Li Xiao made arrangements for the Tang army in the southwest in advance, which was very effective in preparing for the future.

As Li Xiao expected, after Li Xiao's policy of replacing land and returning to the land, there were as many as twenty chieftains rebelling in the four provinces of Yunnan, Guizhou, Guangxi and Sichuan.

Among them, the more than ten local chieftains who had the largest army, the widest territory, and had never been convinced by the Tang army, almost all rebelled. However, one-third of the small and medium chieftains who had been neutral with the Tang army and requested to change their territory and return to the land within one year rebelled. As for the small chieftains who had a good relationship with the Tang army and had not received the order to change their territory and return to the land, there was no one in the rebels.

If Li Xiao's measures to change land and return to the land before the Daxi Kingdom was destroyed and there were many remaining Ming troops in the southwest, Li Xiao's measures to change land and return to the land would not be so fierce. Now, the southwest region has been completely pacified, and Dashun in the north has signed a peace agreement with himself. Li Xiao, who has an absolute advantage in troops, of course, must seize the opportunity and catch them all in one go.

Li Xiao immediately ordered the Tang army troops who had already prepared were dispatched immediately to strictly eliminate any of the major rebel forces.

After all, among the four provinces, the most powerful chieftains have only more than 3,000 troops, and the rest are just a thousand men. Their equipment and weapons are also very primitive and simple. Therefore, for the Tang army, which has strong troops and elite equipment and a large number of artillery, this pitiful chieftain soldiers are really not enough to be stuck in the gaps.

At the same time, Li Xiao also demanded that after the rebellious chieftains had eliminated all their troops from the mountains where they were stationed, all of them were sent overseas, and then they were dispersed and resettled in various places to completely eliminate their remnants of the remnants. The land in the air allowed Han people from the four provinces to settle in and receive them, thus completely changing the local ethnic composition and achieving long-term stability and permanent peace.

Soon, good news came from all over the southwest, and the chieftains and horses from all over the country were almost defeated in front of the Tang army's advance and begged for surrender.

Even if some brave men wanted to defend the village, their simple defense measures were vulnerable under the heavy artillery of the Tang army and were quickly destroyed.

Therefore, Li Xiao, who frequently received good news from these chieftains, no longer cared about his rebellion. Now he is focusing on a brand new thing in this era.

This is the Minnie Bomb, who has made a big splash in time travel novels.

The Minnie bullets in history were designed to solve the embarrassment that the accuracy and rate of fire cannot coexist. In the 19th century, around 1849, this problem that plagued the manufacturing of the front-loaded rifle for hundreds of years was solved by a clever French captain Minnie in a very simple way - this is the Minnie bullet.

The so-called Minnie bullet is actually a kind of expanded bottom-enlarged bullet. The diameter of its bullet is also smaller than that of the barrel, and may even be smaller than the round bullet. This way, it is very convenient to load and can be easily stuffed into the barrel to ensure that there is no bullet stuck.

The bottom of the Minnie bullet is not round or flat, but a conical or cup-shaped hole is left at the bottom of the bullet when casting. The edge of the hole is thinner lead. When black gunpowder is poured into the chamber, the cup-shaped hole of the Minnie bullet will naturally cover the gunpowder.

When the rifle fires, the black gunpowder expands rapidly, and before pushing the bullet, it will first open the lead of the Minnie bullet's bottom. At this time, the expanded Minnie bullet's bottom will automatically close to the barrel and bite the rifle, and force the bullet to rotate.

In other words, the emergence of Minnie bullets solved the problem of difficulty in loading a front-loaded rifle gun and the accuracy of the smoothbore gun is too low, perfectly combining the two advantages of the front-loading gun and the rifle gun in the pre-loading era. The front-loading gun using Minnie bullets has a general level of shooting speed, and at the same time it has the range, accuracy and power of the rifle gun.

Such improvements made the power and effect of the rifle exceed the artillery at that time and became the decisive weapon on the battlefield at that time. What Li Xiao was most interested in was this range - up to 300-500 yards, and the maximum range was about 450 meters, which can be converted to more than 600 steps.

Until the Napoleon period, the smoothbore cannons of that era had an accurate range of only 300 yards. In other words, although infantry using Minni bullets were still severely killed by artillery when they formed a dense phalanx, they could approach the precise location within the range to kill artillery. This feature caused a huge transformation in the design of the artillery, and rifled cannons began to appear, and kicked the smoothbore cannons out of the battlefield in one fell swoop after the Crimean War and the American Civil War, making the rifled cannon completely replace the smoothbore cannons.

In fact, the power of the Minnie bomb is more than that. The result of its appearance is that it directly forces the dense quadratic arrays of infantry in the Napoleon era and the dense linear queues to be completely disbanded.

Of course, it is just a disbanding of the square formation, and the strait shooting line must be retained. After all, this is just a front-loading gun, and you must stand to load bullets. It only has about 3 firing rates per minute. The essence of queuing and shooting has not changed, but the lethality and killing range have increased greatly.

Before the 1850s in the 19th century, whether it was the Napoleon era, the Gustav era, or the Spanish phalanx era, even though European countries knew that cannons killed extremely dense queues, the range of flintlock rifles was too short, so they knew that they were tiger's mouths before, but they still had to line up in square formations to kill them. This tactic has lasted for more than 300 years since the invention of the mesh gun.

But when the Minnie bomb appears, the range of the rifle is increased to 500 yards in one fell swoop, which is an increase of 5 to 10 times. The dense quadratic array immediately becomes meaningless - you don't have to wait for enemy artillery to kill you, and the infantry can use the Minnie bomb to shoot you for a long-range shot.

It was the emergence of the Minnie bomb that completely retreated from the battlefield for the infantry phalanx that had lasted for two thousand years since ancient Greece.

However, the Minnie bomb was not very famous because it appeared too late. The mid-19th century happened to be the era of great technological development. At the same time, things like breech striker guns appeared, so the glory of the Minnie bomb was quickly covered up.

But at present, it is the best weapon: because the Minnie bomb is very easy to use, it has lower technical requirements than rifling, and it does not even require a machine.

Generally, round bullets for casting muskets are made of an iron mold, poured into melted lead into lead bullets. This mold is so small that it can be carried in your pocket. Generally, it is directly distributed to the infantry with a mold and a few kilograms of lead, so that the infantry can use the campfire to molten lead to cast bullets for the next day when they are camping for supper.

Of course, it is also feasible to distribute lead bullets on a large scale in normal scale. However, because the lead is relatively soft, it is easy to deform due to collisions during placement and marching. Generally, it is a habit to let soldiers cast temporarily before the war.

The Minnie bomb is just to change the casting shape inside the iron mold. Therefore, it has no technical level. Just this simple action can increase the effective range by nearly 4 to 5 times.

In fact, it not only increased the range. It also increased its power and reduced the amount of gunpowder.

The reason is very simple. When the musket leaves a large amount of gaps on the round bullet, a lot of gunpowder leaks out and is wasted, rather than being used to push the bullet. The expansion bottom of the Minnie bullet can completely seal the barrel and greatly increase the utilization rate of gunpowder. Therefore, gunpowder can be filled less and has the same or even higher power.

With less gunpowder, the chamber pressure will naturally decrease. In this way, the newly released barrel can be made thinner, and the recoil is also reduced, which is more conducive to aiming. In addition, because Minnie bullets are pointed or long bullets, their mass can be made larger than round bullets at the same caliber. This means that while maintaining the mass and power of the warhead, the caliber can be reduced, and the barrel can be shortened while maintaining the diameter. In addition to reducing weight to the barrel, this can also increase the penetration of the bullet to achieve a better and better killing effect.

However, Minnie bullets do not necessarily need to be as heavy as round bullets or heavier as round bullets. Because of the advantages of sealing and rifling, it has a higher initial velocity, power and range. In other words, large caliber is no longer needed. While reducing the barrel caliber, bullet weight and gunpowder loading, it can maintain a larger range and stronger power. The rifle and bullets are both lighter, which means that the load of infantry is greatly reduced.

As for the actual tactical performance, let alone. According to the test of the existing Shuelumi gun of the Tang army, its effective range is rapidly increased from 120 steps to 400 steps to 450 steps, even if the initial shooting speed remains unchanged, the number of shootings can be increased to nearly 4 times. This means that the Shuelumi gun used by the Tang army now has greater lethality and more hit times, and it can also have a greater possibility of confrontation, especially when fighting against cavalry.

Because for cavalry, the so-called battlefield charge is not to rush all the way to the end. Given the need to maintain horsepower to enable cavalry to obtain the maximum impact, European cavalry during the Napoleon period generally started to charge at a distance of 200 to 300 yards from the enemy (sword unsheathed, small steps forward), and quickly advanced at 150 yards from the enemy, and only started to charge at full speed at 50 yards. In the East, Mongolian horses were relatively small in size and had high endurance, but their charge speed was relatively low, so they usually started to prepare for charge within 50 meter/150 meters.

If the Minnie rifle is used, then when fighting against the Qing army and horses, the infantry can open fire on the Qing army before it is ready.

If the Qing horse team starts charging at full speed outside a distance of 500 meters, it will consume a lot of horsepower. The Mongolian horse is already relatively small and the cavalry needs to wear armor, so the charge distance has a great impact on the horse's physical strength. Therefore, if the new long-range rifle using Minnie bullet is put into the battlefield, it will greatly reduce the combat effectiveness of the Qing cavalry.

When siegeing, Minnie rifles can even suppress the city head outside the city crossbow machine and artillery, greatly reducing the difficulty of siege. More importantly, Minnie bullets have a armor-piercing power far more than traditional round bullets. Even if a general wearing heavy armor is used, there is no way to block his shooting within a hundred steps. In this way, it will become more difficult for the enemy to defend at the city head, and the soldiers guarding the city will be eliminated more easily.

Therefore, after receiving the news that the Ordnance Institute developed the Minnie bomb, Li Xiao was very happy and rewarded the relevant designers.

Because its appearance is perfectly in line with the current large number of Suifou Lumi guns equipped with the Tang army. In fact, its range and power are greatly improved, but there is no need to re-dress on a large scale. It is really a very timely, efficient and powerful new invention.

Li Xiao immediately ordered the ordnance factory to produce similar lead-for-support casting tools, and then distributed them to various military towns to replace the existing lead-for-support casting tools. Within a few months, all the casting tools were replaced. From then on, they completely bid farewell to the era of round-ropes, and the entire army began to widely use Minnie bombs.

Originally, Li Xiao wanted to produce rifled guns while the iron was hot, and even invented more powerful yellow explosives to replace black gunpowder, but considering that such work was too advanced, it was difficult to achieve the current processing accuracy and production methods. Therefore, he had to give up for the time being.

However, he still provided his ideas to the ordnance designers, allowing them to continue to explore at any cost and at the hope that in the future, these inventions that far surpass this era can be produced.

Just as Li Xiao was fully urging the Minnie bomb production, Li Guotai and Zhu Cixuan, who quietly sneaked back from Myanmar, returned to China, worked hard and dangerously, and finally arrived at the China-Myanmar border after nearly a month of hard trek.

Seeing the Myanmar pass ahead, Li Guotai showed a rare smile on his tired face.

It was not easy. The group pretended to be monks, sleeping in the open air, and walking on the roads. They almost exposed themselves several times, and were attacked by poisonous snakes several times. Fortunately, the group took care of each other and acted carefully. Finally, after going through hardships, they arrived at the Myanmar pass leading to China.

Among them, Zhu Cixuan, who was only eight years old at that time, should have worked hard and difficult, but he, who seemed to be gentle and honest, also has a strong and brave side.

Along the way, although his feet were covered with large blood blisters and had ulcers, the stoic child did not slow down his walking speed and followed Li Guotai eastward in silence. This made Li Guotai and others look at him with admiration.

Li Guotai and others hurriedly finished rations with three other people outside the gate. After a while of rest, they mustered up the courage to walk towards Myanmar Pass.

At this time, because the battle was in the Chinese border, there were very few clearance personnel. One or two people passed by in a long time. The Burmese soldiers guarding the pass were also lazy and looked bored.

As the leader, Li Guotai wanted to wait until a large number of people passed the level before going with them, but along the way, he never waited for the right companion. Seeing that it was getting dark, in order to prevent the Burmese soldiers from closing the door, he had to lead only three people to risk going to the gate.
