Ironwood Academy [I]

The explosion lasted for a full minute before it stopped, and Fei was already tired and sweating profusely. After putting away the Gatling, the god of fire, Fei shook his head and approached Li Yifeng and Xiaoxue, and sighed. "It seems that my cultivation is still insufficient, and I've already exhausted my mental power after only one minute. An attack with an 'explosive effect' really requires a high-level spiritual master to be able to do it."

At this time, the more than 100 spiritual masters in the stands, including the Xuanbing team, have long been dumbfounded. Although Fei used Vulcan Gatling on the battlefield during the day, he only used that kind of intensive attack method. It was the first time that everyone saw the explosive effect like a fireworks afterward.
