Two Grand Canals were built, and Tao Ying had a fertilizer factory open in each county, and then the fertilizer produced was supplied to the county's fields. Chemical fertilizer is sprinkled into the ground, the land is fertile, and with water irrigation, the yield per mu and one season is nearly three or four times more than before.

In Tao Ying's three-year plan, the first three-year plan is to defend Xuzhou and solve the problem of food and clothing. While vigorously developing agriculture, in order to be able to defend Xuzhou City, the development of military is also a necessary means.

Tao should ask the generals of each county to step up their training, there can be not many soldiers and horses, and they must be an elite army. At the same time, Tao Ying began to urge the Mechanics School and the Gunpowder School to continuously improve their equipment. The coal in the Mining School has also begun to be excavated, and the Smelting School has also developed the steelmaking technique little by little.

Time flies, when the winter snowflakes are falling in Pengchengguo again, the Gunpowder School of Taoling Town has improved the gunpowder, although it is not as powerful as the later generations, but according to Tao Ying's formula, it is no problem to make some ** earth cannons.

Manufacturing**, such a single-arm weapon, costs a lot of money, and it is not easy for soldiers to operate. Therefore, Tao Ying temporarily terminated the development of **, and instead focused on the development of earth cannons. In order to be able to quickly develop the cannon, Tao Ying personally participated in the development of gunpowder.

In winter, the snow was flying, and the spies came to hear from everywhere that Yang Feng fought against Cao Cao in the Luoyang generation, Cao Cao defeated Yang Feng, and Yang Feng went south to take refuge in Yuan Shu.

In October, Zhang Ji led his troops to attack Nanyang and was killed, and his son Zhang Xiu led his subordinates. One news after another, it seems that it has little to do with him, and Pengcheng is still developing rapidly on his own reform road.

The winter snow is still melting, and January 197 is coming. In January, just after New Year's Day, Tao Ying got up early, so this is a particularly important day.

After nearly half a year of research with the Gunpowder School, the Gunpowder School finally improved the gunpowder and invented the first cannonball. The Taoling Smelting School also built a high-temperature furnace and cast steel at high temperatures such as coal, and built the first cannon according to the drawings.

Tao Ying named him the Taoling generation cannon, and after the cannon was made, it was scheduled to be experimented on this day. Xiaohuan got up early to help Tao Ying get acquainted, and Tao Ying took Sun Shao and Zhou Tai to the school to test the gun.

The artillery field is set up in the mountain nest of the military district of Taoling Town, which is also the address of the gunpowder school and the smelting school. In a flat place that has been reclaimed, a gun carriage is fixed with wood on the ground, and a Taoling generation cannon with a length of nearly three meters and a diameter of nearly 30 centimeters is erected here.

The early morning sun was a little warm, the snow in Taoling had not completely melted, the teachers and students of the gunpowder school were there early to debug the explosives, at ten o'clock at noon, when Tao Ying appeared in the artillery field, after nearly half an hour of debugging, the fuse was ignited, and a burst of sparks went towards the tail of the cannon.

Suddenly, there was a loud bang, as if a landslide cracked, and a stone was blown away nearly thirty meters away from the Taoling cannon. The avalanches on the ground were everywhere, and the broken stones made the collapse far, far away, and a stone almost hit Tao Ying's head, which surprised Zhou Tai next to him!

Soon after the cannon sounded, suddenly Tao Ying slapped his face and shouted excitedly: "It's successful, it's finally successful!" ”

Although the attack distance of this generation of artillery is particularly close, and the operation is extremely complicated, it is not easy to aim, and it is easy to explode, and it takes half a day to replace the shells.

It's just that after a few shots, you have to cool the barrel with water before you can continue to use it, but all this is a good sign!

On the day of the successful test firing of the Taoling cannon, Tao Ying ordered that this day be positioned as an artillery day, and the first artillery school in the late Han Dynasty was established in the mountain nest of Taoling Town.

In order to establish the artillery school, Tao Yingxuan combined the entire gunpowder school with some relevant teachers and students of the Taoling Mechanical School and the Smelting School.

After a spring of preparation, when the time came to March, the Taoling Artillery School was officially listed for enrollment. There are three departments under the artillery school, the first is the gunpowder class, the second is the artillery production class, and the third is the artillery class.

The artillerymen recruited from their own guards to learn from the right people, who would have to train more artillerymen in the future and study more accurate design methods on their own.

After the establishment of the artillery school, on the other side, the mechanical school and the steam engine were gradually invented. Truckloads of coal were transported to the mechanical school, and when the coal was ignited, a large cauldron of boiling water boiled, and the boiling water pushed the lid of the pot up, creating power.

The first industrial revolution seems to be about to begin in Pengcheng!

With the initial appearance of the steam engine, Tao Ying wanted to equip it for his own military use first. And how to apply the steam engine to the military?

After thinking about it for a long time, Tao Ying finally formulated a new policy, that is, to equip Taoling artillery and steam engines on warships within three years. Then continue to widen the river from Juye to Jiangdu, so that their new warships can truly take on the dream of defending Xuzhou.

When spring arrives, the common people start to get busy. At this time, a message suddenly came from Pengcheng, saying that Huainan had sent an envoy to ask to see Tao Ying.

The messenger of Huainan? Tao Ying was a little puzzled, this Yuan Shu and himself can be regarded as mortal enemies, he watches the land of Xuzhou every day, why is it so good to come here this time, is there something to ask for himself?

The envoy heard that Tao Ying was not in Pengcheng, and came to Taoling Town to visit Tao Ying with gifts. During this period of time, Tao Ying was busy with how to improve the steam engine, and when the envoy arrived, Tao Ying washed his hands and met the envoy in the main hall halfway up the mountainside.

At ten o'clock in the afternoon, inside the main hall, looking at the simple hall, this hall was hundreds of times inferior to Yuan Shu. After the envoy sat down, Tao Ying accepted the gift and asked, "Why did Lord Liu come this time?" ”

The messenger replied, "It's to bring good news to Xuzhou!" ”

At the mention of good news, Tao Ying laughed, who doesn't know that this Yuan Shu has a bad heart, what good news can he bring to himself!

Seeing that Tao Ying didn't believe it, the envoy hurriedly added: "If Cao Cao is in power in Xuchang today, the Han family has long existed in name only. My lord is the fourth and third dukes, and he sits on the land of Yangzhou, the people live and work in peace and contentment, and the scholars are vying for refuge, which is really the destiny of heaven. Now the jade seal is coming to my Huainan city, it can be said that the mandate of heaven is here, so my lord obeys the will of heaven in Huainan to ascend the throne, and the general is specially named the hussar general, and the Xuzhou Mu is sealed, and the second son said that this is good news? ”

After the envoy finished speaking, he looked at Tao Ying quietly, Tao Ying was silent for a while, but Sun Shao and Zhou Tai next to him were already furious. Sun Shao stood up and scolded bitterly: "Yuan Shu Pifu, the hereditary grace of the Yuan family, I don't want to serve the country but want to spy on the throne, I really don't know how to be ashamed, and I lose the face of the fourth and third princes of the Yuan family!" ”

After Sun Shao finished speaking, the envoy retorted: "Since the rebellion of the Ten Standing Servants, Dong Zhuo and Cao Cao have occupied the court, the people are miserable, the Han family has exhausted its qi, my lord obeys the will of heaven, is it as Mr. said?" ”
