From the officials and people of Langmeng County, he learned that Heilongkou was originally a prosperous waterway. When the Fen River was flooding in summer, there were endless wooden queues of cargo ships.

But shortly after Qin defeated Zhao, many terrifying and strange things began to appear at the Black Dragon's mouth. The boatmen who often came and went to and from even merchants and travelers who were rushing along the riverside business roads died strangely, and even mules, horses and livestock would disappear. The herdsmen who grazed nearby and the villagers who chopped wood and collected herbs also disappeared from time to time. The Langmeng County Office and nearby villages and towns also organized soldiers and hunters to investigate, but the truth was never found out.

Later, it was reported that there were black demon dragons in the canyon, devouring past pedestrians, cattle, horses, livestock and even wild animals. Over the past ten years, not only few people dared to walk on the Black Dragon's mouth, but even birds and beasts have disappeared. I heard that they were all swallowed by demon dragons...

In this era, this is a common story.

The people are ignorant and try to pull things to ghosts, gods and monsters when they encounter horror and don’t understand.

But to break this superstitious fear, you need to come up with real evidence.

As a disciple of the immortal family and the left prime minister of the dynasty, Chen Xu had already gained a reputation for every inch of China. He could see the Taiyi Temple with a strong incense everywhere wherever he passed. There were also many people's homes that included the throne of Taiyi Immortal Lord and Qinghe Marquis, and prayed for peace and prosperity in the morning, noon and evening.

Therefore, today Chen Xu went to Heilongkou to check in and used the immortal magic weapon Taiyi Divine Thunder to confirm that the evil dragon was not the demon dragon, but just a group of strange bats that like to eat blood. After the officials and people of Langmeng County became lively and excited.

Based on Chen Xu's understanding and seeing with his own eyes, although it is impossible to calculate how many vampire bats are gathered in the Heilongkou Canyon, the number of black tides that is spreading throughout the canyon is definitely tens of thousands, and to catch all so many bats in one go, you must have sufficient preparation.

After resting for a night, Chen Xu set off to continue to Yanmen Pass the next morning.

Before leaving, he once again reminded officials and merchants and celebrities from Langmeng County who came to see him off.

"This marquis will return from Yanmen for at most two days. You should quickly recruit the people and prepare a large amount of wolf dung pine hair dry diesel wax. It is best to mix some items that can generate poisonous smoke. While the daytime is accumulated at both ends of the Black Dragon's mouth, the more the number, the better. At the same time, the flammable objects on the cliffs on both sides should be cleaned up to avoid the spread of fire and causing fire. The bat usually comes out when the evening is dark. Now that winter is coming, it will not come out to find food easily. It is absolutely safe during the day. After preparation, you don't need to wait for this marquis to return to ignite and smoke it. I hope that when this marquis comes back, you will see the corpse of the bat. This matter is successful. This marquis will report to the First Emperor to ask for me for you. At the same time, this matter will be published in the Daqin Metropolis Daily and spread it to the world, so that the people of the world will know the real cause of Tongwu Hou's death!"

"Thank you, Marquis, I will definitely live up to your expectations. I will definitely kill all these bats within two days!" All the officials and gentry in Langmeng County bowed together to salute.

"It's great, please stay here, I will go~~"

Chen Xu nodded slightly, kicked and whipped, and took Shu Qingrou and a group of guards along the flat cement avenue and headed straight for Yanmen.

"Husband, are there really vampire bats in this world?"

The horses walked with bridles, and the water Qingrou, wearing a hat and covered with a veil, had not yet awakened from the strange situation of the black demon dragon being just a group of bats.

"The world is so big that there are all kinds of strange things. Although bats can fly, they are the most special animal in the world. They are similar to wolf, fox, dog and mouse. They are fertile and breastfeeding, but they have a pair of flesh wings that can fly. They like to live in caves, and they are habitually hiding at night and have ugly appearances, so people don't know much about them. Although bats do not move much in winter, they still need to make regular food in order to ensure that the body's temperature is not frozen to death. These bats have huge fangs and sharp fangs, and have sharp hook claws. In addition, they are huge in number, and attack humans and animals in the face of insufficient food is normal. Vampire bats naturally have various strange stories about vampire bats. There are also many Western countries. Legend has it that there is a vampire bat with an immortal body that can turn into a human form and walk in the darkness. They call it a vampire..."

While rushing to the road, Chen Xu also talked about some messy things about vampire bats to kill time. Ten miles away arrived in an instant. After finding Chen Wu and others who arrived in advance in the service area nearest to Heihu Pass, he transferred to the carriage and continued to go north.

Bats have very ancient legends in the East and the West.

The East uses bats as auspicious objects, which means immortality and fortune. It has been believed to be related to gods and immortals since ancient times. Therefore, bats are common in various ancient jade and bronze sacrificial instruments, while among the people, the images of bats are more common. The images of bats can be seen everywhere on doors and windows, chariots, murals, tiles, bricks and stones. Even the twelve emblems such as the sun, moon, stars, dragons, insects, Yi algae, fire powder, rice, etc., embroidered on the crown garment of the First Emperor, the shape of bats is in the twelve heralds, so in the East, bats are auspicious beasts.

But in the West, bats have always been synonymous with doom, blood and darkness.

The appearance of vampires was based on the fearful and fierce infectious diseases that vampire bats would bring. The earliest vampire image originated from the Black Death that swept across Europe in the Middle Ages.

Every time under dusk, bats are flying all over the dead wasteland.

Crows eat carrion, bats suck blood, these two kinds of animal poop have become ominous things in the eyes of Westerners, and only dark wizards who spread diseases like it.

Although bats are a kind of auspicious beast for the Eastern Qin Dynasty, in Chen Xu's view, the appearance of such a large group of bats in the busy Central Plains is a great threat. Although bats are considered a beneficial beast and can prey on a large number of pests, they also carry a large number of viruses that can cause disease and even be infected, such as rabies, Ebola, and SARS that once swept across China and made Chen Xu remember it deeply. It is normal for such a large group to gather and attack the passing humans, animals and beasts without enough food.

So last night, Chen Xu summoned officials from all over Langmeng County and the rich and gentry Su Lao to discuss the strategy of getting rid of the bats. The final result was to burn smoke with fire.

As these bats entrenched in the mouth of the black dragon were removed, the cause of Wang Ben's death would eventually surface, and the suspicion of the people and the courts of Chen Xu would slowly calm down.

...

Yanmen Pass, as the largest pass in the northern Great Wall, is built between high mountains and ridges. The city wall more than ten feet high is like a gate to separate the former Central Plains from the outside of the Great Wall.

As one of the most famous passes in China, legends about Yanmen Pass are emerging one after another. However, the most famous one is General Li Mu of Zhao State Chen Bing Yanmen Pass, who set out from here several times to defeat the Xiongnu.

"The world is nine barriers, Yanmen is the first, and it is a powerful pass!"

Looking at the towering Yanmen Pass and the undulating geese-shaped city walls on both sides, Chen Xu stopped to observe the horse and couldn't help but be amazed.

The Yanmen Pass is not made of blue bricks and huge stones, but is built with rammed earth and mud. Although it looks a bit dilapidated, the towering city tower and the Great Qin Dragon Flag that flutters in the wind in the cold wind still make Chen Xu feel excited.

It was around the time of Shenshi. The sun sets westward, and the bright light was blocked by the tall city tower. The flags and arrows on the city tower looked like silhouettes, and it was even more majestic and magnificent in loneliness.

"It's indeed a majestic pass, not inferior to the Xianyang City Tower!" Shui Qingrou wore a hat and covered her veil, and stood quietly beside Chen Xu and sighed softly.

"Yes, it can be seen that Zhao State was indeed under great pressure from the Huns at the beginning. If Zhao State had not been fierce enough, I was afraid that the Huns would have been even more plagued by our Central Plains!" Chen Xu nodded, turned around and watched for a while, and gently clamped his horse's belly and said, "Let's go, Jingbian Temple is outside the pass, go to watch and worship General Li Mu. I will rest in Chengguan tonight and return tomorrow morning!"

Now that the Huns have been destroyed, the former border grassland has become the territory of the Dai Kingdom. The Dai Wang Yingkun guarded the northern border, not only brought a large number of Central Plains craftsmen and advanced farming and animal husbandry experience, but also various advanced cultures in the Central Plains. He started a dynasty and established yamen to enfeoff officials, and a large number of disciples of the hundred families who were not good at doing in the Central Plains and ambitious celebrities went to work as officials, opened schools and promoted laws and regulations to educate the Hun tribes, plus the horses of the Huns

Cattle and sheep are extremely complementary to the Central Plains. Fur wool horses have become the largest export commodity of Dai Kingdom, providing Daqin with hundreds of thousands of livestock, millions of furs and wool piled up in mountains every year. In this benign complementary commercial exchanges, not only did Dai Kingdom's development gradually steadily on the right track, but Yanmen Pass, as the Iron Gate Pass that once resisted the Huns, has now become the throat of business and travel exchanges between Liang Kingdom and the Central Plains.

Therefore, although it is almost sunset, the wide open city gates are still full of carriages and horses. The Huns, people from the Central Plains, Hu people in the Western Regions, and even people from the southeast Chu and Yue are all in and out. They are also polite and bow to each other. They are polite and can't see any shadow of being enemies of each other.

"I didn't expect it to be so lively!"

In the midst of the business trips, Chen Xu and his group passed through the city gate. The soldiers guarding the gate kept scrutinizing the crowds with long spears and long swords. They basically ignored the people who looked like Central Plains, and looked at the Hu people and the Huns carefully. If they found people who dodge their eyes, they would immediately stop them and interrogate them carefully.

All the Huns and Hu people seemed to be familiar with this situation. They were not offended and hurriedly lay under the wall for search and interrogation, and even apologized with a smile on their faces.

Seeing Chen Xu, a group of gorgeously dressed and well-motivated people coming out, a hundred generals guarding the gate quickly signaled the soldiers to push the in and out of the crowd and give Chen Xu a smooth road.

After being respected, Chen Xu naturally smiled and nodded to express his gratitude.

As if he was greatly encouraged, the generals couldn't help but hold their fists and salute.

"Hundred generals, do you know this young master?" After Chen Xu and his group came out of seclusion, a soldier asked.

"I don't know you, but you must be a noble man. I'm afraid that the guards will treat you with courtesy when they come!" The hundred generals looked at the backs of a man and a woman surrounded by a group of guards with confusion.

"Don't be too ambitious to destroy one's own might. Guan Shou's identity is probably no one dares to despise him in Xianyang. Who dares to offend the Jiang family now? When he moved down the Marquis of Wucheng, it was a letter from our Mr. Guan Shou. Although this young master is extraordinary, his identity is probably far inferior to our Mr. Guan Shou? Unless he is Marquis of Qinghe..."

There was a silence at the city gate, and then the soldiers who were talking were slapped by hundreds of generals and almost stuck on the wall. "You cowardly, you are so timid. When the Marquis of Qinghe heard that he was still in Liaodong, how could he run outside the pass for no reason? You can take good care of him here, and you will come!"

"Yes, don't worry, we guard the city gate every day, just to be a statue and a decoration. We haven't even encountered a little thief for several months..."

The generals hurried away. Several soldiers at the city gate held Changge and leaned against the city gate, rubbed their hands and feet and chatted and fucked. They would occasionally scold them to maintain order. In the end, they would be over again one day.
Chapter completed!
