Although the sound of gunfire temporarily frightened the mutant crows, the crisis was not resolved, the crows hovered over the dense forest and were reluctant to leave, and Lin Lei did not dare to take to the air to fight, and the two sides could only stalemate like this.

After killing two injured crows that couldn't fly, Lin Lei harvested five mutant crow corpses, one of which was still second-level and had a crystal nucleus.

After checking the recovery price, the recovery value of the four first-level crows without crystal nuclei is only 0.08 contribution points, and the recovery value of the second-level crow is only 1.1 contribution points.

Sure enough, it is a systematic recycling style, not looking at the quality but only the weight.

"Looking at it like this, it seems that most of them are first-level mutant crows, and no trace of third-level mutant crows has been found." Lin Lei was very entangled.

If there is no high-level mutant beast, it means that there is not much recovery value, and this wave of mutant crows is worth forty or fifty contribution points at the top of the sky.

In addition, the crows are very timid, and it is estimated that a little more movement can scare them all away.

At this time, if the krypton gold is very likely to not recover the cost, it is really a shame to abandon the chicken ribs that are tasteless.

In fact, the larger the group, the more difficult it is to have a high-level existence due to the lack of resources, especially for birds and other groups that lack natural predators and are free to disperse.

"What to do? Is it true that it can't be automatically returned? Lin Lei was a little speechless.

Originally, I wanted to take advantage of the last day to make more money.

There was nothing he could do for a while, so he simply explored deep into the forest, hoping that the crows' patience would be limited and they would leave on their own.

Perhaps it was the arrival of the mutant crow that scared the mutant beast in the dense forest, and after walking for several kilometers, Lin Lei didn't find a mutant beast.

"Two hundred meters to the northwest, mutated pyrite was found, an ownerless thing, the host can be collected and recycled, and the recovery value is 5 contribution points per ton." The system found something good.

"Mutant Ironite? Will the ore still mutate? Lin Lei was very surprised.

What's wrong with this world? People can mutate, animals can mutate, plants can mutate, and now TM can even mutate mineral resources........

"The virus on this planet is not artificially created, the host can be understood as the planet is sublimating itself, and all the substances that exist on this planet are all changing, and the survival of the fittest is based on natural selection." The system explained.

A bit similar to the revival of the aura in the cultivation world, the mountains, rivers and rivers will all change to a certain extent.

Originally, all the mineral resources in this world belonged to the local government, but now there is anarchy in many places, and there is no transfer agreement for the previous minerals, so Lin Lei can't get it.

But this dark iron ore did not exist before the end of the world, and naturally it was not registered, which is the so-called ownerless thing.

"It's worth 5 contribution points per ton, what's the use of this thing, why is it so valuable?" Lin Lei asked as he headed towards the target point.

Equivalent to 1 million tons of raw ore, or the recycling price of the system, this thing is definitely worth more than rare earths.

"The basic materials for making energy-guided weapons, and they are general-purpose, and they are also strategic materials in other worlds. The host can be understood as the existence of a magic weapon. After the evolutionary of this world reaches level 4, with the help of weapons made of this material, the talent ability is at least 20% more powerful than if it is used empty-handed. The system explained.

The system needs Lin Lei to pay attention to this material, whether it is recycled or used to exchange with others, the system is the ultimate beneficiary.

"Good stuff! I didn't expect to be forced here by a flock of birds, but I got a windfall. Lin Lei sighed.

Luck is a real thing sometimes.

Soon, Lin Lei came to the destination according to the prompts.

In front of me is a black mountain peak about 100 meters high, and there is no grass on the mountain, which is very weird.

"So...... Still have kryptonite! Looking at the crows hovering in the sky, Lin Lei said helplessly.

If you want to be a miner with peace of mind, you can't do it.

"Through the scanning of this system, it is confirmed that the dark iron vein has only been formed for a short time, and the real dark iron ore is only about 150 tons."

Don't look at the big peaks, in fact, most of them have not yet completed the conversion, and they have to be taken away, and most of them can only be recycled according to the value of ordinary stones.

Let's not talk about whether Lin Lei has the ability to get them all away, it is not advisable to use this kind of desperate method.

"One hundred and fifty tons is also worth 750 contribution points, the system, you tell me how to recycle, you can't hold down a little bit by hand and take it away!" Lin Lei said.

The recovery tag can only mark creatures, and the creatures that need to be killed by themselves can be automatically recycled, and this kind of ownerless thing can only be recycled manually.

"The host can use a large mining machine, only 50 contribution points are needed, and without external interference, it can be collected in up to six hours. Another method is that the host cultivates to the stage of refining the gods, and under the shroud of divine consciousness, the ownerless things only need one thought, and they can be pocketed. ”

"If you want to mine with peace of mind, you have to deal with the crows in the sky, that is, you have to exchange for heavy armor, and you have to spend 450 contribution points at once. Then I might as well spend 288 contribution points and take the cultivation route of the strongest. Lin Lei calculated it carefully.

The first time I went out on a field job, I encountered so many strange scenes, who knows if I will encounter fairies and monsters next?

Although Lin Lei believes that in the material exchange area, there must be high-tech equipment to deal with immortals, but if he wants a piece of high-tech equipment that can make mortals kill gods, the price is absolutely sky-high.

It's better to take the cultivator route from the beginning, even if an evolutionary like Yang Xueli is equipped with the same high-tech equipment, his combat effectiveness is N times higher than Lin Lei's.

"If the host wants to enter the cultivator's threshold, he must first find a safe place, because when the host is promoted, it needs at least half an hour not to be disturbed in the middle, otherwise once he goes mad, he will be seriously injured and paralyzed, or he will die." The system warns.

Through systematic explanations, Lin Lei knew that it was impossible to cultivate here, even if there was no threat from mutant crows, he would not dare to rashly enter the path of cultivation in this dangerous world.

But Lin Lei will not be easy to comply, taking advantage of this moment when the crows in the sky do not dare to attack, he directly enters the material exchange area and selects cheaper air defense equipment.

In the end, Lin Lei chose a Guardian intelligent air defense machine gun, equipped with two sets of operating systems, manned and unmanned, intelligent friend or foe identification, 360-degree shooting without dead angles, six-barreled machine gun, 12.7 mm copper-shelled bullets, automatic loading ammunition, rate of fire of 10,000 rounds per minute, effective range of 4,500 meters, and the exchange price only needs 25 contribution points.

The energy supply method is still used in the nuclear energy crystal nucleus, and Lin Lei still has a backup here, so he did not spend any more contribution points.

The only flaw is that it costs too many bullets, but fortunately, 1 contribution point of copper-shelled bullets can be exchanged for 4,000 rounds, and Lin Lei exchanged 100,000 rounds of bullets in one go, so that he can fight for almost ten minutes.

As for the mining equipment, Lin Lei didn't choose it himself, because he had seen several relatively low-priced ones, either they needed to be operated manually, or the mining speed was slow, which did not meet his appetite.

As a big boss, how can anyone mine by himself?

As a big boss, millions of people every minute, how can you endure the existence of foreign workers, even if it is a machine.
