At this time, the officers and men who were walking in the front felt that a rope had suddenly tripped under their feet, and before he could figure out what he had tripped up, he heard a huge roar suddenly erupt in front of the team, and a flash of light flashed from the ground in an instant, and a large amount of earth and stones were lifted out of the ground, including the bodies of several officers and soldiers in front of them, which were also lifted into the air, and when they fell, they had become broken pieces.

Even the officers and men who were not blown up were not much better, and a group of officers and men who were relatively close to the bombing point were suddenly overturned by the air wave and fell to the ground in all directions, and even some officers and men were shocked by the violent explosion on the spot, and their organs were torn apart and bleeding, and they were shocked to death on the spot.

It turns out that Liu Bao used the secret weapon "mine" made by Gao Chengxin here this time, in fact, the mine is not Xiao Tianjian's "creation", but someone in the Ming Dynasty invented this kind of thing, at the beginning of the mine was detonated with an open flame, put a clay basin on top of the powder barrel buried in the ground, which was filled with charcoal fire, when the enemy walked to the place where the mine was laid, pull the rope to pull over the clay pot containing charcoal fire inside the mine, and let the fire fall on the gunpowder to detonate the mine, but that kind of mine is too dangerous, If you are not careful, you will blow up the person who planted the mine, so it is said that in the era of Qi Jiguang, someone invented a kind of steel wheel fire mine, relying on the steel wheel to fire the spark, detonating the mine, for this emperor also personally watched the person demonstrate the effect of this mine, and even set up a special team in the Wanli period to be responsible for this.

However, later the mines were not popularized on a large scale, but Xiao Tianjian did not forget this kind of Yin people's big killing weapon, after the Xingtian Army developed the self-generated firecracker, he ordered Gao Cheng to use the flint mechanism of the self-generated firearm to develop mines, and now a batch of mines have been applied to the army.

This time, Liu Bao came to ambush Cao Wenyao, so he buried a few such guys on the road booked by Cao Wenyao, and the charge was very large, just triggering one, and killing a large number of officers and soldiers at once.

Liu Bao rubbed his ears and cursed loudly: "Grandma's! How much gunpowder did Zhao Si bury in this goods? almost deafened Lao Tzu's ears! Grandma's go back and settle the account for you! Call me! Don't let them go! Whoever killed Cao Wenyao, Lao Tzu personally asked for credit for him! ”

With his roar, all of a sudden, the sound of popping beans began to sound everywhere on the dark hillside, and the dark hillside was full of flickering firecracks, and puffs of green smoke rose in all directions on the hillside.

Hundreds of self-made fire guns slashed their heads and covered their faces, and during this time, some of the subordinates of the Xingtian Army shook the fire and lit one thunderbolt after another, and smashed down with their arms and struggles.

This time, these officers and soldiers led by Cao Wenyao were unlucky, the road was already very narrow, they were pulled into a line, and after the chaos, they were crowded together, no one could quickly escape from this dead place, the firecrackers of the Xingtian Army were almost like shooting targets, knocking them over one by one, and every thunderbolt explosion could overturn several officers and soldiers, and the officers and soldiers were crying for their fathers and mothers, scurrying at the foot of the mountain.

The sound of firecrackers continued to sound until almost dawn, and then stopped under Liu Bao's order, and a large number of Xingtian military personnel wrapped white cloths around their necks, rushed down the dirt slope and began to clean up the battlefield.

The whole hollow was full of corpses of officers and soldiers, and there was a strong smell of blood in the air, and the blood on the bodies of many officers and soldiers who had just been killed was still steaming, and they didn't understand until they died, why the thieves could fire without lighting the rope in the dark, and if the thieves lit the rope, why couldn't they find out in advance that the thieves were ambushing here, and let them go to death, and the thieves were outrageously angry.

But at this time, even if they can't figure it out, it's too late, more than a thousand officers and soldiers were almost killed here, and many were injured, and the rest of the living did not run away, and they all became Liu Bao's prisoners, and after dawn, someone ran to find Liu Bao and excitedly reported that Liu Bao had a good news, saying that Cao Wenyao had been found.

When Liu Bao followed his subordinates to the side of a corpse, and then in the light of the morning light, he looked down and saw a general in heavy armor lying on top of a small mound of earth, his whole body was covered with blood stains that were about to coagulate, and a war horse fell not too far from him, and the horse corpse was also full of bullet holes, obviously after Cao Wenyao found out about the ambush of the Xingtian Army last night, he wanted to turn his horse and escape, but because there were few people in the entire team on horseback, most of the Xingtian Army members aimed at their officers on horseback as soon as they fired, As a result, Cao Wenyao was shot several times and was killed here by people and horses.

Turning over Cao Wenyao's corpse, I saw that Cao Wenyao was still shouting something with his mouth open, his eyes were wide, and he seemed to have a trace of shock and unwillingness, and a huge blood hole was opened by a projectile in his neck, it was this shot that killed Cao Wenyao, and he grabbed a few prisoners to identify him, and they all confirmed that this person was Cao Wenyao, Liu Bao then ordered Cao Wenyao's head to be cut off, packed it in a box, sprinkled with lime and taken away from here, and the corpse made the captives bury in this place on the spot.

After dawn, Liu Bao left two teams of soldiers to guard these prisoners of war, clean up the battlefield, and immediately led his troops back to the mountain pass, at this time Li Yantian had already been waiting in the mountain pass to jump up and down, in the second half of the night in the north of the explosion, the sound of fire guns shouting and killing spread far away, even in the mountain pass area can faintly hear the explosion of a huge mine, Li Yantian concluded that Liu Bao must have won the battle this time, so before dawn he commanded the soldiers to come out and prepare for the battle, just wait for Liu Bao to come back and give the order to set off.

Although they waited all night, the soldiers and generals of the four battalions did not blink a night all night, and fought fiercely for more than an hour, and ran such a long way, but when Liu Bao led his troops back to the mountain pass, the soldiers and generals all seemed to be very energetic and did not show fatigue at all.

At this time, the officers and soldiers who stayed in the camp should have lined up to fight according to the original plan, and cooperated with Cao Wenyao, who went around to the back of the Xingtian Army, to attack the Xingtian Army, but the sky was bright, and a few soldiers who followed Cao Wenyao to fight fled back to the camp, and told the news of their ambush to the generals who stayed behind, and the news spread quickly among the officers and soldiers. The officers and soldiers who stayed behind guessed that Cao Wenyao was already more than lucky, where was the idea of going out of the camp according to the original plan!

As a result, it was almost noon, and he still didn't see Cao Wenyao come back, but he waited for the Xingtian Army, and the two battalions of the Xingtian Army Hulala rushed to the outside of the official army camp, and immediately erected a high pole, and hung a human head on the high pole, and the officers and soldiers with good eyes immediately saw this human head clearly at the camp gate, who could it be if it wasn't their Lord Cao's head?

So the remaining more than 3,000 officers and soldiers immediately became in turmoil, the commander is dead, who still has the heart to fight here! Although the deputy general who stayed behind also wanted to hold on, but He Naijun's heart was scattered, and he was powerless to return to heaven, seeing that the Xingtian army was about to set up a cannon outside to bombard the camp, the deputy general gritted his teeth and ordered to withdraw to Shaanzhou, and a large number of officers and soldiers immediately broke out of the camp and fled in the direction of Shaanzhou.

Originally, Liu Bao and Li Yantian were going to fight a tough battle against the official army camp, but before they could start to prepare for attacking the camp, they saw a large number of officers and soldiers coming out of the camp from the other side of the camp, one by one like rabbits spread their legs and fled towards the direction of Shaanzhou. So he simply ran forward, leaving behind a large number of officers and soldiers crying and shouting at the back, what weapons, soldiers' tents, baggage and grain, all became floating clouds at this time, all the officers and soldiers were tendoned, just thinking about fleeing quickly.

Liu Bao and Li Yantian looked at this scene, their mouths opened wide, and in the end, the two of them nodded, waiting for a fart! Kill! So the battle formation also became a floating cloud at this time, except for the artillery who could not lose their cannons to catch up, the rest of the people who were in an uproar followed their respective officers and chased them out.

Good guy, this battle can be regarded as chaotic enough, Li Yantian and the generals of the reserve battalion of his battalion actually ran in front of Liu Bao because they did not consume physical strength like Liu Bao's first battalion, one by one as if they had been beaten with chicken blood, screaming excitedly, chasing after those fleeing officers and soldiers, and almost chased to the city of Shaanzhou in a daze, if it weren't for the fact that the defenders of Shaanzhou had sent a sentry horse out to meet the rout, this guy really dared to lead the troops to chase into Shaanzhou City in one breath, but even so, The officers and soldiers in Shaanzhou were also frightened, and they began to fire artillery from afar, not caring at all about those who could not beat the Xingtian army.

Fortunately, Liu Bao still maintained a trace of restraint and sent someone to catch up with Li Yantian and ordered him to collect his troops and withdraw to Mianchi.

After going back, Liu Bao and Li Yantian took stock of the seizures, and packed up a lot of food in the messy armor and soldiers' tents, and had to temporarily recruit a lot of people from Mianchi County, so they pulled the seized things back to Mianchi County.
