After the Seven Nations Alliance officially declared war with the Tang Empire and the Purple Moon Empire, the Tang Empire and the Purple Moon Empire quickly converted 600 reserve infantry divisions into provisional infantry divisions, and armed almost half of the provisional infantry divisions according to the standard armament of the field infantry divisions of the royal armies of the two countries.

According to the number of army weapons that Su Yi can buy every month, as well as the current output of many arsenals of the Tang Empire and the Purple Moon Empire, there will be about four more months, and the weapons and equipment of the other half of the provisional infantry divisions can also reach the standard configuration of the field infantry divisions of the royal armies of the two countries.

While converting the 600 reserve infantry divisions into provisional infantry divisions, Su Yi demanded that every village, township, and city in the 64 provinces of the Tang Empire and the 33 provinces of the Purple Moon Empire should form militia units, and that young men between the ages of 18 and 35 of the Tang Empire and the Purple Moon Empire, if they have no physical disabilities, must join the militia units in various places, receive military training, and become reserve soldiers of the royal armies of the two countries.

In this way, the Royal Army of the Tang Empire and the Royal Army of the Purple Moon Empire, in addition to having more than 70 million troops, will also have about 400 million supplementary troops, Su Yi believes that just fighting for consumption is enough to drag down the Seven Nations Alliance, of course, Su Yi, who has the system, has not yet fallen to the point of fighting for his life with the Seven Nations Alliance.

After declaring war on the Tang Empire and the Purple Moon Empire, the seven countries of Yingluopa, Sharad, Noomi, Monia, Gisk, Ruierland, and Orenza also began to expand their armies on a larger scale, and the Noomi Empire, which has a population of 1.3 billion, announced that it would use reservists to form 37 new infantry regiments in one go, bringing the size of the Royal Army Infantry Corps to 70, and more than doubling the total strength of the Noomi Royal Army.

With a population of 500 million, the Royal Army originally had 18 infantry regiments and 12 independent infantry divisions, with a total strength of 6 million.

Before the declaration of war, the Salad Empire had already expanded by 40 infantry divisions, and after the declaration of war, the Royal Sharad Army announced the establishment of another 60 new infantry divisions, increasing the number of infantry divisions of the Royal Sharad Army to 180, with a total strength of 18 million.

The entire Sharad Empire was divided into the Western Theater by the Seven-Nation Alliance, and the armies of the Yingroba Empire and the Noomi Empire were all under the Western Theater, so soon after the declaration of war, the Noomi Royal Army first sent ten infantry regiments to the territory of the Sharad Empire, and then the British Roba Royal Army also had five infantry regiments began to be transferred to the territory of the Sharad Empire.

Su Yi has learned that the Seven Nations Alliance has divided the army into three theaters, of which the Western Theater will be the strongest theater of the Seven Nations Alliance, after all, the armies of the three kingdoms of Noomi, Sharad and Yingluoba were originally ranked in the top three of the world's armies, but Su Yi ignored the actions of the armies of these three countries for the time being, and instead focused on the Liuyun Empire and the Purple Moon Empire.

Although the two sides declared war a little earlier than Su Yi expected, Su Yi did not change the battle plan of the Convection Cloud Empire and the Celestial Star Empire to strike first.

At eight o'clock in the morning of October 3, 3013 in the Tang calendar, Su Yi brazenly ordered the Royal Army of the Tang Empire and the Royal Army of the Purple Moon Empire to attack the Liuyun Empire and the Celestial Star Empire respectively in the name of rescuing the Liuyun Empire and the Celestial Star Empire, which were enslaved by the Sharad Empire and the Jisk Empire.

At this time, in the border area adjacent to the Tang Empire and the Liuyun Empire, the Royal Army of the Tang Empire had gathered thirty field infantry divisions and thirty temporary infantry divisions as attack troops.

In the border area adjacent to the Purple Moon Empire and the Celestial Star Empire, the Royal Army of the Purple Moon Empire also concentrated thirty field infantry divisions and twenty temporary infantry divisions as attack troops, and divided their troops into the territory of the Celestial Star Empire.

At around three o'clock in the afternoon of October 3, in a large hall in the imperial palace of Liuyun City, the capital of the Liuyun Empire, Emperor Li Hong shouted to Prime Minister Cao Ziliang with an angry face: "Su Yi is simply too deceitful! In vain, Fei Zhen had the intention of uniting with the Tang Dynasty and Ziyue before, but he didn't expect Su Yi to send troops to our Liuyun Empire without any scruples! ”

Prime Minister Cao Ziliang said with a wry smile: "Your Majesty, it's too late to say anything else, and now that the front line is tight, let's hurry up and ask for help from the Sharad Empire!" In addition, the minister felt that since Su Yi didn't take into account the friendship of the same Tang country, then there was no need for our Liuyun Empire to save face, and we should join the Seven Nations Alliance as soon as possible, maybe after the war, our Liuyun Empire could still get some benefits. ”

Thanks to the support of the Sharad Empire's funds and weapons, the Liuyun Empire currently has more than 15 million land forces, of which the Royal Army of the Liuyun Empire is about 8.5 million, and the combined armies of the nobles of the Liuyun Empire are about 6.5 million.

In order to guard against the Tang Empire, the Liuyun Empire deployed more than nine million land forces in the border areas adjacent to the Tang Empire alone, with the Royal Army of the Liuyun Empire accounting for about five and a half million, and the other three and a half million belonging to the armies of various nobles.

Facing the Royal Army of the Tang Empire, whose weapons and equipment were several levels higher than their own, the top leaders of the Liuyun Empire knew in their hearts that even if more than nine million troops were deployed in the border area, it would be very difficult to block the attack of the Royal Army of the Tang Empire.

However, what is unexpected is that as soon as the troops of the Royal Army of the Tang Empire entered the territory of the Liuyun Empire, there were countless Royal Army and various noble armies of the Liuyun Empire, and they chose to surrender to the Royal Army of the Tang Empire without even firing a shot.

There were even a number of low-level young officers of the Royal Army of the Liuyun Empire, who directly led the troops to control the corps headquarters of the infantry corps, the division headquarters of each subordinate infantry division, and the wing headquarters of each infantry wing, and then announced the farce of the entire infantry corps battlefield uprising, but what makes people speechless is that most of these battlefield uprisings have been successful.

In less than eight hours after the start of the war, there were already three fully formed Liuyun Empire Royal Army Infantry Corps, and a full-fledged infantry corps under the command of a hereditary duke of the Liuyun Empire, in the above way, to complete the battlefield uprising, plus other Liuyun Empire Army that voluntarily surrendered or revolted to the Royal Army of the Tang Empire, so that just after the war, the Royal Army of the Tang Empire captured many border fortresses of the Liuyun Empire without blood, and received more than 2.5 million officers and soldiers of the Liuyun Empire who rebelled or surrendered voluntarily.

And some of the Liuyun Imperial Army that chose to resist also quickly collapsed under the unusually fierce offensive of the Royal Army of the Tang Empire, and in less than eight hours after the start of the battle, the Liuyun Imperial Army that was eliminated, captured and defeated by the Royal Army of the Tang Empire also had to be more than two million, so it can be said that the defense carefully arranged by the Liuyun Empire in the border area has been completely collapsed.

Because of the Liuyun Empire's Army, the four infantry divisions deployed by the Sharad Royal Army on the border of the Liuyun Empire were surrounded by the Royal Army of the Tang Empire.

Emperor Li Hong of the Liuyun Empire pondered for a moment and said to Prime Minister Cao Ziliang: "Immediately ask for help from the Sharad Empire, and also express to the Seven Nations Alliance that our Liuyun Empire is also willing to join this alliance against the Tang Empire and the Purple Moon Empire." ”

Then Emperor Li Hong turned his head to Yan Song, the Minister of War, and asked in a deep voice, "Should your War Department give me an explanation?" Why is it that less than a day after the start of the war, our Royal Army of the Liuyun Empire has so many troops and has taken the initiative to surrender to the army of the Tang Empire? How did you become a Minister of War! ”

Yan Song, who had just served as the Minister of War of the Liuyun Empire for a short time, looked helpless at this time, "Your Majesty, the minister is also very shocked now, according to the news from the front, many of the surrendered troops are some young officers from the wing headquarters, division headquarters and even the regiment headquarters, and they directly launched a mutiny, so that the entire wing, the entire division, and the entire legion of the Royal Army of the Liuyun Empire surrendered to the army of the Tang Empire without resistance, and the minister has strictly ordered all senior officers to strengthen the guards around them, Prevent this from happening again. ”

When Emperor Li Hong heard this, he suddenly said with some discouragement: "It seems that many people in the Royal Army have been bought by the Tang Empire, I wonder if our Liuyun Empire can survive the arrival of reinforcements from the Sharad Empire and other countries of the Seven Nations Alliance?" ”

Emperor Song Xuan, the Emperor of the Celestial Star Empire, who was connected to the Emperor of the Liuyun Empire Li Hong, was also troubled by the fact that a large number of Celestial Star Empire Army troops took the initiative to surrender to the Purple Moon Empire's Royal Army at this time.

However, the Jisk Empire has deployed more than 2.5 million land forces on the border of the Celestial Star Empire, so the border defense line of the Celestial Star Empire has not completely collapsed like the Liuyun Empire.

In the Hall of Virtue in the Imperial Palace of Chang'an City, Su Yi said with a smile on his face, He Yunfei, the commander-in-chief of the Royal Army of the Tang Empire: "I didn't expect that the military intelligence bureaus of the two countries could make great contributions this time, in less than a day, more than 2.5 million people in the army deployed by the Liuyun Empire on the border chose to revolt on the battlefield or take the initiative to surrender to the Royal Army of the Tang Empire. The capture of the Royal Army of the Purple Moon and the Two Moons is a fantastic start, and I must reward the meritorious personnel of the military intelligence agencies of the two countries. ”

He Yunfei said with a smile: "In fact, thanks to Your Majesty's set of ethnic theories above the Tang Dynasty, the military intelligence bureaus of the two countries can persuade a large number of young officers to pledge their allegiance to Your Majesty among the troops of the Liuyun Empire and the Celestial Star Empire, otherwise your subordinates will not persuade Your Majesty to launch an attack on the Liuyun Empire and the Celestial Star Empire as soon as possible." ”
