Zhao Zhen ordered that Shaanxi's military situation should be reported once a day with an expedited rate of 800 miles, and messengers shuttled back and forth every day, attracting the people's sideways, and the war situation in Shaanxi naturally became the talk of the people after tea and dinner. At this time, there were "well-informed people" who expressed their opinions everywhere, saying that Li Jingluo had predicted that the Xixia people would inevitably come to fight for it as early as when the construction of Yongle City began, and that he had requested that Hedong Road send a group of people to Yulin Mansion, and when the Xixia people came to attack, they would kill from the flank and cooperate with the Song army on Yanyan Road to attack the Western Xia army, but the two ministers and a group of people from the Privy Council deliberately delayed the matter of sending reinforcements to Hedong Road for fear that the three princes would make meritorious contributions to the throne again, and would rather throw away Yongle City than send reinforcements.

The people of the capital are well-informed, and they all know that the four princes are fighting for the throne fiercely, and they firmly believe that there must be a conspiracy in line with the principle of preferring to believe in it rather than believe in it. This time, the reputation of the four princes has become a lot uglier.

The emperor can't care about these now, and after receiving the report that the actual number of the Western Xia army is also more than 150,000, he can no longer help but be ridiculed by the Privy Council, but strictly ordered Hedong Road to send troops to Linfu, but Li Buqi persuaded the emperor to be calm and not impatient, and ordered Hedong Road to slowly march into the army. Zhao Zhen saw that Li Buqi put the overall situation of the country first, and couldn't help but feel a little ashamed of Li Buqi in his heart. However, this is only a matter of thought, for a cowardly emperor, the fear of Neng Chen has been deeply rooted in the bone marrow and is incorrigible.

Li Buqi is really light and light, should eat, should sleep, a pair of strategizing, decisive victory thousands of miles away, Mount Tai collapsed in front of the Confucian general style without changing color, but he added a lot of points to himself among the people. He was really very confident in the defense he had arranged, not to mention anything else, just referring to the city walls designed by mature castles in Europe and post-Renaissance bastions, with thousands of muskets and muskets, as well as trebuchets, it was not something that the Tanguts could easily overcome.

According to the war history written by Zhao Sheng later, when the Western Xia people surrounded the two cities of Yongle and Luowu, they immediately realized that these two cities were different from the Great Song cities they had seen in the past.

Yongle City of the Great Song Dynasty, the outer wall is 5.3 meters high, with more than 30 small horse faces. These horse faces are different from the boxy horse faces on the other city walls of the Great Song Dynasty, they are all polygonal, so as to ensure that the enemy attacking the horse face will be hit by the long-range weapons of the city walls on both sides and have no place to hide. Fifteen meters behind the exterior wall is an interior wall that is wider than the exterior wall. The height of the inner wall reaches 8.9 meters, and you can clearly see the situation outside the city from the city wall, and there are 22 pier-type horse faces up to 11 meters high, which is an unobstructed view of the situation outside the city, and can directly support the battle of the outer wall with strong crossbows and artillery. He also built a war tent with wooden planks and raw cowhide on the outer wall to protect the bows and crossbows of the Tanguts, which was a strong defensive force.

The Tanguts didn't know what was going on at the time, and they hurriedly attacked. As a result, the attacking Tanguts suffered heavy casualties under the three-dimensional blows of muskets, bows and arrows, and guns and crossbows on the outer wall and artillery and crossbows on the inner wall, and they were beaten back without even touching the city wall.

But he did not hesitate at all, and immediately threw tens of thousands of people into a siege on all sides, because this time he drove the tribes of political enemies to send them to death, and there was no problem of distressed casualties at all. After three consecutive days of non-stop offensive and defensive battles, the Western Xia people were killed and wounded, but if it was in the past, the Song army would have been exhausted, but this time the Song army used a lot of gunpowder instead of manpower, and it was still alive and well after three days. However, at this time, he also ordered the Poxi army to build a large trebuchet and a batch of siege equipment. But when Pang Pang was about to rely on a trebuchet to attack Yongle City, the trebuchet of the Song army, which was hidden between the outer and inner walls of Yongle City, suddenly became powerful.

The counterweight trebuchet of Yongle City is used to defend the city rather than siege the city, so there is no need to fire heavy stone projectiles that are enough to cause serious damage to the city wall, only need to throw mud balls and stone balls weighing more than ten kilograms to destroy the wooden siege equipment, and the killing and injuring vital force is good. Because the projectiles thrown are relatively light, although these trebuchets in Yongle City are smaller, the range is not worse than that of the large trebuchets of the Western Xia, and after the use of counterweight, the shooting is accurate, and when several trebuchets and the two 5.5 mm guns on the inner wall are fired together, they can always quickly destroy the Western Xia trebuchet with a large target and requires hundreds of people to operate together. After a burst of fire, several trebuchets built by the Tanguts were all smashed.

After destroying the Western Xia trebuchet, the counterweight trebuchet of Yongle City smashed whatever it saw, and smashed the siege vehicles, ladders and other equipment of the Western Xia people.

The situation was similar on the side of the city, and the Western Xia army that attacked Funing City and Mizhi City also reported that the Song army was well defended and had many weapons, which was difficult to capture. At this time, Wu Zang's hope of achieving a quick victory to help him rebuild his prestige was not realized, and he had to put his hope on encircling the point to send reinforcements. But who is Zhang Kang? It was an old thief who did not fall behind Li Yuanhao, and he and Li Buqi set a strategy early, and after coming out of Yan'an Mansion, they fought steadily all the way, and after advancing to Suizhou City, they did not move, but they sent cavalry to guerrilla trials every day, and there were a series of battles with the Western Xia cavalry. In this kind of battle, the cavalry of the Song army took advantage of it because they were equipped with tiger squat cannons and arquebuses, which could attack and defend. A few days later, the Western Xia cavalry encountered a similar number of Song troops and began to take the initiative to force the battle.

The result was that Pang Pang waited for Zhang Kang to come to the left, and he didn't see the Song army get into his pocket, but what he waited for was the news that the Song army of Linfu crossed the Great Wall with a large number of cavalry and swept away the tribes around Yulin in later generations outside the Great Wall.

But Pang Pang was unmoved, and he was waiting for Zhang Kang's army to die. In order to lure Zhang Kang into taking the bait, he ordered to step up the attack on Yongle City and Luowu City again, anyway, this time he had to be cannon fodder. Under the strict orders of the Yanpang, the Western Xia army frantically flocked to Yongle City and Luowu City like a tide carrying soil bags. In some places under the city, the corpses and earth sacs were piled up to the height of the city walls. So the anxious seed used a big killing weapon, the heaven-shaking thunder specially made by the five hundred ordnance supervisors to defend the city.

These earth-shattering thunderbolts were the size of watermelons at that time, with cast iron as the shell, containing one kilogram of gunpowder, and the sound of the explosion was like a huge thunder, and the killing range reached several meters.

The power of the earth-shattering thunder is very great, but Li Buqi has repeatedly warned the seed and Gao Yongneng not to use it as a last resort. This was due to Li Buqi's distrust of the uniformity of the burning speed of the Shocking Thunder fuse, even though the skilled craftsmen of the Ordnance Supervisor proved to Li Daguan that their skillful skills could make the fuze made of gunpowder burn for almost the same amount of time.

Now that the situation is in crisis, he weighed the pros and cons and decided to use the Heaven-Shaking Thunder. When a wave of earth-shattering thunder was thrown under the city, the space under the city wall was immediately emptied of ten meters, and then the Western Xia people who had just desperately attacked the city all screamed and retreated.

Yan Pang was already red-eyed, he had just received a report that the Song army on Huanqing Road was storming Qinggang Gorge, the Song army on Qinfeng Road was out of Zhenrong Army, and Dong Yu of Qingtang was also watching Lanzhou, he wanted to return to the division as soon as possible to rescue, and there was not much food and grass in the army. If he can't take the city of Oro and Yongle as soon as possible, then this time he will have to return in vain, become a laughing stock, and his attempts to rebuild his prestige will be completely in vain.

However, both the city and the city of Yongle were built by the river, and because of the high water table, it was impossible to dig tunnels. As for the water cut-off, it was cut off a long time ago, but looking at the situation of the Song army in the city, it doesn't look like there is a shortage of water. There are really not many ways that can be used by Yan Pang now, and it is basically left to fill in with human lives. Under the pressure of the situation, he once again strictly ordered the siege of the city, and those who retreated were beheaded.

After another day of meat grinder-like fighting, at night, suddenly a Tangut attacked a huge tent. Although the defenders of the camp stopped the attackers, the attackers succeeded in creating chaos in the camp, and the sleeping soldiers heard someone shouting "Kill the attackers, stay and go home", and saw that the fire in the camp was full of fighting, and some of the tribal troops were the first to leave the camp and retreat to the northwest direction that they thought was safe.

The chaos was not only in the large camps, but almost all of the camps were in the midst of a roar. By the morning, the army under the command of Zang Pang had been scattered, and almost all the troops of the Shenyong Military Division and the Xiangyou Military Division of the Left Wing had fled, and most of the small grain and grass had been destroyed. Now like this, even if he wants to continue the siege, it is impossible. Seeing that the situation was not good, Pang Pang hurriedly led his troops to flash. However, the army of more than 100,000 people suddenly changed, and it was impossible to completely cover it up, and two days later, Zhang Kang, who had received the report, led the army to cover up and chase Yinzhou, beheading nearly 10,000 people.

This time, more than 30,000 corpses of the Tangut people were cleaned up under the city of Luowu and Yongle alone, and it is estimated that the loss of the Tangut personnel exceeded 70,000, which was a major defeat that had never been seen since Li Yuanhao.

The good news came to Tokyo, and Zhao Zhen had a grinning mouth left on his whole face for a few days. Li Buqi told him that the Song army could not deal with the wheel war, and the prestige had been lost, and the Tangut people would be completely disappointed in it before they would rebel in front of the battle, and at present, there was no figure in the Western Xia who was enough to suppress the existence of the Pang, and the civil strife in the Xixia would inevitably intensify in the next step, as long as the continuous high pressure on the Tangut was maintained and the Tangut people were not allowed to slow down, the victory in the Battle of Mizhi was the beginning of the collapse of the Tangut.

Then, Li Buqi wrote a chapter, which shocked the emperor and his ministers to the ground - Li Buqi proposed that he had worked hard to plan the strategy of Shaanxi in the past few years, and he was exhausted, so he begged for a bone.
