Chen Shi returned home, immediately opened Liu Eunuch's notes, and read carefully. He primarily focused on deciphering runes left by his grandfather, Chen Yindou. In his view, although Eunuch Liu was undoubtedly an outstanding figure of his era, he certainly could not match his grandfather in talismanic knowledge.
However, the runes left by Chen Yindou also seemed like ghost talismans. Chen Shi combined the talismanic knowledge he had learned previously and gradually managed to make some sense of the runes left by his grandfather.
From the understanding of the runes, it seems to be a kind of Thunder Law, which somewhat harmonizes with the Thunderbolt Jade Core Technique that Chen Shi cultívates. However, these runes were extremely arduous for him, as if he were looking at the Immortal Law on the golden books of the True King's Tomb. After researching for a while, he would get dizzy.
