Three Kingdoms open plug-ins everywhere

"The Marquis of Weihai is erudite, so he can compete in poetry and prose; the Marquis of Weihai is erudite, so he can cover the world; There are strategies.

Take Huoshao Changshe as an example, if Weihai does not know astronomy and geography, how can it know the change of the wind direction, and if it does not know the art of war, how can it predict the enemy before repeatedly killing the enemy general.

As the saying goes, it is better to travel thousands of miles than to read thousands of books. A person like Marquis Weihai who knows how to plan in advance will definitely enter Bingzhou from Hanoi County, because he has been to Jizhou and has a basic understanding of it, so he will not It's a waste of opportunity to go there. "

Facing Cheng Shu's eloquent talk, everyone couldn't help but be convinced, it seemed that what he said made sense.

Cao Cao himself nodded frequently, especially when he understood the meaning of Cheng Shu's last sentence.

A noun suddenly popped up in my mind.

Gather geographic intelligence.

All the key points of Chengshu are actually talking about this.

This is the key point. He concluded that the purpose of Xu Ding's decision to cross the river in Yanjin was to collect the geographical situation of Hanoi in advance.

If Xu Ding was here, he would definitely applaud Cheng Shu when he heard Cheng Shu's words.

It must be unexpected that there is such a person in the Three Kingdoms who has not left a strong name in history, and he can guess his intentions.

For a handsome man, map guns are the most taboo.

The battlefield is a combination of three aspects: weather, location, and people. The situation in each place is different. An understanding of geography can help plan ahead for the generals.

Don't talk about the bloody lessons of a certain party's fifth anti-encirclement and suppression campaign in later generations, just talk about the Three Kingdoms and the Warring States period. There are Ma Di and Zhao Kuozhi who talked about armies on paper, map guns, and the disaster is not shallow.

So Xu Ding naturally likes to travel thousands of miles, travel all over the mountains and rivers of the Han Dynasty, and understand the geographical conditions of each place clearly.

That's right, he has been to Jizhou and has a basic understanding of the situation in that area, so he chose Yanjin to cross the river from Hanoi to Huguan and enter Bingzhou, so that he can understand the situation in Hanoi County, Shangdang County, Taiyuan County and other places , for future planning reference.

Even quietly draw maps.

"I see. No wonder Bokang is so powerful." Only then did Cao Hong, Cao Ren, Xiahouyuan, Xiahoudun and others suddenly realize.

Then one by one looked at Cao Cao expectantly.

As their eldest brother, Cao Cao has never lacked courage and courage, let alone tolerance and wisdom.

If he can do it, he believes that his elder brother can do it too.

Cheng Shu's analysis was in place, but Cao Cao still said a little unconvinced: "There is only one Bokang in the world. Even if someone can imitate him, he will not be able to become him in the end. We have to learn from Bokang, but there are some things we still have to learn because of it." People are different, choose what you want.”

"What elder brother said is true." Everyone in Xiahou's family of Cao's family replied after hearing the words.

Cheng Shu and the others said, "My lord is wise!"

Since Xu Ding had a nine-story chance of crossing the river in Yanjin, Cao Cao felt relieved and was about to speak when he heard a few noises not far away.

"Who is Cao Cao? Not interested!"

It turned out that Tian Yu came to Yanjin, but was mistaken by Cao Cao's diners for coming to vote for Cao Cao, so he received him warmly.

Then Tian Yu, who had not traveled far, thought highly of himself and was proud, ruthlessly retorted.

God is sorry, he really doesn't know Cao Cao.

Cao Cao's reputation at this time was limited to the vicinity of Luoyang, Jinan, and his hometown Qiao County. Except for some big families, there were not many people who knew him.

So Cao Cao was ignored by Tian Yu.

After finally arriving in Yanjin ahead of time, Tian Yuyi was extremely tired and wanted to find a quiet place to rest, so he hated this group of guys who took the initiative to ask questions.

"Boy, what did you say?"

A diner from Cao's family was a little upset, and said in a rough voice: "How dare you ignore my lord like this, boy, did you come here on purpose to find trouble?"

"Sorry boy."

Others also echoed.

They recruited righteous men for Cao Cao in Yanjin, and the heroes around them all came to join them and planned to go to Bingzhou to kill the enemy. In the end, a boy who didn't even grow up ran out. He thought he was a character, but he despised them.

"Apologize to your sister!"

Tian Yu rolled his eyes angrily, then walked away.

He is the number one Wu Shao in Yuyang, it is ridiculous to want him to apologize.

Besides, he was not wrong.

Who is Cao Cao?

God knows!

"Zheng!"

A long sword was drawn out of its sheath, and it landed five inches above Tian Yu's chest with a soft sound.

Chapter 171 Cao Cao wants to accept Tian Yu

Chapter 171 Cao Cao wants to accept Tian Yu

Tian Yu's words are very hateful. Originally, there was not much misunderstanding between the two sides, but the words of both sides were a bit reckless and fierce, so the atmosphere suddenly reached a point of tension.

"I want to do it!"

Tian Yu squinted at the man who drew the sword, raised his eyebrows, and felt angry in his heart.

I think it was not easy for him to become a teacher, so he finally got some hints, came to Yanjin in advance, prepared to rest and recharge his energy for the next journey, but someone wanted to find something to delay him.

This makes him very unhappy.

"So what if you do it, kid, apologize, or today you..."

With the sword drawn out, this kid is still looking at him with that kind of disdainful eyes, it really makes people want to beat him up!

"Don't let me go today, you even want to beat me up." Tian Yu held the gun tightly with his right hand, and veins began to swell on the back of his white hand.

"It's good to know." The man with the sword smiled proudly.

But his smile didn't last for a second or two, and then Tian Yu turned his hand slightly, and the iron gun hit his sword.

With a sound of 'ding', the long sword swung out, and the body of the person holding the sword leaned slightly.

Suddenly, there were several laughs from all around.

I don't know if the target of this laughter is him or Tian Yu.
