Wei Yan had to let go of Huang Yueying and said guiltily: "Madam, I originally wanted to give you a reward for my husband, but now it's probably going to be postponed!"

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

Wei Yan smiled and said, "You are not always curious about why the sunlight is colorful. I want to make you a prism."

"There is no hurry. It's not too late to do it when you come back from the war," Huang Yueying smiled and said, "Husband, I remembered it. We have done the telescope you mentioned to me before!"

Wei Yan was overjoyed: "Really? That's 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, look at it."

Wei Yan picked it up and saw that it was a telescope formed by two pieces of polished crystals embedded in a bamboo tube, and it was a single tube.

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

Huang Yueying asked quickly: "Husband, what's wrong?"

Wei Yan said seriously: "First, the crystal has poor light transmittance, and secondly, the crystal is expensive..."

Huang Yueying smiled bitterly and said, "But we can't find anything brighter than crystal."

Only then did Wei Yan remember that he had been busy with war and training these days, and had not started to refine glass.

He quickly took out a piece of paper from his body and handed it to Huang Yueying: "If you ask Ma Jun to copy this piece of paper, you two will compete with each other to see which workshop is the first to make glass with the best light transmittance. Yes, it is called glass, which is transparent and colorless, not glass. The battle situation is urgent, I will leave first."

"Wait a minute," Huang Yueying pulled Wei Yan and said, "Do you have any plans for how to defeat the 60,000 Yuan Jun?"

Wei Yan shook his head: "I haven't figured out the specific situation yet, and I'm not sure."

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

At this moment, the special stunt [Couple and Wife are in concert] shared by Wei Yan and Huang Yueying is at work, and their intelligence and politics are temporarily improved by 5 points. Wei Yan instantly understood what Huang Yueying meant, laughed out loud, and kissed Huang Yueying's cherry lips: "My good lady! You are so smart!"

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

Wei Yan looked at Huang Yueying with appreciation: "Madam is so capable. This secret room is so mysterious. People inside can see and hear people outside, but people outside cannot see people inside, nor can they hear people inside. It's so wonderful."

Huang Yueying smiled and said, "In fact, it is the wisdom accumulated by hundreds of years of predecessors, not what I thought of."

After leaving the secret room, Wei Yan and Huang Yueying no longer mentioned the word Mo family. After talking outside, they used the word Lu Ban to replace Mozi or Mo family.

In fact, the Mohist school was able to survive from 400 BC to 1600 AD. For two thousand years, it was in such a way that it deceived as the descendant of Lu Ban and mingled among the vast number of craftsmen.

When they returned to the General's Mansion in Pingnan and arrived at the conference hall, the generals in Pingyang New City all received a notice and came to discuss matters and prepared to deal with Yuan Jun's invasion.

If we put aside the combat power, the number of troops sent by Yuan’s army this time was the most that Wei Yan faced after he joined the army, so everyone’s expressions were very serious.

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

Seeing Wei Yan's relaxed look, Dong Jue hurriedly bowed: "Lord, Yuan Jun is coming this time, but it is not a 60,000 army. Please don't underestimate the enemy."

Xu Shu laughed loudly and said, "Yuan Shu's way of using troops is just like the Yellow Turban thief. He likes to carry the people to bravely fight, and bluff the momentum. Not to mention Zhang Xun, Lei Bo, and Chen Lan has 60,000 troops. Even if there are, the elite soldiers are probably about 6,000, less than 10,000. After all, Liu Bei has now been attacked by the plan to drive the tiger and swallow the wolf. He raises troops to attack Yuan Shu. Yuan Shu must use the main force to fight Liu Bei, so how many troops there are still in Runan! You have no worries, you don't need the lord to personally fight, you only need to send a general to support Wenpin, and Gan Ning can defeat the Yuan army!"

Wei Yan nodded: "Yuan said frankly, I don't need to personally fight this time, so..." He looked around the generals,

Xu Huang, Yu Jin, Guan Hai, Wen Yang, Li Yan, Man Chong, and Dong Jue all looked as if they volunteered.

Wei Yan originally wanted Yu Jin to go. Originally, there were many mountains and forests on the upper reaches of the Huai River, and the cavalry could not be galloped. Xu Huang had no place to use his skills. The infantry led by Yu Jin was more suitable, but Wei Yan remembered that Yu Jin's lifetime of fame was related to water, and he felt a little pounding.

Just as Wei Yan was about to call Guan Hai, Wei Yu hurried 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 fight in person. Not only do I have to fight in person, but I also have to fight in person and lead 20,000 troops in person. I not only want to defeat Zhang Xun, Lei Bo, and Chen Lan, but I also want to attack Shouchun and teach Yuan Shu a lesson!"

All the generals were shocked. The lord's idea changed too quickly. What did Wei Yu say to his lord just now? How could it have such a big impact?

Wei Yan dispersed all the maids and guards in the conference hall, and then said to the generals: "I just received an accurate information... Based on this information, we are facing a rare opportunity. We must seize this opportunity, so I must 'in-person expedition' this time!"

Only then did the generals realize that their faces were full of excitement, and they all felt that the lord was playing really big!

Wei Yan called the general: "Wenze, Boning followed me to go to war, and other generals have other arrangements."

The next day, 20,000 people set out from Yiyang New City, rushed to Huainan. Wei Yan was among them, with a black black horse and a red red blood sword, which was very conspicuous.

Several people onlookers in Yiyang were delighted when they saw this scene.

...

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

Cao Cao slapped the case and shouted: "Wei Yan's troops were sent to Huainan, which is a god-given opportunity for me to use troops in Nanyang!"

All the generals agreed.

Cao Hong said in a muffled voice: "Lord, why don't you send troops to Yiyang and take down Wei Yan's child's nest?"

Cao Cao shook his head: "I have seen the sketch of Yiyang New City. It is easier to defend and difficult to attack than Luoyang. Wei Yan only needs to leave five thousand men and can hold on for half a year. Besides, Juan'er is in Yiyang New City. He is eager to do so, and he is afraid that their lives will be in danger."

Guo Jia smiled and said, "Wei Yan is a rebellious wolf. The wolf looks back at Liu Biao. Staying it will do more good than bad things for us. Why not keep it to curb Liu Biao? Zhang Xiu is a dog guarding the household. Take it and take it down and take the land of Nanyang, so that Wei Yan and Liu Biao can be pinned..."
