Just when the progress bar on the big screen reached 100 percent, a burst of white light covered the big screen.

The white light was removed, and a machine appeared in the center of the supermarket. Some look like ATMs with a screen on them.

Lin Feng didn't know why, so he stepped forward to check it out. This look almost scared Lin Feng. Carefully flipping through the screen, Lin Feng's expression was solemn, and then there was a surprise.

This machine shows a super energy exchange system, and there is a recovery slot on the left side of the machine, which states that it can recover the white crystal in the end times, and the white crystal can be exchanged for some things.

At present, the exchange system is only level 1, and there are not many things that can be exchanged. Lin Feng took a quick look, and now there are only three types of items that can be exchanged.

One is weapons, and all of them are cold weapons, such as the Mithril Long Knife, the Wind Ling Sword, etc., and the price is more than 5,000 white crystals.

The second category is the bloodline gene, and there are only two kinds, namely "Mutated Lineage Gene" and "Enhanced Lineage Gene". The above is marked as a growable bloodline gene, and the price is more expensive, requiring 20,000 white crystals.

The third is the medicine, there are many kinds of medicine, such as physical energy medicine, repair medicine, Lin Feng saw from the description that in addition to some to enhance the physique in a short period of time, it is some recovery medicine. And the price is also relatively cheap, between a few hundred and a few thousand white crystals.

"Now that this system is level 1, it seems that as the level increases, there should be more advanced items."

Looking at the few exchangeable commodities on it, Lin Feng said secretly.

The bloodline on it looked good, but Lin Feng didn't know whether the change in the bloodline gene was good or bad, and it would be troublesome if it was changed to an animal. It's too expensive to be in one, but I'm not worried about Qian Linfeng, there are so many resources in the supermarket, and he earned nearly 10,000 white crystals in just two days. With 10,000, will 20,000 be far away?

After hesitating for a moment, Lin Feng picked out a bayonet from the weapon interface. This bayonet does not have a name, but the presentation is very special.

"This bayonet is a nameless bayonet with a sharp edge. It is said to be made of extraterrestrial black iron, and there is a hidden firing device above the bayonet, which is capable of firing the Mithril Needle three times, and is extremely powerful and can be refilled. ”

The price of the bayonet is 8,000 white crystals, which is a lot more expensive than the sword with the ornate name above. And there are flying needles that can be fired, which makes up for the shorter bayonet. The price of just filling it once is 1000 white crystals, which is really not cheap.

Lin Feng had long wanted to change to a decent weapon, and the long knife he had taken out of the supermarket before had already been unwound when dealing with second-level zombies. Ordinary weapons are really not suitable for dealing with zombies.

Although weapons like swords are a little longer, in fact, in cold weapon combat, the most useful thing is the bayonet. It is longer than a dagger and shorter than a sword. Flexible and lethal at the same time, it is Lin Feng's favorite weapon.

After exchanging the bayonet, Lin Feng became a poor man again. Looking at the hundreds of white crystals lying in the storage space of the Doomsday Table, Lin Feng grinned.

Bai Jing, Bai Jing!

What Lin Feng needs most now is Bai Jing, and after having this system, Lin Feng knew that he was a poor man.

After two days of doing tasks, with ** Qianbaijing, Lin Feng really felt that he was a rich man. Those ordinary people are fighting for a few white crystals every day. And Lin Feng had accumulated such wealth in just a few days, but after the emergence of this exchange system, everything changed.

Everything on the Super Exchange System was almost astronomical to Lin Feng, even if it was a bottle of recovery potion, it actually cost eight hundred white crystals! Although it is said that the effect is much, much better than that of antibiotics, it can immediately heal all external injuries. But it's too expensive, and the average person can't afford it.

Expensive should have the benefits of being expensive, right? Now Lin Feng could only comfort himself like this.

After placing 8,000 white crystals in the recovery port, a silver light flashed, and a black bayonet appeared on another platform on the machine.

It is worthy of being made of extraterrestrial black iron, and the swarthy with light makes people feel chilled. Lin Feng reached out and grabbed the bayonet, feeling a chill coming from the knife.

Sure enough, a good knife!

Seeing the appearance of the bayonet, Lin Feng no longer felt sorry for the 8,000 white crystals.

Gently touching the blade with his fingers, Lin Feng felt a stinging pain in his hand, and the bayonet actually cut a small cut on Lin Feng's fingers. The wounded blood flowed onto the blade of the knife, and it was actually marked.

Suddenly, Lin Feng felt the bayonet in his hand heat up, and then the blade trembled slightly, like a sign of excitement.

The bayonet turned out to be spiritual!

Seeing the appearance of the bayonet, Lin Feng was extremely excited, the weapon had spirituality before, and he had seen it in novels or TV before. Now that the bayonet in front of me can tremble, it is obvious that it is spiritual.

Found a treasure! Holding the bayonet in his hand, Lin Feng was secretly happy in his heart.

There was a button on the top of the bayonet handle, and Lin Feng saw that there was a small hole on the side of the handle towards the blade, which was the place where the silver needle was fired. Now Lin Feng didn't want to test the power of the silver needle, after all, there were three in total, and it would take 1,000 white crystals to replenish the three silver needles. A silver needle with more than 300 white crystals is not far from powerful. 300 white crystals are in the weapons shop at the base, which is enough to buy a bazooka.

Putting the bayonet into the apocalyptic table, Lin Feng came to the living room. At this time, it was already evening, and Lin Feng saw that Dou Yuxin was sitting on the sofa at this time. He was holding two white crystals in his hands, but the white crystals were already dim at this time.

"I have absorbed five white crystals, reaching the level of a cultivator, and I feel that the speed is much faster than before."

Dou Yuxin saw Lin Feng coming out of the room and hurriedly said to him.

For Dou Yuxin, she was very grateful to Lin Feng in her heart. Saved Lin Feng from the first time he saw her. After Dou Yuxin's mother left, Lin Feng took her in.

Dou Yuxin could deeply feel that Lin Feng had absolutely no distracting thoughts about her. On the contrary, there is a kind of love for him similar to that of his brother, which is a wonderful feeling.

did not hesitate to waste Bai Jing to cultivate for her, Dou Yuxin, who had lived in the last days for nearly three years, understood the preciousness of Bai Jing very well. Not to mention so many white crystals, just one is enough for ordinary people to live for three days.

Listening to Dou Yuxin's words, Lin Feng nodded. Dou Yuxin's cultivation speed is quite normal, unlike upgrading after absorbing a few white crystals. It must be something different from others that can make Lin Feng's upgrade so fast.

"Does it matter if it's right for me to cross over?"

He really couldn't think of any other reason, so Lin Feng had to attribute it to this.

"Aang!"

Just as Lin Feng and Dou Yuxin were talking, they suddenly heard a sharp voice. That voice was like the sound of an air raid siren in Lin Feng's original world, and it was extremely penetrating.

"Boom!"

Just as that voice sounded, the door of Dong Wu's room opened, and Lin Feng was very flustered when he saw Dong Wu's appearance.
