The great cause of salt production in full swing was carried out in Guzhu City for a few days and nights. In addition to the necessary security and the army of boiling dung, the rest of the people can not go out without going out, for fear that they will not be clean for a few days if they are contaminated with the smell of.

Xu Ao has been plugging his nostrils with something for the past few days and breathing through his mouth. But the strong smell made him have the illusion of eating. Not to mention the few guys who were caught, they all vomited and collapsed on the first day.

After a few days of completion, a total of more than 300 catties of salt were produced, plus some coarse salt in the city, which was also enough for the amount required by Beidi.

In order to cover up the lingering sour smell of salt, Xu Ao specially ordered someone to stuff a few salted fish in each bag of salt, if Beidi asked, it would be the smell of salted fish, anyway, in Xu Ao's nose, these two tastes are similar.

As for the adulteration of salt suggested by some generals, it was vetoed by General Qin and others without Xu Ao thinking about it. First of all, regardless of whether Beidi can see through the poison in the salt, even if they can't see through it, won't they use people to test the poison? In addition, Xu Ao seemed to have seen the figure of the demon clan in the Beidi camp a few days ago. You know, the monsters who have become spirits have a much more intelligent nose than people, and as long as they don't know how to make dung salt, they can still get away with it. If it is poisoned, no one can guarantee that it will not be discovered.

If it is discovered, those thousands of captives are destined to die, not to mention, how many people who go out of the city to exchange prisoners can come back, it depends on the creation.

Therefore, General Qin and others vetoed this plan first.

After another day or two, the men who had gone to the rest of the cities to collect cloth also returned. According to the agreement negotiated with Beidi a few days later, Beidi retreated five miles back from the encirclement at the north gate of Guzhu City, vacating an area specifically for prisoner exchange.

At the end of the Qin and Yan armies, carts were piled with cloth, tea bricks, and salt. Led by Xu Ao and other six young generals, a cart of cars was pushed from the small gate on the side of the north gate to the open space and piled up. Behind him were 3,000 soldiers armed with strong crossbows, pressing the more than 3,000 people captured by Beidi. A few warlocks mixed in the small soldier team had already pinched the trick in advance, and once the situation changed, they would burn the supplies as soon as possible, and burn as many camps as they could burn Beidi.

At the other end of Beidi, the green robe did not come, and although the rising sun appeared on the edge of the camp, it did not come close. Tubo, who Xu Ao had dealt with several times, led three to five hundred people and pressed nearly six thousand prisoners.

When the Tubo saw Xu Ao from afar, he opened his arms and greeted him with a big hug: "The ancestor has spoken, we will stay with those craftsmen, but about a thousand people don't want money to give to you." ”

Before Xu Ao set off, Wang Bai and the others had already expected this situation, after all, the craftsmen of the Qin army were famous all over the world. It is understandable that Beidi, who has low productivity, wants to find a way to keep craftsmen. General Qin also ordered that those craftsmen in the army could be exchanged as much as possible. I really can't change it back, so I will exchange their family members back. After all, these days pay attention to a son inheriting his father's business. Many of the craftsmen who accompanied the army had a son or nephew to work in the army. Those miscellaneous children, Beidi naturally doesn't look down on them. Being able to exchange one for one can be regarded as retaining a little bit of blood and bones for them. As for those craftsmen, when the prisoner exchange is over, send a group of dead soldiers, and never let them be used by Beidi.

Xu Ao waited for Tu Bo to let go of his arm and took out a beautiful wooden box from his arms, which contained three small high-grade tea bricks: "Brother Tu Bo, this is a gift I have prepared privately, and I hope to accept it." ”

Tubo looked at Xu Ao with a smile for a long time, and suddenly asked, "Don't you hate me for cutting the noses of those captives?"

Xu Ao was stunned for a moment, he didn't think about Tubo asking this question at all, hesitated for a moment, and decided to tell the truth: "I'm very angry." Otherwise, I wouldn't have gone down to the city to save people. However, after returning to the city, I listened to General Ma tell me what happened, and I couldn't get angry when I saw the tragic situation of the Beidi men captured by Qin and Yan's two armies being abused. The two sides are at war, and some things are really inevitable. ”

Tubo rubbed the beard on his face: "I didn't expect that kid to be a general, but I thought he was an ordinary soldier." Also, don't call us Beidi, because I don't know what it means to be savages? Although our families are not unified, we also have our own names. My tribe is called the Moon Wolf, and they live near the most famous Moon Lake in the northern grasslands, and strictly speaking, we are the descendants of the Xuanyuan clan. When there is no more war in the future, welcome to come and be a guest. ”

Xu Ao sighed and laughed, "If we all survive." ”

Speaking of this, Tubo's eyes were also dark: "Yes, if we all survive." ”

One is a junior general of the Qin army, and the other is a general of the Northland. But no one wants to continue to fight this senseless war.

Occasional looting is one thing. For the semi-settled tribe of the Moon Wolf Tribe, killing the Qin and Yan people, who are also descendants of the Xuanyuan clan, will always have some mustard in their hearts.

Tubo suddenly took out a small box from his arms: "Here, it is an ointment made by the clan's sacrificial wine." It is still a recipe left over from the Xuanyuan period. It can be regenerated with severed limbs, nose and ears or something, and it can be recovered in three or five months. Hands and feet, it will take a long time, maybe it will take ten years to grow. Apply it once in the morning and once in the evening, and the size of the nail is enough. Even if it's my gift to you. ”

Xu Ao didn't shirk and put the box in his arms.

Next, the two sides officially began to exchange prisoners.

Groups of captives staggered past each other, staring at each other's scars from time to time. Most people's eyes are filled with the joy of the rest of their lives.

The company entered the city with all the captives of Qin and Yan, who had been captured by the Tubo tribe.

Xu Ao and the rest of the people led the strong crossbowmen who went out of the city to exchange prisoners and retreated into the city.

Truckloads of supplies were left in place, waiting for Beidi to send someone to take over.

As soon as one of the warlocks of the Qin army raised his right hand, he was ready to release the spell that had been pinched a long time ago. was pressed down by Xu Ao with one hand.

The warlock dressed in a small soldier costume looked up at Xu Ao who was riding a tall horse in confusion, Xu Ao just shook his head, but did not explain anything.

In the city, under the instructions of General Qin and General Le, a grand welcome ceremony was prepared for the captured soldiers.

The wide roads in the city were now filled with soldiers carrying rice wine and wounded medicine, leaving only a path large enough for three or five people to walk side by side. As soon as the freed brothers entered the city, rice wine was stuffed into their hands. With one greeting after another, food and medicine were stuffed into their arms one by one.

The high-ranking generals of the Qin and Yan armies stood in front of the square in the center of the city to personally greet these returning warriors.

Seeing that they all entered the city safe and sound, the suspension bridge at the north gate also slowly rose behind Xu Ao.

General Qin and the others, looking at these abused warriors, bowed down and bowed together: "Brothers, you have suffered. ”
