After fifteen days of marching, Wu Yueya came to a flat land, and a hundred miles ahead was Tongguan.

The three-zhang high wall made of earth and stone, covering an area of more than 10,000 hectares, is the junction of the Yellow River and Weishui in the north, and is an important pass connecting Chang'an and Luoyang.

Looking at the garrison on the city wall through the binoculars, what came into view was a wolf flag of the Hu people, and down was the Hu people's sergeants, mainly crossbowmen, and a large number of rolling logs and falling rocks were prepared, and Wu Yueya even saw the smoking oil pot.

"Princess, how can we attack the city, there is not even a ladder?" Ji Xiao held the monoculars upside down, pretending to look at the wide fortress wall in front of him, he had seen the battle, and he had never been cowardly on the battlefield, when he was defending the city, he saw what chariots and ladders kept appearing, but Ji Xiao didn't see any siege equipment in the Black Armor Army at all.

"No need to attack, they're out!" Wu Yueya took the telescope and saw that the only remaining large city gate in the middle was opened, and rows of Hu infantry came out of it.

But Wu Yueya was surprised to find that many slaves also appeared, not a lot, it can be described as innumerable, those who were tied were both soldiers wearing half armor, and people in rags.

Looking further among the people, there were old men in their seventies and eighties who walked on the ropes, children who were not yet adults, women who hid their faces and wept, and young people who looked at death with resolute expressions.

Wu Yueya clenched the Yundan Han Sword in her hand, put away the binoculars, and her originally soft gaze instantly erupted with anger, as if she wanted to devour those Hu people who could be seen alive, she pulled out the Han Sword with a strong hand, and the killing aura emanated from Wu Yueya's body, which was a momentum tempered by the battlefield for a long time.

"Princess?" Du Fu rode forward, looked at the princess with a faint anger in her beautiful eyes, and sighed slightly, the princess is not an unrighteous person, for the despicable methods of the Hu people, she can't bear to see through it at a glance, after all, someone still has to give an order, "Princess, Du thinks that you should first use a crossbowman to test it, and then use the sky cannon to advance!" ”

Wu Yueya looked at Du Fu, and then at the generals who were also observing the situation ahead with a monocular, and asked Du Fu, "Zimei, do you remember the original intention of the establishment of the Black Armor Army?" ”

"Naturally, I remember that in order to save the people from fire and water, the princess's decision... Du Fu understood! Advance with shield soldiers as a platoon, and arrange a column of long sword soldiers and sword soldiers in every other rank, and each long sword soldier and sword soldier is equipped with a crossbowman to rescue the people! After listening to the princess's words, Du Fu immediately made the next strategy.

After listening to this, Wu Yueya nodded, continued to hold the telescope and continued to look ahead, and found that the Hu people took these innocent captives as the front row, and they were hiding behind, mainly advancing with infantry, and did not see cavalry, Du Fu's rescue strategy was no problem.

In the binoculars, Taketsuki saw some discordant images, most of the young captives, mostly men, who looked emaciated, but in fact these people had been looking around, and they were out of step with those who were being escorted to the front row, who thought they were going to die.

"Wait!"

"Does the princess have any other commands?"

"When giving the order, it is important to make it clear that among the prisoners in the front row, there are many lurkers who may be Hu people, so let the sergeants pay special attention to those young men, and at the same time, notify the artillery battalion, set up guns on the left and right, and be ready to strike at any time!" Wu Yueya put down the binoculars and put the Yundan Han Sword into the scabbard.

"Du Fu understands!" Le turned the horse and slowly walked towards the military formation behind him, as the princess's military advisor, Du Fu was no longer the down-and-out prodigal son, from running a business to commanding the army, from a sailor to a qualified captain, especially their black armor army, which is completely different from other armies, new firearms, can make a big splash, this is the pride of their black armor army!

"Herald! Fang Shan's body, the shield soldiers formed a hundred phalanxes of twelve by ten! Then select a hundred swordsmen in a formation of five or five, and the two will change into a formation! Beware of the disguised Hu people in captivity! In this battle, we must save those innocent captives as much as possible! ”

"Yes!"

Du Fu watched Fang Shan dismount and quickly run towards the sword and shield soldiers in the left formation, and then looked at Lu Ziji who looked over, "General Lu, the big sword soldiers dismount and fight on foot, select a hundred seats in a five-five formation, and unite with the sword and shield formation!" Watch out for the pretenders among the captives! ”

"Ziji takes orders!" Lu Ziji held the spear, dismounted, and personally changed it into a big knife and walked towards the big knife camp.

Seeing his own regiment commander marching towards the military formation, Ma Daha also followed, but said in his heart how did our general forget him, this expedition, Ma Daha drunk Ma Erha, and drugged him, by the way, he looked for a matchmaker, and arranged for Erha to go to Jiannan to marry the orchid who lived next door.

Du Fu looked at the figure of the two of them, nodded and smiled, everyone knew that General Lu liked the princess, and now that he was in his age, he still guarded the princess alone, and wanted to get the princess's heart, but unfortunately, Du Fu knew that the princess had no intention of having children at this time, and was dedicated to the country and the people.

"General Gu, head of the regiment, please pass the order to turn the crossbowmen into infantry, two rows and ten columns, follow two rows behind the sword and shield, and make a response! Beware of the pretenders as well! ”

"Yes! Strategist! ”

After Du Fu finished speaking, he personally walked in the direction of the artillery battalion, and the artillery battalion was under his command, and soon arranged the 10,000 artillerymen, and then came back to give an order to Cen Shen, "General Cen, please go and dispatch the cavalry, and the remaining sword and shield soldiers and sword and spear soldiers will stay with the princess to respond!" ”

"Leave it to me!" Cen Shen raised his head and took a sip of spirits, for him, there were no taboos, and Taibai was compared, and Le Ma walked towards the military formation behind him.

"General Cen, pay attention to your body and drink less spirits!" Du Fu advised, but he didn't expect the other party to directly pick up the wine gourd and throw it over, so he had to catch it.

"Master Du, please help me save this pot of fine spirits! I don't have a hand to protect my wine on the battlefield! Cen Shen waved his hand, laughed and said, carrying a spear and riding a horse into the military formation, his bold feelings overflowing with words.

"Haha! Good! Du Fu also laughed happily, stroked his beard, followed the princess to the present, commanded the army, glanced at the wine gourd, smiled, picked up the wine gourd, took a sip, and roared to the sky.

Cen Shen glanced back at Du Zimei, proudly clenched his spear, and looked at the black-armored sergeants with blazing eyes. The enemy is indestructible!

The blood in his chest was boiling, but he muttered in his mouth, "Fortunately, I joined the Princess Protector's Mansion under the recommendation of Gong He!" ”

In front of Tongguan, tens of thousands of captives were pushed to the front of the formation as a shield, the Hu Renbu Brigade was behind, a long line appeared in the plains, the lonely flowers of mourning withered with the wind, and a wind blew from the Yellow River, with some moisture dyed the face of a girl at the front of the array.

Wu Yueya looked at the formation of the black-armored military formation in front of her, like an indestructible steel battle formation, and her steps were neatly advancing, a gust of wind was blowing, and the arrow wound on her arm was still aching.
