"The name of Weizhou (now Dingxi District, Gansu) began in the first year of the Jianming Dynasty of the Northern Wei Dynasty (560), and it was named after Weishui. , the seat of governance is in Xiangwu (now southeast of Longxi, Gansu). It has 4 counties of Xiangwu, Longxi, Weiyuan and Yanxian, and has changed repeatedly.

After the 'Anshi Rebellion', the Tubo power gradually strengthened and took the opportunity to invade Longyou. In the second year of Suzong's reign (761), Tubo captured Minzhou; From the first year of Dai Zongbao to the second year (762-763), Linzhou and Weizhou fell into Tibet one after another.

In the next hundred years, Weizhou has been occupied by Tubo, until the fifth year of Dazhong (851 AD), the former Tubo Zan Prangda died, Tubo was divided in the country, and the Tubo chieftain Shang Ting's heart rate river and Wei Erzhou were attached to my Tang Dynasty, and it was this Weizhou that was recovered. ”

Zhang Chengye sat next to Li Bao, pointed to the map of Weizhou and continued: "Now we control Xiangwu County and Longxi County, the other two counties are still in the hands of Tubo, and now Weizhou City is dilapidated. ”

Zhang Chengye complained to Li Bao, which was also understandable, after all, he was just a mortal, and the natural conditions were bad, so he had nothing to do, so he had to take his time.

Li Bao also witnessed the ruins of Weizhou City when he entered the city, the city walls are low, and the ruins can be seen everywhere, you can imagine how difficult Weizhou is as the border of the Tang Dynasty.

In the past, every autumn the Tibetan tribes would come to our Weizhou to attack and harass, because we settled in Weizhou last year, and we were prepared, so there were not many casualties last year.

However, Hezhou (now Linxia, Gansu) and other places that are also border states are quite suffering, but we can only defend Weizhou with limited troops now. ”

Li Bao looked at the map of Weizhou on the wall, and agreed with the hard work of Zhang Chengye and Zhang Qingping. So he patted Zhang Chengye on the shoulder and said, "It's been a year of hard work, Jiyuan, you!" ”

Zhang Chengye saw that Li Bao spoke sincerely, and his heart was also quite moved, "The king has the grace of knowing something, how can he be at ease if he doesn't do it in his heart." ”

After Li Bao entered the city, he went directly to the Weizhou Prefecture to inspect the work without resting, and Zhang Chengye acted as a tour guide and landlord, taking Li Bao to familiarize himself with the situation in Weizhou.

Nowadays, Weizhou is in ruins, and all facilities are very incomplete, especially the population, and there are only a few thousand families in the entire state city, and there are only more than 40,000 people in Dingkou.

There are more than 2,000 people in the Weizhou New Army, and if they rely on the Weizhou tax to support them, the Weizhou New Army can only drink the northwest wind. If it weren't for Li Bao's early investment of more than 300,000 yuan, Weizhou doesn't know what it would have become.

The investment of more than 300,000 guan was also immediate, and the number of workshops and merchants in Weizhou City increased sharply, especially the merchant groups and workshops of the Kang, Qin, Liu, and Wang families, and the scale of them all increased.

However, Weizhou has two major water areas of Weishui and Taoshui, and is located in the upper reaches of the Yellow River, with abundant water resources, and it is very convenient to develop agriculture and animal husbandry.

Moreover, Weizhou is also an important town on the Silk Road, with traffic on all sides, and later generations have known as the throat of Gansu. Weizhou is only more than 200 miles away from Lanzhou, so it is also known as the gateway of Lanzhou.

Such superior geographical conditions are also the reason why Li Bao chose this place as a base, and if he wants to dominate the Silk Road, he must have a logistics and supply base.

Chang'an is the capital of the Tang Dynasty, and although it can gather resources from all over the world, it is not a place where Li Bao can call the shots. Now that he has arrived in Weizhou, Li Bao has no scruples, he can let go of his hands and feet.

Since Weizhou is to be used as his base, he must build Weizhou into a fortress, since Weizhou is short of manpower at this time, but it is necessary to quickly build Weizhou City, Li Bao, as a traverser, still has some shortcuts.

So Li Bao said to Zhang Chengye: "We are currently very urgent to build the city, and now it is almost July, and there are still two months before the autumn attack of the Tubo people, so we must build the city of Weizhou before the Tubo people come." ”

Zhang Chengye's face was embarrassed, and he hesitated: "I'm afraid it's a little difficult, the king. But I will do my best. ”

Li Bao laughed, don't worry, I have a good product here, as long as we make this good product, it will be okay to build a city.

Zhang Chengye listened to Li Bao's words, his face immediately became lively, he had always known that Li Bao had a magic method and understood thaumaturgy, so he was very curious about what Li Bao said about the good product of building the city, so he said: "Don't sell the king, what is this good product for building the city?" ”

Li Bao smiled: "This thing is called cement, it is made of limestone and clay in a ratio of three to one mixed and burned and ground to make mud. It is stronger and more durable than any kind of fortification slurry in ancient and modern times. ”

When Zhang Chengye heard this, he was so happy that his face was almost blind. He hurriedly found a piece of paper and wrote down the method Li Bao said, and then said eagerly: "Is the cement that the king said really so wonderful?" We need to transport sand, gravel, mud and so on to build the city, even if the cement is strong, but there is not enough manpower, and the progress of chiseling stones is not fast. ”

Li Bao laughed, "You don't have to worry about this, our cement also has an advantage, as long as you put the gravel in it and wait for it to solidify, it is tighter than the stone." ”
