This bacterium can form a complex with the larvae of the ghost moth.

Yun Duoduo pondered, this thing does indeed look like cordyceps.

However, Cordyceps sinensis mostly grows in high-altitude, cold mountainous areas at an altitude of 3,000-4,000 meters, primarily in the soil of grasslands, valleys, and meadows.

In their previous lives, they were mainly distributed in the high-altitude and snow-capped grassland areas of provinces (autonomous regions) such as Tibet, Qinghai, Gansu, Sichuan, Guizhou, and Yunnan.

Why would this thing appear in the Shu Kingdom?

The Shu Kingdom was located in Sichuan...

Yun Duoduo immediately became interested in Medicine King Valley, as well as the person who delivered the letter to her.

Cordyceps sinensis is a wonderful thing; it is ranked alongside ginseng and deer antler as one of the three major tonics.

It can nourish the kidneys and lungs, stop bleeding and resolve phlegm.

It is used for kidney deficiency and essence depletion, impotence and seminal emission, soreness and pain in the waist and knees, chronic cough and wheezing, and cough with hemoptysis due to overwork.

This is absolutely a rare find.

Moreover, she had never seen this thing before, even in the Imperial Hospital. She never expected that the people from Medicine King Valley would give her something so valuable.

Yun Duoduo planned to take the cordyceps back first, and then think about these things when she returned to the palace.

Just as her hand was about to touch the herb, she suddenly noticed that the top of it was somewhat black.

Actually, it's normal for the top of cordyceps to be dark brown; however, the tops of the cordyceps in this box are a bit too dark.

Yun Duoduo carefully picked one up, smelled it, and then took out a silver needle to test it.

[This is... Black Poison?!]
