In the past three years, the crops grown by Yun Ruoyue and the others have become more productive year by year. Yun Ruoyue has also taught many modern production techniques to everyone, which is great.
The land improved South Vietnam's production efficiency.
More and more Chu people are coming to South Vietnam, and everyone gathers here to build South Vietnam together.
Yun Ruoyue and Chu Xuanchen help others, not by giving them food directly, but by teaching them to be self-reliant and letting them rely on their own labor in exchange for food.
In this way, people will work hard and understand the principles of self-reliance and struggle.
Today's South Vietnam, with the unity and concerted efforts of the people, has become rich in materials and very prosperous.
The number of elite soldiers under Chu Xuanchen slowly increased from a few thousand to 50,000.
Moreover, the quality of these 50,000 Zhennan Army is not inferior to that of the previous Xuance Army. With these soldiers, no one in South Vietnam will dare to invade again.
Not only that, Chu Xuanchen often led his soldiers to help the people. They helped the people pave roads and build bridges and solve difficulties.
Chu Xuanchen also sent people to build many large ships, and then specially selected sailors with good water skills to go fishing at sea. Not only that, they also developed a navy to prevent the invasion of foreign enemies.
Chu Xuanchen also built many docks and ports on the seaside, and then transported South Vietnam's materials to surrounding countries and regions through sea transportation, and conducted trade with others, exchanging his own materials for other people's materials.
Not only that, Yun Ruoyue also taught everyone how to conduct sea farming on the sea, which can increase fish production.
They also re-planned cities according to local conditions, planned streets, repaired rivers, dams, water control, etc., to make South Vietnam orderly, clean and tidy.
They took in refugees, established maritime restrictions, fought against bandits, developed agriculture and commerce, and slowly turned South Vietnam, a poor place, into a land of prosperity.
Yun Ruoyue and Chu Xuanchen also built many charity halls to adopt homeless orphans.
The two also funded the construction of a medical clinic and recruited powerful doctors to come and treat patients. Yun Ruoyue would also personally lead apprentices and recruit medical students, hoping to train more doctors.
In the past three years, the two of them have been busy almost every day. Although they are busy, they have lived a fulfilling life.
Seeing that South Vietnam is now very prosperous, the people live and work in peace and contentment, and their lives are getting better and better, they both feel that no matter how hard they work, it is worth it.
Because it has always been the couple's wish to make people live a better life.
—
At noon that day, when Chu Xuanchen was reviewing official documents in his study, he suddenly heard a loud "bang" coming from Yun Ruoyue's laboratory next door.
"Yue'er!"
Hearing the loud noise, Chu Xuanchen was shocked and ran towards the laboratory next door.
As soon as he ran to the door of the laboratory, he saw a burst of thick smoke coming out of it, and Yun Ruoyue was lying on the ground in discomfort.
"Yue'er, what's wrong with you?"
Chu Xuanchen quickly ran over and hugged Yun Ruoyue in his arms.
Only then did he realize that Yun Ruoyue's head and face were stained with a lot of black ash.
He was so anxious that his pupils were wide open and his heart almost broke.
Seeing this, Yun Ruoyue hurriedly wiped the black ash on her face and said, "Xuanchen, don't worry, I'm fine, I'm just doing an experiment."
"Experiment?
What experiment to do?
Also, are you really okay?"
As Chu Xuanchen said, he carefully checked Yun Ruoyue and found that except for a lot of black dust on her body, she was indeed uninjured.
At this moment, his heart dropped to the ground.
"I'm really fine. When there was an explosion here just now, I fell down early, so I'm fine."
Yun Ruoyue said, looking at the billowing smoke in front of her, she said excitedly, "Xuanchen, let me tell you good news. I finally made gunpowder."
"gunpowder?
What is this?"
Chu Xuanchen asked doubtfully.
"Come here and take a look. These black powdery things are gunpowder."
Yun Ruoyue said, pulling Chu Xuanchen to a table.
As soon as Chu Xuanchen walked over, he found several transparent tubes standing there.
There were a lot of black powdery things inside those tubes, and he couldn't help but say, "Yue'er, is this the gunpowder you were talking about?
What’s the difference between it and firecrackers?”
"They are very different.
Firecrackers are relatively weak, but this kind of gunpowder can make many powerful firearms.
For example, it can be made into cannonballs, artillery, rockets, thunder cannons, thunderbolts, poison smoke balls, etc.
The power of these firearms is very great. With them, we can easily defeat the enemy in war."
Yun Ruoyue said confidently.
These are made through modern technology, combined with sulfur, nitrate, carbon, etc. This is real gunpowder, and of course it is very powerful.
"real?
Is this gunpowder so powerful?"
Chu Xuanchen held Yun Ruoyue's shoulders with a look of excitement on his face.
Yun Ruoyue nodded, "Yes, in fact, gunpowder was widely used in our era, because with it, we can win every battle.
Xuan Chen, I will make a few sky-shaking thunders right away, and then you can come with me to see how powerful they are."
