Jia Xu has a plan, but he doesn't know how to observe the weather, Qin Feng said that there is rain today, and it is really raining, which makes him very surprised, a military general who is famous for his military force actually knows how to see the sky, which makes him have to distinguish Qin Feng from other generals.

He pondered for a moment and asked, "Do you know how long this rain will last?" ”

Qin Feng turned his head and looked at Jia Xu, turned around and continued to look at the heavy rain outside and said, "I don't know how long this rain will last, but there will be rain in the next three or four days, it will rain in the middle, stop!" ”

Jia Xu touched his long beard, looked at the rain curtain outside, and arched his hand and said, "In this case, why don't you send a general to lead a detachment of 3,000 men and horses to attack Tongguan?" ”

Qin Feng was stunned for a moment, a surprise attack on Tongguan? The idea was just like a fantasy, but it was like a meteor across the sky.

Yes, Tongguan is the gateway to Guanzhong, if you want to keep the fruits of this victory, you still have to fight Tongguan in the end, the ownership of Tongguan is related to who has the initiative on the battlefield, as long as Tongguan is taken, no matter how long Chang'an fights this battle, he can be calm, and if Tongguan is not taken, once Cao Cao receives the news, it is impossible not to send troops to help, unless he can sit back and watch Chang'an fall!

Thinking of this, Qin Feng immediately said to a personal soldier next to him: "Go and call Lu Meng!" ”

"No!" The pro-soldier battalion ran into the rain with a bang.

It didn't take long for Lu Meng to run after his own soldiers, and both of them were drenched.

"I've seen the lord!" Lu Meng entered the big tent and saluted Qin Feng.

Qin Feng raised his hand and asked, "Ziming, I have a great military merit that I want to give to you today, it depends on whether you dare to take it!" ”

Lu Meng's spirit was shocked, and he hugged his fists and said: "Please give an order, and your subordinates will never give up!" ”

Qin Feng got up, took the horsewhip and walked to the edge of the sand table in the middle to greet Lu Meng: "Come here!" ”

Lu Meng stepped forward in accordance with his words, and he looked at the sand table in front of him in surprise, "This is?" ”

"Sandbox! Imitation of the actual terrain with a miniature version of the geographical model made of sand, you see, this is Guanzhong, the southeast is the direction we came from, here is Wuguan, the south is Hanzhong, this is Chang'an, our army is now in this position in the southeast of Chang'an! ”

Lu Meng was amazed.

Qin Feng swept all the way over the city south of Weishui on the sand table with his horsewhip, and finally landed on a pass and asked, "Where is this?" ”

Not to mention that the model pass on the sand table has been marked, but it is not marked, Lu Meng also knows what this pass is, and said: "Tongguan! ”

"Not bad!" Qin Feng nodded, "Before fighting Chang'an, I want to take Tongguan first, in this way, it will be equivalent to cutting off the connection between Chang'an and Xudu, even if Cao Cao sends a large army to come, it will be blocked by our army to the east of Tongguan!" ”

"I want you to take three thousand elites to attack Tongguan, it has been raining for the past few days, you can take the army to Tongguan under the cover of heavy rain, but remember, don't be brutal, you have to use your brains!"

"In addition, the time for our army to go out of Wuguan is only three or five days, and the people in Chang'an City only know that our army has sent troops in the last one or two days, and the defenders of Tongguan must not know the news, plus there is rain in the past few days, the news should continue to be delayed for a few days before the defenders over there in Tongguan can be known, this is also your chance, if you want to take Tongguan, you must be unprepared to attack it!"

"Marching in rainy days is a severe test for the soldiers, you and the soldiers will take the task of this surprise attack on Tongguan as a long-distance rapid march, you must remember that if it suddenly rains on the way to the march, you must not let the soldiers advance in the rain for a long time, you must take the soldiers to find a place to shelter from the rain within an hour, and wait for the rain to stop before marching!"

"You go and prepare, wait for the rain to stop and pick up three thousand men and horses, each of them bring five days' worth of dry food, take off the armor before leaving, and travel lightly should be able to speed up the march, there are three hundred sets of clothes on the baggage side, you take them all!"

Lu Meng clenched his fists and agreed: "Subordinates obey orders!" ”

The rain fell for nearly four hours before it stopped, the rain was too heavy, and it was long, and many places became a piece of Zeguo, in this case, it was not possible to send troops to attack Chang'an, and it was necessary to wait for the weather to dry up.

Watching Lu Meng quickly disappear on the horizon with three thousand men and horses, leaving only the mud all the way.

Qin Feng asked Jia Xu: "Wenhe, do you say that Lu Ziming can take Tongguan?" ”

"It's up to man!" Jia Xu smiled.

This old fox! Qin Feng sneered in his heart.

For the next few days, the rain stopped, stopped and stopped, and the roads could not be dried up.

Tongguan.

It was raining in the sky, and the castle was empty, and the defending sergeants on duty had taken refuge in the towers to avoid the rain.

Under the city tower, in the cave of the city gate, a dozen sergeants leaned against the wall with spears and chatted and farted, very bored.

In the rain, a caravan drove a vehicle full of goods to the outside of the city gate, the defending sergeants saw that one by one came to the spirit, this is the time to fish for oil and water, in the past, as long as there was a caravan passing by, the sergeants on duty each would make a sum of oil and water, the officers were more shared, and the sergeants were less.

"Stop, what?" The little colonel of the city gate stepped forward and asked with his hand on the hilt of his sword.

"I'm waiting for the caravan of the Chang'an Huangfu family, why don't we get out of the way!" The leading caravan steward stepped forward and said with a proud face.

This steward's face and arrogance made the city gate school a little uncertain, after all, he was just a city gate school, looking at the other party's momentum, he really didn't dare to be presumptuous.

This allowed him to let him go like this, and he was unwilling, and immediately said: "There is an order from above, and passing pedestrians and vehicles must be strictly checked!" ”

"You, come here!" The steward pointed to the Colonel at the City Gate, and then motioned for the Colonel to talk to him.

The little colonel hesitated for a moment and followed the steward to the side.

The steward stopped Xiao Xiao's shoulder, and as he spoke, his other hand suddenly took out a dagger and cut Xiao Xiaoxiao's throat, and when he turned around, he shouted: "Do it!" ”

Hearing the steward's shout, the caravan guards took out a crossbow from the cart and aimed it at the dozen or so defending sergeants at the city gate.

"Whoosh ······"

In just one round, the dozen or so defenders were all shot down, and some were not dead, screaming, and the caravan guards drew their blades and rushed forward to kill them one by one.

"Blow the trumpet, quick! The first team rushed to the city tower to kill all the people above, and the second team followed me to guard the city gate hole under the city tower, hurry up! ”

With the loud shout of the steward, dozens of caravan guards took action one after another, at this time it was no longer possible to sneak around, the screams of these sergeants in front of the temporary just now had already been heard, he was not sure that the guards up and down the city tower and inside the pass had heard it, and he couldn't care too much at the moment.
