Salted fish is fish that has been salted and then dried. Because there is no low-temperature preservation technology, the fish is perishable easily.

When Yang Xi developed Dongting Lake, he suggested that some trading houses start to manufacture large-scale fishing nets and start fishing, and pickle salted fish in large quantities.

Among these merchants, it is the Eastern Airlines Commercial Bank that implements Yang Xi's guidance the most, and now the Eastern Airlines Fishery dominates Dongting, and the salted fish business is laid throughout the Chenhe District.

After the completion of Shanghai City, China Eastern Airlines Fishery began to purchase a large number of fresh fish along the coast and set up a large-scale salted fish factory.

After seeing Lu Dong and Cen Hang, Yang Xi said: "I have another way to make a fortune here, you should be interested." ”

Lu Dong and Cen Hang were very excited, every time Yang Xi had a small idea, it was a earth-shaking change for them.

"I am now 50,000 soldiers, in the upper reaches of Liaoshui, outside the establishment of a big Xianbei city, if you are interested, it is better to join forces with my Chenhe Chamber of Commerce, set up a cured meat factory in Daxianbei, buy a large number of grassland cattle and sheep, pickled beef and mutton, and sell them to the mainland, in this way, it will be a new industry, at the beginning of the investment is not much, only more than 1,000 people of the pickling factory, and so the market opens, it will be a big industry."

Lu Dong and Cen Hang immediately responded, and Yang Xi asked him to start talking with the Chenhe Chamber of Commerce.

If Yang Xi does this, there will definitely be many business houses following suit, and even some foreign forces will join this ranks, such as small tribes of two or three thousand people.

In this way, Daxianbei City has another reason to prosper.

The common development of animal husbandry and planting will turn into the two wings of the eagle and bring the city of Xianbei to the sky.

After staying in Shanghai for a few days, Yang Xi sent an order to Chenhe District, entered the first level of combat readiness, and issued the last battle order of the year.

"Order the Ordnance Industry Department to transport 20 cannons, Jiangdong Theater Huang Zhong led 30,000 men and horses from the headquarters to go north to Guangling County, combined with 30,000 people from the Taishi Ci Department of the Jiujiang Theater, and 3,000 soldiers and horses from the trapped camp and 3,000 artillery battalions, a total of 66,000 men and horses, known as 100,000, to attack Xuzhou in the north."

As soon as this order came out, the world shook, Cao Cao was attacking Gao Gan at this time, and he almost wanted to vomit blood when he received the battle report.

"Vertical Zi'an dares to deceive me!" Cao Cao was furious, and Jia Xu and other strategists did not dare to speak out.

At this time, where did Cao Cao go to find 100,000 people to resist Yang Xi's attack, but he knew that Yang Xi's could produce a bombardment cannon, and the big city of Xiapi was a fortress for others, and for Yang Xi, it was tofu.

Xuzhou defender Zang Ba urgently asked for help, and Cao Cao gathered to discuss.

"Today, Yang Xi led 100,000 soldiers and horses, and 20 cannons to the sky, and he has already shot the sun to the north, and he has killed the next Pi, and the Zang Ba defenders are less than 20,000, dare to ask you, how to deal with it?"

Xun Yu said: "At this time, there is nothing that can be done, Xu Du has only 30,000 soldiers and horses, if it is rescued, Xu Du is empty, if Cai Kao leads the troops to attack Runan, in case Runan can't hold on, Xu Du is in danger and cannot be rescued." Then there is the prime minister's headquarters in Jizhou, the road is far away, Yang Xi and the border of Xiapi, I am afraid that it will reach Xiapi City in a few days, and there is no one to save Xiapi, I am afraid that I can only withdraw the army, and hand over the three counties that were originally agreed to Yang Xi. Otherwise, he captured Xiapi and Chenliu, and then combined with the troops of Qingzhou Weigua and Zhang Liao to attack Xudu, but at that time there were really 100,000 troops pressing the border. ”

Cao Cao's migraine was better again, and he broke out in a cold sweat.

Guo Jia said: "Yang Xichenhe Code mentions the word, the spirit of the contract, I look at this person, the contract is extremely heavy, the lord of the present is a broken contract, I am afraid that it will not be good, if these three counties are conceded, they can also discuss and stabilize, so that they have no excuse to attack Xu Du again, if they do not let it, I am afraid that it is really possible to cause a big war." At this time, I had just taken Jizhou and Youzhou, and my foothold was not stable, so it was not suitable for war. ”

Cao Cao shook his head helplessly.

"Yang Xi this person, the southern expedition to the north, never defeated, this northern expedition Xianbei, but fortunately he defeated Wuhuan, but in the outside of the fortress stumbling, I am afraid that it is extremely unwilling, so annoyed and angry, big moves. It seems that at this time, it can only be given a step, otherwise this person really doesn't know what to do. However, this step is too much, the land of three counties, millions of people, I am not reconciled! ”

Jia Xu said: "Please also ask the lord to make a decision as soon as possible, and if you don't order the withdrawal of troops at this time, I'm afraid that Zang Ba will defend Xiapi, and it will be a heavy loss." ”

Cao Cao saw that no one had any opinions, so he had to write two letters, one to Zang Ba and one to Yang Xi, which were immediately sent out in an expedited manner of 800 miles.

But even if it is sent out at this time, it will be too late.

Two days later, the letter was still halfway through, and Yang Xi had already surrounded Xiapicheng.

Yang Xi shot the letter of persuasion into Xiapi and persuaded Zang Ba to surrender, Zang Ba was furious, scolded Yang Xi for being a rebellious minister and thief, and made it clear that he swore to live and die with Xiapi City.

Yang Xi besieged the city for a day, and as a result, he received two letters from Cao Cao, and Zang Ba's letter was also intercepted by him.

"Haha! Cao Cao, old Cao Tou, play with me to break the contract, and come to play to appease, I don't eat this set, my flaws will be reported, and I don't hide it, provoke me, I want you to take off a layer of skin, and if you take off your skin, you have to kneel on the ground and sing conquest. ”

"Order, today to attack the city, twenty cannons are fired together, we will not enter the city until the city wall is blown to slag, don't care about destroying cultural relics."

Zang Ba stood on the city tower and looked at the dense silver armor in the distance, feeling bad in his heart.

He was imagining, imagining Yang Xi's offensive plan, flashing in his heart one by one, flashing the way to deal with it.

Only the Sky Cannon he couldn't imagine.

Looking at the huge city wall, Yang Xi suddenly felt proud and wanted to write a poem, but he didn't have the talent, so he had to stop with a wry smile, professional people do professional things, don't steal all the good poems yourself, future generations have no ideas.

"Fire!"

A loud noise came out, there was no suspense, and the rammed earth flew wildly.

At this time, the city walls, low-grade, made of rammed earth bricks, high-end, the same, could not withstand a few bombardments.

After four or five rounds, only a lonely city tower remained, Zang Ba was stupid, but there was no way to deal with this.

After fourteen or fifteen rounds, the city wall was gone, the moat had miraculously disappeared, and the rammed earth and the ground had been overturned, filling the moat, and the river overflowed, and I don't know where it flowed.

Zang Ba wanted to surrender this time, but there was no chance, so Yang Xi gave the order.

"Knock down the castle tower, and fulfill his reputation as a loyal martyr."

If Zang Ba knew Yang Xi's thoughts, he would definitely scold him ten thousand times. 、

At this time, Zang Ba wanted to escape from the city, but the city tower was too high and crumbling, only this one piece was left, and even the stairs were gone, he wanted to surrender, he didn't want to be loyal.

So Zang Ba was loyal.

As the first military general to be loyal, Zang Ba had a lot of acceptance speeches to say, but he didn't have a chance.

Yang Xi is not a stingy person, he does not hesitate to spend some more shells to blow up all the participating walls, anyway, it is to be rebuilt, which is regarded as reducing the workload of the engineering team.
