Some people study poisons, some people study antidote and anti-poison, and of course some people study making poisons that cannot be tested. "Half Poison" is the most proud work of a professional drug master. "Semi-poisonous" is also called mandarin duck poison, why do you say that? It is because this poison is a super poison that is a mixture of two or even more than two poisons. The biggest feature of this poison is that it is not easy to detect first, and it will not poison one of the poisons after taking one of the poisons secondly. This is the best way to deceive people who have tested drugs, and it is also the poison with the highest success rate. This kind of "semi-poison" can be put in two or three dishes at the same time, so that the target person will die after eating it, or it can be poisoned in the tea of the target person, and he will be poisoned several times. This poison is not only difficult to test but also difficult to find out the cause of death after the fact, so it is called the poison of poisons. It's just that this poison is not only scarce but also expensive, and it is not affordable for ordinary people. Except for the royal family and some top killer organizations, few people know about the existence of this "half-poison". It seems that Yi Tian's death is not simple, at least the masterpiece of a top poison master.

Knowing the cause of Yi Tian's death, Qin Tai and Zhan Xiaoxiao went all out to find the cause of Yi Tian's death. Poison is a vague name, in fact, because of the different poisons, the effect, purpose, and use effect will be different. From the perspective of medical ecology, poisons are divided into two types: animal poisons and plant poisons. Animals are instinctively poisonous, such as poisonous snakes, puffer fish, etc. People extract venom or poison juice from animals, and the poisons they make are relatively powerful, almost all of them are powerful poisons that seal their throats with blood. Although the poison taken or refined by the plant is relatively weak, it is not something that can be underestimated. This poison is not only common but also relatively simple to make because it comes from plants. Compared with more dangerous animals, people who make poisons still like to make plant poisons.

Poisons are divided into paralysis, asphyxia and hemolysis according to the nature of the drug and the condition of the attack. The paralytic poison is the most common, and the price and refinement are the simplest. A poisoned person will be paralyzed all over the body or locally, giving the killer a chance to get close to the target and kill people. In fact, this poison has medicinal value and is used by doctors to paralyze patients. Later, I don't know when it became a tool to assist in killing. Although this poison cannot kill people instantly, it can limit the opponent's ability to move and give the killer a chance to kill. Besides, as long as the dose is large, it can directly poison people. As the name suggests, the suffocation type of poison poison suffocates the poisoned person, and when the breathing is obstructed, the person will be incapacitated, and the poisoned person will suffocate immediately. Blood-soluble poisons are toxic through the bloodstream and can spread over a large area as long as they damage the skin or enter the bloodstream. It is said that there is a snake venom that can make the blood of a poisoned person immediately poisonous, and it can be spread by just a drop of venom. There was once a master of poison who made a bet with someone else, he used such a drop of venom to drop on a fish, the skin of the fish was destroyed by the master, and the venom entered the body of the fish through the skin of the fish. The master threw the fish into the river. As a result, the fish in the river gradually died, and all the fish that came into contact with the fish or ate the blood stained by the fish died. A few days later, the river was full of dead fish, a dozen days later there was no life in the river, and a month later the inhabitants of the river were poisoned. It can be seen that the severity and destruction of this snake venom are so amazing. Through the study of leftovers and the observation of Yi Tian's corpse, Qin Tai determined that Yi Tian was not only poisoned, but also died of a suffocating type of "semi-poisoning". Yi Tian didn't dare to leave Zhumadian easily, so he ordered some food to eat in his room. It may be because of the mood, or it may be because of Yi Tian's professional habits, Yi Tian did not ask for wine. Two ordinary side dishes, a bowl of braised pork, a bowl of soup and a bowl of rice are all Yi Tian wants. Yi Tian will not have not checked it, Yi Tian has also experienced poison, and he did not find anything wrong before eating. According to the furnishings in the room and Yi Tian's death, Qin Tai analyzed that Yi Tian's last thing to eat was soup, because Yi Tian was holding a soup spoon in his hand. It can be seen that the soup is poisonous, and Yi Tian immediately felt suffocated as soon as he drank the soup, but he couldn't speak anymore. The most terrifying thing about the suffocating poison is that it makes the deceased clearly feel the coming of death, but there is nothing he can do about it. Unable to call for help or get up and run away, he clearly felt that it was becoming more and more difficult for him to breathe, and finally he stopped breathing and suffocated to death. Knowing that soup is one of the poisons, it is much easier to find the second poison. The so-called mandarin duck poison means that two poisons are like husbands and wives like sisters and brothers, and they have mutual induction. Qin Tai picked up the soup spoon and dripped the soup on the other bowls of rice, carefully observing the reaction of the dishes, as long as it was poisonous, there would be a reaction. Soon after, the braised pork, which had almost bottomed out that night, reacted, and it was the second poison of mandarin duck poison. The murderer put the important distinction in the soup and the braised pork, and Yi Tian could not detect this mandarin duck poison even if he was careful in advance. Yi Tian is a killer, and the speed of eating must be faster than that of ordinary people, which is a habit and a common sense. Yi Tian is a martial artist, so he is used to big fish and meat, and his usual life is inseparable from wine and meat. Yi Tianlai has a mission here, so not only can he not drink, but he also needs to keep a low profile and can't even eat more meat. Yi Tian was already suffocated, so he couldn't help but order a bowl of braised pork. Because he couldn't drink alcohol, Yi Tian had to ask for a big bowl of soup to serve as a drink. So these two kinds of poisons are in the things that Yi Tian will definitely order, even if Yi Tian doesn't die today, he will definitely die tomorrow. It seems that the person who poisoned him was not only cautious but also knew Yi Tian well, and he was a master.

Zhan Xiaoxiao assisted Qin Tai as an assistant when her husband Qin Tai's body was examined, and Zhan Xiaoxiao found a problem, Yi Tian's left fingers seemed to be trying to point in one direction. Zhan Xiaoxiao followed Yi Tian's finger and looked out, and found a mask, with no words on the mask and only a doll shape. Zhan Xiaoxiao handed the mask to Qin Tai, and Qin Tai and Zhan Xiaoxiao thought of a person almost at the same time, the immortal blissful boy Li Daguan.

Speaking of this immortal blissful boy Li Daguan, he is quite famous in this place. He is not a god but a god, a god stick that has become a thing of the past. It is said that he will never grow up, with a baby face, and he is a poisonous spirit child. As early as ten years ago, there was a child about eleven or twelve years old in the county, who was not only cute but also had good skills. He said that he was born a fairy child and had the ability to be invulnerable. So saying, he took out a bottle of poison, and one drop of the venom poisoned a cow, and then he drank all the poison in three parts, and he didn't do anything at all. Everyone gradually believed in this prodigy and built a temple for him in the county seat to support him. In the past seven or eight years, not only have there been many believers, but he has not grown long at all, and everyone has become more and more convinced that he is the true Immortal Boy of Bliss. More than a year ago, this immortal boy of bliss suddenly disappeared, and no one knew where he had gone. Some people say that he died, some people say that he is crazy, some people say that he was taken away and bled as a tonic, and some people say that his merits will be fulfilled and go to heaven.

In fact, Yi Tian once told Qin Tai that this immortal blissful boy was the master of the branch altar of the Divine Sect stationed here. Not only is the Immortal Bliss Boy not a child, but he has no supernatural powers at all. Yi Tian was not familiar with this altar master, so he didn't know much about it. However, he had heard some people talk about the immortal Bliss Boy Li Daguan, and people in the organization said that he was a ghost who was afraid of death. Because he has been taking a drug that hinders his development for a long time, he looks like a child. As for his invincibility to poison, it is because he has been taking poison for a long time, and the antibodies produced by the poison will not have problems, and it is not a supernatural ability. Not long after Yi Tian came here to be the owner of incense, this Li Daguan disappeared. Originally, I thought that he had been kidnapped by some people or people from the yamen, but later I learned that he had taken the organization's funds without authorization and defected. Yi Tian received an order to find Ma Guilan and Li Daguan, and if the other party resisted, he would kill one of them on the spot. A certain big man of the Divine Sect privately ordered Yi Tian to find Ma Guilan, and completely solved Ma Guilan, so Yi Tian first looked for Ma Guilan. Yi Tian came to arrest and deal with Li Daguan, but he didn't expect to be poisoned by Li Daguan in the end, which is really a strange thing.

Since Yi Tian died in Zhumadian, no one else had been in and out of Zhumadian at this time. Therefore, the murderer is the person in Zhumadian, and it is impossible for the villagers to be the immortal blissful boy Li Daguan. At this time, there were guys and two dogs in Zhumadian, as well as a horse gang. The caravan arrived in the morning, and originally planned to take a break and hurry, but I didn't expect a horse's hooves to crack, so I had to change the horseshoe. The caravan decided to divide some of them to continue on the road, and some of them stayed and went on the road together in the afternoon after nailing the horseshoe. The members of the caravan who stayed behind were all in the front yard, and although they had not been to the kitchen, it could not be ruled out that some of them had secretly poisoned them.

Yi Tian would point to the mask for no reason, could it be that Yi Tian discovered some secret? Is the baby-faced mask really talking about the immortal Bliss Boy Li Daguan? There were seven or eight people in the caravan, and although there were two young people, they didn't look like the legendary immortal boy of Bliss, Li Daguan. The other five big and three rough men are even more unlike the immortal Bliss Boy Li Daguan.
