In the global desert, I have a spring of spiritual water.

After Hu Changhe left, Chen Chuan immediately opened the book "Elementary Formation Guide". He came to this world as a Life Source Master, but he had no knowledge of formations. There was nothing he could do about it, since his predecessor was a spoiled brat. He didn't have much useful knowledge, but he was proficient in a lot of random techniques.

The only Golden Bell Formation that Chen Chuan knew was a basic formation that came with him as a Life Source Master, like source code implanted in his mind. Therefore, this "Beginner's Guide to Formations" was extremely important to him.

Back in the training room, Chen Chuan began to study the text word by word:

Between heaven and earth, spiritual energy flows, and all things have their order. Array formations are a method that borrows the spiritual energy of heaven and earth, follows the principles of nature, uses runes and energy stones as guides, and an array base as its skeleton, to transform intangible power into tangible ability...

Before obtaining this book, Chen Chuan was essentially holding a powerful weapon but without the instruction manual.

And now we have the instruction manual!

Whether it was due to his improved cultivation or the cheat code he gained after transmigrating, he had an excellent memory, practically photographic, and quickly read through the "Elementary Formation Guide".

This book contains a lot of information, including the basic principles of formations, common operating methods, various practical examples, and methods for breaking formations.

At the end of the book, two formations are also included: the Overturned Water Demon-Slaying Formation and the Ten-Sided Bewitching Formation.

The former is an offensive formation with strong destructive power, while the latter is a defensive formation that can trap people inside, leaving them with no way out.

The book tells us that all formations require materials, especially powerful formations which require a "formation eye". For example, the Overturning Water Demon Extermination Formation requires "water" as its formation eye and must be set up in a place with abundant water, because the offensive methods of this formation are all based on water. If the water supply is insufficient, the power of the formation will be greatly weakened.

The Ten-Sided Bewitching Array requires one or more "Illusion Beads" as array eyes, along with suitable terrain conditions. This echoes the opening of the "Beginner's Guide to Array Formations," which states that the essence of array formations is to follow the principles of nature, and array formations that utilize the advantages of terrain are often more powerful.

Illusionary Beads are considered a rare and precious treasure; they have a chance to drop when defeating hallucinogenic Sand Demons.

Chen Chuan didn't have the Illusion Pearl, and the terrain of Taipingzhuang wasn't very suitable for the Ten-Sided Bewildering Formation, so he didn't need to consider this formation for the time being.

The Overturned Water Demon-Slaying Formation is very suitable. Since Lingquan still has an avatar available, Chen Chuan can summon another avatar and use it as the core of the formation to set up the Overturned Water Demon-Slaying Formation.

Having made up his mind, Chen Chuan put the "Elementary Formation Guide" into his spiritual spring space and walked out of the training room again.

Hu Changhe, on the other hand, reappeared outside the training room once again, much like an NPC.

"Master, the merchant has already left the city."

Hu Changhe immediately led his men to the post station in the village. Merchants from the border region had to stay at the post station when entering the village, and if the person hadn't left, they would most likely be found there. However, Hu Changhe came up empty-handed.

This result was within Chen Chuan's expectations. Last night he had just demonstrated his ability to set up formations as a Life Source Master, and today the "Elementary Formation Guide" appeared in the village, as if it were tailor-made for him.

What a coincidence!

If nothing unexpected happens, someone must have given it to him on purpose.

But the person didn't want to reveal himself, so naturally he couldn't find anyone to sell the books.

In fact, Chen Chuan asked Hu Changhe to find the person in order to verify his guess. If they could find that person, it might really just be a coincidence. It's not impossible for a border merchant to travel all over the country and do long-distance business and accidentally receive a book related to formations.

But after selling the books, the seller disappeared, so the appearance of these books was no coincidence.

However, Chen Chuan was not in a hurry to trace the source of the book at this moment, because it seemed that the other party had good intentions and wanted him to improve his knowledge of formations.

"Come with me to take a look outside the village."

Chen Chuan strode into the courtyard of the government office, intending to go outside the manor to see where he could best set up the Overturned Water Demon-Slaying Formation.

"Master, it's quite dangerous outside the manor at this time. There was a large-scale sand monster attack on the city last night, and we don't know if there will be another one tonight."

"Should I call more people?"

Hu Changhe followed Chen Chuan and asked, "It's You Shi now, and it's already dark. Normally, the gate of the manor closes at Shen Shi Zheng, which is four o'clock in the afternoon."

"Need not."

"Just walk around the city walls."

Chen Chuan waved his hand and called for someone to bring over two Crimson Flame Horses.

The two then rode their fiery red horses straight out of the manor gate. Normally, the manor gate would not open until the next morning, but since the people leaving the manor were Chen Chuan and Hu Changhe, the gatekeepers naturally dared not stop them.

"Old Hu, which gate did the sand monsters usually use when attacking the city?"

Chen Chuan rode on his Crimson Flame Horse, gazing into the distance by the lighthouse's glow.

The Overturned Water Demon Extermination Formation is a powerful formation. In addition to needing a sufficient water source as the core of the formation, it also requires 100 Grade C energy stones. Activating the formation once requires 10,000 Grade D energy stones.

Chen Chuan considered his current resources and realized he could only choose one direction to set up the formation, and could only activate it twice a night.

Each time the Overturned Water Demon-Slaying Formation is activated, it can continuously output power for one hour. In other words, with his current energy stone reserves, the formation can work for four hours.

"The East Gate is exactly the same as last night."

Hu Changhe gave an affirmative answer and then explained, "I heard that there is a large demon's lair to the east of Taiping Village. Most of the sand demons here come from there. Moreover, the terrain of Taiping Village is high in the west and low in the east. There is also the natural barrier of Jiazi Valley to the west. The road leading to the village is relatively narrow. If it were a group of demons like last night, they would have to queue up to pass. These demons are also somewhat intelligent and would not do such a foolish thing."

Chen Chuan really didn't know much about the area around Taipingzhuang, but after hearing what Hu Changhe said, he immediately understood.

Then set up the Overturned Water Demon-Slaying Formation at the East Gate.

Having made his decision, Chen Chuan instructed, "Old Hu, I'm going to set up an array; you help me protect the pass."

After saying that, Chen Chuan jumped off the Crimson Flame Horse and sat cross-legged on the ground.

There was no water source outside the East Gate, so he needed to set up the Spirit Spring clone first. A few breaths later, a water dragon shot into the night sky, and then blessings descended from the dark night sky.

Seeing this scene, even Hu Changhe, who had witnessed four blessings in one day, was shocked again, because this time it was completely different from the previous four times. Before, there was a well as a foundation, but what Chen Chuan did was to "revive" the dried-up well.

This time, what was originally just a wasteland and a compacted dirt road outside the East Gate suddenly became a gurgling spring, as if it had been moved from somewhere else.

Everyone says that life source masters have powerful water control abilities, but Hu Changhe never dreamed that they would be this powerful, able to directly move water from other water sources.

That's incredible!

Meanwhile, the gatekeepers and the demon-suppressing team members patrolling the city walls were excitedly shouting slogans like "May the city lord protect us and bring blessings from heaven."

They were all still immersed in the joy of the blessings bestowed upon them, and did not notice that a gurgling spring had appeared outside the east gate.

With the array's core in place, Chen Chuan began setting up the array according to the methods in the "Beginner's Guide to Array Formations." The void placed the 100 energy stones needed for the array in the places where they should appear.

Rumble!

As the formation was completed, thunder rumbled in the night sky, and the formation patterns spread out in the air like surging rivers, layer upon layer, before slowly descending to the ground.

The next moment, the thunder stopped, the water shimmered, and the clouds surged. A massive water-covering demon-slaying formation, covering the entire East Gate and the city walls, was completed.
