After thinking about it, Lin Cheng took out a bunch of different items from the storage capsule and tried them one by one, and after half an hour of experimentation, he finally understood what the price of this exchange system was based on.

To put it simply, the price of this exchange system is basically the same as the price in the end times at this stage, that is, the exchange system will recycle items that most of the survivors feel precious at this stage, and at a very low price.

For example, the first item he just recycled, Tianye cigarettes, he later tried it with other brands of cigarettes, and most of the quotations given by the system only hovered between ten and twenty energy values, and he never gave such a high price to Tianye cigarettes, but the quotation of cigarettes was still high compared to most items.

This is because cigarettes belong to the category of luxury goods in the last days, even if the cigarettes are of inferior quality, due to the high demand and can no longer be produced, the quotation given by the system will be high, and the price of Tianye cigarettes as a high-end series is naturally higher.

The second time as an experiment of charcoal-grilled venison, although Lin Cheng personally thinks it tastes good, but it is only food at best, maybe half a year ago food was still precious to the survivors, but after a year of crawling, the vast majority of the survivors at this stage have solved the problem of food, coupled with the system's high standards of food production technology, that piece of charcoal-grilled oven meat naturally cannot give a higher price.

As for some other items, such as batteries, tissues, drinks and other daily necessities, the quotations given by the system are also different, but almost all of them are higher than the price of food, but even if it is high, it is only a drop in the bucket for Lin Cheng, a large energy demander.

He roughly calculated that even if all his current reserves were converted into energy points, they would only be able to exchange for less than a million points at most, and if these reserves were left for him, Bai Ling, and Coke to slowly consume, they would be enough to support their lives for decades!

Obviously, although the exchange system is open to any item, it is simply impossible to fill the hole of Type B enhancement potions with daily consumables, and even if he has so many daily items, it is impossible to fill this big hole, because it is not cost-effective.

During this period, he also tried to use the exchange system to scan the items exchanged from the capsule system, but when he found that the items exchanged for his 5,000 energy points could only be exchanged for 2,500 energy points, he completely died of this heart.

After tossing and turning like a curious baby for a long time, Lin Cheng, who was finally a little tired of playing, suddenly thought that since daily necessities alone could not meet the terrifying energy value demand of Type B enhancement potions, and this exchange system did not refuse anything, why didn't he go to the street to try those 'big items'?

Just do it, Lin Cheng quickly put on his coat, listened to the movement in the bedroom, and saw that Peter, Bai Ling and Coke were sleeping sweetly at this time, so he left the suite lightly and went downstairs to the street.

Standing on the knee-deep street with snow, Lin Cheng took a deep breath, and the air as low as nearly minus 60 degrees at night penetrated into his body, making his originally sleepy head sober up a lot in an instant.

After touching a cigarette and stuffing it into his mouth, and then lighting it, Lin Cheng wrapped himself in a thick coat and walked towards an abandoned car not far away despite the wind and snow.

He figured it out, since the value of daily necessities is low and at the same time it is an indispensable thing for life, it is too cost-effective to exchange it for energy value, but the abandoned vehicles and public facilities on the street have long lost their use value, if the exchange system is even willing to accept these things, then he can be said to have opened a new and full of 'money' road of bright road!

Walking to the abandoned car, Lin Cheng rubbed his hands and exhaled the system panel, and then entered the exchange interface, letting the blue light shine on the body in front of him, but he heard a sudden electronic prompt sound in his mind: "The volume of the exchange target is too large, please choose the host again!" ”

"Huh?"

Hearing this prompt, Lin Cheng was stunned for a moment, and after reacting, he took a closer look at the panel in front of him, only to find that because he was too close to the vehicle, the exchange panel in front of him was not enough to fully reflect the vehicle.

After discovering this, he tried to take a few steps back, framed the abandoned vehicle into the panel like a photo, and chose to redeem it again, but he heard a prompt sound in his head that was exactly the same as just now!

"What the hell is this...... Does this mean that the volume of the exchange item must be less than or equal to this panel frame? ”

After the exchange failed again, Lin Cheng completely figured out that this exchange system can only exchange those smaller items, and it cannot be exchanged beyond the scope of the exchange box.

But the problem is that this exchange box is not small, but it is by no means big, about four or five cigarettes can fill the entire exchange box, such a volume limit has locked the way to exchange large items, and directly shattered his illusion just now!

A little unrelenting, Lin Cheng directly conjured an ice sword, and slashed towards the abandoned vehicle in front of him, since the exchange system has a volume limit on items, and he doesn't want to waste daily necessities, then he can only start to break this car into pieces of scrap iron that can meet the restrictions of the exchange box!

A few minutes later, the abandoned car that was originally parked on the side of the road had been cut to pieces by Lin Cheng, and pieces of iron the size of a palm were scattered on the snow, Lin Cheng picked up a piece and placed it under the exchange frame, and soon heard an electronic prompt: "Didi - a piece of scrap iron was scanned, due to the extremely low value, the system price is 0.1 energy value!" Does the host perform this exchange? ”

"I'm going - 0.1? Is there a mistake? ”

Hearing the system's offer, Lin Cheng immediately couldn't help but scold angrily, he spent a long time trying to decompose a whole scrapped car into so many pieces, but the system set him an offer equivalent to nothing, according to this offer, even if he exchanged all the fragments on the ground, it was only more than ten energy points.

Although a scrapped car has more than ten energy points is not less, but Kalk City was an empty city before the end of the world, there are not many abandoned vehicles on the street, and most of them are old cars of the last century, even if Lin Cheng splits the cars of the entire city into pieces and replaces them with energy values, it is estimated that tossing for ten days and half a month can also get thousands of energy points, which is not even a drop in the bucket for Lin Cheng, who is now in urgent need of tens of millions of energy values.
