How Can I Cultivate Immortality Without Relying on Bugs?

I, Qi Yan, have read the script of "a useless person who cultivates immortality" in this life. When my classmates were involved in life and death, I chose to lie down. Until I discovered that this world of cultivating immortals - it has loopholes! While others are practicing hard, I am stuck with a bug. Others fear the way of heaven, but I study the rules. They said I was an alien and a crooked person. Until I used the invincible frame to avoid the powerful spell, I explained with a smile: "This is not a bug, this is a mechanism." (This is a relaxing story about cultivating immortality by relying on bugs.)
