Datang: I was tricked by the system

Two hours later.

"Run away, the Tang army has broken through the city!"

"Help, who will save us..."

"..."

With a loud noise, Liaodong City was breached, and Youtang's army rushed into the city like a broken bamboo.

The moment the city was broken, the people in the city shouted in panic.

However, no matter how they struggled and how they fled, there was nowhere to escape.

Gao Yuan led more than [-] soldiers and died in battle outside Liaodong City. At this time, outside Liaodong City, there was a mountain of corpses and a sea of ​​blood, and a strong smell of blood filled the sky above Liaodong City.

Between breathing, it is all blood.

"Anyone who resists will be shot to death." Xue Rengui held up Fang Tian's painted halberd and ordered.

At the same time, several other generals also passed down orders.

Xue Rengui, Shan Xian, Fan Lihua, Cao Xiu and others divided into four groups, and quickly occupied several city gates from four directions: southeast, northwest, respectively.

As for the guards in the city, there are only a few hundred soldiers, how can they fight against Li Yi's hundreds of thousands of troops?It took only a stick of incense to kill him.

All of a sudden, countless signal flares rose in four directions, east, west, north, and bloomed in the sky.

Li Yi rode on the horse and slowly entered the city with the rest of the troops.

After all the soldiers of Youtang entered the city, Li Yi ordered the city gates to be closed, no one could come in and out, and a curfew was imposed.

"Master, mistress, it's been a hard journey, please enter the mansion for a short rest." At this time, the city lord's mansion had already been cleared out by You Tang's soldiers.

Cao Xiu stood outside the city lord's mansion and said respectfully.

"Pass down the order to let the soldiers take turns to rest. After a short rest, we will continue to attack."

Li Yi gave orders to his generals.

Soldiers are very fast.

Taking advantage of the absence of Goguryeo's reinforcements, they took the opportunity to capture a few more cities. At that time, even if the reinforcements arrived, they would be powerless.

"Yes, this subordinate is going to deliver the order." After Li Yi and Lu Ziyu entered the City Lord's Mansion, they went down to convey Li Yi's order.

After rectifying the army and finishing the cleaning work.

Xue Rengui, Fan Lihua, Shan Xian and other generals gathered in the city lord's mansion to discuss the next battle plan with Li Yi.

Attacking Goguryeo this time seems easy, but in fact, it is not so easy to fight, otherwise Li Yi would not have brought so many troops here.

Not to mention that Goguryeo has a large swamp with a thousand miles from north to south and two hundred miles from east to west. This is the first natural line of defense against the attack of the Central Plains.

In addition, Goguryeo relied on the mountainous area, built a 1000-meter-long Great Wall, and arranged heavy-armored troops to defend here.

Without engineering troops, we can only look at the ocean and sigh.

One of the reasons why Emperor Sui Yang was defeated was that he was humiliated by Goguryeo's construction of the capital.

It's just that Li Yi came directly by detour this time.

Besides, after the three conquests of Goguryeo in the Sui Dynasty and the Sui Dynasty, it has strengthened a lot of defense in these years.

Especially last year, Goguryeo built Liaodong, Beisa, Wugu, Gaimu, Xuantu, Buyeo, Domestic, Baiyan, Xincheng and other cities with Liaodong City as the core on the Qianshan Mountains.

In this way, six lines of defense are formed:
The first line of defense: Liaoze, a thousand miles from north to south and two hundred miles from east to west

The second line of defense: Liaoshui
The third line of defense: the Great Wall of Liaodong
The Fourth Line of Defense: Iron Blade Five Cities
The fifth line of defense: the defense in depth composed of old cities such as Buyeo and the country, which is the defense line of Marutu Castle.

The Sixth Line of Defense: The Yalu River Line of Defense

However, these problems were nothing to Li Yi. When he was preparing to attack Goguryeo, he had already prepared all of them.

What's more, with the omnipotent portable space, in front of others, the swamp and Liaoshui may be a huge obstacle, and even need to deploy naval warships, but it is a breeze for Li Yi.

That's why, in just a few days, Li Yi led people to take down Liaodong City, one of the five iron blade cities.

Whether it is the generals of You Tang, or Xue Rengui, they all respect Li Yi like a god, and will not have any doubts about him.

"Your Majesty, where shall we attack next?"

Cao Xiu asked excitedly.

Li Yi glanced at the map, "Since these places are called the Iron Blade Five Cities, I want to see how strong these cities are."

"Xue Rengui."

"Chen is here!"

"I order you to lead one hundred thousand troops to attack Beisha."

"The minister obeys the order!"

"Shan Xian!"

"Chen is here!"

"I order you to lead one hundred thousand troops to attack the black bones."

"..."

Then Li Yi arranged for Fan Lihua to attack Gai Mou.

Cao Xiu and Yan Yunshiba became anxious immediately, "Your Majesty, what about us?"

"The rest is ours!" Cao Xiu pointed to the remaining city: Xuantu.

Li Yi nodded, and continued: "The Tiger and Leopard Cavalry, the Nether Cavalry and the Siege faction and the Yanyun Eighteen Cavalry joined forces to attack Xuantu."

Although there are not many people, but they are all the elite soldiers of You Tang, attacking a city is naturally no problem, besides, you are agile, sneaking into the city quietly, and beheading directly, the effect will be faster.

Next, Li Yi arranged for troops to be stationed in Liaodong City.

……

"Emergency battle report!"

Yuan Gai Suwen was on his way to Liaodong City with more than 20 soldiers, when a spy staggered over on horseback.

"Emergency report from Liaodong City."

Yuan Gai Suwen raised his palm to signal everyone to stop, then frowned and looked at the person who came, "How about the battle report ahead?"

"Report to General, Liaodong City has been captured by the enemy."

At this time, the news that Yuan Gai Suwen killed Rongliu Wang Gao Jianwu's regent had not yet spread, and the soldiers didn't know about it at all, so they still called him the same as before.

Of course, Yuan Gai Su Wen didn't care about this either.

Besides, even if you care about it, this is not the time to care about it.

After hearing what the soldier who delivered the message finished, Yuan Nanchan exclaimed, "What?"

"How could they be so fast?"

In fact, it is no wonder that he was so surprised. In the hearts of the Goguryeo soldiers, they had six lines of defense. No matter how powerful the Youtang soldiers were, they would not have occupied Liaodong City so quickly.

"Is the news true?" Yuan Nanchan asked.

"Reporting to the Major General, the news is absolutely true. This subordinate escaped from Liaodong City." The soldier knelt on the ground and said with a plop.

"Damn it, this king really underestimated that Li Yi." Yuan Gai Suwen cursed, thinking of the humiliation he had suffered, his eyes burst with strong hatred.

"Pass down the order, and the whole army will speed up."

Now that Li Yi had broken through Liaodong City, he would inevitably attack other cities, and he had to stop it.

"Father, my child can't figure out, how did You Tang's army cross the swamp and Liao River?"

Yuan Nanchan was puzzled by this question.

From hearing Li Yi's personal conquest to Li Yi's capture of Liaoshui seemed to happen overnight. He couldn't figure out what happened in the process.

In fact, it wasn't just him who couldn't figure it out, Yuan Gai Suwen was the same.
