However, Feng Deyi is the most likely to see the wind and rudder and curry favor with those in power; He offered secret advice to Tang Gaozu, so that Gaozu Dayue was appointed as the Inner Shi Sheren, and soon he was promoted to the Inner Shi Shilang; Let him and Yu Wenshi assist his son Li Shimin together. However, Feng Deli secretly defended the crown prince Li Jiancheng, vacillating between the prince and the king of Qin.

This matter has always been unaware of Li Shimin; Until after the death of Feng Deli; Tang Taizong learned of his affairs at both ends, and Li Shimin was furious and chased after his gift and changed his name to Miao.

Li Shimin knew that Feng Deli was more tactful, and he also had deep trust from his father; arranged for him to go back to Chang'an to report to Li Yuan.

Emperor Li Yuan, who was far away in Chang'an, heard that the siege of the city at the front line had been frustrated, and that the army had no fighting spirit, and hundreds of people fled every day. Some people suggested that this attack on Luoyang had already occupied a large area of land, and that it should rest and recuperate, and wait for the recovery before sending troops.

Li Yuan thought that it was reasonable to secretly issue an edict and order Li Shimin to lead the army back. Staff officer Feng Deyi was appointed by Li Shimin to take a post station and quickly enter the court, and relayed his analysis of the battlefield situation to the emperor in person.

On the Taiji Palace, Feng Deyi analyzed Emperor Li Yuan: "Although Wang Shichong has many places to Li Mi, most of them are superficial relationships. The only one who really listened to his orders was Luoyang City. He has tried his best to exhaust his wisdom, and Luoyang City is about to be conquered.

If you are a class now, the enemy's power will be restored, and if you connect with each other from now on, and get the granaries of Luokou and Huiluo, it will be difficult to deal with in the future! ”

After hearing this, Li Yuan felt reasonable, so he accepted Li Shimin's opinion. Let him lead his troops to continue the attack on Luoyang.

As soon as Feng Deli left the palace, he was stopped by Li Jiancheng's guards, and then he was invited to the palace. After a long night of talking, the second person, Li Jiancheng, went to the Golden Palace, and besieged Luoyang with Li Shimin for half a year, and he was tired of hard work; Request that the third brother Li Yuanji continue to besiege Luoyang instead of Li Shimin, and let Li Shimin come back to rest.

Although Li Yuan did not directly agree, he also agreed to consider it. Li Jiancheng excitedly went down to the temple and went home.

The eldest grandson Wuji got the news and hurried to see his sister eldest grandson Wuji, and the brother and sister had finished their discussion; The eldest grandson went to the palace to ask to see Li Yuan.

Li Yuan is very satisfied with his daughter-in-law, the eldest grandson Wujian is in charge of the size of the Li family's backyard, and everything is arranged in an orderly manner; Li Yuan trusted deeply, and the ministers also disagreed.

The eldest grandson Wujian is very filial to Li Yuan, no matter how busy things are, he never lacks a greeting every morning and evening; Even if he was seriously ill and couldn't get out of bed, he also arranged for his personal subordinates to come to condole.

Hearing that the eldest grandson Wujian was here, Li Yuan was in a better mood and asked people to invite her in. The eldest grandson Wujian came in to kneel down to Li Yuan and ask for peace, and Li Yuan hurriedly asked someone to help her up.

After the eldest grandson Wujian greeted Li Yuan, he frowned and asked, "Why is my father worried, but what has happened unpleasantly recently?" You have the hope of the world, and you need to take care of your health. ”

Li Yuan laughed and said: "It's still a virtuous daughter-in-law who is filial, don't worry, I'm just to send someone to lead the troops to attack Luoyang, and it's difficult to choose for a while; Do you have any opinions? ”

The eldest grandson Wujian hurriedly said: "Father, this is a major event in the imperial court, where do I dare to put a beak in a female stream, I dare not say." ”

"This is the family, not the court, but you say it's okay."

The eldest grandson Wujian said: "My father and eldest brother are both benevolent and virtuous lords, and they can set an example for all generations; to educate the world; But the sword soldier is a matter of killing, and there is a dry heaven and peace; The saints do not want to see it. And King Qin is a subordinate, and he is the son of his father, so he should naturally share his father's worries.

Since you don't want to do this, why don't you leave it to King Qin to do? Moreover, the crown prince and the king of Qin are separated from each other, so there are fewer contradictions; can bless the father's foundation for thousands of generations, and the blessing will last. ”

Li Yuan nodded secretly when he heard this; The eldest grandson Wujian got up again and said goodbye to Li Yuan and returned to the Qin Palace.

The next day, Li Yuan decided to keep Li Shimin as the head of the march and continue to lead the army to besiege Luoyang.

Li Jiancheng was dumbfounded when he heard this, but the holy decree did not change at once; He could only complain in his heart. Li Yuanji, who was in Tongguan, was furious and thundered, smashing the cups and plates in the mansion to the ground.

Xu Shiji secretly contacted Wang Shichong's old Wagang generals, and these people saw that Wang Shichong was in a good position and agreed to surrender to the Tang Dynasty.

On 30 February, Shen Yue, Wang Shichong's Zhengzhou soldier, secretly sent an envoy to Li Shimin to ask for surrender. Li Shimin ordered Wang Junkuo to take advantage of the dark night to lead troops to attack the tiger prison, and Shen Yue acted as an internal response, secretly opened the city gate, and introduced the Tang army. The Tang army then captured the Tiger Prison and captured alive the Great Zheng Jing King Wang Xingben and the Changshi Dai Guan.

Wang Shichong's Wuzuo Guancheng outside Luoyang was all lost within one day, and the barrier in the east of Luoyang was flattened; Luoyang has truly become an isolated city.

Li Shimin commanded the Tang army to dig a deep trench outside the eastern capital, and after the trench, a long wall was built, completely cutting off the eastern capital from the outside world.

Emperor Dazheng Wang Shichong did not go to the court for many days, stayed in the harem, and was stunned with a military book in front of him. Occasionally cheered up, spread out the plan, turtle piece, and repeatedly calculated when Dou Jiande's reinforcements would come and what the chances of victory were. Fiddling around, he fell into a state of dementia again.

Dou Jiande didn't expect that Luoyang would perish so soon, and now Wang Shichong's envoy, the eldest grandson An Shi, went to the palace every day to beg for it. He also knew he couldn't wait any longer; So he personally led an army of 100,000, known as 300,000, and set off from Huazhou to aid Wang Shichong.

They attacked everything along the way, were invincible, and successively broke through Yuanzhou, Liangzhou, and Guanzhou, and came to the Tiger Prison Pass; was stopped by Xu Shiji and Wang Junke, who were stationed here, and they could be regarded as stopping.

The news that Dou Jiande came with 300,000 troops made Luoyang boil. On the contrary, there was a panic in the Tang army. Including Xiao Yu, Qu Tutong, Feng Deli and other important ministers and generals have asked Li Shimin to temporarily avoid the edge, Li Shimin believes that the Tiger Prison Pass is easy to defend and difficult to attack, and it is impossible for the Xia army to converge with the Wang army in the city in the short term.

In the face of everyone's doubts, Li Shimin was still not in a hurry; His voice was not high-pitched, it was still so soft and steady.

"Dou Jiande broke Xu Yuanlang, the soldiers were very arrogant, and our army occupied the tiger prison and choked him. If he ventures to fight me, it will be easy for me to destroy him.

If he is suspicious and does not dare to attack me, then, within twenty or thirty days, Wang Shichong will run out of food and will collapse on his own. The forces of our army under the eastern capital can be transferred to the eastern front, and they will completely overwhelm Dou Jiande in terms of strength and momentum. Therefore, it is very certain that our army will annihilate the two heroes in one fell swoop, it depends on how we act! ”

Li Shimin turned his gaze to Feng Deyi and the others and continued: "If our army does not rush over in time and let the enemy capture the tiger prison, all the prefectures and counties in the Hanoi area have just been annexed, and the people's hearts are not stable, and they will definitely not be able to hold it; When the two great enemies meet successfully, their strength will be greatly increased, and then we will be defeated by the enemy! ”

Qu Tutong always felt a little uneasy, the hundreds of thousands of troops against the king on both sides, in the past, they could fight against the Tang Dynasty if they took out any one of them, and now they are dealing with them together; Let him feel fear inexplicably.

Under the influence of this inexplicable fear, he once again asked to take the initiative to relieve the siege of the Eastern Capital, so that the Tang army could retreat to the dangerous area and respond according to the development of the situation. Li Shimin shook his head in denial.

Li Shimin remembered Cheng Zhijie's words, gritted his teeth and said, "I have already made up my mind!" And so it was decided! Let's talk about how to deal with these two armies! ”

Everyone was stunned, but seeing the firmness in King Qin's eyes, they felt that the current boss had the majesty to look down on the common people. Now that the boss has made the final decision, the generals have expressed their obedience. Then everyone began to discuss some of the specifics of the simultaneous two-front operation.

At this time, someone reported that Xu Shiji, who was in the tiger prison, had a letter delivered. When Li Shimin heard this, he hurriedly asked the messenger to come up.

After the messenger greeted the king of Qin and the people, he presented a thick letter. Li Shimin took it in his hand and watched silently. As his fingers flipped over, the smile on Li Shimin's face grew thicker and thicker.

After reading the letter, he laughed and said: "Xu Shiji, who knows me, is also!" Today, he offered the strategy of capturing Dou Jiande and Wang Shichong, his vision is very unique, and the strategy he planned is simple and feasible, which is really a miracle in the world.

I had a vague idea of this, but when he added and explained it, it was like a young seedling being moistened by the sun and rain and growing golden ears of wheat. If I annihilate the two heroes in one fell swoop, I should take the first credit for him! ”

Saying that, Li Shimin passed the letter to Cheng Zhijie, and Cheng Zhijie read it at a glance and ten lines, and then passed it to Qu Tutong and others.

After reading it, everyone was amazed, and then ran to the front of the map, and discussed and supplemented the map one by one according to Xu Shiji's strategy.

The big plan has been decided, and the details have been completed. Li Shimin pondered for a moment again. In the silence, his demeanor was solemn and serene, full of indescribable majesty. The audience was silent, and even a grain of rice could be heard.

Li Shimin then issued a military order softly: the Tang army was divided into two parts, and one part was dominated by Qu Tutong to continue to besiege the eastern capital. The other part was led by Li Shimin to the Eastern Front.

As soon as they decided that there was a big chaos outside, someone came in to report that Li Yuanji, the king of Qi, had arrived. As soon as Cheng Zhijie and the others heard that Li Yuanji was coming, a fierce light appeared in their eyes.

Li Shimin sighed and said, "I decided to lead Li Yuanba's three thousand ironclad army and the army of the Great Demon Kingdom to the Tiger Prison together. The military situation is urgent, please go and prepare first, let's set off today. ”

Cheng Zhijie agreed, and led his generals to turn around and leave the big tent. Only then did Li Shimin invite his younger brother Li Yuanji in. Li Yuanji's face was gloomy, and after entering the big tent, he said: "I don't want to press grain and transport grass in the back, I want to go to the front to fight and make meritorious contributions." ”
