Zheng Peng, as the presiding officer, was demoted and fined, and even lost the title that he had won so hard, and many people scolded Zheng Peng for betraying the interests of the Tang Dynasty for his own personal gain, but it did not affect the process of exchanging prisoners between the two sides.

Although Li Longji said that Zheng Peng was demoted and exiled, Zheng Peng was the one who presided over the prisoner exchange, and the cement formula also had to be handled by him.

Zheng Peng did things vigorously and resolutely, and after receiving the will of the imperial court, outsiders saw that Zheng Peng was very depressed, but he still negotiated with the Tibetan side as soon as possible and exchanged a batch of prisoners back before the Chinese New Year.

The first batch is mainly wounded soldiers and old and young, there are no Zheng Peng's subordinates, and there are also Guo Ziyi and Lu Jin, in fact, you can guess that Carlo and Kuro must be the last important person for Zheng Peng.

Along with the first batch of captives, there were also ten Tibetan craftsmen, whose task was to learn how to make cement, and Zheng Peng had to teach them to make qualified cement independently so that they could make the final exchange.

In order to let Guo Ziyi come back as soon as possible, Zheng Peng pushed away all entertainment during the New Year, and spent it in the workshop to train those Tubo craftsmen, in his own words, they were all mixed like this, there was nothing to celebrate, even Lan Duo personally invited him to Tuqishi to celebrate the Tang New Year and refused without hesitation.

The production of cement is very simple, but the Tubo craftsmen are obviously not as studious as the Tang craftsmen, and the foundation is poor, Zheng Peng almost taught them from scratch, and after teaching, they had to let them try to make cement, and finally learned it, and the Tubo side sent a special envoy to test the toughness of the cement, and was busy for more than three months, and finally in the following year, it was also the ninth day of the third month of the eighth year of the Kaiyuan Dynasty in the border between Pangong and Tubo, exchanging the last batch of prisoners, and when the exchange occurred, The ten Tibetan craftsmen who had learned how to make cement returned to Tibet with the last of the Tibetan captives.

"Zheng Qian's cavalry envoy has all been verified, and there is no problem with personnel and goods." A battalion in charge of logistics was reporting to Zheng Peng.

Before each prisoner exchange, both sides will send someone to verify the identity and confirm that there is no problem before exchanging, these are the procedures that must be followed.

Different from the previous batches, the last batch included the gold and livestock that Tubo compensated Datang, in addition to the prisoners on the list to verify their identities one by one, they also had to check the fineness of the gold and the health of the livestock, and the person in charge of the acceptance of Datang spent a lot of effort.

Zheng Peng put down the binoculars in his hand, handed it to the cardinal dressed as a man on the side, nodded and said, "Very good." ”

After speaking, he drove the horse forward, and the cardinal on the side saw it and hurriedly followed, as if there was a tacit understanding, Zheng Peng just drove forward, and Kuro and Carlo on the opposite side also drove forward, and the two sides stopped when they were about two zhang apart.

"Zheng Jianjun, don't come unharmed, right?" Kuro arched his hand to Zheng Peng and said with a smile.

The smile is not fake, but it is not aimed at Zheng Peng.

The thought of completing the mission and being able to go to the city of Luo to receive the reward of Tubo Zampu made Kuro feel a visceral excitement.

Embarking on a path of no return, for Kuro, the focus now is on the welfare of the Qarluqs.

Zheng Peng said with a wry smile: "Let the young patriarch disappoint, I am now deposed and no longer serve as the deputy supervisor of the Western Regions, just call me Zheng Qian's cavalry envoy." ”

Carlo, who was standing next to Kuro, smiled: "We recognize the person Zheng Qianqi, not the name, even if it is Zheng Qianqi, he deserves our respect." ”

Speaking of this, Carlo lowered his voice and said: "This time the prisoner exchange can be smooth, Zheng Qiancai's contribution is great, after the exchange, we have a generous gift, as a show of our little compensation to Zheng Qiancai." ”

"This is better excused, this matter has already aroused criticism from the government and the opposition, and if you accept a big gift, you will be guilty of this crime." Zheng Peng hurriedly waved his hand and refused.

At this time, Kuro stood up at the right time and persuaded: "Zheng Qianqi, this is Ka Lao's intention, there is absolutely no other meaning, it has been arranged, and no one knows about it, so you can accept it with confidence." ”

Zheng Peng didn't want to entangle with them on this issue anymore, so he said directly: "Okay, since the identity has been verified, let's start exchanging." ”

"Okay, swap!" Carlo waited for the return of the Tibetan craftsmen who had learned cement like the stars and the moon, and immediately agreed.

Both sides returned to their respective teams, and soon, the last of the captives began to be exchanged.

Guo Ziyi stood at the front of the team expressionlessly, his face did not have the joy of the afterlife, on the contrary, others looked a little gloomy, he looked at the oncoming Tubo captives, and a trace of fierceness flashed in his eyes: it was these Tubo people who made so many of their brothers a burden, and their own reputation was damaged.

If it weren't for the comrades-in-arms around him, Guo Ziyi would really want to rush up and fight with them.

Looking up, seeing a familiar figure from a distance, Guo Ziyi's heart was cloudy, and a look of relief flashed in her eyes, but she quickly lowered her head in shame.

There is no impermeable wall in the world, when Guo Ziyi was still imprisoned, Kuro asked him to drink once, the process was similar to Zheng Peng, after the brotherhood was severed, persuaded Guo Ziyi to be used by Tubo, and talked about Zheng Peng's affairs during the banquet, saying that the Tang Dynasty was unkind to the meritorious soldiers, and refused to save those who were unfortunately captured for the country, and Zheng Peng buried the title and future in exchange for Guo Ziyi and others.

Guo Ziyi has read countless people, and can see that Kuro is not lying, and his heart is full of guilt towards Zheng Peng.

If it weren't for himself, Zheng Peng wouldn't even have a title, and he would have to be exiled to Da Bolu, Guo Ziyi believes that with Zheng Peng's character, if it weren't for saving himself, Zheng Peng, who has always been low-key, would never do such a thankless job, and put his future on the line.

In fact, not only to catch the future, but to fight for his life, in exchange for someone else, he would have been executed for treason, and it may also affect his family, that is, Zheng Peng is so favored, the emperor is still angry, if it weren't for Zheng Peng's usual popularity, someone said good things for him at critical moments, maybe he would be sentenced to Chang'an prison now.

This brother really didn't staggered himself.

Guo Ziyi walked fast and urgently, just walked through the buffer zone agreed by the two sides, and immediately rushed out of a team of Datang's sword and shield soldiers, without saying a word, he blocked behind Guo Ziyi and others, and used a shield taller than a person to face the direction of Tubo, and retreated backwards, covering the retreat of his comrades who were released by Tubo, lest the Tubo people put cold arrows in their backs.

Seeing Guo Ziyi's safe return, he had been waiting for Zheng Peng to meet him immediately, hugged him, and said happily: "Great, great, big brother, you are finally back." ”

In the face of Zheng Peng's warm embrace, Guo Ziyi's movements were a little stiff, and she gently hugged Zheng Peng in the middle of the ring, and said with some guilt: "Third brother, it's the eldest brother who has affected you." ”

If it weren't for himself, Zheng Peng would definitely not have volunteered to grab the drudgery of the negotiation, let alone agree to hand over the crucial cement formula to the sworn enemy Tubo, if he hadn't handed over the cement formula to Tubo, the title and future would not have been discarded, as soon as he thought of this, Guo Ziyi had an idea of why he didn't die on the battlefield.

Zheng Peng said with a nonchalant face: "Big brother, don't say that, if it weren't for your many times to save you, I would have died in the chaos a long time ago, if it weren't for protecting me, how could those Tubo people trap you, it should be the younger brother who dragged you down, that is, there is guilt, and I feel guilty, it is I who have damaged my reputation by causing my eldest brother." ”

Protecting the retreat of the generals was originally the responsibility of the soldiers, Guo Ziyi knew that Zheng Peng was afraid that he would feel bad about himself so he said this, and he was secretly moved in his heart, but he quickly said with a displeased face: "Third brother, I know that you can come back safely this time because you have made a lot of effort behind your back, in fact, you don't have to be like this, isn't it just a life, give it to him, eighteen years later, a certain man is a good man, you don't need to exchange your title and future, it's too worthless." ”

"If you don't have a life, what's the use of all these fame and fortune" Zheng Peng said with a straight face: "Big brother, since you are brothers, you don't need to say anything, just the so-called stay in the green mountains, don't be afraid of no firewood." ”

Guo Ziyi's eyes lit up, and she said with a straight face: "That's right, stay in the green mountains, and I'm not afraid of no firewood." ”

Letting go of Guo Ziyi, Lu Jin hugged Zheng Peng all of a sudden, and said excitedly: "Boss, I really didn't expect to come back alive, I want you to die." ”

Zheng Peng gave Lu Jin a powerful hug: "I said, how many people come, how many people return, no matter when you will not stay, this is a promise and a guarantee." ”

Speaking of this, Zheng Peng said with some frustration: "It's a pity that I'm useless, many brothers went back lying in coffins." ”

Pangong made a mistake, and the Yulin army under his command was broken by seven or eight out of ten, with heavy casualties.

Lu Jin immediately said: "After eating the bowl of rice as a soldier, one by one has long put life and death aside, the brothers will not resent the boss, and the boss will pay for the brothers to return to their hometown for burial, so that their souls can return to their hometown, and they will also vigorously support the injured brothers, in order to save us, even the title and future are not wanted, which brother does not give a firm thumbs up to the boss, I believe that those brothers who died in the war know the spring, and they will not blame the boss." ”

"Boss, you have done an impeccable job, and the brothers are grateful."

"That is, following the boss is a blessing that we have cultivated for several lifetimes."

"In the future, the boss will call a certain to the east, never to the west."

"I've followed the boss in this life."

"If Zheng Qian's envoy doesn't dislike it, we also want to follow Zheng Qian's cavalry."

Several brothers of the Tiger Battalion who were exchanged also echoed loudly, and even a few soldiers under Li Xiancheng's command who escaped death also expressed their intention to follow Zheng Peng on the spot.

At this time, Huang Yang, the head of the Western Regions, came over: "Zheng Qiancai, let's go back if you have something to say, this is a place of right and wrong, and I don't know if the Tibetan thieves have a conspiracy." ”

Zheng Peng nodded and said loudly: "The brothers have been wronged, don't say anything, Manager Huang and I set up a banquet in the camp, first drink and don't get drunk and don't return, okay?" ”

"Good!" Everyone responded in unison.
