After leaving the battle hall, Duan Yi went straight to the academy's spirit card store to buy a green-quality environmental spirit card, which could be used to upgrade the gravity magnetic field.
Although I don't know what attributes it will become after upgrading, it must be very strong. This is Duan Yi's ace spirit card, and it must be upgraded as soon as possible.
"Boss, I would like to ask, is there the 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 startled when he heard this. After all, when ordinary people come to inquire about environmental spirit cards, they usually ask about which one is the easiest to use and the most powerful. Very few people come to ask which one is the cheapest, which makes the boss a little unresponsive for a while.
"Yes, I want the cheapest one." Duan Yi nodded slightly.
"Yes, there are, but they are cheap but not good, so students should buy the ones that are valuable." The boss said with a smile.
"No, I'm just doing some research, so I just pick the cheapest one."
The boss didn't mean to make Duan Yi buy something expensive by saying this. He was really trying to remind himself, but Duan Yi really didn't need it, so he decisively refused.
"Hey, okay then, our store does not accept returns."
Seeing this, the boss sighed slightly, and then took out some green-quality environmental spirit cards from the cabinet on the side.
"These green quality environmental cards are all priced at the same price, which is 500 college points. The effects are very mediocre. Students can check the effects by themselves."
The boss didn't bother to introduce the effects to Duan Yi. Anyway, these green-quality environmental cards were really not that good.
"500 points, no problem, I want this one."
Although the attribute panels of these environment spirit cards appeared in Duan Yi's mind, they were indeed rubbish. Duan Yi didn't bother to look at them, so he picked one at random and paid 500 points.
Anyway, it's just used to upgrade the gravitational field, and it doesn't matter what the effect is.
As for the 500 college points, the price is indeed not expensive, much more cost-effective than outside.
During this period of time at Yanhuang Academy, Duan Yi also understood the approximate ratio of academy points to blue star coins.
Almost 10,000 blue star coins are equivalent to 1 academy point. In other words, 500 points for this environmental spirit card is equivalent to 5 million, and 5 million cannot buy a green quality environmental spirit card outside. , not even the most rubbish ones.
This is such a cheap price only in the academy. Of course, the main reason is because these green quality spirit cards are not very effective and cannot be sold for a long time, so they can only be sold at low prices.
If it is a green quality environmental spirit card with better effects, then 500 points is definitely too little.
"Okay, I received the points. Welcome to visit next time."
The boss was very happy to finally sell one of these environmental spirit cards that no one wanted at the bottom of the box.
"OK Bye Bye."
Duan Yi waved at him and left.
Later, after returning to the villa area and having a quick meal, Duan Yi returned to his small single-family villa.
...
"Come on, it's finally time to upgrade."
Duan Yi sat excitedly on the sofa in the training room and took out the gravitational magnetic field environmental spirit card. At the same time, he also took out two green quality environmental spirit cards used as upgrade materials.
One of these was one that Duan Yi had sealed in the secret realm of the Huifu Group. Now that he thinks about it, it was really thrilling, as he almost died in the hands of that evil silver dragon.
Then, Duan Yi placed the gravitational magnetic field environmental spirit card 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 to upgrade the gravity magnetic field. Duan Yi didn't know how to operate it for a while, so he could only try it first.
At this moment, the gravitational magnetic field in the middle immediately emitted blue light and slowly floated. Then, the two green-quality environmental spirit cards in the spirit position also floated together.
Slowly, the two environmental spirit cards turned into two rays of blue light and were absorbed by the gravitational magnetic field. The gravitational magnetic field environmental spirit cards immediately emitted a dazzling blue light.
After the blue light dissipated, a brand new attribute panel appeared in Duan Yi's mind.
Type of Spirit Card: Environmental Spirit Card
Spirit Card Level: Blue
Seal environment: gravitational magnetic field
Environmental attributes: Gravity system
Environment introduction: A special place formed by the rules of heaven and earth is sealed with a powerful sealing technique. Within the scope of this environmental spirit card, the spirit card master can perform two skills, gravity suppression and gravity release.
(Note: This environment spirit card requires the spirit card master to reach Silver level or above before it can be used; and this environment spirit card has growth ability, and can be evolved by absorbing other environment spirit cards; to evolve to purple quality, two blue cards need to be absorbed. Color-quality environmental spirit card.)
At the same time, the system's voice also echoed in Duan Yi's mind.
"Reminder, the limit of this gravitational magnetic field can only suppress spirit card masters with a golden level below two stars, and purple quality beasts with a combat power of less than 3500. No ferocious beasts can suppress it."
Duan Yi nodded slightly after hearing the sound of the system.
"It seems that the effect has been weakened. Previously, all blue-quality alien beasts could be suppressed. Now, it can only suppress purple-quality alien beasts with a combat power of less than 3,500."
"But if you think about it carefully, it's acceptable. As for those powerful purple beasts, it's normal that they can't be suppressed."
"Furthermore, the Suppressing Spirit Card Master has also been weakened. It used to be below Silver Three Stars. After the upgrade, it did not become below Gold Three Stars, but below Gold Two Stars."
"However, even though it has been weakened, the effect is still very overbearing, and it is still one of Duan Yi's strongest back-ups."
After the upgrade, the gravitational magnetic field environment spirit card flew back to Duan Yi's hands. Although the effect was upgraded, the appearance still did not change at all, and was even a bit ordinary.
After Duan Yi observed it for a while, he stored it in the soul sea to warm it up.
Then, before getting ready to start training, there was a daily draw.
"The lottery begins..."
"Congratulations to the host for winning the green quality environment card, magma surface."
"..."
"I'll go! If I had known better, I wouldn't have spent 500 points to buy it. Isn't this a trick on me?"
Looking at the green quality environmental spirit card that appeared in his hand, Duan Yi felt for the first time that he had been cheated by the system. He was very distressed that he had just spent 500 points in vain.
"What do I need you for? It seems that I am looking for an opportunity to sell you to get some blood back."
Duan Yi sighed slightly, received the magma surface environment spirit card into the storage ring, and then started practicing Xuantian Jue.
