It was a short crossbow, and it looked very similar to the one that Lin Feng had damaged before. The dark crossbow body and exquisite lines attracted Lin Feng's gaze firmly at a glance.

"The Luna God's Crossbow, which uses dark citrine as a power output, can cause fatal damage to fourth-level zombies and lifeforms of equal strength."

Under the beautiful picture, there is such a sentence.

Crystal Kinetic Weapons!

After seeing the annotation above, Lin Feng immediately felt that it was a good thing.

Aiming at level 4 zombies is early to prove fatal damage, that is, this short crossbow will also cause damage to level 4 zombies. Similarly, this weapon can kill people who are level 6 cultivators, and it can also injure level 7 cultivators.

Before, in the Tianheng Mountain Range, although Lin Feng was able to hurt Feng Si with a short crossbow, it was based on the situation that the other party underestimated the enemy. If Feng Si hadn't underestimated Lin Feng at that time, the previous short crossbow wouldn't have hurt him at all.

And Lin Feng's short crossbow had a disadvantage before, that is, it was used too few times.

Originally, it used white crystal as kinetic energy for a short time, but it was later forcibly used by Lin Feng. After a short period of use, it was scrapped due to a ruptured energy tank.

And this short crossbow uses dark citrine as the power output, and there is no restriction on its use, which means that it was originally designed for dark citrine as power.

Being able to injure fourth-level zombies and seventh-level cultivators was what attracted Lin Feng the most.

In the last days, ordinary ordinary weapons would not cause damage to cultivators. Even if it is a laser weapon, it has no effect on high-level cultivators.

Unlike the crossbow arrow, which uses crystals as energy, it is far more powerful than the ordinary weapons of this world. Being able to injure high-level cultivators and zombies is its greatest value, which ordinary weapons can't do.

But his price surprised Lin Feng, and he asked for 7,000 citrine.

Seven thousand citrine, that's seven thousand second-level zombies. Lin Feng has not seen many second-level zombies since he entered the end of the world, except for those in the corpse tide. If you rely on hunting to save it, I don't know how long it will take to save so much citrine.

But fortunately, Lin Feng passed the deal with Tang Palace. Got a large amount of citrine. Fortunately, the super exchange system has a transfer function, which can be connected to Lin Feng's personal account for transfer of money in the Doomsday Table, otherwise he really doesn't know where to find so many citrine.

Gritting his teeth, Lin Feng clicked the exchange button. Then seven thousand white crystals were paid through the doomsday table transfer function. Then there was a flash of silver light, and a pitch-black short crossbow appeared at the outlet of the Super Exchange System.

Picking up the short crossbow, Lin Feng felt that it was heavy. At this time, Lin Feng remembered that there was an introduction above, and this short crossbow was fired in bursts.

This short crossbow has a bolt reloader. It's not to reload one by one, but to load a hundred crossbow arrows at a time, just like the unit price.

The crossbow arrow is very small, according to Lin Feng's analysis, it should be designed in order to maximize its rate of fire and power, as well as the convenience of body installation.

When redeeming this short crossbow, the short crossbow itself comes with a hundred arrows, which are already loaded into the short crossbow. If you need to reload it after using it, you can exchange it for a crossbow box again from the Super Exchange System. A box contains one hundred arrows. Each box of crossbow arrows requires a thousand citrine.

Crossbow arrows are expensive, costing ten citrine each, but the materials used are extremely precious, both in terms of penetration and streamlining.

And the dark citrine is also added a hundred at a time, of course, the super energy exchange system will not add good dark citrine to the short crossbow, otherwise, Lin Feng can still earn it.

Originally, the price of the short crossbow was 7,000 citrine, and 100 dark citrine needed to be added. In this way, only the short crossbow body is installed. Lin Feng spent 17,000 citrine.

And the cost of each launch is one hundred and ten citrine, such a high price, it is definitely not something that ordinary people can afford.

According to the cost principle, if you use this short crossbow to kill zombies below level 3, you will lose money. Because the dark citrine produced by the third-level zombies is only enough for the cost of the kinetic energy emitted. The cost of the bolt will be compensated.

Such an expensive weapon is currently affordable for Lin Feng, but in order to ensure his own safety. It is worth spending so much money to improve the ability to protect oneself in the process of fighting powerful zombies. After all, money can be earned again, and making money is still very easy for Lin Feng.

Immediately after, Lin Feng exchanged for another piece of soft armor. The soft armor that was worn on Lin Feng's body before had already been broken when he encountered the female fourth-level zombie in the veterinary medicine market. That soft armor was redeemed here before the Super Exchange System was upgraded. Although it can be said to have some defensive power, it is still vulnerable in the face of powerful zombies.

The armor that Lin Feng exchanged for did not have a name, but it was introduced above that it could produce a certain degree of defense according to the amount of energy he had. The greater Lin Feng's energy intensity, the stronger the defensive ability generated by the armor. As Lin Feng continued to improve, so would his armor.

This is a growth type of equipment, but it is still necessary for Lin Feng. In the last days, no one can imagine what danger will be encountered. It is very necessary to have an armor to protect oneself, not to mention a growth armor.

The price of the armor is three thousand citrine, which is really not cheap. However, for his own safety, Lin Feng gritted his teeth and bought it.

Lin Feng found that since he had upgraded the super energy exchange system, all the new things he had seen had to be exchanged for citrine. But the price of the original thing has not changed, but this is the case with the new equipment.

Lin Feng said secretly, if it goes on like this, will it wait until the next upgrade, and everything in the super energy exchange system will be exchanged for dark citrine. It's just that the next upgrade costs a thousand XP, which means a thousand black beads. At present, the upgrade progress of the super energy exchange system is only five percent, and it is still very early before the next upgrade, so Lin Feng will not think about those distant things.

Putting the armor on his body, Lin Feng once again opened the bloodline interface in the super energy exchange system, which was also the most important part of Lin Feng.

The Demon Wolf Shadow bloodline gene that was exchanged before had brought great benefits to Lin Feng, although it was a bit difficult for Lin Feng to spend so much money at that time, but in fact, the benefits brought to Lin Feng were not measured by money.

Although improving agility is the most important effect, but without this bloodline, Lin Feng may not know what the result will be this time. If it weren't for the silver wolf killing the eight-clawed zombie, Lin Feng would not be the opponent of the other party at all.

And Lin Feng opened the bloodline interface just to see what changes would occur in the upgraded super energy exchange system. (To be continued.) )
