Xu Tui had always wanted to know how the Muya Expeditionary Force would pass through the high-temperature fire wall of the solar system and even reach the solar system with the Sun Guardian that Little Six had mentioned.
Xu Tui already knew how the Spiritual Race crossed it through Yanzi. It was an ultra-limited teleportation channel that the Spiritual Race had spent a lot of money to establish. This was how Yanzi had come over back then.
These two planets were respectively named Planet X and Planet Y by the Spiritual Race. They were extremely mysterious.
Even Yanzi, who had walked past once, did not know the exact location. No matter what, there were still many restrictions on the passage of the Spiritual Race.
