Lishi Fortress belongs to Xihe County, tracing its history, today's documents can be traced back to the Warring States Period, which was an important pass for Qin to attack Wei and Zhao, and this time, Ye Zhao wanted to use troops against the state, and Lishi Fortress was naturally the first to bear the brunt.

As an old opponent, although in the past few years, there have not been many direct conflicts between Yuan Shao and Ye Zhao, but since Ye Zhao's soldiers left the customs, Yuan Shao has attached great importance to the Lishi Fortress, not only stationed 6,000 elite soldiers, but also sent a general to guard here.

This general's name is Guo Yuan, if you want to talk about your background, it is not low, Peiguo Guo's family sounds a little strange, but when it comes to his uncle, it is a famous person, that is, Yingchuan Zhong Xuan, at this time, it is important to pay attention to the right family, especially in the scholar class, this is very particular, can marry Zhong Xuan's sister's family, how can it be ordinary?

And Guo Yuan does have some ability, when he learned that Ye Zhao's soldiers and horses in the Hetao entered the state from the clouds, Gao Gan wanted to divide half of Guo Yuan's 6,000 elite soldiers and take them away, Guo Yuan personally found Gao Gan after hearing the news, and analyzed seriously: "Since Ye Zhao is plotting to merge the state, how can he only take one route of soldiers and horses?" And the Hetao is remote, the transportation of grain and grass is unsustainable, it must be a virtual soldier, then Ye Zhao is likely to have secretly sent soldiers and horses, just wait for the general to be pulled by this army of soldiers and horses, and then raid the Lishi Fortress, since then attack and merge the state, if the Lishi Fortress is lost, then Jinyang is in danger! ”

Although Gao Gan felt that the military situation was urgent, he also knew that what Guo Yuan said was good, so he did not move the soldiers and horses of the Lishi Fortress, and led other troops to meet Xu Rong.

And Guo Yuan, after the high-level cadres led the army to leave, they began to set up defenses, around the stone fortress, Minggang and secret posts were laid innumerable, and a lot of traps were dug, no matter how Ye Zhao covered up, once the soldiers and horses in Guanzhong appeared around the Lishi fortress, there was nothing to hide.

"It seems that this Guo Yuan has some ability!" Outside the stone fortress, Ye Zhao couldn't help but smile and said to Xi Zhicai who accompanied the army: "According to the news from the secret agent before, Yuan Shao has deployed 6,000 heavy troops here, and Guo Yuan is so cautious, it seems that there is only one way to attack." ”

Xi Zhicai had seen the terrain of Lishi Fortress during the day, and nodded when he heard this: "Looking at its terrain, this place is indeed easy to defend and difficult to attack, and the terrain is tortuous, and our army's new sky-bombing vehicles, city-breaking crossbows and other heavy siege equipment may be difficult to use." ”

The new siege equipment in Ye Zhao's army is extremely powerful, but the size of these siege weapons is also extremely bulky, like Tianshui and Yixian, the terrain is open, and it is natural and easy to use, but it is difficult to deploy such dangerous passes as Lishi Fortress.

As for luring the enemy out of the city, it is impossible, this Guo Yuan is not an idiot, he has made so many preparations before, obviously he has made up his mind to defend the city, how can he go out of the city to fight at this time?

"And the mountains on both sides are equally dangerous, and our flying boats can't go up." Ye Zhao thought about it, frowned and said, this Lishi Fortress seems to be really difficult to do now, if it is attacked, the loss will be huge, the flying boat cannot accurately choose the foothold now, there will be errors, and it needs to be constantly adjusted, the Lishi Fortress is built between the two mountains, this kind of terrain is exactly where the flying boat cannot reach.

"It's not completely unbreakable!" Xi Zhicai said.

"Oh? What's the trick for Zhicai? Ye Zhao looked at Xi Zhicai and smiled.

"Have you ever noticed the cliffs on both sides of this stone fortress?" Xi Zhicai said with a smile: "You can use a flying boat to send soldiers and horses to the top of the mountain, and from the top of the mountain on both sides, you can not only see the layout of the interior of the Lishi fortress, but also condescendingly release arrows into the fortress." ”

Ye Zhao nodded, when he attacked Luo County in Yizhou, he also used this strategy, and the effect was good, and he nodded at the moment, and now the main force of the flying boat is still parked in the Hetao, and Ye Zhao only followed eight flying boats here, which are used to reconnoiter the enemy situation and can be used as a surprise soldier if necessary, and there is no problem in sending people to the mountain.

There was nothing to say all night, early the next morning, Ye Zhao led the army to the Lishi fortress to prepare to forcibly attack the city, Guo Yuan also ordered troops and horses to meet the battle, the two sides have not yet started the war, the arrows shot from the mountains on both sides fell in the fortress, which did cause a lot of trouble to Guo Yuan, Ye Zhao took the opportunity to wave his troops to attack the city, and Wei Yan overseer army carried the cloud ladder to the city wall to attack.

This ladder is just an ordinary siege ladder, and the ladder to the sky cannot be opened here, and at the same time, a three-stone crossbow swings out in the rear formation and begins to shoot arrows at the city wall.

Guo Yuan ordered people to connect them with shields to block the arrow clusters falling from the sky, and on the other hand, he ordered the archers to counterattack, and the three-stone crossbow could shoot two hundred steps, but in this narrow area, the ultra-long range could not be brought into play, and on the battlefield with limited territory, Yuan Shaojun's archers could also shoot the arrow clusters.

Without the assistance of advanced siege equipment, there are only so many regular siege routines, and the stone fortress is an easy place to defend and difficult to attack, even if Ye Zhao sends vine armor soldiers, they can be pushed down by Guo Yuan's order before attacking the city wall.

After such a strong attack for a day, he failed to break through the Lishi Fortress, Rao is Ye Zhao could only collect his troops, this place was too narrow and not suitable for a large army to fight, and the Lishi Fortress had a sufficient supply of troops, and if he wanted to exhaust the opponent's soldiers and horses, it was not something that could be done for a while.

This kind of meaningless oil war was the last thing Ye Zhao wanted to fight, so he immediately withdrew his troops and did not fight again.

"Lord, at the end of tomorrow, I am willing to lead the vine armor army to rush again!" Wei Yan returned to the handsome tent with a disgraced face and hugged his fist at Ye Zhao.

Before, he fell directly from the city wall, if it weren't for the corpse underneath, even if he didn't die, I'm afraid he would have to cultivate for a long time, he always felt that he was only a little bit close to breaking the city, but just like that, he couldn't get into it after a day, and he was quite unwilling.

Ye Zhao shook his head when he heard this: "That Guo Yuan is deliberately showing weakness to the enemy, trying to lure us to continue the attack, so as to consume the soldiers of our army, my soldiers are much more expensive than Yuan Shao's soldiers, and I can't die in this meaningless battle to add oil." ”

"But this is far from the narrow terrain of the stone fortress, and our army's trebuchets can't be placed here at all!" Wei Yan grabbed his head and said in distress.

"There's always a way." Ye Zhao sat on the rattan chair, looking in the direction of the stone fortress, frowning and muttering about the strategy of breaking the enemy, and releasing arrows from the cliffs on both sides, although it seems to have some effect now, it is not significant, when he withdrew the troops, he had already seen Guo Yuan commanding people to set up a baffle above the city wall, this baffle was pulled up, and it was more difficult to attack it again.

It's a pity that the special operations battalion was sent to Li Ru, otherwise, with the skills of the special operations battalion, it would be possible to take down the Lishi Fortress.

Thinking of this, Ye Zhao seemed to think of something, turned his head and said, "Go and call the people from the Shengong Camp!" ”

"Whoa!"

Soon, the master of the Shengong Battalion who accompanied the army came in and bowed to Ye Zhao.

"How many days will it take me to dig a tunnel here that leads to the inside of the Stone Fortress?" Ye Zhao looked at the master craftsman, and in the Shengong camp, there was a digging army that specialized in digging tunnels.

"Hui Lord, the soil here is dry and hard, and it is not suitable for excavation, and although the city wall of the Lishi Fortress is not high, it should be quite deep into the ground, and it is not suitable for excavation." The master craftsman of the Shengong Battalion bowed down.

"If you can't escape to the ground, then you can only fly!" Ye Zhao suddenly thought that Guo Yuan had erected a baffle on the city wall, and suddenly smiled: "Guo Yuan is cocooning himself this time!" ”

"But the lord has a plan?" Hearing this, Wei Yan looked at Ye Zhaodao.

"Yes, do you remember the parachute used for self-rescue on the flying boat?" Ye Zhao looked at a few people and smiled.

"The lord is wise!" Xi Zhicai's eyes lit up when he heard this, and he nodded and smiled.

"It's just eight flying boats, and the umbrellas they carry are only three hundred." The master craftsman of the Shengong Camp said.

"Then dismantle the two flying boats, do more, and make up five hundred for me!" Ye Zhao looked at the master of the Shengong Camp and said, the material of the parachute is similar to the airbag of the flying boat, similar to the parachute, but it is different, and it is indeed difficult to replace it with other materials in a hurry.

"Whoa!" The general of the Shengong Battalion bowed and said.

"Lord, the last general is going to fight!" Wei Yan was not stupid, and he couldn't help but laugh when he thought of Guo Yuan erecting an artificial roof on the city wall to resist the clusters of arrows from the cliffs on both sides.

"You can skydive?" Ye Zhao looked at Wei Yan in surprise, this parachute jump is not just open in the air, but also to be able to accurately reach the foothold, and this terrain is narrow, but also to ensure that the soldiers will not be entangled with each other.

"The lord should underestimate the last general, and the last general has also been under General Guan for three months." Wei Yan straightened his chest and said proudly.

"Good!" Ye Zhao nodded, and said to Wei Yan: "Give you five hundred vine armor soldiers, three days later, as long as you can help me open the city gate, this battle will be credited with your first merit!" ”

"Don't worry, my lord, if the last general can't break through the city gate, come and see you!" Wei Yan excitedly agreed.

That night, the craftsmen of the Shengong Battalion rushed to make 200 umbrellas overnight, and Wei Yan and the 500 selected rattan armor soldiers were sent to the top of the mountain overnight.

Early the next morning, when Guo Yuan and the soldiers defending the city saw the five hundred rattan armor troops falling from the sky, the whole person was a little confused, even if they shot arrows from above, why did they throw people directly down this time?

After Wei Yan landed, without saying a word, relying on a rattan armor, he slashed the ceiling with a knife, jumped on the city wall, and danced with a single knife in each hand, but seeing the light of the knife, where he passed, there was no general, and the five hundred rattan armor soldiers who followed also joined the battlefield one after another, these rattan armor soldiers were invulnerable, and the reinforcements defending the city were killed and retreated, Wei Yan gathered more than a dozen rattan armor soldiers to kill the city, and wanted to open the city gate.

"Good boy, not a little daring!" Wei Yan narrowly avoided his cheeks, scolded, and turned his head to everyone: "Wait for the city to open, I will kill this thief!" ”

After speaking, he ignored the crowd and took the knife up.

Guo Yuan's martial arts are not weak, at least not under Wei Yan at this time, but Wei Yan is wearing rattan armor at this time, invulnerable, leaving only the face door to be protected by Wei Yan's airtight, the two of them have fought under the city gate for dozens of rounds without winning or losing, but the city gate has been opened, Ye Zhao was overjoyed when he saw this, and waved his troops into the city gate at the moment, Guo Yuan saw this, and could only helplessly lead the army to fight and retreat, but there was no benefit of the city wall, in the face of well-trained and brave soldiers and horses in Guanzhong, the army defending the city was defeated and retreated, and soon became a rout, Guo Yuan knew that it was difficult to fight, had to lead the army to escape from the Lishi Fortress and retreat to Jinyang, preparing to fight Ye Zhao to the death in Jinyang.
