Since then, the military generals of the Northwest Forbidden Army have been lying in front of the sand table almost every day when they have nothing to do, pondering by themselves, and sometimes a group of people also express their opinions and argue so red-faced that Zhang Qi can't cry or laugh. Zhang Kai also likes it, and from time to time he also conducts research and ideas in front of the sand table, looking for more offensive ideas and strategies.

With the help of the military sand table, Zhang Ji became more flexible in formulating a plan for retreating from the enemy, and more firmly implemented the strategy put forward by Wu Zhi, intensified the attack and harassment of the party army besieging Pingxia City, and thoroughly implemented Wu Zhi's policy of "the enemy advances and I retreat, the enemy is stationed in and disturbs me, the enemy is tired and I fight, and the enemy retreats and I pursue", so that the Empress Dowager Xiaoliang and Li Qianshun had to divide a large number of troops to deal with the Song Dynasty coalition army's return reinforcement and harassment, and the siege force was obviously much weaker, which greatly reduced the pressure on Guo Cheng's defenders to defend the city. At the same time, Zhang Ji was also in accordance with Wu Zhi's idea of "daring to surprise troops", began to transfer troops to punish generals, preparing to send several cavalry armies to break into the territory of Western Xia, gather troops to annihilate the enemy troops in Tiandu Mountain and Yanzi Mountain, Wu Zhi participated in the formulation and improvement of the offensive strategy.

The Jingyuan Road Army was divided into two routes, the left route army was led by Wang En, the deputy governor of Jingyuan, who guarded Longgan, and the Deshun army was the main force, and the deputy generals Wu Zhi and Liu Zhongwu, Wu Zhi led the Red Guard Battalion as the advance battalion to go first, and went north through Anguo Town, Liupan Mountain, Huaiyuan Village, and Ning'an Village, and Liu Zhongwu led 5,000 Zhenrong cavalry to follow, and Wang En sat in the middle army; The right route army was led by Zhong Fu as the commander, Miao Lu and Yang Weizhong as the deputy generals, led the cavalry of the 3,000 Zhenrong Army, passed through Pengcheng Town, Ping'an Village, and Jing'an Village to the north, bypassed Pingxia City, and went straight to Yanzi Mountain in Xixia.

The three armies of Xihe Road, Yanyan Road, and Huanqing Road along the Hengshan border assisted from the side: the general Chong Pu and the deputy general Wang Sunchen led the order of the commander Wang Wenyu to lead 3,000 cavalry on the Xihe Road to Tiandu Mountain to cooperate with Wang En's left route army to fight; The general Wang Shu and the deputy general You Shixiong led the commander Lu Huiqing to lead 3,000 cavalry on Yanyan Road to Yanzi Mountain; General Wang Zhen and deputy general Wei Zhao led the commander Sun Lu to lead 3,000 cavalry from Huanqing Road to assemble at Yanzi Mountain, and the two armies of Yanyan Road and Huanqing Road cooperated with Zhong Fu's right route army; At the same time, the general Li Zhongjie also organized a thousand cavalry to infiltrate the mountain and wait for an opportunity to attack the enemy camp in the mountain.

The soldiers were fast, Wu Zhi led the Red Guard Battalion and a hundred baggage troops, collectively changed into the clothes of the captured party members, got into a carriage, and marched flexibly, Weizhou to Tiandu Mountain is more than 400 miles away, everyone traveled day and night, and it only took a day and a half to arrive near Tiandu Mountain.

Wu Zhi took advantage of the nightfall to set up camp at the southern foot of Tiandu Mountain, repaired on the spot, and sent scouts to disguise themselves as Xixia people to the north to quietly investigate the news.

Early the next morning, the scouts returned with the information they had discovered. Eight miles away from the detour, in the Tiandu village at the northwest foot of Tiandu Mountain, inside and out, densely packed with the military camps of the party people, it is estimated that there are 70,000 or 80,000 people, but the guards are lax, and the party people are stationed in their own country, and it is estimated that they never dreamed that there would be a Song Dynasty army commander driving straight into the tiger's den. Wu Zhi looked at the information in his hand, and smiled a little dumbly, it was a good opportunity for him to be paralyzed and careless!

Wu Zhi took Lin Chong, Wang Jin, Sun Qi, Li Tingliang, Suo Chao, Li Zhenguo, Si Fangguo and others to quietly climb Tiandu Mountain, climb over the mountain beam, and touch the halfway up the northwest foot of Tiandu Mountain, and approached to observe the enemy camp and the surrounding terrain. Tiandu Mountain is not very high, and the people of Wuzhi easily crossed the mountain beam to reach the northwest foothills.

The big camp of the party people is built at the foot of the northwest foot of Tiandu Mountain, backed by Tiandu Mountain, the military flags are dense, the camp tents are continuous, and there are incomparably chaotic, there are only two roads out of the camp, one is the north road, and the other is the southwest road leading to the border. Wu Zhi's current position is just condescending, overlooking the entire camp, more than two hundred meters away, if it weren't for the fear of being discovered by the party members, Wu Zhi and they could actually get closer. The forest on the mountain is tall and dense, and if you don't pay attention to it from the bottom up, it is actually difficult to find Wu Zhi and his party.

Wu Zhi pondered while observing, and gradually had a spectrum in his heart and set a plan of action. So, Wu Zhi quietly returned to the Red Guard camp with everyone.

Back in the camp, Wu Zhi immediately convened all the leaders above the captain level, held a mobilization meeting, and set a plan of action. After Liu Zhongwu's 5,000 cavalry and Chong Pu and Wang Sunchen's 3,000 cavalry arrived, they launched an attack.

In the summer, the cavalry led by Liu Zhongwu, Chong Pu and Wang Sunchen finally arrived at the southern foot of Tiandu Mountain, and settled in the camp opened by the Red Guard Battalion and repaired on the spot.

After Liu Zhongwu, Chong Pu, Wang Sunchen and the cavalry had dinner, Wu Zhi convened a meeting of the generals above the battalion level to explain his action strategy to Liu Zhongwu and the cavalry generals such as Chong Pu and Wang Sunchen, that is, he would take the party members by surprise and catch the party members off guard. It is stipulated that tomorrow morning the fourth watch cooks, the fifth watch gets up, and the sixth watch sets off, wraps the horse's hooves and moves forward silently, and quickly approaches the enemy camp before the enemy army wakes up, and has 8,000 cavalry surround the southwest and north gates of the enemy camp respectively, waiting for an opportunity to move; The Red Guard Battalion lurked to the northwest foot of Tiandu Mountain, close to the enemy camp, and after the Red Guard Battalion launched an attack, when the enemy army fled from the camp in a hurry, the 8,000 cavalry launched another attack to pursue the enemy army, in order to annihilate the enemy as much as possible.

Liu Zhongwu and Chong Pu, Wang Sunchen and other cavalry generals were a little puzzled when they heard this, and looked at each other.

"Isn't it too hasty to attack tomorrow? And Lord Wu decided to attack the Red Guard Battalion first? Chong Pu couldn't help it anymore and asked questioningly. In addition to Lin Chong, Wang Jin and the other four members of the Red Guard Battalion, the others also looked at Wu Zhi, waiting for him to explain.

"Yes, the soldiers are fast, and they will attack tomorrow! And rest assured! The Red Guard Battalion can complete the early attack mission! Wu Zhi said with a smile, and he didn't explain either.

Liu Zhongwu, Chong Pu, Wang Sunchen, and other cavalry generals were suspicious, and when they saw that the Red Guard Battalion had no cavalry, they could not think of how the Red Guard Battalion would launch an attack at that time.

But the military order is like a mountain, and they don't dare to disobey Wu Zhi's order, after all, in the here and now, Wu Zhi is the highest military commander of the Left Route Army! Everyone had to leave in confusion, return to the army to announce the mobilization preparations before the battle, arrange for men to patrol the night and keep watch, and then rest and wait for the next day.

On the fourth watch of the next day, 100 escorts were called up by Lin Chong to bury the stove and cook, everyone got up at the fifth watch, had breakfast, wrapped the horse's hooves in cloth, and the cavalry generals gathered their teams and set off quietly during the sixth watch, Wu Zhi also led the Red Guard Battalion to cross the mountain beam of Tiandu Mountain, quietly sneaked into the northwest foot of Tiandu Mountain, and quietly lurked at a place of more than 30 meters near the enemy camp, waiting for the cavalry to surround the enemy camp.

After two tea sessions, Wu Zhi was condescending, and saw from a distance that the cavalry in the northwest had surrounded the southwest and north gates of the enemy camp, so he motioned to the soldiers of the Red Guard Battalion to take off the bamboo grenade on their waists, take out the fire fold they were carrying, blow off the flames, and light the grenade in their hands.

The condescending throwing, that called a quasi, the thunderous explosion burst out in an instant, and the enemy camp was instantly blown up, and chaos abounded. The tent of the enemy camp was blown to the ground in an instant, the flames soared into the sky, the smoke of gunpowder rose everywhere, and the screams and wails suddenly filled the sky, and the party members were completely frightened by this earth-shattering explosion. The cavalry in the northwest guarding outside the enemy camp was also silenced by the faint sound of explosions.

After Wu Zhi waited for everyone to throw a round, he immediately led everyone to rush down again, and after approaching the enemy camp, Wu Zhi signaled everyone to throw another round of grenades, and the grenades that fell from the sky like a divine thunder exploded in the enemy crowd, and the camp tent flew over, and the party members fell one by one, with broken hands and feet, blurred flesh and blood, and lay down miserably.

In an instant, Wu Zhi led the soldiers of the Red Guard Battalion to rush into the enemy camp by taking advantage of the chaos, and Lin Chong, Wang Jin, Sun Qi, Li Tingliang, Suo Chao, Li Zhenguo, Si Fangguo and others took the lead, and while leading the crowd to charge, they threw grenades into the crowded places and camp tents.

Seeing such a tragic situation, the party members suddenly collapsed as if they had been punished by the thunder god, and all the soldiers did not care about the command and dissuasion of the generals, and they did not have the heart to resist the Song Dynasty soldiers who rushed into the camp like divine soldiers descending from the sky, and they all began to run frantically outside the camp in panic, and the entire camp was scattered and collapsed.

Wu Zhi saw that the party members had fled in a panic, so he ordered the army to stop the attack, leaving only a dozen or so soldiers behind the fleeing party members, while intermittently throwing grenades into the fleeing party members, one after another loud noise, which further aggravated the collapse of the enemy camp, and the party members fled outside the camp gate like a torrent, and countless people were trampled on. The rest of the Red Guard Battalion soldiers, under the leadership of Lin Chong, Wang Jin, Sun Qi, Li Tingliang, Suo Chao, Li Zhenguo, Si Fangguo and others, began to clean up the battlefield in the back.

Liu Zhongwu, Chong Pu, Wang Sunchen, and other cavalry officers and soldiers who were guarding outside the camp gate were still wondering where the loud noise came from, and suddenly found that the door of the enemy camp was wide open, and the party members were shouting and crying frantically pouring out of the camp gate, panicking, and many people did not even have time to hold weapons in their hands, but just ran out with their belts in their belts.

After Liu Zhongwu, Chong Pu, Wang Sunchen and others gave the order to attack, they urged their horses to rush quickly to the party members who had fled and had no fighting spirit, and harvested the heads of the party members like cutting leeks. The entire battlefield was a one-sided massacre, with countless enemy casualties, as tragic as Shura's hell. The generals in the party army were also carried out of the camp by the fleeing crowd, some could not find horses to run, some even led the horses but did not have the opportunity to get on the horse, the bright armor became the focus of the Song Dynasty cavalry, the dead and wounded, many of them were captured without a little resistance.

More than two hours later, Liu Zhongwu, Chong Pu, Wang Sunchen and others led the cavalry to chase the party people out of ten miles away, and then Ming Jin collected his troops and turned back to clean up the battlefield. On both sides of the road and in the fields, there were corpses of party members, some of whom were seriously injured and did not die, but they were also killed one by one by the cavalry of the Song Dynasty who cleaned the battlefield, and countless party members were captured or surrendered.

When Liu Zhongwu, Chong Pu, Wang Sunchen and others rushed back to the party camp, they found that except for the Red Guard Battalion who Wu Zhi had brought down the mountain, there was not a single party member in the camp, and the entire camp was filled with gunsmoke, a mess, and it seemed empty, and some of the party soldiers who had been seriously injured by the grenade had been hacked to death by the Red Guard battalion soldiers one by one. Wu Zhi was leading the Red Guard Battalion to extinguish the fires in the camp, counting the property, grain, grass, cattle, sheep, horses and weapons that the party members in the camp did not have time to take away when they fled.

"What weapons do you use? So powerful! Liu Zhongwu couldn't hold it anymore and approached Wu Zhi and asked. The generals in the northwest also felt terrified when they saw the tragic situation of the enemy camp, and they also wanted to know what kind of weapons the Red Guard camp used to blow up the enemy camp so badly that the party members fled in such a panic.

"Oh, use this! It's a grenade! Wu Zhi took out the bamboo grenade on his body and handed it to Liu Zhongwu.

Liu Zhongwu took the bamboo grenade in Wu Zhi's hand and looked at it over and over, but he couldn't see how famous he was. Isn't this just an ordinary bamboo tube? Liu Zhongwu and the generals in the northwest were even more puzzled, and they couldn't figure out how this small bamboo tube could have such amazing power. Everyone has seen firearms, but we have never seen such a firearm.

Seeing the puzzled looks of the generals in the northwest, Wu Zhi didn't bother to explain, put away the grenade, and continued to command everyone to clean up the battlefield.

After counting, it was found that the entire campaign took less than three hours, and the results were remarkable. More than 40,000 enemies were killed, the enemy was wounded, more than 1,000 people were captured, and more than 3,000 people surrendered. At the same time, more than 10,000 war horses, more than 100,000 cattle and sheep were seized, countless grains and grasses, and countless goods were seized. However, the Northwest Left Route Army suffered more than 200 casualties, and only more than 80 people actually died on the battlefield, and more than 100 war horses were damaged.

Seeing the results of the post-war statistics, Liu Zhongwu and the cavalry generals such as Chong Pu and Wang Sunchen were surprised and unbelievable. Wu Zhi, Lin Chong, Wang Jin and other people in the Red Guard Battalion also felt incredible, the whole battle was too easy and smooth, and the results were too amazing!

Before the war, everyone originally questioned Wu Zhi, thinking that he had no hair on his mouth and was not able to do things firmly, a bit of a child's play, blind command, and was very worried about the outcome of the battle. But who knew that he led the Red Guard Battalion to mess up, and instantly scattered and disrupted the enemy army, giving the cavalry an opportunity to expand the results of the battle, and the battle was surprisingly smooth, and the results were exceptionally brilliant! Now, all the soldiers in the northwest have put away their contempt and doubts, and they are full of awe when they look at Wu Zhi like a god.

In this battle, the Red Guard Battalion can be said to have made the first contribution!

As soon as he entered the battlefield, he made great contributions, and Lin Chong, Wang Jin, Sun Qi, Li Tingliang, Suo Chao, Li Zhenguo, Si Fangguo and others were especially happy. Moreover, it is commendable that only a few dozen of the officers and men of the Red Guard Battalion were injured, and no one died.

Until this time, except for Wu Zhi, all the officers and soldiers of the Red Guard Battalion were still in a dream.
