In a blink of an eye, it was the end of 1835. Long Yufei appeared in this world for almost half a year. In this six months, he not only successfully integrated into this world, but also became the substantial leader of Feiyu Company. Luo Sangu was just a nominal commander. In fact, all major events were decided by Long Yufei. The senior executives of Feiyu Company seemed to have agreed to this situation. Long Yufei had already proved his ability with his performance and was recognized by many pirates on Feiyu Island. After all, when they were in the wind and rain on the sea, they never thought that there would be such a day.

The Feiyu Company is growing rapidly every day. Almost every day, Chinese villages rely on Feiyu Company. These Chinese villages range from two to three hundred people and thousands of people, which has caused the population of Feiyu City to continue to rise. The entire Feiyu City has also become a busy construction site. The construction of the city, which was originally a little slow, has improved significantly after a large number of labor force joins. Perhaps in a few months, a towering city will appear in the northern part of Mindanao.

A lot of fertile fields have been reclaimed from the plains outside Feiyucheng City. The climate of Mindanao is hot and suitable for the growth of rice and other grain crops. Even though China is already in winter now, grain cultivation can still be carried out here. With the increasing population of Feiyucheng, the land needed is more and more. Fortunately, there are plains outside Feiyucheng, and enough fertile fields can be reclaimed from the outside.

Feiyu Company's steel plant and non-ferrous metal smelter have also expanded its scale. Now it can produce hundreds of tons of steel and iron every month, and the copper output has also increased to about twenty tons, which makes the supply of ammunition for Feiyu Army no longer restricted. The molybdenum, chromium ore and nickel ore that Long Yufei has been looking for has also been found and started to mine. Soon, the service life of the barrel of the rifle used by Feiyu Army will be greatly improved. Most importantly, the cannon steel used for the production of cannons will also be settled!

The arsenal of Feiyu Company now produces Flying Fish rifles every day to fifty and bullets have also increased to 10,000 rounds, which is enough to ensure the training and combat consumption of the Flying Fish Army. However, at the request of Long Yufei, Zhao Xingkai, the director of the arsenal, is still continuing to expand production capacity. As the Flying Fish Army's control scope becomes wider and more troops are formed, the demand for weapons and ammunition will become greater and greater. It is better to prepare early than to catch blindly in the future!

Long Yufei is very busy every day now, and he develops steam engines with the blacksmiths of Feiyu Company every morning. Feiyu Company does not have professional technicians, so he can only rely on these craftsmen. Long Yufei is very proficient in mechanics, otherwise it would be harder to build steam engines by relying solely on these blacksmiths. In the afternoon, Long Yufei and Zhao Yi and his son developed new weapons. The Feiyu Army has no artillery to support infantry combat, which limits the Feiyu Army's ability to attack. As the newly formed troops of the Feiyu Army are about to complete the training of the new recruits, Long Yufei also urgently hopes to equip the Feiyu Army with artillery as soon as possible, so that the Feiyu Army can join the attack on the indigenous peoples of Mindanao as soon as possible.

Mindanao has poor traffic conditions and is not suitable for the use of heavy artillery. Therefore, Long Yufei's goal is to develop mortars. The development history of mortars can be traced back to 1342 AD. At that time, Spanish troops besieged the city of Alihkilas, which was occupied by the Arabs. The Arabs set up short corner tubes on the battlements, and the mouths were raised high towards the outside of the city. A pack of black gunpowder was placed from the mouth of the barrel, and an iron ball was placed, which ignited the medicine and then shot at the Spanish soldiers outside the city. This primitive cannon, known as "Modefa", can be said to be the prototype of modern mortars.

The world's first real mortar was born during the Russo-Japanese War in 1904. The inventor was the Russian artillery captain Leonid Nikolayevich Gobiato. At that time, Tsarist Russia and Japan fought fiercely to compete for China's Lushunkou. The Russian army occupied the Lushunkou fortress. Japan dug trenches and approached only a few dozen meters from the Russian position. The Russian army could not kill and injure the Japanese army with ordinary artillery and machine guns. So Nikolayevich tried to modify an old 47mm naval mortar on a gun stand with wheels and fire a long-tail shell at a large elevation angle.

As a result, it effectively killed the Japanese army in the trench and repelled many attacks from the Japanese army. This gun used a long super caliber **, with a total ammunition mass of 11.5kg, a range of 50-400m, and a firing angle of 45°-65°. This artillery, which was born on the battlefield in an emergency, was called "lightning gun" at that time, and it was the earliest mortar in the world. However, the mortar invented by Gobiato was modified from a naval mortar. Although the range was short, it could not be disassembled into a portable component. It was still inconvenient for small infantry units to use, so it was not widely used.

Until World War I, due to the development of trench position warfare, countries began to pay attention to the role of mortars and developed a variety of special mortars based on "lightning guns". During World War II, mortars were used more widely, and almost all countries' armies were equipped with this lightweight artillery that was suitable for combating infantry on a large scale.

Mortars are mainly composed of gun body, gun stand, bottom sheet and sight, and can be detached, which makes transportation during the march more convenient. The steel produced by the steel mill before did not meet the requirements, which caused the development of the artillery of the Feiyu Army to stagnate. However, with the emergence of alloys such as molybdenum, chromium and nickel, I had already solved this day. Relying on Long Yufei's advanced knowledge, the Feiyu Army was able to have a lightweight mortar.

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

"It won't work if this continues. You have to find a way to share these affairs. Otherwise, I will be exhausted sooner or later!" Long Yufei stretched after processing the last document.

"Yufei, it's a pity that I can't do anything, otherwise I can help you!" Luo Sangu said from the side. When Luo Sangu was young, he supported Feiyu Island. He was very unfamiliar with knowledge and needlework. Seeing Long Yufei busy so late every day, she felt a little uncomfortable.

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

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

Looking at the female pirate leader who had killed people and was terrified, he looked like his little daughter, Long Yufei was very satisfied and couldn't help but feel moved, pulling Luo Sangu closer to his arms.

The climate in Mindanao is hot, and the clothes on both of them are very thin, which allows them to clearly feel the temperature of each other's body.

Long Yufei is now 25 years old. He was just a technical mate before. He was busy with his studies and had never touched a woman's hand, let alone further. Now a charming beauty is in her arms, and he can't control her. He has long been distracted.

There was a small bed in Long Yufei's office, which was used to take a nap when he was tired, and it came in handy at this moment. Long Yufei picked up Luo Sangu and put it on the small bed, and pressed him on.

Luo Sangu's face was flushed and her eyes were closed, like a lamb waiting to be slaughtered. Of course, with her martial arts value, if she was unwilling, she could slap Long Yufei, a technical mate. However, she had already been interested in Long Yufei, and did not resist in the face of Long Yufei's presumptuousness, which made Long Yufei finally succeed!

The bed began to sway, and under the illumination of the oil lamp, two tangled shadows appeared on the wall. All the guards on duty outside the office were driven away by Long Yufei's personal guard Li Hu.

After the clouds were closed and the rain stopped, Long Yufei hugged Luo Sangu and lay on the small bed, with his hands wandering 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 am a bad woman?" Luo Sangu said with some concern. After all, she had sex with Long Yufei before she got married. She was afraid that Long Yufei would think she was a bad woman with aphrodisiac.

"How could you think this way? You are a good woman. It is my 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 have a needleworker, nor can I take care of people!" Luo Sangu whispered.

"Nothing is important. As long as we are in love with each other, that's enough!" Long Yufei said firmly. As a modern person, he does not require women to obey and be virtuous, and not to show up in public.

After hearing Long Yufei's affectionate words, Luo Sangu finally felt relieved. She completely believed Long Yufei's words, and her heart felt as if she had eaten honey.

"Yuhua, I have decided that I want to marry you! I will go to Uncle Zhao and the others tomorrow!" Long Yufei said suddenly.

"Ah!" Luo Sangu was a little surprised.

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

"No, of course I am willing!" Luo Sangu said quickly.

"Haha! That's good! I didn't expect that Long Yufei, I, could have such a good wife!" Long Yufei laughed.

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