The war in the Indian Ocean ended quickly.

The Zhuluo Navy has its own B number in their hearts, they can be the king and hegemon in the Tianzhu Sea area, and they are the great empire of the Tianfang world, and they are not **. However, when facing this Lu Qi Sailor, he had no qualifications to be proud at all.

The superiority of the Chinese in artillery is not broken for a day, and they are not even qualified to parry.

The bloody third brother is also a drop, but just like the Manchumizu Division who went to block the British fleet during the First Opium War, he failed to cause the slightest damage to the opponent, but he ended up with the annihilation of the whole army in a short period of time.

Kulu Tonga Choro II issued a direct 'severance order'. A naval force that could dominate Tianzhu just 'disappeared' and was hidden in the long coastline of the Chola Kingdom.

But even then it's still not safe. Because the coastline of South Tianzhu is too smooth, far less rugged than the north of Ceylon, let alone compared with the South Sea. It's just that Ceylon is the fat meat targeted by the Chinese, and Kulu Tongga Choro II has no confidence to resist this wave of Chinese attacks, so naturally it is impossible to hide the warship in Ceylon.

He had just succeeded to the throne when he encountered this kind of thing, and his authority was directly shaken. Even if we deal with this wave of crisis, it will have far-reaching consequences. Gritting his teeth with hatred for China.

But the development of the battle situation will not be transferred by his will.

In the fourth lunar month, the Qi army had already established a strong foothold in Ceylon, and then eyed Chola proper.

Kulu Tongga Chola II also gathered a heavy army, but the coastline of Chola was so long that even if he had gathered his army with all his might, he would be overstretched.

The Qi army did not keep Kulu Tongga Chola II waiting, and on 25 April, a full fleet of five ships marched north under the northeast wind, and simultaneously launched an attack on five port cities on the eastern coastline of Chola.

One of them is Gidenboram, where the tributary of the Cauverry River Delta flows into the sea. The five invasion points chosen by the Qi army this time all have similar geographical locations.

- The estuary of a river.

Because in this way, the small and medium-sized warships in the fleet can be called to go straight down the river into the hinterland of Nantianzhu.

Just like the Gaoveri River, which is one of the many great rivers in South Tianzhu, and is also the essence of the Chola country, although the middle and upper reaches can not be navigated smoothly because of the huge drop, but the banks of the river for hundreds of miles downstream are one of the most developed areas of agriculture in the Chola country. At the same time, the capital of the Chola Kingdom was also located here.

Naturally, the Chola Kingdom had an army in the area, and there were two small dhows roaming around the estuary area. From afar, I found the Chinese fleet approaching, and the red flag hanging on the mast was full of blue sky and white sun.

The latter was originally the naval flag of the Republic of China. It's a lot more stylish than the dragon.

The two small boats immediately spotted the Qi army ships flying the red flag of the blue sky and the white sun, and in the face of such a strong enemy, the two small dnahow boats turned around decisively and began to run away.

At the mouth of the river, however, they were overtaken by two small schooners.

Ten years. The new style of sailing ships has been developed to a great extent in the Lu Qi Naval Division.

In particular, the appearance of the upper edge of the diagonal truss sail.

The appearance of this thing has nothing to do with Emperor Lu at all, it is purely the master masters of the Ship Division who came up with it themselves.

The cumbersome operation and labor required by the new sailboat have always been its biggest 'drawback', compared with the traditional hard sailboat. In the process of manufacturing and sea trials of experimental ships, the ship division found that although the soft sailing ship has the advantages of fast speed, relatively solid hull structure, large deck space, and higher utilization efficiency, its disadvantages are also obvious. When the climate is changing rapidly, the sails are frequently lifted and landed when sailing, and the labor intensity is particularly high, so the number of sail operators must be huge.

This is clearly contrary to the requirements of military ships.

Especially in China, a country that has been accustomed to maneuverable hard-sailed ships for thousands of years, this defect is simply unbearable.

But the defects of the latter are obvious, the huge force of the hard sail on the mast determines that the height of the mast should not be too high - in the era when modern metal materials such as aluminum alloy did not appear, there is really not much room for improvement in hard sail ships.

Therefore, in the past ten years, China's shipbuilding industry, especially the warships in the army, has always been the main direction of attack on new sailing ships represented by soft sailing ships. Although it has such a big "flaw".

It is impossible for the ship department to look at the "defects" and be indifferent, they have carried out experiments and improvements again and again, in the process they found that one of the most serious points of personnel labor consumption is the steering problem of the spinnaker, which is too cumbersome and inconvenient to operate. Therefore, in order to facilitate the rotation of the sail boom, the shipping department directly cut off the first half of the sail boom (that is, the lower edge boom) that was in the way.

However, in this way, the spinnaker lost half of its boom, and although it was easier to steer, its area was also reduced by half, and its ability to harness the wind was greatly reduced, and the speed of the ship was reduced. This result is unacceptable to the shipbuilding division.

So, they began to turn their brains to figure out how to make up for the loss. They took a step under the mast and made a wind pole that could be rotated around the mast. The wind lever is perpendicular to the mast and is connected to the bottom of the mast with a metal collar. In this way, the sailor can pull the wind lever directly in the horizontal direction with his hands or rope.

The upper edge of the girder, which has been retained, is also connected to the mast by a metal collar. However, unlike the wind pole, the wind pole is perpendicular to the mast, and there is an angle between the upper edge of the girder and the mast, and its angle is still the same as when the lower edge of the cross was retained.

As for the sails, they are drawn between the wind bar at the bottom and the upper edge of the boom above. In this way, the sail shape becomes a rectangle with a right triangle on top. The area of a square of the same height and width is twice that of a triangle, so the area of the new upper edge jigster is no smaller than that of the spinnaker when the lower edge jigster is retained. What's more, a right-angled triangular jib can also be added to the top of the upper edge of the jirs, which further increases the sail area and strengthens the wind capacity.

Moreover, the manoeuvring of this new type of sail is exceptionally simple. When the wind changes, the sailor only needs to rely on the winch rope to control the direction of the wind pole on the lower edge of the upper edge of the diagonal truss sail, so that it can rotate in the opposite direction with the mast as the axis. Even, one or two sailors can easily handle the reversal of an upper edge jigs, and in a very short time.

At this point, the performance of the soft sailing ship has been greatly improved, and after Emperor Lu looked at the experimental boat, he also felt that the sail seemed to be more pleasing to the eye, and it seemed to be closer to the soft sailing ship in his memory.

In the next few years, there were a lot of soft sailing boats in the Lu Qi Naval Division. The volume of the latter has also risen rapidly from less than 1,000 koku to 5,000 koku. Just counting the displacement, it is already very close to the thousand-ton sail warships of later generations.

The two small sail warships that rushed out at the moment were all small shrimps with a load of less than 1,000 stones, but their firepower was not weak and their speed was faster.

After catching up with the two small dhows, they were bombarded with direct artillery. The latter, too, seemed to find it impossible to escape, and began a desperate return fire with the few ballistas on board, and some courageous crossbowmen also stood on the sides of the ships and fired at the two small sail ships. It's just that because the distance was too far, most of their shots fell into the sea, which made the sailors on the two Qi sailing ships laugh loudly.
