A human being inside a portal?

Right now in front of the castle gate, there was a figure standing tall, it was like a burly man.

The man appeared to be in his 50s, wearing no shirt and only wearing pants made of beast skin.

The middle-aged man suddenly opened his eyes and squinted, he suddenly felt something. 

"Human? How could a human get here?" Seeing Lin Tian and Gu Yixian from a distance, a middle-aged man said in confusion.

The middle-aged man didn't look ordinary, he was indeed like a human, well built and two meters tall.

But what made him different was that he had red tattoos on his front, and his eyes were fiery red.

Meanwhile, Lin Tian and Gu Yixian had arrived in front of the castle gate and seeing the middle-aged man standing, it seemed that he was the gatekeeper.

Lin Tian's eyes narrowed, there was a human inside this portal.

"Who are you?" Lin Tian narrowed his eyes and asked suspiciously.
