It is very different from Jiangdong's trembling up and down, Guo Jiade Pang Shanmin borrowed money, silk, grain, and straw, and after entering the Xu capital, among the prime ministers, a group of Cao Ying's strategists and Cao Cao himself were anxious

Although Guo Jia's contribution is not small, and the price paid by the Central Plains in the future is far from being high, Guo Jia's many calculations in Jingxiang have been wasted, which has to make Cao Cao and others feel more and more heavy.

If it is said that Pang Shanmin's behavior was more like a businessman before, and he could be tempted, but now his behavior is more calm, Guo Jia used Jiangdong as bait, but he couldn't do all the work, which obviously shows that this Pang Shanmin is much more mature in doing the things of princes.

Cao Cao's face was gloomy, and after Guo Jia's report, he sighed lightly and said: "The matter has come to this point, you should take Qingzhou first, and the rest of the trivial matters, let's wait until this Jiangdong disaster is gone, and then discuss!" ”

Now it has been three years with Jing Xiang to strike the war, but Runan, Chang'an direction, are heavily armed, although Cao Cao believes that Pang Shanmin can do what he says, but he has to secretly beware of the two places, after the battle of Runan, Cao Cao has been calculated by Pang Shanmin, now not only need to strictly prevent Jingxiang's army from committing borders, but even to check and fill in the gaps, so as not to be raised by the Pang Shanmin in the future.

In addition to this, the Qingzhou war will be warm in the spring of the next year, and the matter of moving the capital is also imminent, and Cao Cao felt tired and lacking skills for a while.

However, these many things must be solved, and the Jiangdong army and horses are driven away from Qingzhou, which is the thing that Cao Cao cares about the most, Zhou Yu does not leave, Cao Cao is uneasy, and the Qingzhou army has made Xuzhou and Yangzhou two places, and the rumors are loud.

Jiangdong's ambition is not small, although Cao Cao is not afraid. But it is difficult for the people to see through the current situation, and now many people in Xuzhou and Yangzhou have moved their families to the hinterland of the Central Plains to avoid disasters in Yanzhou, Jizhou and other places. It's not what Cao Cao wants to see.

Cao Cao said that the ministers had no objections, and the matter of taking Qingzhou was imminent. With Zhou Yu's ability, even Guo Jia and others did not dare to give him a chance to operate in Qingzhou for a long time. Once the people of Qingzhou are stable, the Jiangdong army and horses will accumulate more, and the price will be too great if they want to take it.

When the three-legged stand today, no matter which princes, they are unwilling to start a war lightly, and the relationship between these three princes is complicated, if it is not for Qingzhou to take it, Cao Cao will not even care about what Sun Quan has done this time.

Now except for the mountain people of Napang. It is difficult to find any prince who is not in a state of war, and even a chance to recuperate.

The first snow in Jingxiang, the snow is clear.

Pang Shanmin rarely had time to go to the academy. I wanted to go to see my father at home, but when I arrived at the academy, I saw that Huang Chengyan was not in the workshop pondering thaumaturgy, but was talking to Pang Degong about the inventions and creations of recent times.

Just looking at the appearance of Pang Degong brushing his beard again and again, he knew that the two of them were chatting quite deed.

After Pang Shanmin entered the house. bowed and smiled at the two: "Meet my father, meet my teacher......"

Seeing the arrival of Pang Shanmin, Pang Degong bowed his head slightly, and said to Pang Shanmin: "Gongyan who came this time, what kind of talents does the old man have, and he is in the eyes of the mountain people?" ”

Jiang Wan has been promoted by Pang Shanmin repeatedly because of his conscientious work in governing Changsha, and this person cherishes his talents, recommends many outstanding students of the academy, and enters Jingxiang as an official.

Hearing this, Pang Shanmin shook his head slightly, and was about to speak, but saw Huang Chengyan smile and said: "After a while, the water mirror is also coming, since the mountain people are here, you might as well talk to us old guys!" ”

"Father and the two teachers have something important to discuss?"

Pang Shanmin was puzzled, nodded, and said to Pang De: "The three of them are discussing in the same place, I'm afraid it's not a small matter!" ”

Pang Degong smiled when he heard this: "It's all Cheng Yangong's whimsical ideas, called Decao Tongzhi, just want to ask him if this new strange thing can be used in military affairs!" You also know that your father's affairs in the military family are far inferior to your moral teacher. ”…,

"I see!" Pang Shanmin couldn't help but laugh when he heard this: "Please also tell the teacher what it is that can make the three elders pay so much attention!" ”

Huang Chengyan smiled when he heard this: "It's not a strange thing, it's just that the old man passed by the riverside by accident before, and saw a forest of beacon towers on the riverbank, and he had a whim......

After that, Huang Chengyan spread out the package on his case, and after opening it, Pang Shanmin couldn't help but be stunned, there was nothing else in the package except for some colored soil.

At this time, Pang Shanmin heard a sound outside the door, and knew that Sima Huizhi was there, so he hurriedly got up and turned around, bowed and said, "The student has seen the teacher." ”

"The mountain people are here too?" Seeing this, Sima Hui put away the smile on his face and said to Huang Chengyan: "Chengyan, have you informed the mountain people about this new five-color beacon smoke?" ”

Huang Chengyan shook his head when he heard this, and said: "The mountain people are just at the right time, and this thing has yet to be verified, so call Decao, so it's a matter of fact!" ”

Sima Hui nodded when he heard this, but Pang Shanmin looked puzzled and said, "What five-colored beacon smoke?" ”

Huang Chengyan said with a smile: "Before, the old man was thinking, this army is conquest, the transmission of messages is inconvenient, passing by the riverside beacon fire, whimsical idea, if the war does not use letters to transmit military information everywhere, but instead use beacon smoke to transmit news, will it be much faster!" ”

"Five-colored beacon smoke, combined with each other, can express a simple military situation?" Pang Shanmin said, Huang Chengyan couldn't help but be stunned, and then smiled: "That's right! The mountain people are perceptive, and it's really good! ”

"If it is a simple military situation, it can be conveyed with beacon smoke, but it can also be done......" Sima Hui smiled slightly when he heard this, and then said solemnly: "It's just to avoid the enemy army from knowing in detail, the content expressed by this beacon smoke, and this thing has great requirements for this weather!" It's fine on a sunny day, but once it rains on a cloudy day, this thing is useless! ”

Sima Hui said, Huang Chengyan also nodded, frowning and thinking about the value of this five-color beacon smoke, whether it is worth vigorously promoting, but Pang Shanmin was happy and imaginative.

The exchange of information in this era really makes Pang Shanmin unbearable, that is, the military situation in various places, the quick and urgent report, the time consumed is also expensive, if it is good news, once it encounters an emergency military situation, it will have a great impact on the victory or defeat of the war.

If you can use beacon smoke to transmit information, it is indeed much faster than war horses, but ordinary beacon smoke can only inform the beacon fire in various places whether it is "safe" or "not safe", and it is impossible to accurately understand the number of enemy troops and the battle situation......

The combination of five colors is enough, and for the soldiers of the beacon towers everywhere, when the beacon fire is fired, they only need to know the meaning of each color and light it.

Moreover, Pang Shanmin's thoughts are far more than that.

Seeing that Pang Shanmin was in thought, Sima Hui couldn't help but smile and said, "Chengyan, it's really your student!" This distraction kung fu is out of the blue! ”

Hearing Sima Hui's ridicule, Huang Chengyan didn't argue, just looked at Pang Shanmin with a look of hope, before Pang Shanmin saw through the use of this five-color beacon fire at a glance, and now he is in a reverie, maybe he has any new ideas.

In Huang Chengyan's eyes, Pang Shanmin, a traverser, is a thaumaturge, and his understanding is terrifying!

After a long while, Pang Shanmin came back to his senses and smiled awkwardly: "I ask for your forgiveness for neglecting all the teachers!" ”

"Speak up if you have something to say!" Huang Chengyan couldn't wait to say to Pang Shanmin: "Let's talk about the mountain people, if the old man's 'five-colored beacon smoke' is applied to the army, the role is as Decao said, so useless?" ”

"Naturally not!"

Pang Shanmin said, but saw Sima Hui say to Pang De: "See, this is how the teacher is out of the same family!" What's the use of your beacon fire, which is just an ordinary color, only a lot of colors? ”…,

Pang Shanmin didn't say much to Sima Hui, but walked to the package, took out a few beacon dyes, and said to Sima Hui: "Beacon fires of different colors can represent the number of enemy troops, and the enemy army with less than 100 people can be ignored...... As for if it is more than 100,000, it will not be a surprise attack at all, and the soldiers and horses will move, and I Jingxiang will already know about it! ”

Sima Hui nodded when he heard this, and said: "This is feasible, and in the future, we can let this beacon fire be promoted in the army and prevent the enemy!" ”

Huang Chengyan saw that Pang Shanmin had persuaded Sima Hui, and naturally looked happy, no one wanted their own inventions and creations, just a pile of waste products.

However, Pang Shanmin shook his head at Sima Hui with a solemn face and said: "Mr. Decao, the purpose of this five-color beacon fire is far from being so narrow in the eyes of Pang Mou!" ”

Seeing that the three division commanders were all stunned, Pang Shanmin laughed loudly: "Pang Mou personally conquered Xichuan and Yongliang before, and now he deeply feels that after the army is launched, the news transmission of various military horses is extremely slow. ”

"Your army is pulling out, and you are still carrying the beacon tower to do ......" Sima Hui said, suddenly stopped silent, and then said to Pang Shanmin with a happy face: "You mean, use beacon smoke instead of scouts?" ”

"In rainy weather, naturally there is no need for this beacon smoke, but when the two armies are fighting, who will choose the stormy weather?" Pang Shanmin smiled when he heard this: "And the beacon smoke is fast to deliver news, faster than the fast horses in the army, several times faster, if this thing is used well!" My army is conquering, and we can take the lead! ”

"How can it still work?" Even Huang Chengyan, the creator of the five-color beacon smoke, didn't expect Pang Shanmin to expand the use of beacon smoke to such a point, Huang Chengyan was overjoyed, and smiled at Sima Hui: "Decao, what else do you have to say now?" ”

Sima Hui couldn't help but smile bitterly when he heard this, and said to Huang Chengyan: "You old guy probably didn't expect that the newly made beacon smoke would have such an effect!" But then again, looking at the mountain people now, Bo Yan is blue, but the old man thinks that we are really a little old! ”
