The flying items were held in his hand with a slight coolness, Yan Xu spread out his palm and looked, a rusty black copper piece appeared in front of him, just like the one left by the previous master, but the faintly visible dark engraved pattern was different.

When the black copper piece was turned out from the inheritance of the previous head of Wu, Yan Xu didn't care about it, but just threw it into the head ring, until Deng Yu accidentally found the second black copper piece and triggered the hidden task 'Collect the map' that Yan Xu paid attention to.

Taking out the two black copper pieces before comparison, Yan Xu put the three black copper pieces together, only to see that the blurred pattern engraved on the black copper sheet black light flashed slightly, and the stripes became clear, and it was a hidden map.

Yan Xu frowned and pondered carefully for a moment, but still didn't get a clue, although he was only missing the last fragment of the map, but with the remnants of the three fragments in his hand, he still couldn't tell where the map was referring to the Tianhao Sect, or whether the map was not in the Tianhao Sect.

"You have to find the fourth map fragment, this third black copper piece is all up to luck, if it weren't for the construction of the elixir garden, I don't know what year and month I would know that the black copper piece is buried here."

So far, Yan Xu has received a total of two hidden missions, in addition to this mysterious map fragment, another hidden mission is to refine snake skin in the secret territory of the Blood Crystal Hydra.

Refining snake skin made Yan Xu reborn, not only did his cultivation improve by leaps and bounds to the seventh layer of qi refining, but his physique was greatly improved, although the qualifications of the four pseudo-spiritual roots had not changed, his cultivation speed was not the same, not to mention that he had comprehended the two bloodline supernatural powers.

The huge gain will inevitably mean that the more difficult it is to complete, Yan Xu now recalls the pain he endured when refining the snake skin, and he couldn't help but feel numb in his scalp.

If I repeat it again, I am not sure if I will still succeed, and the pain caused by tearing each cell from the outside in and reorganizing the flesh and blood is engraved into the depths of the soul, which makes people shudder.

It can be seen that this mysterious map fragment will only be more difficult, and after reading the mission description, Yan Xu speculates that after finding the location of the map, the follow-up mission should be triggered.

When the head of Wu was dying, he passed it down very solemnly, Yan Xu didn't care, now it seems that the potential secret behind this map may be related to the Tianhao sect, otherwise as the head of the previous dynasties, he would not have left this thing for no reason.

How to find the clue of the last map fragment, there is no good way in a short time, even if you launch a carpet search by everyone in the sect, you may not be able to find something, and things like Deng Yu's discovery of the second piece of black copper will not always happen.

Yan Xu put away the three pieces of black copper, turned his head to look at the level 1 elixir garden that had been built, and now the most important thing is to develop the sect's foundation in a down-to-earth manner.

A palace gate was built at the entrance of the valley, the blue tiles and red walls were exquisitely shaped, and the three big green characters of 'Elixir Garden' exuded vitality, which made Yan Xu suddenly feel bright.

The red wall extends several miles from the temple gate to both sides, enclosing the south entrance of the valley medicine garden, connecting with the mountains on both sides, and enclosing the entire valley into an independent world.

Yan Xu stepped into the elixir garden and took a deep breath, "The first-level elixir garden comes with a spirit gathering array, absorbing the aura around and within the leylines, and the effect is really extraordinary. Tianhao Sect's aura has always been thin, but it should have reached a level 1 aura concentration here. ”

Continuing to walk into the elixir garden, more than a dozen vacancies in the medicine field are planned in the valley according to the herb planting environment. Except for one or two medicinal fields that can be used immediately, most of the vacancies in the medicinal fields need to be exchanged for spiritual fields and laid before they can be planted with medicinal herb seeds for official use.

"The library can assist disciples to participate in the Taoist method, and various exercise cheats need to be constantly filled for disciples to choose; Although the Spirit Animal Garden can domesticate demon beasts, it must also be carefully raised for advanced growth. Now this elixir garden is even more so, if you want to grow more medicinal herbs, you have to invest more points to expand the medicine field. ”

The exchange system of the head of the sect brings infinite possibilities to Yan Xu and Tianhao Sect, but it is by no means a success, it is like planting a seed, which still needs to be poured by oneself to grow into a towering tree.

The only difference is that it takes hundreds of thousands of generations for others to cultivate a big tree, but the exchange system of the head of the sect has allowed Yan Xu to greatly compress his time, but the effort involved is not a lot.

After inspecting the distribution planning of the medicine fields in the valley, Yan Xu understood the overall layout of the elixir garden. The mountain peaks belong to the yang valley and belong to the yin, but this valley sits in the north and faces south, the sun shines all day long, and the light is sufficient to make up for the lack of yang, which can be said to be yin and yang and full of changes.

Therefore, the growth environment of these more than a dozen medicinal fields outside the valley is suitable for planting most of the sun-loving medicinal materials.

In addition to the valley, this outer garden, the elixir garden relies on the Qinglan Peak mountain wall to the inside, and the natural cave is the inner garden. The inner garden is hidden in the cave, and it is a shady place that does not enter the sun all day long, which is suitable for the growth of herbs that like shade, darkness and moisture.

Walking into the cave, Yan Xu did not feel depressed inside the cave, but found that the concentration of aura was much thicker than outside. Yan Xu carefully investigated the structure of the cave and found that this cave belonged to a living cave, not only with a spring gushing out of groundwater, but also several hidden tunnels connected to the outside world, with air circulation and freshness.

Walking to the deepest part of the cave, Yan Xu's heart moved, and he reached out and twisted an inconspicuous protruding stone on the rock wall, and then with a few clicks, a stone door opened on the rock wall.

After getting the prompt of the exchange system in charge, Yan Xu knew that there was actually a secret room hidden in the cave of the inner garden of the elixir garden.

The secret room is not large, with a cyan boulder standing in the middle, and a turquoise light flashing in the hollow in the middle. This turquoise light was exactly where the Spirit Gathering Array of the Elixir Garden was located, Yan Xu stretched out his hand and gently probed into the array disk, and a stream of information was transmitted to the sea of consciousness.

Receiving the message from the array, Yan Xu looked happy: "I see! The so-called 100 years and 1,000 years are just the names of the medicinal materials that contain medicinal power, and they don't really need thousands of years to grow! ”

The value of the elixir spirit grass is mainly measured by the year and the grade, and the first-grade medicinal materials are only the first-grade after all, no matter how long they are cultivated, and they can only be used to refine the first-grade or second-grade elixir.

The longer the year, the stronger the medicinal power contained, the stronger the medicinal properties of the elixir refined, the higher the rate of becoming a pill, and even the best elixir. In addition, some special alchemy remedies will also have requirements for the year of medicinal materials, such as Zhuji Dan, each flavor of the required medicinal materials is at least 100 years old, and some main medicines are even 1,000 copies.

If you want to enter the road of cultivation, if you don't build a foundation, you can only live for more than a hundred years after all, and there is not much difference in life compared to ordinary mortals.

The vast territory of the Luotian Continent has existed for tens of millions of years, even if the medicinal materials are rich, if you really obtain a hundred years or a thousand years of medicinal materials according to time, no matter how many medicinal materials you have, it will not be enough for so many monks to accumulate and consume them over time, I am afraid that the cultivation inheritance has already been cut off.

Therefore, the year in the Luo Tian Continent was only a unit of measurement for the power of spiritual herbs. If the place where the herb grows is vigorous, it only takes a few months to reach a hundred years of medicinal content. On the contrary, if you grow in a place where the aura is thin, even survival may be a problem.

To Yan Xu's surprise, with the inconspicuous cyan boulder in front of him, as long as the spirit stone was put in to accelerate the operation of the Spirit Gathering Array, the concentration of the spiritual energy of the entire elixir garden would increase several times, thereby greatly shortening the growth cycle of the medicinal materials.

Of course, if you want to obtain high-grade medicinal materials as soon as possible, if you invest in spirit stones of higher grade, the more you will have, in short, it can be understood as converting spirit stones into medicinal materials.

If you just simply replace the spirit stone with ordinary medicinal materials, it is not worth much surprise, after all, you can buy medicinal materials anywhere with spirit stones.

What Yan Xu values the most is that some scarce medicinal materials cannot be bought with spirit stones, otherwise when the auction house takes out the rare elixir, it will not be a bloody battle.

With the help of this special function in the Elixir Garden, as long as the supply of spirit stones is sufficient, it will be possible for Yan Xu to obtain any medicinal materials.
