Xiao Tie saw these changes in his eyes, and he didn't know whether he was happy or melancholy, because he knew that this change was good, but there was still a long way to go from his intended purpose.

In the blink of an eye, a month has passed, from city to city, village by town, Xiao Tie no longer knows how far away he is from the nameless town, he only knows that he has walked far, far away.

Along the way, he has always pursued a low profile, but there has been no change, following the customs, eating, drinking and enjoying, and at the same time, he has not experienced the process of becoming strong from weak.

In a month, he gradually liberated his strength, not the same suppressed strength, and every time he unsealed a part of his strength, it took him a day, or even a few days, to adapt and familiarize himself, and in this way, a month also allowed him to unseal his strength to the level of the late stage of the Xuan level.

After all, the completion of the main quest is only a virtual completion, and before it is really popular, it will be discounted after he submits it.

During this time, the strength of martial arts cannot be improved for the time being, and he can take advantage of this time to complete the side quest step by step, which is also a kind of state of mind experience.

On this day, Xiao Tie climbed a steep mountain.

This mountain peak is deserted, far away from the crowds, towering into the clouds, and the solitary peak is independent, standing out among the mountains, which is extremely peculiar.

Climbing to the top of the mountain, Xiao Tie made a decision.

"Today, let's start preparing poison!"

After a year of accumulation, he became proficient in the ability of the Tongue of God, and initially mastered the role of this ability, and learned to simply configure poison!

Three months of college life, absorbing all kinds of knowledge, confirming each other, so that this ability can be further purified!

And a month's experience is a kind of polishing, until this time, Xiao Tie feels that it is time!

He had already prepared all kinds of materials for the preparation of poisons, and this place was deserted, so he didn't have to worry about being disturbed, and he didn't have to worry about the negative impact of failure, it was the best place and the most suitable time!

To know!

Configuring a real poison is not as easy as you think!

For Xiao Tie!

There are two main problems related to the allocation of poisons: first, the choice of kind, and second, the transmission route of the poison itself!

Only by completing the choices of these two questions can you configure a poison that is truly suitable for your own use!

Types, as the name suggests, can be divided into soul poisons, blood poisons, organ poisons, and aura poisons according to Xiao Tie's exploration, which can affect all aspects of life according to the completely different medicinal properties.

Soul poison, which can weaken the soul, is an evolved version of the neurotoxin, which can not only target the nerves of life, but also affect the soul!

Blood poison, the blood that can corrupt life, this poison may be a little ineffective for most martial artists, but for the congenital strong monster, it has a miraculous effect, the blood is suppressed, then its strength will be greatly weakened!

Aura poison is the power of martial arts that corrupts all life, including demonic beasts and martial artists, and it is also a weakened type of poison, and it is so toxic that it can even turn the cultivation power of a martial artist into nothingness!

Finally, there is organ poison, this poison, the most special, directly affects the organs in the underworld, the pertinence is very obvious, can greatly suppress the life recovery ability of the poisoned, and the blood poison is used together, it is absolutely a perfect match!

As for the nature of transmission, it is easier to understand, any poison has a way of transmission, wound infection, airborne and so on.

These two choices, as long as they are determined, can select the materials and techniques when the poison is finally configured, so as to affect the final poison product.

"There is no problem with the main quest, once submitted, my true strength will definitely not be weaker than 'No. 2', so in terms of the nature of transmission, I can completely choose the poison of the wound infection type, as long as the poison is injected into the opponent's wound, it can work directly, and this effect is also the most direct and fast. ”

"As for toxicity, the situation of 'No. 2' is too special, the speed of vitality recovery is unprecedented, terrifying, blood poison and organ poison are indispensable, it is naturally the first choice to suppress its recovery, but suppression alone is obviously not enough......"

"No life is indispensable to the soul, and the poison of the soul is insoluble and terrifying, and it is the best choice to deal with it......"

The compound type of poison is too complicated, and with Xiao Tie's ability now, it is impossible for Rao to perfectly soften all the poison types together, even if they are barely softened together, the effect will be greatly reduced, not to mention affecting the master of the 'No. 2' Warcraft, even the heaven-level Warcraft is difficult to influence.

Now, he has the most control over the soft kinds, and there are only three poisons, so he has to be selective.

After determining the type of toxin and the route of transmission, Xiao Tie closed his eyes and deduced.

This sitting is three days.

For three days, Xiao Tie continued to deduce all aspects, the selection of medicinal materials, the configuration method used, the proportion, etc., how to achieve his expectations after the poison was dispensed, this is definitely an unimaginable huge project.

Fortunately, Xiao Tie's cultivation has now reached an extremely high level, especially the bonuses of special occupations, which make his mind run far beyond ordinary people, and it is likely that others will need years, or even decades, to do things that are possible in a lifetime, but Xiao Tie can deduce them in a very short time.

Coupled with the special nature of the Tongue of God, he is not afraid of any toxin lower than the level of his Tongue of God, which is an anti-heaven ability, so that Xiao Tie is not afraid of failure at all, so when three days later, after the preliminary deduction of the performance plan, he directly began to configure.

The first configuration, it takes a day and a night.

The poison that is configured, there is a strange fragrance in the dark green, the fragrance floats for a hundred miles, and within a hundred miles, everything is withered and life is extinct!

There is no doubt that this poison is extremely toxic, if a heaven-level martial artist arrives, this strange fragrance alone is enough to kill them on the spot!

However, for Xiao Tie, this is a failure.

"The toxicity is violent, but it does not meet expectations, it can affect the king level at most, and the toxicity is too diffuse......"

Just as Xiao Tie muttered, the poison of this poison was not what he needed at all, the toxicity was too diffuse, and the diffusion meant that the toxicity was not up to standard, and the effect was not satisfactory, it was not the poison he expected to be smeared on the weapon, and it was a failure in all aspects.

Carefully put it into the jade bottle to keep, after all, it is something that he consumes a lot of rare materials to configure, even if it fails, it can't be wasted, although it can't be used on 'No. 2', but it will be used in the depths of the demon cave in the future, it will definitely have a miraculous effect.

After collecting the poison, Xiao Tie continued to deduce, based on this failure, and two days later, he did it again.

The second poison was much better, colorless, tasteless, and non-spreading, and the toxicity was several times more violent than the first one, this poison Xiao Tie dared to be sure, even the emperor-level existence would be poisoned.

However, this is still a failure.

The toxicity is violent, but at most it can only affect the imperial level, and there is still a huge gap with its expectations.

And not only that, the effect of this poison is also unsatisfactory, except for the poison of the soul, the other two effects are basically zero, which is suffocating.

Third, fourth, fifth......

Again and again, the materials prepared were reduced at a speed visible to the naked eye, and the various utensils containing poison were already placed around Xiao Tie's body.

Configuration after configuration, but failure after failure.

Dozens of configurations, none of which satisfied Xiao Tie.

However, Xiao Tie was not in a hurry, but looked forward to it more and more.

Because as time went by, the configuration continued, and he clearly felt that he was getting closer and closer to the goal, and he felt that maybe next time, he could configure the poison he needed!

"In one year, I have accumulated countless experience in concouraging poisons, and three months of college life have taught me a lot of methods and knocks on doors that I didn't know before......

"And now ......"

Looking at the poison that was about to be completed in front of him, he didn't stop moving in his hands, and he controlled the power of martial arts with one hand to drag a variety of individual medicinal powder and juice, and in a flash, he fused these materials one by one, this fusion was handy, like heavenly help, what needs to be done when each material is fused, and what amount is needed, he knows it well!

"Sealing the spirit flower, broken in the cold, burning in the fire, melting in the water, escaping in the soil, born in the god gold, but with the sky zero vine, but with the turbidity tree fruit slurry complement each other, the two fuse, produce a miraculous effect, can be fused with the sky zero vine ......"

"This is the Crossing Grass, born under the seventh layer of the Demon Cave, there is a certain chance of the place where the strong fall, with corpse blood and flesh and bone as nutrients, three flowers bloom, one of which is the elixir, the other is highly toxic, the elixir can be taken to consolidate the Peiyuan, the solid foundation, the poison will inevitably produce hallucinations, before the fusion, you need to dissolve the spirituality, retain the poison, otherwise it cannot be fused with any material, the effect is lost......"

Five, ten, fifteen......

Step by step, methodically, without the slightest pause!

However, this scene is not as easy as it seems, if you do it by another person, you may fail in the second step, you know, this is Xiao Tie's conclusion after trying again and again since this period of time, taking himself as the foundation, and Rao is like this, even Xiao Tie does not dare to have any slack.

The liquid medicine gradually takes shape, the color is constantly changing, white, red, black, green, like a cycle after another, all kinds of colors are appearing and disappearing, and while changing the color, it also represents the fusion of materials again and again, and the properties of the liquid medicine change.

At a certain moment, the liquid medicine emitted a vision, Xiao Tie's heart suddenly appeared, the vision appeared, it was not a good thing, the real top-level poison should be colorless and tasteless!

Fortunately, after another material was added, the vision suddenly disappeared, and he was greatly relieved.

At a certain moment, there was a terrible fluctuation of the liquid medicine, and even Xiao Tie felt a palpitation, this was the conflict of energy of the liquid medicine, and he was about to go berserk, which made Xiao Tie pinch a cold sweat at the same time, and almost threw away the liquid medicine and ran away, it was terrible!

Fortunately, he held back at that time, didn't say a word, and hurriedly incorporated another material according to experience, stabilized it, and solved the crisis!

Fusion again and again, it can be said that it is frightening at any time, and the later it is, the more difficult this fusion is, and the more effort is consumed!

An hour, two hours......

It's like a year!

By the end of the night, there were a total of 444 estimated materials, and it was finally the last minute!

Xiao Tie looked at the medicinal liquid that was about to go to the last step, at this time, the medicinal liquid was translucent silvery-white, flashing with a faint white light, and the liquid medicine was only a drop the size of a thumb, but it was not difficult for him to find that the terrifying power contained in this liquid, if he didn't have the tongue of God, I was afraid that even he would be poisoned by this poison on the spot!

Look at the last material, this is a very toxic metal powder, toxic materials, not only medicinal materials, everything has a certain toxicity, just the size, and this last metal powder is the best among the metal toxic substances!

"With the current situation of the liquid medicine, it has stabilized, and the toxicity has reached the extreme, and this last material ......"

Xiao Tie hesitated a little.

Poison doesn't mean that the more toxic materials you match, the better.

Sometimes one poison can poison the Supreme, but after adding another material, even ordinary people can't poison it.

In the same way, at this time, Xiao Tie himself was not 100% sure that after this toxin metal was added to the venom, it would increase the power of the venom.

After all, at this time, the fusion of four hundred and forty-three toxic substances had reached the extreme of his current deduction, and the four hundred and forty-four was not too sure for him.

Of course, it's not completely uncertain, after all, being able to deduce the four hundred and forty-four toxic substances itself means that he still has certain expectations, and it is precisely because of the deducing performance, after adding this metal material, the venom can reach perfection, and he will take it out, otherwise, what is he doing with this material?

Gritting his teeth, Xiao Tie plans to fight once!

Anyway, this time the venom is already extremely successful, it's a big deal to remember the steps, and try again after failure, but this state is not common, it must be grasped, once successful, it is likely that he will configure an unprecedented poison, which is not to be missed!

After a little thought, he carefully took out a very rare bit of metal powder, and then incorporated it into the liquid little by little......

At the beginning, the liquid medicine did not change and was very stable, but this stability made Xiao Tie frown.

You must know that stability means that there is no change, and there is no change, so the possibility of failure in his attempt this time is very high.

"Is it not enough?"

Thinking about it, he couldn't help but increase the amount and fuse again.

This time, there was finally some change, and there was a wave on top of the liquid like Baoyu, which made Xiao Tie's eyes light up, but he was also more careful!

Because he knows that this will be the most critical time, once he succeeds, he naturally needs not say much, but once he fails, this configuration that he spent his effort on will be directly ruined, even if there are all the previous steps, it is not so easy to configure this liquid medicine without any mistakes again, it takes time and time again to try, and it takes a huge amount of effort and material!

In ten seconds, the color begins to become darker, like mercury!

Twenty seconds, there was originally some metallic venom, but after adding metal powder, it actually became dull, without the slightest smell!

Thirty seconds, suddenly, Xiao Tie stopped!

At the same time!

Venom has changed unimaginably!

The color is completely fixed, but bright silver!

The taste has changed, and it is not the same as the tastelessness that Xiao Tie expected, there is a sweet place permeating, even if he doesn't try it, Xiao Tie also feels a bloody sweetness!

It's done?

Xiao Tie watched in disbelief as this grain shrank again, only a drop of venom the size of a little thumb...... 8910
