According to the news provided by Hu Yange, Zhou Bo knew all the calculations of the Xiongnu, and it turned out that Mao Dun Shan Yu made two preparations, while arranging Hu Yan Ge to create an incident in Hexi to attract the attention of the Qin army, and Mao Dun Shan Yu himself personally led 30,000 soldiers in the land of Hexi to wait for the opportunity to attack and kill the prince and brother of the Yue clan, as long as those princes and disciples who went to study in Daqin in Hexi had an accident, then Daqin naturally became the first target, and then those princes whose heirs had died in Hexi would inevitably resent Daqin, Hu Wei Sejia, the king of the Yue clan, went to war with Great Qin.

Zhou Bo looked at Hu Yange and said with a smile: "The calculation is really good, but it's a pity that you, the mastermind, are too cowardly." ”

Seeing that Zhou Bo was laughing at himself, Hu Yange was not annoyed, and even licked his face to show favor to Zhou Bo.

After the Tiger Ben Army guards left with Hu Yange, a lieutenant beside Zhou Bo said his thoughts: "General, such a cowardly person, he dares to sneak into my Great Qin to make trouble, it's really hateful, why don't you kill it?"

Zhou Bo shook his head with a smile, and said earnestly: "So cowardly, why kill it, not only should we not kill this person, but also return this person to the Huns intact, and to create momentum for this person, just say how this person would rather die than give in, in short, we want to say that this person is a hero of the Huns." ”

"Why is that?" The lieutenant asked, puzzled.

"Such a cowardly person, if he dies, how boring it is, if this person is portrayed as a hero of the Huns and returned to the Huns, wouldn't it be beautiful for him to continue to plague Mao Dunshan."

After Zhou Bo's explanation, the captain understood Zhou Bo's intentions, smiled and stopped talking.

"You go and pass on my military order, and the army will immediately set up camp and set up camp, and there is one more thing, Huyange confesses, remember not to make it quiet."

Captain "No" quickly left after receiving the order.

Although the crisis in the city of Ganzhou has been resolved, but the entire land west of the river is still in the haze, the missing mission has a whereabouts, the most deadly thing is that at this moment Mao Dun Shan Yu is wandering in this place west of the river, ready to wait for the opportunity to attack and kill the prince and brother of the Yue clan, if Mao Dun Shan Yu succeeds, then Zhou Bo will be finished, just the offensive words of the ministers, enough for him to drink a pot.

Taking advantage of the opportunity for the army to pull out the camp and raise the village, Zhou Bo wrote a letter to Xianyang, and Zhou Bo reported the situation in Hexi to Fusu in detail in his heart; The disappearance of the mission, the rebellion of Huyange, and the activities of 30,000 troops led by Mao Dunshan Yuqin in Hexi.

After writing the letter to Fusu, the army was almost ready. Due to the urgency of time, Zhou Bo did not have time to personally report the details to Shusun Tong, so he had to arrange for a messenger to report to Shusun Tong.

After leading the army to leave Ganzhou City, Zhou Bo arranged for the army to search and advance in the direction of Yueshi in two ways, thanks to the exchange of scouts between the two armies, so the two armies always maintained a distance of about 100 miles during the march.

In fact, Zhou Bo also has a secret weapon, that is, Fusu handed over the first batch of flying slaves (pigeons) trained by the Daqin Military Academy to transmit information, as a general trained by the Daqin Military Academy, Zhou Bo naturally knew the importance of this flying slave, but because of the gold of the flying slave, he did not use it easily.

In addition to Fei Nu, Zhou Bo also brought a person with him in this operation, that is, Hu Yange, but the treatment of Hu Yan Ge is much worse than that of Fei Nu, in order to dispel Mao Dun Shan Yu's concerns, Zhou Bo locked Hu Yan Ge in the prison car, in order to create Hu Yan Ge's unyielding heroic characteristics, Zhou Bo also specially arranged for the soldiers to beat Hu Yan Ge fat, Hu Yan Ge beat his nose and eyes were swollen, miserable.

Scattering 20,000 troops in the huge land west of the river is really insignificant, for several days, two tiger army, hundreds of big tiger army detective cavalry, never found any trace of Mao Dun Shan Yu.

On this day, when Zhou Bo and his entourage were cruising two hundred miles from the border between Daqin and Yueshi, a flying slave landed in front of a tiger lieutenant, and this flying slave had a letter tied to his leg.

The lieutenant didn't dare to slack off, and sent the exhausted flying slave to Zhou Bo along with the letter.

Releasing the flying slave, it can be seen that the Qin army who sent this letter encountered an emergency, otherwise he would never have used the flying slave easily. Due to the bitter cold of the winter in Hexi, this flying slave was exhausted when he flew to Zhou Bo and the others, and when he saw Zhou Bo and others wearing the uniform of the Great Qin Tiger Army, he fell headlong in front of the Tiger Army.

Zhou Bo untied the letter tied to the flying slave's legs, and then handed the flying slave to the guards beside him.

"The Xiongnu army appeared in the northwest of Suzhou County, less than 50 miles away from the prince of the Yue clan, please rush to the aid of the two armies, and at the beginning of the 20th."

After reading this sentence on the letter, Zhou Bo asked the guards to take out the map of Hexi, Zhou Bo looked at the map carefully, and after a few breaths, he found the place referred to in the letter on the map, Zhou Bo took out a charcoal pen and marked it on the map, and then took out a ruler and measured it in detail on the map.

After a while, Zhou Bo put away the map in his hand, and then began to issue military orders to the generals around him: "Everyone, the Xiongnu army is sixty miles ahead, according to the news of this letter, it is inferred that the Xiongnu are likely to have found the traces of the prince and brother of the Yue clan, and the situation is critical, I must meet the prince and brother of the Yue clan before the Huns, otherwise something will happen." ”

Before leaving, Zhou Bo also sent a messenger to another Huben army to inform him of the news about the Xiongnu.
