Slowly walked in the direction of the Yangtze River Delta according to the original road again, what he saw along the way but once again made Jia Yi's heart full of deep joy, regardless of whether he walked through Luonan, or the Sichuan and Shu generation, the lives of the people have become richer, and there are people everywhere who are full of gratitude to Jia Yi along the way to send all kinds of things to express their gratitude to Jia Yi, for which Jia Yi has no excuses are all accepted by people, this is the people's gratitude to him, but also the people's affirmation of him.

Sifang grocery stores are now all over every place that Jia Yi has visited, and the goods contained in them are even more varied, all kinds, not to mention, there were too many restrictions in the Tang Dynasty, and it is impossible to do it as readily available as later generations, but what you eat is not much different from later generations, regardless of whether it is the fruit of the south or the season of the north, as long as your people can eat, you can basically find it in the grocery store.

Due to the existence of grocery stores, the people of the entire Datang know that there are so many delicious foods that can be eaten in this world, and at the same time, they also have a strong interest in the scenery and humanity of other places in Datang.

The rapid opening of the Sifang grocery store made Jia Yi have to develop a career that should not have appeared in Datang, that is, logistics, whether it is to deliver goods for himself or to help others deliver things, logistics will be very practical and convenient, especially the safety is very guaranteed.

Guarded by exploding arrows and regular soldiers, it is believed that as long as they are not rebels, they will not choose to attack the army armed to the teeth.

The things he saw along the way also opened the eyes of Wu Yuanhua and Yang, who were going to the Yangtze River Delta with Jia Yi, Wu Yuanhua, as a young girl, was always full of interest in the novel scenery around her, and felt that her relationship with Jia Yi had been good to a certain extent, and she would ask Jia Yi directly when she saw anything strange.

"Sir, why do you say there are fish ponds next to these mulberry trees?"

This is already Wu Yuanhua's thirteen questions to Jia Yi, Jia Yi only has a bitter smile on this, of course, this kind of inquiry has also shortened the distance between the two a lot.

"In the future, you will call me eldest brother, it is too raw to call the lord, as for the fish pond there will be a fish pond next to the mulberry tree, it is because the fish pond has fertile soil, which can be used to promote the growth of the mulberry tree and provide enough fertilizer for the mulberry tree, and the two are so close to each other that it can be easily fertilized."

When Jia Yi told Wu Yuanhua about this, Jia Lu, who was sitting next to him, also nodded, God knows if he understood what Jia Yi said, and even nodded his head like Wu Yuanhua, and everyone in the carriage burst into laughter.

"Don't laugh, my dad used to tell me that it's a manifestation of the ecosystem, and I know that ginseng feces are used to feed crucian carp in the pond." Jia Lu is now six years old, and he is a half-grown child, and Jia Yi will tell him some modern knowledge when he is bored, and of course, the most is to let him read and read when he is interested.

Looking at Jia Lu's solemn face, everyone in the carriage consciously closed their mouths, but everyone's body twitched involuntarily, obviously holding back a smile.

Seeing this, Jia Lu sat down on the car again with satisfaction, and began to play with the building blocks that Jia Yi made for him, but playing this thing on the carriage is really a test of a person's patience, the building blocks that have just been piled up will be re-toppled because of a small bump, so that people have to start again, if there is no strong perseverance, I believe that the building blocks will be thrown out of the car, or the carriage will be dismantled into pieces.

In late autumn, it has begun to show a little chill, but as everyone continues to travel south, although the temperature will also decrease, it is definitely not as fast as it decreased in Chang'an, and sometimes you can even see dark green plants, which makes everyone happy.

The half-month trek finally came to an end, and when people stepped off the boat, there was a huge gathering place where thousands of families had settled, making the Yangtze River estuary, which was originally just a small fishing village, become the scale it is now.

Since Jia Yi left, the person responsible for supervising shipbuilding here has become Liu Renliang, and he has heard of Liu Renliang's name Jia Yi, if you want to say that the mirror of the Tang Dynasty is Wei Zheng, then Liu Renliang can definitely be regarded as another mirror, but it is a pity that he was born at the wrong time, and he was not able to catch up with Li Shimin's time to conquer the world, which led to his upright temperament not being able to get the maximum performance.

And after Jia Yi accidentally met Liu Renliang, he thought of Liu Renliang becoming a famous admiral of the Tang Navy when he was in his sixties, and recruited him as soon as possible, and after success, he directly arranged him in the dock.

With the arrival of Liu Renliang, the originally quiet and peaceful dock suddenly became a grievance, everyone who worked in the dock expressed a very huge dissatisfaction with Liu Renliang's management method, and Jia Yi's kind of character as long as it does not delay things, everything else is completely different, Liu Renliang requires everything to be very strict, which directly makes the originally very free people suddenly feel like they are bound to a huge shackle, and there is no public resentment before there is a ghost.

Seeing this situation, Jia Yi immediately relieved and handed over the entire dock to Liu Renliang's hands, Jia Yi believed that as long as Liu Renliang supervised here, there would be absolutely no problems in the dock, and he could rest assured.

In fact, just as Jia Yi thought, Liu Renliang did not disappoint Jia Yi, this man who is now in his thirties still maintains his old upright style, and will be meticulous in completing everything, and the ship built makes Jia Yi very relieved.

When Jia Yi saw Liu Renliang again, he found that his face was straighter, and the people around him who saw Liu Renliang would take a detour as soon as possible, and they didn't have the idea of wanting to come up and say hello when they saw Jia Yi.

Maybe it's because he's used to it, Liu Renliang didn't have any anger about it, and after seeing Jia Yi, he bowed to worship after seeing it, regardless of whether Jia Yi stopped it or not, looking at Liu Renliang who got up from the ground, Jia Yi's face was full of wry smiles.

"Brother Liu, I've said it eight hundred times, there's no need to be so angry between us, besides, if there is Chang'an here, where can there be so much etiquette."

"Etiquette should not be abolished." Liu Renliang's answer was always so straightforward, even if he saw Jia Yi, there was obviously a smile in his eyes, but there was no smile on his face, which made Jia Yi, who saw all this in his eyes, feel very painful.

"Whatever you want, whatever you like, it's you and not me who salute anyway." Jia Yi rolled his eyes at Liu Renliang for a long time, and finally pulled Liu Renliang into the courtyard that had been built here a long time ago, and after coming to the living room and sitting down, the two began to talk again.

"Brother Liu, I heard that there are ten giant ships that have been built in our current world?" The last time he passed by here, Jia Yi saw only seven or eight giant ships, but he didn't expect that it had only been a little more than a year, and there were ten more giant ships.

"Well, there are ten ships, two of which travel to and from Lingnan all the year round and collect some specialties and surplus grain from the coastal areas they pass by, and the remaining eight are anchored at the mouth of the Yangtze River all year round to carry out necessary naval training, but they dare not go deep into the open sea, for fear of capsizing."

There is no problem with the giant ships swimming along the coastline, but if they enter the deep sea area, whether they can sail normally, even Jia Yi does not have much confidence, this time he came here to transform these giant ships, and the other is to equip these giant ships with weapons, at the beginning of the battle at sea, these giant ships can become a sharp knife on the Tang Sea.

In fact, in this era, let alone the Tang Dynasty, there is no country in the world that can build ships that sail on the sea, even if these giant ships built by Jia Yi, it is okay to run along the coastline, if they are allowed to enter the deep sea, they may sink into the bottom of the sea at any time, this is not to say that Jia Yi is not confident in this, but he really knows that the ocean is not a joke.

The real Age of Discovery also needs to transform these giant ships in an all-round way, otherwise the dream of using ships to dominate the world is still to be considered.

"Brother Liu, I won't be able to leave for a short time this time, it just so happens that the navigation experiment of the giant ships has officially ended, and I am ready to start transforming these giant ships to make them sea ships that can really adapt to the sea, this is a complicated and time-consuming process, if you don't have anything particularly important, just stay here and help me."

Liu Renliang said in a local dialect that the stones in the pit are smelly and hard, that is, Jia Yi knows where this person's temper is suitable, and it is impossible to use him if he is replaced by someone else, so Jia Yi's words are completely polite, because he also knows that Liu Renliang really has nowhere to go.

However, since he gave someone an errand, if he did not have a corresponding official position, it would inevitably make the family feel uncomfortable, so Jia Yi had already asked for a decree before he came, and directly named Liu Renliang as the general of Haiwei, and his official position was one level lower than Jia Yi, from the third grade.
