"Christina, every card maker should believe in their feelings, don't lose confidence because of a few failures, adding shading to a card is a very interesting idea, this is something that has never been done before, we don't have any reference, failure is inevitable. Another somewhat old female voice said that she should be Professor Nangong.

"But we've failed two thousand three hundred times!" Christina was still a little frustrated.

"This shows that we have eliminated two thousand three hundred wrong directions, and I believe that the dawn is not far ahead!" Professor Nangong comforted his proud protégé.

"Professor, I have a whimsical idea...... "Christina cheered up, returning to the experiment itself.

"Imagination is the wings of a card maker, and any idea is important. Professor Nangong encouraged.

"Professor, I think if cards can really add shading, maybe shading and mystical patterns won't be the same system. Christina said.

"Isn't it the same system?" Professor Nangong was slightly surprised, but Luo Xiaofei's heart moved, thoughtful.

"That's right!" Christina paused for a moment, sorted out her thoughts, and said, "We've been studying shading in the way of depicting secret patterns, but in this way, it's actually no different from carving two secret patterns on the same card. ”

"So you think that shading should be another system that is different from secret patterns?" Professor Nangong was surprised.

"Yes!" Christina's tone was a little frustrated, "but this is tantamount to reinventing a new way of using secret energy, how can we possibly do it!"

"Yes, it's hard to ......" Professor Nangong was silent for a moment and sighed, "But isn't it the most worthwhile job to create a new way of using secret energy?" Maybe we can only make a start and light a small flame in our lives, but even so, this small flame is enough to make us famous in history, are you right, Christina!"

"You're right, Professor!" a bowl of chicken soup struck Christina, who was hot all over her body and reinvigorated herself.

Luo Xiaofei was also enthusiastic, of course, he had long been immune to chicken soup, and what made him excited was the "other system" that the two people upstairs said!

The secret energy is the aura!

So, cards are another way to use Reiki, and in the same way, aren't talismans another way to use secret energy?

If you can really add shading to a card, runes are the best shading!

Luo Xiaofei couldn't wait to find a place to test this idea right away. But as soon as he wanted to start, he stopped again and looked upstairs, and could only see two white figures.

This idea was put forward by the two people upstairs, and if you just use it for your own use, wouldn't it become plagiarism?

Luo Xiaofei can plagiarize the music of another world without any psychological pressure, because it has no effect on the musicians of the earth. But he can't take the things of this world and use them, which violates his code of conduct.

What's more, the two people upstairs are undoubtedly great people who are ready to do pioneering careers, and they are both women, which makes Luo Xiaofei even more stressed.

......

The conversation upstairs continued, but Luo Xiaofei was already entangled.

After a while, he finally figured it out.

Talismans are mature systems, rooted in a great civilization with a history of 5,000 years, and the two upstairs will never be able to create talismans out of thin air in their lifetimes, and it is more likely that even if they spend their entire lives, they still can't add shading to cards.

Then, it is better to help them yourself, as a reward for taking away their ideas.

After making up his mind, Luo Xiaofei summoned the inventory in his mind and took out a brush, a piece of cinnabar, and a piece of yellow sheet paper. He went to the nearby pool to get some water, mixed the cinnabar into paint, and after a little contemplation, picked up the wolf's brush.

He wants to draw a talisman and give it to the two upstairs, and whether or not he can learn anything from this talisman depends on their talent.

"Heavenly Master Talisman" is only an introductory state, and the aura is only a little bit, Luo Xiaofei can only make the lowest level of talismans, he considered it for a while, and decided to draw a condensing talisman, so that the effect of the talisman is more intuitive.

Just behind the experimental building, with the help of the light, Luo Xiaofei dipped his brush in cinnabar and began to move the pen on the yellow table paper......

"Christina, it's still early, let's do another experiment, this time we'll change the ...... Huh?" Professor Nangong finished drinking a cup of coffee and was about to ask his disciples to continue working, when suddenly a hint of surprise appeared on his face, and he turned his head to look in the direction behind the experimental building.

At the same time, Christina also felt something, frowned and looked in the same direction, and said in surprise: "Professor, there is a secret energy fluctuation over there, very close, is someone using a battle card?"

"No!" Professor Nangong shook his head and said, "The amount of secret energy is very small, it is not any kind of battle card, and besides, this kind of fluctuation method is very strange, I have never seen it!"

"It's really peculiar!" Christina said in surprise, "and it's a regular fluctuation, it's not a natural fluctuation of the secret energy, it's someone using the secret energy!"

"Very interesting fluctuations, let's go take a look!" Professor Nangong became excited.

"Good...... Ah, the fluctuations have stopped!" Christina took a step, and suddenly stopped, because the fluctuations had disappeared.

At this moment, I heard a "pop", and something flew up from downstairs and bounced into the laboratory on the windowpane.

Professor Nangong and Christina hurriedly looked downstairs, but they could only see the dark grove outside the lights, and there was no one in the shadows.

"Who is it?" Professor Nangong frowned.

"Look, Professor, this is what was thrown in!" Christina found the thing on the ground and handed it to the teacher.

It was a small stone wrapped in yellow paper.

Professor Nangong carefully opened the yellow paper, only to see a peculiar pattern painted on this crumpled paper. The lines are natural and smooth, rough and subtle, and a sense of ancient mystery comes to the face.

"Professor, what is this, it seems to have a secret breath?" asked Christina, puzzled.

"It's ...... Christina, quick, immediately test this paper comprehensively, I want to know all its data!" Professor Nangong frowned and thought for a while, and his eyes suddenly widened.

"Professor, have you found anything?" Christina hurriedly turned on the various testing instruments and began to prepare for the test.

"Christina, I have a hunch that there may be a breakthrough in our project!" Professor Nangong carefully held the yellow paper, as if holding a rare treasure.

"Because of this paper?" Christina asked.

"Yes, because of this paper!" Professor Nangong nodded heavily.
