Although there is not much firewood needed on weekdays, it is also very capable of chopping firewood with such a heavy machete, fortunately, Zhang Tianduo has learned some methods of using internal strength, although the chopping is sweaty and messy, but he finally barely completed the task.

After the wood-chopping work was finished, Zhang Tianduo was almost collapsed, he lay on the stone table in the pavilion weakly to rest, only to feel that his arms were sore, and there was an indescribable discomfort all over his body, and his heart was even more nauseous.

At this time, it was almost dusk, and the cultivation to be done today had not yet been completed, and Zhang Tianduo couldn't raise half of his strength in several attempts, and even the "Clear Breath Decision" couldn't eliminate this fatigue.

At dinner, Li Xiang came to greet Zhang Tianduo for dinner, but found Zhang Tianduo lying on the stone table and falling asleep.

By the time he woke up, it was midnight.

His body moved slightly, Zhang Tianduo couldn't help but let out a ** sound, and the soreness that penetrated deep into the bone marrow made him almost crazy.

After struggling for a long time, Zhang Tianduo finally reluctantly got up and walked out of the room.

He stumbled into the kitchen, and soon found the food left by Li Xiang, and he gobbled it up for a while, and after a while, he burped contentedly and sat on the kitchen threshold to rest.

I don't know how long it took, Zhang Tianduo got up and came to the courtyard, tried to move a few times, and found that his strength had recovered a lot.

He lifted his spirits, broke off his drink, and practiced.

Fu Bowen and Li Xiang's house was lit up almost at the same time, and the two walked out with oil lamps, and when they saw Zhang Tianduo who was practicing in the courtyard, the two couldn't help but glance at each other, and after showing a knowing smile, the master and apprentice returned to the house and ignored Zhang Tianduo no longer heeded.

This night, Zhang Tian, who had finished practicing, returned to the house and lay down, which was the most fragrant sleep he slept after coming to Xieyunzhuang.

Three months later.

Zhang Tianduo has been accustomed to the daily heavy practice, Yizhuang all kinds of things he also basically mastered, sometimes Fu Bowen is not there, he can even handle the mortuary and claim and other affairs, in these three months, Zhang Tianduo has also seen other corpse chasers, and also with some of the disciples of the corpse chasers to fight, of course, Zhang Tianduo has not been able to win so far, but he is no longer as miserable as three months ago, sometimes he can even force the opponent to go all out.

After three months of penance, Zhang Tianduo has achieved a certain amount of internal strength, and the heavy work that can only be completed in one day can be completed in only two hours, but a month ago, Fu Bowen added a new cultivation task to him, which made his daily practice still urgent and hard.

This new spiritual task is alchemy.

It wasn't until Fu Bowen gave a new cultivation task that Zhang Tianduo knew that there was originally a dark room in Xieyunzhuang, which was located behind the kitchen, and there were two secret passages, one leading to Fu Bowen's room and the other leading to the kitchen, which was extremely hidden.

The dark room was full of medicine refining tools and all kinds of strange flowers and plants that could not be named, as well as some animal corpses and medicinal scattered stone powder, and the most jaw-dropping thing for Zhang Tianduo was that some disgusting and terrifying-looking strange insects were cultivated in the dark room.

Later, Zhang Tianduo learned that these strange insects are called "Gu worms", which are the key to the Miao black witch's Gu control, and also the key to the embalming of some corpse chasers.

Fu Bowen asked Zhang Tianduo to learn alchemy, which also shows that Zhang Tianduo officially stepped into this mysterious industry, but there are thousands of methods of alchemy, and it is extremely hard to learn, Zhang Tianduo has to learn how to distinguish various flowers and plants and stone insects, but also has to learn how to cultivate and prepare, and finally learn alchemy and usage.

With great curiosity and interest, Zhang Tianduo read the hand-copied secret book given to him by Fu Bowen whenever he had time, which recorded the medicinal properties and preparation methods of various flowers, plants and stone insects, but a month had passed, but Zhang Tianduo only knew one or two of them, and he was still 108,000 miles away from truly mastering the alchemy method.

Although the contents of the manuscript were obscure, Zhang Tianduo was also greatly shocked by the painstaking reading of the month, from which he not only understood how the corpse chasers could drive the dead corpses, but also understood how terrible the bewitching flowers and plants in the backyard were.

For example, there is a plant called "ground ghost grass" in the backyard, this plant resembles a mimosa, purple all over, at first glance there is nothing strange, but the toxicity of this plant is extremely terrible, if one of these plants is crushed and thrown in the well, the poison will spread to the underground water veins in that place, and the drinker will lose consciousness at least the five senses, or paralyzed the whole body.

For example, there is a plant called "impermanence flower" in it, this plant resembles a peony, so it is also called "ghost peony", this flower only blooms two flowers in its life, one is white, one is black, the white one can refine the antiseptic formula, the black one is extremely poisonous, if the juice is fed with a hidden weapon, the body skin of the middle person will turn from yellow to gray, and then from gray to black, and finally the seven orifices bleed and died in pain, and the whole body was black when he died, just like the black impermanence of the underworld.

In addition, other plants are also more or less highly poisonous, almost every one of them can kill people, and the least toxic one can also paralyze people, when Zhang Tianduo learned about this, he couldn't help but break out in a cold sweat, secretly glad that he didn't touch those flowers and plants when he entered the backyard twice, otherwise he didn't know how he died.

However, he always felt that Fu Bowen's refusal to let him enter the backyard had something to do with the mysterious female thief, and these poisonous flowers and plants were only one of the reasons.

Although these strange flowers and plants are highly toxic, if they know how to prepare and refine, they are also antiseptic elixirs, and even some good formulas can remove their toxicity and turn them into elixirs that bring the dead back to life.

There are three parts of the manuscript secret book given by Fu Bowen, the first part is the record of various strange flowers and plants, the second part is the record of Gu worms, and the third part is the preparation, refining and usage, and Zhang Tianduo is most interested in the second part of Gu worms.

According to the secret book, there are many ways to use Gu worms, and the poison is also different, such as "Heart-Destroying Gu", "Seven Days Gu", "Love Gu", "Ecstasy Gu", etc., etc., eight or nine times out of ten are Gu methods to harm people, and only a very small part is related to driving corpses.

The Gu worms that can make dead corpses move contained in the secret book are called "Walking Corpse Gu", which is composed of three Gu worms: "Qinggu Gu", "Baigu Gu" and "Blood Gu Gu", which is the three corpses and nine insects mentioned by Taoists!

It's just that Taoism regards the three corpses and nine insects as a scourge, representing the three delusions of ignorance, greed, and hatred, and there is also a saying that the three corpses are the guardian gods, residing in the human body, instigating the host to think about evil, but complaining to the heavenly court behind his back, making it difficult for the cultivator to achieve the right result.

"Baigu Gu" is located in the human abdomen, the main control body, after planting into the corpse, it can restore part of the deceased's mobility, this Gu palm, whether the corpse can act effectively or not, all depends on this Gu.

"Blood Gu Gu" is located in the human foot, the main control of the soul, after planting into the corpse can ensure that the body does not decay, in addition to the Dao realm and after the death of the person, Qinggu and Baigu will be self-forming, only the blood Gu is still attached to the body of the deceased, absorbing the three souls and seven spirits of the deceased, and the corpse is corrupted and turned into a ghost, which is particularly important because of this Gu, if this Gu is missing, the soul of the deceased will not be able to return to the hometown with him, and the corpse is very easy to get out of control and become a scourge.

In addition, there are several secret methods that can also drive away dead corpses, but the methods are not separated from the sect, although the means are different, the essence is not different, and the secret book only mentions it slightly, and does not add detailed notes.

The cultivation of "Walking Corpse Gu" is quite difficult, the three Gu have a total of nine hundred and eighty-one merits, all of which are indispensable, especially the "Blood Gu Gu" is the most, its main formula "blood bacteria" is extremely difficult to make, the original body of "blood bacteria" is the general pig blood, when the pig blood is not dry, add a variety of exotic flowers and plants to concoct, and place it in a cold place for seven days and seven nights, if it succeeds, it will grow hair-like blood-red mycelium, these hyphae are "blood bacteria", put these "blood bacteria" on the fresh meat, and soon form some green liquid, and plant these green liquids into the corpse, It will form a "Blood Gu Gu", which is difficult because the success rate of mycelium is extremely low, even Fu Bowen, who has been modulated for decades, has only a success rate of one percent.
