Finally, aside from these three requirements, to ensure the growth and maturation of rice, it is essential to use fertilizer made from composted beast bone powder as nutrients throughout the process.
These four requirements alone determine that the regions suitable for growing rice are exceedingly rare.
Indeed, this is the case; the entire Chen Cang has only three areas where rice can be planted, and the Lu River Valley is one of them, albeit the smallest.
The key is that rice not only has demanding growth conditions, but harvesting it is also extraordinarily difficult.
Due to the long-term use of coal for heating, the rice stems and roots are continuously baked, releasing a deadly high-temperature toxin known as Green Fire Poison, named by Chen Cang because it appears green and looks like flames from close up.
