The night is getting darker, and the moon is like water outside the window.

He should have gone to bed early, but Zhaoyun was neatly dressed and stood by the window, looking at the bamboo forest outside the window.

Outside the cupboard, Ming Cui's even breathing sounded from time to time.

Suddenly, the wind whistled into the house. Zhaoyun felt quite cold and was about to close the window tightly, but saw a black shadow flash in front of him.

Looking back, Su Zidui was wearing a night suit and standing in front of her coldly.

Zhaoyun shuddered in fright, and was inadvertently taking a step back, but was suppressed by an unfamiliar force.

She felt a tightness in her waist, and when she looked down, she saw a pair of bony hands resting on her thin waist. A burst of warmth instantly passed through the light clothes, and Zhaoyun froze instantly.

"You! Why? Zhaoyun raised his head and was about to scold, but he didn't expect to look into a pair of eyes.

Although there was a hint of a smile in his eyes, when he looked closely, there was still a hint of coldness. There seems to be a vast ocean inside, dark and turbulent, bottomless.

Su Zidui withdrew the hand that was on her waist, withdrew the only trace of smile that remained, and said casually.

"It's just that I'm afraid that you will be frightened and retreat, and knock down the vase placed behind you, so as to delay our big business, princess, you don't have to be grateful to me."

In an instant, a flock of crows flew over Zhaoyun's head. She didn't want to deal with this brazen person, looked at him, and said coldly.

"I've been inquiring for the past two days, and the letter you're looking for is probably not in Luo Ye's bedroom. I suspect that it may be hidden in the Imperial Study. ”

Su Ziwan raised her eyebrows, noncommittal or not.

Immediately, the two walked into the boundless darkness. The night is the best barrier. Zhaoyun felt that Su Zidui, who was dressed in black, had already blended into the night.

She walked beside him, but only to his shoulder. Su Zidui walked quite fast, and seeing that Zhaoyun could barely keep up with him, he slowed down.

She suddenly had the illusion that they were not stealing, but wandering around.

At this time, above their heads, the dark clouds that obscured the moon gradually dissipated, and the moonlight slanted down. The ground was instantly empty like stagnant water, and there seemed to be algae in the water. Zhaoyun looked closely, but it was just the shadow of bamboo and cypress on both sides of the road.

By the moonlight, Zhaoyun looked at Su Zidui, who was walking in front. His shoulders were wide and his waist was narrow, and his night clothes were so obedient to him, Zhaoyun sighed unconsciously.

Just as he was thinking, the person walking in front suddenly stopped and turned around. Zhao Yun didn't have time to stop, and slammed into his chest.

"Why didn't you leave all of a sudden?" Zhaoyun touched the tip of his nose that was hit red, and said dissatisfied.

Unexpectedly, the initiator in front of him had no guilt, and asked without answering with an expressionless face.

"Don't you look at the road when you walk? Don't even know if I stopped? ”

Zhaoyun twisted his head to the side, didn't answer his words, and walked straight ahead.

She thought to herself: Who can have such a good resilience and can stop immediately? He's really arrogant and unreasonable! If it weren't for him, I wouldn't have dealt with this kind of person.

Su Zidui followed closely, looking at her angry back, and felt a little like laughing.

The sound of insects chirping spread behind the two.

They then came to a flower bush not far in front of the Imperial Study. Seeing a guard in silver armor standing in front of him, Zhaoyun immediately squatted down and hid his figure through the thick branches. looked back, but didn't see Su Zidui's figure.

Looking around, he found himself standing on a large tree with lush foliage. If you don't look closely, you wouldn't have thought that there was a person standing here.

How did he get there? Zhaoyun was quite puzzled in his heart.

Looking at the guard in front of the imperial study, I saw him standing upright, immovable. Holding the spear of the pestle in his hand, he stared straight ahead, his eyes blazing.

Zhaoyun beckoned to Su Zidui in the distance, and in the blink of an eye, he came behind Zhaoyun.

"You see that man has been staying here, how are we going to get in?" Zhaoyun looked at him behind him and asked.

He took out a brown projectile from his cuff and threw it at the guard with precision. As soon as the projectile hit the ground, it immediately volatilized into a puff of white smoke.

In the thick white smoke, the guard immediately fainted to the ground. The heavy spear was about to fall to the ground, but Su Zidui dodged, then caught it and placed it beside the guard.

Zhaoyun poked his head out from behind the flowers, and he was amazed, this person really seemed to be able to fly. From the moment the projectile landed to the time the guard fainted, it was just a snap of a finger.

"Your light skills are really amazing." Zhaoyun trotted over, unconsciously sighing.

Su Ziwan raised her eyebrows, noncommittal or not. Then he took out a thick needle with a thin tip from his bosom. I saw him poke a few times on the big bronze lock hanging on the door of the imperial study, and then he heard a click, and the lock was warped open. Turning around, he pushed open the hollow lacquered mahogany door of the imperial study and walked in. Zhaoyun followed, reaching out and closing the door.

"Don't mess with the furnishings of the imperial study, Luo Ye is an extremely careful person, and his things are not placed casually." Zhaoyun reminded in a whisper.

Su Zidui nodded, took out a fire fold from his arms, and with a pop, the faint light instantly sprinkled the entire imperial study.

In the dim light, I saw a half-person-high table on the left, on which the yellow background was neatly stacked. There are also several folds spread out and placed aside, and an inkstone with black ink rests on the side.

On the right-hand side is a gold-wire wooden cabinet against half of the wall, on which are densely packed with books.

"Look for Sun Wu's book on the art of war, that book is not very thick." Zhaoyun walked to the bookshelf to the side and searched for it. Su Zidui walked to her side and silently moved the fire fold to her side.

Zhaoyun saw that his eyes suddenly lit up, and he turned his head to look. I saw that under the reflection of the candle flame, Su Zidu's handsome face looked like a ghost.

Zhaoyun's heart trembled, and she took a small step back, and her back was about to hit the bookshelf, but there was no pain she expected. When I looked back, I realized that it was him who put his hands behind his back.

"You're kind-hearted." Zhaoyun laughed and teased, and for a while he felt that this person was not so bad.

"You're thinking too much, I'm just afraid that you'll bump into the bookshelf and make a noise and attract the patrolling guards." Su Zidui withdrew her hand and hugged it in front of her with one hand.

Well, it's her own passion. How could you think that this person would suddenly have good intentions? Zhaoyun turned his head and rolled his eyes in a direction he couldn't see.

"Don't think I can't see." Su Zi Dujing felt quite funny and reminded him.

Zhaoyun ignored him, fixed his eyes on the bookshelf, and searched carefully.

Finally, on the bookshelf at the top, Zhaoyun found the book. However, she was not big enough to reach it even if she tried to tiptoe.

Su Ziwei couldn't stand it anymore, stepped forward and walked past her, reached out and pulled out the art of war from the bookshelf.

For a while, Zhaoyun only felt that his back was warm, and he suddenly froze in place. The sound of insects outside the imperial study seemed to be far away, and only the sound of each other's heartbeats remained.

Fortunately, he quickly took a step back and looked down at the book "The Art of War". However, behind the root of Zhaoyun's invisible, there was a suspicious redness.

Upon closer inspection, I saw that the book was dark blue, and the side of the book was slightly yellow. The corners of the book are a little curly, indicating that it has been read repeatedly.

Turning the first page, what catches your eye is a sentence written by the fly-headed Xiao Seal: Soldiers, the major affairs of the country, the place of life and death, and the way of survival, must not be overlooked.

This Sun Wu is quite eloquent, longitudinal and far-reaching. Su Zidui sighed unconsciously.

"You turn the page back and see if there's a mark." Zhaoyun reminded in a whisper on the side.

Su Ziwei glanced at her, only to see the dim candlelight reflected on her graceful thin neck, forming a spot of light. He secretly moved the fire fold in his hand.

Sure enough, when I turned to the middle page, I saw a few small words annotated with a brush: anger can be rejoyed, and sorrow can be rejuvenated. The dead cannot be resurrected, and the dead country cannot be restored.

This sentence secretly circulated in Zhaoyun's mouth, and he understood the meaning.

She knew that this annotation was written by her father, and he had already guessed the ending of Yun Qiguo.

Zhaoyun couldn't help but close his eyes, and he only felt wave after wave of fluctuations in his heart, as if there was a black sea, rolling in a turbulent wave. The heart and the darkness are connected, and the ups and downs are slim.

Suddenly, her heart moved, as if she remembered something. He immediately took the book from Su Zidu's hand and turned it to the back of the page.

The black ink seeped through the paper and was printed on the back of the blank. I saw that in the lower right corner of the page, there were seven small characters written "Four years old in the year of Dayan".

Zhaoyun immediately looked at the books placed in the five rows and four columns on the bookshelf. Standing on tiptoe, he took down the book of the Tao from the shelf, turned his head to stare at someone watching the play, and motioned for him to step forward.

Su Zidui shrugged, moved the fire fold to his left hand, and freed his right hand to touch the empty bookcase. Sure enough, in the internal test against the wall of the bookshelf, I felt a bulge and pressed it hard.

The two of them only heard a crunch, as if something had bounced off. When I looked closely, I saw that on the inner wall of the vacant bookshelf, a small opening the size of a palm was opened, and the golden silk wood chips hidden outside fell to the ground.

The two glanced at each other, and both showed a look of surprise in each other's eyes. Su Ziwan couldn't help but snicker, trembling and put his hand into the hole, and then took out a few letters that had already turned yellow.
