Because in the algorithm Su Yu deciphered at the beginning, there was a special string of numbers, which was the Emperor's exclusive numerical mark, containing supreme significance and power.
The so-called Emperor naturally refers to the Radiant Emperor, which is why the Galaxy Battle Armor and the "King" were so frightened back then.
At that time, the algorithm Su Yu deciphered was merely the route algorithm given by the Star Tower after scanning the Manifestation Space, containing all the entry and exit routes of the Manifestation Space, akin to an "offline map" of the Manifestation Space, useless once outside of it.
But now, with Su Yu's fusion of the navigation device's abilities, the obtained algorithm is much more powerful than that offline map.
It can directly interpret Star Tower signals, even using them for map scanning and route planning.
