This was an opportunity for Xu Huo. Since it was a test left behind by an elder, he could learn from it whether he approached it through control of the Dungeon environment or control of mental power.
The two of them ate out before returning to the Zhuang family home. The Zhuang brothers had gone from being so anxious they were beside themselves, to forcing themselves to endure, and finally to their current helplessness. They had no idea what Xu Huo was trying to do. They wavered between whether he was dangerous or not: they feared that taking action might cause trouble for the rest of the family, but if they did nothing, they worried the little bald boy might be hurt or something else might go wrong.
In short, the two of them regarded Xu Huo like a bomb that could go off at any moment, but they didn't dare set it off preemptively.
Xu Huo stayed with the Zhuang family for five days. It took him that long to successfully use the "Mind-Only Gate" to reach the core layout of the Dungeon environment.
The Dungeon environment had indeed been dismantled, but in a very clever way. It had been divided according to the layout of the house. The rooms where Zhuang Shanbai lived—including his bedroom, living room, and kitchen—formed a single unit, which was also one section of the Dungeon environment. A very thin partition separated this section from the surrounding houses. To put it simply, it was like a layer of gauze, except that the material itself was a special kind of metal.
With the metal partition in place, manipulating power wouldn't affect other areas, and it also took comparatively less effort.
The Zhuang brothers were both Gray Players, but neither of them had strong Evolution powers.
