Gongsun Kang's strategy was to take Xuzhou first. The next step he thought of was to attack the south. It's like playing Go, you take the corners first, and then fight for the center.

The Three Kingdoms are divided into three parts of the world, Cao Cao in the north, and Liu Bei and Sun Quan in the south. Sichuan is an inland basin, and Gongsun Kang is beyond his reach; But Yangzhou is coastal, and the big ships in Liaodong are currently the most advanced in the world. Gongsun Kang has no reason not to take Yangzhou.

Zhen Jiang and the others will have five months to give birth, and Gongsun Kang feels that he can use these months to travel to the south. Actually inspect the geographical situation, and bring back a few talents by the way, to reserve talents for Xuzhou.

The retinue of the departure was well chosen, and the advisers had to manage the local administration, so they would not be troubled; The generals have to guard the place, and they have to take people to raid the aliens, and they will not take them with them. The only ones to choose from are Guan Hai and Tai Shici. In addition, there is also a Sun Qian, and there are some etiquette matters that need to be handled by him.

This plan is mainly by water, and Tai Shici and his fleet must be brought. Going deep into the territory of other princes, and not making any preparations for battle, Gongsun Kang was not so naïve. So the fleet took a full 5,000 people with it. There were a lot of technical officers who drew nautical charts and surveyed reefs.

The fleet first arrived in Donglai County, Qingzhou, where supplies were replenished.

Gongsun Kang did not get off the ship, and Zhang Liao and Yang Yi came to the boat to meet him.

Speaking of Qingzhou's practical difficulties, Zhang Liao said: "There are too few people in Qingzhou, and it is difficult to feed 50,000 elite soldiers in Qingzhou. Gongsun Kang remembered the gold mines in Donglai County. In later generations, five of China's top ten gold mines were in Qingzhou, and all of them were in Donglai County.

The reason why there was no excavation before was because the gold mines were buried at a relatively deep level. Now the explosives technology in Liaodong is changing with each passing day, and it can already meet the needs of mine excavation.

Gongsun Kang comforted Zhang Liao and said: "Wenyuan, don't worry, I have already arranged for someone to go to Xuzhou to purchase grain for Qingzhou to eat." In addition, I would like to arrange manpower to mine gold in Donglai County, so that 10% of the annual output can be reserved for the local government of Qingzhou. You arrange the defense of the gold mines. ”

Zhang Liao and Yang Yi were overjoyed and thanked Gongsun Kang again and again.

So Gongsun Kang wrote a letter to Li Shanchang, asking him to send people to Donglai County to dig gold mines, and the letter said that he must send some people to the explosives battalion, otherwise it will be difficult to mine.

Gongsun Kang drew up a list and prepared to visit them separately according to geographical location.

Gongsun Kang specially inquired about the jurisdiction of Xuzhou and Yangzhou and made full preparations.

Xuzhou jurisdiction: Langya State, Pengcheng State, Donghai State, Xiapi County, Guangling County.

Yangzhou jurisdiction: Qichun County, Lujiang County, Danyang County, Wu County, Huiji County, Poyang County, Linhai County, Yuzhang County, Linchuan County, Luling County, Jian'an County.

Head south from the coastal side of Dongnae-gun. In turn, it is the Langya Kingdom of Xuzhou, the Donghai Kingdom, the Xiapi County, and the Guangling County.

The Gongsun Kang program is:

1. Langya Guo visited Xu Sheng (Langxie Ju County, now Ju County, Shandong).

2, Donghai Guo visited Mi Zhu (an old friend), this time to see how his sister Elk looks.

3. Xiapi County visited Buqi (Linhuai Huaiyin, now from the northwest of Huaiyin, Jiangsu).

4. Yangzhou visited Lusu (Linhuai Dongcheng, now southeast of Dingyuan County, Chuzhou City, Anhui Province).

5. Step trainer - Yangzhou Lujiang; Big Qiao, Little Qiao - Anhui County, Lujiang County.

6, Liu Ye -- Yangzhou governs Huainan County, this needs to let Sun Qian send Guo Jia's letter first to probe his tone.

7. Gu Yong - Wu County, Wu County. This is Cai Yong's apprentice, his own senior brother, so I put it at the end, just to visit.

The first 6 have not crossed the Yangtze River, and the last Gu Yong is about to cross the Yangtze River.

Zhuge Liang's family is still in Xuzhou, but Zhuge Liang is just a child now, is there any need to see him?

Gan Ning should be a brocade thief on the water surface of Yangzhou and Jingzhou now, I don't know if I can meet him?

Gongsun Kang thought about these two historical figures, but at first he did not list them in the plan.

The first stop is the Lang Evil Country. Gongsun Kang finally decided to meet Zhuge Liang, even if he pinched his little face and slapped his little buttocks, it was a good memory.

Langya country, jurisdiction of Langya and other thirteen cities, governance of Kaiyang (now north of Linyi City, Shandong). The territory is about the same as the south of Yishan and Zhucheng and Jiaonan in present-day Shandong Province, east of Yishui, Linyi and Lanling, north of Linshu and Junan, and east to the sea. After the Eastern Jin Dynasty, it was reverted to a county.

The Langya Kingdom has a vast area, many counties, very high taxes, gorgeous palaces, strong capitals, and important military status.

There are Yimeng mountains in the territory. The famous Battle of Menglianggu was fought here.

One thing Gongsun Kang never understands is: the current Langya country is a famous and wealthy place in the world, why has it become an old area that is poor and backward, the people can't eat, and needs relief every year?

Is it because of soil erosion?

The development of the water system in Linyi is vein-like. There are four major water systems: Yi River, Shu River, Middle Canal and Binhai, and the regional division belongs to the Huaihe River Basin.

The temperature is suitable, the four seasons are distinct, the sunshine is sufficient, the rainfall is abundant, the rain and heat are in the same season, and the frost-free period is long.

Langya has produced historical celebrities such as Zengzi, Xunzi, Zhuge Liang, Wang Xizhi, Yan Zhenqing, Xiao Daocheng, etc., with a long history and is one of the important birthplaces of Chinese civilization.

Later legends have it that a major gold mine was discovered in Linyi, but it has not been excavated, probably buried relatively deeply. In the current late Han Dynasty, it is estimated that it is even more impossible to dig up.

Langxie country is rich in mineral resources, there are 84 kinds of minerals, dolomite reserves rank first in China, diamond, gypsum, quartz sandstone reserves rank second. Lanling iron ore has a recoverable area of 10.61 square kilometers and a total reserve of 1.8 billion tons. The lithology of the ore in this area is magnetite quartzite, the ore quality is good, the mineral particles in the ore are large, and it is an easy ore to be selected.

Gongsun Kang has already designated the Lang Evil Country as another iron ore mining base for himself.

Gongsun Kang still remembers that he had seen one in later generations: a map of the distribution of mineral resources in Shandong. According to the identification on the map, there is a coal mine in the Linyi area. If it can be found, then the coal used for ironmaking will no longer need to be transported to the ocean, and it can be solved on the spot. Build a steel mill directly in the country of Langxi.
