Before this personal expedition, Lin Yi led his guards to the southeast for more than 300 miles to Tianjin City.

The reason why he came to this city is because there is one thing he can't worry about before the prison conquest, and the second is because it has now become an important military base of the Ming Dynasty, and Tianjin here is also the area of Tianjin in later generations.

The city is now, that is, to the third year of Shunzhi, there are more than 200 years of history, this is still when Zhu Yuanzhang's fourth son Yan Wang Zhu Di launched the battle of Jingjing from here to cross the sea and land, from the hands of Emperor Jianwen after the capture of the country, Zhu Di ascended the throne for the Ming Dynasty, that is, the Yongle Emperor.

In order to commemorate this place, at the end of 1404, the second year after Zhu Di ascended the throne, he named this place Tianjin, which means the ferry port through which the Son of Heaven passed. From that time, the city began to be built, and Tianjin Wei was established, which became a military location, and later Tianjin Left Guard and Tianjin Right Guard were added.

Now Lin Yi has also taken a fancy to this piece of protected land, and used this area as a training base for sailors, and the specific location is in the vast sea area outside the Dagukou Fort, and Bohai Bay is the most suitable for training the navy, because the waters of this area are incomparable to the waters of the Yellow River and the Yangtze River.

And now that the Qing Dynasty has fallen, the dynasty has become a vassal state of the Ming Dynasty, this water area is super safe, training sailors in the sea, attacking and killing, and defending can definitely achieve the simulation effect.

Because now Lin Yi wants to set out to build a world-class navy, he can't just focus on the big rivers, and the sailors must adapt to the ability to fight in the sea, and even be able to carry out ocean navigation. Because Lin Yi's goal is very long-term, it is not just Zheng Zhilong's rebels, he has to deal with these maritime powers such as the Dutch Hongmaozi, at least to take back Taiwan.

He wants to prove to the world that his crossing not only brought the Ming Dynasty back to life, but what Emperor Kangxi could do in history, he Lin Yi can also do! The prosperous era of Kangqian was talked about by later generations, and he Lin Yi also wanted to create a peaceful and prosperous era, and the world was hot with this!

Therefore, he must start from the navy, which is the strategic vision of a Marine Corps special soldier who has crossed over from later generations. The current Daming Naval Division will definitely not be able to meet the needs, and in the six months since Lin Yi's class returned to Beijing, the plan to build a world-class navy has begun to be launched.

The first thing is to build a ship, and if you want to do a good job, you must first sharpen your tools.

The battleship built by Lin Yi this time is of course different from the previous warships, he plans to build a world-class giant battleship in a year, this giant battleship must be able to load a ton of red-coated cannons, and effectively cover a range of 10 miles.

Second, it must have a strong ability to sail against the wind and endurance, which means that the power must be sufficient. Therefore, the battleship had to be large enough.

Lin Yi is not wishful thinking at this point, because he knows that Daming's navigation ability has always been the world's leading, and navigation ability represents a country's naval strength.

Lin Yi had learned Zheng He's voyage to the Western Ocean before he traveled, that is, during the reign of Emperor Yongle, Eunuch Zheng had gone to the Western Ocean seven times, to the southeastern region, the magical country and the Cape of Good Hope, the Persian Gulf, etc.

It can be said that in the 15th and 16th centuries, China's navy was always world-class, but by the end of the Ming Dynasty, under the influence of natural and man-made disasters, this great empire gradually declined.

It was only then that Portugal, Spain, and later the Holland, the coachmen of the sea, and later the Hidden Kingdom, and so on, appeared as maritime overlords.

Now that the Netherlands has replaced Portugal and Spain as the sea lords, and his influence has extended to Taiwan, Lin Yi now has to reinvigorate his navy.

However, to build such a giant ship at sea, it requires a lot of manpower, material resources, and scientific and technological support, and it also requires a certain amount of time of training before it can become an army.

Therefore, after Lin Yi and the think-tank Song Xiance, as well as Gao Hongtu, Lu Daqi and other officials of the cabinet and the six ministries, the heavy responsibility of building the ship fell on the Nanjing officials.

Why Nanjing? It is self-evident that Nanjing has unique conditions, close to the great river, and since ancient times, the experience of shipbuilding and training sailors is unmatched by other places.

The technology, manpower, materials and silver required for shipbuilding in the Ming Dynasty are not a problem, and the technology of building large ships can be checked and skilled craftsmen can be found.

Now the money of the Ming Dynasty is not a problem, and now the Ming Dynasty is different from two years ago, and the court is rich!

Jiangnan was already rich, under Lin Yi's instructions, they increased their taxes in the past two years, and now the war in the Central Plains has subsided, and the people have resumed production, live and work in peace and contentment, and also have a part of the tax revenue.

In addition, a considerable amount of silver was obtained from the old bureaucrats of the Ming Dynasty, Li Zicheng of the Great Shun Army, and the Qing Dynasty, plus Lin Yiqian's savings and the income from the tributes paid by Mongolia and the dynasty, and now the pockets of the Ming Dynasty have swelled. Despite the continuous wars, the treasury revenue increased year after year, which was definitely a new atmosphere in the last years of the Ming Dynasty.

But despite this, Lin Yi still ordered to invite scientists and military experts from the Ming Dynasty, which are the famous Song Yingxing and Song Yingsheng and Tang Ruowang.

The Song brothers are famous, "Tiangong Kaiwu" is still a priceless treasure, but it is a pity that from Shenzong to Tianqi and then to Ming Sizong, these three generations of emperors and a group of ministers under them are illiterate, and the Song brothers have such a great ability to get a lifter, and then repeatedly went to Beijing to participate in the examination, and tried repeatedly, and then the two of them only became a five-grade and eight-grade petty official, and also worked as a teacher.

Finally boiled up to become a five-grade official, the war was still chaotic, and the people in the yamen ran out, and then they finally got tired of the officialdom and quit the official job, and the unhappiness of life was still written, which was called the 17th century craft encyclopedia.

Now that the Chongzhen Dynasty is over, the Ming Dynasty has ushered in the era of Lin Yi's imprisonment, of course, these two scientific giants cannot be buried, so Lin Yi issued an order to let Nanjing's military department Shangshu Shi Kefa, with Lin Yi's handwritten edict, personally go to Xinfeng, Zhejiang, the hometown of the Song brothers.

The Song brothers are both fifty or sixty-year-old men, and they thought about this life and died in obscurity.

I didn't expect the imperial court to still think about them, and crowned their brothers as the left and right attendants of Nanjing's military department, although Nanjing's two attendants as the accompanying capital are not the same as the military attendants of Yanjing, but from a common man who is idle at home to farm, to the soldier's waiter, it can be regarded as a step to the sky.

Therefore, when the Song brothers saw Lin Yi's handwritten message, they were so excited that they burst into tears, knelt on the ground, and bowed to Yanjing, grateful.

Then he immediately packed up his things and went back to Nanjing with Shi Kefa.

As for this Decheng missionary Tang Ruowang, Lin Linyi knows his value, he is not only a scientist, but also a world-famous military expert, who once cast dozens of cannons for Emperor Chongzhen.

A well-known scientist in this period of the Ming Dynasty, Lin Yi had learned it before the crossing, and Xu Guangqi couldn't find it, because he left this world before Lin Yi crossed, and he could only consult his famous works, like Song Yingxing, Song Yingsheng, Bi Maokang, Tang Ruowang, these Taishan Beidou-level figures in the scientific and military circles, of course Lin Yi can think of them.

Bi Lao has already given Lin Yi everything he has learned in his life, and the self-born flintlock pistol came out more than 100 years in advance, and the Song brothers also came, this Decheng guy Lin Yi ordered Jinyiwei to find it.

In the more than half a year since Lin Yi returned to Yanjing, of course, the factory guard has also been adjusted, the so-called son of heaven and a courtier, although Lin Yi has not yet ascended the throne and become the emperor, but this is a matter of time.

It turned out that Cao Huachun of the Admiral Dongchang and Wang Chengen, the eunuch of the Imperial Horse Supervisor, Gao Qiqian, etc., as well as some of the heads of Jinyiwei, as Li Zicheng led the Dashun army to attack Yanjing and Emperor Chongzhen hanged himself on the coal mountain, these people fled to death. In particular, Li Zicheng and his Dashun army were defeated by lightning and destroyed in the battle of Shanhaiguan by lightning, and the Ming Dynasty came back from the dead.

The original Dongchang and Jinyi guards, and heard that now the prince of the Ming Dynasty took the initiative to abdicate and let the prince and prince Lin Yi act as the supervisor of the country, and some people did not dare to stay in the factory guards, because they all knew that the factory guards had a holiday with Lin Yi, and Gao Qiqian took thousands of factory guards to eradicate Lin Yi, but they were all eradicated by Lin Yi, and hundreds of Jinyi guards were killed overnight, including two thousand households of Jinyi Guard.

Now they are not afraid that Lin Yi will settle accounts with them after the autumn, so these old factory guards have long since disappeared without a trace.

After Lin Yi returned to Yanjing, he still re-established Dongchang and Jinyiwei, these two spy agencies are unique characteristics of the Ming Dynasty, and they can add centralized rule, as long as they are properly managed, they will not cause any damage to the officials and the people, so they must not be abolished.

Now the eunuch of the Admiral Dongchang is Lu Jiude, and the commander of Jinyiwei is Ma Luan, the son of Ma Shiying, and the factory guard is temporarily in the hands of these two people, needless to say, the two of them are loyal to Daming and Lin Yi, which has been tested on the battlefield for a long time, so Lin Yi has long known it, and there is no need to doubt their loyalty at all.

The factory guard sent manpower, and the commander of the Jinyi guard made Ma Luan personally come forward, investigate and secretly visit, and finally found this Decheng guy Tang Ruowang, Lin Yi personally met him in Yanjing, promised to let him continue to preach in Daming, and built a church for him, but he must continue to study for Daming's firearms.

John Tang readily agreed, now that the Qing Dynasty has perished, he wants to preach here, and he has to continue to serve the Ming Dynasty, which he knows very well.

Lin Yi crowned him as the Guanglu doctor, and Song Yingxing, Song Yingsheng and Tang Ruowang formed the military expert group of the Ming Dynasty, with Song Yingxing in charge, and the first thing to do in Nanjing was to build this giant warship.

In this regard, after the officials in Nanjing received Lin Yi's will, Shi Kefa led the officials in Nanjing to go all out to support Song Yingxing and them in building ships in terms of manpower, material resources and financial resources.

Ship building and training sailors were carried out at the same time, and now Lin Yi has set a training base for a new sailor in the Ming Dynasty in Bohai Bay, that is, the vast sea area outside the mouth of Weidagu in Tianjin.

Accompanied by officials from the Yamen of the Tianjin 3rd Division, Lin Yi inspected the training of sailors.

At present, in addition to the 50,000 horses and horses under the command of the three dukes of Jiangyin along the Yangtze River, who are dealing with Zheng Zhilong's rebels, the naval division of the Ming Dynasty has now recruited a group of new soldiers with a total of 10,000 people, who are personally taught by generals who are familiar with water warfare from all over the country, and the training is in full swing.

Don't look at the number of 10,000 sailors, but in the future, Song Yingxing and a few of them will build a super giant ship, and the sailors they need will be selected from these 10,000 sailors.

10,000 will select 3,000 elites to go on the ship in the future, and this battleship can become the aircraft carrier of the Ming Dynasty after it is formed.

The remaining 7,000 sailors will be assigned to other large and small warships to form an ocean-going warship formation as the accompanying ships of the giant warships.

After inspecting the naval training base, Lin Yi returned to Beijing with his men.

Then he chose a good day and an auspicious day, and left Shangjing with a camel artillery team and an army of 100,000.

The generals who accompanied him this time included Zu Keyong, the chief general of the Beijing battalion and now the commander of the standard battalion, Dong Sheng, the commander of the invincible battalion, Wang Qi, the commander of the artillery battalion, Minmin Myrtle, the commander of the camel artillery team, Tie Shubuhua and Subutai, the commander of the Mongolian cavalry battalion, Zhang Hua of the guard battalion, and Xiao Ying, Zhezhe, and Su Moer of the women's battalion.

This team was supposed to go to Sichuan to fight, to clean up the remnants of Zhang Xianzhong, Sun Kewang and others, and to pacify the rebellion in Sichuan, Guizhou, and Yunnan.

However, the route of Lin Yi's march was not to go straight to the southwest from Beijing, but to go straight to Nanjing.

More than half a month later, the team drove to the vicinity of Nanjing. 100,000 horses set up camp outside the city.

Then Lin Yi took the soldiers of the guard battalion and the women's battalion into Beijing.

Outside Beijing, Shi Kefa took Nanjing's civil and military officials into the north bank of the river and picked up Lin Yi and others on the big boat.

It was the first time for Lin Yi to come to Nanjing, the capital of the Ming Dynasty, and it was indeed the land of the tiger. The rocks pierce the air, and the waves crash on the shore.

Lin Yi had no intention of watching the scenery here, what he was most concerned about now was, what was his warship built now?

After abandoning the ship and going ashore, under the guidance of Shi Kefa and others, Lin Yi rode his horse straight to the shipyard, a military stronghold. It's heavily guarded, and outsiders are not allowed to approach, let alone enter.

On the road from Nanjing to the shipyard, all the soldiers of the Ming army, five steps and one post, ten steps and one sentry, implemented traffic control, that is, all martial law.

The common people and those idle people and other unrelated people, either let them take a detour, or let them hide far away.

The official road was cleaned cleanly, Nanjing's Jinyi guards opened the way in front, followed by Lin Yi's guards and women's battalion, and Lin Yi rode a horse in the middle.

When they arrived at the gate of the shipyard, the welcoming soldiers were even more distinctly armored, and they were holding their own flintlock pistols in their hands, which looked neat and tidy.

In order to protect the shipyard, more than 5,000 elite soldiers lived here, that is, 5 thousand households.

At this time, Song Yingxing, Song Yingsheng and Tang Ruowang, accompanied by Wei Commander and other officials, also greeted them at the door, they were all brand new official uniforms, and after seeing Lin Yi's horse head, they quickly knelt on the ground.

Lin Yi asked them to be exempt, and when he looked carefully, Lin Yi found that Song Yingxing, Song Yingsheng and Tang Ruowang, the three of them had their own characteristics, and they all looked good.

After seeing the ceremony, like the stars holding the moon, Song Yingxing and others led the way in front, and Lin Yi entered the fully enclosed shipyard.

Song Yingxing first took out the drawings they had designed and presented them to Lin Yi, of course, these drawings were passed through the Ministry of War's cabinet supervisor and passed to Lin Yi's dragon book case.

This is Song Yingxing's record, in order to let you see it clearly, take out the drawings first. In fact, there is no need to look at the drawings, Lin Yi already has that map in his heart, he just wants to see where they have progressed.

Judging from the dimensions of the figure, the total length of this giant battleship is 150 meters, the width is 60 meters, the draft is 4.5 meters, the height of the ship is 4 floors, the carrying capacity is more than 2,000 tons, and it is not afraid of waves. Including the red-coated cannon thousand pound Franc machine, the ship is equipped with a total of 70 guns of various kinds, of which the most powerful red-coat cannon weighs more than one ton, such a gunboat is designed with a total of ten, followed by the thousand pound Franc machine, a total of 60 pieces, although the range of this kind of cannon is relatively close only one or two miles, but the rate of fire is fast, just complementary to the red-coat cannon to form a medium-range firepower strike, within one mile is the ship musket is responsible.

The ship has 10 masts and a sail angle of more than 70 degrees, which means that as long as there is wind, the ship can sail on the wind, both downwind and upwind.

If there is no wind, then it is powered by hundreds of sailors who step on water wheels, and even then, the speed is not slow.

Because after the completion of this giant battleship, it will be able to accommodate 3,000 officers and men, and there will be 500 sailors who are responsible for driving the ship alone, and 200 sailors on one side and 400 on both sides to add power to this giant ship.

When there is no wind available, they are in a fixed position like a water wheel, and through the action of pulley levers, they add driving force to the ship.

If this giant warship is completed, it will be much larger than the largest ship in Zheng He's fleet in the Western Ocean, and much larger than the most advanced cruiser of Britain and France 100 years later, with a much larger hull and tonnage.

Therefore, after the completion of this ship, it can definitely be called the overlord of the sea, and it is not an exaggeration to say that he is the aircraft carrier of the Ming Dynasty.

This drawing was Song Yingxing, Song Yingsheng and Tang Ruowang according to Lin Yi's several requirements, they checked the information, turned over the files, and it took more than a month to design it, and it was presented to Lin Yi two months ago, and Lin Yi immediately approved it.

But the drawings are easy to draw, and it is not easy to build such a giant battleship.

Lin Yi took the drawings and came to the dock workshop, where all the people who worked were soldiers, and countless soldiers and generals were busy here. The main outline of the ship has been revealed, but it will take at least 8 to 10 months to complete, according to Song Yingxing.

Lin Yi turned around and watched, while Song Yingxing, Song Yingsheng and Tang Ruowang explained to him, everywhere he went, Xiaoying and Zhezhe Su Mo'er and others also listened to it with relish, such a big battleship, they were simply unheard of.

After reading it, Lin Yi was generally satisfied, but also pointed out a lot of improvements to them. After all, before Lin Yi crossed, he was familiar with all these as special forces of the Marine Corps, aircraft, submarine aircraft carriers, cruisers, destroyers, and frigates.

The battleship built in front of him was nothing compared to the ships in the aircraft carrier formation that Lin Yi had seen before he crossed.

For Lin Yi's opinions and suggestions, they all carefully recorded them in detail, and finally Lin Yi rewarded them and lived here for three days.

During these three days, the three dukes of Jiangyin heard that Lin Yi was coming to Nanjing, and they hurried to Nanjing from the front line to meet Lin Yi, Bingchen and Zheng Zhilong's rebel battle situation, now both sides have their own victories and defeats, Lin Yi knows that Zheng Zhilong, Shi Lang, Liu Guozhuan These people are not easy to deal with, so let the three dukes of Jiangyin take the defense as the public, and do not underestimate the enemy's trade. After being able to hold out for a year, Lin Yi put down the rebellion in the southwest, and if Zheng Zhilong's rebels were still tossing at that time, Lin Yi would personally clean them up. After Yan Yingyuan and the other three led the troops, they left Nanjing and returned to the front line to continue the battle with the Zheng army.

Three days later, Lin Yi left Nanshan Beijing and took his 100,000 men and horses and began to march westward, straight into Sichuan.

To quell the war in the southwest, Lin Yi planned to complete it within a year, and then began to work on his world-class naval plan, including the defeat of the women's battalion into the Ming Marine Corps.
