Wei Yan had no choice but to let go of Huang Yueying, and said guiltily: "Madam, I originally wanted to reward you for my husband, but now I'm afraid it's going to be delayed!" ”

Huang Yueying's big blue eyes showed a curious look: "Husband, what reward?" ”

Wei Yan smiled: "Haven't you always been curious about why the sunlight is colorful, I want to make a prism for you." Pen & Fun & Pavilion www.biquge.info"

"It's not in a hurry, it's not too late to do it when you come back from the expedition," Huang Yueying said with a smile: "Husband, the concubine body remembers, the telescope you mentioned to the concubine body before, we have done it!" ”

Wei Yan was overjoyed: "Really? Great, show it to me! ”

Huang Yueying took out a box from the cabinet, took out a bamboo tube from the box, and handed it to Wei Yan: "Husband, take a look." ”

Wei Yan picked it up and saw that it was a telescope formed by two polished crystals inlaid in a bamboo tube, and they were monocular.

He put the crystal telescope in front of his eyes and looked ahead, and then couldn't help but shake his head.

Huang Yueying hurriedly asked, "Husband, what's wrong?" ”

Wei Yan said seriously: "First of all, the light transmittance of the crystal is not good, and secondly, the cost of the crystal is expensive......

Huang Yueying smiled bitterly: "But we can't find anything more translucent than crystal." ”

Wei Yan then remembered that he had been busy fighting and training these days, and had not yet started refining glass.

He hurriedly took out a piece of paper from his body and handed it to Huang Yueying: "You ask Ma Jun to copy another copy of this paper, and you two workshops will compete again to see which workshop is the first to make the glass with the best light transmittance, yes, it is called glass, which is transparent and colorless, not glass." The war situation was urgent, so I left first. ”

"Wait a minute," Huang Yueying pulled Wei Yan and said, "Does the husband have any plans for how to defeat the 60,000 Yuan army?" ”

Wei Yan shook his head: "The specific situation has not yet been figured out, and it is still uncertain." ”

Huang Yueying's big blue eyes showed a wise light: "Husband, the reinforcements are coming from Huainan, and they will definitely cross the Huai River to attack our army, and the key to victory or defeat is the Huai River!" Now in August, the mountain rain is coming. ”

At this moment, the stunt [husband and wife concentric] shared by Wei Yan and Huang Yueying is playing a role, and the intelligence and politics of the two of them are temporarily increased by 5 points, Wei Yan instantly understood what Huang Yueying meant, laughed, and kissed Huang Yueying's cherry lips: "My good lady!" You're so smart! ”

Then, Huang Yueying opened a mechanism, the door of the secret room opened, and the two went out of the secret room.

Wei Yan looked at Huang Yueying with appreciation: "Madame is so capable, this secret room is too mysterious, the people inside can see and hear the people outside, but the people outside can't see the people inside, and they can't hear the people inside, it's wonderful." ”

Huang Yueyingjiao smiled: "In fact, it is the wisdom accumulated by hundreds of years of predecessors, not what I thought. ”

After leaving the secret room, Wei Yan and Huang Yueying no longer mentioned the word Mo family, and after that, they talked about it outside, and they all used the word Lu Ban to replace Mo Zhai or Mo family.

In fact, the Mohists were able to survive from 400 BC to 1600 AD for two thousand years, relying on that method to deceive the descendants of Luban and mix in the majority of craftsmen.

Returning to the Pingnan General's Mansion and arriving at the council hall, the generals in Pingyang New Town received a notice and came to discuss the matter and prepared to deal with the invasion of Yuan's army.

If you put aside the combat strength, the number of troops sent by Yuan Jun this time is the largest after Wei Yancheng became an army, so everyone's expressions are very solemn.

There were only two people at the scene with relaxed expressions, one was Xu Shu, and the other was Wei Yan.

Dong Ju looked at Wei Yan with a relaxed face, and hurriedly arched his hand and said: "Lord, the Yuan army has come this time with an army of 60,000, not an army of 6,000, please don't underestimate the enemy." ”

Xu Shu laughed loudly: "Yuan Shu's way of using soldiers, just like the Yellow Turban thief, likes to coerce the people the most, bravado, bluff, not to mention whether Zhang Xun, Lei Bo, and Chen Lan have 60,000 horses, even if there are, the elite soldiers are probably about 6,000, less than 10,000, after all, now Liu Bei has been hit by the plan to drive the tiger and devour the wolf, and raise troops to fight against Yuan Shu, Yuan Shu must use the main force to fight Liu Bei, where are the troops used in Runan!" You don't have to worry, you don't need to be recruited by the lord himself, you only need to send a general with 5,000 men to support Wen Ping and Gan Ning to break the Yuan army! ”

Wei Yan nodded: "Yuan's straightforward words are reasonable, this time I don't need to recruit in person, I will ......" He looked around at the generals,

Xu Huang, Yu Ban, Guan Hai, Wen Yang, including Li Yan, Man Chong, and Dong Ju all took the initiative to ask for help.

Wei Yan originally intended to go to the ban, there were many mountains and forests in the upper reaches of the Huaishui, the cavalry could not gallop, Xu Huang had no place to use, and the infantry led by Yu Ban was more suitable, but Wei Yan remembered that the loss of Yu Ban's fame and fame was related to water, and he was a little drumming in his heart.

Just as Wei Yan was about to go to Guan Hai, Wei Yu hurriedly walked in and whispered a few words in Wei Yan's ear.

Wei Yan pondered for a moment, suddenly changed his mind, and said loudly: "This time I want to conquer in person, not only in person, but also in person, and lead 20,000 horses to conquer in person, I will not only defeat Zhang Xun, Lei Bo, and Chen Lan, but I will also attack Shouchun and teach Yuan Shu Lao'er a lesson!" ”

The generals were all stunned, the lord's mind changed too quickly, what did Wei Yu say to the lord just now, how could it have such a big impact?

Wei Yan dispersed all the maids and guards in the council hall, and then said to the generals, "I just received an accurate piece of information...... According to this information, we are facing a rare opportunity, and this opportunity must be seized, so this time I must 'personally recruit'! ”

Only then did the generals understand, and their faces all showed excited expressions, and they all felt that the lord was really playing a big game!

Wei Yan ordered the generals: "Wen Ze and Berning will go with me on the expedition, and other generals will make other arrangements." ”

The next day, 20,000 horses set off from Yiyang New Town, mighty and mighty, killing and going to Huainan, Wei Yan was in it, black black horses, red blood knives, very conspicuous.

Several of the onlookers in Yiyang saw this scene, and they were all overjoyed.

……

Two days later, the information sent by the horse arrived at Cao Cao's desk.

Cao Cao shouted: "Wei Yan's soldiers sent to Huainan, it is a God-given opportunity for me to use troops in Nanyang!" ”

The generals agreed.

Cao Hong said in a sullen voice: "Lord, why don't you send troops to Yiyang and take down Wei Yan'er's lair?" ”

Cao Cao shook his head: "I have seen the sketch of Yiyang New Town, the degree of easy defense and difficult attack is even greater than that of Luoyang, Wei Yan only needs to leave 5,000 men and horses, he can hold it for half a year, and Juan'er and Juan Er are in Yiyang New Town, eager to do it, I am afraid that their lives are in danger." ”

Guo Jia said with a smile on the side: "Wei Yan is a rebellious wolf, the wolf looks back and eats Liu Biao, and the benefits of keeping it outweigh the disadvantages for us, why not keep it to curb Liu Biao?" Zhang Xiu is the dog of the household, take it, take the land of Nanyang, and you can clamp Wei Yan and Liu Biao......"
