Cultivation of Immortality Starts with Flash Upgrade

Zhou Mingyuan traveled to the world of immortality. Although his qualifications were mediocre, he had his own skill [Flash], and the characteristics of the skill could be upgraded. However, he also understands that his talent is average, a big tree attracts the wind, people are afraid of being famous, and pigs are afraid of being strong, so this skill should be hidden well. Therefore, in front of others, he was kind and gentle, but behind his back, he punched hard, and would not do anything if he could. Once he did, he would flash and run away in seconds. A few years later, in the entire world of immortality, who can still withstand his sap? Flash cooldown: 0s. Flash through walls: 100%. Blink distance: unlimited. Flash Targets: Countless. Zero-cooling flash comes and goes without a trace, 100% flash through walls is equivalent to a universal escape technique, super long-distance flash avoids damage, and flash with countless spells can forcibly kill people in seconds. "Tsk tsk, the charm of numerical values!".
