And more importantly, after dumping at such a low price, even if the freight is added, Datang Western Trading Company still makes money in the cloth business, and the profit is not small.

This is because the production cost of cotton cloth in the Tang Empire is very low, and after the use of a large number of machinery and equipment, especially steam engine power, is applied to the factory, the manufacturing cost of cotton, a typical light industrial product, has become extremely cheap.

The cost of the cloth purchased by the Datang Western Trading Company from China is low, so it can naturally be bought cheaply in India.

What's even more interesting is that Datang Western Trading Company does not always dump at low prices in a certain area.

The early low-price dumping is to compete for the market, squeeze the local cloth industry, and after the local handmade cloth industry is finished, Datang Western Trading Company will slowly increase the price, and finally rise to a reasonable level.

After all, Datang Western Trading Company is here to make money, not to do charity, and it has always been dumping so cheaply, so that the locals can afford to wear clothes even if they are poor, which is not the original intention of Datang Western Trading Company.

Profit maximization is always the pursuit of Datang Western Trading Company!

Relying on industrialization to produce in large quantities in order to reduce costs is a clear feature of the current industrial development of the Tang Empire.

This is why cotton cloth does not seem to have any technical content on the surface, but the cotton cloth of Datang is the reason why the home-made cotton cloth of other countries can be killed.

And this advantage is also something that other countries cannot imitate!

So over the years, the Portuguese have not thought about copying some of Datang's products, but they can't do anything about it.

However, they still copied a lot of things that did not require industrial technology and could be imitated by manual production by craftsmen, and Tang Chuan is one of the typical examples.

The Portuguese began to imitate and build Tang ships very early, at first it was only built on a small scale in Malacca, mainly for merchant ships, but it was soon applied to the field of warships, and later this shipbuilding technology was also brought by the Portuguese to other places and even their own country.

After all, the Portuguese were not stupid, they found the Tang ship, which was much better than the previous carat ship, and compared with the Galen ship, it also had its own merits.

The difference between the Tang ship and the Galen ship is generally that the Tang ship has fast speed and good seaworthiness, but under the same tonnage, the cargo capacity is less than that of the Galen ship.

In addition, the Tang ship also has an advantage that the Galen ship does not have, that is, the hull of the Tang ship is more suitable for arranging guns, and at the same time the sinking resistance is better, and this performance is extremely important for warships, even for contemporary ocean-going merchant ships, because even if it is a merchant ship, it is all armed merchant ships these years, and it will carry a large number of naval guns.

After all, the Tang ship was designed as a warship at the beginning, and later it was used as a merchant ship after improvement.

Because compared with other sailing ships of the same era, the Tang ship was more suitable for arranging artillery and more suitable for combat.

After the Tang ships were copied by the Portuguese in Malacca, they gradually entered Europe, and now the Portuguese have begun to build some Tang ships in their own country.

Therefore, in Malacca today, Admiral Chen Pengming, commander of the Indian Ocean Fleet, was able to see a large number of Tang ships in the port of Malacca, many of which were warships.

However, although the Portuguese also used many Tang ships as warships, Admiral Chen Pengming did not have any unnecessary worries.

If it was in the era of sails, he might still be worried, after all, warships of the Tang ship type are more suitable for combat than Galen ships and carat ships, but now, it is already the age of steam.

The pure style of the battleship is already completely outdated!

In the internal exercises of the Datang Navy, a steam cruiser was created to use steam power to constantly maneuver, seize the wind direction, and finally defeat the small fleet composed of two sail battleships!!

Although the original exercise was not a live-fire exercise, but a simulated exercise, and the results of the exercise were extremely accidental, it is undeniable that the battleship loaded with a steam engine completely destroyed a pure sail battleship in terms of maneuverability.

What's more, the Datang Navy also has an advantage in ammunition, that is, grenades!

Datang has used grenades for many years, not to mention the kind of grenades with external fuses in the early years, and grenades with built-in fuses, after so many years of development, they have already developed maturely, and they have been widely equipped with the whole army, basically more than five catties of artillery, and now they are all grenades that can use built-in fuses.

And the lethality of the grenade against the sail battleship, that is huge!

The explosive power of the grenade can effectively kill and injure not only the personnel on the enemy ship, but also effectively destroy the superstructure of the enemy ship, especially the mast and sail!

Sometimes, if you are lucky, it is often a large-caliber grenade that hits an enemy ship, which can basically destroy the enemy's sails and turn the enemy ship into a dead fish that can only float on the surface of the sea!

Moreover, some large-caliber grenades, the huge kinetic energy brought by huge shells, can also penetrate the enemy's wooden hull, and then penetrate deep into the enemy's ship and explode, such an explosion is very deadly.

This is also the reason why the Datang Navy is equipped with wrought iron armor belts on new warships.

It is because the grenade is too lethal for a wooden battleship, and adding a layer of wrought iron to the hull can effectively resist the attack of the grenade.

In addition, the Steel Armor Belt is not only excellent for grenades, but also for solid bullets!

With the development of technology, the Datang Navy believes that the steel armor belt is very necessary!

After all, the grenade is not a patent of Datang, after all, this thing can't be kept secret too well, the grenade with the built-in fuse is okay, this thing is more difficult to produce by hand, but the grenade with the external fuse, there is basically no technical difficulty.

The Portuguese were also equipped with this kind of externally fused grenade early on, and used it exclusively on their 64-pounder and other large-caliber mortars.

Although this kind of mortar does not look good, it is actually quite a threat to the wooden warships of the Tang Navy.

During the rise of the Tang Empire, although a strict technical blockade was carried out, until now, it has strictly prohibited the export of any machinery and equipment, high-precision industrial products, especially all kinds of machine tools and steam engines.

Not only is it not allowed to export, but even the overseas territories under the control of Datang are not allowed to be purchased and used.

One of the most famous is the ban on factories and the ban on education.

So far, the Tang Empire still prohibits the establishment of educational institutions above the middle school level in overseas territories, and at the same time prohibits the establishment of any type of factories without permission.

In fact, the Import and Export Board has never approved any such application!

However, Rao is the Tang Empire has established such a strict technology blockade system, but it is still difficult to completely eliminate technology leakage.

Whether it is the Portuguese, the Tatars, or even the Spaniards, they are all able to obtain some technology of the Tang Empire through some illegal channels, and even legal channels.

For example, the Tatars, but they sent spies, openly in the hinterland of the Tang Dynasty to buy almost a full set of textbooks, from primary school to the preparatory stage, and even some of the university textbooks circulated through private channels, and through illegal channels, such as kidnapping, directly kidnapping some technical craftsmen, and then secretly transported back to the Tatar control area, in the early years, the Gansu Ammunition Factory under the Northern Arms Company, there were more than ten technicians missing at one time, and the local patrol police station could not solve the case at all. Later, after Han Tong accepted the case, he soon found out the truth.

These more than a dozen unlucky technicians were kidnapped by the Tatars, and they were all taken out of Jiayu Pass and into the Tatars' controlled area.

After all, the border between the northwest and the north is so long, and it is okay for Datang to blockade large caravans, but it is absolutely impossible to block the behavior of a few people crossing the border line.

Interestingly, the main purpose of the Tatars' various stealing techniques was to make guns, and the results were also there, at least now the Tatars can already make guns and cannons, although they still make arquebuses and early artillery, and they can only be produced by hand.

But at least it solves the problem.

With their own guns and artillery, combined with their own large cavalry superiority, the Tatars were almost invincible in Central Asia, connecting and destroying the Yarkand Khanate and the Kazakh Khanate, and now they are fighting with the Timurid dynasty, and according to the grapevine, they have already made contact with the Safavid dynasty further west.

Of course, this kind of contact is not a good contact!

The Tatars' expeditions to the west were never to be guests of other people's homes, they were to rob other people's homes!

Over the years, the Tatars have been at war with neighboring countries almost every year, and the expansion rate is extremely fast, although there is a reason for their huge cavalry advantage, but this is also related to the fact that they have obtained gun-making technology from the Tang Empire.

The cavalry is naturally a good hand when fighting in the field, and even the Tang Army is afraid of the Tatars' army of more than 100,000 cavalry!

But they can't conquer the cities of Central Asia with cavalry alone!

When they attacked the city, they also used guns!
