Chapter 49: Exhaustive Enumeration of Mathematical Tools to Break the Formation!

Meanwhile, outside the Green Peak Gorge in the Sunset Cloud Blessed Land.

Xu Zhengyang and Yang Hong, under Tian Xiyue’s grudge, under Ye Mingyu’s admiration, and under the Zhang siblings’ curses—

Were the first to rely on the temporary disguised array flags to walk out of the Green Edge Absolute Shadow Formation.

Fortunately, all three restrictions had been placed outside Green Peak Gorge.

According to Master Xuan Yin’s rules, all who entered the Sunset Cloud Blessed Land were not allowed to kill each other outside the Green Peak Gorge.

Otherwise—

Xu Zhengyang and Yang Hong’s actions this time would surely have made them targets of public condemnation and would have resulted in them being attacked by everyone together!

After leaving the Green Edge Absolute Shadow Formation.

Xu Zhengyang and Yang Hong did not hesitate and plunged straight into the final Mist Shadow Thousand Slaughter Formation.

The Mist Shadow Thousand Slaughter Formation was originally set up by the True Essence Sect to protect the Bodhi Tree.

Precisely because of this—

Even before entering the Sunset Cloud Blessed Land, Xu Zhengyang and Yang Hong had already obtained the method to break the Mist Shadow Thousand Slaughter Formation.

So after entering the formation, they did not bother with the vast white mist ahead and unhesitatingly dashed toward the direction of the life gate.

Xu Zhengyang and Yang Hong had just taken two steps forward—

Suddenly—

Several piercing sounds suddenly came from all directions, attacking Xu Zhengyang and Yang Hong!

“Watch out!”

Xu Zhengyang was the first to react, and immediately deployed the Blackthorn Formation, transforming the Earth Spike Technique into an earthen spike fortress that surrounded and protected himself and Yang Hong!

“Ding!”

“Ding!”

“Ding!”

……

With a series of crisp clangs, Xu Zhengyang realized that it was actually the icicles from the Mist Shadow Thousand Slaughter Formation attacking them!

Yang Hong still hadn’t figured out the situation—

He thought he had taken a wrong step and triggered the killing formation, and with an ashamed expression said to Xu Zhengyang, “Sorry, Senior Brother Xu. I’ll be more careful from now on, and won’t make a single misstep!”

Even before entering the formation, Xu Zhengyang had already calibrated the proportions of the Mist Shadow Thousand Slaughter Formation using the surrounding environment.

Then, using AR vision, he projected the path leading to the life gate directly onto his retina.

Even if Yang Hong might misstep—

There was absolutely no way he himself would misstep!

But just now—

Those icicles had clearly attacked both him and Yang Hong at the same time!

“It’s not your fault.”

Thinking of this, Xu Zhengyang’s tone turned cold, and he said, “Someone has tampered with the Array Disk of the Mist Shadow Thousand Slaughter Formation and shifted the position of the life gate!”

Yang Hong had great trust in Xu Zhengyang.

So he didn’t question Xu Zhengyang’s judgment and quickly asked, “Then what should we do next?”

The Mist Shadow Thousand Slaughter Formation was a composite water-type formation consisting of both an illusion formation and a killing formation.

Because of this—

It was somewhat similar to the Five Elements Maze Formation that the Tianxuan Sect had placed at the outermost boundary.

The place with the most abundant Spiritual Energy was bound to be where the life gate was!

However—

The Mist Shadow Thousand Slaughter Formation not only had an illusion formation, but also a killing formation.

If they relied on the Health Manager’s Spiritual Energy detection function to find the life gate, they would need to constantly trial and error.

Each wrong step—

Would trigger a volley of icicles, severely slowing down the speed of breaking the formation.

If there were ample time—

Xu Zhengyang wouldn’t mind taking it slow and trial-and-error his way through.

But just as Xu Zhengyang left the Green Edge Absolute Shadow Formation, Ye Mingyu of the Diancang Sword Sect was also not far from the finish point.

The moment Xu Zhengyang thought of Ye Mingyu having a small transparent sword that could point out the location of the life gate in the illusion formation, rendering the Mist Shadow Thousand Slaughter Formation ineffective against him—

He knew he couldn't afford to waste too much time here.

【Fortunately, when Master gave me the method to break the Mist Shadow Thousand Slaughter Formation, I also requested the formation diagram along with it.】

Xu Zhengyang sighed in relief, then continued thinking:

【The Mist Shadow Thousand Slaughter Formation has two Array Disks and twenty-four array flags. The core function of the formation is supported by the two Array Disks and sixteen main array flags, which absolutely must not be moved. Because of this— Only eight array flags can be freely repositioned. Eight times eight is sixty-four. Now that I’ve eliminated one incorrect answer, all I need to do next is list out every possible solution. At most, I’ll only need to try eighty-three more times to break the formation successfully!】

With this thought—

Xu Zhengyang already had a strategy in mind, so he said to Yang Hong, “Let’s go, we’ll return the same way first!”

“Alright.”

Yang Hong did not hesitate and immediately agreed.

……

Calculating the arrangement of a formation—

To Xu Zhengyang, it was nothing more than writing out a set of equations and solving them.

In his previous life—

As an electronic hamster, Xu Zhengyang had even installed MATLAB software in his own brain.

MATLAB was an advanced software for numerical and scientific computation, used to solve various mathematical, engineering, and scientific problems.

Because of this—

When Xu Zhengyang laid out the equation sets and imported the problem into MATLAB, before he and Yang Hong even finished retracing their steps—

All eighty-four solutions for the Mist Shadow Thousand Slaughter Formation had already been fully projected on his retina!

【The repositionable array flags of the Mist Shadow Thousand Slaughter Formation were respectively placed in the eight directions of Qian, Kun, Zhen, Xun, Kan, Li, Gen, Dui. These eight flags were quite far apart. Assuming that the one who tampered with the Mist Shadow Thousand Slaughter Formation didn’t dare linger too long and only had time to swap two adjacent array flags...】

Thinking of this—

Xu Zhengyang immediately decided to verify the adjacent and nearby solution permutations first, ordered by difficulty of changing the flags.

After retracing their steps and returning to the entrance of the Mist Shadow Thousand Slaughter Formation—

Xu Zhengyang immediately took out a blank Jade Slip from the Jade Gourd and inscribed four solution sets on it, then handed it to Yang Hong and instructed, “This contains thirty-two new solution methods. Try them one by one in the order I’ve arranged. The moment you’re attacked by icicles— Immediately return the way you came, and try the next solution. Got it?”

“Don’t worry, Senior Brother Xu!”

Yang Hong replied, and then added, “If I make it out successfully, I’ll notify you immediately using a Messaging Talisman!”

“Mm.”

Xu Zhengyang nodded at his words, then said, “No time to waste, let’s start now!”

……

It had to be said—Xu Zhengyang’s deduction was spot-on!

The person who tampered with the formation had indeed done it in secret!

So when Xu Zhengyang verified just the second solution—

He had already found the way out and notified Yang Hong via Messaging Talisman!

After reuniting with Xu Zhengyang, Yang Hong said with heartfelt admiration, “Senior Brother Xu truly lives up to his name! How does your brain even work? You could even calculate this!”

“It wasn’t that hard.”

Xu Zhengyang responded with a faint smile, casually said a few modest words, and then took out another blank Jade Slip.

After recording some instructions on it, he handed it to Yang Hong and instructed:

“Junior Brother Yang, follow the route I’ve marked for you—head to this location, there’s an array flag there. Pull it out, then follow the next route I’ve marked, and place it at this position. After that— Just follow the final route I’ve drawn for you, and you’ll be able to exit the formation directly.”

Although Yang Hong was straightforward—

He immediately understood the purpose behind Xu Zhengyang’s instructions and excitedly nodded repeatedly, saying, “Alright, alright, alright!

I’ll get right on it!”
