When he returned to his residence, Cao Shuo didn't wait long, and the guards who returned from the blacksmith shop gave him a thin iron sheet.

"How do you happen to have this?" Cao Shuo asked.

"Said it was used to wrap the shield." The guard replied, "The blacksmith came to me, and I brought it back." ”

"Not bad!" Cao Shuo said: "Let them prepare more, and they may use it in large quantities." ”

The guards retreated.

Cao Shuo rolled up the iron sheet and gestured with the water jade again.

"Childe." Attention was on the iron sheet and the water jade, the door was pushed open, and a person jumped in and shouted beside Cao Shuo.

Taken aback, Cao Shuo hurriedly turned his head.

I saw Zhang Chunhua holding his hands behind his shoulders and looking at him with a smile.

"What's the matter, it's scary." Cao Shuo said.

"Yo! Childe also knows what it means to be scary? Zhang Chunhua approached Cao Shuo and looked at what he was fiddling with: "What is this for?" ”

"Binoculars!" Cao Shuo said: "It's very fun. ”

"What for?" Zhang Chunhua blinked twice.

"When I'm done, you'll find out when you try." Cao Shuo said: "Play on the side, don't mess with me here." ”

Zhang Chunhua wrinkled his nose at him.

She didn't leave, but pulled a chair and sat down next to Cao Shuo.

"Why don't you go out and play?" Cao Shuo asked.

"I wonder what Childe has in his head?" Zhang Chunhua said: "It's okay to make these furniture, what kind of telescope do you have to make......

"I'll have a lot of stuff." Cao Shuo raised an eyebrow at her: "Knowing that I am so versatile, can't you wait to sleep?" ”

"Don't!" Zhang Chunhua said: "My sisters have changed their words, I can still call them that, how good." ”

"You're quite a fan of being an outlier." Cao Shuo said: "Next year it should be twelve, right?" ”

"Ten years old this year, eleven next year!" Zhang Chunhua smiled at him: "The year after tomorrow will be eleven ......"

"Why are you so afraid of growing up?" Cao Shuo said: "People have to grow up. ”

"When I grow up, I will be bullied by my son, so I don't want it." Zhang Chunhua said: "It's good to be like this. ”

Reaching out and pinching her little face, Cao Shuo said with a wicked smile: "As the days go by, do you think you can stop growing up by cheating?" ”

"I didn't cheat." Zhang Chunhua said: "If you want to talk about cheating, I'm afraid there are few people who can compare to Gongzi." ”

Cao Shuo's head was full of black lines, and he glared at Zhang Chunhua fiercely.

"Childe, don't stare at me like that, it looks weird and scary." Zhang Chunhua got up and said, "I'm going out to play, not to get in the way of my son's eyes." ”

"I know it's an eyesore, so don't go quickly." Cao Shuo said with a smile.

Grimacing at him, Zhang Chunhua turned around and ran.

It won't take long for Cao Shuo to draw and make things, but if he wants to do it himself, it will take a little longer.

Fortunately, before coming to this era, he had a strong hands-on ability.

It took him more than half an hour to finally make a telescope.

The appearance of the telescope with iron sheet as the cylinder is not very good-looking.

Leaning over his eyes, he saw the door pulled almost right in front of him.

Getting up and coming to the window, Cao Shuo shouted outside: "Chunhua! ”

A crisp answer came from not far away, and Zhang Chunhua ran over.

"Come on, take a look at this!" Cao Shuo handed the telescope to Zhang Chunhua.

Taking the telescope, Zhang Chunhua looked at it over and over again, and asked in surprise: "Isn't this just a tube?" I didn't think it was anything special. ”

"Give it to me!" Cao Shuo reached out to her and asked for her back.

Looking into the distance with his eyes, Cao Shuo said, "It should be seen like this." ”

Taking the telescope again, Zhang Chunhua took a look at Cao Shuo's example.

"Oh my mother!" She was so frightened that she almost threw away her binoculars.

Cao Shuo hurriedly said: "Take it, don't break it." ”

"What the hell is this!" Hurriedly returning the telescope to Cao Shuo, Zhang Chunhua said in shock: "How can you pull things so close." ”

"You look close, but the distance hasn't changed at all." Cao Shuo said: "That's why it's called a telescope." If you look the other way around, what you see is far away. ”

Zhang Chunhua said with some disbelief: "Give me another look." ”

Cao Shuo handed her the telescope again.

With previous experience, Zhang Chunhua took the telescope and looked into the distance.

She watched and grabbed with her hands, but she grabbed it several times but didn't grasp anything.

Standing at the window and watching her movements, Cao Shuo felt funny.

"Childe, can you lend it to me to play with?" Putting down the binoculars, Zhang Chunhua asked Cao Shuo.

"This can't." Cao Shuo said: "I'm still useful at night, and next time I'll let someone do it, and I'll give you another one." ”

Zhang Chunhua stuffed the telescope back to Cao Shuo, turned around and left angrily.

Looking at her back, Cao Shuo was helpless for a while.

Returning to the table with the binoculars, Cao Shuo made some detailed adjustments.

It wasn't until it was dark that he completely finished the construction of the telescope.

"Childe!" Putting down the finished binoculars, Cao Shuo rubbed his somewhat sore eyes, and a maid's voice came from outside the door: "The two ladies and the generals have arrived." ”

"Hold the lamp, let them in." Cao Shuo commanded.

The door opened, and a maid entered the room and lit an oil lamp.

After the maid retreated, Zhao Yun, Chen Dao, Deng Zhan, Zhu Ao, Wang Yan, and Qingwu entered the study one after another.

"It's all here." After everyone saluted, Cao Shuo said, "Sit down and talk!" ”

Everyone sat down, and Cao Shuo asked, "Zhongda and Shiyuan haven't come yet?" ”

"They have some things on their hands, and they should be here later." Chen Zhi replied.

"Then let's talk about the soldiers' drills first." Cao Shuo asked Zhao Yun and Chen Zhi, "How are the Flying Bear Camp and the Dragon Pattern Rider doing?" ”

"Hui Gongzi." Zhao Yun stood up first and said, "The Flying Bear Battalion can go out with Gongzi at any time. ”

Chen Zhi also stood up: "Although the dragon pattern cavalry has not practiced much, the soldiers are already skilled in bowing and horses, and there should be no problem in going into battle to kill the enemy." ”

"I've gone to Fire Dance Camp during the day." Cao Shuo said: "There is nothing wrong with the fire dance, what worries me the most now is the Tuntian army outside the city. ”

"Childe, is there another war?" Deng Zhan asked Cao Shuo.

"Yes, it's going to be a war!" Cao Shuo said: "Unlike fighting Zhang Xiu, this time we have to deal with Lu Bu. ”

"Lu Bu?" Although everyone knew that the Cao family was going to fight Xuzhou sooner or later, they were still stunned for a moment, and Zhao Yun asked, "When will you fight?" ”

"I don't know exactly when." Cao Shuo said: "I have asked Cao Jun to go to Xuzhou, and then to Xiaopei to meet Yang Feng and Han Xian. ”

Everyone was listening to Cao Shuo's speech, and the maid outside the door reported: "Prince Qiyu, General Sima and General Pang and others ask to see." ”

"Invite them in." Cao Shuo commanded.
