Only a quarter of an hour.

Very short.

Chen Ji stopped talking nonsense and quickly looked around the study room. His eyes stopped on the scattered books and rice papers, and he quickly flipped through the books on the bookshelf.

"The rice paper is all blank, and the books are all that can be seen in the world. There is nothing included in them," the white rabbit reminded.

Chen Ji turned around and walked into the courtyard.

This is a two-entry courtyard. He carefully observed every detail of the courtyard, trying to find clues. Chen Ji knew in his heart that he was not completely sure of finding clues. He just said that because he was facing a group of murderous people.

A blinking snake or scorpion might die immediately if you didn't say so.

As time passed by, Yunyang gradually lost patience: "It's too slow, too slow. We need to add a game. Have you seen the sycamore tree in the yard? While you are looking for clues, every time a leaf falls,

I will prick you with a needle."

As soon as he finished speaking, a leaf fell off the branch.

Yunyang raised his hand in the air, picked up the withered yellow leaves, and sighed: "You are really unlucky."

With that said, he walked up to Chen Ji and pierced the boy's mouth with a needle.

Chen Ji's face suddenly turned red, and his whole body bent down due to severe pain. It was cold autumn, but big beads of sweat fell one after another on his forehead.

He scolded Yunyang for being a pervert in his heart, but he couldn't relieve the pain at all.

Yunyang said slowly: "The time lost due to pain is also counted in that quarter of an hour."

Chen Ji slowly straightened up while holding on to the sycamore tree, and moved into the kitchen step by step. He had to find the clue before the second leaf fell!

In the kitchen, there is nothing more than a blue brick stove and a pile of bottles and jars filled with condiments.

The house is clean and tidy, with nothing superfluous.

After checking all the bottles and cans, Chen Ji walked out of the kitchen. However, as he just walked out of the kitchen, he stood still.

He murmured to himself: "I always feel that something is wrong, as if I have missed some details."

Yunyang leaned against the door frame of the kitchen and yawned, playing with the silver needle on his fingertips: "I'm almost out of time. It seems I wasted a quarter of an hour."

Chen Ji still stood still, thinking hard about what details he had just missed!

While he was thinking, another leaf fell from the sycamore tree, and Yunyang stabbed another needle behind his ear.

In an instant, Chen Ji bent over and squatted on the ground, curled up like a shrimp, unable to move, and almost went into shock.

But this time, without waiting for Yunyang to urge him, he straightened up and returned to the kitchen, taking out two jars, which were filled with fine white crystalline powder.

Yunyang glanced curiously: "Two cans of salt, what's the problem?"

"Why are there two jars of salt in a kitchen?" Chen Ji said, pinching a fine white powder from one of the clay jars and rubbing it on his fingertips: "This is not salt."

"Not salt?" Yunyang was curious. He and Jiaotu were good at killing people and resolving the aftermath, passing blame, and grabbing credit. They were really weak at finding clues.

Chen Ji held out his finger to Yunyang: "Taste what it tastes like."

Yunyang said angrily: "You are quite cautious, what if it is poisonous? I won't taste it."

The white rabbit laughed out loud.

If it weren't for the corpses here, this snake-scorpion girl would be quite cute when she smiles.

Yunyang said with a cold face: "Try it quickly."

Chen Ji pinched some white powder and stuffed it into his mouth: "It's very astringent in the mouth and has no obvious taste."

He was lost in thought.

What could this thing be?

Chen Ji quickly searched the memory in his mind, trying to find the answer from some of the books he had read.

Wait, this is alum!

Some popular military intelligence books have mentioned that alum is one of the main materials used to write secret messages in intelligence warfare.

Use alum water to write, and the writing will disappear after it dries. This espionage technology originated in the 13th century and was frequently used by spies until World War I and World War II.

Chen Ji thought for a long time, and he was sure he had found the answer: Jing Dynasty spies used alum to write secret messages. Zhou Chengyi hid this thing at home together with salt to confuse the sight, and placed it so close to him, so convenient

place, indicating that secret letters should be exchanged very frequently, so... Zhou Chengyi's home must have secret letters between him and other spies.

He immediately took the vinegar jar from the kitchen and returned to the study. He spread the white rice paper on the table, tore off a piece of cloth from himself, and gently wiped every part of the rice paper with vinegar.

He wiped five or six pieces of rice paper in succession, but did not get the answer he wanted. Time passed by, and in the cold autumn, fine beads of sweat formed on his forehead.

He turned to look at Zhou Chengyi and saw that his face was calm and not panicked.

Did you guess wrong?

No, absolutely nothing wrong!

At this time, a cold wind blew, and the yellow leaves on the sycamore tree fell like rain. Yunyang smiled: "You are not lucky enough..."

"Found it!"

"Huh?" Yunyang's eyes were attracted.

When the traces were wiped onto the twelfth piece of rice paper, a line of red letters appeared on the place where the light yellow vinegar liquid had been wiped: "Li Ji Sweet Water Shop in Lijing Lane, east of the city. If you are in danger, please go there immediately."

Yunyang's eyes suddenly brightened when he saw these handwritings: "This is a new base established by spies from the Jing Dynasty. Maybe a big shot from the Military Intelligence Department of the Jing Dynasty has come to Luo City!"

As he said that, he looked at the white rabbit and said, "You have great achievements!"

The White Rabbit thought for a while: "Kill this kid, and the credit will go to us."

"No, I promised not to kill him. Anyway, he is not from our Secret Service. The credit will always be on you and me."

"All right……"

Looking back at Zhou Chengyi, the Jing Dynasty spy's face was ashen.

He stopped pretending, and immediately pulled out a hidden soft sword from his belt and rushed towards Chen Ji, intending to kill him desperately.

As the spy from Jingchao rushed forward, he lost his embarrassed posture in the blink of an eye and became as ferocious as a ferocious beast.

Chen Ji flew back, and the rabbit on the other side suddenly jumped up like a phantom, like a butterfly flying.

But she saw her blocking Zhou Chengyi's path. As the two sides passed by each other, the silver needle between her two fingers stabbed Zhou Chengyi's waist like a dragonfly touching water.

With a bang, Zhou Chengyi lost his strength and fell to the ground, raising a cloud of dust.

It was at this time that a stream of cold air surged out of Zhou Chengyi's body, like a gray and flowing dragon in the dark night, and penetrated into Chen Ji's body.

This was a feeling he had never experienced in his seventeen years of life. The ice flow was like the glacier water on the snow-capped mountains, cold and clear, and kept swimming in his blood.

Where did this ice flow come from? Why did it come? Chen Ji didn't know.

The scene he saw tonight would only appear in movies in the past. This world is completely different from the world he knows!

Chen Ji observed Jiaotu and Yunyang and found that they did not seem to have seen the scene just now. Could it be that he was the only one who could see it?

Seeing that Zhou Chengyi was no longer able to resist, Yunyang turned to look at Chen Ji with interest: "How can you, a medical apprentice, understand this?"

Chen Ji explained without thinking: "Alum can be used as medicine. It has the effects of stopping bleeding, treating ulcers, and relieving pain, so I know something about it."

"Oh?" Yunyang pinched some alum from the jar and stuffed it into his mouth: "I just happened to have a bad temper recently, and I got an ulcer in my mouth."

Jiaotu stood upright on Zhou Chengyi's back: "Why don't you chat for a while? Let's send someone to Lijing Lane first to pick up the Li Ji Sweet Water Shop."

Immediately, eight men in black on standby went out, mounted their horses, and galloped straight towards Lijing Lane.

The crisp sound of horse hooves trampled on the bluestone road at midnight, tearing the tranquility of the night.

Chen Ji asked: "Can I leave?"

"Um...I'm afraid not," Yunyang shook his head.

"Repent?"

"That's not true. I just said you could live, but I didn't say I would let you go." Yun Yang dusted himself off and said, "I have to take you to the inner prison and interrogate you properly."

OK."

"Interrogation for what?"

"For example, why do you, an apprentice in the Imperial Medical Clinic of Prince Jing's Mansion, show up at Zhou Chengyi's Mansion in the middle of the night? Has Prince Jing already connected with the Northern Jing Dynasty through Zhou Chengyi, intending to use Jing Dynasty's power to plot rebellion?" Yunyang spread his hands: "Look,

I have a lot of questions to ask."

Jiaotu seduced: "Zhou Chengyi is just a small county magistrate, but if you can bite out Prince Jing, we will give you glory and wealth!"

Chen Ji secretly sighed that the complexity of his situation seemed beyond imagination.

Where is Jing Chao? Who is Prince Jing?

Were the social relationships of the deceased so complicated during his lifetime?

He responded: "I came to deliver medicine, and I was innocently implicated."

Chen Ji answered this because he also saw two packages of medicinal materials with "Taiping Medical Center" written on them in the kitchen, wrapped in yellow paper and placed next to the casserole stove in the kitchen, unopened.

Yunyang shook his head: "This is just your one-sided statement. I only believe in the answer I got from the interrogation."

Chen Ji changed the topic: "Do you want to arrest that big shot from the Military Intelligence Department of Jing Dynasty?"

"His captors have gone."

"You can't catch that person at the Tianshui Shop in Lijing Lane. It's obviously just a place to help Zhou Chengyi escape. There won't be any big shots."

Yunyang looked thoughtful: "Do you have any other clues?"

Chen Ji kept silent.

Yunyang came to Chen Ji, held the slender silver needle between his middle and index fingers and tapped it gently on Chen Ji's shoulder.

In an instant, Chen Ji felt a heartbreaking pain coming over him. In just a few breaths, his clothes were wet with sweat. However, the pain came and went quickly, and it disappeared in just a few breaths.

There was no trace, as if it was all an illusion just now.

Yunyang said casually: "I still have many more methods like this. Over the years of traveling around the world, there are only a handful of people who can withstand my three injections."

However, Chen Ji remained silent.

Yunyang stabbed another needle on the back of Chen Ji's hand. The young man's body could not stop trembling, but he remained silent.

Yunyang stabbed him two more times, but Chen Ji remained silent.

"Can you handle this?" Yunyang exclaimed.

The next second, Chen Ji suddenly took out broken pieces of porcelain in his hand, and tremblingly wiped them towards the main artery of his neck!

The broken piece of porcelain had been hidden in his hand all along.

The broken pieces of porcelain suddenly stopped when they reached the neck, and Yunyang grabbed Chen Yi's wrist and said, "Preventing death?"

"Forget it, if you delay any longer, the great credit will be lost." Jiaotu raised three fingers: "I swear on the honor of my mother, as long as you tell us the information to help us accomplish the feat, I will give you your freedom."

Yunyang raised three fingers: "I also swear on the honor of my parents that if I lie, I will send them to eternal hell."

Chen Ji remained silent, thinking about the value of this oath.

People in this era are probably superstitious, so the oath carries a very heavy weight... No, I still can't believe it.

But if you show enough ability and make yourself useful enough, can you gamble your life?

Finally, he gasped and said: "The rice paper must have been written with alum water when it was bought. It was probably written by the big shot of the Jing Dynasty you mentioned, so if you are looking for clues at this time, you should not go to Lijing Lane.

, but look for the shop that sells rice paper. This shop is the most important channel for information."
