Just after Tian and Yu gathered up their troops and prepared to rest for a while, they sent troops north to the eldest son city. Zhang Yang was already anxiously walking back and forth in the prefect's residence in the eldest son City, and asked the soldiers outside the gate whether there was any news coming back.

Half an hour ago, on the ancient battlefield of Changping, when the cavalry of Tang army began to attack the camp of Zhao army, several torches could be seen running from the North far away from the north gate of the eldest son city. As early as the torches appeared several miles outside the city, Zhao soldiers, who were in charge of guarding on the city tower, had already found the abnormality in the North official road, and he would be killed immediately His Shangguan wakes up. For a moment, all the taxi drivers on the tower wake up and stare nervously at the torches approaching quickly in the north.

The torches stopped two hundred paces outside the gate of the city. People could vaguely see that there were several cavalry soldiers. One of them rode towards the city. He raised the torches and cried out: "the soldiers on duty at the head of the city listen, we are the messengers sent by Jinyang. Under the order of the prime minister, we have emergency armaments to present to Yang Taishou!"

After hearing this, the city guard did not dare to wait. He called to the knight under the city: "there is no reason to speak. Please show me your token!"

The knight didn't say much. He got off his horse and walked quickly to the moat. He bent his bow and took an arrow towards the city tower. On the shaft of the arrow, there was a token. On one side of the token was a wolf's head, and on the other side was a small seal character "wolf", which was the special token of wolf county.

Although the general on duty at the head of the city knew the token, he still didn't dare to open the gate. After thinking about it, he stretched out his head and said to the knight under the city, "it's not the time to open the city. If you are in a hurry to enter the City, please dismount and get close to the city wall. We'll hang your brother up to the city tower with a hanging basket, and then you'll go to the prefect's house to send a message."

On hearing this, the man knew that it was not the time to open the gate, and that there was nothing wrong with the arrangement. He nodded his head and said, "please arrange a horse in the city. I must report the urgent military situation to the governor as soon as possible."

Seeing that the knight under the castle agreed, the general was also secretly relieved and said, "please rest assured, I have prepared some horses under the castle. Someone will escort you directly to the palace!"

Soon, the suspension bridge at the end of the city was slowly put down. The knight gave his horse to his companion. He quickly walked through the suspension bridge, and then quickly climbed up the hanging basket put down by the tower. Pulled by the soldiers at the end of the city, he climbed up the wall.

Then, under the escort of several city guards, he ran to the direction of the prefecture.

In the prefect's mansion, Zhang Yang, who had been tossing and turning all night, didn't fall asleep until after the third shift. Just after the fifth shift, he was suddenly awakened by his own guards. He said that there was an emissary from Jinyang outside the mansion. He reported the military situation to himself. For a moment, an ominous feeling arose from Zhang Yang's heart, which made his sleepiness disappear immediately.

Zhang Yang knew that the military newspaper he sent to Jinyang had only been out for one day, but Jinyang's reply didn't come back so soon. The only possibility was that Jinyang must have found something wrong with the Tang army, and it was only then that the reply was sent overnight.

Thinking of this, Zhang Yang put on his clothes while waiting for the woman, and asked the messenger to come into his study. Soon, Zhang Yang came down to the study under the guard of the guard. As soon as he entered the study, Zhang Yang saw that the messenger's token in the guard's hand turned out to be a silver token. When he looked at the messenger again, it was indeed the leader of a wolf pack he had seen in Jinyang.

The spy organization of Zhao state is wolf group, which is divided into a wolf king with gold token, five wolf generals below the wolf king, each with silver token, copper and iron wolf generals below, and ordinary wooden wolf at the bottom.

The man Zhang Yang saw now was one of the five silver wolf generals. His face was covered with dust and haggard. Seeing Zhang Yang enter the door, he quickly bowed down and said, "silver wolf LV Jiu, please see Zhang Taishou!"

"General Lu doesn't have to be polite. I don't know why the prime minister sent you here?" Zhang Yang quickly lifted him up and asked;

instead of speaking, LV Jiu turned his head and looked at the guards around him. Seeing this, Zhang Yang quickly killed the guards around him, leaving only his own personal commander, that is, his nephew Zhang Ke, and then said, "general Lu, please say that Zhang Ke is not an outsider."

"Please pay attention to the prime minister. It is very likely that the Tang army will attack gaopingguan and Yu's from the ancient Baixing road. Please pay attention to the prime minister." With that, Lu Jiu took out a letter box from his arms. There were three red signs on it. Then the letter box was sealed with red ink.

After listening to Lu Jiu's words, Zhang Yangmeng quickly took the letterbox from his hand. Then he opened the letterbox and said to Zhang Ke: "Zhang Ke, open the map of Shangdang."

Zhang Yang took out the letter from the letterbox and scanned it at a glance. Then he put his finger on the map where he and gaopingguan were. Compared with Chen Gongxin's understanding of the ancient Baixing Road, an ominous feeling rose from the bottom of his heart. He had a premonition that the Tang army might have entered the Shangdang border, and Hao Meng's 6000 troops might have been ambushed by the Tang army.

Thinking of this, Zhang Yang ordered: "Zhang Ke, you immediately send 500 cavalry down the official road to chase general Hao Meng's headquarters. If you catch him, you will order him not to go south to tianjingguan, but to gaopingguan to take over the defense. If..." At this point, he wants to say nothing.Zhang Ke said: "adults mean that they are likely to..."

"Yes, I hope my intuition is wrong. If you don't find them, they will be ambushed by the Tang army. No, you will take the lead. Remember, the five hundred cavalry must be divided into several units, each of which is not less than a mile away. If you find anything unusual, you will return immediately without any hesitation. "

"The end will take orders!" As soon as Zhang Ke heard this, he immediately understood the seriousness of the matter and took orders to turn around and leave.

As soon as Zhang Ke left, Zhang Yang ordered: "come on, pass the order. If there is no hand written by the prefect himself, no one can open the city gate, and collect 5000 prefectures and soldiers in the city. From now on, a thousand soldiers will be set up on each side of the city wall, and any abnormality will be reported immediately."

After thinking about it, Zhang Yang asked Chang Shi to come and ordered him to recruit another 5000 soldiers in the city immediately. Although he was only the lowest level ordinary soldiers, it was OK to help him pass the arrow and move the rolling stone and log at the head of the city.

Later, Zhang Yang ordered to send 1000 soldiers to Huguan county from Lu County, Kaiyuan city, tongkai city and Guyuan City. In this way, there would be 6000 troops in Huguan county. In addition, the terrain of Huguan was very steep. If the eldest son city could not be defended, he was ready to retreat to Huguan city. At least he should stick to the Shangdang until Jinyang army arrived, or even the king's army came back Only in this way can it be possible to keep the upper party, otherwise Zhao will lose this strategic place.
