After leaving the treasure room, they both walked through the castle.
"Have you been cultivating with that spiritual vein?" Tang Yin asked Zu Xiaolin, and she nodded to him.
"My room is on the other side of the Treasure Hall, that's why I've been able to increase my cultivation so fast. But I must stop now, I can't go up so much like this and the energy must be used to increase the strength of my father's most loyal leaders." She replied with a smile, and Tang Yin then nodded.
"So that man is the Vein Master?" Tang Yin asked doubtfully, and she nodded.
Tang Yin then smiled a little.
'A Master of a Spiritual Vein, who is a normal person... What a surprise to find this kind of thing here.' He thought.
Normally, owners of Spiritual Veins are strong cultivators and become stronger with their spiritual vein, so they can easily dominate an entire kingdom, empire, or any similar organization.
To find a Master of a Vein, who is not a cultivator…
It is a big surprise.
If a cultivator encounters such an occurrence, he will most likely assassinate that master to become the master himself. For, if he is attached to the spiritual vein, his life expectancy is greatly increased, and his cultivation would be skyrocketed.
That's what surprised Tang Yin.
'It seems that this imperial family is quite special in many ways. They have a lot of sense of morality and loyalty.'' Tang Yin thought with a smile.
At that moment, they both arrived outside the palace.
"Young Master Tang, must you leave so quickly? You've been around for such a short time; I haven't even attended to you properly..." Zu Xiaolin said with some pity in her voice.
Tang Yin simply nodded.
"There are things I have to do, but you can go visit me these days while I'm here. I already gave you the address. Also, I'll leave you some things with Feifei, you can ask her when you see her." Tang Yin said.
"For now, I will say goodbye, Miss Zu. I look forward to your visit over there, I won't be in the city for long." Tang Yin said as he went ahead to walk, and Zu Xiaolin nodded to him.
Although she wasn't looking forward to him leaving.
"It's alright, Young Master Tang. I'll come to visit you later or tomorrow, I'm sorry for giving you such a small gift for all you did for me." She said with a nice smile on her face, but somewhat lonely.
As the princess of this place, she usually has few friends or people she can hang out or chat with. She has siblings, but they are all busy or just distant from her because her father chose her over her brothers to inherit the throne, even though they are older.
That's why she feels lonely occasionally, but she can't do anything about it.
Tang Yin noticed this but still left.
He has no time to keep other people company at the moment.
After leaving the Imperial Castle, he walked around the city looking at different things from place to place. He passed by the alchemist association and other places selling items good for cultivation and bought a great amount.
He had bought different kinds of pills in great quantities, as well as having prepared a lot of material for writing cultivation techniques and other necessary preparations he needed to make before leaving.
In addition to that, he was looking for information in different places.
But his search for information was fruitless, so he ended up returning to the house where he was staying.
Here were Huang Feifei and Li Mei waiting for him.
When Huang Feifei saw him, she smiled and ran to him.
"Tang Yin, where have you been? We came early to look for you, but you weren't around." She asked as she hugged him.
Tang Yin smiled at her and petted her a little.
"I was at the Imperial Castle. Miss Zu gave me some things and I was talking to her a bit. I also bought several things, let's go inside, I want to show you some things." Tang Yin said and looked at Li Mei.
"Miss Li, come with us." He said.
They both nodded not knowing what they were going to do, but followed him.
Inside the house, Tang Yin first took out a great number of pills, spiritual herbs, and other materials needed for cultivation.
He couldn't find good treasures at a low price, but, even so, he had still bought enough stuff.
"I think both of you are suitable to learn about Spiritual Matrices, so I will teach you how to make an amazing, but easy-to-make matrix so that you can increase your cultivation faster." Tang Yin said and then took out some brushes with white paint.
He bit his finger a little and poured some blood into the white paint.
"You girls watch from the side. It will only be enough once for you to learn how to make this array, but it will serve you for a lifetime." Tang Yin said with a smile and soon began to mix the white paint with the drop of blood.
The drop of blood failed to change the color of the white paint, as the difference in quantities was too much.
One was a pot of paint of more than five liters, and the other was a small drop of blood.
But Tang Yin quickly grabbed the brush and a large blank sheet of paper and began to draw a small square spiritual matrix, but rotated at 45 degrees.
The square array had four inward-facing lanes, and they were beautifully painted. Clearly, Tang Yin was an expert at this.
Once he finished the small square matrix, he started drawing a round matrix in the bottom corner with three inward-facing lanes. Then he did the same on the right corner, making exactly the same matrix, and then on the top corner...
He did it as if he was drawing rotating counterclockwise.
So, he ended up with a round matrix with the same design and intensity as the other three in the last corner, the one on the left.
After he had done that, Tang Yin made a bigger round matrix that wrapped all these matrices.
Then he smiled and poured some of the previously whipped paint on it until it was completely soaked.
Following that, Tang Yin did the same with four other papers.
Exactly the same.
And then he stood up and put four iron stakes in 4 different corners. If you looked from above, could see that, between the little stakes, they made a perfect square.
After that, Tang Yin drove the stakes into the ground while pressing one corner of the paper with the dies against the ground.
Then he smiled, went back to the center of this place, where the painting was on top of the last paper with matrix, and poured another drop of his blood on the painting.
As soon as he did this, a glowing yellow light lit up on the paper below the paint with the drop of blood.
Soon that yellow light rooted itself to the spiritual matrix that Tang Yin had drawn there and made it fully illuminated with a yellow glow.
This triggered the other four corners to do exactly the same thing.
The four papers containing a spiritual array soon glowed in a deep yellow color, just like the first one.
Following that, the four papers that had the spiritual matrix that were in the corners wrapped themselves around the iron stakes, and so...
It started to work.
The yellow color would not fade for quite a while after that.
The two girls were amazed by this. They never thought that a spiritual matrix, one of the things that are supposed to be the hardest to make, could be completed with things as simple as that, but they still didn't understand what they were for.
What was their function? They thought doubtfully.
But they didn't have to think long.
Soon, they both noticed something and stood in shock.
