Yang Song didn't know that his second child was about to come to life, and he was now meeting Chen Ping in the study.

In fact, what can I do if I know? Can he leave behind the military affairs before and go outside the delivery room door anxiously to guard it?

Even if he goes, what can he do? He can only be anxious!

Yang Song also knew that he had no time to pay attention to these things when he was busy, so he invited all the doctors and the wife into the mansion so that he could do things with peace of mind.

Since Yang Song got married with Xiaolan and Xiaojuan, he has recruited some servants, which is necessary. It is also since these maids and old wives entered the monarch's mansion that this huge mansion became a little angry!

"Your Majesty, yesterday's battle ended after the enemy retreated in a hurry. Today's battle was very fierce. The enemy's soldiers were completely crazy and attacked the pass desperately!" Chen Ping was given the morning battle report and quickly reported to Yang Songhui after he sorted out the battle report.

Yang Song frowned and looked at the battle report. Yesterday, the enemy's tentative attack, Ben Di Qing easily repelled, and he thought the enemy was going to calm down for a while, so today he dared to tease the child in the back garden so leisurely.

But he didn't expect that the enemy army would dare to push forward the entire army to fight after a hasty test yesterday, which was beyond his expectations!

Yang Song read the battle report, put it down, and instructed Chen Ping: "Okay, Gu knows, pay attention to it. If you have any questions, you must report to Gu as soon as possible!"

"Yes, I obey the order!" Chen Ping was originally here to deliver the war report, but now he has just fulfilled his responsibilities.

After Yang Song watched Chen Ping away, he hurriedly opened the small map, enlarged it to Tianqian Pass, and carefully looked at the actual battle situation.

I saw that outside the first city wall of Tianqian Pass, the bodies were almost piled up to the height of the city wall. You must know that this is a city wall that is fifteen meters high - how many people died!

Time goes back to the morning of the day before the war begins.

"Report~! Report to the general, the enemy launched a charge of the entire army!" The guards outside pushed open the gate of the city tower and reported to Di Qing who was thinking.

At this time, Di Qing raised his head from the sand table, listened to the shouts coming from outside the city wall from outside the door, and hurriedly picked up the monocular telescope placed beside him, and in two steps, quickly made the city tower, came to the city wall, looked towards the telescope, and looked out along the gap in the daughter's wall.

He saw the dense enemy troops charging desperately. The front row was supported by simple shields, and then there were many soldiers carrying long ladders behind him. Under the command of the officers in the military formation, they all charged upwards with all their might!

The slope outside the Tianqian Pass is divided into three parts. The closer it is to the city wall, the larger the slope. When it reaches more than 100 meters in front of the city gate, the slope is more than 30%. On this steep slope, there is a groove every thirty meters, which is prepared for the accelerated guidance of the stone ball.

The slope in the middle part is a gradient gentle slope that drops from 20% down by 10%, and this distance is two or three kilometers. The slope in the bottom last part will gradually become smoother, and the distance is the entire channel.

Slope refers to the degree of steepness of the surface unit, which is usually expressed as the percentage of the vertical height of the slope and the horizontal distance. For example, five percent of the slope refers to the vertical rise of five meters for every 100 meters ahead of the horizontal direction.

The location of Tianqian Pass is located in the middle of the mountain range, which is one or two kilometers high from the gentle ground.

Therefore, although the enemy soldiers charged towards the top, they still ran very fast. It only took about ten minutes to reach two kilometers from three kilometers, which was exactly the same speed as the army tested yesterday.

Seeing the enemy launching a general attack today, Di Qing was a little incredible. Logically speaking, wasn’t it necessary to completely test the defensive power before launching a general attack? What did the enemy’s commander think? He worked so hard!

Yesterday's temptation from the enemy gave Di Qing a feeling that the enemy's commander was a steady and steady person. I didn't expect that he would surprise him today, but is this useful?

Suddenly, Di Qing saw a row of large equipment being pushed out from behind the enemy's army in a telescope. It looked like it was a stone thrower and a stone thrower!

"Bang the war drum! Blow the trumpet! Raise the battle flag!"

"Command! The siege cannons load solid bullets, and the target large equipment behind the enemy!" Di Qing looked at the large equipment in the distance, and felt uneasy in his heart, so he ordered the siege cannons with the farthest range to destroy the opponent's equipment.

After giving the order, Di Qing felt relieved. After watching the enemy in front of him entering a kilometer range, he charged even more and then issued a series of orders.

"Order! Field artillery and city defense cannons are filled with flowering bullets, targets, enemy troops outside the city!"

"Order! The powerful crossbowmen and archers prepare for three-stage coverage shooting!"

"Order! The crossbow soldiers are ready and fire freely after the enemy enters the range!"

"Order! Each melee soldiers on the city wall are ready to take the enemy!"

"Order! The Rolling Stones are continuously put into place and prepare!"...

Di Qing put down his telescope and looked at the dark enemy soldiers under the city, surging towards the solid city wall like waves, but the result they were waiting for was already destined!

"The long-range artillery is ready!"

"Field artillery, the city defense artillery is ready!"

"The Rolling Stone is ready!"...

In less than a minute, a messenger reported to Di Qing one after another that the preparations of the troops were completed.

“Logistics support is ready!”

At this time, Lu Su's familiar voice sounded in Di Qing's ears. Di Qing turned his head and looked at Lu Su sternly. Lu Su hurriedly clasped his fists and reported: "General, there is Yu Shuyu in the logistics support side, so you can rest assured!"

Lu Su also knew that the war was urgent at this time. If he left his post without permission at this time, resulting in insufficient logistics supply, it would cause very serious consequences!

So he roughly explained his purpose here with a very fast speech speed: "Staff Yu's ability is very worthy of recognition, and he can handle it completely. He also took the initiative to ask his subordinates to assist the general in defense!"

After hearing Lu Su's explanation, Di Qing nodded and replied quickly: "Okay! Just go and see if there are any loopholes!"

Di Qing only heard Lu Su's voice throughout the whole process and looked at Lu Su with a stern look. During the rest of the time, he was staring at the movements of the enemy outside the city.

"Yes! General!" Lu Su also knew that Di Qing was under great pressure now, which means that he had a serious matter. If others did this, if they were not careful, they would be subject to battlefield discipline!

How much pressure is Di Qing? As long as you know that this war is related to the life and death of the people across the country, you will know. In other words, he now shoulders the lives of the emperor, himself, and these tens of thousands of soldiers, and 300,000 ordinary people!

Under such great pressure, he can still stand calmly and steadily on the city wall to command the battle. What kind of psychological quality is needed! - It makes people feel awe-inspiring when I think about it!

Watching the enemy's rapid rushing through the nine hundred meters forward, Di Qing raised his right hand.

The messengers next to him stared at his raised right hand, waiting for the moment it fell!

Eight hundred and fifty meters! The right arm, which was in the "long-awaited" gaze of the messengers, fell down!

"Fire the gun~!"

"The general has an order~! Fire a cannon~!"

With the yell of the messenger, the flag standing on the high place quickly waved!

"Dongdongdongdongdong~!" "Woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

The sound of war drums and horns resounded throughout the pass inside and outside!

After waiting for a long time, the artillery commander officer looked at the order of the order flag, he waved the red triangle flag in his hand heavily!

"Fire the gun~!"
