Chapter 17

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

The white light faded, 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. Seeing this, Lin Feng was almost frightened. Flipping through the screen carefully, Lin Feng looked dignified, and then he was pleasantly surprised.

This machine shows a super energy exchange system. There is a recovery slot on the left side of the machine. It says that the white crystals in the last days can be recovered, and the white crystals can be exchanged for some things.

The current exchange system is only one level, and there are not many things that can be exchanged. Lin Feng roughly looked at it, 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 Mithril long knife, Feng Ling sword, etc., the price is more than five thousand white crystals.

The second category is bloodline genes, and there are only two types, namely "mutated bloodline genes" and "enhanced bloodline genes". The mark on it is the bloodline gene that can grow, and the price is more expensive, requiring 20,000 white crystals.

The third type is potions. There are many kinds of potions, such as stamina potions and repair potions. From the description, Lin Feng saw that apart from some potions that can enhance the physique in a short period of time, they are some recovery potions. And the price is relatively cheap, ranging from a few hundred to a few thousand white crystals.

"This system is now at level one. It seems that as the level increases, more advanced items should appear."

Looking at the few convertible items above, Lin Feng secretly thought.

The above bloodline looks good, but Lin Feng doesn't know whether the bloodline gene change is good or bad, if it is changed to an animal, it will be troublesome. One is too expensive, but he is 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 behind?

After hesitating for a while, Lin Feng selected a bayonet from the weapon interface. This bayonet has no name, but the introduction is very special.

"This bayonet is an unnamed bayonet with a sharp blade. It is said to be made of extraterrestrial black iron. There is a hidden launcher on the top of the bayonet. It can fire Mithril needles three times. It is extremely powerful and can be refilled."

The price of the bayonet is 8,000 white crystals, which is much more expensive than those swords with gorgeous names above. And there is also a flying needle that can be fired, which makes up for the short bayonet. The price of just filling it once is 1000 white crystals, which is really not cheap.

Lin Feng had wanted to change to a decent weapon for a long time. The blade of the long knife that he took out from the supermarket before had already been unrolled when dealing with the second-level zombies. Ordinary weapons are really not suitable for dealing with zombies.

Although weapons like swords are a bit longer, in fact, the bayonet is the most useful in cold weapon warfare. Longer than a dagger, 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 watch, Lin Feng grinned.

Bai Jing, Bai Jing!

What Lin Feng needs most now is Bai Jing. After having this system, Lin Feng realizes that he is poor.

After two days of doing the task, with eight or nine thousand white crystals, Lin Feng really felt that he was a rich man. Those ordinary people are fighting for a few white crystals every day. Lin Feng had accumulated such wealth in just a few days, but after the exchange system appeared, everything changed.

Everything on the super energy exchange system is almost astronomical to Lin Feng, even a bottle of recovery potion costs 800 white crystals! Although the effect is much, much better than antibiotics, it can heal all traumas immediately. But it is too expensive, and most people can't afford it at all.

Expensive should have its benefits, right? Now Lin Feng can only comfort himself like this.

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

It is indeed made of Tianwai black iron, and the shiny black is chilling to see. Lin Feng reached out and grabbed the bayonet, feeling the chill coming from the knife.

Really good knife!

Seeing the bayonet, Lin Feng no longer felt sorry for the 8000 white crystals.

Touching the blade lightly with his finger, Lin Feng felt a tingling pain in his hand, and the bayonet actually cut Lin Feng's finger a little. The injured blood flowed onto the blade, and lines appeared.

Suddenly, Lin Feng felt the bayonet in his hand heat up, and then the blade trembled slightly, which seemed to be an expression of excitement.

The bayonet is actually spiritual!

Seeing the appearance of the bayonet, Lin Feng was extremely excited. He had seen the spirituality of weapons before in novels or on TV. Now seeing that the bayonet in front of him can tremble, it is obviously spiritual.

I found a treasure! Holding the bayonet in his hand, Lin Feng secretly rejoiced.

There was a button on the handle of the bayonet, and Lin Feng saw a small hole on the side of the handle facing the blade, which seemed to be where the silver needle was fired. Now Lin Feng doesn't want to test the power of the silver needles, after all, there are three in total, and 1000 white crystals are needed to replenish three silver needles. A silver needle with more than 300 white crystals, the power is not much worse. 300 white crystals are in the weapon shop at the base, enough to buy a bazooka.

Putting the bayonet into the doomsday watch, Lin Feng came to the living room. It was already evening, and Lin Feng saw Dou Yuxin sitting on the sofa. He held two white crystals in his hand, but the white crystals at this time had already dimmed.

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

Seeing Lin Feng coming out of the room, Dou Yuxin hurriedly said to him.

For Dou Yuxin, she was very grateful to Lin Feng. He saved Lin Feng from the first time he saw her. After Dou Yuxin's mother left, Lin Feng even 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 an elder brother, which is a wonderful feeling.

She did not hesitate to waste Bai Jing to practice for her. Dou Yuxin, who has lived in the apocalypse for nearly three years, understands how precious Bai Jing is. Not to mention so many white crystals, just one is enough for an ordinary person to live for three days.

After listening to Dou Yuxin's words, Lin Feng nodded. Dou Yuxin's cultivation speed is still normal, unlike her leveling up after absorbing a few white crystals. It must be something different between himself and others that made Lin Feng's upgrade so fast.

"Does it matter if it suits me because I have traveled through time?"

Since he couldn't think of any other reason, Lin Feng had no choice but to attribute the reason to this.

"hold head high!"

While Lin Feng was talking with Dou Yuxin, he suddenly heard a sharp voice. The sound was like the sound of the air defense siren in Lin Feng's original world, with a strong penetrating power.

"Boom!"

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