After being abandoned by Liu Bei, Cao Cao begged me to be a military adviser

Cao Pi said: "Mr. is knowledgeable and talented. I still have a lot to learn from him!"

"It's up to you!" Cao Cao said, "Be careful, Liu Xian has already guessed that you are my son!"

"You guessed it all?" Cao Pi was puzzled: "How did you guess it?"

"Idiot!" Cao Ji said: "You dare to run into the camp as a small school official, which is doubtful in itself!"

"I was negligent!" Cao Pi lowered his head silently.

"Haha!" Cao Cao smiled, and patted his son on the shoulder vigorously: "Stay hard by your side and work hard!"

"Understood dad!" Cao Pi showed a smile on his face.

The conflict between father and son finally eased.

Cao Cao let go of the stone in his heart, got into the carriage and drove away.

Chapter 42 Cao Cao flooded the tunnel, Yuan Shao was blown up

After returning to Daying, Cao Cao summoned several counselors.

"Zhongde, you guys plan a river for me, and then let Cao Hong dig it!"

"The river course?" Cheng Yu looked puzzled.

Xun You asked, "Prime Minister, what are you doing digging the river?"

Jiang Gan suddenly thought: "Could it be that the prime minister is going to use the water of the Yellow River to flood Yuan Jun's camp?"

As soon as this remark came out, everyone looked at Jiang Gan.

Jiang Gan shook his head: "Yuan Jun is upstream, our army is downstream, it's unrealistic!"

Cao Cao snorted coldly, and explained: "In the battle last night, Yuan Jun's vanguard lost thousands of people, but this does not mean that their plan of digging a hole is not feasible. Our army must plan ahead and completely put an end to Yuan Shao's delusion!"

"The prime minister is right!" Cheng Yu nodded, "But can digging a river channel put an end to Yuan Shao's delusion?"

"Hahaha!" Cao Cao laughed, but did not explain.

"Yes!" Liu Ye nodded: "Choose a suitable location in the center of the confrontation between the two armies to dig deep into the river. If Yuan Jun digs another hole, the water of the Yellow River will flow back and kill himself!"

"That's right!" Cao Cao smiled, finally someone understood what he meant.

"The prime minister is brilliant!" Cheng Yu waved his hands to Cao Cao.

Liu Ye asked, "May I ask the prime minister, is this the strategy proposed by Mr. Cao Ji?"

"Exactly!" Cao Cao nodded.

"Tall! Mr. Cao Ji is tall." Liu Ye repeatedly nodded.

"Admiration, admiration, beyond compare!" Jiang Gan followed suit.

Cao Cao's face is full of smiles, as long as people around him praise Cao Ji, he always feels that these people are complimenting himself.

After many discussions among several people, a relatively reasonable river excavation route was finally planned.

Cao Cao divided the road map of the river into three parts and handed it over to Cao Ren, Cao Hong and Xiahou Dun to excavate each part.

The external statement is to strengthen the defensive position.

It is also common for the two armies to fight and dig trenches.

Yuan Shao didn't react after hearing the news.

In his opinion, the worst possibility is that Cao Cao also has to dig tunnels for himself.

But Yuan Shao is not afraid. Cao Cao can only steal things when he digs tunnels, but he is definitely a professional in tunneling and fighting.

Both armies are digging in full swing, Cao Jun is in the open, and Yuan Jun is in the dark.

One morning ten days later, Yuan Jun, who was advancing through the tunnel, suddenly found that it had been hollowed out.

Straight ahead was a ditch.

To be precise, it was Yuan Jun who connected the cave with Cao Jun's river.

Zhang Duwei, who survived the catastrophe, returned to the camp to report to Yuan Shao in person.

"What?" Yuan Shao was shocked: "The tunnel is connected to Cao Jun's ditch?"

"That's right!" Zhang Duwei said, "This ditch is so long that you can't see the end at a glance!"

Yuan Shao didn't speak, but looked at Guo Tu.

Guo Tu shook his head: "Master, I don't know what kind of medicine is sold in Cao Jun's gourd!"

"Hahaha!" Xu You laughed.

"What are you laughing at?" Yuan Shao looked at Xu You.

Xu You said: "This must be Cao Cao's defensive strategy. Cao Jun only needs to keep an eye on this ditch, and our army's tunnels will not be able to advance any further!"

Upon hearing this, Guo Tu became unhappy: "Why can't our army advance? It's nothing more than changing the route!"

Xu You said coldly, "Why is it so simple?"

"Then try it!" Guo Tu cupped his hands to Yuan Shao: "My lord, I suggest that the tunnel be dug deep and pass under Cao Jun's ditch, so that it will still be invisible.

"It makes sense!" Yuan Shao immediately ordered Zhang Duwei to change his course.

Cao Jun's river is connected to Yuan Jun's cave, so naturally Cao Jun can't hide this matter.

After Cao Cao learned about it, he immediately ordered the water to be released.

That night, the Yellow River water poured into the river.

As the water flow increased, the river channel suddenly collapsed, and then a vortex appeared.

Zhang Duwei Jinzhi, who was digging a hole under the river channel, survived burning himself, but now he was drowned by the backflowing river water.

Not only Zhang Duwei, but other Yuan soldiers who were digging tunnels also suffocated in the caves.

The raging river flooded all of Yuan Jun's tunnels.

Even the tunnel entrance of Yuan Shao's camp started to spray water.

Some unreasonable soldiers shouted: "Water is coming out of the well, that's great, I don't have to go to the river to fetch water from now on!"

But as the body floated up from the tunnel mouth, the soldiers realized the seriousness of the matter.

When Yuan Shao heard the news, the camp had already been flooded.

"What's going on, what's going on?" Yuan Shao roared in the central army tent.

Xu You shook his head: "My lord, my lord, what else could be going on? Cao Jun must have poured water into the ditch, and now the river is backfilling!"

Yuan Shao said: "Where did Cao Jun get the water?"

Xu You smiled: "The Yellow River is right next to it, why worry about no water?"

Yuan Shaoqi's old face turned purple eggplant color.

Yuan Shao said angrily: "Cao thief, this dog Cao thief is too shameless!"

While speaking, Guo Tu hurriedly ran into the big tent, his whole body was drenched.

Yuan Shao stared at Guo Tu, didn't say a word, but seemed to say everything.

"My lord, calm down!" Guo Tu clasped his fists together, "Our army has already filled up the hole, temporarily blocking the flooding of the river!"

"Filled in?" Yuan Shao frowned: "The tunnel was dug for several days, and you filled it up in the blink of an eye?"

Guo Tudao: "My lord, I don't know something. If I don't fill in the river, I'm afraid the river will not be able to stop the backflow!"

Xu You taunted: "Lift a rock and shoot yourself in the foot!"

Guo Tu bowed to Yuan Shao: "It's my incompetence and mistake, please punish me, my lord!"

Yuan Shao waved his hand and said, "It's that thief Cao who is treacherous, it's not because of your incompetence, let this matter go!"

"Thank you, my lord, for your comfort!" Guo Tu bowed and said, "Since Cao's army can divert the river, our army can also send troops to block it!"

Xu You smiled: "The river is blocked, should we continue digging the tunnel?"

Guo Tu was displeased: "What do you mean?"

Xu You snorted coldly: "This is just a child's rogue trick. The two armies are fighting each other for logistics supplies and food supplies!"

Yuan Shao said: "What countermeasures do you have?"

"Continue to consume!" Xu You said: "Our army has a steady stream of supplies and abundant food and grass. Although Cao Cao is backed by Xudu, there is constant famine. If we persist for a long time, we will retreat without fighting!"

Guo Tu snorted coldly: "Isn't this nonsense?"

"I haven't said anything yet!" Xu You said: "If my lord is eager to win, you can choose the opportunity to divide your troops and attack Xudu by detour!"

Guo Tudao: "The advantage of our army is that it has more troops than Cao's army. How can we divide our forces at this time? If Cao Cao fights to the death, how should we deal with it?"

"How dare Cao Cao?" Xu You said, "If he fights to the death, even if he wins the battle, he will lose everything!"

Guo Tu retorted: "If Xu is lost, you can still call back. If our army camp is lost, then everything will be lost..."

The two quarreled in the big tent.

"Okay, shut up!" Yuan Shao yelled angrily, "I'll go back to the tent and reflect on you two!"

"Follow orders!" Guo Tu and Xu You bowed their hands one after another, and withdrew from the Chinese army tent.

The two looked at each other, full of hostility.

"Hmph!" Guo Tu snorted coldly, already hating Xu You to the bone.

If he caught Xu You's pigtail, he would definitely not let him go.

Chapter 43 Xudu is undercurrent, Liu Xiandao breaks the secret

Following the failure of Tushan's archery harassment and the failure of tunnel digging, Yuan Cao's confrontation entered a calm period.

But the surface is calm, but the undercurrent is actually surging.

Guo Tu offered another new strategy, sending people to Xudu to instigate rebellion against the officials of the DPRK and China.

Naturally, this cannot be hidden from the school affairs office.

The school affairs office immediately sent someone to the front to report the matter to Cao Cao.

Cao Cao was shocked when he heard this.

Now Xudu's military rations are in a hurry, and they need to transfer rations from Xuzhou, but Xuzhou is far away from Guandu. Once the military rations are delayed, the army will be in chaos.

Moreover, the previous method of team transportation is not suitable for such long-distance grain transportation.

The issue of food and grass has not been resolved yet, yet Yuan Shao has started to act like a moth again.

Cao Cao had a big head, and then subconsciously thought of Liu Xian.

His intuition told him that Liu Xian would definitely be able to help him through the predicament.

"Xu Chu, take two altars of good wine and follow me out of the camp!"

"Yes, Prime Minister!" Xu Chu shouted vigorously.

After more than an hour, Cao Cao brought Xu Chu into Liu Xian's small courtyard carrying two jars of good wine.

To Lao Cao's surprise, Lao Huang was roasting chicken again.

"Oh, Master Ji is here, please, please!" Lao Huang stood up and greeted the two of them.

Lao Cao sat down with a smile, and asked Lao Huang: "Old Huang, your husband's food is good! Every time I come, I can see you roasting chicken!"

Old Xu asked: "Where did this chicken come from? Didn't you see chickens raised in the yard?"

"Hey!" Lao Huang grinned: "You will understand even if I don't tell you. You may not really understand some things if I tell you something, so whether I tell you or not has nothing to do with whether you understand or not!"

Old Xu: "???"

Lao Cao smiled bitterly: "Why, your husband also said that?"

"Yes!" Lao Huang nodded: "My husband usually talks like this!"

Old Cao said: "Then can you speak human language?"

Old Huang: "This..."
