I Use a Power Bank to Cultivate Immortality

Ni Kun prepared for three years, and everything was complete including talisman paper, cinnabar, and peach wood sword. He even spent all his savings and bought a secret book on "100% time travel success" from the Internet. On the day of the time travel, he set up his formation, finished reciting the incantation, and his vision went dark—— When I opened my eyes again, it was still my rental house. Time travel failed. But a voice sounded in my ears: [The system of cultivating immortals has been bound, and the host remains on earth. Please start cultivating immortals. Ni Kun:? ? ? Cultivating immortality in this world without spiritual energy? System: [Reiki substitute - electric energy detected. The host can cultivate immortality through charging. Ni Kun looked at his mobile phone with only 19% battery remaining and fell into deep thought. So, he began to recharge his batteries and cultivate immortality. Others work overtime to make money, while he works overtime to recharge. When others fall in love, he looks for a quickie. While others buy a house or a car, he buys a power bank. For a fee of 60 cents, he went from the first level of Qi training to the ninth level of Qi training, which cost him half a month's salary. Until one day, his mobile phone ran out of battery, and he casually used a "Thunder Jue" to charge it—— There was a loud bang and the whole city lost power. Someone from the National Ability Bureau came to the door: "Comrade, come with us." Only then did Ni Kun realize that he was not the only immortal cultivator on earth. And the guy who calls himself "Thunder and Lightning Dharma King" is looking for him all over the world - not because he stole electricity, but because the system in his hand hides a secret that can subvert the world.
