There are four levels of energy cards, which are white, silver, gold, and black.

There are four levels of energy liquid, which are elementary, intermediate, advanced, and superb.

The white card stores the primary energy liquid, the silver card stores the primary and intermediate energy liquid, and the gold card stores the primary, intermediate, and advanced energy liquids.

The black card can store any kind of energy liquid, no matter how special the energy liquid, all of them can be stored.

Energy liquid is required to upgrade the energy card, 500,000 primary energy liquid is required to upgrade the white card to the silver card, 10 million intermediate energy liquid is required to upgrade the silver card to the gold card, and 100 million advanced energy liquid is required to upgrade the gold card to the black card.

There is an upper limit on the energy card that can store energy liquid, 100,000 for the white card, 5 million for the silver card, 100 million for the gold card, and no limit for the black card.

In exceptional cases, the energy card has a temporary storage limit.

It does not consume energy in one day, and after one day, it will be added from one point to the top, doubling in one day.

When she got the energy card, Dai Chun'er had already told herself about the energy card.

Yue Ruxue bit her lip and thought for a while and said, "I'll give you 500,000 primary energy liquid upgrade energy cards first, and then give you 800,000 intermediate energy liquids, is that okay?"

Qin Bingyan blinked: "Okay, that's it." ”

I don't know the exchange ratio of energy liquid, and I don't think the moon is like snow and it won't trick people.

The most important thing is that cultivating with low-level energy liquid is too slow, and there is a chance to get an intermediate energy liquid, Qin Bingyan doesn't want to refuse.

Yue Wenyao pulled Yue Ruxue: "Baby, if the baby wants it, I'll buy it for you, I'll buy it for you." ”

Yue Ruxue glared: "Let go, I have my own energy liquid, so I don't need you to meddle with things." ”

The first time he traded low-level energy liquid, Qin Bingyan used energy liquid to upgrade energy cards.

Looking at the silver energy card, Qin Bingyan muttered in his heart: "It's so convenient." ”

With energy liquid, upgrading is a matter of moments.

After obtaining the intermediate energy liquid, Qin Bingyan handed over the shrinking trojan.

Yue Ruxue is easy to talk to, she can't let her be blind, Qin Bingyan's memory quickly went over: "Dong Yuzhen has a book on this topic, you can go over and read it and learn how to operate." ”

Yue Ruxue looked puzzled: "Yes, how come I don't know." ”

She has studied with Dong Yuzhen for a few years, how did she not know that Dong Yuzhen has books on this subject.

Qin Bingyan nodded: "Yes, I saw that there were books on the shelves related to mechanical arts. ”

Yue Ruxue stared at Qin Bingyan, this guy was too hateful, and he deceived the energy liquid that he had accumulated to upgrade the energy card.

"Hmph, I'll go over and take a look, if you lie to me, I, I'll smash your shop. ”

Qin Bingyan shouted: "Hey, wait, don't go to school at night, if you go, bring some people, don't be alone." ”

Looking at the guy who ran away, I don't know if I heard it.

Qin Bingyan looked at the energy card, the intermediate energy liquid was much better than the primary energy liquid.

Putting away the energy card, Qin Bingyan looked at the guy who hadn't left and said, "Hey, let's go, I'm going to close the business." ”

Hei Tianrui stared at Qin Bingyan and said, "Did you use the wrong word?" ”

Seeing that Qin Bingyan ignored people, Hei Tianrui asked, "Why did Yue Wenyao make Yue Ruxue angry again?"

Qin Bingyan rolled his eyes: "This is not clear, Yue Ruxue wants a Trojan horse, Yue Wenyao muttered while muttering, looking good for Yue Ruxue, and never considered Yue Ruxue's mood." ”

Hei Tianrui glanced up: "How is it good for the child?

Qin Bingyan asked Cangtian speechlessly: "It's good for the child, you need to consider the child's mood, guide her correctly, tell her everything, instead of hiding it, I feel that this can't be said, and that can't be asked." ”
