The structure at the top of the cell is even more solid than usual. It's impossible for a prisoner to descend from the sky! "

"Ah, so annoying. That's impossible. That's also impossible. What exactly is it like? People are already dead!" Ruo Su stamped her feet. 'Why is it so complicated? I truly wronged her. I can't believe I have to think about so many things. Sigh …'

"Ruo Su, the general and leader are already annoying enough. You can just stop messing around!" Feeling helpless, Cheng Ziheng pulled Ruo Su over and advised her to be quiet.

Liruo stepped forward and carefully examined the Prefect's corpse, but did not discover any injuries. Xuanyuan Mo had also tried it. There was no poison in the food, and neither was there any poison in his body …

The cell was so quiet that only the sound of breathing and searching for bodies could be heard. It was extremely quiet.

"General!" At this moment, a small soldier came to report. "A couple came from the Imperial City, claiming to be friends of the General and Madam. They said that they need to see you!"

"Please come here directly!" There was no need for the soldier to say anything, the two already knew who it was, and Li Ruo immediately cut him off.

Not long after, Su Lin and Mo Shang walked in. They looked a little worn out from the journey, but it did not affect their beautiful appearance at all. Indeed, these two people were beautiful scenery wherever they went.

Su Lin was excited to see the body. She took out a glove from her pocket and started to examine it.

Su Lin watched the body very carefully. She didn't want to let go of every single part of the body. After understanding her habit, she walked up to the body and helped her do some flipping and other things from time to time.

The two of them had a tacit understanding of each other. The two men were out of martial arts and could only stand to the side and watch. However, the two women needed too much time, so Xuanyuan Mo and Mo Shang had changed from standing with cupped fists to leaning against the door of the cell.

Li Ruo glanced at them casually, looking exactly like the two sect gods, with the same cold expression on their faces. No wonder he was able to become the best brother.

"How is it?" After a long while, Liru took the towel from the guard and wiped her hands.

"He's poisoned!" Su Lin was very sure.

"But I've tried before, there's no poison in the dish, and there's no poison in his body either!"

Xuanyuan Mo did not understand. Furthermore, Li Ruo had said before that no one would be able to enter this kind of arrangement.

It was impossible to take the opportunity to poison them.

Furthermore, the expression of most poisons would change after they entered the body. It would also take some time for the poison to act up. The Chief Officer had a calm expression on his face. These were not the symptoms of being poisoned.

"The poison in his body is unique to the imperial family. I remember the last time I saw him was during a palace banquet, and Yeye said that she was very curious about why a woman was interested in his corpse. That's why she wanted to know about me!"

"I told him that if he wanted to understand me, he would have to trade for something that I'm interested in. He promised me many benefits, but even I couldn't see through it. In the end, he could only helplessly take it out!"

"This poison is called 'Beauty Yu'!"

"Seeing Mo Shang's tasteless face, Su Lin quickly changed the subject." It was said that the taste was as light as tea, and there was even a hint of sweetness in the drink. It was no different from a normal candy! I heard from Yeye that once a Yu Mei enters the body, she will cause a person to die quickly and without any pain at all. Furthermore, because the taste is good, a blissful look would appear on the face of the person. Su Lin picked up the Prefect's wrist, only to see it protrude from his arm …

However, many densely packed red spots appeared, looking somewhat similar to eczema.

"Before, I always thought that Yeye purposely exaggerated the effects in order to arouse my curiosity, but after that, I did experiments on animals and confirmed what he said. It's not wrong at all. The strength of this medicine is even greater than what he said."

"I heard that there is a secret poison in the royal family of Qing Li Country. It is said that it was specially made for concubines who make mistakes in the harem. This poison is never spread to outsiders!"

Xuanyuan Mo voiced out his thoughts. This was because the Emperor of Qing Li believed that all the mistakes they made while they were alive had already been repaid when they died. Since they had already been repaid, after death, they should have been able to live a bit more comfortably. This was the reason why Emperor Qing Li specially made this kind of poison. He also ordered for the formula not to be spread to the outside world and for the antidote not to be privately concocted. Those who disobeyed his orders would be the ones to make the final decision.

I've heard that because these orders are too frightening and some of the people who made this medicine have already been beheaded because of mistakes, no one dared to make the same mistake from then on.

"That's right. Since this poison's power is so great that it cannot be spread outside, it means that the things that the Prefect knows are very important. Thus, he must die."

"It's just a mere government official, but it's actually worth it for them to use such a poison. This is definitely not a simple matter!" Although he did not know what the problem was, and the guard leading the way only said that Xuanyuan Mo and Liru were interrogating the Prefect, Mo Shang was still very keen on finding the problem.

"Yu Mei …" "Liru pondered." Su Lin, how can I dissolve Yu Mei? "In other words, what conditions do I need to achieve the maximum effect of the medicine?"

"As long as it comes into contact with temperature and blood, it will automatically dissolve."

"In other words, I have to inject it into my body, drink it, or enter my skin before there will be a reaction?"

"Something like that!" Su Lin nodded. She raised her head and looked around, but didn't find anything suspicious. She then continued, "This place is heavily guarded, ordinary people can't enter!"

"That's right, we've already done some investigation. From last night to today, no strangers have entered. The people on duty last night have also been investigated. There are no problems!" Xuanyuan Mo followed up.

"No, there must be a loophole!" Mo Shang thought for a moment. He had personally seen the Yu Mei that Su Lin mentioned before when he was conducting his experiments. After melting, it would be colorless and tasteless, and even doctors would be unable to find any problems with it. It was said that the pill was the best in the world because there was no cure.

"That's right, there must be a loophole!" After saying that, she checked the structure of the cell again, and finally fixed her gaze on the air vent.

"Su Lin, what do you usually need to be for a beautiful lady like Yu Yu Sheng? How big is it? "How much does it take to get into the body before there's a reaction?"

"Ordinary porcelain bottles can do it, but there isn't a need for too much. As long as it enters the skin, even a tiny bit of it would be fatal!"

As Su Lin said this, she too lay down on the ground and took a closer look.

The ground was very dark, so it was hard to tell. Xuanyuan Mo ordered his men to light up all the fires in the cell, then he took out a small night pearl and passed it to Li Ruo.

The cell was as bright as day. They quickly found a few small silver needles on the floor and lit them up.

"Xuanyuan Mo, go up and check if there's anything special about that vent!"

"I'll show you personally!" He knew that he wasn't as meticulous as Liru, so Xuanyuan Mo simply hugged Liru and leapt up.

"Alright!" In just a moment. The two of them landed steadily on the ground.

"I can already confirm that the other party sent the silver needles in through the air vent!" Because it was special, the ventilation holes basically wouldn't be cleaned. As time passed, a lot of dust was left behind. And just now, Li Ruo found a few very small marks within the dust, as if something rubbed against it and left behind.

At the same time, Su Lin also found some new traces on the body.

"These places should have been pierced by silver needles because the red spots around them were obviously deeper than other places. However, because they were stabbed too deeply, I can't be sure. I'll have to dissect them before being able to come to a conclusion!"

"Alright!" Li Ruo nodded, and once again carefully examined the structure of the cell.

"As things stand, the only flaw is the air vent. However, in such a small place, how did the other party manage to throw these silver needles at the prefect's body? " Mo Shang had also considered this, but at the moment, he had no idea how his opponent would operate.

After all, there was a five meter long wall outside and a ten meter wide river behind it. Drinking water was so fast that it was impossible to walk on it.

"No, the other party only knows the general location of the Prefect and not that he is in this cell. If you don't believe me, you can go to the other three rooms to check and should be able to find the silver needles." With that, someone went to each of the cells to search carefully, and after a while, they found the silver needles.

"Actually, from the silver needles scattered on the ground, one can tell that Lady Yu was an extremely precious poison. If the secret on the Prefect's body wasn't so important, how could he have used such a thing?"

"Although the air vents are small and the situation outside is not too optimistic, that does not mean that there is no other way." After saying this, Liruo lowered her head and said, "Maybe we can give it a try!"

By the time they reached the other side of the river behind the prison, an incense stick of time had already passed. Everyone consciously looked at their surroundings and discovered that there were traces of people lingering around.

"It seems like the murderer has been here for a long time!" Mo Shang looked at a footprint that had been stepped on many times, and said directly.

"That's right, he must have been here since the Prefect came in. Perhaps he was here to supervise the Prefect, but when he found out that the Prefect was about to speak the truth, he decided to kill him!"

"Maybe they wanted to kill the magistrate from the beginning, but because the location of the cell is special and it's not easy to get close to it, they put it on hold. However, when the magistrate told me that he wanted to recruit them, they made a plan in advance!" Lo Ruo looked at several footprints of varying depth. Some were recent, some were old, the old ones had already been treated, and the size and appearance of the footprints could not be seen.
