After leaving the battle hall, Duan Yi went straight to the academy's spirit card store to buy a green-quality environmental spirit card to upgrade the gravity magnetic field.

Although it is not clear what attributes will become after upgrading, it must be very strong. This is Duan Yi's ace spirit card and must be upgraded as soon as possible.

"Boss, I would like to ask, is there any cheapest green quality environmental spirit card?"

After Duan Yi entered the store, he walked to the counter and asked the boss.

"Oh? The cheapest green quality environmental spirit card?"

The boss was slightly stunned when he heard this. After all, ordinary people came to consult the environmental spirit card, and usually asked which one was the most useful and powerful. Few people would come to ask which one was the cheapest, which made the boss a little unresponsive for a while.

"Yes, I want the cheapest one." Duan Yi nodded slightly.

"There are, but there are no good products at all, so the classmate should buy the one that is valuable." The boss said with a smile.

"No need, I just study it, so I can just pick one of the cheapest ones."

The boss didn't deliberately want Duan Yi to buy expensive things, but he was indeed reminding himself, but Duan Yi really didn't need it, so he refused decisively.

"Oh, then okay, this store will not return the goods."

Seeing this, the boss sighed slightly, and then took out some green quality environmental spirit cards from the cabinet next to him.

"These green quality environmental spirit cards are all at the same price, with a score of 500 points in college, and the effects are very mediocre. Students can check the effects on their own."

The boss is too lazy to introduce the effect to Duan Yi. Anyway, these green-quality environmental spirit cards are indeed not very good.

"500 points, no problem, I want this one."

Although the attribute panels of these environmental spirit cards appeared in Duan Yi's mind, they were indeed very garbage. Duan Yi was too lazy to read them, so he picked one at random and paid 500 points.

Anyway, they are just used to upgrade the gravity magnetic field, so no matter what effect it is.

As for 500 points of college points, this price is indeed not expensive, much more cost-effective than outside.

After learning about Yanhuang Academy during this period, Duan Yi also understood what the approximate ratio of converting the college points into Blue Star Coins.

Almost ten thousand blue star coins are equal to 1 academy point, which means that 500 points of this environmental spirit card is equivalent to 5 million. However, if you are 5 million outside, you will definitely not be able to buy a green quality environmental spirit card, even the most trashy ones.

This is only in the academy where there is such a cheap price. Of course, the main reason is that these green quality spirit cards are not effective and cannot be sold for a long time, so they can only be sold at a low price.

If it is a green quality environmental spiritual card with better effect, then 500 points will definitely be too small.

"Okay, I received the points, welcome next time."

The boss was very happy to have these environmental spirit cards that no one wanted at the bottom of the box.

"Yeah, bye."

Duan Yi waved at him and left here.

Afterwards, after returning to the villa area and having a hurry to have a meal, Duan Yi returned to his own single-family villa.

......

"Come on, we're finally going to start upgrading."

Duan Yi sat excitedly on the sofa in the training room, took out the environmental spirit card of the gravity magnetic field, and also took out the two green quality environmental spirit cards used as upgrade materials.

One of these was sealed by Duan Yi in the secret realm of Huifu Group. Now, it is really thrilling and almost died in the hands of the Earth Demon Silver Dragon.

Then, Duan Yi placed the environmental spirit card of the gravity magnetic field in the center of the table, and the other two environmental spirit cards were placed next to it.

After all, it was the first time that the gravity magnetic field was upgraded, and Duan Yi didn't know how to operate it for a while, so he could only try it first.

At this moment, the gravity magnetic field in the middle immediately emitted a blue light and slowly floated up. Then, two green-quality environmental spiritual cards in the spiritual position also floated up together.

Slowly, the two environmental spiritual cards turned into two blue lights and were absorbed by the gravity magnetic field. The gravity magnetic field environmental spiritual cards immediately emitted a dazzling blue light.

After the blue light dissipated, a brand new attribute panel appeared in Duan Yi's mind.

Spirit Card Variety: Environmental Spirit Card

Spirit Card Level: Blue

Seal environment: gravity magnetic field

Environmental properties: Gravity system

Environment introduction: A special field formed by the rules of heaven and earth is sealed with powerful sealing techniques. Within the range of the spiritual card in this environment, the spiritual card master can use two skills, gravity suppression and gravity release.

(Note: This environmental spiritual card requires a spiritual card master to reach the silver level or above before it can be used; and this environmental spiritual card has growth potential, and can evolve by absorbing other environmental spiritual cards; if it evolves to purple quality, it is necessary to absorb two blue quality environmental spiritual cards.)

At the same time, the system's voice echoed in Duan Yi's mind at the same time.

"Reminder, the limit of this gravity magnetic field can only suppress spiritual card masters below two stars of gold, as well as purple-quality beasts with combat power below 3500. No ferocious beast can suppress it."

After hearing the system's voice, Duan Yi nodded slightly.

"It seems that the effect has been weakened. All the strange beasts with blue quality were suppressed. Now they can only suppress purple quality beasts with combat power below 3,500."

"But it is acceptable to think about it carefully. As for those powerful purple-quality ferocious beasts, it is normal that they cannot be suppressed."

"And the suppression of the spirit card master has also been weakened. It was before, but it was below the three stars in silver. After upgrading, it did not become below the three stars in gold, but it became below the two stars in gold."

"But although they have been weakened, the effect is still very domineering, and he is still one of Duan Yi's strongest stoppers."

After upgrading, the gravity magnetic field environment spirit card flew back to Duan Yi. Although the effect was upgraded, the appearance still did not change at all, and it was even a bit ordinary.

After Duan Yi observed it for a while, he stored it in the sea of ​​soul for warmth.

Then, before preparing to start practicing, a daily lottery was held.

“Start the lottery…”

"Congratulations to the host for drawing, green quality environmental spirit card, magma surface."

“…”

"I'll go! I wouldn't have bought it for 500 points if I had known it. Isn't this a cheating man?"

Looking at the green quality environmental spirit card that appeared in his hand, Duan Yi felt like he was cheated by the system for the first time. He felt very distressed that he had spent 500 points just now.

"What's the point of using me to want you! It seems that I'm going to find an opportunity to sell you and get back your blood."

Duan Yi sighed slightly, then received the magma surface environment spirit card into the storage ring, and then began the practice of Xuantian Jue.
Chapter completed!
