Li Shimin's tactic is to siege but not attack.

Liaodong City is a border town in Goguryeo, a bridgehead-like city. This city is very important. Li Shimin is determined to win it, but conquering it is not the main purpose. Li Shimin hopes to use siege to attract enemy reinforcements, and then annihilate the city and enemy aid in one fell swoop.

To put it bluntly, this is a typical "surrounding the point and attacking the aid" tactic.

This tactic is not a conspiracy, but a dignified and open plot.

My 300,000 army is surrounded by your city. See if you can save it. Liaodong City is a bridgehead for Goguryeo. Its existence is a bit similar to the Xizhou City that Li Su defended back then. It stands firmly like a nail. If Goguryeo wants to stop the Tang army's unstoppable attack, it must not allow Liaodong City to be lost. Once it is lost, the Tang army will occupy Liaodong City and then march straight into it. The rear of Liaodong City is a vast plain area, which makes Goguryeo even more difficult to defend.

Therefore, as Li Shimin expected, the Goryeo reinforcements came indeed, and 100,000 people came, heading straight to Liaodong City with great momentum. The leader was the Nossa Gao Huizhen in the southern part of Goguryeo.

Li Shimin was overjoyed when he heard the news and urgently ordered the drums to gather the generals. Li Ji, Cheng Yaojin, Niu Jinda and other generals all advised him to take the initiative. Li Shimin accepted the advice of the generals and ordered Li Ji to lead 100,000 troops to attack Liaodong City. Niu Jinda led 100,000 troops to detour Liaodong City and attacked Goguryeo reinforcements. Li Shimin led 100,000 himself and lived thirty miles outside Liaodong City to support him.

With the emperor's order, the entire Tang army camp was moved.

The camp was filled with the neighing of war horses, the sound of sharpening swords of soldiers, and the chaotic footsteps of the commander, shouting loudly. After this series of mixed noise, the three armies were ready to go.

Li Su also acted with the camp. The entourages put away the tents and put them on the carriage. Li Su lived a fine life and had more daily necessities. The entourages kept them in an orderly manner and then retreated with Li Shimin's central army.

Riding on the horse, Li Su looked at Li Shimin's carriage marching ahead without saying a word, frowned tightly, not knowing what he was thinking about.

Xue Rengui is now Li Su's personal guard. He quickly adapted to this role, rode his horse calmly behind Li Su's shoulders, and walked forward step by step.

Gao Suhui's foot injury was not healed, and he also divided a horse and followed Li Su's servant. The three of them marched in a triangular pattern, followed by Fang Laowu and Zheng Xiaolou and other troops.

The march was silent for a long time, and Xue Rengui seemed not very comfortable with this uncontrollable silence, so he took the initiative to speak: "Master, do you seem to have something to worry about? Do you attack Liaodong City in a battle..."

Li Su came back to his senses, shook his head and smiled, "No, you're thinking too much, there's no problem with my King's Army taking Liaodong City. This is a sure win. I'm not worried about this."

"But the villain has been frowning when he sees the prince..." Xue Rengui said reluctantly.

Li Su Si asked for a moment and said slowly: "Liaodong Chengke, what I am worried about is the 100,000 reinforcements led by Gao Huizhen..."

Xue Rengui was stunned and said, "Your Majesty ordered General Niu to attack Gao Huizhen's reinforcements. Is it true that General Niu has lost his mistake?"

Li Su suddenly glanced at Gao Suhui on the right, his eyes flashed a little unpredictable, and then slowly said, "Put it in your shoes, if you were Gao Huizhen, what would you choose when you know that the Tang army's 100,000 elite troops were coming towards you? Would you go up to you without hesitation?"

Xue Rengui shook his head: "If a villain is the main general, he will definitely not make such a choice. My kingly army has always galloped around the world and is invincible. It can be said that the world is invincible. The Goryeo Army should know our army's reputation. The commander with a little talent will not choose to fight head-on. One hundred thousand soldiers is not a small number, which determines the fortune of Goguryeo. If a villain is Gao Huizhen, he will definitely choose to attack in a roundabout way, or set up ambush, or use surprise troops to surround the distance, or rely on the advantage of high mountains and ridges to defend, fight step by step, and counterattack at the right time... In short, facing the enemy head-on is the stupidest way."

Li Su sighed and said, "Rengui is worthy of being a general. Yes, I heard that the southern part of Goguryeo, Gao Hui is really a good war commander in that country. He is brave and brave, brave and resourceful. He has been familiar with the military strategy of the Central Plains since he was a child. He is quite familiar with the military use method. He is not comparable to an ordinary stupid commander. Your Majesty sent General Niu to fight head-on, and he is afraid that he has contemptuous thoughts. I am worried that General Niu will suffer a loss..."

While Li Su said, she glanced at Gao Suhui on the side. When she talked about Gao Hui's real name, she found that Gao Suhui was still expressionless and her eyes never had a ripple. Her reaction made Li Su a little disappointed. Her guess, who had originally felt almost inseparable, was shaken at this moment.

Could it be that this woman has nothing to do with Gao Huizhen? So, is it related to the life prolongation of the northern Nusaga?

Xue Rengui, who was standing beside him, was anxious and said, "Mr.'s worries are reasonable. Why don't you hurry up and advise Your Majesty when General Niu has not yet ordered his troops to set off the camp?"

Li Su smiled bitterly: "Do you think Your Majesty can listen to me now?"

Xue Rengui stopped, then sighed and silent with a sad expression.

Li Su rode on the horse, bumping up and down with the rhythm of the horse's step, looking forward with a worried expression.

When utilitarianism defeats reason, there may still be a possibility of success, but the rate of defeat has also increased greatly. Onlookers know that Li Shimin is now dancing on the tip of the knife. No one can tell whether the ending is a victory or a defeat, but because of his stubbornness, the 300,000 Tang troops have fallen into an indescribable crisis.

Li Ji had already ordered his troops to attack Liaodong City.

Since ancient times, sieges have been mostly forcing attacks. In ancient times, cities were surrounded by brick walls into an irregular circle. If you want to attack, the only way is to attack.

Of course, there are also some tricks, such as digging tunnels, recruiting submissions, cheating the city gates, fire attacks, etc. There are many ways, but the success rate is very low. Only by using siege cars and ladders to attack hard can it be the fastest and most effective.

The method Li Ji used was also a strong attack. Before leaving, he issued a military order. Each of the 100,000 soldiers carried a bag of soil. After arriving at the Liaodong city, he chose the east wall as the main attack direction. Using the method of surrounding three gulfs and one, the soldiers threw the soil they carried into the moat ditch in front of the city gate suspension bridge. Each of the 100,000 soldiers had a bag of soil. Soon the moat of Liaodong city was cut off in the waist. After the soil was rammed, the east side of Liaodong city turned into a wide and flat mud land. Finally, Li Ji ordered a cloud ladder to be set up and a stone-throwing cart was set up. First, ten rounds of arrows were thrown into the sky, and then the soldiers carried the cloud ladders, and the claws at the front end of the ladder were deeply pierced into the brick wall. Finally, the soldiers waved their swords and guns to climb the ladders, and fought desperately with the enemy guarding the city.

Since ancient times, the method of siege in cities is generally the same, but nothing surprising. Li Ji rarely takes risks with his troops and is often known for his stability. The same is true for siege in cities. The battle to attack Liaodong City was fought steadily from beginning to end. Every step is reasonable and well-founded. If there were textbooks in the Tang Dynasty, this siege could undoubtedly become a classic case of silently observing old rules in textbooks.

When Li Ji led his army to attack the city, Niu Jinda had ordered 100,000 troops in Li Shimin's central army camp, and was about to leave the camp. He bypassed the war-torn Liaodong City, crossed Niushou Mountain outside Liaodong City, and faced the troops of Gao Huizhen, the troops of Goguryeo reinforcements.

The swords were unsheathed, the war horses were neighing, and the soldiers were wearing swords and stalking out of the camp gate in a majestic manner.

Niu Jinda looked indifferent and cold. He rode on the horse and watched the soldiers step by step by high in fighting spirit, a hint of confusion flashed in his eyes.

From the Battle of Crossing the Liaohe River to the present fight against the reinforcements of Goryeo, the battle to destroy the country was smooth and progressing rapidly, but Niu Jinda felt a little uneasy. He couldn't even explain clearly where this uneasy came from, but he could not convince himself to abandon this inappropriate uneasy.

Half of the soldiers leaving the camp were gone, and the 100,000 troops were not a small number. It would take a lot of time just to watch them walk out of the camp gate. Niu Jinda rode patiently on the horse, looking at the soldiers while thinking about the source of the uneasiness deep in his heart.

A light sound of horse hooves behind him disrupted his thoughts. Niu Jinda turned around, but saw Li Su riding on the horse and looking at him quietly.

Niu Jinda finally showed a smile and waved to him.

"Zi is here to see me off?"

Li Su smiled and said, "Yes, I just came from His Majesty's central army camp. I wish Uncle Niu a victory and a triumphant return."

Niu Jinda laughed: "I have accepted your auspicious words. If you can really return victoriously, I will share the strong wine you have hidden in me, and my love should be a celebration."

Li Su smiled and thought it was, then looked up at the soldiers passing by in front of him. As he looked, Li Su's face couldn't help but become worried.

Niu Jinda lived for most of his life and could observe his expressions. Seeing that Li Su was not right, he couldn't help asking: "Zi Zheng is probably not just here to send me off? I am your winner. I think you are half a father. Just say anything bluntly."

Li Su thought for a while and said, "Boy came here to give Uncle Niu, I have a word I want to remind you..."

Niu Jinda nodded: "I never dare to underestimate your words. Tell me, listen."

Li Su felt warm in her heart. After all, she was her own family. Niu Jinda's attitude was undoubtedly much better than that arrogant emperor.

"Uncle Niu, you are always an expert in marching and fighting. The boy dare not show off his skills. The boy just wants to tell you, don't underestimate Gao Huizhen."

Niu Jinda raised his eyebrows: "How do you say this?"

Li Su pondered for a moment and said, "In the Goguryeo country, there are three people who have real power, besides Quangai Suwen, there are three others. One is Yang Wanchun, who has a self-respecting army in Anshi City, the second is the northern Nossa Gao Yanshou, and the third is the southern Nossa Gao Huizhen that Uncle Niu is about to face. This man is brave and good at fighting, brave and resourceful, and is not a mediocre coach. Uncle Niu must be careful when he goes to fight Gao Huizhen's troops, and he must not be underestimated."

Niu Jinda nodded and said, "I have experienced many battles in my life and have never looked down on any enemy. However, my nephew solemnly reminded me that I will definitely pay more attention to this person. Don't worry, although Gao Huizhen is a famous general in Goryeo, I am not a vegetarian. In this battle, I am 80% sure to wipe out the 100,000 reinforcements from Gao Huizhen's troops."

Li Su smiled bitterly and said, "The boy actually does not agree with Uncle Niu's entire annihilation of Gao Huizhen's troops, because it is not easy to achieve the word "complete annihilation" and often requires a lot of money. Moreover, the boy believes that this time he faces Gao Huizhen, he may not necessarily fight against Uncle Niu's troops head-on, but chooses to launch surprise troops, set up ambush, flooding, fire attack, and even attack camps in the middle of the night. I just hope that Uncle Niu will never fall into his plan. The army must be cautious when advancing and retreating. If you are in danger, don't advance rashly. If you encounter dense forests and burn mountains, in short, don't seek quick success, but only seek stability."

Niu Jinda looked at him deeply: "I discovered that since the Eastern Expedition, you seem to be pessimistic. Why? Do you think the Eastern Expedition will be defeated?"

Li Su lowered his head and said, "You are a veteran who has experienced many battles. In your opinion, can Your Majesty arrange the war properly now?"

A trace of confusion flashed in Niu Jinda's eyes, and then he quickly recovered as usual, and said with a stern face: "No matter what your thoughts are in your mind, remember not to say these words to anyone, otherwise there will be a disaster for death. Do you understand?"

In the end, Niu Jinda was already stern.

Li Su nodded: "I said these words to my heart when Uncle Niu is his relative. I will never say them in front of others. Uncle Niu is not at ease."

Niu Jinda patted his shoulder and said, "The war is imminent. Put away your random thoughts and fight this battle with all your heart. When I return, I will definitely have a good chat with you."

Li Su rode on the horse and bowed slightly: "Boy respectfully sending Uncle Niu, the Tang Dynasty will be victorious!"

Niu Jinda looked at him, smiled slightly, raised his right hand and clenched it into a fist, and waved it hard into the sky: "Tang Dynasty's ten thousand victories!"

After saying goodbye to Niu Jinda, Li Su returned to the Central Military Camp and sat alone in the barracks in a daze.

I want to say a lot to Li Shimin, and even want to rush into Li Shimin's handsome tent, grab his clothes and slap him hard in the face, shouting loudly to wake up, do you know that you have 300,000 lives tied to you, bastard...

But Li Su didn't dare.

He did not have the courage of Wei Zheng, nor was he interested in being a great person like "I recommend Xuanyuan with my blood", greedy for money, fear of death, cowardice, and a little inappropriate sense of justice, which constituted everything in Li Su's personality.

Under the city of Liaodong, Li Ji's siege was not going well. The Liaodong city guardant Zhao Huigong seemed to have the ambition to die with the city. The defenders fought fiercely, and the battles on the top of the city were all exchanging their lives for life. Three days later, the Liaodong city was still in the hands of Goguryeo. Li Ji used all his conventional methods of siege and had not yet captured the city.

Li Ji, who is famous for his steady military use, finally changed his expression after three days of siege and failed.

On the other hand, according to the scout's return, 100,000 soldiers of Niu Jinda's troops had already fought with Gao Huizhen's troops on the plain on the east side of Niu Shou Mountain. The battle between the two sides was tentative and could be said to retreat at a touch. Niu Jinda might have listened to Li Su's advice and took care of Gao Huizhen's troops. He was very cautious in commanding the battle and refused to advance easily. During this period, Gao Huizhen's troops sent light cavalry to provoke and harass the enemy several times. Niu Jinda saw that the other party seemed to be a trick to lure the enemy into the depths, so he ordered to ignore it and let the other party provoke it. He only set up camp at the foot of Niu Shou Mountain, and distributed 40,000 troops to detour on both sides, tentatively attacking and harassing the Goryeo enemy camp.

Both sides went back and forth without using their true power, but the secret intrigues happened in their respective camps every moment.

Time passed quietly by the offense, defense and temptation of both the enemy and us. The last day of the eighteenth year of Zhenguan passed.

On the first day of the 19th year of Zhenguan, Li Shimin sent a messenger to Niu Jinda's army camp, urging Niu Jinda to take the initiative to attack Gao Huizhen, and must wipe out all 100,000 reinforcements from Gao Huizhen's army at Niu Shou Mountain before the Liaodong City was captured.
