After three days of trekking, Li Yin took Qian Zhen and the three of them back to White Tiger City smoothly, and along the way, Li Yin also figured out what happened to Qian Zhen.

Qian Zhen, as the director in charge of material supply at White Tiger City Pole Technology, immediately realized that this was a business opportunity after hearing that the Flame Mountain Range had changed and the strength of the demonic beast had plummeted.

Not long after, there was going to be a large-scale event in White Tiger City, and he needed to go to the border, so Qian Zhen immediately began to prepare fire-based card materials, preparing to take advantage of the fact that the strength of the demonic beasts in the Flame Mountain Range had dropped significantly, and collect a batch of cheap materials and ship them to other countries to sell at a high price.

So Qian Zhen immediately hired a team familiar with the terrain and environment of the Flame Mountains as a guide in the battle card meeting.

Everything was going smoothly before, but when Xiao Yi and the others hunted six high-level demonic beasts with magic crystals one after another and obtained something extremely rare, the hired adventure group began to go wrong.

On a dark and windy night, all the people brought by Qian Zhen were poisoned, their limbs were weak, and they were slaughtered by the adventure group led by Zhang Feng.

"Thank you for your great help, Pole Science and Technology Building dare not forget. ”

Miao Yin had already received the news as soon as everyone entered the city, and immediately rushed out with people, and personally took Qian Zhen and the other two little ghosts over, Miao Yin after a brief exchange with Qian Zhen, he roughly understood what happened, and after reproaching Qian Zhen for valuing dead things too much, resulting in the death of Xiao San, he respectfully made a big salute to Li Yin, and said without any fraud.

"It's okay, it's just a fair deal, don't take it too seriously, he can promise me that I can choose all the materials on the first and second floors, and I won't charge money." ”

Li Yin couldn't see others treating his luggage the most, so he immediately waved his hand and said with a smile.

"Don't say it's the material, even if you want me to give this store to you, it's right to give it to you, dead things are dead things after all, as long as these people are still there, they can't get anything, it's a pity...... This is the supreme card of the Pole Science and Technology Building, with this card, it is free to pick up materials at any branch of the Pole Science and Technology Building, and the purchase of the card enjoys the reserve price. ”

Miao Yin's face was solemn, and he sighed in a low voice without a slightly sad tone, and handed a card printed with five bronzing characters of "Pole Science and Technology Building" to Li Yin's hand.

Li Yin glanced at Miao Yin with deep meaning, no wonder his business could be so big, not to mention whether he was telling the truth, but just by saying those few words just now, the three Qian Zhen behind him were already fanatical, and they couldn't wait to die for Miao Yin immediately.

"Without further ado, I have one last question, now that you have been delivered safely, can you tell me, what did you get in the Flame Mountains that would cause you to be killed? It stands to reason that the adventure groups registered by the Battle Card will all have a certain amount of defense, and besides, the adventure groups that can be selected by you I don't believe that they will betray their employers for the sake of a little trivial benefit. ”

After Li Yin sighed for a while, he brought up the last doubt that was pressed in his heart.

You must know that the battle card will have a detailed record of each mission, and in order to prevent someone from robbing the house in the name of the mission, every time the employer has an accident, it will be repeatedly and carefully investigated, and the credit limit will be reduced, or even directly dragged into the blacklist.

Under such circumstances, Li Yin couldn't imagine what kind of thing would be able to make the adventure group registered in the battle card club kill the killer.

"Xiao Fan, take out the things. ”

Qian Zhen glanced at Miao Yin, and after obtaining Miao Yin's consent, he waved at the other child behind him.

Xiao Fan, who was about the same size as Xiao Yi, nodded, and then carefully took out a square metal plate that was only the size of a palm and wrapped in animal skins from his arms.

"This is what we found in a ruined ruin, guarded by six mutated beasts, it has only one function known to date, and that is ......"

Qian Zhen just showed the metal plate in front of Li Yin, wrapped it in animal skin, and said softly to Li Yin.

"Move the fine disk!"

Before Qian Zhen's words fell, his soul had already exclaimed in Li Yin's heart.

"What's that?"

Li Yin's eyebrows raised, it was something he had never heard of, but it seemed to be very awesome, so he subconsciously asked.

"Rapid replenishment of mental power without any side effects!"

Qian Zhen looked excited, suppressed his emotions, and whispered in Li Yin's ear the function of the mysterious-looking metal plate.

"Whether it is a card maker or a card master, it takes a certain amount of time to recover after the mental power is exhausted, and there is a lack of continuous combat ability, so someone invented this thing back then. The fine disk has only two functions, one is storage, and the other is rapid replenishment, which can inject spiritual power into it, and mobilize it again when necessary, which is equivalent to several times more spiritual power. ”

Just when Qian Zhen told Li Yin what he had discovered, the soul was more vivid and specific about the function of moving the fine disk.

Li Yin's heart moved instantly, but he didn't say a word, nodded quietly, and led people to the Pole Science and Technology Building to prepare for the purchase of materials.

He is going to move the fine disk, but not now, after all, there are many people on the street now, even if Li Yin gets this thing, he will be targeted by countless people, Li Yin does not dare to be careless, there are already too many secrets on his body.

After purchasing dozens of materials he needed, Li Yin asked Wood to complete the handover of the task, and gave Wood a list, which was full of various necessities of life, and instructed Wood to deal with the tasks of the battle card meeting, and then take the things on the list back to White Cat Town to report safety, and at the same time handed over to Wood two hundred F-level combat skill cards that Li Yin had repaired.

After arranging everything, Li Yin once again devoted himself to card making.

"Everyone's natural caste is different, so when using a certain caste card, it will cause a time when the card is more powerful than the card of the same level. As if it were wood, he used an F-rank fire-based skill card, which is equivalent to the power of a card between F+ and E-. ”

"And you are a dual wind and fire physique, and when you use wind and fire cards, your power will be enhanced. ”

"It is impossible for a person to refine every card to its limit in a limited life, so you need to be focused when making cards. Fire and wind cards are bound to be your focus. ”

"There are two obvious differences between E-level cards and F-level cards, the first is in the structure and number of card patterns, I believe you are already very clear about this. ”

"The second most significant difference is the use of magic. ”

Different from when Li Yin was fighting, in the process of refining cards, the soul no longer mentioned a few words from time to time, but like a mentor, he tirelessly explained the principle to Li Yin on the side.

So that Li Yin can save a lot of time and will not go too far on the crooked road.

Li Yin has a unique talent for drawing, extremely complex three-dimensional card patterns in the hands of others, but in his hands it is extremely simple, with more and more single-series cards refining success, Li Yin is more handy for three-dimensional card patterns, when drawing fire and wind three-dimensional card patterns, there will be almost no mistakes.

However, another focus of the E-level card of the soul theory, the relationship between card patterns and magic, Li Yin has always been in a stage of exploration.

According to the words of the soul, the more card patterns there are, in fact, there are primary and secondary, not the more magic in each card pattern, the better, you need to find the key points, distinguish the primary and secondary between each card pattern, and then distribute the magic power according to the proportion.

Take Li Yin's most refined now is the E-level fire and wind hybrid skill card "Burst Fireball" as an analogy.

"Burst Fireball" has a total of 240 card patterns, and it is a dual-system combat skill card with wind card pattern as the main body and fire card pattern as the auxiliary.

But in fact, on the "Burst Fireball" card, there are only 48 wind-based cards, and the remaining 192 are all fire-based cards.

The fire and wind patterns are closely linked to each other, and the 48 wind patterns are like the longitudinal lines of a spider's web, which plays the role of the backbone, while the large number of fire cards is a short horizontal line on the longitudinal line, although there are many of them, but they are all for the existence of the longitudinal line.

The principle of "Burst Fireball" is also very simple, consisting of 192 fire-based patterns to form a condensed fireball, but in the center of the fireball, it is a more condensed and powerful wind ball.

If the total mana of the "Burst Fireball" is 100, then in terms of mana distribution, the 192 fire-based card pattern soul dances and 48 wind-based card patterns are actually split in half.

This means that the magic contained in a single Wind Pattern is 4 times more than that of a single Fire Pattern!

Only with such a ratio can the "Burst Fireball" burst out with the greatest power at the moment of explosion.

Even so, among the 48 wind system card patterns, there are also priorities, and the specific distribution of magic power, but the soul did not tell Li Yin, but let Li Yin keep trying and groping.

Li Yin also began to try to distribute the magic power of pain and happiness.

For a full month, Li Yin barely had a rough magic power distribution plan for the "Burst Fireball" card, and refined the comprehensive score of the "Burst Fireball", and so far the highest is only D+, and there is still a long way to go before the A proposed by the soul.

Li Yin also finally understood that if he wanted to become a card maker who was proficient in all caste cards, it was almost impossible, after all, this was still an E-level combat skill card.

At the same time, Li Yin also ushered in the most significant competition for the entire White Tiger City.
