When Ao Wuwei left, Lu Feng began to look at the pages he left behind, which was different from the first two books on poisons, this broken poison scripture introduced in detail how to drive the detailed process of toxin refining in the body.

Similar to the same system as many orthodox cultivators on the Western Continent of the Shenwu Great World, although the cultivation of poison is with the help of external forces, it is also a kind of cultivation of internal energy, and the toxins that are channeled into the body are called poisonous energy.

With the help of the guidance of the cultivator's mind, the energy circulation of poisonous energy in the body is formed, so as to increase the body's adaptability to poisonous energy, so as to achieve the purpose of allowing people who practice poisonous energy to use poisonous energy to refine the body and borrow external force for their own use.

When the body is completely adapted to the poisonous energy, a cultivator who cultivates the poisonous skill can have the same combat power as an orthodox cultivator.

The Poison Sutra mentions that cultivators who fight against low-level orthodox cultivators and cultivate poison skills are superior to low-level primordial energy cultivators in terms of attack and energy attributes.

As for how to cultivate after becoming an orthodox cultivator, Lu Feng didn't dare to confirm it, because this poison scripture was not complete at all, only two pages. And Lu Feng's Tianwu Great World in his previous life was slightly different from this Great World.

Early the next morning, Ao Wuwei didn't know where to find a blood-red plant and brought it to Lu Feng.

The plant in front of me was less than half an arm long, the finger-thick branches, the branches were red, as if they were about to be printed, the red was dripping, and there were three small black flowers blooming at the top of the plant, exuding a fishy sweet fragrance.

Lu Feng recognized this plant at a glance, it was a very rare blood refining grass, and it had a very detailed introduction in the poison book that Ao Wuwei gave to Lu Feng.

Blood refining grass generally grows in the depths of the death swamp of the Western Continent, which is very difficult to obtain, and it is a giant poisonous plant, once this plant is swallowed, even people in the blood exchange realm will die because of blood boiling, and even ordinary primordial beasts can't resist its toxicity.

Only a few high-level cultivators were not afraid of the toxicity of the Blood Refining Grass. There is another use of the Blood Refining Grass, that is, taking the Blood Refining Grass has a certain chance to help people who have been cultivating for a long time and have reached a bottleneck to break through their own cultivation barriers.

It's just that there are very few people who dare to use it, because the chance of using the Blood Refining Grass to break through the cultivation barrier is only one percent, and the negative effects of taking the Blood Refining Grass are also very large, and the user needs to take a very big risk, this poisonous weed is undoubtedly a daunting thing for the cultivators of the Shenwu Great World.

Looking at the poisonous plant that Ao Wuwei placed in front of him, Lu Feng felt a slight chill in his heart.

"Lu Feng, do you know this plant?" Ao Wuwei asked with a slight smile.

Lu Feng nodded: "Blood Refining Grass!Master, did you bring this plant for my cultivation of poisonous functions?"

"Haha~~~ Yes, this poisonous weed is amazing! If you can absorb its toxins, it will effectively activate the energy in your blood, and achieve the effect of refining the meat god, and after success, you will absorb other toxins in the future, and it will have twice the effect with half the effort. When Ao Wuwei spoke, a wisp of heat and madness flashed in his eyes.

Listening to Ao Wuwei's words, Lu Feng was secretly stunned in his heart and did not speak.

"Are you afraid of its toxicity? You can rest assured that the teacher has been prepared for this for a long time, and you just need to do what I say. Although this poisonous weed is very toxic, it is also very powerful. Like some spirit herbs, poisonous plants can also provide cultivators with a lot of medicinal properties and energy, the key is how to use them!"

"I see, Master, just tell me what to do later. Lu Feng looked at the blood refining grass beside him and said.

"Haha~~~ That's right, if you can take this step, Ten Thousand Poison Peak is equivalent to a mountain spirit extract, let you ask for this blood refining grass, although it is extraordinary, but it is nothing on Ten Thousand Poison Peak, and when your poison skill cultivation reaches a certain level, Ten Thousand Poison Peak will provide you with the most adequate cultivation guarantee. As he spoke, Ao Wuwei stretched out his right hand with a skin glove and picked up the blood refining grass that was placed not far from Lu Feng.

Seeing Ao Wuwei walking into the innermost cave, Lu Feng's expression finally showed a trace of solemnity and worry, but things had come to this point, Lu Feng knew that even if he regretted it, it was too late, although all kinds of doubts filled Lu Feng's heart, but if he wanted to solve all the weird things, he had to keep going.

I don't know why, Lu Feng faintly had a thought in his heart, that is, even if he didn't want to practice poison skills, he was afraid that he would not agree, and the whole thing seemed to be doomed from the beginning.

It didn't take long for Ao Wuwei to come out of the hole inside, but this time the blood refining grass in his hand had completely disappeared, and it was replaced by a bowl of scarlet liquid, far away, Lu Feng had already smelled the bloody smell of the red liquid in the bowl.

There was no need to guess that Lu Feng also knew that this bowl of red liquid was the juice ground from the blood refining grass just now.

Seeing that Ao Wuwei was holding a round white stone chip with white light in his right hand, Lu Feng looked at the stone with white light with some doubts: "Master, what is this?"

"This is called Hanyu, you will often use it when you want to practice poison skills in the future, as long as you put it on your chest, it will help you calm your heart, get the effect of temporarily suppressing the poisonous gas and attacking your heart, and you will wear it on your chest later. Ao Wuwei handed the white stone chip to Lu Feng.

As soon as he received it in his hand, Lu Feng felt a cold and biting chill, and only drilled into the palm of his hand, stimulated by the cold jade, and even the lines on the back of Lu Feng's left hand slowly became clear, and there was a bright light.

Feeling the abnormal movement of the lines, Lu Feng was startled, and hurriedly handed the cold jade to his right hand, and after a while, the Yuan Force seal on the back of Lu Feng's left hand slowly faded.

Ao Wuwei also saw this scene, but Ao Wuwei was not too surprised, and said with a hoarse smile: "This piece of 10,000-year-old cold jade is a great treasure, even in the entire Purple Cloud Sect, there is only the piece in your hand, in order to give you the cultivation of poison skills, it is cheap, when you are okay in the future, don't touch that piece of cold jade with your left hand, hang it on your chest, so that it can effectively block the invasion of poison into the heart vein, and ease the impact of the toxin on the heart vein." ”

After listening to Ao Wuwei's words, feeling the cold cold of the cold jade in his right hand, Lu Feng paused slightly, still dragging the silver thread on the cold jade and hanging the cold jade on his chest.

The moment the cold jade touched his chest, Lu Feng felt a surging cold qi surging towards his internal organs through his clothes.

Feeling the biting cold, Lu Feng kept shivering, and it didn't take long for Lu Feng to feel like he had fallen into an ice hole, and even panting was tingling with a hint of coldness.
