When Chen An returned home, he went into the secret room and continued to study the sword book. In the end, he still didn't track down the man to detoxify him, since he ran into himself, it could only be regarded as his bad luck, and the eight characters were too soft. Even though the Dark Division's tracking technique is unique in the world, Chen An doesn't have the idleness and kindness, and bothered to be an inconsequential little person.

As for why the other party haunted the Lin Mansion and what tasks he had, he didn't care about it.

It's still like a few days ago, he cultivates as usual and sleeps as usual, and he doesn't have the slightest worry about going south, since Ting Wei said it, the preparations will naturally be arranged for him, and he doesn't have to worry about it at all.

Early the next morning, Chen An took two too illusory spiritual steps, and exercised in the morning. This set of footwork is an ancestral heirloom, even if it doesn't work much, he still can't bear to waste it. After walking down with footwork, the feeling of fatigue when I first woke up was gone, and my spirits were greatly lifted, and I thought that I should also prepare to leave Beijing.

He went out of his residence to find Xu Yuan and a few people, and now they have all got the idle position of Mingsi, and they don't need to lick the blood with a knife, so they are naturally very happy, and they pulled Chen An to a tavern, and pushed the cup to change the lamp to celebrate. During this period, they couldn't help but sigh when Chen An stayed in the dark division and couldn't be with everyone, and they were envious of his step-by-step ascension.

Chen An is not a person who likes to be lively, and even because of childhood changes, he is wary of people. But the people here are colleagues who have shared life and death with him for many years, and now they are working in other places, and they don't know when they will be able to meet again.

Everyone drank from noon to sunset, and then they were reluctant to leave one after another. Chen Andong staggered to the courtyard of his house, locked the door tremblingly, and he was the only one here. He was shaken, and his eyes returned to clarity. Today's Chen An's internal strength has been completed, and his martial arts have already entered the house, so he naturally will not get drunk, but he is just deliberately suppressing his true qi to prevent the wine from being discharged from the body, and he will have a scene with everyone.

After returning home, he intended to continue to study the sword spectrum, and suddenly his heart moved, although his own martial arts have been slightly successful, but must not be complacent, you must know that there are people outside the world. If you encounter a powerful opponent in the future, you will have to use your housekeeping skills to deal with it, so it is better to prepare more while you have time now.

With this in mind, he went to the room where the ghost uncle lived and entered the secret room inside. There are six rooms in this secret room, which are divided into three on the left and three on the right, and are connected by a corridor.

The three rooms on the right are cells, one of the three rooms on the left is used to store insect poisons, and the remaining two rooms are the same as the insect Gu room, consisting of many grids, but these grids are drawers one by one, in which some sun-dried poisonous flowers and poisonous herbs and many ordinary medicinal materials are placed.

The last room is the place where Chen An uses to dispense medicines, and all kinds of tools are available. At this moment, a large tray three feet square was piled up in the room, and the tray was filled with air-dried white lumps.

Chen An's eyes fell on it, and after thinking for a long time, he pinched a piece the size of a fingernail, ground it into powder, and set it on fire.

The white powder didn't seem to burn easily, there was no fire, only a few scattered red dots flickering in between, and what was even more strange was that all the combustible things would rise smoke and dust, but the sky above the powder was empty, not only that, not even a trace of peculiar smell.

But this thing only burned for a moment, and Chen An felt top-heavy and weak. He was shocked in his heart and hurriedly extinguished it, and used special techniques to tap several big points on his body again and again before it was relieved.

"This kind of incense medicine is so domineering. Chen An couldn't help but whisper to himself. You must know that when he can't practice internal force, he uses poison instead of internal force to act, and achieves a body of poison. Naturally, he is extremely resistant to various toxins, and he is highly toxic to other people's intestines, which may be a delicacy for him. He even created his own method of blood circulation, which can naturally expel poison from the body, and it is not an exaggeration to say that it is not invasive. This incense can have an effect on him just a little, which shows the poison, but he is not surprised, for him, the stronger the poison, the greater the help.

Among the poisons he knew, the only ones who could completely ignore his anti-poison physique were the ** named Jinyu Cartilage Fragrance in his hands. Other poisons, if any, can cause him harm, but they are limited.

He put down the tools in his hand, turned to the secret room of medicinal materials next door, and opened a drawer in a corner, there were no medicinal materials in it, but there were two thread-bound books lying quietly, one blue and one purple.

The blue-skinned book had the words "Ji Shifang" written on it, and the handwriting was elegant, and Chen An didn't open it for a long time, and put it back into the previous drawer.

The purple book was written neatly with the words "Analysis of the Five Poisons", the handwriting was like a children's book, Chen An quickly turned to the end, took out the pen and ink, and wrote the words "Jinyu Cartilage Fragrance", the handwriting was the same as before. He worked hard to write down all the medicinal properties and pharmacological production methods.

After a while, after the recording was completed, he was satisfied with the ink marks on it, this "Analysis of the Five Poisons" is his hard work for more than ten years, not only including many unknown poison preparation methods of the secret division, but also recording the poison recipes he created himself. What he is most proud of is that he has never thought of before, divides poison into five elements, regards it as five poisons, and combines it with martial arts to create unprecedented poisonous skills.

Among them, gold poison, from a variety of ores, such as stone gall, dansha, also known as the poison of gold and stone, the power of the five poisons, not only difficult to eliminate, a careless, but also harmful to future generations, the effect is comparable to the ancient wizard's curse technique.

Wood poison does not need to be explained, flowers and trees can be used as medicine to become poison, and there are many types, poisoning symptoms are even more strange, and the secret division is combined with various tortures to interrogate prisoners, so that life is worse than death.

Fire poison is self-generated for the human body, just like corpse poison, and like special internal strength that hurts people's lungs, makes people's own circulation disharmonious, and gives birth to toxins. It's as if the cold poison and flame poison in his cold ghost claws are all classified as fire poison.

Water poison is the opposite of wood poison, snakes, insects, rats and ants all carry water poison, and southern Xinjiang Gu poison is also among them. Most of the poisons commonly used in rivers and lakes are water and wood poisons.

In addition to mosquito bites with water poison, environmental changes, temperature changes, and soil quality changes will cause people to get sick and give birth to toxins, which is soil poison.

By studying the five poisons, we can make a blood-sealing poison, and if we understand the five poisons, we can solve all the poisons in the world. Chen An's meridians were damaged and his internal force was mediocre, so he used the technique of the five poisons to make poison hidden in the body to replace the internal force. When fighting with people, he will never resist head-on, but use his body to retreat with one touch, wait for people to attack his heart with poison, and then clean up.

Just like when he killed Zhang Yong, he first lured him to attack his heart with poison, and then used the Yin God Finger to take his life, and the Yin God Finger is a poison technique that needs the assistance of toxins to practice.

There is no absolute poison for its use, it varies from person to person, it is possible that one toxin is useless for some people, but it can be fatal for others. People have different physiques and naturally have different resistance to poisons.

Chen An was poisoned every time, and he was invincible, and he learned more about the target's living environment and physical resistance through the intelligence of the secret division, and specially formulated a package for him.

Now that he has advanced in martial arts, he has a deeper understanding of pharmacology, and has recorded some of his practice and insights, and "Analysis of the Five Poisons" is even fuller, and it is definitely a contemporary martial arts cheats. In Chen Anxin, it is not far behind the century-old "Heavenly Will Sword Spectrum" inherited by Naming Sword Villa.

He put it back in the drawer, and glanced at another "Ji Shi Fang", which was his father's life's work to write the medical scriptures, along with the scroll of the too illusory spirit step handed to him, but unfortunately he is now burdened with a sea of blood, how can he study kung fu medicine, so he only tasted the content of it, and did not study it deeply.

Ruthlessly closing the drawer, Chen An came to the previous secret room again, ground all the gold and jade cartilage incense in the tray into powder, put it in a large porcelain bottle, and wanted to leave with one hand holding the porcelain bottle.

But after taking two steps, he turned around and carefully examined the chamber. The corpses in the secret room were all cleaned up by the ghost uncle when he left, saving Chen An a lot of trouble, and the bone cup containing poisonous insects was also taken away by him, and there was no living thing left in the stone room.

Chen An closed all the ventilation holes in the stone room, completely sealed the stone room, and then came to the corridor in the middle of the six secret rooms, took out a purple incense stick and lit it. This incense stick was very strange, and the smoke and dust that ignited it did not float upward, but sank downward, and in a moment it was covered with six stone chambers, covering the ankles.

Chen An smiled slightly, walked out, took out a sealed porcelain pot, opened the wax seal, and took out some transparent paste, all of which were painted on the stone door, both inside and outside. The paste applied to the stone wall of the stone gate turned into the same color as the earth and stone, which was extremely magical.

At this point, Chen An was relieved, and returned to his bedroom with the porcelain vase, and put it on the cabinet used to divide the middle of the bedroom, which was full of antique pottery. Except for Chen An, no one knew that it was full of all kinds of poisons, and so on. He was born vigilant, this is to prevent someone from attacking, he can use the enemy at will, very convenient, but not conspicuous, it is really the best of both worlds.

After that, he tidied up his clothes again, and took out a belt, about a finger thick, which was divided into countless dark compartments, containing various kinds of medicinal powder pills, as well as a pair of sleeve guards......

Among them, the two ** he carries the most are the soul scattering and the golden jade cartilage incense, these two ** are colorless and tasteless, and people unconsciously fall on the road, which is the most suitable for sneak attacks. And in a way, it is far better than strong poisons. But any master, martial arts practice to a certain level, will inevitably be deaf and clear, the six senses are far beyond ordinary people, and there is always a sense of whim for danger. Poison is deadly and will always be felt, but it won't. So even if it is a top master, there is only one word against **.

And these two ** are still Chen An's most proud works, among which the most terrifying soul separation was inadvertently developed by Chen An, and he thought he was the most proud. Not only can it cause people to hallucinate, but it can also merge with any one or several poisons, without damaging the poison's toxicity and reducing the resistance of the poisoned person to the poison.

Because the internal strength of the real master of the inner family has been able to suppress the toxin, so the martial arts practice to a certain level can even be invulnerable. Soul Separation is aimed at this, confusing the consciousness of the poisoned person so that it cannot suppress the spread of poison at all.

With these two strange poisons, Chen An's heart suddenly settled down, and he was busy until the third watch before going to bed to rest.
