Just as Cao Cao was on his way to Pengcheng, Zhang Yan, who was in northern Xinjiang, received Zhang Zai's order and quickly returned to Jinyang to meet Zhang Zai.

Zhang Yan, who rushed back from the dust, didn't rest for a while, and came to the palace to meet Zhang Zai after simply bathing and changing clothes.

Zhang Zai looked at Zhang Yan, through the news of the bad guys, after Zhang Yan heard his order, he rushed back directly without stopping, and there was almost no rest on the way.

Zhang Zai sighed with emotion and said to Zhang Yan: "Feiyan, there is something you need to do when you are transferred back this time. ”

"The King's command." Zhang Yan bowed and bowed.

Zhang Zai helped Zhang Yan up and said, "Feiyan has lived in Taihang Mountain for a long time, is she still familiar with Taihang Mountain?" ”

Zhang Yan didn't understand what Zhang Zai meant, but he faintly had some guesses, and said respectfully: "Back to the king, this Taihang Mountain stretches for thousands of miles, and the minister doesn't dare to say that he is familiar with it, but he also knows the terrain of many places. ”

"Then are you familiar with the terrain around Wei County?" Jang Jae asked.

Zhang Yan was stunned for a moment, and then replied: "The king forgot, the last general often entered Wei County from Taihang Mountain back then. ”

"And where do you remember the terrain now?"

"Of course I do."

"Good!" Zhang Zai slapped the table in front of him vigorously, and then led Zhang Yan to a map, and said, "Lone has an order, I don't know if Feiyan is willing to carry it out?" ”

"I want to serve the Lord." Zhang Yan was already a little sure of Zhang Zai's thoughts.

Sure enough, I only heard Zhang Zai say: "Feiyan, the war in Youzhou is tense now, so I want you to take advantage of Yuan Shao and the others' attention to Youzhou, and take the opportunity to send troops to harass the rear of the Jin Kingdom." ”

"The last general commands." Zhang Yan agreed without thinking about it, he was already familiar with the attack on the rear of the Jin Kingdom, and he was also willing to do so, so Zhang Yan did not have any resistance to Zhang Zai's order.

"Hmm." Zhang Zai nodded, and then said: "But now the domestic troops are a little nervous, so you only have a maximum of 20,000 people on this trip, so your goal this time is to harass you, and once you pass through the mountains and forests and enter the Jin Kingdom, you have to consider the food and accommodation of these 20,000 people." ”

Zhang Yan nodded, indicating that he knew that when he encountered a large number of enemies, it was a big deal to lead the army to escape into the mountains and forests, and he had not done such a thing before.

In the past few years, although he has not entered Taihang Mountain again, he still has some memory of the basic situation in the mountain, and he also knows where there are a large number of wild fruits that can satisfy hunger, and he is the most unlucky, in their previous camp, but there are a large number of fruit trees, this season, it should also be edible, and it can be used as food temporarily.

"Please rest assured, the last general has lived in the Taihang Mountains for nearly ten years, and has also dealt with Yuan Shao's army for ten years, so the last general will save how to deal with it." Zhang Yan is full of confidence in herself.

In the past ten years, he has fought with Yuan Shao countless times, although there is no clear victory, but Yuan Shao is helpless, so he is also full of confidence in this dispatch.

"In that case, then Feiyan prepared quickly, but Lone still has a strategy for you, and this time you will fight, you will follow this strategy."

It's not that Zhang Zai doesn't trust Zhang Yan, but that the guerrilla warfare methods of later generations are mature, and if he can understand it, it will definitely be a great improvement for the current Zhang Yan.

Even if Zhang Yan was puzzled in his heart, he would not question Zhang Zai's words, so he quietly waited for his next words.

"This method of warfare is called guerrilla warfare."

As soon as Zhang Yan heard the name, she became interested, and then quietly listened to Zhang Zai's explanation.

"The main points of the tactics are to rationally choose the place of operation, quickly deploy troops, rationally distribute troops, rationally choose the timing of operations, and quickly retreat after the battle."

"The main purpose of this tactic is to avoid the real and attack the false, and to attack the east and the west, and most of them are based on attacks and disturbances."

Zhang Yan nodded after hearing this, and admired Zhang Zai in his heart, this is simply a tactic tailored for him, he has lived in Taihang Mountain for a long time, and has attacked Yuan Shao's rear many times, but every time he always has the advantage in the early stage, the more he ends up, the more he doesn't know how to fight, and Zhang Zai's words today seem to open a door for him.

Zhang Yan immediately knelt down and said, "Thank you for the king's grace!" ”

Zhang Zai accepted Zhang Yan's salute, then helped him up, and added: "With this tactic, I often remember sixteen words at that time. ”

"The enemy advances and I retreat, the enemy is stationed and I disturb, the enemy is tired and I fight, and the enemy retreats and I chase."

After hearing this, Zhang Yan secretly pondered for a while, only felt that the more he listened to these sixteen words, the more reasonable they became, almost a summary of the previous tactics, he couldn't help but nodded, and bowed: "The king can create such tactics, and he is really a god and a man." ”

Zhang Zai was secretly ashamed after hearing this, but he didn't show it, waved his hand and said: "Where is this creation, this method of warfare has already been used by predecessors, and Gu just summed them up." ”

"Okay, without further ado, you go to the barracks now to order troops, and after a day's rest, set off immediately." Zhang Zai changed the topic and immediately commanded.

"No!" Zhang Yan bowed, and then said, "The last general will retire." ”

……

Just when Zhang Yan ordered his troops, the battle situation in Youzhou was also undergoing tremendous changes.

Tian Feng, who received Yuan Shao's order, rushed to Zhuo County overnight with an edict, and met Zhang He, the second general of Yan Liang, who was facing Xue Rengui.

At present, the Jin army in Zhuo County has a total of 150,000, while the Tang army has 80,000, nearly double the difference in strength.

Before Tian Feng's arrival, Yan Liang and Zhang He had fought with Xue Rengui several times, and there were casualties among each other, but on the whole, the losses of the Jin army were greater than those of the Tang army.

Xue Rengui did not choose to take the initiative to attack, now, they are in two sides of the enemy, the current battle situation in Youbeiping is unknown, and Yan Rou, who fled, has not shown up, although Luo Cheng has been integrating the forces of Youbeiping, but once the alien race attacks, they are likely to be passive first because of the lack of troops.

Xue Rengui had no intention of taking Zhuojun, his purpose was only to deter the Jin army here, and even he was ready to support Luo Cheng in Youbeiping at any time.

Karasuma, Qiu Liju, Yan Rou, who was defeated and fled, was sitting in Qiu Liju's big tent at this time, enjoying a fat roasted whole sheep.

"I don't know what to think about?" Yan Rou asked while cutting the leg of mutton with a knife while looking at Qiu Liju.

"My friend, now is a good time for grazing, and if we send troops, our losses will be too great." Qiu Liju's face was sad, as if they had missed the season, and their losses would be serious.

Yan Rou stopped his movements and looked at Qiu Liju, and said: "Shan Yu, the Ming people don't say dark words, if Shan Yu agrees to send troops, after the matter is completed, the king of my family promises to send a thousand stones of grain and grass, which can be regarded as compensation." ”

"This ......" Qiu Liju was also embarrassed, and he didn't speak for a long time.

"Two thousand stones, no more." Yan Rou looked at Qiu Liju, although he was quite famous among the alien races, he was not enough to let the aliens obey him.

"Shan Yu, have you ever heard of Tang Guo's methods of alien races?"
