A small number of hardliners in Nanchang and other places were also confused by Liu Qi's complete decentralization, and hesitated to sit back and watch the surrounding counties and clansmen hand over their military power, and they couldn't twist their arms and thighs.

However, Liu Qi did not get carried away, he clearly knew that he benefited from the suppression of Yuzhang counties under the banner of Liu Zhang and Liu Biao, and then acted quickly and took correct measures to gain a firm foothold in such a short period of time, but the policy adopted now is not a long-term plan after all, and the rights will be taken back sooner or later, which will arouse a strong reaction from the big clans around the country.

Liu Qi estimated that in a year at most, various external and internal problems would occur, and if he wanted to withstand the pressure and develop and grow, the only way to strengthen the strength of the lineage was to strengthen the strength of the lineage as soon as possible, so that the people who were vacillating internally would not dare to act, and the neighboring princes would not dare to attack easily.

I don't have much time left for myself!

The content of today's training is to assume that an enemy ship is coming, and set up an ambush for the enemy ship to enter the encirclement and then flank the attack.

Liu Qi is now located in the later generations of China's largest freshwater lake Poyang Lake, in the Han Dynasty called Peng Lize, the gateway of Yuzhang Chaisang is extremely strong, easy to defend and difficult to attack, the current main enemy Liu Xiang is likely to take the siege of Chaisang without fighting directly into Peng Lize to take the heart of Yuzhang, Nanchang!

The Yangtze River often floods, the river water pours into Peng Lize and floods the surrounding areas, so the counties along the lake are sparsely populated, and they are not suitable for building cities, the enemy can easily avoid the defenders of the counties and land directly to Nanchang, Nanchang is the seat of Yuzhang County, once the political center falls into the hands of the enemy, the other counties will become a plate of scattered sand overnight, even if it is recaptured, it will cause irreparable losses.

Liu Qi's troops are limited, and the soldiers recruited from each county are only about 13,000 people, and the scattered defense is not enough to see, Chaisang is divided into half, Wengang garrisons are 3,000, and most of the rest are transferred to Poyang, Nanchang only has 2,000 defenders, although it is actively recruiting troops and horses, but the population of Yuzhang County is too small and too scattered, and the speed is much slower than Liu Qi imagined.

Therefore, the current focus is to keep all the invading enemies out of Peng Lize, if the naval army is strong enough, with the protection of Chai Sang and Peng Lize, there is basically no need to worry about the rear.

The soldiers trained very hard, they were still sweating profusely in the cold lake, and many soldiers took off their clothes and were shirtless, but Liu Qi was not satisfied with the training results.

It's not that Gan Ning's training ability is not good, Gan Ning is indeed a good general, and he is deeply loved for sharing weal and woe with his soldiers, and he can't find any fault with his technical and tactical level.

In fact, before this, Liu Qi had a very vague impression of the combat mode of the navy in this era, and it was not until this time that the warring parties approached the boat, shot bows and arrows or threw short-handled spears and spears at each other, and then boarded the ship to fight hand-to-hand, this is the main combat mode of the navy now, this simple and cruel combat method is full of uncertainties, and the fighting skills and will of the soldiers are the protagonists, so the focus of the training is to identify and implement military orders, various formations and fighting skills of the soldiers.

But no matter how elite the soldiers are, hand-to-hand combat will always bring a lot of losses, and Liu Qi can't do anything about killing a thousand enemies and losing eight hundred, and he can't afford to lose, so Liu Qi habitually put his thinking on improving the performance of equipment and then improving tactics from the beginning, hoping to break through the tradition and win by technical superiority, and try to avoid the loss of his own soldiers.

Liu Qi's idea is good, but it is too transcendent, and when he implements it, he finds that imagination and reality are simply worlds apart.

For example, the most basic warships, whether they are small sampans or newly emerging building ships, the ships of the Han Dynasty are flat-bottomed, although the flat-bottomed boats have a small draft, which is convenient for passing through the shallows and mooring close to the sandbar, but compared with the V-shaped or U-shaped pointed bottom boats, the speed and the ability to resist grounding and wind and waves are far inferior.

If we add advanced technologies such as laying keels and watertight cabins, the sharp-bottomed ships can combine the advantages of speed, sturdiness, and stability, and greatly enhance the combat effectiveness of the navy.

However, Liu Qi himself knows nothing about shipbuilding, even if he proposes an advanced transformation plan according to the experience of later generations, it also needs to be understood by shipbuilders and experimented step by step to slowly realize, even if the craftsmen quickly master the new technology, but also the productivity can keep up, the whole Yuzhang only Chaisang, Yun (sound with Yun) Yang and Nanchang three counties have shipyards and craftsmen who can build warships, and the production speed is far behind Liu Qi's expansion speed.

Moreover, the improved ship can only have a certain degree of superiority in mobility and defense, and it is impossible to win by directly ramming and sinking the enemy ship, and it is necessary to think about other new technologies that can be directly turned into battle results.

If you want to avoid hand-to-hand combat, the only way to improve the army's long-range attack power is to improve the army's strong bow, the strong bow of the Han Dynasty can be described as extremely sharp, but unfortunately few people can use the hard bow with more than two stones, and the range and accuracy of ordinary bows and arrows cannot achieve the purpose of preventing enemy ships from approaching.

There is another point that Liu Qi did not know before, that is, the loss rate of the bow in a humid environment is greatly accelerated, because the bow arm and bowstring are bonded with glue made of animal tendons such as fish glue, and the degree of adhesion is greatly affected by temperature and humidity, especially in the rainy season, when it is frequently wet and then exposed to the sun, the bow arm and bowstring will soon loosen.

A good bow that can be used for five years in the north can be maintained here for two years at most, and the hardness and accuracy of this bow will be greatly reduced after two years, not to mention the bow in the hands of ordinary soldiers.

In addition, due to the different materials of wood in the north and south, although the life of the bow in the south of the Yangtze River is far lower than that in the north, the production cost is only high.

In addition to bows and crossbows, crossbows are one of the most powerful weapons in cold weapons, crossbows of the same strength are much more accurate and penetrating than bows, but the range is not as good as and due to the slow speed of the arrow, the rate of fire is the biggest weakness.

In this regard, Liu Qi can finally play a role, there are two famous crossbows in history to successfully solve the problem of rate of fire, Zhuge crossbow and the Ming Dynasty's repeating crossbow, the Three Kingdoms Note cites the book "Wei's Spring and Autumn" records, Zhuge crossbow is Zhuge Liang in the Qin Dynasty on the basis of the three-shot crossbow improved can fire ten eight-inch long iron arrows at a time multi-shot crossbow, called "Yuan Rong".

It's a pity that this invention was lost, until the 21st century, its structural design is also unknown, let the world know is the crossbow used by the army of the Ming Dynasty, the structure of the crossbow in the Ming Dynasty is not complicated, the arrow box above the crossbow machine can hold twenty or more iron arrows, the arrow box and the crossbow string are connected, the shooter pulls the arrow box after firing, and the lever principle is used to complete the winding again, and the iron arrow in the arrow box of the curved structure falls by gravity, and the shooter can shoot again.

This kind of repeater is easy to carry and use, one hand can be aimed at firing, the rate of fire is extremely fast, the penetration of the iron arrow is much larger than the arrow of other materials, although there is no tail feather range is insufficient, but for the naval combat, fifty steps away even a hard bow is difficult to be accurate, the performance of the repeater can fully meet the combat needs of the current naval army.

Moreover, the structure of the repeater is simple, easy to disassemble and assemble, all parts are universal, it is easy to manufacture on a large scale, and the maintenance and repair are economical and convenient, which is what Liu Qi, whose pockets are getting tighter, urgently need.

In addition to the repeater, Liu Qi also has a secret weapon, a grenade!

One of the most important aspects of Liu Qi's plan to improve communication methods is fireworks, and to make fireworks, gunpowder must first be made, and the effect of gunpowder is too great, and it is too wasteful to use it only to make fireworks.

Due to the limitations of smelting technology, in this era, Liu Qi did not expect to be able to make guns, even if he barely made them, it was impossible to meet his own requirements, and the effect was not as good as a bow and crossbow, except for grenades, Liu Qi could not think of any other way to make full use of gunpowder for the time being.

Even if the largest three-story ship can not withstand the explosive power of a military defensive grenade in later generations, of course, the ******* used in the grenades in later generations is far more powerful than the gunpowder that can be made now, but Liu Qi's requirements are not high, he can catch up with one-third, and he can use multiple charges to increase his power, as long as the two sides are within thirty steps and throw one or two grenades into the enemy ship, they can completely turn their heads and look for the next target, because the ships of this era have no keel and cannot withstand the impact of grenade explosionsEven if the ship sinks, there will be few people left on the ship who can fight after the explosion.

If you succeed in making a grenade, at least it is not a problem to walk sideways in the Yangtze River Basin, Danyang and Wujun are not a piece of cake, not only the naval army, infantry and cavalry can also run rampant in the world, relying on the Yangtze River to attack and retreat and defend, if it is not for the time is tight, the world can also compete, what are the rabble of Zhang Jiao, Liu Qi can't help but be extremely excited when he thinks of this!

However, this great invention can not be realized for a while, because the necessary raw materials for the manufacture of gunpowder are not readily available, one is charcoal, charcoal needs to be fired under specific conditions, and it is very susceptible to moisture, so no one will store a large number of them in the south of the Yangtze River in the humid air, and it takes a lot of effort to collect a large number of them, and the second is sulfur, sulfur is a medicinal material, which can be refined and is not easy to be expensive, and there are many alternative drugs, so there are few doctors who use it in a place a little far from the place of origin, and the third is potassium nitrate, which needs to be refined from the nitrate soil to obtain. Nitrate is still relatively easy to collect, and there are some of the corners of toilets, pigsties, and corners, but purification is laborious and takes a lot of time.

After running all over the blacksmith shops, hospitals and bazaars in Nanchang and Chaisang, he finally found some charcoal, but found a lot of sulfur, Liu Qi forgot that another major function of sulfur in ancient times was alchemy, and the main raw material for alchemy.

Liu Qi spent a lot of money to attract merchants to sell charcoal and sulfur from all over the north, and at the same time ordered the collection of nitrate from all over the country for purification, and he first tested the small amount of raw materials he had collected.

In a small tent, Liu Qi stared closely at the powder mixed with a handful of charcoal, sulfur, and amine nitrate, which took a whole day to purify, took a deep breath, and threw the torch over.
