"But there's a way to solve this situation, and that's to prevent other humans from ascending, allowing only myself to ascend! Because the level of zombie monsters is related to the average strength of humans, as long as other humans are weak enough to average out my strength, the overall strength of zombie monsters won't be too strong."
"For example, if all humans are at zero-level, zombies are at Level 1, and I am at Level 4. Then I can become the Savior of humankind! Of course, this situation is hard to achieve because others need to survive too, and they will definitely not give up on the chance to enhance their own strength. So, there is another solution in that memory, and that is to create a potion that severely hinders the enhancement of the drinker's own strength, possibly even preventing them from ascending for the rest of their lives. Since I'm unaffected by these things, my strength will soon surpass all humans, zombies, and monsters, becoming the true Savior!"
