Zhao Hai had been in closed-door cultivation for a full year. In this year, Zhao Hai had spent most of his time in the underground world teaching the Hellfire goblins. The Hellfire goblins were worthy of being called the most suitable race to cultivate fire-type cultivation techniques. In this year, the strength of the Hellfire goblins had increased rapidly. Almost all the Hellfire goblins in the resistance Army had started cultivating, and their results were quite good.
The strongest member of the Goblin race already had the strength of an ordinary unity soul cultivator. Zhao Hai had never thought that he would be able to reach such a level in just a year. This showed how powerful the fire element of the Goblin race was.
