Merit points are extremely precious, and they cannot be obtained by killing ordinary mutant beasts, and merit points can only be obtained by killing elite mutant beasts.

In addition to killing elite mutant beasts, merit points can also be obtained by completing system tasks, but the current system tasks have not been opened, so merit cannot be obtained by completing tasks.

Seeing this, Lu Fei nodded secretly, although the merit is precious, but after all, there is still a way to obtain it, and now being able to use the Treasure Pavilion is also very beneficial to Lu Fei.

Because the Treasure Pavilion does not have any restrictions on its use, as long as you have enough merits, it is a mythical martial arts and legendary martial arts, and you can also buy it for merit.

That's the power of the Treasure Cabinet.

On the other hand, there are treasure chests for sale in the Treasure Pavilion, which are a total of five treasure chests, namely black iron treasure chests, bronze treasure chests, silver treasure chests, gold treasure chests, and diamond treasure chests.

The Black Iron Treasure Chest only needs five merits to buy one, although the Black Iron Treasure Chest is in the lowest level of the treasure chest, but there is also a chance to open a mythical martial arts, if you are lucky enough to burst, maybe spend five contribution points, you can open a mythical martial arts, which is also the charm of the treasure chest system.

Lu Fei now has a little merit, and if he has four merits left, he can buy a black iron treasure chest.

Lu Fei is now wishing for a few more elite mutant beasts.

At the end of the battle, Lu Fei quickly cut open the head of the elite iron claw dog, and sure enough, in the head of the elite iron claw dog, a mutant spar was dug out.

This spar is a little different from the rest of the spars, because there is a green texture inside the spar, which is extremely eye-catching, and it is not mistaken, which is the unique feature of the elite mutant spar.

Lu Fei took the elite mutation spar, hesitated for a moment, and then put the elite mutation spar into the system interface and let the system recycle it.

Lu Fei is gambling to see what will happen to the elite mutant spar after it is recovered by the system, whether it will turn into a success medal or a gold coin.

"Recover a Tier 1 Elite Mutant Crystal and get a little merit. ”

Lu Fei's eyes lit up immediately.

The elite mutant spar can indeed be exchanged for merit, although it can only be exchanged for a little merit, but for Lu Fei, it is already a shortcut to exchange for merit.

Although the price of the Elite Mutant Crystal on the market is relatively expensive, nearly ten times more expensive than the Mutant Crystal of the same level, there is at least a way to buy it in small quantities.

Lu Fei can use ordinary mutant spars to exchange for elite mutated spars, and then use elite mutated spars to exchange for success spars.

Thinking of this, Lu Fei was already nodding secretly with a happy face.

The corpse of the iron claw dog is also a treasure, so naturally it cannot be given up, and it can be sold for a large price after bringing it back.

After the battle was over and the battlefield was cleaned up, Lu Fei was worried about Li Mengxue's safety, so he didn't have the heart to continue fighting, and hurriedly returned to the center where the blade grass was located.

Li Mengxue is still in a coma, but seeing that her breathing is stable and her face is ruddy, there should be no big problem, according to Lu Fei's guess, it should be that after Li Mengxue was poisoned, she used some secret technique to let herself fall into a state of hibernation, from the onset of snake venom, although the snake venom has been lifted later, but she fell into a state of secret art and could not wake up.

Although Lu Fei was a little worried about Li Mengxue's state, at this time, he was also powerless.

However, Lu Fei still bought a five-grain pill and put it in Li Mengxue's mouth.

The five grains produced by the system are amazing, put it in your mouth, and it will melt in a moment, but you don't have to worry about swallowing it.

Seeing the Wugu Pill being melted in Li Mengxue's mouth, Lu Fei was also a lot more relieved, at least he didn't have to worry about Li Mengxue being starved to death.

A Wugu Pill can provide a day's energy needs, but Li Mengxue just stays still, and her own consumption is also very small, it is estimated that one Wugu Dan is enough for her for three days.

After making sure that Li Mengxue was fine, Lu Fei also took the opportunity to rest for a while and took a nap, about an hour.

When Lu Fei came to his senses, the whole person also became energetic, and all the energy consumed in the previous battle had returned.

Lu Fei checked the injuries on his body again, almost all of the injuries on his body were made by the iron claw dog, he had been treated with the system flying gold sore medicine before, but the system gold sore medicine was also easy to use, and the effect was remarkable, and by now, the wound was already scarred, and it would be recovered in a few days.

Lu Fei thought about it, and ate all the three martial arts experience pills that the system gave him, and the martial arts experience he converted into was all used on the shadowless feet.

In the battle with the Iron Claw Dog, Lu Fei just suffered a loss of not enough speed, so this time, the first thing to improve was the Shadowless Foot to make his speed faster.

After the three martial arts experience pills went down, the intermediate-level Shadowless Foot immediately increased its experience value by another section, and it was not far from being promoted to the advanced level.

Lu Fei glanced at his gold coins and decisively purchased two Martial Arts Experience Pills.

These two Martial Arts Experience Pills were all used on the Shadowless Feet.

With a ding, the shadowless feet were finally promoted to a high level.

Upgraded to the high-level Shadowless Foot, the attributes have improved slightly, but it is obvious that Lu Fei's speed has become faster.

There are more experience points required to upgrade to the advanced level, so the shadowless foot will not be upgraded for the time being, and now it is necessary to concentrate on upgrading the three-point swordsmanship, and first upgrade the three-point swordsmanship to the advanced.

Lu Fei adapted to the use of the Shadowless Foot on the spot, and waited until he was able to control the current Shadowless Foot freely, then he left Li Mengxue and walked out of the blade grass again.

Walking out of the blade grass, Lu Fei returned to the location where he killed the flying needle hedgehog before, and then took out the corpse of a flying needle hedgehog, and then took out the monster attraction pill rewarded by the system, and put the monster attraction pill into the corpse.

This is the correct way to use the Monster Attraction Pill, which can only attract flying needle hedgehogs, and for the rest of the mutant beasts, it will not be attractive.

Lu Fei hid in the grass next to him and waited with peace of mind.

In less than five minutes, the effect of the Monster Attraction Pill was brought into play.

One by one, the flying needle hedgehog, as if crazy, ran towards the body of the flying needle hedgehog left on the ground.

The Monster Attraction Pill is used in the corpse of this flying needle hedgehog.

The flying needle hedgehog, which was attracted over, kept circling around the corpse on the ground, and from time to time used his nose to sniff the corpse.

The number of flying needle hedgehogs began to increase, and in a short time, hundreds of flying needle hedgehogs have gathered here, and more flying needle hedgehogs are coming from afar.

"Okay, that's fine. ”

Lu Fei nodded, swallowed ten times the experience pill, held the long sword, and already rushed towards the flying needle hedgehog.
