The world where Tao Qian is located is called "the land of fate-edict". People believe that this world is blessed by the gods, and there is a "talisman" inheritance, which is regarded as this land carrying the mandate of heaven and edicting all people, so this land is named "edict".

The world is similar to the "round heaven and earth", the sun and the moon move together, and it is one of the three thousand worlds. Roughly divided into four continental blocks.

The north is the birthplace of the talisman, so it is called "ancestor" or "ancestral land". The western desert is mostly the place, and there are many unexplored places, so it is called "Xi" or "Western Desert". The southern mountains are mostly numerous, and there are many sects, because the first sect was established here, so it is called "Xian" or "Nanhua". Oriental commerce is flourishing, bordering the sea, and there are many opportunities, so it is called "Haimao".

Shouyang Mountain is in the middle of the southern land mass, next to the flow of the "Baili River", the Baili River has been flowing eastward, in the easternmost "south corner" bends, mighty to the north, and finally into the land of the Oriental Haimao, and Haimao's mother river "Mi River" converges, and finally into the sea.

And this except Cuo Mountain, although in the north of Shouyang Mountain, but blocked by the Bailuo Mountains, to take a carriage to go, can only go down the Baili River from Shouyang Mountain, in a place called "Baili Plain" downstream, bypassing the mountains, to reach, and vice versa.

Therefore, the journey along the way is not only long, but also difficult and tortuous, which is not enough for outsiders. It can be seen that this Minatang came to the Shouyang Mountain Realm, and it is impossible to be as simple as catching ordinary villagers for experiments, but what is the conspiracy behind this?

Although one question was solved, another question came one after another, Tao Qian couldn't help but feel a headache, and he couldn't figure it out in his heart. So he simply put it down for a moment and looked at the bottle at the end of the table.

Picking up a black bottle, his right hand fanned it slightly, and immediately a rotten smell entered his nasal cavity, Tao Qian frowned, but still insisted on sniffing, trying to distinguish the ingredients.

Unfortunately, since the smell is completely rotten, it is no longer possible to tell what ingredients are inside. Generally speaking, for cultivators, it is necessary to learn to identify plants and medicinal materials, which is a necessary homework to be done in order to mix rune water, except for a very small number of cultivators, who are strong in their own strength and do not need the assistance of rune water, otherwise every practitioner must learn.

Tao Qian is no exception, although the identification of the composition of the rune water can rely on the sense of smell, but it is also for the normal uncorrupted rune water, for the corrupted rune water, it has little effect.

Yes, runic water can deteriorate and rot. For rune water, some are added with medicinal herbs first and then added to the rune, and some are the opposite, but no matter what order, the moment the rune water is blended and formed, it will enter a period of corruption, and the longer the time, the worse the effect, until it finally completely fails.

Among them, temperature, humidity, storage method, etc. will affect the rate of spoilage. Take the spring water as an example. At the beginning of the addition of the talisman, it will enter a one-month decay period, during which it needs to be stored in a cool and normal temperature place, and it must be isolated from contact with the air with something, because the aura in the air will always stimulate the effect of the plant components in the rejuvenation water, and finally reach a critical value, completely evaporating into the air, so the effect will be weakened.

The rune water in the bottle in front of him is already completely corrupted, but the question is, what kind of rune water will be corrupted so quickly, it seems that the rune water blended by this ancient rune requires a lot of materials, and the process is complicated, and from the result of failure, it may be that some ingredients conflict with each other, which accelerates the corruption of rune water.

Tao Qian put down the black bottle and picked up another one, there was no rune water in this bottle, but there was some residue.

The residue is a mixture of red and yellow, and it is all in the form of powder, but if you look closely, some leaf residues remain, which may be that the material was not treated properly, and it is estimated that it was processed later in the experiment.

Looking at it this way, combined with the changes in the handwriting on those papers, it can be seen that the excessive number of failures in the later stage caused the experimenter's mental condition to be very unstable.

Suddenly, Tao Qian's inspiration flashed, could it be a side effect of Fu Shui? Since the blended runic water will cause people to turn into monsters, won't the smell, residue, etc. have the same characteristics, but the effect is strong or weak.

Tao Qian thought of the children of the Tian Da family again, who were also mentally abnormal, and their limbs could not be controlled. Tao Qian grabbed something again, since this talisman water will cause people to turn into monsters, wouldn't the saliva flowing under this monster also have side effects, in this way, it makes sense that the saliva will cause the children of the Tian Da family to have abnormalities!

The doubts that Tao Qian had hidden in his heart for a long time were finally solved, and it seemed that the root of everything was this experiment. Now, as long as you find a way to make this experiment not work, or get rid of the people who conducted the experiment, you can solve those monsters and complete the task.

Thinking of this, Tao Qian put down the bottle, stuffed the three books on the table into the baggage, thought about it, and put the bottle containing the residue into the bag for careful study later. After all, even if this experiment is destroyed, it is only a palliative treatment, and the corresponding antidote must be developed to eradicate the harm caused by this runic water, and these three books and the bottle containing the residue are quite precious research materials.

After packing everything up again, Tao Qian turned around and was about to go out. Suddenly, a voice sounded at the exit.

"Who is it?"

Not good! It's been discovered! Gotta run!

Tao Qian didn't care about being surprised, and hurriedly threw out a fireball talisman and attacked straight to the door of the person who came from the cave.

"It's you!" The one at the entrance of the cave was the tall and thin man among the two black-robed people, that is, the green deputy hall master in the mouths of those minions.

When the Qing deputy hall master walked to the entrance of the cave, he found that the door of the cave was wide open, and he immediately realized that the thief had entered, but the next moment, before he had time to think about it, a fireball came straight to the door in front of him, and he fixed his eyes on it, it was the kid who had escaped, and at the same time he exclaimed in his mouth, he also pinched out the talisman and summoned a shield.

The fireball hit the shield, and the shield body trembled violently, and the next moment it shattered, and the Qing Deputy Hall Master was also knocked out and fell heavily to the ground.

Tao Qian took this opportunity to catch up with the Qing Deputy Hall Master in a big stride, and was about to make another move, but saw the Qing Deputy Hall Master throw something out of his sleeve robe and fly towards him.

Tao Qian twisted his ankle and kicked the ground, his body turned back with one forehead, and the thing flew over his forehead, and Tao Qian realized that it was a thin needle made of talisman paper.

The thin needle brushed over, cut a single hair, and then nailed straight into the earthen wall behind him, and the whole root was submerged, which showed the great strength and sharpness.

There are many kinds of rune paper, the most common is yellow rune paper, which is made of sand wood, soft in texture, easy to write, can carry a large amount of spiritual power, and is not easy to leak ink, and is the most commonly used paper for drawing runes. However, there is also a kind of rune paper, which is different from the former, made of hard ironwood, which has a hard texture and can be transformed into a certain form by drawing runes. However, its biggest disadvantage is that it can not carry much spiritual power, and it is suitable for making amulets, accessories with some special effects such as warming the body, or disposable talisman props, such as the thin needle used by the Qing Deputy Hall Master.

In general, the two kinds of rune paper and yellow rune paper are the mainstream, and the ironwood rune paper is only an auxiliary effect, but if it is used well, it can also be surprisingly successful.

But when Tao Qian barely dodged the talisman needle, the Qing deputy hall master had already gotten up and fled towards the outside of the cave. Tao Qian saw that he was about to lose his target, so he used a magic talisman and quickly chased after him.

For stealth investigations, it is most important to startle snakes. If you let this Qing deputy hall master escape and call for reinforcements, if you don't expose yourself, you will also fall into great danger.

The distance is getting closer and closer, the deputy hall master of Qing has suffered a lot of injuries, his pace is disordered, his qi and blood are empty, and his speed is no longer fast, and Tao Qian also has confidence and certainty in his heart.

But at the moment when he was about to catch up, the Qing Deputy Hall Master disappeared out of thin air.

"What?" Tao Qian hurriedly stopped at the place where the Qing Deputy Hall Master disappeared, a little shocked and dazed, what kind of spell is this, it can disappear out of thin air?

After a closer look, I found that there was a piece of rune paper on the ground, and when I picked it up, it turned out to be a talisman of the mother and child.

This child and mother talisman, there is only one mother talisman, but there can be seven child talismans. Put the mother charm in a safe place, and when you encounter danger, tear open the child charm, and you can teleport to the place where the mother charm is, but there is a distance limit, and the straight-line distance between the mother and the mother is no more than 20 miles at most.

Although it sounds good, many people dislike that the distance between the child and mother charm is too short, like chicken ribs, it is a pity to abandon it, and it is tasteless to eat. Therefore, the demand for this child and mother charm is not large, and the output is naturally not high, but it is expensive.

Tao Qian didn't expect that this deputy hall master would have such a treasure, but after thinking about it, this mother talisman was within a radius of 20 miles, and the deputy hall master of Qing was also injured a lot, and no one would find out for a while, but be careful in everything, in case there is any communication tool, it will be bad.

Thinking of this, Tao Qian rushed out of the cave, bypassing the patrolling guards all the way, and returned to the camp where he set off, preparing to rest for a while before making plans.
