If agriculture is the foundation of the country, then commerce is the productive force that promotes the development of agriculture. The reason why the common people are able to guard the fields in the wind and rain is more because they have not yet solved the problem of food and clothing.

And once the Quyuan plough is promoted or the southern wilderness is opened, it will bring a lot of food to Datang. At this time, commercial circulation is extremely important.

It is normal for Tang Jian to feel uneasy when he sees the people of Jingyang County planting vegetables and vegetables. And in order to dispel his doubts, Qin Ze decided to take him to the Agricultural Department in person.

Among the six departments of Datang College, the largest is the Department of Agriculture. More than 100 acres of fields surrounding the Jinghe River can be said to be experimental fields of the Department of Agriculture.

Because of Qin Ze's support, the breeding of the Agricultural Administration is carried out all year round. Whether it's winter or autumn, the crops in the fields are always growing.

At the beginning, Qin Ze also felt that this method was not feasible, because it meant that not only a lot of manpower would be consumed, but also a lot of material resources would be consumed. But it turns out that these people at the Department of Agriculture not only did it, but they did it well.

This is the difference between people in this era and in the afterlife, in the eyes of these people there is no efficiency and the concept of worthlessness. If it takes a year for ten people to cultivate, then directly a hundred people, and if a hundred is not enough, there will be a thousand......

In this spirit of near-foolishness, nothing can stop the hands of the craftsmen, and this is the case with this large tract of land owned by the Department of Agriculture.

Qin Ze opened the curtain of the greenhouse, and then stepped out of the way to let Tang Jian enter.

Tang Jian only glanced at it, and then completely stayed in place. It's still April outside, but the crops in front of you are green, and they look like summer no matter how you look at them.

As far as the eye could see, it was all green, Tang Jian leaned down to take a look at the crops in the field, but found that he had already begun to tassel.

"This ......" Tang Jian looked at Qin Ze with some astonishment.

Qin Ze shrugged his shoulders and smiled: "His Royal Highness the Crown Prince takes pity on the students of the Agricultural Department, so he specially asked the craftsmen to bring in six hot spring waters. It is precisely for this reason that the warmth of this place is guaranteed to be like spring. ”

Qin Ze also stretched out his hand to push the millet seedlings away as he spoke, and then dug down with his hands. Buried underneath is a pipe that leads to the hot spring water, which is why the temperature here is guaranteed.

Li You, who was busy on the side, also discovered Qin Ze and the others, so he brought a group of students over.

"Sir, now the seeds of the fifth generation have begun to mature. We have experimented with its heading rate has reached 78/10, and if we calculate from this, we can produce an average of five stones per mu. ”

Hearing Li You's words, Qin Ze just nodded. But Tang Jian on the other side slipped under his feet and almost didn't fall. Fortunately, Qin Ze's eyes were quick and he supported him.

It's not because Tang Jian hasn't seen the world, but it's really that this output is too exaggerated. He couldn't understand what the heading rate was, but he could still hear it clearly with a yield of five stones per mu.

You must know that the best fertile fields in Datang today have a yield of less than two stones per mu, and those thin fields are even more embarrassing. Therefore, a few days ago, the fields in Jingyang County were able to produce three stones, which was already regarded as auspicious. And now Li You actually said that it was five stones......

Five stones may really be nothing to Qin Ze, after all, the yield per mu in the future generations will at least double, but it is already very terrifying for Datang.

"Five stones per mu is just the best situation, if it is promoted, I am afraid it will not reach this level, at most it will only be four stones." Qin Ze looked around and sighed.

Fertilizer is still too scarce, and only Jingyang County will achieve such a high yield because of its monopoly on the silt of the Jing River. If it is promoted, where is there so much fertilizer.

Fortunately, now the Department of Agriculture has begun to study fertilizers, but there is no need to think about chemical fertilizers or anything, at most it is to study some biological fertilizers.

Tang Jian listened to Qin Ze's words, and leaned down in a daze and gently broke a few ears of millet from the ground, obviously Qin Ze's words touched him a lot. Especially the sentence "only four stones", it is simply shocking.

"The prosperous world is auspicious, and it is time for Your Majesty to see the blessings of my Tang Dynasty."

Qin Ze pursed his lips and didn't make a sound, but took Tang Jian to continue visiting. Next to the field is the greenhouse, which is used by the Department of Agriculture to hatch chicks.

When Qin Ze brought Tang Jian over, Li Ke was still lying on the ground working. Before the eggs hatch, they are screened to identify the hens. It's just that the accuracy of this method is not very high, so it has to be sorted again after incubation.

The ratio of roosters to hens should be controlled at one to six, so as not to prevent hens from laying eggs.

As for the extra roosters, they are thrown into the grass and raised. Finally, it is used to make chicken, and it is also a good choice.

Tang Jian watched Li Ke crawl on the ground, constantly blowing at the chicken's buttocks, and suddenly his beard trembled. His face changed, and he immediately broke off with a drink, and when he stepped forward a few steps, he said angrily: "The King of Shu is the body of a nobleman, and he is naturally supported by the people." How can you do such a transgression, wouldn't it ruin the reputation of the royal family! ”

Tang Jian's words made not only Li Ke stunned in place, but even Qin Ze was stunned. After a long time, Qin Ze suddenly came to his senses that the reason why Li Ke would blow on the buttocks of the chicks was just to distinguish the gender of the chicks. For Tang Jian, who doesn't know this, Li Ke's actions obviously make Tang Jian think crookedly.

"Haha......"

Qin Ze couldn't hold back any longer, and laughed out loud while holding his stomach. He couldn't laugh anymore, and Li Ke, who had been enduring it on the other side, couldn't bear it anymore. It's just that he still takes care of Tang Jian's face, so he can only turn his back and cover his mouth with his hands and smile.

At this time, Tang Jian also reacted, knowing that he might be wrong, but he looked at the chicken seedlings on the ground, but he still didn't figure out what he was wrong, and finally Li Ke forcibly explained to Tang Jian.

This time, Tang Jian was determined to make a difference, and his face also turned red, but it quickly subsided again.

There are not many opportunities to see Tang Jian's jokes, but Qin Ze can only taste them. At the moment, he also took the initiative to change the topic: "Now there are more than 50,000 birds in Jingyang County, and nearly 6,000 eggs are laid every day. If it is exchanged for the market price of Chang'an, it will be at least 12,000 yuan. In addition to raising poultry, Jingyang County now has 600 pigs and 2,000 sheep. This is all the grain of Jingyang County, and it is also the grain of Datang. ”

Tang Jian was already a little unable to keep up with Qin Ze's train of thought, and when he saw the calves one by one, he was even more surprised.

"The Military Medical Department has specially opened a veterinary department, and now it is working with the Agricultural Department to breed cattle."

Qin Ze didn't say the rest of the words, he could see that Tang Jian was completely shocked.

The development of Datang Academy has greatly exceeded Tang Jian's expectations, especially the green field, which makes him feel even more incredible.

There are more incredible things, and there are some things that he doesn't know, but it doesn't mean that Li Er doesn't know. Now the Department of Agriculture is controlled by Li Ke and Li You, and the Craftsman Department is controlled by Li Tai. The rest of the Ming Wen Department and the Military Medical Department are all sent by Li Er personally, and the Encyclopedia Department naturally goes without saying, which of the master craftsmen is not hand-picked by Li Er.

There is only one Arithmetic Department that no one cares about, in fact, it's not that Li Er doesn't want to pay attention to it, it's just that he can't find the corresponding talent.

A problem of chickens and ducks in the same cage has already stumped everyone, and who else can Li Er expect to teach these students, so he simply threw it directly to Qin Ze.

And now it seems that only the Department of Mathematics has not yet achieved results, and the other departments have already achieved fruitful results. But Qin Ze is also very clear about the importance of arithmetic, the craftsmen of the Encyclopedia Department are inseparable from arithmetic when they build bridges and pave roads, the shipbuilding and building houses in the Craftsmen's Department are inseparable from arithmetic, and even the gunpowder workshop under the Jinghe River is also inseparable from arithmetic. The reason why everyone now despises arithmetic is because these students do have a lower starting point.

If nothing else, just say that the simple multiplication formula will stump a large piece, and it will be an abacus rattle......

After sending Tang Jian away, Qin Ze wandered to the shipyard on the edge of the Jing River alone. The craftsmen here are still hammering, and this is the fourth sea ship of Datang.

There was no news, and Qin Ze did not receive news from Cheng Huailiang for nearly a year. And the only thing that can be determined is that now the location of the Wa Kingdom has been figured out, and a steady stream of warships are constantly approaching there.

When he has nothing to do, Qin Ze will come here to take a stroll. As long as you see these sea ships, you will unconsciously fantasize about the distance, where there are not only Cheng Huailiang but also Mo Xuan.

Mo Xuan and the others left earlier, calculating a year and a half, and the people of the Emperor Palace were almost about to return. Only Cheng Huailiang has no news here......

Cheng Huailiang didn't want to pass on the news, but because the eldest brother Wang of the mountain back really watched it too closely. Four months ago, the people of the Immortal Sect and the people of the Su I clan launched an attack on them on the sea. This group of ungrateful people, the first thing they thought about in the face of Tang Jun was to unite with the outside world first.

But the facts paid them a heavy price, not only did the sneak attackers disappear inexplicably, but even their sea ships were directly sunk by the "meteor".

The power of the artillery once again shocked everyone, no matter how many ships there were, it was impossible to get within a mile of the Tang army's ships. And in such a situation, it is the current stalemate.

The Wa State wanted to slowly consume the materials of the Tang Army, and Cheng Huailiang also wanted to take advantage of this opportunity to constantly put pressure on the Wa State.

And it was Cheng Huailiang's deliberate way of sowing discord that broke the last line of defense of the Wa State, so four months ago, Cheng Huailiang's sea ship approached the boundary of the Wa State.

Cheng Huailiang will not agree to either side's request to send troops, but both sides are constantly currying favor with Cheng Huailiang. And Cheng Huailiang naturally took advantage of this time to slowly find out the situation of the Wa Kingdom.

And just now, he received a letter from the eldest brother king of the mountain, and he actually wanted to board the ship in person to discuss.

This is an opportunity.

After four months of rumors, someone finally couldn't stand it anymore......
