After Mo Shen stabilized, he refused to let Jiang An find the grass no matter what. They had only found such a thing a few hundred years ago. It could almost be considered a legendary herb.
Even the Mo family did not record this herb. It was obvious how difficult it was to obtain it.
There were naturally many magical herbs in the world, but not all of them could be recorded by the Mo family. The reason was that it was too difficult to obtain.
Although there was no lack of people who had found and verified the medicinal properties of these herbs, they had paid a huge price. Many people had even exchanged their lives for a herb.
Even if herbs could save lives, it was not worth it. The ancestors of the Mo family did not want to see such a thing happen again and did not allow the Mo family's herb record to record such herbs.
