While the three of them were talking, Yu Chang kept secretly observing Xi Yunfei.

He is actually very envious of this young man who is a little younger than him. After working in the Ministry of Industry for several years, he has been able to access some confidential information, such as the strategic application of cement and reinforced concrete.

What is even more surprising is the discovery of electricity and the airships that can fly into the sky.

As for electric vehicles, Yu Chang, who has learned about electricity, already knows the general operating principle.

I have to say that Yu Chang is a person who is brave enough to explore. People like him are somewhat useless in the Ministry of Industry, so it is best to be able to go to Shuofang.

Go to Shuofang Library and study at Gewufang. Perhaps it is the best for him.

At this time, when he heard that Xiao Yu was taking a airship to Dingxiang, he looked at Xi Yunfei excitedly.

The scorching gaze made Xi Yunfei's back chill. He turned his head and looked at it, and asked curiously: "Brother Yu, what do you want to say?"

Yu Chang was about to speak, but Yu Shinan suddenly covered his mouth and coughed twice.

He, the father, knows very well about the son's nature.

Yu Chang's face changed and he shook his head at Xi Yunfei in disappointment. He still understood this truth when his parents were there and he was not traveling far away.

Xiao Yu, who witnessed everything, frowned slightly, and he expressed displeasure at the stubbornness of Yu Shinan, his old friend.

He only heard him say, "My friend Xi, I heard that the three generations of children from several aristocratic families, including Cui, Pei, Wang, etc., are all studying in Shuofang... I don't know what they are learning?"

Xiao Yu's words clearly meant to help Yu Chang, and everyone was wise. Although Yu Shinan looked displeased, he was also curious about this issue. So he looked at Xi Yunfei curiously, wanting to know what was going on.

Xi Yunfei was stunned for a moment. He bowed to Xiao Yu first, then glanced at the lost Yu Chang, and smiled and said, "In fact, it's not considered entering school. Generally speaking, they are exploring by themselves. I just told them a principle. To be honest, they are learning by themselves."

"Oh, what do you mean?" Yu Shinan looked puzzled.

Xi Yunfei raised his mouth, picked up the teacup and took a sip. After thinking about the words in his heart, he said, "Tell me, you two may not believe it. When I invented the generator, I just proposed a concept. The people who successfully made the generator were actually Cui Yiye, Changsun Chong and others."

Yu Shinan and Xiao Yu looked at each other, their eyes were full of incredible, and even Yu Chang looked at Xi Yunfei with a look of surprise.

Xi Yunfei nodded slightly with a calm expression and said, "If you don't believe it, you can go to Shuofang to ask someone. There are many people who know about this. The people in the city have talked about it with relish, which made Brother Cui play a big splash in Shuofang!"

Xi Yunfei added in his heart: If you want to talk about which hype is the best, Shuofang Zhiyin finds Liu San.

As early as when Cui Yiye dismantled his bicycle and invented a hand-crank generator, Xi Yunfei asked Uncle Liu San to publish a news article in "Zhiyin" and made Cui Yiye on the list of hundreds of craftsmen and receive a fund reward from Gewufang.

Therefore, in many people's perception, electricity was actually invented by Cui Yiye. As for the electric lights, audio and sightseeing cars that have appeared long ago, they directly ignored it. Anyway, no one knew that the thing was actually electric-driven.

Yu Shinan and Xiao Yu looked at each other skeptically. Xi Yunfei said this very confidently, which made them all believe it. In their subconscious, Xi Yunfei could not have pushed such great contributions to others.

Yu Chang looked inexplicably. He also knew Cui Yiye. He knew how good the other party had. In addition to poetry, songs and essays, he was better than him in other aspects... Speaking of which, his math and physics were even better than him, otherwise the Ministry of Works would not want him!

Yu Chang's doubts were not written on his face, but he could say that he didn't believe Xi Yunfei's explanation in his heart.

After chatting for a while, Xi Yunfei and Xiao Yu made an agreement to set off after tomorrow.

It just so happened that Zhuge Qing was going to Dingxiang, so he asked Xiao Yu to follow him.

Seeing that it was already noon, Xi Yunfei stood up and said goodbye. He originally wanted to visit him for a little while, but he didn't expect that after chatting, half a day passed. He had to go to the Chamber of Commerce in the afternoon, and the power department could not be delayed.

Before leaving the door, Yu Chang jogged forward and said to Yu Shinan: "Dad, you are tired too, so I'd better send Erlang out of the house."

Yu Shinan frowned slightly. Just as he was about to speak, Xi Yunfei smiled and said, "It's good. Master Yu yawned several times. I think he has the habit of lunch break. Let's go and rest now. Just have Brother Yu send me it."

After hearing Xi Yunfei said this, Yu Shinan didn't know what to say. He nodded and let Yu Chang see him off.

Yu Chang looked at Xi Yunfei gratefully and happily led the way.

When the two disappeared from Yu Shinan's sight, Yu Chang hurriedly reached out to hold Xi Yunfei.

"Brother Yu?" Xi Yunfei asked knowingly. He had already seen that Yu Chang had something to worry about.

Yu Chang smiled awkwardly, pointed to the backyard and said, "Erlang is rarely here once, so why don't he go to see his younger sister?"

“…Senior Sister Yu?”

Xi Yunfei was stunned for a while before he remembered it, thought for a while, and said, "If it is convenient, I want to visit it."

Seeing that Xi Yunfei's eyes were still calm, Yu Chang couldn't help but feel a little confused. He heard from his sister that Xi Yunfei secretly gave her a lot of close-fitting clothes. In other words, Xi Yunfei obviously had ideas about his sister. Is it impossible!

Yu Chang calmed down his emotions, changed into a smiling face, took Xi Yunfei to turn left and right in the Yu Mansion, and finally stopped outside a small courtyard surrounded by vines. Widths of faint fragrance came to his face, making people feel relaxed and happy unconsciously.

"Please, Erlang!" Yu Chang stood outside the yard and invited Xi Yunfei.

Xi Yunfei was stunned when he saw this and said curiously: "Brother Yu won't go in with you?"

Yu Chang shook his head and whispered: "I won't go in, so as not to turn around and scold me for being ignorant. Erlang, please ask me. My sister has been waiting for you for a few days. She is looking forward to you every day, and finally I look forward to you."

After saying that, he pushed Xi Yunfei and waited for Xi Yunfei to enter the yard before turning back with a smile.

In the yard, the maid guarding the door saw all this in his eyes. Seeing Xi Yunfei silly hesitating, the maid covered her mouth and smiled, and hurried forward to lead the way...

The layout of the courtyard can be said to be natural. A rockery cut from a few pieces of granite rocks just blocks the view outside the yard. In this way, there is no need to set up a screen wall in the yard. Instead, the rockery is surrounded by green moss, allowing it to blend into the surrounding flowers and plants.

Bypassing the rockery, there is a plank road made of bluestone. The small ponds on both sides are clear and the few colorful koi are not afraid of being alive. When they see someone coming, they even waver their tails and come over.

Xi Yunfei saw a small plate on the handrail of the plank road, and there were a few dried steamed buns in the plate. He picked up one piece, pinched it into the water, and threw it into the water, causing the fish to flutter and the water surface to roar.

At the end of the plank road is a six-sided pavilion.

The pavilion is made of green bamboo. On the eaves, there is a white translucent gauze and satin hanging on each side. The breeze blows by, and the beautiful woman's smiling face is like a fairy in the Moon Palace, and she stunned someone...
