Immortality and Cultivation: This old man seeks enlightenment through mere survival.

After taking the rubbing of the jade slip containing "Notes on the Source of the Azure Waves," Lu Zaian returned to the back mountain of the medicinal field.

"This trip has yielded quite a lot: array plates, crane demon blood essence, cultivation techniques..."

Then Lu Zaian spent an afternoon re-sowing the seeds of the Three Mysterious Flowers on the two acres of land.

He then began to study the array plates.

The basic blank array plate of the first-tier low-grade class looks extremely simple and plain.

It doesn't have a complicated structure or fancy decorative patterns; it's just a simple, disc-shaped base.

Similarly, the blank flags have not undergone any unnecessary processing and remain in their most original state.

These seemingly inconspicuous array plates and flags actually conceal hidden secrets.

They all require array masters to use their superb skills and unique methods to carefully outline and draw the array patterns.

And through a series of complex steps, the array gate and the key methods to control the operation of the array are refined.

"Let me think. There aren't many improvements to be made to the spiritual energy in the herb field. With the Flame Spirit Array Flag, we can also isolate the cold poison."

Lu Zaian sat cross-legged by the herb field, playing with the array plate in one hand and pondering while rubbing his chin with the other.

If planting is done solely by manual labor, it requires tireless daily effort to remove pests and weeds.

You also need to cast a spell to water it every three days.

It's just too time-consuming and energy-draining.

Moreover, given my current limited magical power, it would be difficult to apply the Spring Breeze and Rain Technique to all the Three Mysterious Flowers in the entire two acres of land, making it difficult to ensure that the rain and dew are evenly distributed.

Some of the three-flowered plants will wither and die because they don't receive timely watering.

In that case, we might as well come up with a way to create a formation.

It can monitor the presence of pests and weeds in real time and eliminate them as soon as possible.

It must also have the function of evenly distributing rainfall.

Lu Zaian has been personally working on the land for the past month.

Many problems were discovered.

Because the spiritual energy in the medicinal field is so rich, the weed seeds buried in the soil grow very quickly, and if you're not careful, they will compete with the Three Mysterious Flowers for nutrients.

Every now and then pests fly in and gnaw on the petals of the three-petaled flower.

Unfortunately, it's impossible to keep a close eye on the medicinal herb field all the time, and often by the time pests are discovered, the three-flowered herb has already been devoured by insects.

Another example is when Lu Zaian uses the "Spring Breeze and Rain" technique, it's like he's carrying a water vat and pouring water down it as he walks around.

When handled with extreme care, only a thin stream flows from the mouth of the cylinder;

When he lost control of his strength, the water poured out of the cylinder again.

It's impossible to achieve a uniform quantity...

Lu Zaian observed the vast medicinal herb fields outside.

They discovered that the disciples who were cultivating spiritual plants used the unified array of the Spirit Medicine Valley to isolate themselves from the outside world and prevent pests from invading, leaving only the array gate for the flow of spiritual energy.

However, this will result in a slightly lower concentration of spiritual energy.

However, it ensures that the plants in the field will not be eaten by pests.

As for casting spells to rain down spiritual rain, that's not a problem for those disciples with powerful magic.

Is the distribution of spiritual rain uneven?

If the quality is insufficient, then make up for it with quantity.

Those experienced disciples of spirit plant masters, after long periods of training in casting spells to bring rain, had long since mastered this skill.

They can even cast spells continuously for up to half an hour or even an hour!

Wherever there is a water shortage, we irrigate that place.

Ensure that every corner receives ample moisture.

In this way, all places are filled with rainwater, so there is no such thing as uneven distribution...

Therefore, Lu Zaian's thoughts gradually became clear.

First, my magical power is too weak to continuously cast spells to bring rain.

A formation that can automatically send down spiritual rain should be created instead, and the rain should be distributed absolutely evenly.

By using array patterns to fix and transmit spiritual energy, one can not only free up their hands but also save mana.

"Using the 'Spirit Rain Array Pattern' as the foundation to control rainfall, and the 'Spirit Return Array Pattern' as an auxiliary to reduce losses..."

Secondly, you need to constantly monitor for the appearance of weeds and pests and remove them as soon as possible.

"Hiss...this is a bit difficult."

"However, according to the general principles of array formation, everything has patterns, attributes, and aura."

If I only plant the Three Mysterious Flowers, I can record their patterns, attributes, and aura into the 'Spirit Appraisal Array Pattern'.

This way, if other patterns or scents are detected, it indicates the presence of weeds or pests.

Lu Zaian continued to ponder.

"After being identified and locked by the 'Spirit Detection Array Pattern,' it becomes a lethal array pattern."

In order not to damage the Three Mysterious Flowers, neither linear bullet-type nor wide-range attack patterns are advisable.

This allows for the addition of a gentler 'Thousand Spirit Silk Array Pattern'.

It can conjure up fine, hair-like spiritual threads that bypass the Three Mysterious Flowers, thus wiping out weeds and pests…

Lu Zaian let out a long breath.

After brainstorming, the composition of this first-tier low-grade formation was finally determined.

The Spirit Rain Array Pattern forms the foundation, the Spirit Return Array Pattern assists, the Spirit Observation Array Pattern controls the overall situation, and the Thousand Spirit Silk Array Pattern delivers targeted kills.

perfect!

If one were to unfold and deduce the principles of formations, one would find patterns in everything.

The corresponding array patterns are virtually endless.

Lu Zaian has only memorized a few hundred commonly used array patterns so far, which is enough.

The next step is to refine the array patterns and inscribe them into the array plates and array flags.

Each of the spirit rain array patterns was as small as an ant, and the entire array was designed to cover the two-acre medicinal field.

At least a thousand spirit rain array patterns must be engraved on the array plates and array flags.

"Come on, big project."

Lu Zai Ning focused his mind and spirit, abandoning all distracting thoughts.

Close your eyes and clearly visualize the image of the Spirit Rain Array in your mind.

Lu Zaian simply pointed his right hand together, and magical power flowed from his fingertips like a gentle stream.

Intertwined and entwined in mid-air, gradually forming a twisted pattern of light.

The light pattern resembled a nimble fish, swimming through the air.

Upon closer inspection, it resembles a pictograph for the character "雨" (rain).

But it's not exactly the same; it's more like an ancient and mysterious pattern.

It seems to contain the most basic power of heaven and earth and the way of nature, inspiring awe.

"go with!"

With a flick of his finger, Lu Zaian sent the spirit rain array pattern into the array plate as if summoned.

In an instant, the entire array plate emitted a slight buzzing sound.

The previously dull and lifeless trading screen suddenly lit up with a faint glimmer of light.

These rays of light converged at the center of the array plate, forming a small point of light, like the most dazzling star in the night sky.

Although this point of light was tiny, it was indeed a good start, laying the foundation for the core of the entire formation.

"continue……"

Once the entire array plate lights up and all the endpoints are connected into a complete line, Lu Zaian will have completed more than half of the task.

An hour later.

"Click..."

A crisp sound was heard.

Lu Zaian's face darkened, looking extremely unpleasant.

Suddenly, he noticed a crack in the array plate he was holding tightly in his hand!
