The 3,000 men and horses, half of which were Xue Dongting's guards, and half of Shi Dekai's battalion, under the continuous bombardment of the four cannons, crossed the ditch in a disorderly manner, and assembled in a chaotic formation at Yukou.

As a result, there will be no generals, no soldiers will be found, and the entire battalion will be in disarray.

The other party came faster than expected, arriving in only two quarters of an hour, and it was evident that it was coming in a hurry, and it stopped a mile or two away, and then dozens of artillery pieces were brought up from behind.

That's right, dozens of guns.

Among them, there were twenty cannons, all equipped with gun carriages, which were pulled by two mules, and some were pushed behind, and the speed of travel was very fast.

There are as many as forty or fifty small Francophone machines and tiger squat cannons, and there are one or two hundred bird guns that do not use arquebuses, which are densely placed in front of the formation.

As soon as they saw these artillery, Xue Dongting and Shi Dekai's faces changed greatly, and their subordinates were also in a commotion.

None of them had fought any major battles, and it was the first time they had seen so many pieces of artillery.

They did bring some artillery, but they were all small Francos and Tiger squat cannons, and there were some old generals' cannons, second generals' cannons, and attack artillery, all of which had been stored in the Zhenxiwei arsenal for an unknown number of years.

The only cannons that can be used are the two five-foot Franc cannons that Shi Dekai can shoot a mile away.

But the distance of the opponent's array is more than a mile, and I don't know if the two Francophiles can hit it.

Xue Dongting and Shi Dekai couldn't care so much, so they hurriedly asked people to reload the two Franc planes, adjust the angle of the longest range, and wanted to take advantage of the fact that the opponent's formation had not yet been set up, and fire to seize the opportunity.

Two Franco-cannon guns rumbled, and two shells whizzed away.

Xue Dongting and Shi Dekai's eyes widened, and their three thousand subordinates also widened their eyes, wanting to see where those two cannons could hit.

To their disappointment, the two shells did not hit the other side, and only landed thirty or forty paces in front of the opponent's formation.

The artillery in front of the opposing formation seemed to be taken aback, and they squatted behind the artillery carriage, and after seeing that the shells missed, they stood up again and continued to fix the cannons.

"Quick, push the cannon up fifty paces, quick!"

Xue Dongting remembered shouting and urging the artillery of the two Furlong cannons to move forward.

Several artillerymen hurriedly picked up the iron rods and pried up the iron drills that were fixed on the ground.

Before they could push the gun wagon, gunpowder smoke rose from the artillery on the opposite side, and with the rumbling sound of cannons, more than 20 shells pierced the sky and smashed into the array of officers and soldiers at Yukou.

Suddenly, the terrible screams resounded throughout the sky.

The whole army was in an uproar again.

"Don't mess around! Don't mess around! ”

Xue Dongting waved the waist knife in his hand and scolded loudly.

Shi Dekai on the side said with a pale face: "Lord Xue, withdraw the troops, how much can you run." ”

"Withdrawing troops?" Xue Dongting frowned, "I'll wait ......"

As soon as he spoke, another burst of artillery was heard on the opposite side, and ten more shells whistled, which was another cannon fired by the Franc machine, which was extremely fast.

When ten shells penetrated the formation, dozens more casualties were inflicted.

"Underestimate the Qin thief." Shi Dekai shook his head and sighed.

"I didn't expect this guy to have so many artillery, and I didn't expect him to go all out to defend the Xuanda friendly army, transfer so many artillery pieces and troops to Lancheng, and take the initiative to attack."

"Lord Xue, I will only be beaten when I stand here, and I will face dozens of artillery pieces and hundreds of birds and guns when I rush over, this battle has no chance of winning, and if I don't leave, it will be too late."

Xue Dongting's face struggled and hesitated.

He couldn't wait to peel off the skin of the dog thief surnamed Qin, but he didn't want to let go of this opportunity.

But the current situation ...... Shi Dekai is right, the battle is bound to lose.

Struggling for a moment, when the third round of artillery bombardment arrived, Xue Dongting sighed hatefully and shouted, "Withdraw your troops!" Withdraw troops! ”

Hearing these two words, he and Xue Dongting's subordinates turned their heads and ran away, and nearly three thousand people crowded together and fled back in a swarm.

On the other side, Luo Daniu saw that the other party was defeated, and immediately drew his weapon and shouted: "Get on the horse and chase!" ”

As he spoke, Luo Daniu and Liu Youzhu took the lead in stepping on their mounts and chasing after them, followed by more than 2,000 people who first boarded the camp and the Wudang camp, and the rest stayed behind to take care of the baggage and artillery.

Xue Dongting and Shi Dekai can be described as a thousand miles away.

Of the 3,000 subordinates, those who died, those who surrendered, those who fled, and those who fled with them finally fled back to the city of Qilan, less than 500 people.

Luo Daniu and Liu Youzhu chased straight to Lan City, and then surrounded the three city gates, leaving only the west gate unsurrounded.

Then, the two sent a part of their troops to block the transportation arteries of nearby villages and towns to prevent the gentry in nearby villages and towns from transporting grain, and also try to block the leakage of news.

The troops who remained behind cleaned up the battlefield all the way, carrying artillery and baggage to join them, and the four big Franc cannons on the ditch pier platform on the wall also arrived.

The day after the good news of Zhaishanggou was transmitted back to Lancheng, 1,000 reserves, 500 construction teams and 2,000 people, who had already been prepared in Lancheng, transported the reinforced concrete to Lanzhou.

This huge convoy consisted of 500 mules and horses, 1,000 chicken carts, and 500 horses and mules.

The reserve force had to go to the various towns and villages that had been captured, but the construction team was not going to rebuild the city, and the fortified city did not need to be rebuilt for the time being.

They first carried the reinforced concrete to the north, and after the Guan Emperor army captured the area of the Inner Great Wall, they went to rebuild the Limin Fort and the Laoying Fort on the edge of the Inner Great Wall, which were connected with the Inner Great Wall as a whole, and were an important fortress to guard against the Ming army of Datong Mansion.

Therefore, even if the road is long and the transportation cost is huge, Qinchuan insists on letting people transport the reinforced cement over, and take local materials there, and sand and quarrying can be built directly.

Luo Daniu and Liu Youzhu are the main attacking forces in the entire northwest strategy, and Lanzhou is also the main direction of attack.

Qin Chuan provided them with four Tianwei General Cannons, ten Red General Cannons, ten Big Franc Machines, Little Franc Machines and 50 Tiger Squat Cannons, a total of 74 artillery pieces, as well as 200 flintlock guns and 20 rifled guns.

Among them, the four Tianwei general cannons and the ten red-clothed general cannons are extremely powerful, and they are the main artillery for the siege.

Despite the powerful artillery, Luo Daniu and Liu Youzhu still did not dare to take it lightly when facing Lan Cheng.

It is a majestic military town.

The whole city circumference is as long as seven miles, the city wall is covered with bricks, up to three zhang and eight feet, the four city gates are all built with urn cities, there is also a moat built outside the north gate and the east gate, there is also a wide and five zhang outside the city, the unfathomable moat, there are bridge piers built only outside the four city gates, and the suspension bridge is hung on the city gate.

Attacking such a city is not an easy task.

Luo Daniu and Liu Youzhu were not in a hurry to attack the city, but camped outside the city, and sent 1,500 troops, carrying some artillery and flintlock guns, to attack the nearby villages, and first get the grain and silver of those gentry clans.

The other 1,500 troops who remained gathered wood everywhere and began to build large siege engines.

They would not attack the city until the soldiers and horses who had attacked the nearby villages returned.

In the entire Northwest Raider, Qinchuan has to face the important towns of Ningwu Pass, Yatou Pass, Qilancheng, Hequ City, and Baode City, among which the most difficult to fight are Ningwuguan and Qilancheng.

As long as they can take Lancheng, Luo Daniu and Liu Youzhu will divide their troops into two routes, and drive all the way up to the partial pass, and there are several towns and military forts on the way to worry.

The other way will turn to the west, join forces with Feng Yilong to attack Baode City, and then go north to attack Hequ City.

On this side of the inner Great Wall, it was handed over to the main forces of Qin Chuan and Li Dingliang, first hit Ningwu Pass, and then advanced northwest along the Inner Great Wall, taking Shenchikou, Yijingtun Fort, Limin Fort, Octagonal Fort, and Daworming Fort.

Now, Qin Chuan is leading 3,000 Guan Emperor troops and 1,000 reserves to be stationed in Ninghua Qianhusuo, and Li Dingliang is leading another 1,000 trap camps and 1,000 reserves to garrison Jingle City.

Qin Chuan's 10,000 troops have already poured out, and even most of the reserves have been dispatched.

Lou Fu Black Mountain Fort only left 2,000 reserves, and they had to support and assist in the defense of Fangshan Fort and Luyukou Fort at any time.

In the past few months, Chen Zhan has worked day and night to build 12 Tianwei General Cannons, and the number of Red General Cannons has also exceeded expectations, reaching 33, 50 Big Franc cannons, and more than 230 Little Franco and Tiger Squat cannons.

Li Xuejing's gun factory also worked day and night, and built a total of 700 flintlock guns, but the production capacity of rifled guns was very low, and less than 60 rifled guns were made in the past five months.

Today, the remaining eight Tianwei military cannons are all placed in Ninghua Qianhusuo, as well as twelve red-clothed general cannons, 20 big Fran machines, 60 small Franco machines and tiger squat cannons, 300 flintlock guns, and 30 rifled guns.

Jingle City has two Tianwei General Cannons, four Redcoat General Cannons, ten Big Buddha Lang Machines, 40 other small cannons, 100 flintlock guns, and only 8 rifled guns.

The reason why the heavy firepower is placed in Ninghuasu is because Jingle City is still very safe for the time being, and Ninghuasuo will bear the brunt and will be besieged by the main force of the Ming army.

The fort has been rebuilt, with a reinforced concrete frame structure poured on the basis of the original city wall, and a hollow reinforced concrete city wall has been added to the city wall, so that the city wall reaches a height of three feet and three feet.

Now, the main force of the Ming army has surrounded Ninghua tightly.

A total of 35,000 Ming troops, more than a dozen generals and guerrilla generals from Xuanda and Da, the main will be the new Datong general Wang Pu, and the supervising army is Lu Jiude, Wang Dehua, and Wang Kun.

He Sheng and Zeng Caofei, who had suffered defeats under Qin Chuan before, were also listed, as well as the two eunuchs who supervised the army, Wang Dehua and Wang Kun.

These people were also sent because they had some understanding of Qin Chuan's use of troops and the tactics of the Guan Emperor army under his command.

As the so-called road is narrow.

This time, these people repeatedly reminded Wang Pu, Lu Jiude and others not to underestimate the enemy.

also reminded again and again that the Qin thief's artillery was very sharp.

But they don't know exactly how sharp it is.

If Qin Chuan really shows his family background, it can make them startled.

Wang Pu and Lu Jiude did not dare to underestimate the enemy, and the 35,000-strong army had been pressing the border for two days, but they did not dare to attack the city, only built siege equipment every day, and gathered a group of generals to discuss countermeasures.
