Chen Du has been able to walk quite freely in the simple water world, and he has gradually adapted to this strange environment. Especially the water pressure, the first time he entered, he felt like he was almost bursting with the terrifying water pressure.

In such a situation, it is not easy to reduce the breathing rate to once per minute. But Chen Du did it. The advantage of using this deep breathing is that the heart rate can be greatly reduced, and it is easier to achieve deep meditation.

Chen Du can now enter the deep meditation relatively quickly, and it only takes about two minutes each time.

Fortunately, this is just a "simple water world", if it is really underwater, then let alone breathing, I can't see if I can't kill you!

He didn't know how strong his perception really was without testing. He just knew that now he felt that he could basically support him to make card shadows for a whole day without exhaustion.

However, he still couldn't spread his perception to a range of five meters around him. The extreme he can do is 4.5 meters, and the difference is 0.5 meters, and he can't radiate his perception there. It was as if as long as his perception stretched a little further, he would lose contact with him.

This shouldn't be a matter of perception intensity, Chen Du secretly speculated, but the mysterious card didn't seem to record this point, so he had to explore it himself.

Fortunately, there is nothing in the hurry, with his current perception, it is enough for him to do a lot of things. For example, learning some other cards, such as airflow cards, heating cards, fog cards, etc., which he would never have dared to think of before.

The classification of cards, whether in the Heavenly Cultivation Federation, or in the Baiyuan Mansion and the Mohadi Domain, is a headache. There are a lot of cards, and it's hard to divide them into one category.

Chen's first learning was the heating card, which is one of the most commonly used cards. The heat cooker is a must-have item in every family, and its core is a simplified heating card. And for those Cassius who often go to the wild, the heating card is also one of the must-have cards, which allows them to eat cooked food in any condition without having to look for dead branches to start a fire. In addition, it is often used for heating in the cold winter.

The esoteric and difficult terms used to make cards are now clear at a glance. Chen Du got started very quickly, and in just two days, he had already made his first one-star heating card. On the third day, the one-star heating card he made was already relatively perfect, and the use rate of energy was also higher. So Chen Du simply dismantled the heat pot at home and replaced it with the one-star heating card he made. After trying it, it really works well, and even Lei Zi is amazed.

This also made Chen Du immediately obsessed with the transformation of items in the home. Freezer card for fresh food cabinet, lighting card...... Even the one-star airflow card that Chen Dui originally thought was useless was fully excavated. The airflow generated by the one-star airflow card is not strong, but it is perfect for blowing wind and cooling.

But wherever the card is used at home, Chen Du will find a book on this subject and do it himself. Since the thugs had more money, Chen Du had bought a large number of books, and now his room was full of materials and books at most. The basic knowledge learned from the mystery card, especially its exposition of some principles, benefited Chen Duan a lot. These days, he is not exposed to magic cards, but in principle, they are not fundamentally different.

It's all thanks to that mysterious card.

There was a knock on the door.

"Is Mr. Chen Du at home? This is your letter, please sign for it. ”

Chen Du was stunned, this was the first time he had received something other than a bill.

When I opened the envelope, it was a blue-edged white card, about half the size of a palm, with an ivory-white clear village quality, and it felt excellent to the touch.

Low-level Phantom Club membership card.

There are a few fonts with a bit of antiquity on the surface of the card, and it took Chen Duan a lot of effort to recognize them. And in the upper right corner of the card, there is a faintly shiny number with the number "zero" on it. And in the lower left corner, a string of codes is inscribed.

"Don't look at it, it's not a high-end product." After Lei Zi, who poked his head out, saw it, he couldn't help but say: "This membership card is not valuable, what is valuable is the contribution, your contribution is only zero now, and no one will pick it up if you throw it on the street." ”

"Contribution? What is it used for? Chen Du couldn't help asking, but he was a little ashamed in his heart, he just thought that this card was quite valuable.

Lei Zi stretched lazily before saying, "This is the incentive system adopted by the club. Didn't you notice that the barrier to entry for this club is low? In order to screen out those who have real skills and are concerned about the affairs of the club, there is a contribution degree. Seeing that Chen Du was still looking at him, Lei Zi shrugged his shoulders and said irresponsibly: "Don't look at me, I know so much." Won't you just go over tomorrow and have a look? Where is the use of asking me this layman? ”

Low-level Magic Card Club.

It was the first time Chen Du had come here, and he couldn't help but take a closer look at the building. To have a high-rise building in the heart of the Eastern Business Acropolis is enough to show the strength of this club. What caught Chen's attention the most was the exquisite illusion card images floating on the exterior wall of the building, which were constantly changing, suddenly freezing and snowy in winter, and suddenly full of verdant eyes......

It's dizzying to watch, and with Chen Duan's eyes, I can't help but be secretly amazed. When it comes to realism, even the last time I saw the advertisement at the Shuanghuan card store, it can't compare with these illusions that change from time to time. Of course, this was not the first thought that crossed Chen's mind. His first thought was, how much should a magic card that could release such a beautiful illusion be worth?

This is indeed a place where the dragon and the crouching tiger are hidden, he doesn't know who makes these magic cards, but the person who can make such a realistic illusion is really a powerful person! Chen Du thought to himself that with his current level, it would be difficult to do it.

Suppressing the curiosity in his heart, Chen Du stepped into the building.

As soon as I walked into the building, the surrounding scenery suddenly changed.

In front of me, in the darkness, I saw the stars slowly making incomprehensible movements, as if suddenly, I stepped into the starry sky of the universe. In it, there was an endless void in all directions, countless stars and a sea of stars, and the sense of landing under his feet became so unreal at this time. All of this gives people an incomparably strong shock! Where had Chen Duan seen such a scene, and his eyes suddenly showed incomparable surprise.

"Welcome to the low-level Magic Card Club." A soft female voice came from behind Chen Dui.

Chen Du suddenly recovered from his shock and turned to see a short-haired woman in professional attire standing behind him.

"This is the Stellar Evolution Phantom Card, which is said to be the work of Master Chemosikh, who has a deep knowledge of the study of stars. Later, this set of magic cards ended up in the hands of the chairman, and the chairman decided to put it here, and everyone was startled when they first entered. She covered her mouth and chuckled, full of charm.
