Zhang Yan's approval excited Meng Yao and Meng Hongwen.

He turned to the old man hesitantly, "But these advanced materials are too expensive for me to afford. Could you please give me a discount? Otherwise you can't see me depicting the Vibration Pattern."

Meng Hongwen saw through Zhang Yan's idea that Zhang Yan begrudged spending so many spiritual stones. He agreed to reward Zhang Yan's generosity of allowing him and his granddaughter to watch Zhang Yan depicting, "I knew it's not that easy. As the president of the Spirit Tattooists Unit in Fengdu City, I can freely offer you the materials you need. But my request is that you must be success, or you should still pay the money."

"Okay, I won't fail." Zhang Yan responded with a smile.

He was also excited to gain free materials. After all, his expenses on spirit tattooing materials was much more than his income of selling spiritual magic figures. What's more, the high-level materials he needed this time were all very expensive, especially the most important onestar stone, the price of which had reached a thousand upper spiritual stones.

Eyes rolling, he began to write down the materials he needed this time and some more he would use for another high-level spiritual pattern.

When Meng Yao got the list, she frowned and asked, "Why so many kinds of materials are listed? Much more than what you just said!"

Zhang Yan scratched his head awkwardly and smiled, "Come on, please. You are such a big family and won't begrudge sending me these materials, will you? "

Meng Hongwen said with a smile: "You, such a slyboot! You can take these materials for free, but you have to tell me about their use."

Zhang Yan nodded with agreement, "Well, they are used for another spiritual pattern."

After that, Meng Hongwen hinted Meng Yao to prepare the materials.

A short while later, she came back with all the materials. In front of them three, Zhang Yan put the materials he didn't need this time in his storage ring smilingly. Then he purified the materials needed for the Vibration Pattern, mixed them together into liquid, ground the star stone into powder and added it to the liquid. It could maintain spiritual patterns' effect forever, so it was valuable.

He was smooth and slow in the process of making spirit tattooing liquid, and careful in the use, even the orders, of each kind of material, without any small mistakes. Meng Yao and Meng Hongwen were observing and doing records carefully on the side, for fear of missing important parts.

However, Yan Luo was standing expressionlessly, because of no interest in spirit tattooing skills. But when he saw Meng Hongwen and Meng Yao studying attentively from Zhang Yan, the latter's status in his heart improved a lot. He used to regard Zhang Yan as a like-minded friend, but now it seemed that Zhang Yan was not just a normal non-schooled warrior but a talented spirit tattooing master.

Being friend with such kind of person was happy for Yan Luo.

Getting done with the spirit tattooing liquid, Zhang Yan placed his stone sword on the stone table, took out his spirit tattooing pen, concentrated all his soul energy and spiritual energy on it. At this moment, he could only saw the stone sword and the pen, like a part of his arm, in his hand, as if everything else disappeared.

"The state of integrating with the nature!"

Meng Hongwen shouted in his heart shockingly, "This state could emerge not only in the practice of martial arts, but also in the spiritual patterns making, which was the dream of all spirit tattooists, because in such state, our potential could be fully activated."

How could he expect that Zhang Yan reached the state at the moment of taking the pen, which he had never achieved. If not for disturbing Zhang Yan, he might have screamed out loud.

Meng Yao was looking at Zhang Yan startlingly, as if watching her idol.

Zhang Yan quickly swung the pen without a trace of pause. The Vibration Pattern was completed in less than a moment, which surprised Zhang Yan himself as well. The most amazing was that he entered the state of integrating with the nature for the first time and during this time, his soul was not consumed, but increased.
