In Panjiayuan, the first thing they did was trick Lao Hu into going tomb raiding.

Wu Xie found his neck to be ice-cold.

Finished!

The crested snake had already coiled around his neck, and its crested head was held high.

Wu Xie felt an unprecedented despair: "Am I going to die here?"

At that moment, Wu Xie seemed to see Death waving at him.

Just as Wu Xie was frozen in place, unable to make any move or utter a sound, and was about to be killed by the crested snake, he heard a whooshing sound in his ear.

With a soft thud, a chill ran down my neck before disappearing.

The fiery red crested snake had been cut in two.

Wu Xie turned around and saw that the Crimson Cloud Sword had returned to Su Mo's hand. He breathed a sigh of relief, still feeling a chill when he thought about what had just happened.

"Master Su, you saved me again."

Wu Xie was completely limp and powerless, leaning against the wall, too afraid to approach the two sections of snake.

Su Mo said, "Slow down, crawl over slowly!"

Wu Xie nodded and crept stealthily toward Su Mo. The three of them joined together, one in front and two behind, and slowly crawled along.

About half an hour later, they reached the end of the chain.

To Wu Xie and Xiao Hua's astonishment, the end of the chain was connected to a circular object, seemingly made of a huge rock, with one end of the chain embedded inside.

What does this mean?

Wu Xie reached out to try to turn it, but quickly realized that one person's strength was not enough to move it. "I think this is part of the mechanism. In addition to connecting to the iron millstone, it also controls other mechanisms."

Xie Xiaohua said, "Isn't this the control room?"

Wu Xie nodded, "That makes sense!"

Su Mo stepped forward for a closer look and discovered that it was not made of rock, but of bronze.

Remembering its purpose, Su Mo blurted out, "Bronze Code Module!"

Wu Xie and Xie Xiaohua also sighed, "That's right, only bronze can maintain such integrity and stability."

"Back in the Qinling Mountains, that bronze tree was thousands of years old, and it can still be used for sacrificial rites..."

Xiao Hua chuckled, "No wonder I found it so abrupt. I've seen Yangshi Lei's work and memorized it all, but this thing wasn't designed by Yangshi Lei at all!"

Su Mo nodded silently, "Because this was designed by the Zhang family, which is why the Zhang Family Ancient Building has remained safe despite being moved so many times!"

"No matter what dynasty it is or where it is built, as long as the modules are in the hands of the Zhang family, they will definitely be safe!"

Xiaohua seemed to understand, but not quite. "It's like not changing the lock, but still having the key in your own hand!"

Su Mo stepped forward and reached out to pull him.

The iron chain swayed slightly, but the bronze encryption module remained completely still.

Su Mo looked down and noticed that there were many small iron chains in the holes where the iron chains were on the bronze surface.

"Wait... Master Su, I know the principle behind this!"

Wu Xie stopped Su Mo.

Su Mo stopped and turned to look at Wu Xie.

Wu Xie said, "I've seen many of these kinds of mechanisms in my grandfather's notes before. There are only two principles behind them: one is that if you unlock the mechanism correctly, you will be rewarded, and if you do it wrong, you will be punished."

After hearing this, Xie Xiaohua couldn't help but laugh. "Isn't this just like an ATM? If you enter the correct PIN but the wrong amount of money is dispensed, it swallows your card."

Chapter 457: The Shadow of Banna

After hearing this, Xie Xiaohua couldn't help but laugh. "Isn't this just like an ATM? If you enter the correct PIN but the wrong amount of money is dispensed, it swallows your card."

Wu Xie said: "Correct answer!"

Su Mo took a step back. "Young man, why don't you give it a try..."

At this moment, Su Mo suddenly remembered that in the original drama, Wu Xie played a significant role in solving the mystery of the bronze lock of Mount Siguniang.

Since that's the case, Su Mo simply let Wu Xie handle it.

Being able to slack off sometimes is a form of growth for Wu Xie.

"..."

Wu Xie was stunned for a moment.

Then, Su Mo gave a simple analysis, "Look, there are five thin iron chains in total. These are the coded numbers. Calculate how many possible combinations there are..."

Wu Xie smiled wryly, "Master Su, according to the arrangement, there are 120 possibilities. You should know how to solve it. Why don't you do it?"

Wu Xie hesitated, "Master Su, I know these little mechanisms are no problem for you. If I were to do them, it would take me quite a while..."

Su Mo scolded him harshly, "Just do it! What are you dawdling about?"

Having finally seized the opportunity to openly belittle Wu Xie, Xie Xiaohua, taking advantage of the situation, immediately bullied him, saying, "Wu Xie, don't act like a woman..."

Wu Xie: "..."

Good heavens, these two, master and apprentice, are ganging up on people!

Wu Xie felt bitter inside, but forced a smile, "I...I'll give it a try..."

As he spoke, Wu Xie came forward, with Su Mo and Xie Xiaohua on either side of him, assisting him.

Looking at the bronze lock, Wu Xie's mind raced. He said, "I need to follow my grandfather's method, first numbering these thin iron chains sequentially, then disconnecting these chains from the reward and punishment mechanism behind the wall, and making sure to mark the ends of the broken chains..."

"If we keep trying this, pressing the sequence in which all the thin chains are pulled, we'll eventually find the correct password. This is the most conservative method of cracking the code!"

Su Mo nodded, reached out and sawed off the chain, quickly made the corresponding numbers, and then he and Wu Xie pulled the thick iron chain while Xiao Hua recorded the movements.

After trying this for a long time and almost every possible sequence, they finally discovered that the thin iron chain had a different number.

Wu Xie: "Now, reconnect the thin iron chains and repeat the process in the order we derived. Only then will we truly have the password!"

"Act immediately!"

Xie Xiaohua rubbed her hands together, already getting impatient with him.

Su Mo interrupted them in time, "Wait a minute, Xiao Hua and I will pull from here, Wu Xie, you go up..."

"There will be a password on the wall above. Write it down and take a picture of it..."

"By the way, you must pay attention to one thing: you must check if there are any stones or other obstacles blocking the exit of the cipher plate, preventing it from exiting..."

In the original series, the reason why Zhang Qiling, Huo Xiangu, and others had an accident at the Zhang Family Ancient Building was because Wu Xie and Xiao Hua caused a password error at Mount Siguniang.

The password was not displayed because a small pebble was blocking the keypad in one of the grooves.

After that, Xiao Hua and Wu Xie sent the wrong password to the Zhang Family Ancient Building.

This was a fatal mistake!

The incorrect password provided by Wu Xie caused the path taken by Zhang Qiling and his companions to change, leading them down a fatal and wrong route.

Su Mo's appearance at Mount Siguniang, and the emphasis she placed on it this time, was to prevent Wu Xie from repeating the same mistakes.

"I understand, I will definitely watch it carefully."

Su Mo didn't say much along the way, and Wu Xie knew that Su Mo's emphasis at this moment must mean it was an important point.

Wu Xie nodded heavily, then flipped over and climbed over.

After going up, Su Mo and Xiao Hua continued to pull the iron chain to record the password.

"Shh!"

Shortly after Wu Xie went up, a "haired man" silently approached Xiao Hua and Su Mo.

"Master, be careful!"

Xiao Hua felt a chill on the back of her neck and immediately shouted.

As an Earth Immortal, Su Mo possessed extremely keen senses. When the "haired man" appeared, he suddenly raised his right foot. This was almost an instinctive action, a completely natural reaction.

However, this "haired man" was not only extremely fast, but also quite skilled. No one knew how he moved, but he dodged Su Mo's attack in the blink of an eye.

Jie Xiaohua exclaimed in surprise, "Master, could it be Hei Yanjing? Hei Xiazi has been missing for a long time, maybe this 'haired man' in front of us is him!"

Su Mo knew his apprentice was worried about Black Glasses' safety, but he knew that this "haired man" was definitely not Black Glasses.

Having raided tombs for so many years, Su Mo still has this much insight.

Su Mo shook his head, "It can't be him, Xiao Hua, you continue, I'll go and deal with this thing!"

As he spoke, Su Mo slowly walked to the opposite side of the "haired man," looking at it with great interest, his vast and boundless aura rising steadily.

Soon, an overwhelming pressure surged directly towards the "haired man" on the other side.

The "haired man" seemed startled and suddenly took a step back.

However, Su Mo did not give it a chance to escape. He stepped forward, quickly grabbed the "hair man's" wrist, pulled it hard, dragged it to the ground, and threw it aside.

Su Mo's movements were forceful, and the "haired man" was thrown around, completely disoriented and seeing stars. Just as it was about to fight back, Su Mo clenched his fist and punched it in the head.

A sonic boom roared in!

puff!

The "haired man's" head exploded like a watermelon.

"..."

Su Mo: "Pathetic..."

Xiao Hua turned around and saw that Su Mo had already dealt with it. He couldn't help but click his tongue in amazement: "Simple and brutal, Master. This little monster dared to cause you trouble; it's practically courting death..."

Su Mo turned around, "Stop being so cheeky!"

Xiaohua nodded repeatedly, "Yes, yes, now it's time for the next set of passwords!"

……

Banna, a thousand miles away!

After Zhang Qiling's blood was activated on the millstone, there was a stone door behind Lao Hu and the others.
