Although Chen Yuanchao was reluctant, he still had to catch the morning train, so he couldn't say more and went out.

When her son's figure disappeared, Liu Yuping couldn't help but redden.

My son didn't know when he would come back when he left this time, Liu Yuping, who had been a son for the past ten years, was still very unaccustomed to the difference with her son.

"Okay, now that the third child has married a daughter-in-law, we can rest assured." Chen Changyuan stood behind him and patted his daughter-in-law on the shoulder and comforted.

Liu Yuping turned around and nestled into her husband's arms, rubbing her face against his chest, as if wiping away the tears that could not help flowing.

Chen Yuanyuan's hand was also on his daughter-in-law's shoulder and did not continue to speak.

Chen Yuanchao walked with Chen Zhanguo and Chen Weiguo, two bicycles, Chen Yuanchao rode one by himself, Chen Zhanguo Chen Weiguo rode one, and there was still a lot of luggage hanging on the bicycle.

At seven o'clock in the morning, the three brothers arrived at the train station, and Chen Yuanchao took the train ticket bought by an acquaintance and hurriedly got on the train, not having time to say goodbye to the brothers.

Chen Zhanguo and Chen Weiguo watched Chen Yuanchao leave, sighed, and turned to go home.

Chen Yuanchao left, but Su Lan's life continued, and she didn't wake up until three o'clock in the morning that day.

She didn't show any sadness because of Chen Yuanchao's departure, she was used to parting.

What's more, she will go to the army in another month or two, and now she has a lot of things to do, so she has no time to be sad about the difference between herself and men.

After Chen Yuanchao left, Su Lan fell into the enthusiasm for researching potions again, and Su Lan and Su's father researched insecticidal drugs again.

This insecticidal potion actually kills pests of crops.

Because the countrymen need to farm, the most precious thing is, of course, the crops, so for the harvest of the crops, Su Lan and they are researching medicines that can kill pests.

Then this drug was developed, which can actually be sprayed on crops to poison pests, which is similar to the use of chemical pesticides in later generations.

However, what Su Lan and they made was pure Chinese medicine, which was all important, and the poison made of herbs and herbs was harmful to the human body, but only needed to use antidotes to neutralize toxins or detoxify.

Just like those in ancient times, those who were poisoned could be detoxified with antidotes.

The insecticide made by Su Lan can kill insects, and when the grain is about to be harvested, the antidote will be sprinkled, and the toxins can be contacted.

When this kind of medicine was made, Su Lan and the others routinely gave the potion and prescription to the boss and asked him to do the experiment.

Of course, the people of the Mudstone Col Brigade believe in the Su family's factors, but this is a matter related to the rations of the whole brigade, so they can't be gullible, they are still waiting and waiting for the results of the above experiments.

The Su family was not reluctant, but they had to wait until they did the role before using it.

By the time the experiment was completed, it was already a month later, and the time had reached the sixth lunar month.

There has been news from the above that the potion made by the Su family is very useful, and after using the antidote, the toxins can be completely removed, and it will not poison people.

After receiving the news, the people of the Nishiao Brigade also began to use potions to fight insects, using insecticides and herbicides to remove insects and weeds from the crops.

In addition, Su Lan made a potion that could speed up the dissolution of fertilizer, so that the people in the mud and stone col could make fertilizer, and the fertilizer was very fertile, and the crops in the mud and stone col brigade grew very well.

After hearing about these medicines that are good for crops, the people in the surrounding brigades and villages also came to the door to ask for them.

The most precious thing for the croppers is their own crops, so they are all very happy that the Su family can make a medicine that has such a great benefit to the crops.

The people around came to buy herbicides, insecticides, and fertilizers, and the pressure on the Su family suddenly increased.

Su Lan found Chen Zhanguo, as well as Su Changfeng, and asked Chen Zhanguo and Su Changfeng to take the lead and set up a factory for making herbicides, pesticides, and fertilizers.

Because herbicides, insecticides, and chemical fertilizers are all things that are good for crops, and they are things that are too obvious, the Su family also used these prescriptions for an opportunity to develop a brigade, so they are not afraid that the establishment of a factory will be obstructed.

Chen Zhan Guo was very interested, and together with Su Changfeng, he joined other young people in the brigade to build a factory, and then Su Lan also said that the medicine collection to make these potions also needed human seeds.

Otherwise, how can there be a steady stream of crafting materials? Where can the light collect those herbs outside?

So Su Lan said that if people from Nishi Pass or even other brigades and villages can collect materials, and then replenish seedlings, or plant one or two of these medicinal materials in their own homes, the factory will buy them.

In this way, it can also drive the surrounding economy, right? And none of them wanted to occupy fertile land to grow herbs.

Because there are many mountains and forests in each brigade, many herbs can be planted under the forest, so herbs can be grown in the mountains.

The factory was established, and the follow-up of the cultivation of herbs was handed over to Su's father and Grandpa Su, and Su Lan was ready to join the army.

Because it took a month for the factory to do in just one time, adding up to Chen Yuanchao's two months away.

In fact, during this time, Zhao Dali and the others still wanted to make a move on Su Lan, but before they could do anything, they were put down by Su Lan. Although Su Lan is not going to kill, she has already abolished Zhao Dali's ability to act, and now Zhao Dali can only lie in bed and can't get out of bed.

Su Lan will not show mercy to this group of stubborn and undead people who want to attack her, she will not kill casually now, but as a person who has passed through the era when the morality and law of the last days have collapsed, she is very indifferent to accepting her fate.

The reason why she didn't kill Zhao Dali was only because she was troublesome, and the trouble involved in dying was not small. Of course, she could still create the illusion of an accidental death, but she wasn't going to do that right now.

Su Lan poisoned Zhao Dali and put him down, and he could only spend the rest of his life in bed in the future, and Zhao Dali's parents and younger brother were all poured down by Su Lan with a powerful nightmare potion. In the future, they can only be tormented by nightmares.

Of course, if a person who is tormented by a nightmare can't bear it and can't stand it and collapses and commits suicide, then it is not Su Lan's responsibility.

After indifferently dealing with Zhao Dali and others, Su Lan didn't care about Liu Liyun, who had always had little affection for her in Aunt Yang Hua's family, and Liu Liyun was not so bad to her, but after the last marriage proposal, Liu Liyun's hatred for Su Lan was full of heart.

In Liu Liyun's heart, she felt that it was because of Su Lan that her status in her in-law's family was so low, which made her husband more and more indifferent to her, and let her husband beat her last time.

So when Liu Liyun was educating her children, she would say bad things about Su Lan. The children also hated Su Lan very much with their mother, and after Aunt Yang Hua's family knew, they even restricted the children's contact with Liu Liyun, but unfortunately Liu Liyun was still in their house, so it was impossible to really let Liu Liyun not contact the children.

When they found out that Aunt Yang Hua was reluctant to teach Liu Liyun a hard lesson and educate her grandchildren, Su Chunli was reluctant to go back to her parents' house, she only needed to come back once during the New Year's holiday, and she didn't want to have more contact with her family who had become strangers to Liu Liyun.

And the Su family, Su Yuanzhi and Su Jimin are all human spirits, and of course they have also discovered the changes in Aunt Yang Hua's family, so they have also reduced their contact with Aunt Yang Hua's family, and they just treat them as ordinary neighbors to get along.

After all, people's hearts are biased, compared to Su Lan and Su Jimin's family, Liu Liyun is still the daughter-in-law of their family, and she gave birth to children for Su Chunming, so her heart is biased towards Liu Liyun. Once or twice, they will still stand on Su Lan's side, and over time, plus Liu Liyun will please her, and the wind blows well on the pillow, the heart of Su Mu's family will be biased towards her.

Decades of neighbors, decades of brothers, just like that, drifted apart.

But who hasn't been here that way? People's hearts are fickle, so Su Jimin and the others don't care about the estrangement of Su Mu's family at all, anyway, their family will not have a good face for Liu Liyun.

The relationship with Su Mu's family is not very close, and he gets along with ordinary villagers in the same village, and he also deals with Zhao Dali's family, Su Lan is ready to go to the army with the army.

Su Lan did not cut off contact with Chen Yuanchao for these two months, and after Chen Yuanchao returned to the army, he quickly obeyed the order and went to another place to serve.

After arriving there, Chen Yuanchao wrote a letter to Su Lan again, and then the couple resumed communication, and then Su Lanju received a letter from Chen Yuanchao asking him to join the army.

Because Chen Yuanchao had already settled down in the army, he also applied to join the army, and then the house arranged for Chen Yuanchao organizationally was also approved, and he waited for Su Lan to go to the army.

After settling the matter on the side of the mud and stone pass, Su Lan was ready to leave for the troops.

And the last time Chen Zhan Guo and Su Changfeng talked about the production of soap and soap, Su Lan also secretly told Chen Zhan Guo that it would be good to open a workshop in the factory where the medicine was made to make soap, and then sell it together.

After explaining everything clearly, Su Lan was ready to go to the troops.
