Even in a more modern and large city with more than 100,000 abandoned vehicles, the time required to decompose these vehicles is huge, not to mention that the energy value provided by more than 100,000 vehicles is only more than 1 million.

Therefore, the road to dismantling items such as abandoned vehicles or large machinery can be regarded as blocked, in fact, if you think about it, if you can exchange any item infinitely, then the limit of energy value is almost meaningless, after all, Lin Cheng is backed by the entire Blue Star, and if he is allowed to exchange it infinitely, I am afraid that the entire Blue Star will be replaced by him.

"Knock ......"

Throwing the iron in his hand on the ground, Lin Cheng sighed deeply, after these few hours of groping for the exchange system, he no longer had the excitement of discovering this new function before, all kinds of restrictions made him feel a little aggrieved, although he understood the intention of the system to do this, but the feeling of looking at the wealth all over the land but not being able to take it for himself still made him very distressed.

Too lazy to do any more experiments, Lin Cheng slowly walked back to the suite, lay down on the sofa to rest for a while, and was ready to go to bed after smoking a cigarette.

But just as he was about to turn off the lights, an idea suddenly flashed through his mind!

"Exchange system...... Valuation...... Volume Limit......"

Talking about a series of operations and restrictions of the exchange system, Lin Cheng's heart suddenly moved, and he quickly sat up from the sofa, forcibly suppressed the excitement and uneasiness in his heart, and slowly took out a piece of fire crystal rough from the storage capsule!

That's right, this is the thought that flashed through his mind just now, since the exchange system has a limit on the volume of the exchange item, and the value of the item within this volume limit is difficult to have super high value, then how much value will the fire crystal with small volume and mysterious effect be judged by the exchange system?

Holding the fire crystal rough stone in his hand, Lin Cheng was a little hesitant in his heart, he had not yet completely grasped the specific role and power of the fire crystal, he didn't know what would happen if he put the fire crystal in the scanning frame of the exchange system, but he wanted to know very much what kind of value the system would make on the fire crystal rough, so after hesitating for a moment, he still put the fire crystal rough stone on the floor.

A burst of blue light swept over, and the system's prompt sound appeared in Lin Cheng's mind again: "Didi-A piece of unknown energy spar was scanned, due to the low purity and small size of the spar, the system price is 150,000 energy points!" Does the host perform the exchange? ”

"Redeem ...... Wait a minute! ”

Following the prompts of the system, Lin Cheng subconsciously planned to exchange it, but when he heard that this piece of fire crystal rough stone was set by the system at a sky-high price of 150,000, the whole person was instantly stunned, and after reacting, he hurriedly interrupted!

"A palm-sized Fire Crystal Rough Stone can be exchanged for 150,000 energy points? This...... Is there a mistake with this damn thing?! ”

After patting his cheek vigorously and making sure that he was not dreaming, Lin Cheng couldn't help but mutter, he had always believed that the potential of the fire crystal was very great, but he never imagined that this thing would be judged to be not ordinary when it came to the mysterious capsule system!

He still has a large number of Fire Crystal Rough in his storage capsule, and according to his current stock, if all of them are exchanged for energy value......

"At least 30 million ......"

Somewhat incredulously said this number, Lin Cheng's heart couldn't help but beat faster and faster, and the B-type enhancement potion that was once out of reach suddenly became within reach, which was like a legendary dream come true for Lin Cheng, who was bent on improving his strength!

The most important thing is that this is only the value of the fire crystal, in addition to the fire crystal, he also has a lot of black jade in the storage capsule, although it consumed a lot when building that black jade barrier, but the remaining reserves are still about the same as the fire crystal, even if the value is lower, but according to the system's evaluation standards, Lin Cheng is sure that those black jade can at least be exchanged for more than 10 million energy values!

"Lao Tzu sent ......"

Holding his hands tightly, Lin Cheng now only felt as if he had been hit by a windfall from heaven, this sense of unreality had always filled his mind, but his consciousness was very clear, telling him that all this was true!

"Redeem, redeem now! Type B strengthening potion, Lao Tzu is here! ”

With an excited face, he poured out all the fire crystals and black jade in the storage capsule, Lin Cheng couldn't wait to start his own exchange business, although this 'waste' of precious fire crystals made him feel a little distressed, after all, this thing is too rare, it can be said that one piece is less, but because of the stimulation of the B-type strengthening potion, he can't control so much at this time, and his mind is full of replacing the B-type strengthening potionist before anything else!

As he expected, the value of black jade was indeed about thirty percent lower than that of fire crystals, but Lin Cheng didn't care very much, compared to fire crystals of unknown value, the role of black jade was actually relatively single strictly speaking, so his first choice was black jade when exchanging it, and the fire crystal was left behind by him to wait for the black jade to be exchanged before using it.

But just when his exchange business was in full swing, a prompt suddenly sounded in his mind, and at the same time, a row of eye-catching red fonts appeared on the exchange panel: "The host's exchange quota for this month has been used up, please wait for the next month's exchange." ”

"Redeem the quota? This ......"

Looking at the row of dazzling red words in front of him, Lin Cheng, who was excited, was stunned for a moment, and hurriedly exited the exchange interface to look at the existing energy value list, only to find that there was an extra line of numbers below the original exchange list at this time, 10000000/100000000.

"One, ten, hundred, thousand, thousand, thousand, one hundred thousand, million, ten million, ......"

After counting these numbers little by little, Lin Cheng couldn't help but smile bitterly, this exchange system for a long time not only has a limit on the volume of the exchange, but even the amount of energy value that can be exchanged!

Looking at this exchange limit that seemed to pop up suddenly, Lin Cheng's face was speechless for a while, but the rules of the system were like this, no matter how dissatisfied he was, it was useless, so he could only collect the unredeemed fire crystals and black jade with a stupid face.

"What a bad daddy...... It seems like it's only the fourth today, right? ”

After putting away the fire crystal and black jade, Lin Cheng couldn't help but mutter, if he wanted to know that this exchange system still had a monthly quota limit, he would definitely upgrade the system before the end of last month, and now he couldn't get up or down, although the existing energy value was about to exceed 20 million points, but compared to the 50 million energy points required for the B-type strengthening potion, it was still a little far away, and if he wanted to continue the exchange, he would have to wait for more than 20 days!
