บท 78: 78. Infiltration

'Ah, man! Why is language so damn hard?' Kai cursed their creativity.

Kai can easily sense the change in frequency, but he wasn't able to understand it.

'Now, I only have to use this method.' Kai used his Will Power to capture a Tier 1 and spirit.

He forced his Will Power to control it. The sand spirit wasn't able to resist and soon became his puppet.

"Teach me about your communication method." Kai commanded the sand spirit.

He knew that the Sand Spirit tribe must have some sort of method to teach their newborn, so he decided to use that to learn their language.

The sand spirit taught Kai everything about their language. He memorized everything and let the sand spirit go.

'Their language wasn't hard; I only need to practice a little bit and can learn it in a day.'
