The second half of the broadcast is still a touching deed in the rain. The mutual help of the territory from one to the twenty-eighth was also included, and Xia Qing smiled when he heard his name on the radio for the first time.

After turning off the radio, Xia Qing turned on the walkie-talkie.

Hearing that the casualties at the base were so serious, everyone's hearts were not good and at the same time they felt happy. Before their territory came out, they were all at the bottom of the base, living on the periphery of the security zone, they couldn't eat enough and didn't live well, and their physical fitness was much worse than now. If they don't come out, it's likely to be one of the tens of thousands of casualties.

Although they were hard and dangerous in their territory, they survived.

Converse Qingwei spoke first, "No wonder Team Tan called for support last night, but no one rushed over, and it is estimated that the management department thinks that we are the least need to send troops to rescue." ”

Everyone acquiesced to Concord's judgment, compared to the safe zone where tens of thousands of people died and the territory that had no ability to protect themselves, although there was a high-risk Evolution Tree here, the risk was indeed controllable.

Shi Ji asked, "I don't know if the evolution of the poisonous gas released by the yellow tiller tree is only like this in our few territories, or if this situation has occurred in many places?" ”

Tang Huai, who was well-informed, answered his question, "It's not just us, more than 20 territories with yellow tiller trees are directly empty, and only one person survives in our 21st territory." ”

Cong Qingwei hurriedly asked, "Does Brother Huai know how many territories have been empty this time?" ”

Tang Huai replied, "I haven't heard of it, it should be being summarized." ”

Shi Ji continued, "Because the yellow tiller tree blooms beautifully, we only started planting it decades ago. There are also wild sycamores, which are not native trees to us. You say, this time they have evolved aggressively, is there a reason for this? ”

Xia Qing, who was lifting the iron, stopped, she had never thought of Shi Yao's thinking angle, and it did sound reasonable.

The yellow tiller trees in the territory were planted by the people who lived here before the natural disaster, and there are no undeveloped mountain forests that have not been developed by humans, so there are no high-risk evolutionary yellow tiller trees on Mountain 49, otherwise their area will also be emptied.

Wild sycamore is an evolutionary species that only emerged after natural disasters, using bird droppings to spread its seeds around, and it is not a native tree species.

This question can only be answered by professionals. Zhang San rarely replied to professional questions, and Kuang Qingwei asked Li Si for advice, "Fourth sister, are you right when you say that you are old?" ”

Li Si calmly replied, "At present, the more convincing research conclusion from this perspective is that the native plants that are not much different after the evolution of Blue Star are indeed better than other species in their ability to resist the elements. As far as I know, there is not enough data to support the hypothesis that there is a high probability of dangerous evolution of introduced tree species. ”

"The concentrations of the elements are changing, the radiation problem has not been solved, and the blue star creatures are still evolving." Li Si paused for a few seconds and continued, "Human beings do not have a prominent advantage in the Great Evolution, and in order to survive, human beings must put aside their prejudices against each other and work together. ”

Li Si should have said this to Zhang San, and the lords did not dare to answer.

was silent for a long time, but Tang Huai couldn't hold back first, "Is Xin Yu here?" Your territory was the first to have a medium-risk evolutionary plant, can you tell us what kind of plant it is? ”

Just when everyone thought that Xin Yu would not reply, she spoke, just two words:

"Rose."

All......

Tang Huai continued to ask, "Is it already in your territory, or did you plant it?" ”

Xin Yu didn't speak again.

Roses are perennial woody plants, and when Xia Qing came out with the team to clean up this territory last year, there were no roses in the area of Territory 8.

Therefore, the roses in the No. 8 territory were raised by Xin Yu later. What kind of people will be in the mood to plant roses in the tenth year of natural disasters?

The military card did not pull the evolutionary plant from territory eight, which means that the medium-risk evolutionary rose plant in territory eight should not be large, and a few people can move it.

Roses are flowering plants, and there is a high probability that they will release poison gas after evolution, which should be the reason why Xin Yu classifies it as medium risk.

If this is the case, as long as there is an airtight protective suit, it is not difficult to find and clean up the medium-risk evolution rose in time, no wonder Xin Yu, who lives alone, did not call for support.

Zhao Ze asked, "You say, how about we clean up all the trees in the territory?" ”

Cong Qingwei replied, "We have at least thousands of acres of forests in several territories, how can it be so easy to clear?" Fourth sister, do you think this solution will work? ”

Li Si replied objectively, "The probability of dangerous evolution of a big tree that is already in the mature stage is relatively low, so there is no need to clean it up thoroughly." In addition, it is not practical to completely clean up the territory of woody plants, as many tree species rely on wind and animals to disperse their seeds. ”

Xia Qing agrees that many trees have tenacious vitality, such as wild sycamores, which have been cleaned up today, but as long as the temperature and humidity are right, they will come out again, and they must be cleaned regularly. The more open the place, the faster the wild sycamore grows.

The large trees in the buffer forests on the west and north sides of Xia Qing's territory are deeply rooted, and with them blocking the sun, it is difficult for the wild plane tree seeds that fall under the trees to grow stout even if they can germinate.

Everyone discussed for a long time, and there was no good way. The safest thing is to try to clean up the weeds and red-light saplings in the territory as much as possible, and plant more crops that have been cultivated and optimized by scientific researchers. The more green-light crops with a high safety factor are planted in the territory, the less likely it is that dangerous crops will evolve during the rain.

However, it is also unrealistic to plant in large quantities. If there is no strong strength like Zhang San, if you can build a greenhouse that can isolate the elements, a large amount of labor is required for mass planting.

Not to mention a lot, Xia Qing didn't want to increase alone, she chose to take the technical route to improve the territory's defense ability in the rain.

She has the stone, she has the weapon, she can't use the chainsaw in the rain, and she has to rely on manpower to remove the dangerous evolutionary trees. It would be nice if she had an exoskeleton that would both play to the strengths of a power evolver and protect her from the forces of reaction.

I don't know what special functions Yang Jin's new protective suit has, if the function is right and the score is not outrageous, Xia Qing must do a set. The most important thing at the moment is to clean up the weeds.

The next day, Hu Zifeng's team came over to help Xia Qing clean up the grass together, and the cleaning speed was greatly improved.

On the third day, Qi Fu also brought ten people over, and finally cleared the territory before the grass seeds matured.

Ally Qi Fu knows how to measure things, and the people he brought are all arranged to work in the south of the No. 3 territory, which is hundreds of meters away from Xia Qing's planting greenhouse, and the workers can only see Xia Qing deducting seven greenhouses from a distance, but they can't see what she planted and how it grows.

But even if they saw it clearly, these workers did not dare to have a crooked mind.

In the third rain, they witnessed Lord No. 3 rushing into the No. 5 territory like the wind, cutting down the evolution tree more than four meters high several times, and listening to the people in the No. 4 territory tell how Xia Qing slashed and shot hundreds of huge evolutionary water rats, and after the rain ended, they clearly saw the black smoke rising from the corpse of the No. 3 territory when it burned the water rat.

Lord No. 3 is as powerful as this, and it is a fool who dares to think crookedly.
