At 2 pm on December 18, 1907, the sky was dim and dim, and the foggy rain that made people feel bored fell from the sky one after another like fine needles.

On the coast of Yamaguchi Yoshi City, accompanied by Wang Songjiedi, the new naval commander of the Lanfang Republic, Chen Hao, Xia Xingyu, Lin Juemin and others walked to a shipyard near the school that had been built.

This shipyard is average in scale, but covers a very wide area. In addition to producing cargo ships and merchant ships of about 1,000 tons, it also produces assault boats and rubber boats for training for naval cadets, as well as fishing boats for offshore fishing and other ships.

Under the cover of this appearance, it is a submarine dock that penetrates deep under the mountain. This submarine dock built based on the huge mountain and uses the huge natural water holes under the mountain to open up and reinforce, which can accommodate four small submarines with a displacement of about 200 tons.

At the same time, two such secret submarine docks are also being built along the coastal areas under the rule of the People's Liberation Army.

While leading the way, Wang Songjie said to Chen Hao, Xia Xingyu and others: "Some Chinese ethnic groups in Indonesia have their own shipyards. When they heard that we needed their help from the shipyard, they couldn't wait to send the outstanding shipbuilding talents and skilled workers in their shipyards, greatly accelerating the construction process of our shipyard."

"Very good! Only by letting these Chinese people who are unwilling to succumb to the Dutch and Indonesians see hope can they spare no effort to support us." Chen Hao said with satisfaction.

"Yes! If the principal had not brought them hope, even if these people were patriotic, they would not have cooperated with us so actively." Wang Songjie said with deep emotion.

"Commander Wang, how many students have sent to the United States in total? How many students are there to prepare to go to train in the near future?" asked Chief of Staff Lin Juemin.

"General Lin, so far, the Naval School has recruited more than 7,000 students in three batches, and has sent more than 400 outstanding students with the fastest learning progress to go to the US Navy fleet for training. In addition, more than 500 outstanding naval students are going out to sea for internships. Two months later, the trainees who have passed the test will also set off for the United States." Wang Songjie replied confidently.

"Songjie, you have done a good job. I believe that under your leadership, we will soon be able to build a naval fleet that is much stronger than the Dutch." Chen Hao praised.

Wang Songjie said gratefully: "It is up to the principal's support and guidance that students can regain their vitality and engage in the great naval cause."

"Haha! The shipyard is here, take me to see Mr. Holan now!" When he arrived at the shipyard, Chen Hao couldn't wait to speak.

John Holland was born in Ireland in 1841. Holland was curious about oceans and warships since she was a child. Before she graduated from high school, Holland's father died of illness. The young Holland worked while designing submarines.

In 1875, Holland sent the plan to build a new submarine to the U.S. Navy, but was rejected by the U.S. Navy. Holland was not discouraged. He soon received strong support from the Irish revolutionary organization "Fennia Society" in exile in the United States.

With the support of the "Fennia Society", after several years of hard work, Holland built two submarines in succession. But just as Holland was investing in the manufacturing of his third submarine, the "Fennia Society" stopped funding for Holland.

Losing the funding of the Finnia Society, Holland cooperated with Zalinsky to build his fourth submarine, the Zalinsky.

Then, Holland received $150,000 from the U.S. Navy and began the design of his fifth submarine. He repeatedly studied and calculated the plans, and finally built his fifth submarine, the Diver.

The boat is 26 meters long and has a propulsion device for surface navigation and a propulsion device for underwater submarine submarine electric motor. The "Submer" has thus become the originator of the submarine dual-propulsion system.

However, for the need of war, the U.S. Admiralty required Holland to enable the Diver to be used for surface combat during the construction of the Diver. However, Holland believed that satisfactory submarines could not be made according to this requirement.

So Holland gave up the construction of the Diver, returned funds from the U.S. Navy, and began to use his own money to design and build a new submarine.

On May 17, 1897, Holland successfully built the "Holland-6" submarine. The boat was 15 meters long and equipped with a 33.1 kilowatt gasoline engine and a battery-powered electric motor. It is the latest submarine with dual propulsion.

When sailing on the water, the "Holan-6" submarine is powered by a gasoline engine, with a speed of 7 nautical miles per hour and a range of 1,000 nautical miles. When sailing underwater, it is powered by an electric motor, with a speed of 5 nautical miles per hour and a range of 50 nautical miles.

The submarine has a total of 5 crew members, and its weapons are a boat with three torpedo tubes at the fore and one gun in front and back. The gun aims at the target by controlling the submarine's body.

The use of the dual-propulsion system on the boat has made this submarine achieve unprecedented success in the history of submarine development, and its excellent performance has become the originator of modern submarines. Britain and Japan have purchased imitations one after another, and began the submarine era, thus establishing Holland's status as the "father of modern submarines".

The design of such a submarine is undoubtedly a genius design ahead of the times, but Holland's achievements did not bring him any benefits.

Due to the prejudice and pickiness of some U.S. Admiralty officials, the submarine was not only not adopted by the Admiralty, but instead caused the great inventor to be viciously ridiculed and attacked, and was given the titles of "scammer" and "idiot".

In 1904, the ruthless blow made Holland resign angrily. From then on, a generation of submarine master was forced to stop his beloved career, and he was worried all day long, and waited for death by drinking to relieve his sorrows.

However, by August 1907, Old Holland's fate began to change. Several mysterious English-speaking Chinese came to the door in the middle of the night and said they were willing to provide huge funds for him to continue developing submarines.

Although he had no good feelings for the Chinese, he could not develop his beloved submarine, which made Old Holland live like years and life was worse than death. With the mentality of seeking medical treatment in a hurry, Old Holland agreed.

So the mysterious Chinese leader immediately took out a check of $100,000 and gave it to Old Holland as a settlement fee, telling him not to tell anyone that after settling down his family, he would go with them to a paradise for developing submarines three days later.

After seeing the $100,000 settlement fee, Old Holland immediately believed the other party's sincerity. Three days later, John Holland, the "father of modern submarines", disappeared mysteriously in the United States.
