Wei Zhen couldn't help but become serious when he heard what Cao Zhang said, and asked: "Third Prince, you said that there is a lot of this fuel in Pingyang, how much is that?" Nowadays, most of the fires are logged, which not only consumes manpower but also has to be dried after cutting to be used, which is very troublesome. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

Wei Zhen Cao Zhang really can't answer this question, but in the era he lived in before, Taiyuan City, the provincial capital of Shanxi, would be stained with a lot of coal ash on the street when it was windy.

So Cao Zhang smiled: "Naturally, there are countless people, Gong Zhen does not let go of it to take a look, remember, do not make a noise after discovering, and after opening the mine, you must also choose to mine graphite in the name, otherwise there are similar examples in other places, and we will lose the advantage of strange goods when mining coal mines, remember, do not sell them after mining, they must hoard a lot, and then make a move." ”

Wei Zhen said: "No! Then he asked, "Please forgive my subordinates for talking too much, where did the third prince get this fuel?" ”

It's no wonder that Wei Zhen is curious, where did Cao Zhang, who is young enough to change the living conditions of the world, know about this kind of thing, which is really puzzling.

Cao Zhang smiled and said, "I learned about it from ancient books. The "Classic of Mountains and Seas" says: "Three hundred miles to the southwest, it is said that the mountain of the female bed has a lot of red copper in its yang, and it has many stones in its yin." This stone is actually the fuel I am talking about. "There is a course in university history called history and technology, Cao Zhang happened to take it, and the professor mentioned that the stone Nirvana mentioned in the Classic of Mountains and Seas is actually coal, as for how to verify it, Cao Zhang forgot it, but he just remembered this sentence, so he used it to prevaricate Wei Zhen.

Hearing this, Wei Zhen said convincingly: "The third prince is really well-read! In the future, if the Huo family expells Shi Ni, he will definitely give the seventh layer of income to the third prince. ”

Cao Zheng nodded secretly, Wei Zhen really knew about it, so he said: "Hengzhu in Beiqu, we also have to wait for the news of Bian Jing's surrender to Li Wenhou, why don't you go to investigate and investigate in person to see if it is as I said?" ”

Wei Zhen said: "The last general has this intention! After saying that, he immediately took his leave.

In the following days, Cao Zhang asked the people to go to the manor of the squire in Beiqu to collect all the ripe crops, part of which was used to fill the baggage in the army, and part of it was used to build Huimin Warehouse, so that the people could borrow food to tide over the difficulties, and at the same time distribute farm tools to encourage them to reclaim wasteland.

And at this time, the imperial court has sent county officials to take over Beiqu County, and at the same time sent a Hanoi man named Chang Lin to serve as the Taishou of Pingyang County, this person is Baihuai, and Sima Yi is a fellow countryman, and at the same time Wen County, but he has been poor since he was a child, and Sima Yi is a family of two people, Cao Cao sent this Han Shi to guard Pingyang, but also to Hanoi, Hedong, Pingyang squires a signal, telling them that the family era has become a thing of the past.

Although Chang Lin loves to disagree with Sima Yi, but he has great respect for Cao Zhang, the first thing he did after coming to Pingyang was to write a letter to Cao Zhang, saying that he had just taken office, and there were many affairs, and he was afraid of disturbing Cao Zhang, who was fighting, so he couldn't come to visit, and apologized for this, and at the same time said that he admired Cao Zhang very much, and mentioned in his heart that he liked to chant the sentence "Poor and uncertain riverside bones, still a person in a deep boudoir dream" After reading this letter, Cao Zhang only felt that he thought that he was very clever and wrote well. I can't help but feel a little more image of this Chang Lin.

At the end of the Han Dynasty, it was very difficult for the children of the Han family to study, first, they had no money to buy books, and second, they had no money to buy lamp oil. So this Chang Lin was born during the winter vacation and has this literary level, which is really impressive.

Cao Zhang also replied to Chang Lin, expressing his gratitude for Chang Lin's admiration, and mentioning that he and Chang Lin were both Hanchen, each performing their own duties, and there was no need to come to the meeting.

Not long after Beiqu County Commander took over the county seat, Bian Jing sent a message, saying that Li Wenhou had promised to return to the imperial court, and now the two of them had led their troops from Huxu to go to Guanwai to meet with the army of Xian Lingqiang and Liu Bao, the Zuoxian King of the Southern Xiongnu, and confront Tuoba Liwei, the leader of Tuoba Xianbei.

Cao Zhang, after receiving the letter, immediately convened the department, the whole army left Beiqu, and also went to the outside of the pass, the target is naturally Tuoba Liwei, the alien races outside Pingyang, the strongest is the first Lingqiang, the Southern Xiongnu and Tuoba Xianbei three tribes, now the Southern Xiongnu and Xianlingqiang have been united with Cao Zhang, only Tuoba Xianbei is left, Cao Zhang wants to fight a big war, not only let Tuoba Xianbei be powerless to harass Pingyang, but also let Tuoba Xianbei slump after this station, and knock off the foundation of their establishment of the Northern Wei Dynasty.

Of course, Cao Zhang naturally wouldn't declare this intention, he just said that he didn't want Tuoba Xianbei to harass the people in Pingyang anymore.

There is the Great Wall in Pingyang County, but it was built in the Warring States Period, Cao Zhang's specialty is history, and the history of the Great Wall, the backbone of China, is naturally well memorized, that is one of the important test points, in history, the Great Wall of Pingyang County was first built by Zhao in the Warring States Period, and then after the unification of the Qin Dynasty, the Great Wall of various countries during the Warring States Period was connected together, and then came to the Han Dynasty, Emperor Wu of the Han Dynasty built the Outer Great Wall in the Hetao area, and surrounded the Southern Xiongnu between the Great Wall of the Qin Dynasty and the Great Wall. Now Cao Zhang's pass with the army is called Fanzhi Pass, which belongs to the Great Wall built by Meng Tian of the Qin Dynasty, and now the Han Dynasty is in civil strife, this pass has been abandoned, which makes the Hu people drive straight into Pingyang and wreak havoc in Pingyang.

Looking at the mottled city wall and the broken female wall at the pass, Cao Zhang sighed and said: "In the past, I didn't know the Cheng Dynasty, Wei Qing, Huo Quai's illness was so brave that he drove the Hu people outside the Great Wall, in the past, the Great Wall of the Qin Dynasty was abandoned because it was already a market outside the city, but now it is because of the civil strife in my dynasty, so that the Hu people crossed the outer Great Wall, broke the Xiongguan of the Qin Dynasty, and ravaged the border of our dynasty, which is also embarrassing to think about." ”

Zhao Yun, who was walking aside, said: "There is also a section of the Great Wall in the hometown of the last general, which was built during the reign of Emperor Wu of our dynasty, and now it is also a virtual existence. ”

Cao Zhang smiled: "That's how Zilong's marksmanship was practiced? ”

Zhao Yun replied: "Exactly. ”

Cao Zhang nodded and said: "I hope that after this battle, there will be a lot of prosperity inside and outside the prosperous pass!" After speaking, he continued to lead the army forward and went out of the pass. (To be continued.) (To be continued.) )
