"Dashuai, the weather in Bingzhou is like this, look at the posture in the sky, it may be snowing in the next few days."

"Oh? It's snowing before November? ”

"Yes, especially in Yanmen, even in August, there has been a time of snowfall."

Han Rong nodded, and did not object, no matter how proud he was, he could tell which was more important than his face and body, and suddenly he felt that he had grasped something important from Gao An's words.

"Hahaha! Snow? That's great! God help me! ”

Han Rong stroked his gray beard and laughed.

Everyone was puzzled and asked Han Rong, Han Rong smiled and didn't answer, but asked Gao Ran if it was expected to snow for a few days, and Gao Ran said that it would definitely snow in three days, so Han Rong let everyone disperse, and went down to ask the soldiers to prepare warm clothes in advance, and did not explain his plan to everyone, and even Gao Ran did not understand what Han Rong was thinking.

What about snow? Even if it snows, the Hun cavalry will reduce the gallop speed, but we are too, both sides have reduced their speed, isn't it still the same in the end?

At noon on the second day, snowflakes fell from the sky, and the snowflakes slowly fell from the sky with her light dancing posture like little elves.

Han Rong looked at the silver wraps all over the ground, and his face was happy.

"Passing on the commander's order! Ordered Gao Lan and Han Fei to lead the army to build the city! Ming Wenchou and Han Meng led their troops to patrol outside, and they must not let the Hun thieves get close and interfere with our army's construction of the city! ”

"No!"

Han Rong's strategy was simple, take advantage of this cold weather to build a city!

Although this kind of earthen city is not strong, it can't withstand the low temperature of Yanmen. As long as you pour water on the earthen city after the city is built, it won't take long for it to freeze solidly, and slashing with ordinary swords can only leave a shallow white mark.

Even if part of the city wall was destroyed by the Hun cavalry, it was not too simple to repair. Just pile up the mound and sprinkle it with water, and another wall is built.

At this point in time, the average temperature in Yanmen today is about 5-10 degrees Celsius. The average daily minimum temperature has dropped to near freezing. In the Han Dynasty more than 2,000 years ago, due to the fact that the greenhouse effect was not as strong as it is now, and it was in a low temperature period, the actual temperature would be several degrees lower than it is today.

"The Chronicles of the Three Kingdoms Emperor Wen" records: In August, the emperor followed the vortex into Huai with a boat master, and was fortunate to Xu from the land. In September, Zhudong patrolled the platform. In winter and October, Xingxing Guangling Ancient City, Linjiang to watch the soldiers, more than 100,000 soldiers, hundreds of miles of banners. [1] It is a cold year, the waterway is icy, and the boat is not allowed to enter the river, but it is returned.

In October of the sixth year of the early Huang Dynasty, even the Huai River froze, and boats could not enter the river. Such a temperature is unimaginable in today's Huai River Basin, so in the north this temperature is definitely enough to build a city by splashing water.

When the ice city was built, Han Rong stood under the city and looked up at the entire ice city. Cast by the faint sunlight through the clouds, this ice city made of sand, stone and water is a mixture of sand and water, exuding a crystalline sheen and sparkling. ————————————————————————————————————————

"Left, King Zuoxian! God, what a miracle! Han! The Han people have the help of the gods! A scout suddenly burst into the makeshift camp of Liu Bao's men, looking panicked.

Liu Bao frowned, he learned Han culture since he was a child, and received the influence of Han culture in the Central Plains, he actually didn't believe in the theory of ghosts and gods at all, for him, ghosts and gods are all false, only the blades in his hands, the soldiers under his command, the cattle and sheep of the tribe and the financial reports are true, and the only use of ghosts and gods for him is to boost morale.

"Panicked, what it looks like! Make it clear! ”

"Han people, Han people built a city overnight!"

"How is that possible?"

"yes, how can it be so fast?"

Liu Bao was not very surprised, the Han people's ability to set up camp and build a city is far from being comparable to their Huns, and it is impossible for them to build a city overnight, but for the Han people, it is just a little difficult.

Liu Bao touched his chin and kicked the sand on the ground.

However, it would be nice to build a castle with sand and a gust of wind blowing through, and it would be impossible to play any defensive role, so this was an opportunity.

"The Han family didn't know that the sand and gravel here were not enough to build the city, thinking that it would be safe and sound, and they must be careless. A few days ago, we were all night raids, but today we gathered all the horses and horses to attack the camp during the day, and they definitely didn't think of it! Defeat these Han family children for me at once."

When Liu Bao led the army to arrive outside the Yuan army's camp, when Liu Bao saw this "earth city" that shimmered with light blue light, he vaguely felt that something was wrong.

"Heaven bless us! Shoot the arrows! ”

(Shengtian is the supreme deity of the Huns)

Although the Huns are cavalry, they have grown up on horseback since childhood, and they are skilled in bows and horses, and a rain of arrows comes in a volley, but to Liu Bao's surprise, after the arrows hit the city wall, there was no effect that he imagined that the arrows were inserted into the city wall, and those arrows all fell to the ground after hitting the city wall, and none of the arrows could be inserted into the city wall.

Liu Bao was dumbfounded, Zhang looked so long that he could almost stuff a melon.

"How is this possible! How can a city made in such a place be so hard! ”

Indeed, the walls of this era were mostly earthen walls, which were far less rigid than those of later generations, and arrows could often be inserted into the walls, which helped the soldiers to climb during sieges and also deterred enemy troops.

Liu Bao did not believe in evil, snatched a spear from his own soldiers, and threw it with all his strength, leaving only a white mark after hitting the city wall, and then it was also bounced away.

This demoralized the Hun soldiers behind him were a little demoralized, and it seemed to them that the Han people had built a city overnight. According to Liu Bao's previous statement, it is impossible for them to build a strong city, and they will collapse themselves. As a result, the city not only did not collapse on its own, but was unusually strong, far stronger than all the walls they had ever seen.

"Has the Holy Heaven abandoned us?"

"The Han people have the blessing of their gods, can we really win against them?"

"yes, will fighting them be punished by their gods?"

Liu Baoke was a first-class mid-stage fierce general, who had hardly encountered an opponent on the grassland, and with his arm strength, a spear could not penetrate the city wall.

"Hahaha! Hun thieves! We have God's blessing, and you and other thieves will not dismount and surrender! ”

In the oblique spur, a group of men and horses galloped over, led by a tiger on the back of a bear's waist, it was the Hebei general Wen Chou, Han Rong had already expected that Liu Bao would take this opportunity to raid, and ordered Wen Chou to ambush outside in advance. ————————————————————————————————————————
