The Cangshan Mountains are lined with ridges, composed of nineteen peaks rising from the ground from north to south, like a winding dragon crawling on the shore of Erhai Lake. Therefore, it is located in the lower pass at the southern end of Cangshan Mountain, also known as Longwei Pass. Located at the north end of Cangshan Mountain, Shangguan, also known as Longshou Pass.

Under the leadership of Wang Bi, the soldiers of the Ming army took advantage of the night to climb the wood to help the cliff, and the hardships and dangers during this period did not mention. But they once again created a miracle and conquered the thousands of walls of Diancang Mountain!

When the sky was bright, the 5,000 Ming army had been marching through the Cangshan Mountains for a long time. At this time, they finally saw the true face of this lofty mountain.

As far as the eye can see, the mountains are full of green forests, but the top of the mountain is covered with snow. The snow that melts from the top of Cangshan Mountain and the canyon in the mountain converge into spectacular waterfalls.

And the mountains are full of clouds and mist, the clouds are changeable, the clouds are scattered, for a while it is as light as light smoke, and for a while it is like black ink, and the soldiers who see it are amazed, as if they are in a fairyland.

"Let's go." Wang Bi had no intention of appreciating this strange scene, and urged the troops vigorously. Because he was late.

According to the plan, this Ming army should arrive at the Xieyang Peak behind Shimonoseki Castle before dawn, and suddenly kill after the army attacks the city, causing chaos.

However, whether it is Lan Yu or Wang Bi, when making plans, they didn't expect that the climate of Cangshan Mountain was very different and unpredictable from the bottom of the mountain.

When they set out last night, they watched the stars at night and were sure that it was a sunny day. As a result, after going up the mountain, a sudden strong wind blew in the middle of the night, and the soldiers who blew were staggered, unable to distinguish between north and south.

Then it rained heavily, making the already rugged mountain road even more difficult. Although the soldiers of the Ming army had done their best, they still arrived an hour later than planned.

When they crossed the mountains and mountains, overcame many dangers and obstacles, and finally came to Xieyang Peak, they heard the southern foot of the mountain slope shouting to kill the heavens.

When the soldiers heard this, they hurriedly used their strength to eat, climbed the Xieyang Peak and saw that there had been a fierce battle for a long time in front of the Longwei Pass.

"Quick!" Wang Bi anxiously urged the soldiers to quickly cut down the bamboo poles and hold up all the banners he brought. Then the drum beat desperately, and the horn sounded again.

In the midst of the earth-shattering drums and trumpets, he drew his sword, pointed to the dragon's tail at the bottom of the mountain, and shouted, "Children, follow me!" ”

After speaking, he led 5,000 Xuan Feng and rushed towards Xiaguan like a fierce tiger on the mountain......

~~

To the east of Shimonoseki, Lan Yu was already commanding the main force to attack the city.

The first thing to solve is the wide Erhe River under Xiaguan City. To this end, Lan Yu ordered people to build a number of bamboo rafts in advance and threw them into the river side by side one after another.

Holes are left in the four corners of each bamboo row, and all adjacent bamboo rafts are tightly tied with iron chains, and a spacious pontoon bridge is built little by little.

And what was used to cover the sappers to build the bridge was the artillery unit that made its debut in the Battle of Yunnan. During the time when the blue jade army was in Weichu City, one was to rest and recuperate, and the other was to wait for this army to come and converge.

Originally, the Ming army did not have artillery suitable for field battles, especially in the mountains of Yunnan, and the heavy artillery was definitely a nightmare for the baggage troops, so the generals had no idea of fighting artillery at all.

However, this attack on Dali, whether it is from Shangguan or Xiaguan, must face a high-walled, thick-walled, solid and perfect city defense system. In order to reduce the casualties of the siege troops, Lan Yu listened to the advice of His Royal Highness the King of Chu and waited until the first mountain artillery team of the Ming Dynasty arrived before marching to attack Dali.

When the abseiling system was first designed, Lao Liu also wanted to design a mountain cannon for the Ming army. Over the years, under his care, the Ming Dynasty's artillery industry has grown by leaps and bounds, and the manufacturing capacity is not what it used to be.

Mountain guns, on the other hand, were required to be lightweight, small, easy to transport, and powerful at the same time. This requires two conditions and one card, and all the artillery used by the sailors is not suitable. Even the lightest bowl cannon was too heavy for mountain warfare.

Fortunately, it was difficult for His Royal Highness the King of Chu to be difficult, because he thought of Qi Jiguang's tiger squat cannon. He remembered that Qi Jiguang's original intention of inventing the Tiger Squat Cannon was similar to his own, and it was because he had to deal with operations in mountainous areas, forests, paddy fields and other areas where the cannon could not be maneuvered, so he invented this light and powerful artillery.

The style of the Tiger Squat Cannon is also very simple, the body of the gun is only two feet long, but the inner diameter of the muzzle is three inches, it belongs to the short-bodied straight-barreled large-caliber artillery, in fact, it is the world's first mortar officially equipped with the army.

Qi Jiguang's tiger squat cannon was made of wrought iron, and in order to prevent the bore from exploding, seven iron hoops were added around the body. The head of the gun is erected by two iron claws, and there are iron stumbling, with a total weight of 36 catties. An animal can be moved. When necessary, the soldier can march with a cannon on his back, and it is very light.

The old six cannons are all copper, so there is no need to worry about blowing up the bore, so seven iron hoops are saved, so the weight of the 'Type 6 Tiger Squat Cannon' has been further reduced to less than 30 catties, but the firing range is farther than the iron cannon.

~~

Yu Min belonged to the siege troops, and at this time he was standing in the queue at the rear of the position, looking curiously at the tiger squatting cannons in the front row and the busy artillery with his comrades.

The artillerymen were busy digging pits and erecting tiger squat guns.

Because the recoil of the mortar is very strong, before firing, it is necessary to dig a pit in the ground, sit the tail of the gun in it, and then fix the gun body to the ground with a large iron nail. The muzzle of the cannon is high, and the shape is like a tiger squatting, so the name of the cannon is 'tiger squatting'.

Once the gunners had positioned their guns, they began to reload them with their hands and feet.

I saw that they first inserted the medicine thread and bound it with cloth; Then six or seven taels of gunpowder were loaded and covered with a wooden horse. Then fill in a little dry soil from the muzzle of the gun, put in a hundred pieces of lead weighing five coins, and then build a few times with soil. This is to keep the muzzle airtight in order to increase the power.

Finally, a large lead bullet weighing thirty taels was pressed to the top, and the loading was completed.

At the officer's order, the gunners lit the fuse with the arquebus, then covered their ears and took a few steps back.

Seeing this, the experienced veteran quickly covered his ears and opened his mouth, only Yu Min, a rookie who had never seen a cannon, was still looking at it stupidly.

saw a flash of fire from the muzzle of the cannon, and a deafening cannon sound sounded on the position, and the frightened Yu Min sat on the ground with his head buzzing. What Niu Zongqi said to him next to him, he couldn't hear a word clearly.

It wasn't until Niu Zongqi pulled him up from the ground and slowed down for a while that he regained his sense of hearing.

It was so miserable for onlookers to shoot artillery, let alone the targets that were bombarded.

The Dali army at the head of Xiaguan City had never seen a cannon, and before the cannon rang out, they all stood on the wall of the Great Wall, desperately throwing stones at the Erhe River, trying to prevent the Ming army from erecting a pontoon bridge.

When it was smashed, the cannon rang out, and the Dali army did not know how to dodge. In the blink of an eye, he was shot down......
