There is a third reason, which is what Kangju King Alan once said, he once pursued Ma Chao's wife, Princess Suguang of Wusun, and another suitor at that time was the prince of Guishan.

So based on the above three reasons, Bo Tiao hated Ma Chao to death, and Han Sui's daughter cried in her ear.

At that time, the king of Kushan was seriously ill and could not manage the government, in fact, Bo Tiao was in charge of the country as the crown prince.

Therefore, he vigorously rejected public opinion and instructed the ministers of his faction to support his decision to declare war on the Han Dynasty.

He sent an envoy to the Protector of the Western Regions stationed in Shule City, and submitted a declaration of war, saying that he would retaliate for Ma Chao killing the border guards and violating the sovereignty of Guishan.

Of course, Fa Zheng can't blame Ma Chao, Ma Chao himself has done nothing wrong, although he is a little reckless when he crosses the border to chase and kill.

However, the Kushan Empire favored Han Sui's bandits first, and with the iron-blooded spirit of the Han and the Central Army, they were replaced by other commanders, even if Fa Zheng or Lu Bu were present, they would make the same decision as Ma Chao.

The top priority at the moment is to be well prepared for battle.

Fa Zheng has worked hard in the Western Regions and Central Asia in the past few years, and he still knows this Kushan Empire very well.

This behemoth declared war with the Han Dynasty, and took advantage of the time and place, and this war was not very easy to fight.

Therefore, he sent a letter to Lü Bu asking for help, and in the letter, he detailed some common knowledge of the Kushan Empire to help Lü Bu mentally prepare for the difficulty of this war.

The Kushan Empire was established by the Kushan Marquis Department, one of the five great marquis of the Dayue clan.

The Yueshi people were originally nomadic in the area from Zhangye to Dunhuang in the Hexi Corridor, and they were powerful and one of the strong enemies of the Huns.

During the Western Han Dynasty, Zhang Qian once sent an envoy to the Dayue clan and wanted to contact them to attack the Xiongnu together.

Later, the Dayue clan formed a grudge with Wusun and killed the king of Wusun, and the descendants of the king of Wusun defeated the Dayue clan with the help of the power of the Xiongnu.

The Otsuki clan moved westward to the Amu Darya River valley in Central Asia, where they gradually became stronger.

The first conquered Bactria and was also called Bactria, all of which were descendants of the Greeks.

Then gradually conquered Khorezm, Kangju, Dawan, Khorasan, and ruled the entire Amu Darya and Syr Darya Darya.

It is divided into five major tribes, also known as the Five Great Princes.

During the Eastern Han Dynasty, the Marquis of Kushan rose to power, unified the five major tribes, established the Kushan Empire, and went south to conquer the Kabul River valley and Kashmir.

Later generations of kings actively expanded their territory to the west and south.

At its peak, the empire stretched from Patna in the east, to Herats in the west, to the Nabada River in the south, and to the Aral Sea in the north.

Today, the rule of the Kushan Empire is declining, Kangju and Dawan are out of its control, and Khorezm, Khorasan, and the Western Governorate are also on the verge of leaving.

However, even so, the population of the Kushan Empire still exceeded seven million people, and the imperial army numbered in the hundreds of thousands.

Moreover, the Kushan Empire integrated ancient Greek culture, Oriental culture, and ancient Indian culture, and the science and technology were still relatively developed, the metal manufacturing industry was also relatively advanced, and the weapon manufacturing technology was very mature.

The imperial army was dominated by cavalry, with both the infantry of ancient Greece and the infantry of ancient India.

The most disadvantageous factor of the Han fighting with it is the long distance, and it is difficult to mobilize the army and supply materials.

Although Kangju is an ally, Dawan and Wusu in the Western Regions can also provide some troops, materials and food, but it is mainly up to the Han government to solve the problem.

Not surprisingly, the question of the war in Central Asia was again debated in the court of Chang'an.

There are many opponents, basically civilian officials oppose the war, and military generals are the main battle.

The arguments of the opponents are still the clichés of reckless military force, labor and money, financial constraints, and supply difficulties.

But this time it was the Kushan Empire that took the initiative to declare war, not counting the Central Army's good at fighting, people are going to hit the door, and the Central Army can't be a turtle with a shrunken head!

Besides, the battle of Jingzhou has just ended, and the country is temporarily peaceful, and Cao Cao and Sun Quan are greatly damaged this time.

It's too late to consolidate their newly acquired territory in Jingzhou, where is the ability to start a civil war?

After the recovery of Jizhou and Qingzhou, the Yellow River valley was basically unified, peaceful, the people were stable, and production and life returned to normal order.

In addition, the Chang'an imperial court overhauled roads and built water conservancy facilities within its own control, and its ability to resist disasters was significantly enhanced.

The entire central government's jurisdiction is characterized by good weather and good harvests, prosperous trade, and a full flow of business and travel.

The central government's fiscal revenue has increased greatly, and in the words of the frustrated minister, it can support Lu Bu to fight hard.

That's why Lu Bu ignored the noisy objections, and stepped up preparations for the war.

He inspected the industrial base in the Guanzhong area, and in order to step up the production of urgently needed weapons and equipment, the three major military industrial bases under the Central Military Industry Department, the Guanzhong Industrial Zone, the Jinyang Industrial Zone in Bingzhou, and the Jimo Industrial Zone in Qingzhou, all started working overtime at full capacity.

Horse-drawn carts and transport ships carrying equipment and supplies to Chang'an every day are endless.

The new helmets need to be replaced, at least all participating troops must be given priority to do so.

Mortars in artillery battalions should also be reequipped, and mortar shells and grenades should be increased in ammunition reserves.

The front-loading smoothbore flintlock pistol had been finalized and began mass production, but due to the constraints of the responsible process and rudimentary means of production, the production capacity was limited, and only one brigade of the special operations division was reequipped.

This brigade is the brigade that has participated in the trial now, it is the first special operations brigade of Wenpin, oh, Wenpin has been promoted to brigade commander, and Huo Jun has also been promoted to division commander.

The brigade eliminated the spearmen and crossbowmen, retained only the hoplites, and the spearmen and crossbowmen all became musketeers.

The original marksmen were all equipped with front-loading rifled guns specially prepared for them, and became the sniper that Lu Bu dreamed of.

The firing range of ordinary smoothbore guns is only 100 to 120 zhang, but the range of rifled guns is as high as 400 zhang, which is farther than mortars, but unfortunately there is no scope.

Lü Bu signed a military order, and Fa Zheng served as the supreme commander of the Central Army in the war against the Kushan Empire, with full command of all participating troops.

In addition to the 6th Division, which was originally stationed in Kangju, the 3rd Cavalry Division stationed in Dawan, and the 7th Cavalry Division stationed in Wusun, Chang'an will send a large number of reinforcements.

Tai Shici's 9th Division, Cao Xing's 5th Cavalry Division, and Huo Jun's 6th Cavalry Division will take turns after the end of the war, but they will first have to fight together.

A number of other units were to go to Central Asia, each with artillery battalions and grenades.

With such a huge amount of demand, all military factories are producing at full capacity.

Because many factories should still be called handicraft workshops, they are in the stage of manual manufacturing, so they need a lot of manpower.
