Su Yi did not go to Purple Moon City, but He Yunfei, the commander of the Su Army's army unit, personally rushed to Purple Moon City and commanded the three Guards Infantry Brigades, two field infantry brigades and two Marine Brigades of the Su Family Army to fight.

After sending the 1st Guards Infantry Brigade and the 2nd Guards Infantry Brigade, Su Yi soon sent the 3rd Guards Infantry Brigade, the 1st Field Infantry Brigade, the 2nd Field Infantry Brigade, the 1st Marine Corps and the 2nd Marine Corps, a total of five brigades, to Purple Moon City, making the strength of the Su family army in Purple Moon City reach 140,000.

As the Su family army entered Purple Moon City, Su Yi's experience value immediately began to soar, and in just a few days, Su Yi's rank in the system was promoted from lieutenant to captain.

What made Su Yi breathe a sigh of relief was that the experience value of being promoted from captain to major was not expanded ten times from the original basis, but only by five times, which means that as long as Su Yi accumulates another 500,000 experience, he can be promoted to the rank of major.

After Su Yi was promoted to captain, the number of weapons and ammunition equipped by the army in the system mall has been greatly increased again, with 7.92 mm bullets and 9 mm pistol bullets per month, and the monthly purchase limit has become 1 trillion rounds, and the monthly purchase limit of M24 grenades has become 100 billion.

The monthly purchase limit of 60mm mortar shells, 75mm field artillery shells, 105mm howitzer shells, and 155mm howitzer shells has also been greatly increased, which is enough for the artillery units of the Su family army to ignore the consumption of these four types of shells.

In addition, the monthly purchase limit of Mauser 98k rifles, MP34 submachine guns and Walther P38 pistols has become 1.2 million, and the monthly purchase limit of Mauser 98K sniper rifles and MG-42 general-purpose machine guns has become 40,000.

The monthly purchase limit of the M-2 mortar has become 8,000 units, the monthly purchase limit of the M1897 field artillery has become 4,000 units, the monthly purchase limit of the M2 105-mm howitzer has become 800 units, and the monthly purchase limit of the M1 155-mm howitzer has become 400 units.

As for the other goods in the mall, after Su Yi was promoted to captain, the number of purchase restrictions for several types has been greatly improved, the monthly purchase limit for rice has changed from 500,000 tons to 20 million tons, and the monthly purchase limit for four flavors of canned meat has become 10 billion cans.

The monthly limit on heavy oil and gasoline has become one billion barrels, and the monthly limit on anthracite has become one billion tons.

Su Yi felt that in the future, he only needed to rely on selling rice and canned meat, which was enough to pay tens of millions of troops, and selling anthracite, heavy oil and gasoline to foreign countries was also a good source of income.

After the promotion of the rank to captain, six products were added to the system shop.

World War II German Army combat uniforms and backpacks (unit price 2,000 yuan, monthly purchase limit of 100 million sets).

World War II German Navy combat uniforms and rucksacks (unit price 2,000 yuan, monthly purchase limit of 100 million sets).

WWII German SS combat uniforms and backpacks (unit price 2,000 yuan, monthly purchase limit of 100 million sets).

Compressed biscuits (unit price 10 yuan, monthly purchase limit of 10 billion packs).

Military tents (unit price 3,000 yuan, limited to 1 million per month).

Penicillin (unit price 2 yuan, monthly purchase limit of 1 billion pieces).

The three types of combat uniforms consist of two sets of military uniforms, winter and summer, as well as military caps, helmets, underwear, shoes, socks, and backpacks including bedding, raincoats, spare shoes and socks, sapper shovels, water bottles, and gas masks.

The combat uniforms of the biochemical people purchased from the system are exactly the same as the military uniforms of the Liuyun Imperial Army, but with the current situation of the Su Family's army, it is already a little inappropriate to continue to wear the military uniforms of the Liuyun Imperial Army.

Su Yi decided that the officers and men of the Guards would wear the combat uniforms of the German SS in World War II in the future, the officers and men of the field troops would wear the combat uniforms of the German Army in World War II, and the officers and men of the Independent Fleet would wear the combat uniforms of the German Navy in World War II.

The system then told Su Yi very intimately that the cyborgs purchased in the future would be equipped with a set of German SS combat uniforms and backpacks.

Each pack of compressed biscuits is only two hundred grams, and now that the Su family army has entered Purple Moon City, it is just right to send a batch of compressed biscuits to the front-line troops to solve the ration problem of the Su family's officers and soldiers during the battle.

The specifications of the military tents are 4.8 meters wide, 10 meters long, and 1.8 meters high, which can accommodate 20 officers and soldiers.

Penicillin is very effective in controlling wound infections, and penicillin has been developed in the world, but it is quite expensive.

Before coming to the Purple Moon Empire, the brigade headquarters of each brigade of the Su family army had a field hospital, and the doctors and nurses were recruited from Xingang City and Kangshan City.

The batch of penicillin purchased by Su Yi is much worse than the penicillin in the system mall, and the penicillin sold in the system mall is 1.6 million units, and the penicillin in this world is generally only 10,000 units.

The random reward for the promotion of the rank to the captain is still a diamond treasure chest, after this diamond treasure chest was opened by Su Yi, a total of seven cards appeared in the item warehouse, including a low-level amplification card.

U.S. Vickers-class destroyers (unit price of 20 million yuan, limited to 36 ships per year).

German Wiesbaden-class light cruiser (unit price 60 million yuan, limited to 12 units per year).

British Minotaur class armored cruiser (unit price 150 million yuan, limited to six per year).

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

Army-type mid-level combat biochemical personnel (unit price is 10 million yuan, limited to 180 people per year).

Navy-type mid-level combat biochemical personnel (unit price of 20 million yuan, limited to 180 people per year).

After the above four warship cards were added to the system mall, the number of Lion-class battlecruisers, Minotaur-class armored cruisers, Wiesbaden-class light cruisers, and Vickers-class destroyers that Su Yi could purchase every year was doubled.

As the scale of the Su family army grows larger and larger, the shortage of middle and senior officers is also getting bigger and bigger, and now there are one more than one hundred and eighty army-type mid-level combat biochemical people and one hundred and eighty navy-type intermediate combat biochemical personnel every year, so that Su Yi's arrangement of middle and senior officers does not have to be so stretched.

The low-level amplification card was used by Su Yi on the army-type primary combat biochemical person, and then the army-type primary combat biochemical person was changed from a monthly limit of 12,500 people to a monthly purchase limit of 25,000 people, which was only doubled.
