These deformed creatures were bound roughly by Wei Tianyang, and when he touched them, he couldn't read their memories.
When Wei Tianyang touched the Heavenly Falling Objects, he could read their memories. To say that these deforms were more advanced than the Heavenly Falling Objects was nonsense. He hypothesized that the memory abilities of these deforms were as poor as those of fish; thus, they couldn't retain memories for long and naturally couldn't be read.
Of course, this was just his hypothesis. If he couldn't read them, so be it. Wei Tianyang controlled the large iron door, which he had damaged himself, and re-contained the sphere. Afterwards, he returned to the Pei Guode Hotel on his own.
