The rank in the system was promoted to lieutenant, and a diamond treasure chest was randomly rewarded, and after Su Yi clicked on it, a total of five cards appeared in the item warehouse.

American Vickers-class destroyers (unit price of 20 million yuan, limited to 18 ships per year).

German Wiesbaden-class light cruiser (unit price of 60 million yuan, limited to six per year).

British Lion-class battlecruiser (unit price 800 million yuan, limited to four per year).

Radio transmitter (unit price 5,000 yuan, monthly purchase limit of 2,000 units).

Spare barrels for 188 types of large-caliber naval guns (unit price of 200,000 yuan to 10 million yuan, and the purchase of one large-caliber naval gun per month is limited to 2,000).

The British Lion-class battlecruiser, with a standard displacement of 26,250 tons, a full load displacement of 29,680 tons, a maximum speed of 27.5 knots, was equipped with four twin 45-caliber 343 mm main guns, sixteen 102 mm secondary guns, four 533 mm torpedo tubes, 229 mm main armor on the side belts, 64 mm deck armor, 229 mm main turret armor, and a crew of 1,250 people.

Su Yi was very satisfied with the five cards from this diamond treasure chest, the first three cards could allow the independent fleet to immediately add four battle cruisers, six light cruisers, and eighteen destroyers.

In the future, the annual purchase limit of the US Vickers-class destroyers will become 36, and the annual purchase limit of the German Wiesbaden-class light cruisers will become 12.

The battle cruiser is a kind of capital ship with strong functionality that has evolved on the basis of the armored cruiser, and it is a battleship that combines powerful firepower and high mobility, which can not only effectively combat the enemy's attack, but also be able to quickly deploy to deal with emergencies.

At present, the radio transmitters equipped by the army units under Su Yi are all from the warships, and only a few are allocated to each infantry wing, and in the future, 2,000 radio transmitters can be purchased from the system mall every month, which can be regarded as a complete solution to the communication problem between the army units at all levels.

One hundred and eighty-eight large-caliber naval guns have a spare barrel, the smallest caliber has a spare barrel of 100 mm, and the largest caliber has a spare barrel of 530 mm.

For example, the 380 mm main gun of the Bavaria-class battleship has a service life, and the service life of the barrel is about 110 to 130 rounds.

Su Yi was still worried, in the future, if the main guns of the battleships of the Independent Fleet reached the service life, there would be no spare barrels in his hands to replace, and now the system helped Su Yi solve this thorny problem at once.

However, Su Yi was a little surprised to see a spare barrel with a caliber of 45 times 530 mm, as far as Su Yi knew, in the original world, the battleship with the largest caliber of main guns was the Yamato-class built by the Japanese Navy during World War II, but the main gun of the Yamato-class was only 460 mm, and the system made a 530 mm spare barrel, which was definitely not for no reason, maybe he could get a more powerful battleship than the Yamato-class from the system in the future.

Xu Haoming, the eldest son of Xu Ziliang, the county guard of Kangshan County, is indeed a talent in internal affairs, because of Xu Haoming's help, Kangshan City, which changed its owner, did not have any chaos, of course, the most important thing is that Su Yi took out 20,000 tons of rice and millions of canned meat, and sold them to the civilians of Kangshan City at a low price.

However, on April 20, 3011 in the Tang calendar, many civilians in Kangshan City panicked, and the two infantry divisions of the Jisk Empire arrived near Wandian Town, seven kilometers west of Kangshan City, on the morning of April 20.

In a private house in Wandian Town, Lu Sheng, the captain of the First Infantry Wing of the Xingang Garrison Force, said anxiously to Su Yi: "Marshal, the Jisk Empire has sent two infantry divisions this time, and Wandian Town will soon become a battlefield, so Dashuai should hurry up and return to Kangshan City!" Please rest assured, our 1st Infantry Wing and 3rd Infantry Wing are confident to hold Wandian Town, the only way to Kangshan City! ”

Su Yi sighed and said: "I'm also a little worried about coming, Wandian Town is a dangerous terrain here, easy to defend and difficult to attack, once Wandian Town is lost, there is no danger outside Kangshan City, and the two divisions of the Jisk Empire can drive straight in and directly attack Kangshan City, and Wandian Town is a little far from the sea, and you can't get naval artillery support." ”

At this time, Zhao Xin, the commander of the 3rd Infantry Wing, said: "Marshal, although we have not received artillery support from the navy, there are forty 105 mm howitzers and twenty 155 mm howitzers arranged here in Wandian Town, plus our two infantry wings have relatively complete fortifications and sufficient ammunition. ”

Zhao Xin is also an army-type mid-level combat biochemical.

Su Yi nodded and said: "In order not to cause chaos for you, then I will go back to Kangshan City, tomorrow your commander will be able to lead six wings to arrive at Kangshan Port, there are still two infantry wings in Kangshan City, which can support you at any time, and you must block the army of the Jisk Empire to the west of Wandian Town." ”

On a hillside about ten kilometers west of Wandian Town, Fei Duo, the commander of the 15th Division of the Gisk Empire, put down the telescope in his hand, and then said in a deep voice to Fimochika, the commander of the 26th Division of the Jisk Empire next to him: "The army of the Liuyun Empire has built a large number of fortifications in Wandian Town, and it seems that our two divisions, if they want to attack Kangshan City, we must first pull out the obstacle of Wandian Town." ”

The commander of the 26th Division, Fimochika, shrugged his shoulders and said: "Wandian Town is more than fifty kilometers away from the sea, which has exceeded the maximum range of the battleship's main guns, we attack Wandian Town, but we don't have to worry about being shelled by the battleships of the Liuyun Empire, with the strength of our two divisions, if there is no naval mess with the Liuyun Empire, it will not be a problem to take Wandian Town, after all, the troops of the Liuyun Empire landing in the Kangshan City area are only 20,000 or 30,000 people in total." ”

The commander of the 15th Division, Fei Duo, sighed at this time and said: "I am not worried about attacking Wandian Town, but once we attack Kangshan City, it is inevitable that we will be shelled by the naval warships of the Liuyun Empire, and even the coastal defense artillery of Kangshan Port will also attack our two divisions, and it is definitely a very difficult thing to capture Kangshan City, and the losses of our two divisions will definitely be very large." ”

The commander of the 26th Division, Fimochika, said with a wry smile: "I originally thought that with the presence of our Royal Navy of the Gisk Empire, it would not be such a difficult task to capture Kangshan City and Kangshan Port, but I didn't expect that a hereditary baron of the Liuyun Empire would have six super dreadnought battleships and four dreadnought battleships, and also defeated the two main fleets of the Royal Navy, and now our two divisions can only fight hard!" ”
