Although the Parthian Empire had a standing army of only over two million, it had a very complete reserve system, which enabled it to expand its army to more than five million within a month.

Moreover, the newly expanded three million troops were basically soldiers who had undergone years of training, and their combat effectiveness was no worse than that of the officers and soldiers of the Parthian Empire's regular army.

If the Parthian Empire was given three months to complete the second wave of mobilization, its army could be expanded to 10 million.

Of course, the combat effectiveness of the five million troops expanded later was much weaker than that of the regular army, but these five million soldiers would enter the barracks for training for at least two months every year, and they could be considered qualified soldiers.

The reserve system of the Parthian Empire still has one final wave of mobilization, so all men aged 14 and above and under 65 in the Parthian Empire will be incorporated into the Parthian Empire's army.

The Parthian Empire was made to a point where every citizen was a soldier, and the number of its troops reached a terrifying number of over 25 million.

It is precisely because the Parthian Empire has such a complete reserve system that it has been able to suppress the Toulouse Empire with a population of 130 million and firmly control the Parthian Empire's territory in the western continent.

This time, after the Parthian Empire was invited by the Heavenly Church to join the Western Continent's Eastern Expedition, it immediately launched the first wave of mobilization of its reserve system, which increased the number of its troops to more than five million.

This also allowed Kuturuk, the king of Parthia, to dare to take out three million Parthian troops and incorporate them into the Heavenly Army of the Western Continent.

At the end of January in the 196th year of the Han calendar, the armies of the Western Continent countries that joined the Eastern Expedition, as well as the one million-strong Holy See Army of the Heavenly Church, arrived one after another at Yinhui City, a major city in the south of the Parthian Empire.

As a military fortress, Yinhui City is not very large, and even if it accommodates 100,000 troops, it will still seem extremely crowded.

It is impossible for the Western Continent's Eastern Expedition Army, with a strength of over ten million, to station all of them in Yinhui City. The armies of various countries could only build temporary camps with a radius of hundreds of miles outside Yinhui City.

As the host, Duke Elisil, the great general of Parthia, held a banquet in the Lord's Mansion of Yinhui City to welcome the generals of the armies of various countries.

Before the banquet began, Cardinal Kupriya of the Heavenly Church summoned the generals of the armies of various countries to hold a military meeting.

In fact, it is more accurate to say that it is a military meeting than a meeting among the countries participating in the Western Continent's Eastern Expedition to discuss how to divide the fruits of victory after the war.

"Everyone, according to the latest news, the Yanzi, Anlu, Wuli, Xiuye, and Moshan countries in the Western Regions have gathered more than four million troops, and the pagans of the Mosha religion have also organized an army of one million.

"But the greatest threat to our Eastern Expeditionary Force is the millions of Han troops led by the Han Emperor," Cardinal Kupriya said solemnly.

The status of the Purple Cardinal in the Heavenly Church is second only to the Pope. There are a total of seven Purple Cardinals in the entire Heavenly Church. Kupria is the youngest of them, only 42 years old this year.

As soon as Cardinal Kupriya finished speaking, Duke Leonor, the general leading the Apulian Empire, asked, "I wonder how many troops the Han Emperor brought with him this time?"

At this time, Duke Elisir, the great general of the Parthian Empire, spoke up, "News has come from the territory of Yanzi that the Emperor of Han has brought at least seven million troops with him, and over four million of them are barbarian cavalry from the grasslands north of Han."

Just after the New Year's Eve, Sun Hao led his army out of Anyang City and hurried to Xizhou.

In order to deal with the Eastern Expedition Army of the Western Continent, in addition to the 4.16 million nomadic cavalry of the Guiyi Army, Sun Hao also mobilized the First, Second, Third, Fourth, Ninth, Tenth, Eleventh and Twelfth Regiments of the Imperial Guards, a total of eight regiments of the Imperial Guards.

As well as the left and right guards and the front and back guards of the Imperial Guard, and ten garrisons.

The reason why there were 160,000 more Guiyi Army soldiers was that after Sun Hao readjusted the Imperial Guards, he added all the 40,000 Black Armor Cavalry, 40,000 Beiwei Cavalry, 40,000 Tiger and Leopard Cavalry and 40,000 Xiliang Iron Cavalry that were laid off into the Guiyi Army.

Together with the tens of thousands of centurions who originally served as officers in the four million Guiyi Army, there are now more than 200,000 centurions from the "annual signing system" among the more than four million Guiyi Army.

The 200,000 Great Snow Dragon Riders that were summoned by Sun Hao for the night attack on the 1.5 million Mengjie cavalry were all incorporated into the Royal Guards.

Currently, the left and right guards and the front and back guards of the Han Dynasty Royal Guards each have 100,000 Great Snow Dragon Riders under their command.

The Northern and Southern Guards of the Imperial Guards each had 50,000 Tiger Cavalry and 50,000 White Robe Cavalry under their command, while the Eastern and Western Guards each had 50,000 Modao soldiers and 50,000 White Robe soldiers under their command.

The missing 10,000 Tiger Cavalry, 10,000 White Robe Cavalry, 10,000 Mo Dao Men and 10,000 White Robe Soldiers were all exchanged by Sun Hao using the "Hero Converter" after he returned to Beijing.

Including the 160,000 Great Snow Dragon Riders from the First, Second, Third, and Fourth Towns of the Imperial Guards, Sun Hao brought a total of 560,000 Great Snow Dragon Riders with him on this expedition.

In addition, in the annual lottery of the 196th year of the Han calendar, Sun Hao's luck exploded and he signed out 300 million points of conversion value, which made the conversion value stored in the "Hero Converter" suddenly exceed 470 million points.

This also means that if Sun Hao needs it, he can exchange for more than 470,000 Great Snow Dragon Riders at any time.

With a million Snow Dragon Riders by his side, Sun Hao is confident that he can win even if the armies of the countries in the Western Continent gather tens of millions of troops.

In addition to signing out 300 million points of conversion value, Sun Hao also signed out eight powerful generals whose combat power values were all 100 points.
