"This is a talisman." Night emperor flipped his hand and produced two triangular crystal like rocks with complex engravings on them. This was somewhat similar to the jadeite of earth.
"Once you send your spirit imprint in, you'll become its master." Night emperor said. "Only with this…can you enter the tower. Otherwise, you cant even get in."
"These engravings are infused with the space laws and water laws. Wow, how mysterious." Piercing Tiger emperor couldn't help but say as he received the talismans and examined them. Luo Feng sent a thread of spirit energy in and immediately placed his spirit imprint, it fused right into his skin.
The spirit imprint was an imprint of the soul, a mark of life.
Piercing Tiger kept his too.
"Alright, let's go." Night emperor said.
Xiu!
The three warriors from the human camp instantly vanished from the cave and appeared deep underground over a trillion km away.
...
Deep underground.
