The monsoon was about to rise, and the Great Song fleet left the port of Seljuk and sailed out of the Persian Gulf.

As soon as the Persian Gulf came out, the wind at sea gradually strengthened, and the fleet, under the personal leadership of Yang Congyi, sailed directly to the south, and four or five days later, with the change of wind, the direction of the fleet began to shift to the east.

At the beginning of the summer monsoon, when the wind was not strong, it was the best time to seize the time to cross the Indian Ocean, so the fleet sailed day and night, sailing more than 400 miles in one day and one night. Since there are few islands in the Arabian Sea in the northern part of the Indian Ocean, let alone islands and reefs, there is no need to worry about the risk of hitting the reef and colliding with ships when sailing at full speed at night, so the entire fleet sails at full speed under the leadership of the first warship, day and night.

After seven days, the fleet turned eastward, full sails during the day, lowered the main sail and half the sail at night, and drifted on the currents and winds.

Two days later, the flotilla crossed a reef and continued eastward for a day, when it saw a continent and turned around and sailed south along the coast.

After a day, away from the mainland. After another day and a half of sailing to the southeast, another piece of land appeared in front of the fleet, but the navigator did not make any stops, and after rounding the land to the south, turned due east and sailed at full speed.

In the days that followed, the winds at sea grew stronger, and the fleet sailed day and night toward the east.

Some of the Seljuk nobles and merchants on the main ship of Shenzhou have been to Tianzhu, and they have also been to the eastern Champa country, but they have never seen such a sailing route of the Great Song Dynasty fleet, and the previous ships or fleets without exception all have to travel along the coast, from Seljuk to East Tianzhu, it takes half a year to sail, and if you want to go to Zhancheng, you must sail at sea for at least a year and a half.

However, the route of the Great Song fleet was very special, they only encountered land twice along the way, and they did not stop, and they were sailing at full speed almost the whole time, could it be that they had figured out the entire sea area and found a shortcut to safely cross the sea of ten thousand miles?

The merchants found Lord Huang to chat, asked about the route many times, and inquired about the charts, but unfortunately Lord Huang only asked about any specific things about the fleet, and he didn't know what he wanted to say.

But he told the merchants that the itinerary and route of the fleet had been determined before the Great Song fleet left the Great Song Dynasty, and in order for such a large fleet to go to sea, the Great Song Dynasty court spent a lot of effort and prepared for a whole year.

After the merchant and the envoy beat around the bush and listened to them repeatedly, Lord Huang told them that in fact, the itinerary of the entire fleet was determined by two people, one was Lord Tang, the person in charge of Hui Yi on the main ship, and the other was that they had seen Lord Yang in Baghdad, and if they wanted to know anything in the future, they could go to them.

Lord Huang didn't know how important sea charts were to a fleet and a nation, so he revealed many secrets that should not be revealed during the Seljuk snooping, including a pinwheel he had never seen.

After chatting for a few days, the Seljuks could no longer find any useful information from Lord Huang, so they began to turn to Tang Xun, wanting to find out more secret things from her.

As soon as Tang Xun heard them discuss the route back to Yihai Road in front of her, the businessman's intuition told her that these people had impure intentions.

The sea route is the business channel, master the unique sea route, you will master the way to make money, once shared with others, it is equivalent to the way to make money with others, if this business can only make so much money, more people involved, they will earn less money.

Tang Xun has been in contact with the medicinal herb business since he was a child, and although he is not proficient in it, he also knows a lot. For example, if there is a certain unique medicinal material in a certain place, and a medicinal herb dealer discovers this medicinal material first, he can eat enough by purchasing this medicinal material, and if another person comes to buy it, then he will have to collect half less, or even half in the future.

The reason why the Great Song Dynasty fleet has mastered a unique sea route, a hundred ships carrying millions of silk horses, a large volume, and the time spent on the road is also short. The Seljuks did not have this condition, and even if a horse of silk was sold for ten gold coins, they could only bring back 10,000 horses of silk from the Cham state in three years, and they could not make much money at all.

If they master the sea routes and build big ships, they will earn money on silk, porcelain, and tea in the Great Song Dynasty, and their spices, medicinal herbs, and jewelry will also be sold to the Great Song at a high price, and eventually they will earn all the money, and such a thing will naturally not happen.

Therefore, Tang Xun told them, in fact, this is all an adventure, the Great Song fleet has never gone abroad to the sea, how can it be possible to determine the itinerary and sea route in advance, it is just a lie to comfort everyone, the ocean is too wide, people are afraid, do not tell everyone that there is a definite itinerary and route, no one dares to go to sea, do not believe it to ask Lord Huang, it is estimated that he is afraid now and dare not go out of the cabin.

The Seljuks were skeptical, and obviously did not agree with this statement, but they could not refute it when Tang Xun said so, because when they stood on the deck and looked at the boundless, dark and dreary sea, and found not a small island, not even a single reef, they were very afraid, because it meant that there was no land within thousands of miles, and if the ship capsized and sank if they were unlucky, they would surely die. If it weren't for absolute trust, no ship would dare to enter this sea with no land islands and reefs for thousands of miles, and it seems that there is some truth in making up a lie to deceive everyone into going to sea.

After the problem of the sea route was not entangled, they inquired about the matter of pointing to the pinplate.

After hearing this, Tang Xun was speechless, why did Lord Huang tell outsiders everything, didn't he know the core of this fleet's sailing? But since the guests asked, they also had to give an explanation, so they told them that this pointing needle plate is actually an auxiliary tool to distinguish the direction of the stars in the sky, and the needle plate itself is not very useful, only when there are stars at night, it can only be used when there are stars at night, and it will not work on cloudy and rainy days, in fact, the complete name should be the star pointing disk.

After Sayal explained to the people, they were thoughtful, and they didn't know whether to believe it or not, and then they began to talk about the Great Song Dynasty and the return to Yi.

After the Seljuks left, Tang Xun found a few people on the main ship of Shenzhou who had the needle plate in their hands, and strictly ordered them not to disclose the information of the needle plate to others, and not to lend the needle plate to anyone, and Lord Huang could not borrow it.

Tang Xun on the main ship was fighting a secret battle, and Yang Congyi on the navigation ship was very anxious.

The winds and waves are getting stronger, and at this rate of development, it will not take three days for the monsoon in the northern Indian Ocean to strengthen significantly, and the fleet will be very dangerous. But even though the fleet is sailing at full speed, the mainland is still not visible in front of it, is there something wrong with the direction?

Yang Congyi found two needle plates, and paid attention to the sunrise and sunset, the ship has been sailing due east, and there is no problem with the direction. But according to the speed of travel, the fleet should have seen some islands early this morning, and now that the sun has set, there is no sign of the islands, and I really don't know what is wrong.

He quietly inspected a detailed map of the world in the cabin, the fleet had been sailing due east since it passed Sri Lanka, and it was logical that there should be no mistakes, and now there were no islands and reefs, and no mainland could be seen, and strong winds were coming soon, and if you did not sail with all your might, once you were chased by strong winds, the fleet would be in danger. However, directly east of the fleet are either reefs or islands, and if you continue to sail at full speed at night, it will be a big trouble to hit the islands and reefs.

After weighing it again, Yang Congyi ordered that at sunset, the main sail was lowered, and the auxiliary sail was lowered halfway, and the speed of the fleet suddenly decreased significantly, almost drifting downwind.

Yang Congyi didn't dare to sleep that night, and personally sat on the deck to inspect the sea route in the hazy night.

When the sun rose at dawn, he realized how correct his decision had been last night, because there was a small black line dozens of miles in front of the fleet, which was land.

As soon as the sergeant on the ship saw the black shadow, he shouted with joy that he had returned, and they had returned to Nanyang, how close to home Nanyang was! When they arrived in Nanyang, they would be able to go home in less than a month, and no one knew how much they wanted to go home.

Yang Congyi gave an order and asked the flag bearer to inform the ships behind him that the fleet was about to arrive in the South Seas, and that they should pay attention to the islands and reefs and drive carefully.

Half a day later, the fleet arrived at the northern end of the Strait of Malacca, and all the ships were ordered to hoist the Great Song flag, lower their sails, and cross the strait in a southeasterly direction at low speed.

Three days later, while the navigation warships were sailing, the navy of the Srivijaya Kingdom at the entrance to the northern end of the strait appeared, and dozens of their ships quickly stopped in front of the navigation warships and blocked the way of the fleet.

The Great Song warship was tall and sturdy, and the Xuanwei army had destroyed the Srivijaya people who blocked the road again last year, and now they came back from Seljuk, where did they still take them in their eyes, and directly crashed into the small boat blocking the road and continued to sail.

"My lord, it's not good, the sea road ahead is blocked by a lot of ships, and I can't pass through." I didn't sleep all night, and after the fleet entered the strait, Yang Congyi, who was resting in the cabin, was suddenly woken up.

As soon as he heard that the sea route was blocked, Yang Congyi immediately got up and went out of the cabin to inspect.

When I came to the deck, I saw dozens or hundreds of ships parked on the sea in front of me, with different styles and sizes, and from the flags hung on the ships, they did not look like the army of the Sriwijaya royal family.

Could it be that which family is doing the trouble? Yang Congyi was shocked, if this is the case, there will be a big trouble.

The fleet has been sailing continuously for more than half a month, the Xuanwei army is very tired, the spirit and morale have been greatly reduced, and the fleet is also in urgent need of replenishing fresh water and supplies.

These roadblockers, who had previously guarded the southern end of the strait, when the fleet went south from the Great Song Dynasty, sailed for nearly a month, was very tired, and was almost blackmailed by them, and now the fleet has returned from the Western Ocean, and after a long voyage, it is in this tired time to blackmail, these villains who take advantage of people's danger!

Yang Congyi looked at the many small boats facing the warships on the sea in front of him, and couldn't help but want to scold, but in the end he held back, anger was useless, he should think about how to solve the problem.
