Gu Yao Lao Dao almost revealed his plan, and everyone no longer had any doubts. Next, Gu Yao Lao Dao arranged different preparation tasks for several people.

These preparatory tasks are all related to entering the Ancient Demon Tomb to break the ban, and they need to complete it within half a month, otherwise it may affect the smooth progress of this trip.

Several people attached great importance to the search for the inheritance of Panzu was not weaker than Gu Yao Lao Dao, so naturally they didn't have anything to say, and after discussing everything, they said goodbye to Gu Yao Lao Dao and prepared to go.

When a few people left, Wu Yan was the only one left in the cave mansion of Gu Yao Lao Dao.

For all this that happened before, Wu Yan is still in a fog, dazed and confused. Especially about gambling with Chihuo Tianzun on alchemy, Wu Yan heard them mention it several times, but he still didn't understand what was going on.

However, Gu Yao Lao Dao didn't seem to have the interest and time to explain to him, so he threw him a bone book with four Hongmeng characters on it, "Divine Pesticide Codex".

Wu Yan took it blankly, and when he looked at the name on it, he was suddenly shocked, the secret path can't be such a coincidence, right?

He used to be in the Nether Realm, and not long after he first came into contact with alchemy, he learned a lot of alchemy knowledge and insights from a classic book with the same name.

However, Wu Yan naturally understood that the book he had obtained before, which was named "Divine Pesticide Codex", must be completely incomparable to the bone book in front of him.

There may be some connection between the two, but they are definitely not the same.

Sure enough, after handing him this bone book, Gu Yao Lao Dao only left a few words, and took Wu Yan to the previous alchemy hall.

"This bone slip was taken out of the dojo of the Divine Pesticide Venerable back then, and it is the essence of the Divine Pesticide Venerable's lifelong alchemy knowledge. Since you are interested in alchemy, I will send it to you for study, which can be regarded as the end of the cause and effect between you and me. Within ten days, you must thoroughly understand the knowledge of the poison path and refine the detoxification pill of more than six turns. Poor Dao and Chihuo Tianzun bet on alchemy, and with you fighting, Poor Dao is planning to compete with refining the Detoxification Pill. You should understand the importance of this competition."

Wu Yan nodded, and was about to ask a question, but Gu Yao Lao Dao waved his hand and said: "The importance of the Three Realms Dharma is no less than that of the 'Hongmeng Liberation Dan', and the poor Dao must personally preside over it to rest assured." You separate an immortal clone and hand it over to the poor Dao, and you don't have to worry about other things related to the Three Realms Festival, and you can learn alchemy here with peace of mind. The Dan furnace, the materials, and the flames in this are whatever you want, you can use whatever you want, and there is only one requirement for the poor Dao, on the tenth day, I must see you refine the six-turn antidote pill!"

Wu Yan's face immediately showed embarrassment. The elixir below the sixth turn still belongs to the list of elixirs, and the elixirs above the sixth turn belong to the holy pill.

Wu Yan hadn't even refined the real elixir, let alone the holy pill. As for how to refine the Holy Pill, Gu Yao Lao Dao suddenly asked him to refine the Six-Turn Detoxification Pill within ten days, which was too difficult for him!

This was simply the most difficult thing he had encountered since he stepped into the immortal cultivation realm.

However, before he could open his mouth to complain, Gu Yao Lao Dao dropped the last sentence and walked away.

"Divine Pesticide Venerable, it is the Ancient Medicine Dao Great Heavenly Venerable who is as famous as Hongmeng Medicine Venerable, he has a lifetime of alchemy knowledge, if you can't refine the Six Turns Detoxification Pill within ten days, then you don't have to think about alchemy anymore. ”

Wu Yan looked at the disappearing back of Gu Yao's old way, except for a wry smile, he really didn't know how to express his mood at the moment.

Isn't that child's play?

You must know that the importance of gambling on alchemy is undeniable to Gu Yao. If Wu Yan loses, not only will he not be able to make a name for himself in the name of the Red Fire Heavenly Venerable, so as to collect the materials for refining the "Hongmeng Liberation Erdan", but he will also have to lose a Hongmeng holy weapon, and lose his own fame because of it.

It's just that Gu Yao Lao Dao seems to be extremely confident in the "Divine Pesticide Codex" of the Divine Pesticide Venerable, and even so confident that he thinks that with a Wu Yan who has just glimpsed the way in alchemy, cultivated to only the Ancestral Immortal Realm, and only has the Yin and Yang Divine Fire, within ten days, he will be able to defeat a Dan Dao Tianzun who has been famous in the Heavens and Ten Thousand Worlds for tens of thousands of years!

This kind of self-confidence is simply not self-confidence, but madness!

It's just that when Wu Yan's Divine Immortal Sense penetrated into the bones of the "Divine Pesticide Codex", he only looked at it for a moment, but his face showed an extremely shocked expression, and he was even convinced that as long as he learned some of the knowledge in this pharmacopoeia, he could really defeat a Dandao Heavenly Venerable!

In the Three Realms, all the books that can be named "canons" are all books that record the most comprehensive knowledge in some way.

This "Divine Pesticide Codex" is simply an encyclopedia of Dan Dao knowledge, which actually contains any knowledge related to Dan Dao, and is divided into categories, and each category of knowledge has been recorded and explained and analyzed in great detail.

It is no exaggeration to say that with this bone in hand, even ordinary immortals who have no talent in the Dan Dao can become a master in the Dan Dao as long as they study it carefully.

Wu Yan really couldn't imagine why this old Taoist was so generous to him, and actually gave him the pharmacopoeia of the Divine Pesticide Venerable after completing the book!

At this moment, Wu Yan even thought that he was wrong and thought wrong.

It's just that these things were quickly left behind by him. This is clearly not the time to think about these issues. Gu Yao Lao Dao gave him an almost impossible task.

This is his chance, and it may also be his fate, and he must go all out to deal with it!

In the following time, he was completely immersed in the "Divine Pesticide Codex" and couldn't extricate himself!

With the alchemy hall of Gu Yao Lao Tao as the venue for alchemy, and countless kinds of alchemy materials for him to test and practice, for Wu Yan, this alchemy learning experience is simply an unprecedented experience that cannot be described!

Because of the limited requirements of the ancient Yao Dao, Wu Yan put all his energy into the poison path part of the pharmacopoeia, devoted himself to studying the knowledge of the poison path, understanding everything related to poison throughout the ages, and making the most comprehensive preparations for the upcoming detoxification pill refining process.

There is no difference between the bone slip and the ordinary bone slip, when Wu Yan finished reading all the knowledge of the pharmacopoeia poison dao part, the content about this part of the bone slip really disappeared.

Looking at the depths of the Divine Sea, there is a strange divine tree, rooted in the void of the Divine Sea, and every branch and leaf on it records a different kind of poisonous knowledge.

The trees have not yet borne fruit, but in some places small flowers have already bloomed.

Such a bizarre scene does not seem to be unfamiliar to Wu Yan.

A similar divine tree, in Wu Yan's Divine Sea, there is actually another one, which is also rooted in the void of the Divine Sea, but in another corner.

That divine tree is the Witch Dao Divine Tree of the Witch Dao Inheritance obtained by Wu Yan, and although it is now deep-rooted and luxuriant, not even a small flower has appeared.

This means that Wu Yan is above the Witch Dao, and so far there has not been any kind of Great Dao that has cultivated to the extreme and reached the level of blossoming and fruition.

The strange thing is that Wu Yan only obtained the inheritance of the Poison Dao Divine Tree from the "Divine Pesticide Codex", and a few small flowers actually bloomed on it!

It can be seen that Wu Yan does have an extremely amazing talent above the poison path, but he has never examined his talent in this area before, nor has he developed this ability, so it has been hidden.

On the Poison Dao God Tree, there are three small flowers blooming, which are voodoo, love poison, and anti-drug three different poison path flowers.

This means that Wu Yan has already had a breakthrough comprehension on top of these three different poison paths, at least to the level of the Great Sage Law!

In just a few days, there is such an achievement, in addition to Wu Yan's talent on the way to the poison road, and more importantly, thanks to the knowledge of the poison department of the "Divine Pesticide Codex"!

This is the knowledge of the poisonous path summarized by the Divine Pesticide Venerable after tasting the poisonous weeds and poisonous insects and poisonous beasts of the heavens and all the worlds of the Hongmeng World, and experiencing all kinds of poisonous paths himself.

Wu Yan directly absorbed these knowledge systems into his own Divine Sea, so that in just a few days, the Witch Dao Divine Tree was growing in the Divine Sea, if he could no longer comprehend some of the poisonous paths and give birth to the flower of the poisonous path, then it could only be said that he was above the poisonous path, I am afraid that he has no talent.

Four days were spent in Wu Yan's continuous reception and absorption of poison dao knowledge.

The Poison Dao Divine Tree has grown into a towering tree.

If you look closely, you will find that the tree has four thick branches, and on each branch, seven smaller branches are derived, and at the top of these smaller branches, some of them have already bloomed poisonous flowers, while others have only flower bones and have not yet opened.

After counting carefully, there are actually thirty-three branches that can bloom the flower of the Poison Dao on this Poison Dao Divine Tree, of which twenty-eight are the branches of the thinnest branches, four are the four main branches, and one is the top of the entire Poison Dao Divine Tree!

On the four main branches, there are also flower bones born, and even at the top of the poisonous Dao Divine Tree, there is also a flower bone between the virtual and the real, which is being born!

Wu Yan naturally knew very well what such a situation meant.

Basically, he has completely absorbed the knowledge of the poison path, and the next step is to test and confirm the knowledge of the poison path he has learned through continuous refining of the detoxification pill, and comprehend his own poison path!

These blooming poisonous path flowers, as well as the poisonous path flower bones that have not yet bloomed, are just the birth of his absorption and acceptance of the poison path knowledge of the "Divine Pesticide Codex".

If you want this Poison Dao Divine Tree to completely become your own Poison Dao Divine Tree, and if you want to make the Poison Dao Flower on it bloom completely and bear the fruit of the Poison Dao, he naturally needs to thoroughly comprehend the Poison Dao and create his own Poison Dao!

This task is a long way to go, but for Wu Yan, who has stepped into the path, if he wants to realize it, all he needs is the opportunity to continue to explore and understand!

This time to compete with the Red Fire Heavenly Venerable for alchemy, it is obviously the best opportunity!
