Compared to the martial arts, heavenly materials and earthly treasures, and teleportation he had previously manifested and which could affect himself, the scarcity of teleportation was undoubtedly much higher. The key lay in the fact that in his perception, the High Martial World lacked any superpowers, which meant that his fantasy materialization was not limited to just the concept of 'martial arts'.
Although he had previously materialized drones and satellites, technological creations that also did not exist in the Otherworldly, the difference was that these objects existed in the real world. Moreover, he obtained genuine, fully functional technological creations, which had a relatively reasonable basis... it was just relatively reasonable.
Thus, this success was akin to a conceptual upgrade of 'The Galaxy is also a River'.
[Is this how fantasy materialization should be used?]
