After Zhang Zuolin gained a firm foothold in the Northeast, Tan Sitong and Dai Xiaohou also made a breakthrough in the research and development of new tanks. In the Old Summer Palace in early summer, the ginkgo trees have been dressed in a layer of "green", and the leaves are shining in the sun. Although many congressmen did not understand why five million dollars were allocated to develop a new type of tank, Song Xiaofei secretly established his own "tank industry" in the Old Summer Palace with far-sighted spirit.

Dai Xiaohou took more than a dozen technicians in dark blue uniforms, accompanied Song Xiaofei and Tan Sitong to a brand-new "Dragon II" tank, and pointed to the camouflage tank with five load-bearing wheels to explain its parameters in detail: "The armor on the head and sides of the hull is thick, the turret is streamlined, and it has good bullet resistance. The tank is 9 meters long, 3.27 meters wide and 2.4 meters high, with a total combat weight of 36 tons and a crew of 4 people. The tank uses a V-shaped 2-cylinder water-cooled diesel engine with a rated power of 220 horsepower, a rated speed of 500r/min, a maximum speed of 20 km/h, and a maximum range of 400 miles. The main armament is a 70 mm rifled gun, 2 7.62 mm parallel machine guns, and 1 12.7 mm anti-aircraft machine gun. ”

The performance of this tank is a bit close to China's first generation of 59 tanks, Song Xiaofei, who was born as an artilleryman, once drove this kind of tank eliminated from the army during the exercise training, but in 1900, this performance of the tank is simply invincible in the world, Song Xiaofei is still satisfied with this tank, nodded, and asked: "How many tanks have been produced so far?" ”

Dai Xiaohou replied: "Two, this one is a command-type tank." At the suggestion of the President, the outer armor was made of this four-color solid-edged camouflage, a combination of four irregular color patches: yellow, gray, dark brown and green. and camouflage camouflage, formed by the connection of black borders. In this way, driving in the forest can be camouflaged. We've also redesigned the breech to fire high muzzle velocity shells, and now the gun can fire blunt-nosed armor-piercing and grenades. ”

Song Xiaofei asked, "What is the maximum rate of fire?" ”

Dai Xiaohou said: "Seven shells per minute. ”

Song Xiaofei personally went into the tank to take a look. Dai Xiaohou: The implementation of their idea is very good, this new type of tank auxiliary weapons has an anti-aircraft machine gun mounted on the top of the turret, a parallel machine gun mounted on the right side of the artillery coaxially, and a front machine gun mounted in front of the driver's right side. 4 viewing glasses are installed around the door of the commander's control tower; In front of the conning tower was mounted 1 commander's command sight glass. There is a periscope for the loader to observe in front of the loader door on the right side of the turret and a periscope for the gun commander to observe in front of the left side of the turret. In addition, a fence-type shield was installed on the turret, and composite armor was added to the nose and front of the turret.

Song Xiaofei personally test-drove the tank and roared a thousand meters away. It feels good. Dai Xiaohou came over and introduced that in addition to the simple manufacturing, stable performance, and easy maintenance and replacement of this tank, the number of track shoes can also be increased or decreased according to the training situation and wartime conditions. In ice and snow warfare, two steel spur track shoes can be replaced; In urban wartime, two hanging rubber track shoes can be replaced, "President, do you think there is anything else to improve?" ”

Song Xiaofei put forward a few suggestions for improvement based on his experience and memory in his previous life, "It is best to add anti-slip tracks to the tank tracks." Before the tank travels on snow or ice. In order to prevent slipping, the occupants need to disassemble the tracks, then install them on the other side, and finally combine the tracks. Adjusting the tracks is a chore, and the four crew members are busy for an hour or two, and they are so tired that they are sweating profusely, and it is estimated that they can be replaced. If you go to fight in the cold regions of Russia such as Siberia. Even worse, you can add a storage box behind the exhaust pipe on the left wing to store the non-slip tracks, which can be directly attached to the tracks when needed. In this way, it will be convenient to conduct operations in the northeast region and in the alpine plateau region. ”

When Dai Xiaohou heard this, this was another genius idea, and the president was an out-and-out military expert, and he was even more impressed, and repeatedly said that he would immediately organize back to organize engineering and technical personnel to improve.

Song Xiaofei said: "By the way, for non-command tank tanks, it is also necessary to install a camouflage antenna at the rear of the top deck of the turret to make it difficult for the enemy to distinguish between the battle tank and the command tank, otherwise it is easy to expose the commander's target." In addition, the safety door was changed to a three-point support type circular door that opened outward, and the current safety door had to open four handles and pull inward, and the gun had to turn an angle to get out of the car, which was inconvenient. It was necessary to change to three handles and push them outward, so that the crew could quickly drill out no matter what angle the gun was at. In combat, we must be people-oriented, and it is not easy to train a tank soldier, and it is better to lose a tank than to die a tank soldier. ”

Dai Xiaohou said: "Understood. Before this year's National Day, I will definitely complete the production of a hundred new tanks. The President is also asked to name our new tanks. ”

Song Xiaofei thought for a while, "My mentor Li Hongzhang once gave me the inscription 'Dragon Stings the World', it is called the 'Tianlong' tank, I hope this tank can soar the world!" ”

On September 28, 1900, at the National Day military parade of the Republic, President Song Xiaofei and members of Congress held a military parade on the city tower. Tan Sitong commanded a tank corps of 100 "Tianlong" tanks to slowly drive in front of the Forbidden City, the scene was spectacular, this improved armored tank, the overall performance of the main battle tank in the early stage of World War II is basically the same. Behind was the 100,000 army commanded by Duan Qirui, the army was neat, and the crowd in the square let out a warm and sustained cheer.

In October of the same year, four 10,000-ton Chinese warships "Beijing", "Gonghe", "Democracy" and "Science" were successfully launched at the Jiangnan Shipyard in Shanghai. Song Xiaofei received a telegram from Tan Sitong and was not surprised by the news. In the impression of many Chinese, the foreign affairs movement was a failure, and New China did not until November 27, 1958, when Dalian Shipyard built China's first 10,000-ton ocean-going cargo ship "Yuejin". Historically, the Jiangnan Shipyard in Shanghai accepted orders from the United States from 1918 to 1919 to build four 10,000-ton freighters of the same type, all of which were fully covered deck and steam-type cargo ships, named "Mandarin", "Celestial", "Oriental" (AL), and "Cathey" (CATHEY). The ship is 135 meters long, 16.7 meters wide and 11.6 meters deep, with a displacement of 14,750 tons. The first of these, the "Guanfu", was launched on June 3, 1920, and the four ships were accepted by the US Department of Transportation, and the engineering was solid and well-configured, and the US government was very satisfied with the quality of the construction of the four 10,000-ton ships.

In order to build these four giant warships, Xi Zhengfu also called on the industrial and commercial circles in Shanghai to donate, raised three times, and raised 10 million silver dollars for the warships, and all provinces across the country also donated. These four battleships were the most advanced ocean-going ironclad battleships in the world at that time, which were of epoch-making significance, and their status was equivalent to that of today's aircraft carriers.

These four warships are the same type of ironclad warships as the "Dreadnought" battleship designed and produced by the British Army in 1906, adopting the design concept of "all-heavy artillery", using 10 12-inch caliber main guns of a unified model with consistent ballistic performance, 5 twin main gun turrets, one at the bow and one at the stern, and one behind the boiler room of the amidships, arranged on the center line of the hull; Between the two boiler rooms, one on each side of the two sides is symmetrically arranged, and the maximum firepower of the ship's side is 8 main guns, and the forward fire is theoretically 6 main guns, and the firepower advantage is doubled.

The secondary guns of the warships only kept guns of caliber less than 3 inches, which were used to defend against small torpedo ships. For the first time, a warship uses four steam turbine units on a large warship, and while the maximum speed is increased to 21 knots, it can maintain high-speed navigation for a long time and maintain good reliability, which is faster than the 7,000-ton warships such as the "Dingyuan" ship.

Moreover, what is even more rare is that the defensive armor of these four warships is not inferior to any previous warship, the armor is treated with surface hardening, and the thickness of the armor in important parts reaches 11 inches, providing comprehensive protection capabilities.

With these four 10,000-ton warships, Song Xiaofei expanded China's navy to 12,000 people, even with the old naval power Britain. When the long whistle sounded, Song Xiaofei rode on the "Beijing" with a displacement of 130 million tons, he stood on the deck, looking at the row of brand-new guns on the warship, as well as the white waves rolling on the Huangpu River behind the warship, and the other three giant ships accompanying him, Song Xiaofei knew in his heart that the time for the Chinese people to raise their eyebrows and exhale was coming, and he decided to launch a war against Tsarist Russia in 1901, taking advantage of the fact that the Trans-Siberian Railway of Tsarist Russia had not yet been built, and to recover the 1.5 million square kilometers of land occupied by Russia. Song Xiaofei knew that after this battle, China would be able to raise its eyebrows in the world, and moreover, it would re-participate in the division of the world's colonies and complete the primitive capital accumulation for China.

At this time, one person actually jumped out to openly oppose it, he was Li Jingfang, the secretary general of the presidential office, and behind him, there were many conservative forces of the Huai Army who supported him.
