I traveled through hundreds of worlds at once

The forbidden knowledge in the famous magic books such as "The Book of Solomon's Small Key", "The Book of the Dead", "The Book of Creation", "The Book of Lamentation", "The Book of Laws" and so on, which are recorded deep in Index's brain, flowed into Yihui's mind along Yihui's microcosm.

"Hiss, this feeling is really sour!" Yihui endured the crazy influx of forbidden knowledge that polluted people's souls in his mind, his eyebrows kept beating, and his temples were a little swollen.

The magic books in Index's mind are the accumulation of British Puritanism for countless years. The knowledge in each magic book is very important.
