The Spirit Void Realm is a minor world. Its maximum capacity limits cultivation to the Mahayana level. Thus, even if the Demon Clan invades, the highest cultivation level they can bring is also Mahayana.
Those with higher cultivation levels cannot enter. Heavenly Immortals who could forcibly break through would battle in the Great Thousand Worlds, monitored by Sect Elders, so there's no need for concern. Therefore, in the Spirit Void Realm, Chen Jiuge, with his Mahayana cultivation, is quite safe, provided he doesn't act recklessly.
This is a world where technology and mysticism converge.
The level of technological development is similar to that of his previous world, except that the most powerful conventional weapon, the missile, only possesses power comparable to the Nascent Soul level, which is rather insignificant.
