Marriage is a political show no matter when it is an act of sacrificing women for the interests of both parties, Jia Yi expressed great disdain for this, but this kind of thing is not right or wrong at all, rationally speaking, it is cost-effective to exchange a woman for a place or even a country for years or even decades of peace, but is there anyone who thinks about the problem from the perspective of this woman, after she marries, she will definitely not be able to divorce back at the beginning of the war, so what kind of treatment will she receive at that time, No one can guarantee this.

Even though he knew that Li Xueyan, that is, Princess Wencheng, had received very good preferential treatment after marrying into Tubo, but he could entrust the fate of the Chinese people to others, he still couldn't be accepted by Jia Yi, looking at Li Xueyan's somewhat reluctant eyes because she was about to separate from herself, Jia Yi was even more determined to keep her in Datang.

Even if Jia Yi brought gunpowder, a forward-facing substance, to the Tang Dynasty, but if you want gunpowder to play its due role, it will take a long time to explore and develop, originally Jia Yi didn't want to participate too much in the process of gunpowder research and development, after all, only with a certain amount of knowledge accumulation, can we research more advanced things on this basis, and the fault line of knowledge is sometimes more able to hinder the pace of human progress than from the new discovery of this knowledge.

For the sake of Li Xueyan, Jia Yi decided to personally promote the progress of the times, and it happened that the giant ship had been completed, although the bed crossbow had been installed on the giant ship, a weapon with great power in Datang, but compared to the bomb, a weapon of war, it was completely different, so Jia Yi decided to develop a bomb.

In fact, there is basically not much difference between the principle of bombs and exploding arrows, the only difference is the amount of ammunition used, so as soon as Jia studies the bomb, it is very fast and simple.

Sitting on the boat, almost everyone was admiring the scene in the sea with curiosity on their faces, but Jia Yi got out the drawings for the production of the bomb, and when he arrived in Lingnan, he would start to make it.

Because Jia Yi was not very sure that the giant ship he had built could withstand the huge wind and waves on the sea, so for the sake of safety, he let the giant ship go along the coastline, it can be said that the mainland has not disappeared from his sight, the only difference is that sometimes it is closer and sometimes it is farther, and it only took half a month to come from the Long Sword Triangle to the Pearl River Delta.

With the passage of time, it stands to reason that the temperature should be lower and lower, but the people on the ship did not feel the obvious change in temperature, and even felt that the temperature was still rising.

The fish in the sea have even undergone some changes, from a relatively single species at the beginning, to a variety of fish now, and even when Jia Yi appeared on the bow of the boat, he saw a few dolphins, which was really not an ordinary luck.

The Lingnan area is located in the southernmost part of Datang, and Jia Yi, who has never been to Lingnan by boat, does not know where the destination is, so every once in a while, Jia Yi will find a fisherman who goes out to fish at sea to inquire about the current location, and then adjust the route according to the news he gets, and continue to move towards the southernmost part of Datang.

After many investigations, Jia Yi finally came to the center of Lingnan, that is, the so-called Pearl River Delta area, compared to the environment of high-rise buildings developed in later generations, this kind of natural scene full of mountains and forests, full of verdant greenery, is enough to make people feel relaxed and happy.

Feng Ang received the news from Jia Yi a long time ago, so he sent his second son Feng Zhiang to wait at the Pearl River Wharf.

Feng Zhiang is just twenty this year, it is the age of young and vigorous, as the second son of the Lingnan Emperor, from childhood to adulthood, he grew up in the compliments of the people around him, before Feng Ang had not taken refuge in the Tang Dynasty, someone had persuaded Feng Ang to break the soil and seal the king, Feng Zhiang, who was not very old at the time, also tried his best to persuade his father after hearing the news, but the result was a stinky beating, Feng An's move left traces of resentment in Feng Zhiang's heart at that time, because he did not have any good impression of the Tang people.

Later, someone framed Feng Ang and said that he wanted to rebel, and even Li Er at that time had already ordered troops and horses to be ready to march towards Lingnan at any time, in order to stabilize Li Er, Feng Ang directly let his son enter the steel production and become a hostage.

Feng Zhiang has a lot of reluctance in his heart for his brother being sent to Chang'an by his father as a hostage, but he already has some thoughts, and he clearly knows that even if he says more, it is impossible to influence his father's decision, but his resentment towards the Tang people has become deeper.

Now that Jia Yi has arrived, Feng Ang is the biggest chief of the Lingnan tribe after all, not to mention every day, things are also very complicated, and there is almost no chance to get out, so he sent his second son over to greet him.

Feng Zhiang was lying in the post station by the sea, eating all kinds of seasonal fruits under the clothes of the maids beside him, his face was full of enjoyment.

"Second Young Master Qiqi, there is a fleet that has entered the Pearl River, and since there is no flag on the ship, I can't judge who is coming, and I ask the Second Young Master to decide."

Feng Zhiang heard the return of his subordinates, but his eyebrows couldn't help but provoke, the Pearl River is often invaded by pirates, but basically it is mostly a rabble, and before it is close to the sea, it will be snatched by the Feng family with the boat, and now someone has entered the Pearl River again, I don't know if it is Jia Yi and others who were explained by his father, but it doesn't matter, it doesn't matter if it's Jia Yi or not, because whether it's Jia Yi or not, he plans to catch all the people in the future, and play with it first.

"Light up the warship, go out with me, trespass on my Pearl River, and look for death."

Feng Zhiang got up from the bed in a hurry, grabbed a handful of the fruit bowl held by the maid, and walked outside while eating, the rippling Pearl River appeared at his feet, and hundreds of warships docked in turn in the nearby dock.

With Feng Zhiang's order, countless men and horses quickly boarded the battleship, and then dozens of warships quickly sailed towards the mouth of the Pearl River.

Jia Yi, who stood on the boat and looked at the surrounding environment, discussed with his three daughters-in-law the changes in these environments, as well as the differences from the northern environment, while checking what species of swimming fish kept jumping out of the water in the sea.

Jia Lu, who is already more than a year old, has been able to say simple words, under the protection of the nurse, lying on the side of the boat and watching the blue waves under the boat, showing unusual excitement, pointing to the swimming fish jumping out of the water on the sea and saying something.

Just when the family was enjoying a rare good time, an alarm sound came from the lookout.

"There are dozens of unidentified ships ahead, each loaded with soldiers in armor, without flags, and it is difficult to determine who they belong to."

The sea is not as good as the land, if you are defeated, you can escape as long as you have a direction, the sea is full of seawater, as long as you are attacked on the ship, then what awaits them will be the end of the dead ship, before you determine who the person is, Jia Yi does not want to take this risk, and immediately ordered everyone to prepare for battle.

Soon all the bed crossbows were wound, and the various hand crossbows were loaded with arrows, and if they noticed something wrong, they would shoot all the arrows that had been loaded as soon as possible.

"Stop coming, report your name." The loud voice shouted at the other party as a ship from a long distance, but he shouted several times in a row, but still did not get any response, and the dozens of ships rushed towards the huge ship that was swimming in front like crazy wild dogs.

"Archery warning."

With Jia Yi's order, three bed crossbows were shot out, stirring up three waves on the sea, only two or three meters away from the first ship of the opponent's fleet, these three arrows are the target arrows to measure the range, and they are also warning arrows to warn, if the people who come do not make any sound, Jia Yi will attack when their ships enter the range.

In fact, when Feng Zhiang saw the huge figure of the giant ship from afar, his heart was already full of deep shock, as a person who often haunts the sea, there is no one who knows better than him what the huge ship at sea represents, so the first thought that appeared in his mind was to seize this big ship, and his brain was running rapidly, thinking of various ways to board this big ship.

Feng Zhiang never thought about how much achievement people who lived in Chang'an, the Tang Dynasty, who were good at land warfare, could achieve at sea, so he never thought about what kind of attack this big ship would have, even after Jia Yi sent out three standard arrows before, he still didn't care about it, and once again ordered his sailors to speed up and drive towards the giant ship.

Seeing that there was still no response, for the sake of the lives of his relatives on the giant ship, Jia Yi did not hesitate to give the order to attack directly, the bed crossbow was loaded with a special burst crossbow arrow, dragging the shining sparks and flying directly towards the ship that entered the range.

Then a burst roar sounded quickly on the opponent's ship, and a dazzling light burst out from the opponent's ship, and when the light dissipated, those ships had become a sea of fire, and the people who were still alive chose to jump ship, although the ship could continue to be used if it was treated now, but as long as you looked up at the flying arrows above your head, the people who survived were all dispelled from this unrealistic idea.

Jia Lu was brought into the cabin by the nurse at the beginning of the battle, and now the child is too young to see such a tragic scene.
