Under the introduction of Sakurai Yuki, Liu Ruohuan gradually discovered the mystery of this layout. He secretly sighed in his heart that General Shao Wu did have the talent of a general.

In this case, as long as he replicates General Shao Wu's formation during this trip, he should be able to restrain the attack of the Huns.

But Sakurai Yuki's next words were like a bolt from the blue.

"But this formation is no longer useful now."

"Ha? This method of setting up a formation is good, why can't it be used?"

"This layout used to be effective all depended on the terrain near these three places. From Cangnan City to Shimen Town, there were steep high slopes between the three terrains. Not to mention horses and mules, it was difficult for even people to climb up... But since the day the capital was attacked, thousands of Hun cavalry appeared behind Hangu Pass without warning. Do you know what this means?"

Liu Ruohuan was confused and understood that the eldest princess had definitely told the Huns a secret passage that was around the pass.

The secret passage can not only bypass three important towns, but also directly attack the capital, leaving the entire Han and Tang dynasties in a passive situation without any dangers.

The eldest princess is really...

Sakurai Yuyu stood up from Liu Ruohuan with her chest covering her chest, "Okay, I have already introduced the battle between the two armies to the young master. I have other things to arrange today. The young master is just alone in the house to think about how to defeat the enemy."

Liu Ruohuan was slightly stunned and asked back, "Sir, aren't I a staff and military advisor around me on this trip? Why did you give me this kind of mental work?"

Sakurai Yuyu, who was wearing a long skirt and a big cloak, turned around and smiled, "Young Master, please remember it. I'm just a little maid in warming the bed. Of course, the young master must do this national affairs by himself."

...

Looking at Zuo Zinan frowning opposite, Liu Ruohuan seemed to see her yesterday.

Zuo Zinan felt this anxious gaze, her pretty face turned slightly red. She resisted the urge to draw her sword and yelled back and said, "Sir, since the military supervisor knows the situation of our army, why is there no worry on her face?"

Liu Ruohuan was helpless. If he wanted to say something worried, he had already been anxious yesterday.

But the border wars today are stubborn diseases accumulated over the years, and it is difficult to distinguish the cause and effect by just their gestures on the map.

So Liu Ruohuan thought about it all night and decided to wait until she arrived at the Zuo family's Yiwei Mansion in the future before saying the rest.

"Report! Urgent!"

A figure rushed in from outside the account. She held the unique expedition military letter from the border and said anxiously: "100,000! The border is urgent! The vanguard of the Xiongnu royal court has reached three important towns in the northern border. In addition, the Jurchen tribe has found traces of the southward journey of the northeast. At present, the opponent's main force is exposed outside Jinyang City. There are many tips to prove that the opponent has formed an alliance with the Xiongnu."

"What!"

Liu Ruohuan and Zuo Zinan exclaimed at the same time, and the pace of the Huns was far faster than everyone's estimates.

Logically speaking, the Huns who had just quelled civil strife should have two or three months of rest for the army.

"This speed is wrong, it's too fast!" Zuo Zinan's face fell down, and her delicate face was full of suspicion. "The logistics supply of hundreds of thousands of troops, where did the Huns find so much food and supplies in a short period of time? Originally, all living supplies on the grassland depended on the trade of border towns. Now the border is banned. Even the gods of the Huns cannot fill the stomachs of so many people!"

Then, she repeatedly confirmed to the soldiers who sent the order: "Are you sure the number of the Hun army is correct?"

"There are all confirmed by several channels. The Huns' vanguard army has a total of more than 100,000 people. They are led by the left and right wise kings. There are 300,000 troops to make the final adjustments and arrive at the border in about three days."

Liu Ruohuan suddenly asked in the middle: "Shouldn't this military situation be examined first? What did the palace man say?"

The female soldier who was sent the order said: "The emperor said that the war in the northern border is all controlled by the military supervisor and the second highman. As long as the Huns have not yet reached the city of Luoyang, it has nothing to do with Your Majesty."

Good guy, this is a decision to be a hand-off manager!

Liu Ruohuan pressed his strong dissatisfaction with the eldest princess and cast an inquiring look at Zuo Zinan, "As soon as the war in the northern border started, a hungry wolf appeared in the northeast. We were really caught... Now this emperor is a ignorant master, Young Master Zuo, our luck is really not good."

"Since the war in the north has begun, I have no reason to stay in the capital." Zuo Zinan thought for a while and said to Liu Ruohuan: "It's better to do this. The garrison in the capital will be controlled by you to help Jinyang. Your Second Highness and I will go to Yiwei Mansion first, and wait until you deal with the Jurchens, and then meet with me and the Second Highness to resist the Hun army together."

Liu Ruohuan was stunned for a moment and said, "You come to the capital and don't take away any soldiers. Is it enough to rely on the soldiers on the border alone? Besides, the four troops in the capital have at least 100,000 people. Are you sure you let me take them all?"

Zuo Zinan shook her head and said, "It's okay. As long as the army supervisor progresses smoothly, it will naturally appear on the northern battlefield at a critical moment. And... Although the number of Jurchens is rare, they are all tricky people. I'm afraid your trip to Jinyang will not go smoothly."

When Liu Ruohuan saw that the other party had spoken to this point, she didn't say much.

The commander Zuo Zinan's words were repeated just now, and then he left the account to pass the message to various military camps.

Zuo Zinan bowed to Liu Ruohuan and said politely: "That military supervisor, we will see you next day."

"Young Master of the Zuo Family, you are welcome."

After Liu Ruohuan returned the gift, she watched Zuo Zinan come out of the handsome tent.

But for some reason, from now on, his heart was filled with uneasiness...

~

The army rushing to assist Jinyang City in the capital city set off, with a total of 120,000 military camps in the southeast, northwest and northwest, sailing out of the northern city gate and slowly heading towards the border between Shanxi and Henan.

On the carriage where Liu Ruohuan was riding, there was only a beautiful maid who was serving tea and pouring water, rubbing her shoulders and back.

"I didn't expect that you, the maid, did a dedication, and Ke'er's three-legged cat's skills were completely incomparable to you."

Sakurai Yuyu leaned over slightly behind him, and his silky satin-like thick hair fell on the side of Liu Ruohuan's face, making him feel itchy.

"A yellow-haired girl, how can I understand what a man wants?"

A scent of a woman filled his ears and noses, always stimulating his spirit and attention.

Liu Ruohuan was stunned for a moment and asked back, "Ker really asked you to monitor if I was flirting with the flowers? I feel like you are almost eating me..."

"Ha, my master is really good at joking." Sakurai Yuyu pressed her body intentionally or unintentionally, pressed against her snowy peaks, and laughed sweetly: "If you don't say it, who will know if you don't say it? Besides, if we cook the raw rice, what can others do if they have any opinions?"
