Bringing the Supermarket to the Apocalypse Chapter 161: Exchange system

Black beads are produced in the brain of Rank 2 zombie, Yellow Crystal should normally be produced in the brain of Rank 2 zombie, and black beads will be produced only with a very small probability. `

This black bead has no effect on others, and there is no energy fluctuation in it. In apocalypse this thing is worthless, not even as good as a White Crystal.

But this black bead is useful for Lin Feng, and the energy exchange system in the city can be upgraded with black beads. At present, the upgrade progress bar display of the energy exchange system in Lin Feng is 1%. That was the last time Lin Feng was used for experiments. A black bead can bring 1% progress to the energy exchange system.

When the robbery was encountered outside the Northern Mountain base, Lin Feng received some black beads. Plus today's corpse tide produced, Lin Feng has a total of 150 black beads on hand. This amount is enough to upgrade the exchange system.

Back in the room, Lin Feng entered the city. Before coming to the exchangeable system, he did not hesitate to put all the black beads into the recovery port of the exchangeable system.

When the exchange system first appeared, those things in it were already very powerful. Not to mention, the black iron bayonet of Lin Feng's is already extremely sharp, and it used Lin Feng to escape many dangers.

And the benefits of lineage Bloodline to Lin Feng's in the exchange system are great. Not to mention that his own attributes are agile improvements to Lin Feng. It is very strange to let the mutant wolf help him before. `

And what will happen after the upgrade of the exchange system, Lin Feng is looking forward to it.

A flash of silver flashed through, and the progress bar on the exchangeable system continued to rise until the percent was reported, and the silver flash appeared. After the silver light passes, the progress bar display on the system can be exchanged to 51 / 1ooo.

It seems that the next upgrade requires a thousand black beads to complete. The chance of black beads appearing is small. I did n’t expect that the next upgrade would require so many black beads, which made Lin Feng smile.

But now Lin Feng doesn't have time to think so much, and quickly came to the screen. Lin Feng is ready to see what the upgraded exchange system looks like.

As before, there are still several categories on the exchange system, which are used to exchange different kinds of things. But Lin Feng sees, except for those things that were originally there. There are more new things.

First, the weapon exchange system. Originally there were some cold weapons, but now there are more technology weapons. `

For example Nuclear magnetic Gun, and frequency shock pulse gun.

Nuclear magnetic Gun is a weapon that is high level more than a laser weapon. It costs 10,000 White Crystal in apocalypse. It is an extremely lethal weapon. Even Cultivator can be injured.

Despite its great power, most people can't afford it. Ten thousand White Crystal is not everyone can have, only a few Cultivator, can barely have so much money. Therefore, it is almost impossible for ordinary people to use Nuclear magnetic Gun to kill Cultivator. The threshold of Nuclear magnetic Gun is too high, and it is simply not what ordinary people can reach.

In the exchangeable system, this kind of Nuclear magnetic Gun requires one hundred Yellow Crystal. Although it is similar to the market price, there are still differences.

Nuclear magnetic Gun is very rare in apocalypse, and few people can sell it. Sometimes it is even rich. It is not necessarily available. This is like the limited-edition weapons of Lin Feng previous life. The number of weapons is very small, and they are not readily available. Otherwise, the former Feng Yi of the Eastern Mountain base used 100 million White Crystal to buy 100 Nuclear magnetic Gun, which is still very effective for the base's strength.

Due to the extremely small number, the price of Nuclear magnetic Gun has even doubled in the black market of some bases. But because the price is too high, few people will spend money to buy this weapon.

The Lin Feng is different. The prices in the exchangeable system are all fixed. And based on past experience, there is no limit to what can be exchanged.

That is. Lin Feng can be exchanged for Nuclear magnetic Gun at a price of one hundred Yellow Crystal in the energy base system without restrictions, and then sold at an increased price. In that case, you can make a lot of money.

But Lin Feng does not want to do this, although it would make money. But this way Nuclear magnetic Gun will be circulated on the market. With such a powerful weapon, it is not necessarily a good thing to circulate it.

However, Lin Feng still exchanged ten Nuclear magnetic Guns into Apocalypse Watch in case of unexpected needs.

It ’s strange to say that things in the city ca n’t be taken out of Apocalypse Watch, but things taken out of the exchangeable system are an exception. Before Lin Feng experiment, the potions exchanged from the exchangeable system are not counted. Can be taken outside.

The frequency shock pulse gun is indeed a wonderful thing, he will not cause any harm to the human body and zombie, but it has great power for the building. Under the power of the frequency shock pulse gun, the surrounding walls of the general base will be collapsed by this weapon.

Frequency shock pulse gun is not something in this world, Lin Feng has never heard of this weapon before. But there is this thing in the exchangeable system, which is an exception.

Although Lin Feng would like to exchange a frequency shock pulse gun, and then use it to destroy all the walls of the Eastern Mountain base. But the price of this weapon is too high, even 10,000 Yellow Crystal. Although I really want to get it, Lin Feng can only stop.

At present, there are only more than 31,500 Yellow Crystals in Lin Feng's hands, of which 30,000 Yellow Crystal was exchanged for diamond rings at Tianlong Base. The other 1,500 Yellow Crystal were obtained from the corpse wave just now. After exchanging the ten Nuclear magnetic Guns, there were only 5oo left for the 1,500 Yellow Crystals.

If you spend so much Yellow Crystal just to collapse the opponent ’s wall, it ’s not worth it.

Lin Feng has just sold a batch of diamonds, which should not be digested yet. If at this time he uses diamonds to find Martial God Auction House for Yellow Crystal, the possibility is somewhat unlikely.

Lin Feng will spend money on the blade, this weapon is too luxurious for the current Lin Feng. Now what he most desperately needs is to improve his strength, even if he can't reach 8th grade Cultivator at once, he must be the best among 7th grade Cultivator. Otherwise, for other high level Cultivator, Lin Feng will still be dangerous. Only by ensuring your own strength can you survive well in apocalypse.

And then, Lin Feng now has a weapon in the weapon interface on the redeemable system. When he saw this weapon, Lin Feng immediately felt his eyes shine. This weapon gave him a feeling of deja vu. (To be continued.)
