Huayin, Tongguan.
The majestic Guancheng is full of the sounds of military orders and drums, as well as the dense sound of bowstrings.
"Bang!"
Suddenly, a heavy sound came from the city wall.
A huge stone hit the city wall, knocking down pieces of rammed earth, causing many nearby Hun soldiers to scatter to both sides.
Hu Yanyan, the Han cavalry general of the Xiongnu, had his face covered with loess and dust. Three consecutive days of fierce fighting had exhausted the Xiongnu soldiers in Tongguan.
"General Huyan, no, if you continue like this, I'm afraid the thieves will break the morale of the army!"
A general complained to Hu Yanyan with a frown on his face.
"Then what can we do? If we go out of the city to destroy the thieves' stone cannons, should I send you there or let me go?" Hu Yanyan said angrily.
Since more than ten days ago, the Huns soldiers led by Hu Yanyan appeared first behind Tongguan.
After tens of thousands of Tongguan defenders saw Hu Yanyan's flag, they rioted again, scaring away the younger brother sent by Jin Zhun.
Then these Xiongnu soldiers opened the city and surrendered to Huyanyan.
Two days later, Liu Yan, the governor of Hansi Prefecture, led an army of 30,000 people and appeared outside Tongguan City.
Regarding Liu Yan, his defeated general, Hu Yanyan didn't pay attention to him at all at first.
However, as the two sides gradually started fighting, the Han army soldiers under Liu Yan caused Hu Yanyan to suffer a lot.
These Han army soldiers were so courageous and powerful that they almost deployed the stone cannons for the siege under the noses of the Tongguan defenders.
The huge projectiles thrown by the stone cannons broke open small holes in the solid Tongguan city wall.
Naturally, Hu Yanyan couldn't sit still and sent out two sneak attacks with the intention of destroying the Han army's siege equipment.
But they all suffered serious losses, so that now they can only watch the Han army playing with the siege equipment to wear down the city wall.
"General, if you can't attack by force, why not outwit it!" said the general.
"How to outwit?" Hu Yanyan asked.
"General, there are mountain roads to the south of Tongguan that can lead to the backs of those thieves. Why not send a lot of elite troops to cooperate with the garrison of Guancheng inside and outside to defeat these enemies in one fell swoop?"
"Mountain road? I think there has been no traffic there for several years. It is already overgrown with weeds and trees. How can you identify the road?"
Hu Yanyan had more soldiers and horses than the Han army outside the city, but they were all used to riding and shooting or charging to destroy the formation. However, their ability to defend the city was not as good as that of the Han army outside the city to attack the city.
"General, don't worry. I have traveled in Huayin before and I know the mountain roads very well. Even if the road is blocked by weeds, I can pass through it with just a little identification!"
Hu Yanyan had heard about these rugged mountain roads.
However, those mountain roads are difficult for the army to pass. Otherwise, once intercepted by the enemy, they will be completely unable to launch a counterattack and will only become the enemy's prey.
"Are you sure about this?" Hu Yanyan asked again.
Nowadays, the situation in Tongguan is too passive. Watching the Han army attack the city wall like this, it will be a matter of time before the city is broken.
The Xiongnu Emperor Liu Yao had just surrounded Chang'an, and the outcome between him and Jin Zhun had not yet been decided.
If anything goes wrong at Tongguan, Liu Yao may be defeated.
"General, don't worry, we are 100% sure of the outcome!" the general said.
"Okay! How many troops do you need?"
"Five thousand is enough!"
"Okay, then I will give you five thousand soldiers and horses!" Hu Yanyan immediately agreed happily.
Almost all of these five thousand soldiers and horses were Xiongnu who slaughtered everyone, which was the foundation of the Xiongnu and Han Dynasty.
Now that everything is in the hands of this general, it shows that Hu Yanyan is so pessimistic about the situation in Tongguan that he resorts to such a risky strategy.
Looking at the general's leaving figure, Hu Yanyan withdrew his gaze again and looked in the direction of Chang'an.
"Alas, Guanzhong has become a dilapidated white land now. Even if Jin Zhun is destroyed, he still won't have the strength to resist these Qingzhou thieves!"
Unlike Hu Yanyan, the Hun cavalry general who gradually fell into pessimism at Tongguan Pass, Liu Yan, the governor of Sizhou and the general of Zhenxi in the Han Dynasty, is in a very good mood now.
"Hahaha, blast me! Bang hard!"
Liu Yan smiled while stroking his beard, urging the catapults to continue throwing stone bombs at the city wall.
"good!"
After more than a dozen artillery carts were thrown, only one shot hit the Tongguan city wall, but it still made Liu Yan, the governor of Sizhou, very happy.
"General, there are not many projectiles needed for the stone cannon!" A general in charge of the siege equipment came up and said.
"It's only been used for a few days, why is there not much left?"
Liu Yan was very excited when he heard this. Ever since he received the emperor's promise of reward, Sizhou Governor Liu Yan had been trying to attack Tongguan head-on.
Because he knew that there was not much time left for him, and the emperor was planning to launch a surprise attack on Guanzhong by water. If this surprise attack succeeded, the first victory in regaining Guanzhong in the future would not be his.
"General, it's not easy to move this kind of material. We need to use local materials. These stone cannons are used too fast, and we can't keep up with the speed of making stone bombs." The general said.
"Then quickly come up with a solution! I'll give you the power to do it cheaply, and you can gather manpower and material resources within a radius of twenty miles!"
As Liu Yan spoke, he turned to look at the Tongguan City Wall not far away.
"The thief who hates the family and the country is right behind the city. If I can't conquer the city first, I, Liu Yan, will be delusional!"
The general knew that Liu Yan's close relatives had died at the hands of the Huns, so he naturally hoped to kill the enemy with his own hands.
"Don't worry, general, I will do my best to get it done!"
After that, the man hurriedly went to prepare.
Liu Yan, the governor of Sizhou, looked at the Tongguan city wall again and found that several walls on it were slightly damaged.
