"I can't do this anymore! I'm quitting!" Huang Xun gave up after trying the second rune for a while.
Elsa and Gao Fei also gave up, they decided to first see what use others found in remembering these runes before deciding whether to memorize them.
Half an hour later, Li Teng had imprinted four runes in his mind.
After dinner was ready, Li Teng went to eat a few pieces of roasted insect meat and then returned to the training room to continue studying the runes. Over four hours, Li Teng had imprinted all twenty-one runes into his mind.
It was merely a superficial imprint, allowing the thought to summon these runes at any time, but they had not yet been specifically depicted with light points. It felt like only when these runes were crudely sketched over and over again in the mind with light points would they truly become effective.
At this moment, the twenty-one runes appeared in Li Teng's mind in the same order as they were arranged on the parchment.
