WTF, The Centuries-Old Ancestor In Our Family Take Concubine Again!

Chapter 52 - Great Void Sword Formation

“My dear, I have reached the eighth stage of foundation establishment,” Su Yun said to Li Su.

Before heading to the killing formation, Li Su visited the Flying Immortal Sect. He received news that Su Yun had finally come out of seclusion. Li Su was delighted to see that Su Yun had advanced to the late stage of the foundation establishment. Not only that, but she had also broken through to the eighth level of foundation building in one go.

Her seclusion this time had yielded significant results. With the nourishment of love, Su Yun’s progress was much faster than before. At this rate, Su Yun wouldn’t take many more decades to break through to the Golden Core stage. It might not even take that long.

With the thousand years of formation experience, Li Su could allocate the remaining experience to alchemy and create some useful pills for Su Yun to consume.

The Flying Immortal Sect possessed many alchemy recipes, such as the Qingyang Pill and Guiyuan Pill, which were beneficial for the mid-to-late stages of the Golden Core.

Many alchemists in the sect couldn’t produce them, but Li Su could. He could easily refine the recipe and the appropriate medicinal herbs as long as he had the recipe and appropriate medicinal herbs. The sect had some rare medicinal herbs, which could be used to refine certain elixirs that even the alchemists in the sect couldn’t make. So, it was the perfect opportunity to utilize those herbs.

Li Su spent several days with Su Yun in her cave. This time, Li Su advised Su Yun to take precautions and avoid getting pregnant again.

For Su Yun, focusing on cultivation and advancing to the Golden Core stage as soon as possible was the priority. After spending time with Su Yun, Li Su went to the back mountain and discovered that the Sect Leader was still in seclusion. Thus, Li Su proceeded alone to the Black Wood Forest.

After more than ten hours, Li Su arrived at the underground killing formation. With a thousand years of formation experience and his previous research on the formation, it appeared different to him this time.

One thousand years of formation experience should be sufficient, Li Su thought.

It was enough, and he didn’t add any more experience. Instead, he began studying the formation.

“The eyes,” Li Su identified the location of one formation eye.

There was more than one eye in this killing formation. He focused his gaze there. He naturally wouldn’t destroy the formation eye. It was not that easy to break. If it was destroyed, there would be a loophole in this killing formation, and the demon cultivator inside might exploit this loophole to escape.

Even with the threat from the Heavenly Demon Palace, Li Su was unwilling to collaborate with this individual. Cooperating with demonic practitioners was as dangerous as trying to get skin from a tiger.

This person might possess the Nascent Soul stage cultivation. Releasing him would make him change his mind immediately. Li Su wouldn’t be able to handle him. Therefore, Li Su’s initial plan was to eliminate this person.

As for the Heavenly Demon Palace, it depended on when they decided to strike. Even if the Holy Maiden of the Heavenly Demon Palace reached the Nascent Soul stage and came to attack with great force in a few years, and the sect leader hadn’t reached that stage yet, Li Su would have a way to deal with it as long as he could set up this killing formation.

If used properly and the opponent was lured into the killing formation, their threat would be significantly reduced.

“There’s a gap here.” After studying the killing formation outside for several days, Li Su entered the cave.

Anything that entered this cave would be attacked, but Li Su was not attacked this time. He found a deliberate gap between the killing formation and the cave’s stone wall.

It is possible that the expert who sets up the killing array intentionally leaves it to give future generations a chance to crack it and deal with the magician, Li Su thought about this possibility.

Thinking of this, he followed the gap and soon reached the depths of the cave. Inside, it still appeared empty, and even his divine sense couldn’t detect anything. Li Su continued studying there for a long time. Then, he took a few steps toward the center of the cave. No swords attacked him. Li Su stopped and continued his investigation.

After constant research, walking, and stopping for a month, Li Su finally reached the cave’s center and took another step. In the next second, he disappeared from that spot. When he reappeared, he found himself in another space, still within the cave and the killing array’s control area.

Li Su saw two skeletons on the ground and an array of plates surrounded by many formation flags. These flags seemed to be the energy source for the array. There was also an inner formation that appeared to be drawing the earth’s energy to provide a continuous power source for the array.

Many spiritual stones were used here, but most of them had been consumed over the years. After so many years, a substantial amount had been depleted.

“The place where this killing array is set up is ultimately not ideal. If the demon cultivator becomes aware of the truth, he can use some means to continuously weaken the killing array, and it won’t be able to trap him for too long,” Li Su thought.

This killing array was very formidable, and the demon cultivator might not dare to attempt to break it easily. Alternatively, the demon cultivator possessed some special treasure that could only help him protect himself within the killing array, and he might not have many other means. If that was the case, the demon cultivator was probably not in good shape after encountering this killing array.

Two skeletons indicated that two people joined forces to deal with the demon cultivator. Li Su didn’t immediately touch the array plate but searched beside the two skeletons. Soon, he found a piece of paper with two storage bags. The paper was filled with densely written words. After a few minutes, Li Su finished reading the words.

“This guy is indeed a demon cultivator in the Nascent Soul stage, and he’s at the mid-stage Nascent Soul level,” Li Su thought.

The difference between the mid-stage Nascent Soul and the early stage was immense, similar to the gap between the early and mid-stage of the Golden Core. Even two or three early-stage Nascent Soul cultivators cooperating might not match a mid-stage Nascent Soul cultivator.

These two skeletons consisted of a Golden Core stage formation master and a strong cultivator at the early stage of the Nascent Soul. A cultivator’s own cultivation level was crucial, but it didn’t equate to their proficiency in formations.

Similarly, this applied to alchemists as well. A Golden Core stage alchemist could already refine the Golden Core stage pills. Their cultivation level should not be too low. Otherwise, their lifespan would not be long, and their formation mastery would not improve.

This Golden Core stage formation master was indeed a master of formations and quite renowned. The two of them teamed up and ambushed a team from the Demon Sect, even preventing the mid-stage Nascent Soul demon cultivator from escaping the killing formation they set up.

However, they eventually attracted the pursuit of this mid-stage Nascent Soul demon cultivator after snatching the Holy Order that the team was carrying. After almost getting caught, they found this cave, and the mid-stage Nascent Soul demon cultivator successfully tracked them using evil methods. A fierce battle erupted, and this massive cave deep underground was formed during that fight.

The early-stage Nascent Soul cultivator was no match for the demon cultivator, but fortunately, the formation master set up the killing array. Nonetheless, both of them were already under the control of the demon cultivator. The demon cultivator was extremely fierce, using all his means to resist the killing array.

The formation master and the early-stage Nascent Soul cultivator had a chance to escape the killing array. Still, they hesitated because the formidable demon cultivator might break free from the killing array if they escaped. So, they were left with no choice but to stay here.

The formation master presided over the killing formation, and the cultivator in the early stage of Nascent Soul had no choice but to engage in battle because this demon cultivator was exceedingly powerful and possessed numerous treasures that rendered the killing formation ineffective against him.

The demon cultivator also sustained severe damage as their injuries worsened, but he protected himself using a unique treasure. At this critical moment, the two of them were nearly defeated.

The demon cultivator attacked their souls, making it futile for them to escape or attempt to use secret methods to possess other bodies. On his deathbed, the Array Master recorded these events. This was the consequence of their actions.

As for how the holy decree ended up in the hands of the demon cultivator, it was not written on paper.

Perhaps during the most intense battle, the two used the holy decree to distract the demon cultivator and inflict heavy damage upon him.

There was a possibility that with their lives hanging by a thread, the importance of the holy decree diminished. After reading it, Li Su kept the paper and then picked up two storage bags, emptying their contents.

One of the bags belonged to the formation master, containing various colored formation flags and materials for arranging formations. But Li Su’s attention was drawn to a rectangular piece of jade.

On the jade stone, there were four words, “Great Diffraction Sword Formation.”

This is the one, Li Su thought and smiled.

The Great Diffraction Sword Formation was the killing formation. This was incredibly potent and consisted of multiple layers.

The Array Master set up the fourth layer of the Great Diffraction Sword Formation, enough to deal with cultivators in the mid-stage of Nascent Soul.

However, arranging this sword formation was no easy task. Even gathering the necessary materials for the formation flags was challenging. For example, the array flags could not be casually refined and require specific materials.

The ancient-looking long swords were also self-crafted after collecting the necessary materials. To reach a level capable of handling the Nascent Soul stage, the grade requirements for those long swords were quite high.

The Array Master spent many years acquiring the necessary items with the help of Nascent Soul stage cultivators. Now, all these materials could be in Li Su’s possession.

But first, he needed to deal with the demon cultivator inside the formation.

(ED Note: A “killing formation” is a strategic arrangement of magical or spiritual elements used to trap, weaken, or eliminate enemies in battles or conflicts.)
