The impact of the Tang Dynasty's opening of science and technology is far greater than Li Xuan's own estimate, because Li Xuan, who is in it, does not feel it obviously, but in the outside world, especially in Guangzhou and eastern Guangdong, which are still controlled by the Ming army, the news about the Tang Dynasty is widely circulated among scholars, and the impact is quite great.

Even if these places are still under the control of the Ming Dynasty, many people know that the reason why the Ming Dynasty is still able to control these places is because the Tang Dynasty has suspended large-scale military operations in Guangdong because of the rainy season.

After May and June, when the rainy season has passed and the hot summer comes, especially when the summer harvest comes, then the puppet Tang thief army will relaunch a large-scale attack.

Ancient and modern wars, affected by the seasonal climate is very great, not to say that you want to fight if you want to fight, at least after the capture of Zhaoqing, in the face of the daily rain, there are only a few days of sun in a month, the world's strongest army Tang Wang Division is also powerless to do anything about this, can only suspend the large-scale offensive in Guangdong, especially against Guangzhou.

Instead, he rested on the spot and sent small forces to capture some small cities that were not garrisoned by too many Ming troops, such as Foshan.

After the capture of Zhaoqing, the First Army led by Hao Bonian continued to lead the main force of the First Army to the south after welcoming the arrival of the Holy Driver in Zhaoqing, part of which approached Guangzhou, and the other part went to seize Foshan and other places, and also sent troops to attack the central and western regions of Guangdong, where there was no large-scale Ming army, at least a small number of local garrison troops.

Even if the rainy season is coming, causing the Tang Dynasty Division's march, supply transportation and even combat difficulties, it is still possible to take these places.

The strategic focus of the Tang Dynasty's division in Guangdong was adjusted to a local small-scale offensive to seize other places in western Guangdong, and the main force rested and recuperated, which also gave the Ming army in Guangzhou a large amount of strategic buffer time.

This made Wang Yue, the governor of Liangguang, in the battle report sent to Zhang Yue, the governor of the four provinces, and it can be said that after a strong battle, he thwarted the plot of the puppet Tang thief army to attack Guangzhou.

After the Tang Dynasty's offensive against Guangzhou and the eastern and northeastern parts of Guangdong was slowed down, these places were still under the rule of the Ming Dynasty, but this rule was already crumbling.

The gentry and landlords were panicked, some people wanted to escape, some of them fled to Guangzhou, after all, in the eyes of outsiders, Guangzhou is already the last remaining city in Guangdong that can be used to resist the attack of the puppet Tang Dynasty thief army, if you flee to Guangzhou, you can at least save your life, and you can escape directly from Guangzhou by boat when you don't get it, out of the Pearl River estuary is the sea, no matter how powerful the puppet Tang thief army is, it is impossible to go to the sea to fight them.

When the Tang Dynasty division went south to Guangxi for a long time, many people could also be able to use the puppet Tang thief army's army to be very strong, and the official army and its field battles were often more defeats and fewer victories, but the naval division of the puppet Tang thief army was not good, the number of warships was not much, and they were all small boats, not to mention going to sea to pursue, in fact, even the Xijiang River to the east of Zhaoqing could not bargain.

Therefore, as long as the land and mountains cannot be defended, you can still hide from the sea and escape.

A group of high-level officials of the Tang Dynasty Division also knew this, even Li Xuan, the emperor, knew that his own naval strength was too weak, and it was okay to transport and transport materials without the threat of enemy naval divisions in the rear, but it would be too difficult for them to run to the mouth of the Pearl River to fight hard with the Ming naval division.

Li Xuan knew that there were only two ways to change the disadvantage of the navy, one was to learn from the Ming army's sailors, build countless small boats to play traditional fire attacks and hand-to-hand combat, and the other was to take the road of strong ships and guns.

And no matter which of these two items is, it is extremely difficult for the current Tang Dynasty Prince.

Compared with the number of Tang Wang Division, it is definitely not comparable to the Ming Army's naval division, not to mention the Ming Army's national naval division, even if it is a naval division in Guangdong, it can suppress the Tang Navy.

The only feasible way is to go to the road of strong ships and guns, build big ships, build big guns!

But there are two new problems that have emerged, that is, the shipbuilding capacity of the Tang Dynasty is not good, even if it is to purchase ships from the people, but the number is not much, and it is too late in time. If the problems of the hull itself can be solved, then the problem of naval guns is almost unsolvable.

According to the scale of the Datang Navy, a capital warship used on inland rivers needs at least two five-pound cannons, and then four two-pound cannons, plus one or two large-caliber shotguns.

These artillery pieces are roughly equivalent to the artillery required by an artillery team of the army.

The artillery production of the Tang Dynasty was still very low, and even the needs of the army were far from being satisfied, and there was not much output to supply the navy.

At present, there are a total of five artillery battalions in the Tang Dynasty's division, and according to the full establishment, they should be equipped with 90 five-kilogram field guns and 18 seven-kilogram field guns.

But in fact, these five artillery battalions are all seriously lacking, even the most powerful firepower, the first artillery battalion used by the First Army, there are only 12 5-pound field guns, 3 7-pound field guns, a total of only 15 field guns, and there are also six 2 or 300-pound bowl guns captured from the Ming army.

The Fourth Artillery Battalion under the jurisdiction of the Third Army, which was fighting in western Guangxi, did not have a single field artillery, only a few bowl-mouth guns of 3,500 catties captured from the Ming Army.

The army units of the Tang Dynasty's division, including the Guards, only have about 20 five-pound field guns and six seven-pound field guns.

As the core of the empire, the army units are only a few dozen artillery pieces, but now the navy is already equipped with six five-pound cannons, and there are more than a dozen two-pound cannons specially built for the navy, and this artillery power can be said to be not weak.

It is already very difficult to equip more artillery.

There weren't enough guns, and a few more hulls weren't really useful.

For the navy, a few guns on a battleship are already very few, and a real battleship, especially a battleship in a fleet duel, which one is not dozens of guns, and it must be more than seven catties or even ten catties or even twenty or thirty catties of heavy artillery!

The weak navy also led to the fact that when attacking Guangzhou in the coastal zone, the army should not be disappointed to be able to get strong support from the navy, and it was not easy for the Tang Navy to maintain the transportation and escort of the fleet on the Xijiang River.

The strength of the naval division of the puppet Tang thief army was weak, which was also an important reason why Wang Yue and a large number of senior civil and military officials of the Ming army in the Liangguang region dared to defend Guangzhou.

Because they all know that even if they can't hold Guangzhou, the big deal is to retreat from the Pearl River, and their lives are worry-free.

Naturally, these high-ranking officials were not the only ones who knew this, but also some gentry and landlords with insight and foresight were also heading towards Guangzhou, a city that could be defended and retreated.

However, some people simply fled from Guangdong, they went to Jiangxi, Huguang, Fujian and other places, and the gentry and landlords who fled in these directions believed that even if Guangzhou could resist the thief army for a few months, but when the summer came, when the main force of the thief army gathered under the city of Guangzhou, Guangzhou could not hold it, and if it had to run again, it was better to run to other provinces now.

Of course, the number of people who can escape is actually only a very small part of the local population, and most of the peasants are still in the middle class of society, and they have no way to escape.

Because if you run away, you will be throwing everything at home, ordinary people will become displaced people in minutes, and for the ordinary middle class, running away is also equivalent to throwing away your family business, and when you go outside to escape the war, it is inevitable that your family will be ruined.

Moreover, although the Ming Dynasty advocated how brutal the pseudo-Tang military was, people's eyes were bright, especially when the news of the Tang Dynasty's opening of science and technology came out, it made this rumor even more self-defeating.

The reason is simple!

When a rebel gang opens a sect, it means that the gang has moved away from the model of thieves and bandits, but has entered the stage of a regular dynasty.

And for any dynasty, population and resources are the basis of rule.

Therefore, those ordinary middle class, such as small and medium-sized landlords and small and medium-sized businessmen, they don't think that the puppet Tang thief army will still burn, kill and loot with the past, as long as they don't resist stupidly, their lives can be saved.

As for ordinary peasants, they don't care about such national events as the change of dynasty, as long as they can continue to farm and maintain a stable life, they actually don't care about the changes in the outside world.

What they really care about is those big businessmen, big landlords, especially the official families who are close to the Ming Dynasty, such as the families of the captains of the Ming Dynasty, who are most concerned about the puppet Tang thief army, and at the same time, they are also the most afraid of the puppet Tang thief army.

These changes in the outside world, Li Xuan doesn't care about it now, and he can't care about it, but now his eyes are staring at Guizhou and Huguang.

Although the large-scale military operations of the Tang Dynasty Division in Guangdong stopped, the military operations in Huguang and Guizhou did not stop, but became more intense.

Coastal Guangdong has entered the rainy season, even in Guangxi, but although the weather in Guizhou and Huguang is a little gloomy, it is still able to continue fighting.

Because whether it is the Ming army or the Tang army, it is a continuous military operation.

Fang Xitong on the Guizhou side had already led the main force of the 3rd Infantry Regiment of the 2nd Army and the 4th Garrison Regiment of the 2nd Garrison Brigade in central Guizhou, with a total of about 5,000 people to return to Liping Province, and in mid-March, he repelled many Ming army divisions that had infiltrated Liping Province and recovered the Tonggu Acropolis.

After sweeping away the Ming army's partial division in Liping Mansion and ensuring the strategic security of Liping Mansion, Fang Xitong continued to lead his troops eastward, trying to relieve the siege of Xingquanfu City, repel the Ming army, and rescue the remnants of thousands of defenders in the city.

However, as soon as he entered Xingquan Mansion, Fang Xitong suffered a big defeat, with more than 4,000 troops killed and wounded, seven or eight hundred, and finally he could only flee west in embarrassment, fleeing all the way back to Liping Mansion.
