Techniques for Longevity

During a battle to defeat demons, a junior brother said excitedly to Xu Qing: "Haha, senior brother, my fire bomb technique can fire 10 fire bombs at a time, killing dozens of demons, isn't it awesome!" Xu Qing smiled indifferently, waved his hand, and thousands of fire bombs blasted into the sky and the earth like meteorites... Another day, Xu Qing looked at the densely packed psychic fighter planes, psychic rockets, and psychic cannons in front of him with a smile on his face, bombarding the intruders - he had already become an immortal, so he still needed to go up by himself? Xu Qing travels to another world, carrying a panel that can make him stronger by slaying demons, and becomes invincible step by step. Until the end of the road, he suddenly discovered—— The so-called immortality is simply a false proposition! It's even more of a Henggu scam!
