When Jiang Lan woke up, she found herself seriously injured, but with a beautiful aunt by her side.
After awakening his memories, he discovered that this was a world of spiritual resurgence where ferocious beasts roamed and human life was as cheap as grass.
Here, ordinary people can only become lowly laborers, while only martial artists can control life and death, and even burn mountains and boil seas.
Fortunately, Jiang Lan awakened the martial arts gacha system and drew the Vajra Indestructible at the start, which can be continuously upgraded.
"Ding, congratulations host, you have reached the first level of Indestructible Vajra. Your skin is beginning to harden."
"Ding, congratulations host, you have reached the 500th level of Indestructible Vajra. Enemy attacks on you are like scraping a gua sha."
"Ding, congratulations host, you have reached the first thousandth level of indestructible Vajra, and you are now immune to forbidden spells and magic."
"Ding, congratulations host, you have reached the 100 millionth level of Indestructible Vajra, and your health is ∞ points."
