Goat left Beta Town. Instead of retreating to the depths of the Silent Forest as initially planned, it followed an instinct from the old days, traveled up the Silent River, found a vulnerability in the First University's Guardian Array, and infiltrated the institution's Lin Zhong Lake.
Fortunately or unfortunately, shortly after entering the lake, the Black Mountain Goat saw a Green Vine sprouting from the lake water, rooting itself between illusion and reality, connecting the two worlds.
Fortunately, the moment it saw the Green Vine, the Black Mountain Goat knew what to do—follow the path opened by the Green Vine, and reverse into the Dreamland to evade the pursuit from the timeline.
Unfortunately, a little Female Demon emerged from the Green Vine, drawing the focal attention of the School Guardian Array.
