The tattoo was not ordinary tattoo it was a symbol of the demonic cultivation. There was a clan which was actually dedicated to demonic cultivation that was the Shin clan. They were not exactly a family but rather they recruited people who have potential and is also interested. Well, it was indeed true that they were very hard to find and they usually don't appear or make enemy it was certain that if they did. They will go to the extent of killing everyone around them.
Xiaoyan and Jinxiao 2 years ago encountered a man who had a similar pattern. He was thirsty and was starving in the foot path of the mountain. They rescued him and gave him food and water. He stayed there for a while and after few days he disappeared without a trace. While leaving a dragger which needed high cultivation skill to produce. Jinxiao kept it at that time. Xiaoyan and Jinxiao knew where to find. They stared flying towards Shin Mountain of course at was where Xiaoyan tracked her cousin down the previous time before getting kidnapped.
Of course, if her cousin is on the Shin clan then there must be someone who ordered her to do what she did as her cousin knew how miserable she was and what pain she has gone through but it was also true that at some point her cousin humiliated her and treated her like a servant. But that was mainly because she was jealous that Xiaoyan had became the heiress of her family but her cousin is still considered in the second to the line or rather was never in the game. Which made her angry enough to bully her. But that doesn't mean that her cousin ever had the courage to stab someone or kill the spirits.
While Xiaoyan and Jinxiao was flying, Xiaoyan felt something different like someone was watching her. From specially cultivation eye skill. Xiaoyan just let it be at that time. After 2 hours of flying, they landed in front of the major cave of Shin Mountain. Of course, flying is 10 times faster than the carriage. Xiaoyan looked around for a bit. While Jinxiao created a silk white and black mask with his cultivation skills. "It is a demon city for sure." Said Jinxiao. "Demon city?" "Yes, a demon city is basically like a city only but with the demon race. If we see there are many demon cities it is just that not everyone knows their locations and even the Hell itself is a demon city but it is a big and the most major one while the others in the human world are but like a teleportation circle kind of things. Just with the black market and thing. There is also a possibility that the Shin clan is hiding inside one of the demon cities and Shin Mountain itself is a demon city." Xiaoyan nodded. Jinxiao was a demon ming so he knew what is or what are happening in the demon world. They put on their mask and walked into the cave. It was dark and windy, at some point their mask even fell off. After walking few meters. They reached a huge door. It was a wooden old and dusty door. There were actually no guards there. And the door opened easily.
Just as Jinxiao and Xiaoyan thought they entered safely another door appeared and there four guards were there. Xiaoyan sighed and walked towards the other door. Two guards stopped them and asked in the demonic language "Who are you? And do you have an ID pass?" While Xiaoyan didn't understand a thing. Jinxiao stepped forward and took out an ID pass. Which was apparently made out of the gold. After just glancing at the golden pass. They let him in. Jinxiao before going in said "This is my human wife." And dragged her in. The four guards of course suspected a something was wrong but couldn't say anything as a golden ID pass means they are connected to the royal and is very important. After they came inside Xiaoyan asked "What did you talk to them?" "There are something called ID pass which is special permission for you to go to any other demon city and without it going in is practically impossible. But you know I'm was a demon king and I'm a golden pass member. And as for you I just said that you are my human wife. Other-wise It was impossible. Well, there is an exception for wives, sister and lovers." He spoke. "And please act like a wife now." Jinxiao added as he sighed.
Jinxiao never considered Xiaoyan a love interest because first of all Xiaoyan was way younger than him. Like he lived for hundreds of years and Xiaoyan was his who-knows-how-many-greats grandchild. Second of all Jinxiao was already taken by someone. As they walked through the city and the market. They saw all kinds of things. Leg soup, head fried (of a human) and other things. But the most interesting thing that caught Xiaoyan's eye was a particular necklace. It was mostly a silver chain necklace with a dusty sapphire in the middle. But Xiaoyan sensed a special energy which was around the necklace. Jinxiao also sensed something. Like that they bought a necklace in the demon city.
As they walked deeper and deeper, they saw a group of people which was having the identical black robe as Xiaoyan's cousin. So, they were from the Shin clan. Jinxiao and Xiaoyan nodded at each other and started following the people. They were actually pretending to coincidently shop at the same area as them and go around where ever they were going. After a few moments like that a female member among them noticed both of them and started watching them. Of course, both of them get on the alert mode and tried to make distance as more as possible.
