After a night of intense preparation, the formula of the new insecticide was basically determined, but Lin Wan was still not very satisfied with the insecticidal effect of this formula.

Because it was not early, the group of people who went to Nanshan to collect medicine yesterday did not pick back all the herbs in the herb list.

The herb that Lin Wan wanted to add the most was not among them, according to Qi Jun, this herb grew in the deep mountain forest.

In order to kill the insecticidal potion, when the medicine collection team came back yesterday, Qi Jun had already arranged it, and early this morning, some of the people in the medicine collection team had already gone to the depths of Nanshan to dig up the herbs that Lin Wan needed.

Although the killing effect of the new insecticide did not achieve the effect that Lin Wan wanted, the insect did not wait for anyone, so Lin Wan still confessed and made the insecticide potion according to the most feasible formula at present.

The first batch of new insecticides against pests was sent to the orchard before Lin Xiuwu arrived in Zhuangzi, and the second batch of pesticides is being urgently prepared.

Because a large number of herbs are needed, the manpower of the medicine collection team was temporarily increased to collect medicine from Nanshan.

From the Zhuangzi's potion making workshop to the orchard to Nanshan, the Zhuangzi of the Hou Mansion and the Zhuangzi of the Ye family in Zhennanhou Mansion moved from top to bottom, just to curb and kill pests.

The group of people who went to the depths of Nanshan to collect herbs, after collecting the first basket of herbs, they were sent back to Zhuangzi first, Lin Wan wiped her face with cold water, woke up, and continued to plunge into the intense blending test.

After some intense blending and testing, adjusting the formula and adding the potion after the new herbs, the killing rate of insect pests has been effectively improved, and the effect of quick killing is also very obvious.

It's just that the quantity of this herb is far from meeting the needs of insecticide production, and when the number of herbs cannot be satisfied, it can only temporarily retreat to the next best thing, and continue to make a large number of previous pesticides, which will first curb the spread of insect pests.

"Girl, now that the formula for the insecticide is available and the effect is seen, you should go back and rest quickly. Next, we'll take care of it. Although Qi Jun didn't sleep all night, Xu saw the hope of controlling insects, and his expression was no longer as anxious as yesterday, while arranging the dispatch from his hands? While urging Lin Wan, who looked tired, to go back and rest.

Lin Wan is indeed very tired? But she still couldn't let go of it in her heart, so she had to go to the orchard to determine the killing effect on the scene.

Although the new insecticide is not bad in the laboratory? The real insecticidal effect has yet to be verified on site? Before personally determining the killing effect of the scene, Lin Wanzi couldn't rest at ease.

"Take these potions with you? Let's go to the orchard first. Lin Wan pointed to the latest batch of laboratory insecticides.

Seeing Lin Wan's resolute expression, Qi Jun could only shake his head helplessly? Bringing the latest potion yourself? As Lin Wan walked out of the laboratory.

The two of them were about to go to the orchard with the testers who had been busy in the laboratory all night, when they were blocked by Cai and Lin Xiuwu, who came in a hurry.

"Sister Wan, you haven't rested all night? Heard that a new insecticide potion has been developed? If you don't hurry up and rest, where are you going? Cai quickly stepped forward and took Lin Wan's hand, his eyes fell on Lin Wan's face, and he saw the bloodshot green shadow under Lin Wan's eyelids, and he had an indescribable regret? There is more reproach in the rhetoric.

"Grandmother, Wanwan went to the orchard to see how the insects were exterminated? And he went back to rest. Lin Wan first patiently answered Cai's question, and then looked at Lin Xiuwu in surprise: "Didn't grandfather go to the Xishan camp?" How did you come here? ”

Lin Xiuwu glanced at Lin Wan: "Your aunt is not at ease?" So he sent a letter to the camp, and came to see it early in the morning. I also wanted to go to the orchard to see the pest situation and the effect of the extermination. Going together? ”

Lin Wan's heart warmed? I know the general idea in Lin Xiuwu's heart.

Father Ye and Ye Damin, who know how to plant best, are not there? Even if everyone in Zhuangzi knows that Lin Wan has also learned a good planting technique? I'm afraid that there will be people who don't listen to the command.

Lin Xiuwu proposed to go to the orchard at this time, not only to cheer Lin Wan up, but also to support Lin Wan.

Lin Wan glanced at Lin Xiuwu gratefully, and said to Cai's with a smile: "Wanwan will go to the orchard with her grandfather first, and grandmother will go back with confidence, and after seeing the effect of treating insects, Wanwan will go back to the room to rest." ”

Cai's brows couldn't help but tighten slightly, looking at Lin Xiuwu and then at Lin Wan, he had to sigh softly in his heart, but he didn't go back, and simply followed Lin Xiuwu and Lin Wan to the orchard.

Lin Wan pursed her lips and glanced at Cai's, knowing that Cai's mind had been decided, she didn't dissuade her, but when she rubbed to Cai's side, she kept a two-step distance from Cai's, and said with a smile: "Wanwan's body smells of medicine, and it doesn't smell good, so I won't help my grandmother." ”

Cai glared at Lin Wan: "Okay, I actually know that I have a smell on my body!" ”

Lin Wandan smiled: "How can you not know such a big medicinal smell?" So I hurried forward, lest I smoke my grandmother. You help your grandmother walk slowly, don't be tired of your grandmother! ”

The last words I said were to the maids who were waiting by Cai's side, and a few maids responded again and again.

Lin Wan didn't rub around Cai's side anymore, but quickly caught up with Lin Xiuwu and Qi Jun and the others in front.

The earlier you go to the orchard, the sooner you can see the effect of insect control.

Lin Wan plans to personally compare the killing effect of the insecticide prepared by the latest herbs with the insecticides prepared before on insect pests, if the gap is not too big, Lin Wan still plans to use the previous formula, after all, the herbs in the last recipe are difficult to collect and the quantity is not much.

Cai's was old and inactive, and when she rushed to the orchard with the support of the maids, Lin Wan had already entered the orchard and plunged into the intense comparative test, and even Lin Xiuwu, who had always been interested in practicing martial arts, also got into the orchard, and was following Lin Wan with great interest to watch Lin Wan command Qi Jun to deploy people to conduct experiments on two potions, and occasionally ask a few questions.

Lin Wan carefully observed the extermination of insect pests on the fruit trees, while answering Lin Xiuwu's question, the two stayed in the orchard for more than an hour, and when Lin Wan took the data he wanted, the ancestors and grandchildren came out of the orchard, and saw the Cai family sitting on the edge of the orchard looking at them angrily, and then remembered that the Cai family also followed them to the orchard.

Facing Cai's angry and angry gaze, Lin Xiuwu suddenly felt a little weak, and glanced at Lin Wan.

Lin Wan pursed her lips and smiled secretly, then walked two steps quickly to Cai's face: "Grandmother, our fruit tree is saved!" The insecticide developed yesterday is very effective in killing insects! ”

Looking at Lin Wan's smiling appearance, listening to Lin Wan's happy words, even if Cai's heart had many complaints, they all went away with the wind, leaving only Lin Wan's full of pity.
