Arch-Heaven was somewhat confusing. The spiritual energy was abundant, yet the resources were not necessarily all treasures - at least as far as Lex could tell. The soil and rocks were normal, and the trees were far from extraordinary. If he hadn't used arrays and his many means to strengthen his chute, his weight would have been enough to tear it apart, showing that the materials on the trees were far from resilient.
Yet, everything was clearly superior to items Lex had brought from outside Arch-Heaven in a way he could not quite understand. It was similar to how having a Primordial aura made him heavier to the laws of space of ordinary realms. The weight was not his, but of his aura. In this case, everything here was ordinary, and yet superior to things from outside.
For example, Naraka seemed just fine, and could even be strengthened using his sword intent. Yet Lex's deep understanding of the weapon allowed him to notice even the most minute changes.
