"Grandma..." Hao Ren tried to speak, but Qingfeng Hermit ignored him and placed her hand on his forehead.
Hao Ren felt a complete technique entering his mind from his forehead, and he could see each character. Just like when he immersed his spiritual senses into the jade slip which contained the Mystic Water Sword Techniques, he couldn't see it directly but could feel it.
In fact, the profound and secret techniques wouldn't be recorded. Instead, they were passed down from the masters to the disciples through spiritual senses.
If the disciples had low realms and couldn't be taught this way, the ancient cultivators would print the techniques into special jade slips and then leave the opening method to the disciples. When the latter had reached certain realms, they would use the methods to open the jade slips. Of course, the masters were usually not with the disciples or had passed away by this time.
