The little eunuch took a quick and anxious step in front of him, and he led Liu Yu to a relatively quiet road. It was already night and the lights were on, and there were fewer and fewer lanterns on the way, which made Liu Yu feel alert. Could it be that Wu You wanted to kill people in the dark and windy months or beat up to vent his personal anger?

"Young Master Liu, the national master is waiting inside, please come in. The villain has surrendered."

The little eunuch took Liu Yu to a dark palace. The whole palace was full of momentum, but there was only a lantern swaying in the wind hanging above his head.

"He's inside?"

The door was open, and Liu Yu leaned his head in, and felt like he was unable to see his five fingers. Turning around, the little eunuch had already slipped away.

Be careful.

Liu Yu touched the door and held the door latch more than three feet long in his hand. If there was a sudden attack, there would be a good guy. He walked in with the darkness for a while, and his eyes gradually adapted to the darkness. He walked around the front hall and went to the back hall. It also seemed a little lit inside. Wu You was fiddling with something in front of the table, and there was only a very dark candle beside him, so he couldn't even illuminate half of the room.

Hearing the footsteps, Wu You raised his head and frowned when he saw Liu Yu holding the door bolt in his hand.

"What are you doing?" Wu You said with a brow.

"I should be asking you what you are doing. I asked me to apologize to your great-granddaughter. Why did I take it to such a deserted place like a charity village?" Liu Yu was not sure if there was an ambush around, and the door bolt was still not leaving.

"This is the place where the old man usually refines elixirs. Where can he go if he doesn't come here?"

Wu You finished speaking unhappily and continued to lower his head and tinker with what seemed like a wooden board in front of him.

The room was very quiet. Liu Yu stood with a door latch and felt bored. He put the door latch down and looked around. It was a very messy hall, with bookshelf, tables, chairs, and many messy things. He raised his head and found that there were actually a few tiles missing on Wu You's head, and you could see the sky directly.

"Hey." Liu Yu pointed to the leaking tiles and said, "The roof seems to be broken, aren't you afraid of... it will rain and leak?"

Wu You didn't look up and pointed to the basin on the ground and said, "It's sunny tonight. Even if it rains and leaks, there will be basin afterwards."

Liu Yu really couldn't figure out the old man's temperament. Could it be that the roof of the palace in the palace was leaking and no one came to repair it? Or was the old man afraid of being suffocated and needed to make a hole in the roof?

"You hand over those boards."

As soon as Liu Yu sat on the chair, Wu You said as if he was a servant. There were indeed a few wooden boards on the small square table in front of Liu Yu. "These?" Seeing Wu You nodding, Liu Yu didn't go and handed it over, and threw it over directly.

"Where is your great granddaughter? Didn't you ask me to help you? If you want to apologize or perform that trick again, you have to see someone."

Wu You sighed and said, "Since I came to the palace, Xiao Ya's heart has become wild. She has been running around outside these days. I don't know when I will return, wait."

Liu Yu was so angry that he was so angry that he said: "Didn't your great-granddaughter is so desperate that he refuses to continue learning divination? Now he is just fascinated by the flower world and is making fun of him everywhere. He clearly uses my little tricks that day as an excuse, and this can also be dependent on me?"

After Liu Yu finished speaking, he couldn't help but think that Wu Shuo's expression and behavior that day did not seem to be pretending, which means that he still hurt the girl.

"You know it yourself!" Wu You seemed to be able to see through Liu Yu's thoughts, but he still didn't look up. "The young man seeks immortality throughout his life, and his life is a lonely person. No man in the family has been married at fifty, got married at fifty, got married at sixteen, gave birth to a grandson at nineteen, and had a white-haired man to send a black-haired man at twenty. This was not until the great-grandson generation that he was happy that Shuoer inherited his mantle."

"Late birth and late childbirth are not enough, it is easy to mutate genes. Wait, you didn't give birth to a son in your fifties, and now you have a great granddaughter. Are you... longevity now?"

"Ninety-two." Wu You replied calmly.

"Ninety-two?" Liu Yu was surprised, "You are at most fifty or sixty years old. Tell me! I don't believe me?"

"Believe it or not." Wu You continued to tinker. "On the day when my grandson-in-law gave birth to Xiao Ya, the old man watched the stars in Long, and the starry sky shone, so he named Xiao Ya Shuo, meaning that it shone like the starlight... Help me hand over the nail."

"Nail?" Liu Yu looked at it, and there was a box of iron nails in a wooden box on the ground. "How do you hand over it? Throw the whole box over to you?"

"You can't send it here? Forget it, you guys are so lazy. You don't need that much. Just wrap a few pieces in paper and throw them over."

Liu Yu did what he said, and Wu You continued to talk nonsense.

"Xiao Ya has been smart since she was a child and learns everything quickly. The little old man is sure that she will inherit my legacy in the future. But Xiao Ya is good at using her left hand rather than her right hand in daily life. For her sake, the little old man corrects her..."

"So she has left her a stuttering problem, right?" Liu Yu said helplessly, "You are an elder. It's great to use your left hand. You have to correct your right hand. This will easily affect her language center and make her speech unsuccessful."

"And so said?" Wu You raised his head in surprise this time.

"That's natural, can't I miss you?" Liu Yuxin said that some things could not be explained clearly to him. After all, he was not a doctor, nor a brain structure. Even if it was true, the ancients could not understand those modern scientific theories. "In short, it's better to use the left hand and not correct the right hand."

However, Liu Yu also understood that it was too late to say it now.

Wu Youxu said: "That's really the fault of the young man, but it was because she was clumsy and focused on studying. Xiao Ya learned to interpret words at the age of seven, and at the age of eight..."

Wu You next talked about her granddaughter's growth experience. Liu Yuke was not interested. He stood up from the chair and turned around the room. He saw a bronze man standing in the corner, with the acupuncture meridians marked very clearly.

"Old man Wu, are you still studying acupuncture?" Liu Yu interrupted Wu You's nagging.

"This place was originally a library in the Imperial Hospital. The old man moved here to watch the stars clearly at night, and some things didn't have time to move them away."

Liu Yu finally understood what the hole on the roof was for. It turned out to be a star-watching person. But then again, there are such a holes that can only be seen in one corner of the star-watching person these days? Isn’t that the same as watching the sky in a well?

Liu Yu walked to Wu You and finally understood what he was fiddling with. It turned out that he was making a simple astronomical telescope. He saw a few uneven lenses fixed to the wooden frame by him, which was similar to the structure of the astronomical telescope.

"Old man Wu, the quality of your glass is not very good." Liu Yu picked up a lens and looked at it. "It is rough and uneven, and there are bubbles inside. Although this is barely considered a convex lens,... it is too inferior to use to build a telescope."

"Oh? Have you seen marbles? It's impossible. Only the royal family has such marbles."

"This is called marble? Oh, we all call it glass. The quality is much better than this. It should be because the manufacturing process is not yet mature."
