In the blink of an eye, it was the end of 1835, and Long Yufei appeared in this world for almost half a year. In the past six months, he has not only successfully integrated into this world, but also become the substantive leader of the Flying Fish Company, Luo Sangu is just a nominal ruler, in fact, all major matters are decided by Long Yufei. The senior management of the Flying Fish Company also seemed to acquiesce to this situation, Long Yufei had proved his ability with his performance, and was recognized by many pirates on Flying Fish Island. After all, when they came and went in the wind and rain at sea, they never imagined that there would be such a day.

Now the Flying Fish company is growing rapidly every day. Almost every day, there are Chinese villages that are taking refuge in the Flying Fish Company, and these Chinese villages have as few as two or three hundred people and as many as thousands of people, which makes the population of Flying Fish City rise all the time. The entire Flying Fish City has also become a busy construction site completely, and the progress of the city's construction, which was originally a little slow, has been significantly improved after a large number of laborers have joined. Perhaps in a few months, a majestic city will appear in northern Mindanao.

The plains outside the city of Flying Fish City have also reclaimed a lot of fertile land. Mindanao's hot climate is ideal for growing rice and other food crops, and even though it's winter in China, grain can still be grown here. As the population of Flying Fish City grew, so did the need for more and more land. Fortunately, there are plains outside Flying Fish City, and enough fertile land can be reclaimed.

The company's steel plant and non-ferrous metal smelter have also expanded, and are now able to produce hundreds of tons of steel and wrought iron per month, and the output of copper has also increased to about 20 tons, so that the supply of ammunition to the Flying Fish army is no longer restricted. The molybdenum ore, chrome ore and nickel ore that Long Yufei has been looking for have also been found and have begun to mine. Soon, the service life of the barrels of the rifles used by the Exocet will be much improved. The most important thing is that the cannon steel used in the production of cannons has also been lost!

The arsenal of the Flying Fish Company has now increased the daily production of Flying Fish rifles to 50 rifles, and the ammunition has also increased to 10,000 rounds, which is enough to ensure the training and combat consumption of the Flying Fish Army. It's just that at the request of Long Yufei, Zhao Xingkai, the director of the arsenal, continues to expand production capacity. As the scope of the Exocet Army's control becomes wider and wider, and more and more armies are formed, the demand for weapons and ammunition will also increase.

Long Yufei is now very busy every day, developing steam engines with the blacksmiths of the Flying Fish Company every morning. The Flying Fish Company does not have professional technicians, so it can only rely on these craftsmen. After all, Long Yufei is very proficient in mechanics, otherwise relying on these blacksmiths alone, it would be more difficult to build a steam engine than ascending to the sky. In the afternoon, Long Yufei and Zhao Yi and his son developed new weapons. The Exoces do not yet have artillery to support infantry combat, which limits the Exocet's ability to attack fortifications. As the newly formed unit of the Flying Fish Army is about to complete its recruit training, Long Yufei is also eager to equip the Flying Fish Army with artillery as soon as possible, so that the Flying Fish Army can be engaged in the attack on the natives of Mindanao as soon as possible.

Mindanao's poor traffic conditions were not suitable for the use of heavy artillery. Therefore, Long Yufei's goal was to develop a mortar. The history of the development of mortars can be traced back to 1342 AD. At that time, the Spanish army was besieging the city of Alihquiras, which was occupied by the Arabs, and the Arabs erected short horn cylinders on the battlements, and the mouth of the cylinder was raised high towards the outside of the city. A packet of black powder was placed through the mouth of the barrel, and then an iron ball was put in, which ignited the twist and shot at the Spanish soldiers outside the city. This primitive artillery, known as "Modfa", can be said to be the prototype of the modern mortar.

The world's first real mortar was created during the Russo-Japanese War in 1904 and was invented by Russian artillery captain Leonid Nikolayevich Gobiato. At that time, Tsarist Russia and Japan were engaged in a fierce battle for the Port of Arthur in China. The Russian army occupied the fortress of Arthur Pass, and the Japanese dug trenches and approached only a few dozen meters away from the Russian position, and it was difficult for the Russian army to kill and injure the Japanese army with ordinary artillery and machine guns. So Nikolayevich tried to convert an old 47mm naval mortar gun on a gun carriage with wheels and fire a long-tail shell at a large elevation angle, which turned out to be effective in killing and wounding the Japanese troops in the trenches and repelling many Japanese attacks. This gun uses a long super-caliber **, with a total bullet mass of 11.5kg, a firing range of 50~400m, and a firing angle of 45°~65°. This kind of artillery, which was born in an emergency on the battlefield, was called "lightning cannon" at the time, and it was the earliest mortar in the world. However, the mortar invented by Gobiato was modified from a naval mortar gun, and although it had a short range, it could not be disassembled into portable parts, and it was still inconvenient for small infantry units to use in combat, so it was not widely used.

It was not until the First World War that due to the development of trench warfare, various countries began to attach importance to the role of mortars, and developed a variety of special mortars on the basis of "lightning artillery". Mortars were more widely used in World War II, and the armies of almost every country were equipped with this lightweight, suitable for infantry combat on a large scale.

The mortar mainly consisted of a gun body, gun carriage, bottom plate and sights, which were detachable, which made transportation more convenient on the march. The steel produced by the steel plant was not up to the requirements, which brought the development of the Exocet's artillery to a standstill. But with the advent of alloys with added metals like molybdenum, chromium and nickel, this has been solved that day. Relying on Long Yufei's advanced knowledge, the Flying Fish Army will soon be able to possess a lightweight mortar.

Long Yufei spends his time on scientific research every day, and other affairs of Feiyu Company are only handled at night. No company is developing rapidly, and there are many things that need to be dealt with every day, which makes Long Yufei often busy until late at night.

"It's not okay to go on like this, you have to find a way to share these affairs, otherwise, sooner or later, Lao Tzu will have to be exhausted to death!" After Long Yufei finished processing the last document, he stretched his waist.

"Yufei, it's a pity that I don't know anything, otherwise I would have been able to help you!" Luo Sangu said on the side. When Luo Sangu was young, she supported Flying Fish Island, and she was very bad at knowledge and needlework, and she felt a little uncomfortable watching Long Yufei busy so late every day.

"It's okay, Yuhua, your support is the greatest help to me!" Long Yufei held Luo Sangu's hand and said.

Luo Sangu struggled for a while, but did not break free, so she had to let Long Yufei hold it, but her expression was a little shy.

Looking at the female pirate leader who had been murderous and terrifying, he looked like a little daughter, Long Yufei was very satisfied, and couldn't help but move in his heart, and pulled Luo Sangu closer to his arms.

The climate in Mindanao is hot, and the clothes on both of them are very thin, so that they can clearly feel the temperature of each other's bodies.

Long Yufei is now 25 years old, and he was a technical master before, busy with his studies, and he didn't even touch a woman's hand, let alone go further. Now that a charming beauty is in his arms, where can he still hold it, he has already been in his heart.

In Long Yufei's office, there is a small bed for him to take a nap when he is tired, which comes in handy at this moment. Long Yufei picked up Luo Sangu and put her on the small bed, and the whole person was pressed up.

Luo Sangu's face was flushed at the moment, and her eyes were closed, like a lamb waiting to be slaughtered. Of course, with her force value, if she is unwilling, she can slap Long Yufei, a skilled artist, to fly away. It's just that she has already fallen in love with Long Yufei, and in the face of Long Yufei's presumptuousness, she did not resist, which made Long Yufei finally succeed!

The cot began to creak and sway, and two intertwined shadows appeared on the wall in the light of the oil lamp. The guards on duty outside the office were all driven away by Long Yufei's personal guard Li Hu.

After the clouds and rain stopped, Long Yufei hugged Luo Sangu and lay on the small bed, a pair of hands roaming on the smooth body, while Luo Sangu buried his head in Long Yufei's arms, not knowing how to face it.

"Yufei, do you think I'm a bad woman?" Luo Sangu said with some worry. After all, she had a relationship with Long Yufei before she got married, and she was afraid that Long Yufei would think that she was a bad woman with watery poplars.

"How can you think that? You are a good woman, and it is the greatest luck in my life that I, Long Yufei, can get you! Long Yufei said sincerely.

"But I don't know anything, I don't know how to be a needleworker, I can't take care of people!" Luo Sangu said in a low voice.

"None of this matters, as long as we are happy, that's enough!" Long Yufei said resolutely. As a modern person, he is not like many corrupt Confucians, who require women to be obedient and virtuous, and they are not allowed to show their heads.

Listening to Long Yufei's affectionate words, Luo Sangu finally put her mind at ease, she completely believed in Long Yufei's words, and her heart felt as if she had eaten honey.

"Yuhua, I've decided, I'm going to marry you! I'll go find Uncle Zhao tomorrow! Long Yufei said suddenly.

"Ahh Luo Sangu was a little surprised.

"What? Don't you want to? Long Yufei asked a little anxiously.

"No, of course I do!" Luo Sangu hurriedly said.

"Ha Lu Ha! That's it! I didn't expect that I, Long Yufei, would be able to get such a good wife! Long Yufei laughed.

Early the next morning, Long Yufei went to find Zhao Yi, he had no parents, and the same was true for Luo Sangu, so he could only ask Zhao Yi and Li Decheng and others for help in marriage matters!
