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 everyone many modern production techniques, which has greatly improved the production efficiency of South Vietnam.
More and more Chu people are coming to South Vietnam, and everyone gathers here to build South Vietnam together.
When Yun Ruoyue and Chu Xuanchen help others, they do not give them food directly, but teach them to be self-reliant and let 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.
And the quality of these 50,000 Zhennan Army is not inferior to 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 quality 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 to conduct sea farming on the sea, which can increase fish production.
They also re-planned the city 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, suppressed bandits, developed agriculture and commerce, and slowly turned South Vietnam, a poor place, into a prosperous place.
Yun Ruoyue and Chu Xuanchen also built many charity halls to adopt homeless orphans.
The two of them also funded the construction of a medical clinic and recruited powerful doctors to come for consultation. Yun Ruoyue would also personally lead apprentices and recruit medical students, hoping to train more doctors.
Over 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 the 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 startled 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 hurried over and held Yun Ruoyue in his arms.
It was then that he discovered 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? Also, are you really okay?" Chu Xuanchen said, carefully checking Yun Ruoyue and found that except for a lot of black ash on her body, she was indeed uninjured.
This time, his heart fell to the ground.
"I'm really fine. When there was an explosion here, 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 some 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.
In those tubes, there were a lot of black powdery things. He couldn't help but said, "Yue'er, is this the gunpowder you are talking about? What is 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. These Firearms are very powerful. With them, we can easily defeat the enemy during a war." Yun Ruoyue said confidently.
These are the things she has learned through modern times? technology, combined with sulfur, nitrate, carbon, etc., this is real gunpowder, and of course it is very powerful.
"Really? This gunpowder is so powerful?" Chu Xuanchen held Yun Ruoyue's shoulders with 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. Xuanchen, I will make a few thunders right away. Then you can go with me Look at how powerful it is." (Remember this website address: www.hlnovel.com
