Ever since the Observer established a stable spatial channel between the Hub and Tanagrus Planet, Salamander and the Guardian Legion under his command had been making frequent trips between the two places—not only because the soldiers of the Guardian Legion wanted to visit the legendary "Land of Revival," but also because of the invitation the Observer had extended to them.
The original Guardian Legion had remained stationed in X Sector for the sake of their mission, paying no attention to the outside world for tens of thousands of years. But now, the greatest crisis threatening the Hub had been resolved, and the "Lord of the Throne" they had been waiting for had arrived. On top of that, Hao Ren and the drone legion under his command had taken over most of the defenses within X Sector. It could be said that there was no longer any need for the mission to continue—or at least, there was no need for the entire Guardian Legion to remain there. As a result, a large number of Salamander's men had been freed from their original duties.
And the other regions of the Dream Plane happened to need the strength of these Guardian Giants.
Tanagrus's ecological protection, the engineering projects at Sulun's Gate, the surveys of ecological planets discovered throughout the Dream Plane, and the excavation and research of the Creator God's religion, ruins, and relics—all of it needed manpower. The chaotic Dream Plane needed people everywhere to restore order and rebuild the ruins. Although Hao Ren's unmanned mechanized legion could handle most of the work, the drone legion was ultimately a group of cold machines, and it lacked an understanding of the Dream Plane's "local conditions." Thus, every part of this universe had been suffering from a severe shortage of manpower.
