"Okay, let's test the mist and fire cannon duo technique on a real target and see how it works." Leng Pan agreed immediately because she could feel that she was running low on spiritual power to support the mist barrier covering the two vehicles and the two of them who were still fighting.
Physical exhaustion could also lead to faster draining of energy. Therefore, it was better to end the battle quickly.
After they agreed on the method of attack, Leng Pan began to form a tunnel made of mist that was about three meters long. It was also very narrow which would increase the pressure inside. The higher the pressure, the faster the fireball would be propelled once it entered the tunnel.
While Leng Pan was constructing the tunnel, she didn't stop killing the zombies near them, and neither did Lu Zhen, even though he was also busy compressing a fireball.
