"So that's why it's called Heart Hand!"
This Heart Hand is fundamentally not a technique for processing medicinal materials. To be precise, processing medicinal materials is just one trivial use of the Heart Hand.
The Heart Hand is a type of swordsmanship, similar to the swordsmanship in the "Heart Sword Scripture."
The Jade Scroll that Yang Zhenshan just fetched is the "Heart Sword Scripture," which Yang Zhenshan unintentionally obtained from the Ancient Relic Array. But because he hasn't practiced swordsmanship, this Cultivation Technique has been left to collect dust in the warehouse.
He recently discovered that there are some elements in the Heart Hand that seem very similar to the descriptions in the "Heart Sword Scripture."
The "Heart Sword Scripture" emphasizes that the heart is the sword, and it uses the heart to wield the sword.
