In the next few days, everything was peaceful, as if nothing had happened. No matter whether it was the Empress Dowager, the Emperor, or the people in Prince Zhan's Palace, everyone who should have taken action was as quiet as if everything that happened was just a dream.

And in Prince Zhan's Mansion, everyone was doing their job carefully. Although everything seemed calm in Prince Zhan's Mansion, everyone could vaguely feel that there seemed to be a big battle between the prince and the princess, which had been suppressed and had never broken out.

However, Zong Zheng Xiaoting seemed a little impatient with this quietness that seemed to be before the storm.

She was clearly swinging on the swing in the small garden, but there was no trace of joy on her face. When Zhou Miao appeared, the person who was originally sitting on the swing had disappeared. Zong Zheng Xiaoting asked anxiously, "How is it?"

"To reply to the princess, it's airtight, there is no news at all." Zhou Miao frowned. From the news he had secretly gathered in the palace these days, apart from the emperor's rage after Gong Yunluo's body was transported back to the palace, he hadn't heard any other news. For three whole days, there was not a single movement, which made Zong Zheng Xiaoting feel uneasy.

"It's also quiet in the prison. This is really unbelievable. What do they want to do?" Zong Zheng Xiaoting narrowed his eyes, his face solemn. "If we can't guess the enemy's intentions, then we will just be beaten passively."

It was at this moment that Chen Xianzhi also came hurriedly.

"Princess!" Chen Xianzhi's forehead was covered with beads of sweat because he had been jogging all the way.

"Why did Doctor Chen come back so soon?" Zong Zheng Xiaoting waved his hand to signal Chen Xianzhi to leave without further formalities, and allowed him to stand up, with a gleam of excitement in his eyes.

Prophet Chen nodded and handed a broken jade pendant and several small porcelain bottles to Qingqing and Xiaohong.

"These things?" Zong Zheng Xiaoting frowned and asked with his eyes.

"These are the suspicious points that I found after I went to the inn according to the princess's request." Chen Xianzhi bowed his head. "According to what the princess said, there is only one person in Yunguang Country who is most suspicious of the person who wants to harm the princess. Although I hope it is not her, I have to start from this person. Moreover, the princess also mentioned how this little mink eliminated this unclear poison. In this case, we can only investigate in the direction of Gong Yunfei."

Perhaps he had experienced too much, and his junior sister was no longer the junior sister in his memory. The more disappointments he had, the less expectations he had before, and the less pain he had felt before. Doctor Chen at this moment had become numb, and after Zong Zheng Xiaoting asked him to set off immediately after returning home, and after he found these clues in the inn, his heart was completely dead.

"Broken jade? Colorful powders?" Zong Zheng Xiaoting took the objects handed over by Xiaohong and Qingqing with a frown on his face. Xiaohong was startled when she saw her master turning over the broken stones.

Zong Zheng Xiaoting was puzzled and asked, "Doctor Chen, don't tell me that these are the things you found in the inn?"

"Exactly!"

"That's impossible. Although the scene was chaotic at that time, I did see everything there clearly. Apart from the usual things, there was only a mess. And under the mess, there was only the jade bracelet that Gong Yunluo often wore, which was broken into many pieces. There was no such jade or other powdery things." Zong Zheng Xiaoting shook his head, denying Chen Xianzhi's point of view and words.

However, Chen Xianzhi pursed his lips and smiled, "Princess, you don't know that there are too many colorless and odorless gases in this world, and there are countless poisons. But there is one thing, it is the princess's wisdom that reminded me and gave me a chance to check according to this clue."

Zong Zheng Xiaoting raised his eyebrows and handed the porcelain bottle and jade in his hand to Xiaohong.

"Princess, do you remember what you said, that when you are outside the door, nothing will happen to you, but as soon as you enter the door, you will feel dizzy and lose consciousness?" asked the Prophet Chen.

After Zong Zheng Xiaoting nodded, he continued, "No colorless and odorless gas can do this, so there is only one explanation, that is, there is a poison spread on the ground, and this person cannot avoid falling to the ground, so as long as he touches the powder on the ground, the poison will spread instantly, and only in this way can the princess standing outside the door be safe and sound."

"So what?" Zong Zheng Xiaoting began to understand why these powders and gravel appeared in the house as Chen Xianzhi had said. However, she was not sure whether it was the same as she had thought and guessed.

Sure enough, Chen Xianzhi’s next words answered her question.

"Princess, colorless and odorless things are not necessarily just gases. In my Ghost Gate, there is also colorless and odorless powder." Chen Xianzhi raised the corners of his mouth with a mocking smile, "And these colorless and odorless powders also added another function because of my improvement later, that is, where the powder is, it can raise colorless mist like a bird cage. With this function, after the gate is closed, the mist will slowly spread these colorless powders to all parts of the door and finally settle the dust.

Spread? Dust settled? Zong Zheng Xiaoting blinked and chewed on Chen Xianzhi's words over and over again, "That is to say, once the mist settles, it will turn into colorless and odorless powder, eventually covering every corner. People who walk through the door are not actually breathing in the mist, but are contaminated by the powder?"

Chen Xianzhi nodded, "That's right! Moreover, this powder can penetrate quickly into clothes with just a little stain, penetrate into the skin through the clothes, and then penetrate into the blood through the skin, and can make people comatose. However, after I improved it, only my master and my junior sister knew about it, so only the three of us know how to use this poison. But..."

Chen Xianzhi's eyes fell on the porcelain bottle in Xiaohong's hand, and he seemed to be mocking himself, "But what little junior sister may not know is that this has shortcomings. When I first improved this thing, I was also very proud of my achievements, but within a few days, my master told me that this is not indestructible. If my master had not cracked the colorless and odorless powder I developed and condensed it, I would not have known that there would be such a shortcoming. Of course, for others, this is an extremely small possibility that will be discovered, but my master and I are both people who pursue perfection, so before we find a way to crack it, we dare not try it at all."

"What's the solution?" Zong Zheng Xiaoting asked.
