Zhang Xinyan glanced at them sharply and said, "Yu Linghan stays, and all their useless things will get out of here." ”

"Yes, Second Old Lady." A group of people bowed to Zhang Xinyan and quickly exited the house.

Such a majestic grandma, Chen Yunuo is the first time in his life to see grandma, grandma has been a gentle and weak character since he can remember, it seems that he knows his family too superficially.

"Grandma, I was careless, please punish me." Yu Linghan knelt in front of Zhang Xinyan and lowered his head and whispered.

"Grandma?" Chen Yunuo looked at his grandmother with a suspicious face and asked.

"Xiao Han, get up, you can't be blamed for this, this world is already sinister, and they haven't found out at all, let alone you." Zhang Xinyan helped Yu Linghan, who was kneeling in front of her, and said.

"Grandma, why does she call you grandma?" In fact, Chen Yunuo didn't want to interrupt their conversation, but he was really curious.

"You kid ......" Zhang Xinyan pointed at Chen Yunuo and said, "When Ling Han was very young, I recognized her as my granddaughter, so she called me grandma like you." ”

"Grandma, you're hiding too deeply, aren't you? I've lived with you for so many years, how come I've never heard you say it. Chen Yunuo couldn't believe that the family members who were facing each other day and night were all big pits.

"There will be more things you haven't heard of in the future, just get used to it." Zhang Xinyan understated.

Chen Yunuo's character is that you don't say that I ask, "What is the Apocalypse Stone?" You've got to tell me about that! Yu Linghan mentioned it on the train before, and those thieves asked me to take it just now, and I almost took my life, this grandma can't fool me. He looked at his grandmother with a firm look in his eyes and said.

"If you really put your life on the line, you are also not good at learning. Okay, I'll tell you everything when it's dawn, and now you go to the guest room to clean up and let Xiaohan rest. Zhang Xinyan took the opportunity to send Yu Nuo to say.

Chen Yunuo shook his head helplessly, grandma came again, throwing off the first master of the topic, but he didn't have a problem with her. He glanced at the clock on the wall and then looked at Yu Linghan, it was cold and sleepy in the middle of the night, it was indeed not a good time to talk about things, he had to smile bitterly at his grandmother and went to clean up one of the guest rooms and arrange for her Yu Linghan to live.

"Senior sister, the room is relatively simple, please take a look." Chen Yunuo said politely.

"You call me cold." Yu Linghan said.

"Uh...... Good. "It's really awkward to call a girl who is one year younger than herself senior sister, since she said so, Chen Yunuo also politely accepted it.

Chen Yunuo tidied up everything and left the room and said, "Then I'll go back to the room, you can do it yourself." ”

"Hmm." Yu Linghan responded in a low voice.

I heard that Yu Linghan has a superior family since she was a child, and she lives in a small house like theirs, I don't know if she can sleep? Oops, ignore it, I still have a lot of troubles, whether she falls asleep or not, she is the one who wants to sleep quickly, and there are still many questions to ask grandma tomorrow.

Early in the morning, a ray of sunlight shone into the window, and the warm sunlight shone on Chen Yunuo's handsome face, he stretched his waist, the sky finally dawned, there were too many things in his head this night, and he couldn't sleep well if he didn't figure things out, when he lifted the quilt and was about to get up, a gust of cold wind made him shiver, and he rolled into the quilt again, it was too cold, or nest in bed for a while, do a few warm-up exercises and get up again.

After exercising, the whole person was hot, Chen Yunuo hurriedly washed up and prepared to make breakfast in the kitchen to please grandma.

He opened the door, and there was a smell outside, and he saw that the table was full of hot breakfast, with porridge, buns, fritters, and dumplings......

Chen Yunuo sat down next to his grandmother and said, "Grandma, you got up so early, why don't you sleep for a while?" ”

Zhang Xinyan ignored him, she looked in the direction of the kitchen worriedly and shouted, "Xiaohan, come out and eat quickly, otherwise breakfast will be cold later." ”

"You eat first, I'm almost ready." Yu Linghan replied.

Chen Yunuo looked at the table full of breakfast, and then asked his grandmother, "She made this?" ”

Grandma smiled bitterly and said, "It's all takeout, but she called it too early, and everything was cold, so she got it hot inside." ”

Crackling, a crisp sound came from the kitchen, and Chen Yunuo instinctively reacted quickly and ran to the kitchen to see what was going on. When he entered the kitchen, he saw several smashed dishes on the ground, so that he could imagine the embarrassment of Yu Linghan hot dishes in the kitchen just now.

"You go out to eat first, let me get it here." Chen Yunuo stretched out his hand to hold the broom in Yu Linghan's hand and said.

"Okay." Yu Linghan lowered his head embarrassedly and replied softly.

After witnessing her go out, Chen Yunuo took a closer look at the kitchen, in addition to a few broken dishes on the ground, there were also a few paste-like dumplings in the pot, which should have fallen when steaming the dumplings just now, and there was an oil stain next to the gas stove, and the oil bottle should have been broken, he took a deep breath and simply cleaned up the mess.

After Chen Yunuo cleaned up, he returned to his position on the dining table, he picked up a bun and asked while nibbling, "Grandma, what is the Revelation Stone?" Have I seen it? ”

"The Apocalypse Stone is a treasure that we have passed down from our ancestors, so there are many people who covet it, but not everyone is qualified to own it, because it will choose its own owner to wear it." Grandma put down the chopsticks in her hand and said with a long sigh.

"The stone will also choose the master so powerful? How to choose? Hearing what grandma said, Chen Yunuo became even more curious.

"When you return to your home, they will tell you, and now the most important thing for you is to find this revelation stone, I don't know where your father hid back then." Zhang Xinyan said.

Grandma's technique of changing the topic is always so clever, every time Chen Yunuo can only follow the topic behind her, "Even you don't know, where can I find it?" ”

"For such an important thing, your dad will definitely leave a clue for us, you go to your dad's room to find it." With Zhang Xinyan and Yinan getting along for all those years, she can say it with certainty.

Although grandma is dizzy, her head is very clear and easy to use, Chen Yunuo hurriedly ate two bites of steamed buns and ran to her father's room to rummage. He and Yu Linghan searched for a long time, repeating it many times, but they didn't turn the whole house upside down, it was full of ordinary things, and there were no records and clues about the Apocalypse Stone at all.

"Grandma, will my father take the Apocalypse Stone away with me?" Chen Yunuo squatted at the door of his father's room, turned his head to look at his grandmother who was drinking tea in the hall, and asked.

"Your dad won't take it, he should hide the Revelation Stone in a safe place." Zhang Xinyan said with certainty.

The clue is not in Dad's room, is it in Brother's room? Chen Yunuo thought for a while, then got up and walked to the eldest brother's room.

"It's not in your brother's room, let's go look for it in your room." Zhang Xinyan shouted when she saw this.

Chen Yunuo turned his head to look at his grandmother in surprise, "Grandma, are you kidding, can I know if there is anything in my room?" ”

"Don't be poor, go find it." Zhang Xinyan urged.

Chen Yunuo reluctantly muttered while flipping through, "In addition to the furniture in the room, there are some books and gadgets I bought, what clues are there, my father left without even saying hello to me, only leaving ...... A letter. ”

"Yes, Dad left him a letter." Chen Yunuo immediately took out the letter locked in the drawer and looked at it carefully, he and his grandmother flipped the letter around, read it again and again, and the content of the letter was nothing special, I thought there would be clues, it seems that they will continue to look for it.

"Chen Yunuo, there seem to be some words in your envelope bag." Yu Linghan, who was observing the subtleties, pointed to the envelope bag on the table and said.

Hearing what she said, Chen Yunuo picked up the envelope and looked at it carefully, and found that there were indeed some words printed inside. He carefully opened the envelope, which was a rectangular piece of paper, and one of the pages of the envelope was filled with a bunch of irregular numbers, spaces, and a few spaces with circles and X's drawn in them. At first, he thought that these numbers were the design pattern of the envelope itself, but now that he looked carefully, he realized that these irregular numbers seemed to have a certain pattern.

"This should be the clue that my dad left me. Thank you, Han. Chen Yunuo stared at the envelope and said to Yu Linghan.

"Hmm." Yu Linghan replied briefly.

"Do you know what's in it?" Zhang Xinyan asked impatiently.

"What do these numbers represent? I can't say for sure, but if we get out of the numbers, we'll know if it's a useful clue. Chen Yunuo briefly explained to his grandmother.

He went back to his room, picked up his pen, and substituted the numbers into many mathematical formulas, but the results did not match. When he was dizzy, he went to his father's room to find inspiration, and his father's room was pacing back and forth, unconsciously talking to himself, "I should be able to make the things I like and are best at into codes, good at, good at...... Daddy is what he does best. ”

There are three large bookcases in Dad's room, Chen Yunuo walked to the bookcase to carefully check what books Dad bought, the books in the bookcase cover a wide range of fields, there are many maps, attractions, design, astronomy and so on. He continued to rummage through the other two cabinets, the second of which was a collection of books on archaeology, ancient texts, and antiques, while the third bookcase contained a lot of books on mathematics, physics, and numbers. He rummaged through a lot of books and the numbers in the envelope, but found that there was a Sudoku book and the format of the envelope, the arrangement of the numbers is very imaginary, they are all nine horizontal and nine grids, but the number arrangement in it is different, he has to fill in the blank numbers in the envelope according to the operation method of this book, and what do the circles and X represent? I don't know where to point yet, but these should be clues left by my father.
