Qing Xiran believes that the difficulty of the Central Security Zone is actually not necessarily material, perhaps, it is possible that the person in charge of the Central Security Zone has changed, and the style of doing things will be different.

However, from this incident, Qing Xiran was told a very important information, that there was no way to supply the materials in the western region, so there were difficulties in the central security zone.

That means that the central security zone is heavily dependent on the western region.

This level of dependence can't be just weapons, there must be more things in it, materials? Or energy?

The largest use of energy in the Central Security Zone comes from crystal nuclei......

Thinking of Feihua in the western town, why is it in the western town closest to the western region? From the Mo Ru past incident, Qing Xiran knew that they seemed to be deliberately leading Qing Xiran to Xichen Town, so why did it have to be Xichen Town?

Because, the town of Xichen is closest to the west, and the headquarters of Feihua Biotech is in the western region???

Thinking of such a possibility, Qing Xiran, who was sitting in the window watching the rain, couldn't help but laugh "poof", and said to Luo Bei and Ah Jiu behind him:

"Cities in the central region, borrowing materials from S City, is also easy to solve, we have never done loss-making transactions, even if we have taken refuge in our S City, the materials given now will be returned to us with interest in the future, I think, this repayment plan can be carried out from now on."

In extraordinary times, it is very difficult, and it has just accepted a city in the central region, which is equivalent to opening a loophole in the central region, seeing that the materials are constantly being sent to the central region, and it will soon drag down the southeast region, then Qing Xiran will reverse the situation.

She got up, straightened her skirt, and said to the two of them:

"Loopholes can also be turned into windows, before we also had a small amount of trade with the Central Security Zone, all through Xia Mingyu's line, now, since the central ground cities have borrowed materials from S City, then if there is borrowing, there must be repayment, if there is no food, equipment and crystal nucleus, then use the corpses of mutated animals to pay it back."

All mutant monsters have their own usefulness, it just depends on whether humans have discovered their uses.

So far, after the team of chemical experts led by Lin Tao, all the southern mutant monsters that have been studied can come in handy, even the most venomous mutant snake, the snake gall is a treasure that can cure all poisons.

And the mutant man-eating plants in the eastern region are not to mention, so the mutant monsters in the central region can't have no effect, and the specific role is not good, this still needs to be studied, first all of them are collected cheaply, and then fed to the eastern region to feed the human-eating plants.

Speaking of this man-eating plant, it has now begun to be raised in captivity, because the mutant monsters in the eastern region, under the double attack of the survivors and man-eating plants, the number is already very small, so according to this biological chain, the survivors have a large demand for the rhizomes of the man-eating plants, and the man-eating plants will probably be less and less in the future.

But it is very difficult to raise man-eating plants in captivity, because although man-eating plants are plants, they eat flesh and blood, and Qing Xiran wants to raise them in captivity, so she can't feed them human flesh, so she has been discussing with ecological experts recently, should she issue an order to ban the hunting of mutant monsters in the eastern region?

Although the survivors now hate mutant monsters, they hate itchy teeth, but the ecological environment pays attention to a balance, if humans want to continue to have enhancers, they must have enough man-eating plant rhizomes, and to expand the production of man-eating plant rhizomes, they must be fed a considerable number of mutant monsters as food, in the final analysis, naturally only humans can only be forbidden to hunt mutant monsters, and even, it may be necessary to establish a mutant monster ecological reserve......

Just when Qing Xiran and ecological experts were discussing the ecological problems in the eastern region, this incident in the central region came out.

She turned to Luo Bei and Ajiu and said:

"You should find the city and garrison commander of S City, and negotiate a feasible repayment plan with them, after all, it is useless for them to keep the corpses of mutants, sell them to us cheaper, and reduce some of their debts."

Luo Bei and Ah Jiu immediately set out to do this, and indeed as Qing Xiran said, the corpses of mutant monsters are generally discarded directly after they have been dug up through the crystal nucleus, and there are also a few kinds of mutant monsters, which have been confirmed to be edible meat, but the utilization rate of this mutant monster is very low, and people generally only pick a certain part of the mutant monster's body to eat, and the rest of the head, internal organs, eyes, and brain...... This kind of thing is something that no one wants.

But man-eating plants eat everything, as long as there is flesh and blood, they do not pick their mouths, and even those bones can be melted by the liquid decomposed by their stamens.

So Luo Bei and Ah Jiu each found experts from their own teams and came up with a repayment plan for S City, half a ton of mutant monster corpses, which can be used to offset the arrears of one crystal nuclear coin.

Regarding the explanation of this plan [ ], Luo Bei and Ajiu's team wrote a contract as thick as a book, listed all the problems encountered in the repayment process in detail, and then sent someone to talk to the commander-in-chief of the urban management system and the commander-in-chief of the garrison system in S City.

But in fact, there is nothing to talk about, just when S City rebelled from the Central Security Zone and joined the central and southern garrison system, the garrison of S City signed a loan plan with Ah Jiu and Luo Bei for crystal nuclei and materials, no matter how much they used, this would be repaid with interest.

And although it is said that one crystal nuclear coin is worth half a ton of mutant monster corpses, this seems to be exaggerated, but in fact it is not, because the era base only requires weight, not the quality of mutant monster corpses.

This is also written into the contract.,The era base doesn't require how fresh the mutant monster corpse is.,Even moldy and rotten ones can be.,Those leftovers that other survivors don't want.,For example, eyeballs.,Nails.,Buttocks.,Mouth.,Together, you can get together to half a ton.,You can get a crystal of nuclear coins.。

What's more, the current mutant monster, not to mention weighing half a ton, is weighing more than a dozen tons, killing a ten-ton mutant monster can offset the debt of 5 crystal nuclei, not to mention killing, even if you pick up garbage on the ground in the central region, you can pick up the corpses of those mutant monsters that have not rotted yet.

Such a good thing, it is impossible for the commander-in-chief of the city management system and garrison system of S City not to sign, and even, for fear that the Times Base will regret it, they also hurriedly signed the contract.

As long as the cities in the central region come to S City to borrow supplies, the commander-in-chief of S City will directly ask those cities to provide them with the corpses of mutant monsters, and... The corpse of a 1.5-ton mutant monster with a crystal nucleus, so that S City can still make some money.
