Su Zidui trembled her hands and flipped through them one by one, as if there was a rope pulling in her heart, faintly painful but a little eager.

These letters are the letters that General Xiao and the former Emperor Chongwen used to exchange back and forth.

In Zhaoyun's impression, General Xiao was once also a powerful and well-known hero. It is said that he once single-handedly broke into an enemy camp and cut off the head of the enemy's leader with a knife in his hand.

It is also said that he once had only 50,000 soldiers and horses, but he defeated 80,000 enemy troops. It can really be described as a bold and strategic character.

It's a pity that such a heroic man finally collaborated with the enemy and treasoned and became a prisoner. The crime of collaborating with the enemy should have been beheaded all over the house. The emperor remembered his meritorious deeds and exiled him to the northern border of Saibei.

Listening to the palace people who did good things, it didn't take long for him to die of illness at the border pass. His wife, who was exiled with him, also hanged herself, but the whereabouts of General Xiao's only son are unknown, and his life and death are unknown.

Zhao Yun was secretly thinking to himself, and Su Zidui on the side was about to unfold the letter inside, when he heard the sound of rustling from not far away. Both of them were stunned and looked at each other in unison.

Su Ziwan hurriedly stuffed the stack of letters into the placket of his clothes, and Zhaoyun hurriedly restored the door of the cave that popped open, and then stuffed the book and the art of war onto the original bookshelf. Everything is back to the way it was.

The candle flame of the fire fold in his hand was blown out by Su Zidu, and the surroundings suddenly became pitch black, only the faint moonlight sneaked into the dark room through the hollow skylight.

Outside the imperial study, a rush of footsteps came into the ears of the two from far and near. In the faint moonlight, Zhaoyun and the others glanced at each other, and immediately moved to hide on the side of the bookshelf.

"Wang Dahua, wake up!" A thin, hoarse male voice came through the door. It wasn't long before another yawn sounded from the other direction.

"Hiss~ Why does the back of my head hurt so much?" Wang Dahua, who was guarding the door, sat up from the ground and shook his head, full of doubts.

"You guy can even fall asleep when you stand, don't stand up quickly, be careful to be seen by Commander Zhao, and remove you!" A shrill voice scolded.

"Huh? How could I fall to the ground and not wake up? Wang Dahua frowned and muttered in a low voice.

"Look, how did the copper lock hanging on the door of the imperial study open?" The tall, thin guard with two mustaches on his chin exclaimed in a hoarse voice.

Wang Dahua, who was sitting on the ground, hurriedly stiffened a carp and looked at the imperial study anxiously. Sure enough, the bronze lock, which should have been firmly locked, was hanging on the door in disguise. He chuckled in his heart, and his legs suddenly softened.

The two looked at each other, and both saw panic in each other's eyes. Wang Dahua moved his right hand to the handle hanging from his waist, and slowly clenched it, ready to pull the saber out of the leather scabbard hanging from his waist.

At this moment, the moon hanging high overhead disappeared into the clouds, and the earth instantly darkened. Only a few stars are still dotted in this boundless darkness, and the dullness and depression of the black shuttle. The chirping of insects suddenly stopped, and only occasionally a gentle breeze blew, making the leaves and grass rustle in the distance, as if there was something hidden in it.

The two of them tiptoed to get closer and closer to the imperial study. Zhaoyun leaned his back against the wall, listening to the subtle footsteps of the two getting closer and closer, his heart became nervous, and he tugged at the corner of his clothes tightly. Su Zidui trapped her between the wall and the bookshelf, looking down at her frowning and biting her lip nervously, and secretly mocked in her heart.

With a squeak, the door of the imperial study was slowly opened from the outside, and a large amount of moonlight poured into the room in an instant, casting a bright light and shadow on the ground. Immediately, two figures blocked out part of the light.

Zhaoyun involuntarily held his breath, and Yu Guang looked at the ground tightly, looking at the two black shadows that were getting closer and closer to him, one behind the other, and clenched his fists.

Su Zidu's face was as usual, and his left hand moved to the saber at his waist and clenched it. It's just that under a closer look, the eyes like cold stars narrowed slightly, as if there was a murderous aura gathered.

Zhaoyun glanced at him and froze. He had almost trapped her in a cramped, cramped corner between the bookshelves and the walls, his right hand propped up on the bookshelf above her head, only a fist between them. And he was exuding a murderous aura all over his body, and a layer of cold ice seemed to be condensed under his squinted eyes. Zhaoyun couldn't help but break out in a cold sweat for the two guards who came in.

Thankfully, the two shadows only reached the bookshelf and didn't move forward. Su Zidui loosened her grip on the hilt of the sword.

"The thief has left early, and you may have been dizzy for a long time after being plotted. Let's withdraw as if nothing had happened! The hoarse voice sounded not far away.

"No, if something really disappears, you and I can't afford it!"

The high-pitched voice was a little hurried, and Zhao Yun could identify it as the guard he had seen before, and Wang Dahua as the other person called him.

Zhaoyun frowned as he looked at Su Ziwan in front of him, and then regained his grip on the scabbard.

"Are you stupid? If the emperor knows that something was lost while you were standing guard, you will be punished by the emperor! Even I might be implicated. The hoarse voice admonished.

"One person does things and one person is responsible, and I, Wang Dahua, have always been able to sit upright. Since I let the thief in while I was standing guard, even if I was plotted, I am indeed guilty of dereliction of duty. If I don't bother you, you don't know anything. Let's go! Wang Dahua sighed.

"In that case, brother, I can't help it. Since you don't listen to my advice and insist on going your own way, then I can only say brother, take care! With that, the other hoarse guard walked away.

The guard of Wang Dahua stood in front of the bookshelf for a moment, and Zhaoyun and the others thought that he was still about to move forward, and their sinking hearts couldn't help but rise again.

Unexpectedly, he didn't move forward, just sighed in place, shook his head and walked out of the imperial study, and closed the door.

Zhaoyun was a little apologetic, but also a little sympathetic to the guard named Wang Dahua.

I finally became the guard on duty in the imperial study, and I encountered this kind of thing again. Probably he will be removed from his official position, and he will be reprimanded with a rod. However, just listening to his conversation with another guard, he is a loyal and honest man. Hey, that's a pity. Zhaoyun didn't feel emotional.

When Wang Dahua walked away, Zhaoyun and the others completely relaxed their vigilance.

Zhaoyun was about to move his stiff body, but suddenly found that he and Su Zidui seemed to be too close. I didn't think it was because of the situation. But now, the distance feels quite ambiguous.

Gradually, Zhaoyun felt that his face was a little hot. However, I was still secretly glad in my heart, fortunately it was too dark in the room and the person in front of me couldn't see it.

"Why are you still stunned, why don't you leave quickly and stay here for the night?" In the darkness, Su Zidu's deep and cold voice came.

This person's mouth is really poisonous, and he doesn't smoke it. Zhaoyun secretly sneered, groping forward, but he didn't expect to hit a human wall.

"I just said bad things about me in my heart, but now I am putting it into action?" Su Zidui teased, with a hint of a smile in her cold voice.

Zhaoyun snorted, pretending to inadvertently stomp on his foot and turn his ankle. Zhaoyun felt that this strength was enough for him to be sour when he thought about it.

However, there was no muffled snort she expected.

"I'm sorry, it's so dark that I can't see it, so much so that it stains your shoes and your feet." Zhaoyun said with a smile.

"You really won't let yourself suffer a little loss, Princess Zhaoyun!" A deep voice came from the darkness.

"If only you knew. This princess has always been a person who must repay her eyes. If you offend me by a foot, I will offend you. ”

"Good!" Mu Xici gritted his teeth and said.

"Anyway, aren't you leaving? I'm leaving. After Zhaoyun finished speaking, he walked to the door, pushed it twice, and found that he couldn't push it, only to realize that the door was locked by Wang Dahua outside.

"Aren't you leaving? Why not go? Su Zidui scoffed.

"Since I came with you, you are responsible for taking me away."

As soon as the words fell, Zhaoyun saw the skylight above his head snap open from the inside out, and instantly heard a swishing sound around him, and a figure flew out along the window.

Zhaoyun waited for him to open the door, but after waiting for a while, there was no movement at all. The façade was silent, except for a few insect chirpings coming in through the skylight.

He wouldn't really leave on his own, leaving her here alone. Zhaoyun thought depressedly, and unconsciously scolded him secretly several times in his heart.

It's really a person who crosses the river and demolishes the bridge!

Zhaoyun pulled up his skirt and was about to climb up the wall when he heard the door open from the outside.

Zhaoyun hurriedly hid behind the bookshelf, put down the corners of his skirt, and secretly picked up the bookshelf to peek out.

After not hearing a sound for a long time, Zhaoyun hurriedly pushed open the door and walked out of the imperial study. There was no figure outside the door, and Su Zidui was not seen.

Zhaoyun locked the door and followed the path back to Zhaoyun Palace alone.

Unbeknownst to her, shortly after she left, the open skylight was closed by a black shadow with a click. And that black shadow, a few leaps, gradually disappeared into the night.

By the time Zhaoyun returned to Zhaoyun Palace, it had already passed the third watch.

At this time, the night was thick outside the window, and the people in the gauze tent opened their eyes and looked at the moonlit tent roof, and fell asleep for a long time.
