A slight sound of propeller rotation came from my ears.

Through the glass curtain wall, the lush forests and land are fully visible.

The thin clouds in the sky are often a symbol of clear weather.

Those low and thick clouds are a sign of rain, wind and snow.

And clouds like today that look light and ethereal and freely curled are called cirrus clouds.

This kind of cloud is very thin, and the sun can shine on the ground through the clouds, and the light and shadows of the army and trees are still very clear.

The curly clouds float in strands, sometimes like a white feather, sometimes like a piece of white gauze.

Occasionally, by chance, they are arranged in groups in the air, as if the water surface blowing by the breeze has created neat ripples.

The glass curtain wall could not block the sun, and Xi Yunfei stood for a while and was dazzled by the sun.

Li Yuan was lying on the table observing the map, muttering a few words from time to time, making a sound of laughter.

Princess Yicheng sat aside and looked at the scenery outside the window. Although it was not the first time she took an airship, from this perspective, her mood and thoughts seemed to be sublimated.

"Boy, come and have a look." Li Yuan waved to Xi Yunfei and said, "If Yuan Gai Suwen led his troops to garrison Jian'an City, will the other cities be short of troops?"

Xi Yunfei and Princess Yicheng were both stunned when they heard this. They hurried to the map, where there were a few wood warriors.

"A terracotta warrior represents five thousand troops. This is the regular defense of a city. Look... Jian'an City originally had 30,000 defenders, but judging from the information sent back by Cui Escort, the number of troops was at least 50,000, that is to say, the additional military force was 20,000, and these were not from nothing. They must be the men mobilized by Yuan Gaisuwen from other cities."

Xi Yunfei nodded thoughtfully and looked down at Jian'an City on the map. At this time, there were ten warriors on it, representing the 50,000 army. To the west of Jian'an City, six warriors were placed, representing the 30,000 army of Cui's army.

According to "Zuo Zhuan" and "Shi Ji", in ancient times, siege of cities required at least five times the troops, but if the commander had outstanding ability, three times the troops were enough to attack the city.

However, now, I thought that with Xi Yunfei's help, the Cui family's 30,000 army should not be afraid of attacking the 30,000 army in Jian'an City, but I didn't expect that a Yuan Gai Suwen would come out halfway, and there would be an additional 20,000 army.

If Xi Yunfei's purpose was to expand the territory, it would be possible to sweep it with thermal weapons, and there was no need to cause such trouble. But in fact, Xi Yunfei needed these Goguryeo people very much, and it would be a loss for him to die.

There is no way, the human power of this era is too precious.

Li Yuan didn't want to get a Goguryeo that was blown to ashes, otherwise the battle would be too bad.

"I have an idea."

"Tell me quickly." Princess Yicheng glared at him angrily.

Li Yuan pursed his lips in disappointment and said, "Jian'an City is now well-deployed. We can avoid its edge and attack several other cities first. For example, this An City is closest to Jian'an City. It is possible that the additional troops from Jian'an City were mobilized from here."

Xi Yunfei nodded after hearing this and said, "The information we collected before showed that this Anshi City has only been built for a hundred years, the city is not big, and the defenders are only 20,000. It is really possible that as you said."

"In other words, Anshi City is an empty city now?" Princess Yicheng's eyes lit up.

Li Yuan glanced at him: "Anshicheng is not your Yang family's goal. Even if there is a cheap price to pick up, it will not be your turn."

Princess Yicheng was about to get angry, "Cough cough", Xi Yunfei coughed twice and said, "I remember Anshicheng is the target of Lu's family."

Li Yuan nodded slightly: "No, it's a bargain for them."

Xi Yunfei smiled casually, took out the cell phone in his arms, adjusted it to the corresponding channel, and said, "This is the command center, I'll look for Lu Chengqing."

"……yes."

Soon, Lu Chengqing's low voice came from his phone: "Mr. Lang, please tell me."

Xi Yunfei looked at Li Yuan and put his phone on the table. Li Yuan was very curious about this magical object, but now it is not the time to study it deeply. He put his head over and said, "Lu Chengqing, your 20,000 people in the Lu family will leave the team immediately and arrive at Anshi City as soon as possible and wait for no mistakes."

"Anshicheng?" Lu Chengqing's voice was a little confused. After a moment, he responded in a constant tone: "Received."

When Li Yuan heard this, he nodded with satisfaction, very satisfied with Lu Chengqing's attitude. If he had changed to the heads of several other aristocratic families, he would have to ask him thoroughly.

Seeing that Li Yuan had no intention of explaining, Xi Yunfei thought about it and said to Lu Chengqing: "Uncle Lu San, we received a secret report. Jian'an City has an additional 20,000 defenders for no reason, and Anshi City is closest, so..."

"So that's it... Xie Langjun reminded me." Lu Chengqing's voice finally changed a little, no longer as calm as before.

After the call, Li Yuan said with some savory taste: "Everyone said that Anshicheng was of no value. Even if Lu took the big price, he would lose all his money. Humph, I don't want others to go directly to pick up the ready-made ones."

Princess Yicheng was also a little envious. It was the most perfect result to be able to win a city without bloodshed. Unfortunately, such opportunities are hard to come by.

Xi Yunfei smiled helplessly at them, thought for a while, turned his head to the guard at the door and said, "Go and notify Zhuge Qing, let the No. 2 airship follow the Lu army, ready to provide support to them at any time."

"It's just an empty city, there's no need?" Li Yuan said.

Xi Yunfei shook his head: "I'm not afraid of ten thousand, I'm afraid of anything."

That night, the army camped on a wasteland.

The bonfire soars into the sky, and the meat is fragrant. Several families have a deep foundation. Even if they have enough food and drink, they are not afraid of not having any oil or water.

Cui Shang sat in the big tent, and the capital was filled with the heads of several aristocratic families.

"Everyone, we will pass the Tang Dynasty tomorrow, and we will part ways. Here, Cui wishes you all in advance to win the championship."

"Hahaha, I wish you the same wishes!"

Everyone drank the glass of Chinese wine in one go.

Wang Shou of Wang put down his wine glass and asked Lu Huan sitting opposite him: "Master Lu, I heard that your Lu family 20,000 troops have already headed north in advance, but what kind of news did you receive?"

Lu Huan, also known as Lu Jianting's biological father, is now the head of the Lu family in Fanyang.

"Haha, the head of the Wang family is joking. My third brother is also entrusted by my husband. Since the husband wants us to go north in advance, I, Lu, must have no choice but to do anything about the news... Haha, I can't say much."

When the heads of the family heard this, they all looked shocked and suspicious. Only Cui Shang, the leader, looked at Lu Huan without any trace, with a hint of helplessness in his eyes and unconcealed envy.

There is no way, Cui suffered a great loss this time, and Lu's family won the advantage, can Jian'an City be taken safely? How many benefits can you get after taking it? It's still unknown. If he had known this, he would rather have an empty city without defenders.

Just as everyone was chatting, Xi Yunfei, who was having a meal, received another secret report.

"Yun Gaisuwen led an army of 30,000 to set up an ambush outside the city?"

Li Yuan was surprised when he received the news, thinking that this Yuan Gai Suwen was really brave and resourceful. He didn't want to seize the city and defend it, but instead took the initiative to attack. It was a brave general.

If Xi Yunfei had not arranged an airship to test the enemy situation early in the morning, it would have been a big loss for Cui's 30,000 troops.

"Haha, this old Cui really has to thank you." Li Yuan immediately spread the map.

Xi Yunfei placed six terracotta warriors representing the Goguryeo army on both sides of a valley.

The two frowned and pondered for a while, and Li Yuan's eyes suddenly lit up: "I have a clever plan!"
