Li Shimin pretended to take two breaths, calmed down and said to Li Yuan: "Father, the son-in-law deployed the defense until late at night last night. Suddenly a fresh breeze blew, and I fell asleep. In a dream, I met an old fairy with a white beard and white eyebrows, and the fairy wind looked at me with a smile and said to me: "I am the old man of the Thirty-three Heavenly Doushi Palace. Is there something difficult for me, boy? ’

At that time, Erchen told Lao Jun about the siege of Chang'an by the anti-thief coalition, and Lao Jun smiled and said: "This is a trivial matter, you are my descendant, I should help you resist the enemy, but I can't interfere too deeply in mortal affairs, so I will allow you three chances to ask for help." When the time comes, I will send heavenly soldiers and heavenly generals to help you. ’

After saying that, he drifted away, and Erchen woke up. Li Shimin continued: "After waking up, the son was not sure whether this matter was true, so he did not report to his father in advance and ask his father to forgive him. ”

Li Yuan smiled and patted Li Shimin's shoulder and said, "What is my son's crime, it's too late for me to rejoice." Now that Lao Jun has appeared, the heart of the army will be more stable, and our army will definitely be able to win this battle! After the enemy army is defeated, I will reward you well! After speaking, he glanced at Li Jiancheng very vaguely.

Li Jiancheng was shocked at this glance, for fear that Li Yuan would give up his position as crown prince to Li Shimin. And Li Shimin looked disgusted with gratitude.

The coalition battalion, which was jubilant in the city, was in a hurry and mournful. I didn't know what was going on when I saw a meteor fall from the sky, and then there was an explosion on the left side of the camp, killing all people and animals within a mile radius, leaving a large crater more than six zhang wide. More than 10,000 people were killed and countless were injured. The fire burned for nearly a mile and was devastated. Dou Jiande and others came to investigate in full clothes, and when they saw this human tragedy, countless soldiers fell to the ground and wailed and struggled. But no one came forward to help, and they all ran in panic. Dou Jiande beheaded dozens of soldiers in a row to barely stabilize everyone, and ordered Liu Heimin to investigate carefully but found nothing. Everyone said that this was a natural disaster, all caused by the attack on Tang for no reason, and the troops should be withdrawn immediately, otherwise there will be a catastrophe in the future.

Dou Jiande also ordered his guards to patrol the camp, but anyone who had a gossip to confuse the public was immediately decided. This allowed the coalition forces to settle down.

The next day, Dou Jiande was still rectifying the coalition army, stabilizing the morale of the army, and did not attack Chang'an. And Chang'an City sent hundreds of fast horses to rush to the camp. I didn't see them attacking, and when they reached two hundred paces, they dispersed, running around the camp, shouting as they ran: "Last night it was the King of Qin who cast a spell, and Lao Jun appeared and punished him slightly, so you should retreat as soon as possible, otherwise you will be punished by heaven!" ”

Dou Jiande was so angry that he was smoking, and it took him a night of hard work to stabilize the military heart, which was unstable in these shouts of killing talents. ordered people to hurry up to intercept and kill these bastards, but after shouting, they went back to Chang'an and walked in style. Dou Jiande was helpless, he couldn't attack the city today, so he had to continue to stabilize people's hearts. But people in feudal society are extremely superstitious, and there are always many frightened people of more than 100,000 people. That night, Dou Jiande received a report from his subordinates that many soldiers had escaped from the camp without permission. Dou Jiande was so anxious that he decided that he must attack the city on the third day, and if he delayed any longer, the coalition army would be completely dispersed.

On the morning of the third day, Dou Jiande ordered the soldiers to have a full meal and prepare to attack the city. The first person to climb the city will be rewarded! Only then did the soldiers cheer up. Carrying a ladder and pushing a battering ram, he rushed to Chang'an City with the horn of attack.

Li Shimin also knew that today would be a vicious battle, so he arranged his defense early, and stood at the head of the city wearing the "dragon soul" to command calmly, with his exclusive weapon "breaking the army" inserted by his side, calmly and majestic.

The city is full of eight-bull crossbows that have been improved in literature and art, and literature and art originally thought that there were eight-ox crossbows in the Tang Dynasty, but Li Shimin did not know what the eight-ox crossbow was. I went back and checked the information carefully, only to know that the eight-bull crossbow was a big killing weapon that only appeared in the Song Dynasty. Now the mainstream siege weapon is the trebuchet, and the data record that the trebuchet in the Tang Dynasty was extremely cumbersome, requiring a lot of manpower and a short range, only one hundred and fifty steps, and the heavy trebuchet only had a range of fifty steps.

Without saying a word, he gave Li Shimin the improved design of the eight-bull crossbow. Li Shimin rushed to work overnight, and only then did he build more than 50 eight-ox crossbows that could be made by two people. Twenty were placed in the Mingde Gate, and fifteen were placed in the other two gates. There were quite a few arrows in a hurry, mostly made of ash rods and hardwood, and the sharpening of the end was completed, and there were more than 30,000 arrows. The workshop is still working hard to ensure that there are enough arrows.

When the coalition army was 500 paces away from the city, Li Shimin ordered the Eight Bull crossbow to be fired. With a burst of bows, sixty huge arrows two meters long flew out, knocking down the coalition soldiers like sugar gourds. The soldier who operated the eight-bull crossbow did not look at the battle results, and quickly pulled the bowstring with a winch, loaded three arrows and continued to fire. The shield soldiers of the coalition army could not resist the fire of the crossbow at all, and they barely came to the city at the cost of 2,000 casualties, and the trebuchet and battering ram were all scrapped.

The allied soldiers braved the arrows and set up the ladder to attack upwards. The rolling wood and stones and golden arrows on the city are also thrown down desperately, and Chang'an City is like a man-eating beast, constantly devouring human lives. Literature and Art numbly watched the two sides fight, but there was nothing they could do. He couldn't stop the madness of the ancients, and it also made him more determined to let Li Shimin unify the whole country as soon as possible. Only in this way can this war-torn nation recuperate.

Thinking of this, he didn't care about exposing the secret, put on the Xiaomi No. 1 and picked up the Fang Tian painting halberd and jumped down from the city, rushed through the crowd and went straight to the vanguard general Wang Fubao, his idea was very simple, capture the thief and capture the king first, kill the commanding general, and the coalition army will inevitably be in chaos.

Wang Fubao saw it clearly, the guy who called himself Lu Fengxian actually jumped off the wall more than three zhang high, and was still killing at his side, so frightened that the three souls went out of his body, and hurriedly ordered to besiege and kill Wenyi. Wen Yiran is not afraid of how many swords hit him, just open and close the distance of fifty steps forward with his halberd in a blink of an eye, Wang Fubao can't retreat, and the escapees are killed! He didn't dare to violate this iron law, and as soon as his heart was crossed, he led his guards to kill literature and art. As soon as the two met, Wenyi raised his halberd and split Wang Fubao into two pieces, turned around and walked towards another general.

After fighting for a long time, Wenyi was covered in blood, and there were still a lot of broken organs. Finally, the six generals of the main attack were killed. The enemy army had no leader, and the morale plummeted, and Dou Jiande had no choice but to withdraw his troops and fight again in the afternoon.

When Wenyi returned to the city, he was already exhausted and out of breath, and he had to walk hard. Wen Yi and Wen Er waited at the city gate in the morning. Seeing that the enemy army had retreated, he hurriedly stepped forward to support Wenyi. returned to Li Shimin's big tent, took off his armor and lay on the ground to regain his breath. Li Shimin came to visit, and then went to deploy defenses again.

This kind of attack and defense lasted for half a month, and the coalition army paid 40,000 lives and still did not reach Chang'an City, and more than 30,000 people were wounded. And ** also lost 10,000, and more than 20,000 wounded.

Dou Jiande was very anxious, he couldn't capture Chang'an City for a long time, and the soldiers began to be war-weary, and if they couldn't capture Chang'an City more than half a month earlier, they had to retreat.

Li Shimin's side is not having a good time, there are only less than 90,000 soldiers available in the city, and some families are also starting to move. He has already caught more than a dozen spies who want to contact the enemy army, and if he suffers for a few more days, he believes that there will be more of these people who eat inside and out. Now they can't be cleaned up, some small families will be wiped out when they are wiped out, and those families with five surnames and seven hopes can't be dealt with simply. Their children held many important positions in the Tang Dynasty, forcing them to open a few city gates in a hurry without any problem. And it is not yet time to do it again, and now the people's hearts have become numb, and it is of little use, and it can only be used when the enemy army is on the verge of collapse.

Li Shimin summoned the generals to discuss. Fang Xuanling said: "Your Highness, now that the war is scorching, the deterrent power of our Tiance Mansion is not enough to shock those Xiaoxiao who have ghosts in their hearts, only asking Your Majesty to personally supervise the formation will definitely stabilize the hearts of the people and deter those villains." ”

Li Shimin nodded and said: "Yes, although this king can fight, he is only a prince, and only his father can stabilize the current situation." This king will ask his father for his life. After speaking, he took Fang Xuanling and the eldest grandson Wuji into the palace to face the saint.

Li Yuan is also the emperor who came out of the fight, and after listening to Li Shimin's explanation, he immediately said: "Don't worry, I will pass on the decree tomorrow, and I will drive the expedition in person!" You don't have to worry about those who are restless, I will warn them. I am old, but the knife in my hand is still sharp, I want to see which one I want to try! ”

Li Shimin and the others bowed down and retreated, and as soon as they left the palace, they spread the news that His Majesty was going to put on armor and go into battle. The effect is remarkable, the morale of the soldiers is greatly boosted, and the morale of each is high.

After another ten days, the coalition army couldn't bear it anymore, and Du Fuwei summoned his henchmen to discuss: "Since we joined the coalition army, there are only more than 10,000 brothers left, and if we continue, our soldiers and horses will all be lost here." What can happen even if the Tang Dynasty is destroyed? If you don't have soldiers and horses, don't you let others slaughter them? ”

Fu Gongyi heard Du Fuwei's words and said, "According to the king's wishes, are we going to withdraw the army?" ”

Du Fuwei shook his head and said: "As soon as we withdraw the army, there will be forces to follow suit, and then the coalition forces will disperse, and when the ** recovers, we will be wiped out one by one, and then all forces will not be able to resist the ** attack." As the saying goes: the icing on the cake is not as good as charcoal in the snow. We might as well take this opportunity to invest in Datang, and we can also make a lifetime of wealth. I wonder what the brothers think? ”

Fu Gongyi thought for a while and said: "What the king said is very true, the strength of the Tang Dynasty is unmatched, and the Haojie coalition army will not be able to take advantage of it today, and it will be destroyed by the Tang Dynasty in the future." If you want to be stable, you can only take refuge in Datang, and I agree with this. ”

The rest of the people also agreed, agreeing to lead the people to surrender if they haven't captured Chang'an City in another ten days.

Both sides have entered the most difficult and scorching period. **If you can't hold it, the family will open the door and surrender; If the coalition forces could not hold on, Du Fuwei, Gao Kaidao and other forces surrendered to the Tang Dynasty.
