After He Yunfei and Su Yi discussed the formation of 200 new temporary infantry divisions and 40 new garrison independent infantry brigades of the Royal Army of the Tang Empire, He Yunfei took his leave and left.

However, just as He Yunfei had just left the Hall of Virtue, a mechanical voice suddenly sounded in Su Yi's mind, "Host, the experience points you have accumulated have reached five million, which meets the update requirements of the Overlord Rise system, may I ask if the host is updated?" ”

Su Yi couldn't help but be stunned for a moment, and then asked the system with his consciousness: "What does system update mean?" What will change after the update? ”

"Host, the system update costs five million experience points, and after the update, some new features will appear."

Su Yi couldn't help but feel a little distressed when he heard that he would consume five million experience points, knowing that once the experience points accumulated to seven and a half million, Su Yi's rank in the system would be upgraded by one level, and every time the rank was raised, there would be a very generous reward.

Su Yi hesitated and asked, "After the update, what new functions will appear in the system?" The original functionality isn't going away, is it? ”

"Please check the newly added features by yourself after the system update, and please rest assured that the original functions will not disappear after the update."

When Su Yi heard this, he shook his head helplessly, considering that the original function of the system would not disappear, in the end Su Yi agreed to consume five million experience points and let the system be updated.

Almost in the blink of an eye, Su Yi noticed that the data listed by the system in his mind had changed.

Host: Su Yi.

Military rank: Lieutenant Colonel.

Experience: 302/7500000.

Funding: 999999...... trillion yuan (RMB).

Mall: British Nelson-class battleships (unit price of 1.2 billion yuan, limited to four per year) (upgradeable+).

U.S. Colorado-class battleships (unit price 1.1 billion yuan, limited to four per year) (upgradeable+).

……

Warehouses: rice (260 million tons in existence), flour (240 million tons in existence), ......

System Mission: Unified Global (no time limit, no mission failure penalty, quest reward 18 Diamond Chests).

Su Yi found that this system update, in addition to an extra system task that is difficult to complete, is only behind some products in the mall, the three words upgradeable appear, and there is a red plus sign behind the three words upgradeable.

Su Yi immediately asked the system with his consciousness: "What does it mean to be upgradeable?" ”

"Host, click on the red plus sign behind the upgradeable product, there is a chance that the same type of product with more advanced performance can replace the original product, such as a former dreadnought battleship in the mall, after clicking upgrade, there is a chance to upgrade to a dreadnought battleship or a super dreadnought battleship."

Su Yi's eyes lit up, and he immediately took a closer look at the various goods in the mall, and found that most of the goods such as warships, warplanes, tanks, and guns were marked with the words "upgradeable" at the back, while behind the goods such as rice, flour, and gasoline, there were no words that could be upgraded.

Su Yi is thinking that the performance of the Renault FT-17 light tank and the 2C heavy tank in the system is too backward, and now with this commodity upgrade function, Su Yi can upgrade these two backward tanks.

However, Su Yi didn't upgrade the two tanks right away, and Su Yi asked the system, "What does chance mean?" Will the upgrade still fail? What happens if the upgrade fails? ”

"Host, every product upgrade has a 50% chance of success, if the upgrade fails, the product will completely disappear in the mall."

Su Yi suddenly gasped, with this restriction, then the upgrade of goods must be cautious, there are many goods, Su Yi does not dare to upgrade at all, for example, you can buy 6.8 million Mauser 98k rifles every month, once the upgrade fails, the Mauser 98k rifle disappears from the system mall, and Su Yi has no place to cry.

Su Yi looked at the various goods in the mall again, and then his eyes flashed, and he directly clicked on the red plus sign behind the Renault FT-17 light tank with his consciousness.

Immediately, a smile of surprise appeared on Su Yi's face, the Renault FT-17 light tank had disappeared from the system mall, and was replaced by another tank.

British Matilda 2 tank (unit price 1.8 million yuan, limited to 800 units per year) (upgradeable+).

The Matilda 2 tank, an infantry tank used by the British during World War II, weighed 26.9 tons, had a maximum speed of 24 kilometers per hour, a crew of 4 people, and was equipped with a 52 times caliber 40 mm gun with 93 rounds of ammunition, a 7.92 mm caliber machine gun with 2925 rounds of ammunition, and the thickness of the armor in the main part was 75 to 78 mm, and the secondary part was 25 to 55 mm.

Although the Matilda 2 tank was not an excellent tank during World War II in the original time and space, it could play a considerable role in the hands of the Royal Army of the Tang Empire.

Su Yi then clicked on the red plus sign behind the 2C heavy tank with his consciousness, but after the 2C heavy tank disappeared from the system mall, no new tank appeared, and it was obvious that this upgrade failed.

Su Yi saw the red plus sign behind the Matilda 2 tank, smiled wryly and shook his head, he didn't dare to continue to upgrade the Matilda 2 tank, the price of failure to upgrade was too great.

Of course, there is a gain, the new Matilda 2 tank, the annual purchase limit of 800 units, turned out to be a recalculation, so Su Yi immediately purchased 800 Matilda 2 tanks from the system mall.

Next, Su Yi looked at the four former dreadnought battleships in the system mall, and couldn't help but think of upgrading.

After the Royal Navy of the Tang Empire and the Royal Navy of the Purple Moon Empire possessed many super dreadnought battleships, Su Yi had already begun to consider deploying many of the former dreadnought battleships in the main fleets of the two navies to each garrison fleet.

Su Yi rubbed his hands and directly clicked on the red plus sign behind the Edward VII-class dreadnought battleship with his consciousness, which made Su Yi grin, this upgrade was not successful, and the Edward VII-class dreadnought battleship also disappeared from the system mall.

Su Yi then took a deep breath, and then used his consciousness to click on the red plus sign behind the Brunswick-class dreadnought-class, this time it was finally upgraded, after the Brunswick-class dreadnought battleship disappeared, a new battleship appeared in the system mall, the French Brittany-class battleship (unit price is 900 million yuan, limited to four per year) (can be upgraded +).

The French Brittany-class battleships, belonging to the category of super dreadnought, have a standard displacement of 23,230 tons, a full load displacement of 27,340 tons, a maximum speed of 20 knots, and are equipped with five twin 45 times caliber 340 mm guns, twenty-two 138 mm secondary guns, four 47 mm anti-aircraft guns, four 450 mm torpedo tubes, 262 mm main armor on the side belt, 25 mm deck armor, 254 mm main turret armor, and a crew of 1,130 people.

This is really a fight to turn a bicycle into a motorcycle, the former dreadnought battleship suddenly became a super dreadnought battleship, although the Brittany-class is among a large number of super dreadnought battleships, and the comprehensive performance is very average, but after all, it is a super dreadnought battleship, Su Yi's face suddenly showed a smile.

Next, Su Yi upgraded the Lord Nelson-class dreadnought battleship and the Connecticut-class dreadnought-class dreadnought, but what made Su Yi depressed was that these two dreadnought battleships all failed to upgrade.

In this way, it was equivalent to exchanging four former dreadnought battleships for a super dreadnought battleship, and Su Yi felt as if he had suffered a little loss.

"Doesn't that say that upgrades have a 50 percent chance of success? Why did only one of the four former dreadnought battleships succeed in upgrading? ”

"Host, the fifty percent chance of success is only relative, if the host continues to upgrade four more former dreadnought battleships, it may get three upgrade successes."

Su Yi listened to the system's words, pondered for a while, and felt that if he upgraded another warship, the chance of success was very high, Su Yi immediately gritted his teeth, and clicked on the red plus sign behind the large armored cruiser of the Minotaur class with his consciousness.

"Yay! And it worked! Su Yi couldn't help but shout excitedly.

German Moltke-class battlecruisers (unit price of 800 million yuan, limited to 24 units per year) (upgradeable+).

The Moltke-class battle cruiser, with a standard displacement of 22,979 tons, a full load displacement of 25,400 tons, a maximum speed of 25.5 knots, was equipped with five twin 50-caliber 280 mm guns, twelve 150 mm secondary guns, twelve 88 mm high-level dual-purpose guns, four 500 mm torpedo tubes, 270 mm of main armor on the side of the gun, 65 mm of deck armor, 250 mm of main turret armor, and a crew of 1,350 people.

The main guns of the Moltke-class battlecruisers, although only 280 mm in caliber, were not weak.

Historically, the main guns of the Moltke-class battlecruisers, in terms of number and power, were enough to offset the difference in caliber with the main guns of the early British battlecruisers, and could pose a mortal threat to the fragile defensive armor of the British counterpart.

In any case, even if the Moltke-class battlecruisers were a little weaker than the others, this upgrade was a big profit.

After successfully upgrading the Minotaur-class large armored cruiser, Su Yi did not resist the temptation of turning a bicycle into a motorcycle, and gritted his teeth and upgraded the Scharnhorst-class large armored cruiser, but unfortunately it was not successfully upgraded.

Without doing anything, Su Yi upgraded the last large armored cruiser in the system mall, the Blucher-class, and what Su Yi couldn't accept was that the upgrade of the Blucher-class large armored cruiser also failed.

Su Yi couldn't help but complain with a sad face: "Where is there a fifty percent chance of success, four former dreadnought battleships and three large armored cruisers, there are only two successful upgrades, and this success probability is too low!" ”
