After the roundabout troops arrived, Li Buqi could pretend to be forced. He pretended to hand over the command of the battle to Shi Quanbin easily, and sat on a chair to watch the battle comfortably.

There was more and more wolf smoke behind the Jiaozhi people, and Shen Chenggui also sensed that something was wrong, and the troops he sent out were also beaten back, and reported to him that the Song army coming from the south was by no means a small group of men and horses in the past, but I don't know how many.

This time, Shen Chenggui was furious, and hurriedly ordered the withdrawal of the army. But the striker is playing nervously, how can it be so easy to get out of the fight? As soon as the soldiers heard the order to retreat, they were confused, and those who had no cover turned around and ran. If this is a barbaric fight with Zhancheng and Guangnan Mountain, there is naturally no problem, but exposing his back to the Song army is too slow to die.

When Shi Quanbin saw the wolf smoke, he ordered the troops to attack forward, and as soon as the Jiaozhi people ran, they chased after the Jiaozhi people's butts.

Shen Chenggui wanted to resist the pursuit of the Song army at first, but soon, he was attacked by a Song army behind him. This Song army also attacked with a weapon that could make a loud noise before attacking, which directly destroyed the will to fight of the Jiaozhi soldiers. Shen Chenggui saw that the situation was not good, and hurriedly ordered the whole army to retreat to the camp by the Baiteng River. However, the formation of the Jiaozhi people did not last long, and they were cut off by the Song army and made a mess. At this point, the organized fighting of the Cochins was over.

However, the Cochin people were not good at this kind of tightly organized battle, and they were familiar with escaping in a chaotic situation. In the end, more than 10,000 people commanded by Qi Bin came over, and only captured as many as 12,000 prisoners.

This result is not bad, and it is also acceptable for the "militia" who experienced a big scene for the first time. More than 4,000 corpses were left on the battlefield, plus more than 10,000 prisoners, if you count the scattered Jiaozhi people, the Jiaozhi army commanded by Shen Chenggui is basically finished. Now Li Buqi can rest assured and boldly attack Thang Long Mansion along the Bai Teng River, which is the Hanoi of the later generations.

On the same day, the navy sailed 100 ships specially designed for inland river operations and transportation into the Baiteng River, cut the iron chains on the river, and carried 1,000 marines and some army troops along the river to control the key points. Li Buqi led a large army to march quickly along the south bank of the Baiteng River, leaving only the soldiers and the marines trained by the coastal strongmen to take the prisoners of Jiaozhi to the sea ship and transport them back to Qiongzhou and Lianzhou to serve hard labor.

The discipline of these marines and strongmen was relatively poor, and Li Buqi was afraid that they would stab Lou Zi when they penetrated deep into the enemy's territory, so he gave them a task that was more suitable for them - to go out and plunder the Jiaozhi place.

According to the agreement with Champong, at this time, Champa should have sent troops to attack the south of Jiaozhi, coupled with thousands of Song troops coming out to harass in all directions, which can plunge the entire eastern part of Jiaozhi into chaos, and it is impossible to organize troops to support Thang Long Mansion or cut off the back road of the Song army, Li Bu can safely and boldly attack Thang Long Mansion.

Now that the main force of Jiaozhi was pinned down in the north, the 30,000 men deployed in the east were defeated again, and the people everywhere had no time to recruit, Li Buqi really did not encounter any resistance all the way and arrived at Thang Long City five days later.

For five days, Li Buqi was anxious. It's not that I'm worried that Li Dezheng will run away, but I'm afraid that the Jiaozhi people will empty the Thang Long Mansion. When he arrived at the foot of Thang Long City, Li Buqi took a look at the binoculars and saw that the city gate was closed, and the tall city walls were full of flags, swords and spears, and the defenders were standing full, and he was in a posture of defending the city, and then he breathed a sigh of relief.

Qi Bin, Shi Quanbin and other generals had red eyes--this is the supreme glory of a military general, and the Great Song Dynasty has not had such a grand occasion for decades--they all ran to Li Buqi and asked how to fight. Li Buqi ordered: "The navy patrols along the river, sends a thousand troops to monitor at the south gate of Thang Long City, and the whole army attacks the west gate." ”

Qi Bin asked puzzledly: "The east and north sides of this Thang Long City are bordered by rivers and lakes, and they can be blocked by the water army. However, only 1,000 troops were sent to the south, and if Li Dezheng broke through from the south, he was afraid that he would not be able to stop it. ”

That means that if the King of Cochin runs away, the credit will be discounted. Li Buqi said: "Thang Long Mansion is the capital of Jiaozhi, and there must be gathered Li Dezheng's most confidant generals, as well as high-ranking officials and dignitaries of Jiaozhi. I don't know how many of these people there are, and if they fight to the death, this power should not be underestimated. We have penetrated more than 100 kilometers into enemy territory, and there is no large army behind us to support us, and the number of troops under the city is only just over 10,000 people. In the current situation, it is only a matter of time before Li Dezheng is defeated, and whether he is caught or not is not the key, but the last nail is hammered into Li Dezheng's coffin. Therefore, everything is now the first priority to successfully conquer Thang Long City. When the city is opened, the credit will not be indispensable to you. ”

As soon as he said this, all the generals obeyed the arrangement and prepared to attack the city.

Li Dezheng was also watching the Song army's military momentum from the city tower at this time, and when he saw that the Song army was only preparing in the west of the city, but there was no movement in the south of the city, he guessed that the Song army's strength was insufficient. This added another ten points to his faith.

He had already sent people to recall the army led by his sons in the north, and ordered the officials to lead the people to King Qin, as long as the tall walls of Thang Long City were supported for ten days and half a month, hundreds of thousands of Jiaozhi soldiers could drown this thin Song army.

After this determination, Li Dezheng boosted his morale and went back to the palace with peace of mind. In his mind, if the Song army wants to attack the city, it must first build siege equipment, and it will take at least three or four days before it can start attacking the city, so there is no need to be too nervous.

But as soon as it was dawn the next day, Shen Chenggui, who had fled all the way back from the seaside, reported to Li Dezheng that the Song army seemed to be preparing to attack the city. Li Dezheng hurriedly came to the tower of the west city, only to see that the Song army was already in array in the west of the city, and some siege equipment was sparsely launched in front of the battle.

Li Dezheng looked at it for a while and couldn't help but sneer: "I really hope that the Song people will attack the city immediately, and see how they can capture my Shenglong City like this." Pass the order down, kill a Song man, and reward a piece of cloth! ”

The order was passed down, and there was a thunderous roar of joy on the city walls.

The cheers reached the city, and Li Buqi just waved his hand lightly: "Let's start, blow up the city wall as soon as possible, and we must control the forbidden palace and treasury in the city before it gets dark." ”

The generals agreed in unison, and the commander-in-chief of the siege, Qi Bin, waved the command flag with excitement, and immediately the war drums thundered, and the soldiers pushed the trench carts and ballistae and trebuchets to move forward slowly, and began to shoot the Jiaozhi people who suppressed the city head after the ballistas and trebuchets reached the firing range. The crossbowmen followed behind the trench cart, reached a distance of eighty meters from the city wall, and began to fire arrows, which made it difficult for the people of Jiaozhi below the city tower to look up. Then the wagons were pushed to the edge of the trench, and the planks were lowered and a wooden bridge was built over the trench, from which several small houses with wheels came to the bottom of the city.

The Cochin people hurriedly greeted these small houses with bows, arrows, javelins, stones, and even lighted torches. However, the walls and spires of these small houses were built of rough wood, and the outside was reinforced with raw cowhide, and they were basically immune to these attacks. However, the Jiaozhi people were only curious now, and they were not nervous at all, because they knew that the Song army in these RVs alone would not be able to open the city gate no matter what.

In fact, each of these wooden houses carried a large wooden box full of gunpowder, and now four boxes of more than 500 kilograms of gunpowder have been piled up in the city gate hole. The officer in the last RV left the lead, then lit the incense stick for a long time, and left quickly.

As the caravan hurried across the trench, the crossbowmen turned and retreated. As soon as the crossbowmen retreated to a distance of 100 meters from the trench, they heard the roar of the earth shaking, and Li Buqi could feel the ground trembling under his feet. Looking at the east gate of Thang Long City, the entire tower was shrouded in black smoke.
