In that lifetime, the national treasury in the imperial palace had a collection of 40 to 50 years old Blood-Heart grass. Mo Wen remembered that the best stalk was only 145 years old and had been deemed a precious treasure of the emperor and was not easily shown to people. Even he had only seen it from afar before.
The older a Blood-Heart grass, the stronger its power.
Legend had it that if a Blood-Heart grass grew to a thousand years old, it would be called a celestial grass and had the ability to control life and death. It had the ability to save people from the brink of death and it was even said that consuming it would allow one to directly ascend to heaven and become immortal.
Even though these were all exaggerated rumors by people and could not be taken as the truth, the extent of the miraculous effect of the Blood-Heart grass was evident. Whether it was in the martial art Jianghu or the medical sphere, the Blood-Heart grass was an uncontested sacred item.
