Xiahou's fierce generals in the world will not be calculated, but the truth that the arrogant army will be defeated should be at this time.

Xiahoudun didn't know the depth of Kong Ming, only knew that Liu Bei had been defeated repeatedly, when Zhao Yun came to challenge, Xiahoudun fought with him for dozens of battles, Zhao Yun was defeated and left, and Xiahou believed it.

After walking for more than ten miles, Xiahou didn't want to chase it, Zhao Yun led troops to fight again, Xiahou was furious and rose up to pursue.

Han Hao and Xiahou Lan were afraid of an ambush, and Xiahou was superstitious about force, so he didn't listen, so he ignored it.

Walking into Bowang, Yu Ban discussed with Li Dian, saying that there are a lot of reeds and thatched here, and the mountains and forests on both sides.

It was not until this time that Xiahoudun woke up, but when he woke up, it was already too late, only to see the fire in front and back, the left and right fires, Xiahoudun's military horses were burned, trampled on each other, and there were many dead.

Xiahoudun wanted to lead the army out, but there was an ambush in all directions, and Zhao Yun in front came back, and the two sides fought, and the dead were not counted.

Xiahoudun ordered Xiahoulan and Han Hao to save the grain and grass, Zhang Fei was ambushed on the side, the two armies fought, and in the chaos, Zhang Fei met Xiahoulan and stabbed him under the horse after only a few combinations.

Han Hao saw that Xiahoulan was dead, so he pulled out his horse and left, and he couldn't care about any food and grass.

Li Dian and Yu Ban saw that the general trend had gone, and they met Guan Yuma quickly, killed Shuhe and led the remnants of the army away, Xiahoudun packed up the remnants of the army, and returned to Xuchang to receive the punishment.

Since then, Zhuge Liang has established his status as a military advisor, and Liu Bei's generals have all bowed to him.

In September, the Chenhe Chamber of Commerce recruited again.

Thousands of miles west of Jiangxia, in eastern India, a country called the Amir Empire, which had risen strongly and quietly before, caused a crisis in the old empire Kushan Empire.

The Amir Empire controls the eastern and southern regions of India, with a population of four or five million, originally this region, there was no strong kingdom, since more than ten years ago, there was a young man named Amir, there was a large tribe called Amir, this tribe from the original more than 1,000 people, slowly developed into a large tribe that controls tens of thousands of people, founded 12 years ago, named Amir.

King Amir, who controlled southern India five years ago and had a population of 500,000, made muskets five years ago and cannons four years ago, and now has conquered three-quarters of the Indian continent and borders the Kushan Empire.

Amir's actions are completely opposite to Yang Xi, he went to the goal of dominating the world from the beginning, he never used his energy on construction, only started from force, and now he has developed an army of more than 300,000, which is far more than the Kushan Empire in terms of the number of troops and equipment.

Amir plundered all his material, and he was ready to destroy Kushan, rule over its entire population, and plunder all its wealth.

The Kushan Empire, which stretched from present-day Tajikistan to the Caspian Sea, Afghanistan and the Indus Valley, reached its peak under the rule of Kasserga I and his successors, with a population of 5 million and more than 200,000 soldiers, and was considered one of the four great powers of Europe and Asia at that time, alongside the Han Dynasty, Rome and Anxi.

In 183~199, during the reign of Hubisega II of the Kushan Empire, the control of Central Asia weakened, Kangju and Dawan got rid of the fetters, and Khorasan and Khorezm also broke away from the Kushan rule.

The Kushan Empire had fallen by this time, and Amir felt that the time was ripe, so he stationed 300,000 troops to the east of the Indus River, and in September 202, prepared to march to the northwest.

In September 202, the Chenhe Chamber of Commerce organized a fleet again, led by Dong Cai five giant ships of the Yangtze River and fifty ships of the Chenhe River, and went to India along the road again.

Yang Xi also knows that there should be considerable changes in other places, and he can't do it behind closed doors.

Sent out Dong Cai, Yang Xi also began to analyze the current situation, Yuan Shao is dead, his words can't last for two years, Gongsun Du seems to be about to hang up, he died of illness, there is no way.

Yang Xi took out the map he had drawn and analyzed it slowly.

"Cao Cao occupies the Central Plains, the Yuan family occupies Hebei, and Gongsun occupies Liaodong, I can't interfere in these places, and Cao Cao can handle it. Xiliang is also temporarily stable now, and Liu Zhang and Zhang Lu are in Yizhou and Hanzhong, and it is not something I can interfere with. “

"Jiaozhou is now Sun Quan and Zhou Yu are developing very well, it is said that Zhou Yu is ready to go west and occupy the territory of other countries, and he has no room for development in the Han Dynasty, which is also a good thing, I will not destroy."

"At present, there are only two places, one is Xuzhou, and if you get Xuzhou, you can connect Qingzhou with the south, which is a good strategy, but in this way, Cao Cao will not do it again, after all, Xuzhou is his territory, and as soon as he turns his face, he will slow down the pace of Cao Cao's unification of the north. And the two of us are killing and killing is even more chaotic. ”

"There is only Jingzhou, Jingzhou must take it, and Liu Biao has provoked me many times. But you can't take it all, and you have to leave a middle ground with Cao Cao as a buffer. ”

In the end, Yang Xi's fingers stayed in the four counties of Changsha, Wuling, Guiyang, and Lingling.

"Then take here, Changsha County infiltration is enough, as long as Wuling is taken and the Yangtze River is blocked, all the roads from Liu Biao to Guiyang and Lingling in the south will be blocked, these two counties, whether I take them or not, they are all in the bag."

From this moment on, Yang Xi decided to switch from strategic defense to strategic offense, and the time for an official attack had come.

So, Yang Xi handed over the formula of gunpowder to Yang Xiao.

After entrusting Yang Xi to keep it secret, Yang Xi finally breathed a sigh of relief.

It's finally come to this point, and it's been so long.

The gunpowder that Yang Xi wants to make is not ancient black powder, and the power of ancient black powder is too poor.

Saltpeter accounts for 75 percent, sulfur 10 percent, and carbon 15 percent, which is the basic configuration of modern gunpowder. However, if it is simply mixed like this, it can only be a dynamite bag like Yamamoto, and the power will not be too great.

What Yang Xi wants to do is even more terrifying.

In 1550 AD, the French invented the wet method.

First, the ingredients are soaked in water and moistened, then mixed to make a large cake, which is broken after drying or air drying, and sieved through a fine sieve, the gunpowder powder will become small granules, and then it is packed in a large barrel and constantly stirred, grinding off the corners of the particles and adding graphite for polishing.

The gunpowder produced by this method forms a relatively stable structure between the molecules, which is not easy to decompose, and the combustion space between the particles is large, and it is easy to burn evenly.

Because of the manufacturing process, this is called real modern gunpowder. The ratio of 75:1:15 to the modern gunpowder formula was also established in the 19th century.

Yang Xi didn't know that he was making gunpowder at the moment, and the European side had been shelling for several years.

Not to mention the recent alpha, India is rich in products, but in Europe, saltpeter is not produced.

At this time, several bigwigs in Europe competed in the Roman Empire, and they still used the methods of their ancestors, because there was no natural nitrate, they used toilet nitrate in the toilet to make gunpowder.

The nitrogen acid in the compost of human and animal waste is combined with potassium through natural chemical reaction to form nitrate, which is naturally known by the special forces of various countries, and this is not advanced knowledge and has no technical content.

Yang Xi ordered Yang Xiao to secretly make gunpowder and artillery, and prepare to gather troops to march west in January 203.

So from 203 onwards, the foundation of feudalism will be officially bombarded by the artillery of capital.
