Double Penetration of Immortality in the Last Days: I Can Become Stronger by Committing Suicide

Am I actually glad that the end of the world is coming? A trick that cannot be used in Blue Star, but can be used in the world of cultivating immortals! Does it require human life to become stronger as a demon cultivator? The most indispensable thing in the apocalypse is living people and zombies! Traditional tricks have allowed me to shine in another world, and my methods of cultivating immortals have crushed the heroes of the apocalypse. As long as I'm ruthless enough, I can gain a foothold in the new world! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
