Then Qiao Ya told Lu Yuan some things to pay attention to when raising livestock.
After learning everything, Lu Yuan left the dimensional space.
For the next period of time, Lu Yuan spent most of his time in the laboratory.
To prevent his location from being exposed, he specifically set up a very small space as his laboratory.
I don't have to worry about food and drink, but it's really lonely when I'm doing experiments.
Finally, after half a month, the first batch of bighead carp eggs were hatched.
Seeing that the large bluefish in the pond could easily survive after receiving a little oxygen, Lu Yuan breathed a sigh of relief.
"It's finally finished! Great! It seems this research can be preserved! It would be good to promote it extensively in the future!"
Next, Lu Yuan packed the fry of these large bluefish into a specially made box and took them back.
The news of Lu Yuan's return spread quickly.
Anna was the most excited. She was preparing lunch when she heard from her neighbors that Lu Yuan had returned.
He didn't even bother with the rice in the pot, putting down the spatula and rushing out.
When they arrived, Anna saw Lu Yuan surrounded by the crowd.
So she struggled through the crowd and got inside.
When she saw Lu Yuan open the box and explain to everyone, tears welled up in her eyes.
After not seeing him for many days, she worried every day that Lu Yuan might never come back.
Seeing Lu Yuan back now, I am naturally very happy.
So she rushed over and hugged Lu Yuan.
"I'm so worried about you, worried that you'll never come back!"
Anna cried as she talked about how much she missed Lu Yuan during this time.
Lu Yuan gently patted the other person's back: "Alright! It'll get better in the future! Perfect timing, let me introduce my product to you! A new type of fish, the bighead carp, rich in protein and fat, enough to supplement our nutrients, and its growth rate and survival capabilities perfectly meet our requirements! We're saved!"
However, Anna seemed to have lost interest in the matter; she was more concerned about whether Lu Yuan would go on adventures again after his return.
"Hmm! Let other people study these things!"
Helpless, Lu Yuan could only hand it over to other people for research. In any case, the fish eggs of the bighead carp had already hatched, and everything was ready. After experimental testing, these things fully met human survival needs and were suitable for large-scale breeding, and could become the next essential supplies for human survival.
Everyone happily began their research, and the army's supplies were finally secured, allowing them to focus on their studies with peace of mind.
So, after several months, the people continuously modified the underground city, introduced the groundwater, built fish ponds, and specially dispatched soldiers to protect these large bluefish.
They endured for months, and none of them had ever tasted the bighead carp. They knew that for every bighead carp they ate, they would lose hundreds of thousands of fish fry.
To Lu Yuan's surprise, although they brought the bighead carp fry, their lives seemed to be even more difficult than before.
Everyone patiently waited for the big bluefish to mature so they could eat the fish as soon as possible.
They used all their meager food to feed the large bluefish, and the fertilizer issue was also resolved. The soil was thoroughly improved, and the first harvest officially began.
Since Lu Yuan became a hero in this underground city, he and Anna did not need to do any work.
The rumbling sound lasted for a long time; it was the sound of the threshing machine threshing rice and various grains.
The air was filled with a strong aroma of wheat, making it hard not to take a few more breaths.
Everyone had been waiting for this day. As the saying goes, "It takes a thousand days to train an army for one day to use it," and the same applies to their planting of wheat and rice.
Although the growth rate of the various crops they grow now is different from before, the yield has increased, but the nutritional value is not as high as before, and the taste is even worse.
But these were life-saving foods, and everyone knew how important they were.
Being able to eat is already a great joy; no one would complain about the taste of the food.
Finally, after several days and nights of joint harvesting, the staff of the Grain Management Center convened the first citywide meeting.
Two hundred thousand people sat at home listening to the report, and everyone's face was filled with excitement.
Lu Yuan nodded in satisfaction: "It seems that we have completely solved the food crisis this time!"
Anna, leaning against Lu Yuan, sighed, "But don't forget, we didn't get a lot of ore from the Blue Star people last time, and we've almost used it all up! In a few months, we'll be launching an attack on Legion 77! I heard some bad news from the military headquarters yesterday!"
Lu Yuan was slightly taken aback upon hearing Anna's words.
"Has the military received the news?"
"Yes! The military has sent word that the Blue Star people are confirmed to be coming this October! It's already the end of September! It probably won't be long before we're fighting the Blue Star people again! The 77th Legion is considered a very capable force on Blue Star. You shouldn't go this time!"
Lu Yuan nodded. He had no intention of going to war. Last time, he just wanted to get some ore. Now that he had the ore, and he was sure that it could be used to make catalyst fertilizer, that was enough.
As for continuing to fight, Lu Yuan was not ready to fight. He was not afraid of dying, but he was worried that he would not be able to see Xiao Shan and his daughter before he died.
He was awakened by nightmares every night. In his dreams, he would recall what Xiaoshan and Qiqi looked like, but unfortunately, the images of his wife and children became increasingly blurry, and he even felt as if he could no longer remember them.
Every time he wakes up, Lu Yuan goes to his study, turns on his computer, and looks through the photos he took with his family.
Although that time was very difficult, Lu Yuan felt it was the most memorable period of his life.
Unfortunately, he has yet to find any clues about his family.
This time, he was even more eager to find clues about his family among the armies in the North; he had even had this premonition in his dreams many times.
