Although Lincoln had reminded everyone last night not to think that it would be invincible if they could shoot, and this morning's test also proved that the guns were somewhat destructive to mutant monsters, especially the boss monsters, but everyone, including Lincoln himself, was very excited when practicing shooting. After all, no matter how weak the guns were, they were more powerful than their bare hands.

Moreover, the automatic rifle can kill ordinary mutant monsters within 50 meters. It is only for this point that practicing shooting is valuable.

What's more, if a sister with a strong athletic talent has become a sharpshooter and even figured out the legendary "gun fighting technique", wouldn't she be even more invincible?

Unfortunately, my sister's talent in shooting can only be said to be very average. The person with the best shooting talent is Chu Dong, but it is not so shocking, it is just said to be the best.

Because Chu Dong and others could not do nothing and practice guns every day, they were familiar with the entire shooting process and were able to get on the target at a distance of 30 meters, and then stopped practicing and started other work.

Since they have obtained supplies from the underground supermarket of the Central Plaza, and a batch of military rations are also stored in the logistics warehouse of the nuclear submarine base next to them, they can no longer worry about food in a short period of time; since the mutant monsters are not zombies, they have no way to repair the city wall defense, so they can no longer worry about defense.

However, since firearms cannot be used in actual combat for the time being, and the problem of not being able to be supplemented in a short period of time must be taken into account, the use of the bones of ordinary monsters and BOSS-level monsters, the evolved trees, steel bars, steel pipes in the construction site, as well as various industrial finished products and semi-finished products with certain lethality will become an important task for them recently.

——Although the young spear made of ordinary iron pipes can even penetrate the bones in the eye sockets of the BOSS-level monsters, this is because the sister's strength is strong enough and her combat skills are high enough, which does not mean that this simple weapon that is not even shoddy and that is really easy to use.

In fact, it is very difficult to fight a BOSS-class monster with such a "soft" iron pipe. If the iron pipe is accidentally bent, its center of gravity will change, which will immediately make the user lose the "feel". Moreover, even if it happens to poke into the BOSS-class monster's eyes, it will only be pushed more by the bones in the eye socket, and it will not be able to penetrate it at all.

This kind of homemade spear cannot be used to block, or to chop or sweep. When picking, you should also pay attention to the strength and angle. If you want to penetrate the bones behind the eye socket, the direction of force must be consistent with the axis of the spear as much as possible, and accurately pierce the deepest part of the recess of the eye socket...

So if you have the conditions, my sister would certainly want better weapons. The restrictions on using ordinary iron pipe homemade spears to fight BOSS-level monsters are too great, and she always feels like she can't use them.

In addition, Lincoln also knows that several manufacturing materials are very easy to obtain, but even if you poke the Dogma, it will only display "good things" that "according to relevant laws, regulations and policies, some search results are not displayed", such as some cocktails made of sugar, rubber, gasoline, aluminum heater and other things...

In addition to patrolling the territory of this force, destroying invading monsters and creating weapons, another task that Chu Dong and others must do every day is to take care of various crops in the farmland and greenhouses.

When all the plants were growing wildly yesterday, the various crops in the farmland and greenhouses also grew a lot taller. The only old military doctor in the Chudong team who had agricultural production experience judged that these crops did not mature early, they just simply increased their volume. In this way, it is speculated that the fruits they finally bear should also increase their volume.

Originally, the old military doctor planned to turn the vacant land nearby to build buildings into fields, but Baohai's boss Zhao Fengheng and construction team engineer Wang Liang told him that the vacant land near the sea were actually filled with land reclamation, and the soil on the ground was full of raw soil with a very lack of humus.

So the old military doctor canceled the plan to farm nearby immediately, intending to plant some fruit trees on the nearby hillside after the territory that he could take care of was expanded, and then go to several nearby villages to replant various grain and oil crops on farmlands that are more convenient to irrigate. Vegetables may also be planted depending on the consumption.

As for the nearby open space, the wild plants that can grow in barren soil continue to "occupy" - those wild plants grow and wither on this land year after year, which will gradually thicken the humus layer on the surface and play a role in improving soil fertility.

However, there is still a question that Chu Dong cannot determine about plants - perhaps because the mutation rate of plants is very low, or maybe because the plants will not mutate at all, but will only evolve. In the territory of Chu Dong's team, no strange-shaped mutated plants have been found yet.

This should be a good thing for all surviving humans. It's fine to have the woods and flowers on the roadside. If 99% of the various crops in the fields become strange things, humans may have to take good care of the 1% of crops that have not mutated and then wait for them to re-plant seeds.

——Or, there will be a certain "Shennong" in the last days who risked being poisoned to taste the herbs and found some new edible plants from it.

Moreover, because the seeds of plants should have also mutated, it is also a considerable risk to remove the seeds stored in the granary, such as rice, wheat, corn, grains, soybeans, peanuts, sesame, rapeseed, etc., which have not yet lost their developmental ability, and then eat them. However, at that time, there will definitely be many survivors who have not considered this to act as Shennong.

In addition, as long as the plant has a chance of mutating, then eating the seeds stored before flashing through the red light will be risky. Even if the mutated rate of the plant is only one in ten thousand or one in ten thousand, the number of mutated seeds hidden in a granary... Let's calculate it now:

Suppose that the volume of a rice is ten cubic millimeters, then there will be one hundred rice in one cubic centimeter, one cubic decimeter will have one hundred thousand rice in one cubic decimeter, and one cubic meter will have one hundred million rice in one cubic meter.

Assuming that the variation rate of plants is one hundred thousand, then one thousand grains of rice will mutate in one cubic meter.

Finally, assuming that the volume of rice stored in a granary is 20 meters long, 10 meters wide, and 5 meters high - that is, 1,000 cubic meters, then there will be one million mutated rice seeds hidden in this granary!

Even if these mutant rice seeds that grow strangely, 99% are actually non-toxic, and there are 10,000 toxic seeds left, with an average of one in every 0.1 cubic meter. In addition, the toxicity is so strong that it is impossible to determine, and the toxicity of each toxic mutant seed may not be the same.

The size of a 50-jin meter bag is 0.77 meters long and 0.45 meters wide. Because the bag is sewn from two pieces of cloth, the circumference of the bag is 0.9 meters.

If you put 50 kilograms of rice into a circular bottom, the circumference of the bag mouth will not change, and the length will decrease. The reduced length is the radius of the bottom surface. It is known that the circumference of the bottom surface is calculated. The pi is roughly taken as 3. Then the length of the radius is 0.15 meters, and the remaining height is about 0.6 meters. Finally, the volume of the grain bag is about 0.04 cubic meters.

Considering the volume lost by removing the husk and grinding the rice into refined rice, the original volume of the rice milled rice is considered 0.05 cubic meters, so on average, there is one toxic rice seed in every two bags of rice.

Next... I can't evenly distribute the same amount of rice. Each time I cook, I only scooped and not scooped. The toxins I consumed cannot be evenly distributed to two bags of rice with a total of 100 kilograms, nor can I be evenly distributed to a bag of rice with a total of 50 kilograms. I can only distribute it unevenly into the pot of rice with a scooped out of toxic rice.

In the toxicity level, the lethal amount of highly toxic substances is less than 5 mg per kilogram, and the extremely toxic substances are 5-50 mg per kilogram. Even if a grain of rice with a volume of 10 cubic millimeters is ground into fine rice, the weight should be more than 10 mg. The rice that can be eaten by three people in a pot is about one pound of rice, six people have two pounds of rice, and nine people have three pounds of rice.

This means that if the toxin content of this toxic rice is high enough, even if the toxicity does not reach the extreme toxicity, it can poison the ten people in Chu Dong's team. As for whether it can be poisoned, it depends on how poisonous the mutated rice is, and on the other hand, it depends on how strong the physical fitness of the evolved humans is.

But even if the toxins taken every time are not fatal, they are worried about being poisoned every time they eat. On average, eating two bags of rice will definitely be poisoned once, which is something that no one can accept - unless they have no choice but to accept it.

In that case, before each meal, you will find someone first like the emperors and high nobles in the past... or animal tests for poison should be the only way.

It is precisely because of the risk of mutated edible plants that Chu Dong is very concerned about inspecting crops in farmlands and greenhouses. After he explained the truth to everyone in an extremely detailed manner, all fields that planted seeds before the end of the world will be strictly inspected over and over again, and the seedlings that were strangely grown will be removed immediately.

Moreover, everyone agreed that they would no longer eat the things that might sprout before the end of the world - such as complete corn kernels, beans, peanuts, sesame, potatoes, sweet potatoes, etc. The staple food should also be given priority to various grains that have been ground into powder to prevent the rice grains with very few germs in the essence rice from still having no damage.

Although this is completely over-care, there is no harm in being more careful. Anyway, the existing flour alone is enough even if they keep eating until they die. The total amount of flour eaten by the six million people in Binhai City is enough to eat 10,000 people for 600 days. Think about it carefully, what a huge number this is!
