Jia Yi originally thought that Li Er was the first Tang Dynasty person to see the entire world map, but he didn't expect that because of Liu Renliang's insistence, the world map was the first to be presented in front of Liu Renliang.

A small piece of paper was spread out on the table, and before Jia Yi began to explain, Liu Renliang's eyes widened as if he had seen a ghost, and pointed to the extra land on the paper and asked Jia Yi: "My Datang is the largest land in the world, and there are few countries around it, Tubo, Tianzhu, Gaochang, and Huifu, but even if these countries are put together, they can't be as big as the territory of my Datang, what's going on with your extra land, isn't it your graffiti?" ”

Jia Yiqiang resisted the urge to slap Liu Renliang to death with one palm, pointed to the American continent and said to him: "The land in this place is several times larger than that of the Tang Dynasty, and although there are human beings in this place, most of the area is still barren, the most important thing is that there are many rare things here, I want to say that there is a kind of grain in this world that can produce more than 3,000 catties per mu, do you believe it or not?" ”

Liu Renliang's eyes, who had just recovered to their original state, suddenly widened again after hearing Jia Yi's words, the land that can produce a thousand catties of grain in the Tang Dynasty is already considered fertile soil, three thousand catties, I can't even think about it, but Liu Renliang's understanding of Jia Yi, he has never had any moisture when he speaks, since he said it, then there must exist in this world, ordinary wheat and rice must not have such results, then the only problem appears in the grain itself, in other words, it should be a brand new grain, It's just that he has never seen it yet.

"You are also surprised, the grain I am talking about is called potatoes, it grows on this land, even if our giant ship can be invincible along the coast, but if you want to go to this land, it will not work without transformation, which is why I must transform the original giant ship that was originally used."

Jia Yi's reason is very sufficient, feudal society has always been based on agriculture, and the grain has never been enough to eat, even if the giant ship can get a lot of food back from Lingnan every year, but the people who are still starving in Datang are still countless, if they really find this kind of grain that can produce 3,000 catties per mu as Jia Yi said, then the people of Datang will no longer have to worry about hunger.

It's this small reason, not to mention him Liu Renliang, even the cautious His Majesty Li Er, after getting Jia Yi's assurance, will agree as soon as possible, no one can remain calm in the face of such a huge temptation.

"What you said is true?" It's just that this reason is too shocking, so much so that Jia Yidu has already said it to this point, but Liu Renliang still looked incredulous, and finally asked the doubts in his heart again.

Jia Yi nodded with a wry smile on his face and affirmed again: "As long as you can transform the giant ship into a sea ship that can reach into the open sea, you will have the opportunity to come to this continent and find potatoes, a grain with an astonishing yield per mu." ”

Jia Yi's words have all come to this, if Liu Renliang still insists on not letting the giant ship move, it will be simply against the people who are still hungry in the entire Tang Dynasty, without any hesitation, he directly slapped his thigh, agreed to Jia Yi's request, and promised Jia Yi to fully cooperate.

Since Jia Yi is ready to be a carefree marquis, he really doesn't plan to manage these things too much, so he told him what he needs Liu Renliang to do, and finally in order to avoid the navy from doing nothing, Jia Yi even proposed a new concept of the Marine Corps to Liu Renliang, which made Liu Renliang's eyes light up again, and sat on the chair to discuss with Jia Yi what the so-called Marine Corps is.

The transformation of the giant ship is not very smooth, at least the model that belongs to the Galen ship that exists in Jia Yi's mind is not very perfect, so the process of transformation is not so much an integration of the giant ship and the sea ship through Jia Yi's own memory, but rather a manifestation of the collective wisdom of all people here, as long as people with a little experience will say their precautions about the sea, and then get the most intuitive embodiment on the giant ship.

It only takes half a year to build a giant ship in the dock, but it took a whole year for the transformation of the giant ship to be completed, although no one knows if this thing can survive in the deep sea before testing the waters, but in the face of the crystallization of the wisdom of the big guy, everyone is full of confidence in this new giant ship at the same time.

The Galen ship, which dominated the sea for hundreds of years after the beginning of the Age of Discovery, must have its long-term necessity, although Jia Yi is not very clear why the real Galen ship has such achievements, but this does not prevent him from thinking about the new giant ship in many directions.

In order to arm the first deep-sea giant ship, Jia Yi equipped all the weapons he could find on this ship, the ship that already looked very powerful, and then equipped with these weapons, it suddenly became a war fortress on the sea, just the bed crossbow installed on this giant ship, let everyone believe that whoever encounters such a big guy can only run for his life.

When the deep-sea giant ship was completed and fell into the water, Liu Renliang issued an order to go to the sea, and only if it could successfully stay at sea for seven days could it be proved that the deep-sea giant ship had the ability to survive at sea.

All kinds of supplies were loaded onto the deep-sea giant ship as quickly as possible, and in order to ensure that the sailors would not be dying of thirst or starvation at sea, Jia Yi prepared a large amount of fresh water and food for them.

Soon the deep-sea giant ship was ready to leave the port and go deep into the deep-sea area, originally there was no need for such an experiment to be personally participated in by a third-grade master like Liu Renliang, but this person insisted on being on the deep-sea giant ship and witnessed the performance of this giant ship on the sea.

In this regard, Jia Yi can only be speechless, the most naval commander, this is Liu Renliang's duty, as the general of the Tang Dynasty, this is Liu Renliang's obligation, for such people, Jia Yi can only admire or admire, as for whether they can survive on the vast sea for seven days, this can only be resigned to fate.

When the giant ship was transformed, the work of the hot air balloon was also in full swing, a hot air balloon is Jia Yi's harvest in the past two years, and every hot air balloon that can be successfully raised will inevitably be able to play a role in the near future, Jia Yi deeply believes in this.

Jia Yi here is carrying out the renovation of science and technology, the development of other places has not been idle, the heyday of Zhenguan's rule has unfolded over time, the land of Hebei is now full of cotton, or how to say that the master is in the folk, the cotton that could only be used to play cotton wool was spun into cotton thread by someone with a spinning machine, and with cotton thread it means that there will be cotton clothes coming out.

Compared with linen and silk, the role and benefits of cotton clothing are very obvious, as a pure cotton thread, good water absorption and air permeability, can make people wearing cotton clothes feel extra comfortable, and then cotton clothes are stuffed into cotton wool, the warmth effect is much better than linen cotton wool.

Due to the existence of the Sifang grocery store in the land of Sichuan and Shu, all kinds of famous and high-quality specialties began to be transported from the land of Sichuan and Shu, and then turned into money and grain and returned to Sichuan and Shu, and the life of the people of Sichuan and Shu became much better for a while.

As for the economic development in other places, it is also progressing steadily, although it is not as fast as here in Shanghai, but the number of wealthy people has begun to become more and more.

I don't know if the prosperity of the people of the Tang Dynasty stimulated the nerves of those subject countries, or whether they felt that they could have better development after breaking away from the Tang Dynasty, in short, after years of operation, Gaochang finally got tired of the days of pretending to be his grandson, and shouted at the Tang Dynasty.

"I don't listen to what you say, I don't do what you tell me to do." It is a sentence that Gao Changguo Ju Wentai has been repeating in his heart, and he believes very much that with the geographical location where they are singing, even if the cavalry of the Tang Dynasty comes over, it will be difficult to attack their towering city, not to mention that there will be many difficulties and obstacles on the way here, which is enough to make ** suffer a lot.

It's a pity that Ju Wentai forgot a very important thing, that is, although Gaochang City is located in a dangerous place, it is easy to defend and difficult to attack, but this is only for the Tang people, for the people on the grassland, even if Gaochang is poor and bad, but there is always a way to reach Gaochang City.

Hou Junji has been stationed on the grassland for many years, although he is still not very familiar with the terrain of Gaochang, but he is very clear about the temperament of the Xue Yantuo people, just a little punishment, Xue Yantuo people obediently took Hou Junji through the path to the city of Gaochang.

Ju Wentai, who was enjoying the song and dance, peed his pants in fright when he saw Hou Junji's general flag, he couldn't imagine that ** came so quickly, I don't know if it was because I drank too much wine and had high blood pressure or what, I couldn't afford to get sick directly, and my body was hot and cold, and he died within a few days.

The war started very quickly, and ended quickly, with the surrender of Ju Wentai, Gaochang's resistance became very weak, although there were still some resistance forces, but under the iron hooves of Hou Junji's army, no one could stop the edge of Hou Junji's horse lance, and for a time it was defeated and retreated, until the last resistance force hated the spot.

Since then, Gaochang has become the territory of the Tang Dynasty in an unremarkable manner, and it happened that this battle was fought by Hou Junji, and Li Er let Hou Junji directly govern here.
