In the spring of the grassland, strong winds are everywhere, sand and stones are flying, and the sun and moon are dim.

A convoy of several miles, traveling on the line from Dongsheng to the Yellow River, was as small as a boat in a storm.

More than 2,000 fully armed soldiers were mixed in the convoy and divided the convoy into five sections, so that they could quickly organize defense when attacked.

Zheng Jiadong was riding a tall horse, surrounded by more than a hundred elite guards, and was excited to listen to a military and political officer bragging and spanking.

"...The three legions such as Xiongwei, Shenji, and Pili were stationed in Jiangnan. They had no wars for more than a year, and were nicknamed the "Yards Runners' Legion" by the soldiers..."

Zheng Jiadong was obviously attracted by the "Yard Runners' Legion" and asked in confusion: "The Southeast Army, which is famous all over the world, is actually called the "Yard Runners' Legion"?"

The military and political officer laughed and said, "There is no war, and the public order is maintained every day. The 'Yards Runners' is well deserved!"

Zheng Jiadong thought about it, found it interesting, and asked with a smile: "The Three Southeast Army is called the Yashang Army. What is the Tiance Army stationed in Jingzhou?"

The military and political officer put away his jokes and replied seriously: "Of course it is the 'Tongle Legion'!"

Zheng Jiadong was amused by the free expression of military and political officials and laughed out loud, saying, "I understand this, I will join the people all day long and engage in some military and civilian affairs!"

"That's right!" The military and political officer smiled again, and then said, "It's better for my Wuwei Army Corps. Although it was established late, I grabbed a good place on the Nine Borders. The soldiers' military achievements and ranks rose up, making the Tiger Roaring Legion drooled in envy!"

...

This military and political officer naturally came from the Wuwei Army and was responsible for the central contact between the Wuwei Army and Zheng Jiadong's troops.

At first, Zhang Fengyi led the Wuwei Army and cooperated with Zheng Jiadong's troops to advance north. Zhang Fengyi handed over the heavy responsibility of protecting the food road and transporting the baggage to Zheng Jiadong's troops. Zheng Jiadong originally wanted to lead his troops to fight with the Mongols in a dark and unparalleled career, but his command was full of infantry and he didn't even have the qualification to eat sand after following the Mongolian horses. He had to accept Zhang Fengyi's arrangement and provoke the heavy responsibility of transporting the baggage.

Seeing that Zheng Jiadong's army was extremely short of cavalry and was worried that it would be a big deal when escorting food and grass, Zhang Fengyi sent a sentry cavalry to hand it over to Zheng Jiadong and carried out the reconnaissance responsibility.

This military and political officer is under the cavalry sentry, and his rank is only Renyong Wei. Renyong Wei had no right to march on horseback, but when Zheng Jiadong saw that this military and political officer was funny and knowledgeable, he equipped the military and political officer with a war horse and walked with his bridles every day.

A strong wind hit, and the convoy of several miles was immediately wrapped in yellow sand, which seemed to be shady, which made Zheng Jiadong look back and forth involuntarily and sighed: "From Dongsheng to Lucheng (now Baotou), it is two hundred miles long, and it is windy and sandy. Fortunately, there is a hard road, which leads straight from Dongsheng to Lucheng, so there is no need to worry about getting lost. This road is strangely straight and strangely hard. When did anyone build such a road?"

The military and political officer replied: "This road is the 'Qin Road', which leads from Xianyang to Lucheng. It opens the mountains and opens the road and builds bridges, and never turns."

"Qin straight road?" Zheng Jiadong was shocked and said, "Is it built by Qin Shihuang thousands of years ago? Leading to Lucheng, Qin Shihuang built the road to Lucheng thousands of years ago?"

The military and political officials nodded and said, "It was exactly what Qin Shihuang built! During the Warring States Period, King Wuling of Zhao attacked the Xiongnu in the north, established Jiuyuan County in Lucheng, and built the Great Wall in Yinshan to resist the Xiongnu going south. Later, the Xiongnu took advantage of the Qin State's busy unification of the country and had no time to look north, so he took the opportunity to go south and headed straight to Yulin. After Qin Shihuang unified China, he sent general Meng Tian to attack the Xiongnu in the north, established Jiuyuan County in Lucheng, and ordered Meng Tian to supervise Qin Zhidao and expand his power to the foot of Yinshan."

Zheng Jiadong was stunned and said for a long time, and sighed: "During the Qin Dynasty, the Han people were so powerful that it was really unimaginable. Later, although the Han and Tang dynasties were at the peak of the Central Plains, their power was difficult to expand to the foot of Yinshan Mountain. It can be seen that one generation was worse than the other! Alas..."

When the military and political officials saw Zheng Jiadong depressed, they smiled and retorted: "General Zheng does not have to belittle himself. Regarding the difficulty of expanding his power to Yinshan in the Han and Tang dynasties, there is an article in Xingzhi Journal specifically analyzing the reasons, which is quite interesting."

"oh?"

The military and political officer pointed to the stirrup under Zheng Jiadong's feet and asked, "Can General Zheng know when the stirrup appears?"

"Stackup? Isn't this thing available since ancient times? Who knows when it will appear?" Zheng Jiadong asked in confusion.

"According to the professors in Xingzhishu Hall, stirrups appeared when the Qin and Han dynasties alternated! That is to say, when Meng Tian attacked the Huns in the north, the Huns had not yet equipped stirrups and were just lying on the horses!"

Zheng Jiadong was shocked and asked in a daze: "How is this possible? Without stirrups, how to shoot arrows and chop?"

The military and political officer smiled and said, "No? Therefore, Meng Tian led the infantry and carried a crossbow machine to easily drive the Huns out of Yinshan. When Emperor Wu of Han, he used the whole country's strength to possess outstanding generals such as Wei Qing Huo Qubing, which were difficult to appear for hundreds of years, but he could not drive all the Huns out of the surrounding Yinshan. The reason was that the Huns learned to use stirrups, and their mobility was greatly improved and it was difficult to completely wipe out."

Zheng Jiadong was silent for a while and replied: "I didn't expect that the small stirrup is so important! No wonder the Central Plains have been disturbed by the Hu people for thousands of years."

The military and political officer smiled mysteriously and said, "The stirrups gave the Hu people an absolute advantage over the Han people. However, the artillery, grenades and muskets of our Jingzhou army gave the Han people an absolute advantage over the Hu people. Did General Zheng hear that the four troops in Lingbei were killed by grenades in just one quarter of an hour?"

The grenade battle of the Wuwei Army once caused a sensation inside and outside the grassland. How could Zheng Jiadong have no idea? Moreover, as an excellent general, Zheng Jiadong often ponders classic battle examples and quickly discovers the fatal weakness of the grenade.

Zheng Jiadong said: "Grenades are certainly powerful tools, but this thing is extremely expensive and the requirements for baggage are ridiculously high. How to apply them on a large scale?"

The military and political officer replied: "Grenades are expensive, but thunderbolts are not expensive? My Jingzhou army still doesn't have the capital to shoot flowering bullets into the Tartar formation. As for transportation, hehe, General Zheng, don't worry..."

The military and political officer deliberately kept it a secret, stopped, and tickled Zheng Jiadong's heart. Zheng Jiadong said, "Brother Qian is not happy, just say something!"

The military and political officer leaned his mouth close to Zheng Jiadong's ear and lowered his voice: "Have General Zheng heard of the rail road from Fangcheng to Ye County? Four heavy horses and pull hundreds of stones of cargo can travel 800 miles a day! From Xi'an to Lucheng, it is about 1,500 miles long. If you build a rail road along the Qin straight road, you can go from Xi'an to Lucheng in two days. What food, grenades, and flowering bullets are still necessary?"

Zheng Jiadong was stunned and asked, "Is Jiangling Hou preparing to repair the rail road along the Qin straight road?"

The military and political officer laughed and said, "It's all rumor, why should General Zheng take it seriously!"

After laughing, the military and political officer squeezed his eyes at Zheng Jiadong again, smiling without saying a word.

Zheng Jiadong suddenly understood the meaning of military officials, and his heart was turbulent and he could not calm down. If there was really such a rail road, what was the difference between Lucheng and Yulin and Suide?

It seems that spring comes and autumn comes, and the winter of nomadic peoples has slowly come. Isn’t it now? This is a great era. If you miss this era, you will be in vain for your life!

Zheng Jiadong was thinking about his own thoughts, suddenly, a loud bang came from ten miles northwest, and then several loud bangs rang out one after another.

The explosion was crisp and sharp, and it was the warning of the cavalry whistle!

"Enemy attack!"

There were waves of roars in Zheng Jiadong's army, and the soldiers quickly moved under the guidance of the officers.

Because the convoy was several miles long, the soldiers and civilians had no time to gather the supplies chariots together, so they had to push the nearby supplies chariots to the periphery, forming three circles around apart, covering the soldiers and civilians in the middle.

The defensive formation had just taken shape, and five or six cavalry rushed to Zheng Jiadong, and reported: "Yijin Holo's tribe, two thousand and five hundred cavalry, came in five divisions and came raiding..."

Two thousand five hundred riders!

Zheng Jiadong took a breath.

Although the two thousand five hundred cavalrymen would not rob the military baggage, if the enemy cavalry kept harassed, transporting the military baggage would almost become an impossible task!

Zheng Jiadong was very worried and immediately sent a messenger to inform Zhang Fengyi of the enemy situation.

Sure enough, as Zheng Jiadong expected, the light cavalry of the Yijin Holo tribe saw that Zheng Jiadong was ready for battle. Most of them were far away and occasionally sent three or four hundred cavalry to rush to the front of the formation, and after randomly fired arrows, they quickly fled far away, which made Zheng Jiadong's tribe very annoyed.

If Zheng Jiadong has no strong support within three days, he will inevitably collapse.

Zheng Jiadong was very grateful, but fortunately, he sent a messenger before the Mongolian light cavalry arrived.

After receiving the order, Zhang Fengyi was shocked and suspicious. She judged that after the Ordos tribes had survived a brief period of chaos, they finally learned from their mistakes and began to take ancient and very effective measures to harass the food road.

In addition to the Ordos tribes, will the Dalat tribes participate in the harassment strategy? What about the Tumote tribes?

If the tribes gathered around Lucheng are united and resolutely carried out harassment strategies, this is really a big problem for the two armies!

With a blazing look in front of him, Zhang Fengyi didn't care about so much and immediately ordered the First Cavalry and Infantry Army to turn around and go south to support Zheng Jiadong.

When the First Cavalry and Infantry Army joined with Zheng Jiadong, they escorted the baggage and continued to travel north. More than 2,000 light cavalrymen of Yijin Holo's army were still unwilling to leave and were far away around the convoy. The First Cavalry and Infantry Army sent troops to expel them, while the Mongolian light cavalry fled in all directions.

The cavalry and infantry soldiers were no match for the Mongols at all. They could only sigh at the horse's butt and could not kill the light cavalry under the horse.

When the cavalry and infantry gave up expulsion, the Mongolian light cavalry was stolen like a slut.

It was like this and it was not until the baggage convoy arrived in Zhang Fengyi's army that the Mongolian light cavalry ran away looking west.

Zhang Fengyi was very worried. Since Zheng Jiadong's troops were harassed, the reserve team escorting the baggage was also harassed.

Sure enough, Zhang Fengyi immediately received a notice that the reserve team of the Wuwei Army was harassed by the Mongolian light cavalry and could not make any progress!

However, unlike Zheng Jiadong's army, the reserve team is closer to Dongsheng City. After asking for help from the Tiger Roar Army stationed in Dongsheng City, Lin Chunyi sent a unit to escort Zhang Fengyi's army.
