The reason why Zhao Hai had treated the battle on Warwolf as his first battle was because he had received news that an auction was going to be held on the planet soon. There wasn't anything that caught Zhao Hai's eye in this auction. The only thing that caught his eye was a star map.
The void realm was very large, and each area had its own star map, which recorded all the stars in that area. Some of the smaller planets also recorded the large meteorites in that area, which were the most common things in the void realm, similar to a map.
