On the tenth year of the natural disaster, I went to farm with me

As the leader of the danger investigation team, Tan Junjie is of course aware of how abnormal the combat power of Robinia is. "Aggressive Robinia is a high-risk plant. The area within a radius of 200 meters is the effective attack zone of Robinia. All personnel in Territory No. 4 will immediately evacuate the effective attack zone and wait for the investigation team to come over and deal with it."

"Got it." Zhao Ze's voice was filled with tears. "There is a shed within the attack range."

After listening to Zhao Ze's words, Xia Qing knew which locust tree No. 4 was attacking and killing.

Earlier this month, allies of the Territory Alliance also ate coarse grain steamed buns made by Zhao's mother using the yellow locust flowers that bloomed on this locust tree.

If it was the old Tang Huai, he would definitely confront Zhao Ze and ask him whether he wanted life or food. Tang Huai, who had now started to work hard on farming and raising insects, felt distressed when he heard that Territory No. 4 was about to lose a greenhouse of crops.

Tang Huai had such thoughts, not to mention other lords.

Tan Junjie, who had to protect the personal safety of the people in the territory and the farmland as much as possible, asked, "How many meters away is the greenhouse from the attacking acacia?"

Zhao Ze responded with a tearful voice, "It's more than 180 meters away. Captain Tan, can the personnel in my territory wearing level protective clothing clear the crops in this shed? There is an acre of green lantern mung beans planted in this shed, and they have already bloomed and grown pods."

Tan Junjie asked, "What is the crown radius of the Robinia tree now?"

Zhao Ze replied, "I estimate it to be about 8 meters, definitely no more than meters."

Xia Qing, who had already entered Shed No. 6, quickly calculated the various attack indicators of Robinia while clearing the plants that were killing the evolutionary plants:

The horizontal distribution radius of the Robinia pseudoacacia root system is about twice the radius of the tree crown, that is, the area around the Robinia pseudoacacia tree is 2 meters (or 16 meters for safety reasons) a high-risk area and must not be entered. If you enter a high-risk area, you may step on the roots of the Robinia pseudoacacia tree, triggering an attack.

180 meters, although within the effective attack range, is a relatively low-risk area.

Relatively low, but not without risk. Even if no one actively triggers it, the branches of the acacia tree may be broken by the wind or pierced by its own thorns, triggering an attack. Once triggered, the rainproof cloth of the greenhouse will be shot into a sieve and the arch support will fall apart.

One can imagine the danger faced by the people inside.

Tan Junjie answered cautiously, "The wind is not strong now. People wearing level 3 protective clothing can enter the greenhouse, but they must carry shields and be on guard against attacks by acacias at any time."

Zhao Ze immediately perked up, "Got it."

Afterwards, Tan Junjie called Yuan Rui on the investigation team channel and asked him to take three people into territory No. 4 and set up a cordon 200 meters around the acacia tree.

It seems that Tan Junjie intends to adopt a conservative approach. Because there is a greenhouse within the attack range of the big tree, it will be damaged if it is removed immediately, so he plans to wait until the heavy rain stops and then use the cannon to blow it up.

Use Yi Stone to drive away the harmful elements and prevent the harmful evolving Robinia pseudoacacia from continuing to grow?

Even if they wanted to use the Yi Stone, they couldn't build a rain shelter for such a large tree in a short period of time. Moreover, the Yi Stone was not very effective in removing the harmful elements in the deep soil. Even if they built a rain shelter, they couldn't completely prevent the growth of the harmful evolution tree.

If you accidentally step on the spreading roots of a big tree while building a greenhouse, it is likely that the tree will spray out thorns longer than your palm.

The task of setting up a cordon is simple, and there is no need for the evolvers in the territory to go for support. But Xia Qing thinks this method also has certain risks: it is now the second rainy season, and the locust trees are full of pods. If they are allowed to continue to grow, if the pods mature and fall off during the rainy season, it will cause the high-risk plants to spread.

Therefore, we should clear the acacia trees now. Xia Qing already had an idea about how to clean them up. She did not talk about it in the investigation team channel, but sent a message to Tan Junjie.

Tan Junjie is the team leader of the investigation. Whether he adopts the suggestions put forward by Xia Qing is not up to Xia Qing to decide.

After sending the message, Xia Qing continued to clear out the evolving plants.

After the second round of red-level killing rain ended, Xia Qing immediately began to patrol the buffer forest in his territory.

There are hundreds of mature trees with thorns in the 4500-mu buffer forest of Territory No. . After a tour, Xia Qing was sure that these trees were very peaceful and showed no signs of aggressive evolution.

When reclaiming the farmland, Xia Qing took into account the damage that these trees would cause to the farmland if they evolved aggressively. Therefore, there was not a single thorny tree within 500 meters of her farmland. Even if the trees in her territory evolved aggressively, they would not be able to damage her rain shelter by launching physical attacks.

After visiting the buffer forest, Xia Qing was about to go to the ninth territory for a tour when he heard Tan Junjie ask in the lord channel, "Xia Qing, are you there?"

Xia Qing pressed the intercom button, "Yes."

"If we erect a wall made of tarpaulin to the west of the greenhouse in Territory No. 4, how many layers of tarpaulin do you think it would take to block the thorns of the acacia?"

It seems that Tan Junjie is going to adopt her plan. After building the anti-thorn wall to protect the greenhouse, it will not be difficult to clean up the acacia tree.

Xia Qing immediately replied, "Three layers of rainproof cloth can ensure the safety of the greenhouse."

Tan Junjie responded, "Okay. Zhao Ze, before we clear the high-risk tree, we need to build a four-meter-high tarpaulin wall to block the shed within the attack range. Do you have enough materials in your territory?"

"Not enough." Zhao Ze made a request in the Lord's Channel, "Brothers and sisters, do you have two unused rainproof sheets, sturdy five-meter-high wooden sticks, iron frames or steel bars in your territory? I want to rent them to build a thorn-proof wall."

Xia Qing was the first to answer, "I have fifteen steel bars with a diameter of 15 mm, ranging in length from 3 to 8 meters, as well as a whole piece of rainproof cloth from the greenhouse that was replaced in March, and twenty-five five-meter-long hardwood sticks. I'll use the tiller to pull them over to you later."

"Thank you, Sister Xia Qing." Zhao Ze's voice choked.

Huo Lei spoke up, "I have 3 steel bars of 8-33 meters, 13-23 mm thick, I will carry them over."

Qi Fu, Kuang Qingwei and others also followed suit and soon gathered enough supplies to build the anti-stab wall in Territory No. 4.

The territories that were nearby had to be carried over by people, while those that were far away had to wait for Xia Qing's micro-tiller to pull them over. After they were over, everyone lent a hand and helped build the anti-thorn wall for territory No. 4.

When building the wall, everyone's scalp tingled when they heard the rustling sound of leaves in the wind. They were afraid that the thorns on the locust tree, which were longer than the palm of their hand, would suddenly shoot out and prick them. This fear did not disappear just because they were wearing the third-level protective clothing for outdoor use.

Even Xia Qing, who was wearing a special protective suit and a snakeskin coat, felt her scalp tingling, and even felt a dull pain in her left arm, which had been pierced by a spike. (End of this chapter)
