For a time, the rain of arrows on the two sides continued to come and go like flying locusts, but the dive shot was a big advantage, and for a time the Cao army suffered heavy losses. Yuan's army took the opportunity to attack the camp again, broke through the antlers, and almost destroyed the walled gate.

Cao Cao had to personally supervise the battle in front of the wall, and the soldiers shared the same hatred, so he guarded the gate of the wall. However, Yuan's offensive was very ferocious, and it held out until noon, and it was somewhat unable to resist the enemy.

At this time, the stone cart was built. Cao Cao sighed secretly, fortunately, he expected the enemy to take the lead, otherwise he would have been defeated. At the moment, he was busy pushing several stone carts made last night onto the wall. The boulder cart was very delicate and easy to load, requiring only the boulder to be placed on the stone platform.

Then press the mechanism, and you can eject the boulder several feet high, and the power is really amazing. At that moment, Cao Ying's several stone carts were aimed at the earthen ramparts, like earthen cannons, and smashed the archers on the enemy's earthen ramparts to death, dead and wounded, and countless casualties; Not to mention that the earth ramparts were smashed and changed shape, what are the advantages? For a while, no one dared to climb the earthen rampart to release arrows, and the Yuan army was even more terrified of the power of this thing, and they all called it a thunderbolt.

Yuan's army suffered heavy losses and had to collect troops and horses and give up high-altitude combat.

Yuan Shao gathered a group of strategists to plot to break the enemy, and all the strategists had no good plan, but when he saw the trial, he smiled and said:

"Since it is difficult to defeat the enemy in the air, go underground. I have a troop of diggers, who I have recently trained in secret, and who are very proficient in the art of digging. If this team digs tunnels, they can go straight to the enemy camp from our village, and they can attack the enemy camp at night......"

Yuan Shao nodded again and again when he heard this, and couldn't help laughing:

"It's really a good plan, a good plan, as you say."

All the strategists secretly praised the high plan of the trial, but they didn't know that the wall had ears, and they had already heard what Yuan Ying was planning clearly, and it was true.

Liu Ye entered Cao Cao overnight and said:

"My lord, Yuan Shao wants to dig a tunnel to attack the camp from underground."

Cao Cao frowned when he heard this, but said with a smile:

"If he secretly calculates, it will be troublesome, but now that he has anticipated the enemy's opportunity, it is simple. In this case, as long as men are sent to closely monitor the situation on the ground, as long as the approximate location of the enemy is detected, while he enters the camp and steals the village, he will surely win a great victory. ”

Liu Ye nodded hesitantly when he heard this:

"The lord is really scheming! However, there are masters in the enemy army to guide you! The last general heard that there was a road of men and horses and a digger army, and this road of people and horses was not trivial. In the past, Gongsun Chan stubbornly guarded Yi Jing, which was originally solid, and Gongsun Chan ran Yi Jing for many years, and the grain and grass were sufficient. I didn't want to be defeated in an instant, it was because this group of diggers hollowed out Yi Jing that Gongsun Zan died quickly. The speed of excavation is astonishing and unusual. But for several miles a day, it has been excavated at this speed, if there are more than ten groups, the lord is afraid that he will send troops to monitor it, and it will not be able to prepare, and it will be dangerous! What's more, this group of enemy troops is very proficient in underground excavation, and they will prevent our army from sending troops to listen, but they are afraid that it will be difficult to do anything. ”

When Cao Cao heard this, he knew that he had a clever plan, nodded and said:

"How do you think you should prevent it?"

Liu Ye thought for a moment and said:

"There is indeed a plan, so that the enemy army will go and never return."

Liu Ye whispered a few words in Cao Cao's ear, and Cao Cao couldn't help but nod his head again and again.

On the same day, Cao Cao ordered to dig a trench a foot deep in the village, and ordered people to prepare enough water to irrigate the ditch.

The generals don't know why, digging such a river in the village, and stepping on the bridge to go out of the village, which is very inconvenient. It's just that Cao Cao gave an order, and it's not too much. However, he said that everything went smoothly, and on the same day, he dug a deep trench that was about four or five meters wide and high enough for two people. At this time, there are already many strategists who know the battle situation and understand its meaning, but they do not expose the lord's old background, and when the battle is won, it is the quality that every minister should have.

However, he said that Cao Cao's side was ready, and Yuan Shao's side was almost the same, and the army had already been arranged, just waiting for the night to dig tunnels and attack the camp to annihilate Cao's army in one fell swoop.

Until the night, I saw the shovels of the Devil Army flying, and in the blink of an eye, they dug a tunnel leading to Cao Ying. These digging troops were trained by the trial and distribution institute, and they were very proficient in earth walking, and the tunnels they dug could accommodate one person to walk, and then there were soldiers who followed closely, and about 20 troops marched together to attack Cao Ying.

In less than four hours, these twenty tunnels led into Cao Cao's camp. However, it was said that when the devil army arrived at the deep trench of the camp, they only stabbed it lightly at the bottom, and they saw the sky of Cao Ying, and a sense of sudden enlightenment arose. It's just that there is a trench four meters high on it, and you need to climb up, all the soldiers, you look at me, I look at you, and nodded......

But he said that when he heard that Li Tong was in Cao Ying, he couldn't help but be overjoyed. Li Tong was in Cao Ying's abdomen, and if he shot from the inside, Cao Cao would have a big headache

Li Tong was the lieutenant of Yang'an at this time, and someone suddenly reported that a guest was visiting on this day. Li Tong invited the guests into the house, and the man saw Li Tong, but when he saw that Li Tong was very majestic, he said:

"You are Captain Li Tong?"

Li Tong smiled:

"Down there is Li Tong, who are you? How do you recognize Captain Pontus? We...... Doesn't seem like we've met before? ”

The messenger nodded, winked, and looked left and right. Li Tong was clear, waved his hand, and retreated. Then the messenger approached and whispered:

"General Li, I am Yuan Shao's envoy. On the orders of my lord, I have come to visit General Li. I have heard of the name for a long time, and it is better to meet when I see it today. My lord has always admired the general, and I hope that the general can accept the post of general of the south and serve my lord. ”

You must know that this general Zhengnan is not a miscellaneous general, and his official position is not small. Li Tong took the letter and glanced at it, and sneered:

"Yuan Highway is too underestimated by me Li Tong, right?"

Hearing what Li Tong said, he said with a smile:

"If General Li has any requests, just mention them, my lord admires the general, and he must meet the general's request."

Li Tong secretly laughed and frowned:

"Well...... Well, since you said so, I don't have anything else to ask for, just one request......"

Seeing that Li Tong had opened the conditions, he knew that there was a door, and hurriedly stepped forward and said:

"What does the general command?"

Li Tong looked at him and said in a low voice:

"I want something."

When the messenger heard this, he hurriedly said:

"What position does the general want?"

"No, it's not a position, it's the same thing."

"What's that?"

Li Tong looked at the envoy fixedly, and the envoy who looked directly at him was a little hairy, and Fang sneered and said:

"Your necklace is on the head!"

When the messenger heard this, his face turned white with fright:

"General Li, you ...... What do you mean? ”

Li Tong slapped the table and shouted:

"I, Li Tong, as a courtier of the Han Dynasty, how can I follow that Yuan Highway to be that rebellious minister? Come! ”

The soldiers outside had already heard the movement, and after listening to the general's order, Hu Lala broke in angrily, startling the messenger and looking at Li Tong in horror.

Li Tong shouted:

"Tie him up for me."

How did the messenger know that the situation had changed abruptly, and he was still soft-spoken, but now he turned his face and didn't recognize anyone, and said tremblingly:

"General Li, in front of the two armies, don't cut the envoys."

Li Tong looked coldly at this humane person who was dressed like an ordinary person:

"You're here too? Mixed into my territory, with bad intentions, and still don't tie your hands and get caught? ”

Someone had already stepped forward and pressed the envoy to the ground, and the envoy saw that Li Tong was stubborn and disobedient, and said in a hurry:

"General, wait, I still have a letter, which was specially instructed by the trial and matching military advisor to be handed over to you in person."

When Li Tong heard this, he frowned and said:

"He? Hum! ”

As soon as he thought of the trial, Li Tong was angry, tore the letter to shreds, and threw it on the ground:

"Originally, I wanted to spare your dog's life, but I dared to use his letter to press me! Someone, dragged out and cut down. ”
