After a month and three days in the capital, Liang and Ao Lei finally completed all their work and returned to Haijin, and then hoisted their sails and headed north with a whole fleet of supplies transporting supplies.

In autumn, the sky is cloudless, and the blue sky is like a large blue satin in the sunlight, blending with the equally blue sea.

In the vast sea, the sails of Liang En's ships hung high like white clouds falling from the sky, and the traces of the boats on the water shattered the calm sea, making it all like a dream.

The flagship, named Speed, glides gracefully across the water like a swan, and the triangular soft sails on the three masts fill the wind, causing the ship to stir up two snow-white waves.

Ao Lei stood at the top of the mast, holding a rare binoculars and observing the surroundings, this place is the Tsushima Strait, which is still a war zone, so it is necessary to be vigilant against enemy attacks.

That's right, Goryeo still hasn't surrendered, it's not that the other side has high morale or hard backbone, but purely because of party strife, no one can come out to sign this contract and take the blame by the way.

To be honest, party strife can be regarded as a Goryeo tradition, and this problem arises purely because they mostly studied Confucianism, but adopted the aristocratic collegiate system.

As a result, both systems did not learn the essence, but instead learned all the dross, and as a result, no matter what they did, there were people who opposed it for the sake of opposition.

In the history of the modern world, the officials of this small peninsula were first divided into the East People's Party and the West People's Party, and then the East People's Party split into the Southerners and the Northerners, and the Northerners split into the Great North and the Little Northerners.

This is not over, the Great North faction is divided into the Bone North faction, the Meat North faction and the Central North faction, and the Xiaobei faction is split into the Qing Xiaobei and the Turbid Xiaobei. The Nanren faction was divided into the Qingnan faction and the turbidity faction. The Westerners Party was divided into the Old Critics and the Young Critics.

In short, after either side wins, it will be further divided for power and profit, which fully embodies the theorem of infinite separability of factions in the country of the Koreans.

And under this tradition, naturally no one in the two factions wants to come out and take the blame for letting their faction lose this bite and lose power, wealth, and even life.

So now the war is still going on, but fortunately, the Great Song Dynasty did not continue the war after achieving the strategic goal prepared in advance, but directly began the post-war recovery work in the recovered areas.

The same was true at sea, where the vast majority of the destroyed navy of Goryeo attempted to disrupt the naval communications of the Great Song Dynasty by sending all the ships to the sea by sea privateering, but in the face of a large convoy formation was no different from sending them to death.

Even so, Liang En and the others still maintained a high level of vigilance when they entered the war zone, avoiding losses that could have been avoided because of carelessness.

"How's the new telescope?" With a gust of wind, Liang En appeared behind Ao Lei and asked.

"It's very good to be able to reach the level of a medium-sized or even a large telescope in a much smaller size." Ao Lei put down the binoculars and turned her head and said. "It's just a pity that the mirror needs extraordinary strength to complete."

"The main thing is that some chemicals require the intervention of cultivators to manufacture, but I think with the gradual development of the imperial court industry, these things should be able to gradually turn into items that ordinary people can make."

Liang En smiled a little helplessly, he knew that as long as there was transcendent intervention, the cost of anything could not be reduced, but many times when the technology was not enough, he could only rely on cultivators to make up.

Fortunately, the technology on the side of the imperial court is also progressing rapidly, so it won't take too much time to convert these things into technologies that ordinary people can complete.

"Fortunately, the optical instrument itself is expensive, so these things can still be done if they want to recover the cost, if you sell it, it is best to make it clear to them, otherwise it will be very troublesome to reduce the price in the future."

After a while of discussing the future direction of the island's most important optical instrument factory, the ship left the danger zone without incident. Just as the two of them were about to go back to the cabin to rest for a while, a black dot suddenly turned out from behind a desolate reef nearby.

"One, two, three—" After the first boat turned out from behind the reef, six more boats rushed out from behind the reef.

But after a few seconds of observation, Liang noticed that the brand-new-looking sailboats were very clumsy, and did not even look like an experienced person driving them.

Especially after the entire fleet rushed out from behind the reef, the leading ship looked as if it had just spotted Liang and the others and tried to turn around, but quickly collided with the other ships.

"Let's go see what's going on." The unexpected appearance of the fleet made Liang En vigilant, so he commanded his own ship to rush towards the ships that suddenly rushed out.

He didn't have to worry about what the ship that suddenly rushed out of the mountain was going to do it, after all, there was only that reef in the sea that could be used as a concealment, and everything else was an unobstructed and calm sea.

As Liang En's flagship approached, the chaos of the seven ships increased further, and when they finally saw Liang En's ship appear, they even lowered their sails neatly.

At this time, Liang En also found that the other party's seven ships were all Goryeo sailing ships, and there were not even oars, and lowering the sails in this situation was actually putting himself in a position to be slaughtered by others to show surrender.

He only found out when the boat driven by Liang En approached the other party. There were not the imaginary militants on these Goryeo ships, but a group of Goryeos dressed in white.

Completely different from the movies and TV dramas filmed by the Korean people in the modern world, the traditional costumes of ordinary people in Korea are not colorful at all, but white water, so they are also called the people in white.

And now the clothes of the Korean people on the ship are not even really white, but purely undyed clothes are worn on the body, and the clothes are in tatters, which fully shows the meaning of the word "unclothed".

At the same time, these people as a whole look a little strange, for example, there are old people with gray beards and babies in swaddling clothes, and the ratio of men to women is almost 1:3.

"What's going on with you?" After feeling the spiritual power on the other party's ship, Liang En asked loudly.

In this era, those who could sail boats were all cultural people, and for the cultural people of Goryeo, Chinese and Chinese characters were compulsory subjects, even if they could not write Chinese characters, they would definitely speak Chinese.

"My lord, we are not enemies—" After listening to Liang En's inquiry, a gray-haired old man on the ship knelt down to Liang En with the people on the boat, and then talked about what was going on with them.

It turned out that they were Goryeo shipwrights, who had been building new ships for rework since the last fiasco of their sailors.

But the problem is that the money and food issued to them by the Goryeo court are insufficient, and there is not much left after layers of deductions and exploitation, and they can't even support themselves, let alone support their families.

They tried to petition, but were killed and wounded by the shipyard thugs, and threatened that if they did not get the ship out on time, the master would be executed, and the others would be beaten.

So in desperation, they could only choose to take risks and seize the opportunity to flee after the ship was built and not yet delivered.
