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

Because it was getting late, the group of people who went to Nanshan to collect herbs yesterday did not collect all the herbs in the herb list.

The herb that Lin Wan most hopes to add is not among them. According to Qi Jun, this herb grows in deeper mountains and forests.

In order to kill the insecticide potion, when the herb collection team came back yesterday, Qi Jun had already arranged it. Early this morning, some of the people from the herb collection team had already set out deep in the Nanshan Mountain to dig out the herbs that Lin Wan needed.

Although the killing effect of the new insecticide did not achieve the effect Lin Wan wanted, the insects did not wait for anyone, and Lin Wan still explained to make insecticide potions according to the most feasible formula at present.

The first batch of new insecticides for insect pests were sent to the orchard before Lin Xiuwu arrived in Zhuangzi, and the second batch of insecticides are being made urgently.

Because a large amount of herbs are needed, the temporary increase in the manpower of the herb collection group is going to Nanshan to collect herbs.

From Zhuangzi's potion making shop to orchard to Nanshan, Zhuangzi of Zhennanhou Mansion and Zhuangzi of Ye family, everyone moved from top to bottom to curb and kill pests.

The group of people who went to the deep south of the mountain to collect herbs, picked the first basket of herbs and sent them back to Zhuangzi. Lin Wan wiped her face with cold water, woke her up, and continued to devote herself to the intense allocation test.

After some intense preparation and testing, the formula was adjusted and the potion after adding new herbs, the killing rate of insect pests was indeed effectively improved, and the effect of quick killing was also very obvious.

However, the number of this herb is far from the need for insecticide production. When the number of herbs cannot be met, we can only temporarily settle for the second best. We will continue to make a large amount of previous insecticides to curb the spread of insecticides first.

"Girl, now the formula of insecticide has been available and the effect has been seen, so you should hurry back and rest. Next, leave it to us." Although Qi Jun did not sleep all night, maybe he saw the hope of treating insects, and his expression was no longer as anxious as yesterday. While arranging the dispatch to take care of him, Lin Wan, who was tired, urged him to go back and rest.

Lin Wan is indeed very tired? But she still couldn't let it go. She had to go to the orchard to determine the killing effect on the scene.

Although the insecticide effect of the new insecticide in the laboratory is pretty good? The real insecticide effect still needs to be verified on the spot? Before personally determining the killing effect on the spot, Lin Wan could not rest at ease.

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

Seeing Lin Wan's expression firm, Qi Jun could only shake his head helplessly? He personally carried the latest potion? He followed Lin Wan out of the laboratory.

The two of them took the test personnel who had been busy in the laboratory for a night and were about to go to the orchard when they were blocked by the Cai family and Lin Xiuwu who were rushing to the sky.

"Sister Wan, you didn't rest all night? I heard that a new insecticide potion has been developed? If you don't go to rest quickly, where are you going?" Cai quickly stepped forward and took Lin Wan's hand, his eyes fell on Lin Wan's face, and clearly saw the green shadow under the bloody nose in Lin Wan's eyes, and he felt indescribable regret. He only blamed him more in his words.

"Grandma, Wanwan went to the orchard to see the situation of insect extermination? Then she went back to rest." Lin Wan first answered Cai's question patiently, and then looked at Lin Xiuwu in surprise: "Didn't grandfather go to Xishan Camp? Why did he come here?"

Lin Xiuwu glanced at Lin Wan: "Your aunt is not at ease? She sent a letter to the camp and came to take a look early in the morning. I also wanted to go to the orchard to see the pest situation and the effect of killing. Let's go together?"

Lin Wan felt warm in her heart?     I know Lin Xiuwu’s general thoughts.

Ye Dad and Ye Damin, who know how to plant the best, are not there? Even people in the village know that Lin Wan has learned good planting skills? I’m afraid that someone will not obey the command.

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

Lin Wan looked at Lin Xiuwu with gratitude and said to Cai with a smile: "Wanwan and her grandfather go to the orchard first, and grandmother will go back with confidence. After seeing the effects of insect control, Wanwan went back to her room to rest."

Cai's brows tightened slightly, looked at Lin Xiuwu and Lin Wan, and had to sigh softly in his heart, but he didn't go back, so he followed Lin Xiuwu and Lin Wan to the orchard.

Lin Wan glanced at Cai, knowing that Cai had decided, so she did not dissuade her. She rubbed against Cai but kept a distance from Cai, and said with a smile: "Wanwan's body smells of medicine, which is not very pleasant, so she won't help her grandmother."

Cai glared at Lin Wan: "Okay, I actually know that I'm all full of smell!"

Lin Wandan smiled and said, "How can you not know the smell of medicine? I will go forward quickly so as not to get sick of my grandmother. Please help my grandmother and walk slowly, and don't get tired of my grandmother!"

In the end, I said it to the maids who were waiting by Cai, and the maids were repeatedly answered.

Lin Wan did not delay with Cai anymore, but quickly caught up with Lin Xiuwu, Qi Jun and others in front.

You can see the effects of insect control earlier when you arrive in the orchard earlier.

Lin Wan plans to personally compare the pesticides prepared from the latest herbs and the pesticides prepared from the previous ones. If the difference is not too big, Lin Wan still plans to use the previous formula. After all, the herbs in the last formula are difficult to collect and are not large in quantity.

Cai was old and rarely moved. When she arrived at the orchard with the help of her maids, Lin Wan had already entered the orchard and went into the orchard to participate in the intense comparison and experiment. Even Lin Xiuwu, who had always been interested in martial arts, also got into the orchard. She was following Lin Wan excitedly watching Lin Wan command Qi Jun to arrange people to conduct two kinds of potions, and occasionally asked a few questions.

While carefully observing the killing of insect pests on the fruit trees, Lin Wan answered Lin Xiuwu's questions. The two stayed in the orchard for more than an hour. After Lin Wan took the data she wanted, the grandparents and grandchildren came out of the orchard. Seeing the Cai family sitting next to the orchard looking at them angrily, they remembered that the Cai family also came to the orchard with them.

When Lin Xiuwu met Shangcai's angry gaze, he suddenly felt guilty and gave Lin Wan a look.

Lin Wan smiled secretly and took two steps to Cai: "Grandma, our fruit tree is saved! The insecticide developed yesterday is very effective in insecticide!"

Looking at Lin Wan's smile and listening to Lin Wan's words of joy, even if Cai's complaints were too much, they would go with the wind, leaving only full of regret for Lin Wan.
