One after another, the Four Elephant Venerables did not move, no different from ordinary stone carvings.

Looking up at the tall figure of the Four Elephant Venerables, Tang Zheng let out a long sigh, recalling the scene during the Battle of Buzhou Mountain.

The Holy Monarch turned the Four Elephant Venerables into this form during the Great War, and he must have hit the back door of the Four Elephant Venerables.

So where exactly is this back door?

Tang Zheng looked left and right, and suddenly, a flash of inspiration flashed, and he exclaimed: "By the way, I remember that when the Holy Monarch flew to the back of the head of the Four Elephant Venerables, the Four Elephant Venerables immediately became like this. Could it be ...... The back door is in the back of the head?"

He stood on tiptoe and rose into the air, landing on the shoulders of the Four Elephant Venerables, looking intently at the back of his head.

I didn't see any clues.

He was not reconciled, and finally found a little clue, how could he let it go.

He reached out and fumbled at the back of his head, his mind firm in his mind - the back door must be in this place.

Click!

When his fingers slid over a place, a crisp sound sounded, and he was overjoyed and hurriedly fixed his eyes.

A small door slowly opened, and he had never noticed that there was a small door in the back of the head of the Four Elephant Venerables, and he couldn't help but be stunned.

In the end, his gaze gradually became solemn, and he said to himself: "Chi You has never told me that the Four Elephant Venerable still has this back door, hmph, it is really an old treacherous and cunning." ”

He looked intently into the small door, and saw nothing in the endless darkness.

He didn't give up, snapping his fingers, and purple real fire rose from his fingertips, trying to illuminate everything in the door.

But the light of the true fire could not penetrate the darkness, as if there was an invisible force that restrained the light of the real fire.

"This ......"

Tang Zheng was shocked, even the light could not penetrate, this door was too deep and unfathomable, and the auspicious and evil were unpredictable.

"Something is wrong, there must be something wrong. ”

Tang Zheng stared at this door scorchingly, it was too small, and people couldn't get into it.

He hesitated, but held out a hand.

There was nothing tangible inside the door, and it was an empty space.

Disappointed, he withdrew his hand.

Do you just give up?

The Four Elephant Venerables are of great use to himself, and he is also the patron saint of the Wu clan, if he is abolished like this, he will not be able to explain to the Wu clan.

"Never give up!"

He gritted his teeth and stared straight at the door, the deep darkness as if it were going to suck him in.

Suddenly-

A spiritual light crossed his mind like lightning, and he subconsciously blurted out: "The Chaos Vajra Recipe is the only magical power cultivated by the Wu Clan, which has been passed down from ancient times, and other supernatural powers have been lost in the long river of history, why is only the Chaos Vajra Recipe inherited?"

The question was like a stepping stone, and his eyes gradually bloomed.

He groaned for a moment, then held out his hand again, this time with the Chaos Vajra Technique, his arm glowing with a metallic sheen.

His Chaos Vajra Technique had already cultivated to the Great Perfection Realm, that is, the Immortal Body, so after running the Chaos Vajra Technique, he boldly reached into the small door again.

Call!

A powerful force enveloped his hand, and a huge attraction enveloped him in an instant.

He didn't have time to react, he exclaimed, and spun rapidly, like a spinning top, and was sucked into the small door.

However, with such a small door, he couldn't get through it at all.

But the great attraction held him firmly, and little by little his body sank into the door.

Click!

The bones rubbed against each other with a screeching sound, and he screamed in a heart-rending scream, as if his body was about to be torn apart.

The Chaos Vajra Technique immediately came into play, resisting the tearing force and the squeezing force of the door.

In the end, his body was actually shrunk several times, and with a pop, he passed through the small door and entered the dark space.

"This ...... If my Chaos Vajra Technique hadn't been cultivated to the Immortal Realm, then I would definitely have been crushed. He palpitated and patted his chest.

"Ouch!"

He couldn't help but scream, and although the immortal body saved his life, he was still injured.

The bones of the whole body were squeezed and deformed, and the bones seemed to fall apart.

He took a deep breath and hurriedly exercised his true qi, which traveled along the meridians, moisturizing the musculoskeletal muscles little by little, and returning the bones to their original positions.

Cultivating to his level, this kind of injury is not enough to kill him, and there is no big problem with treatment.

This is like the original Hundred Changing Star Monarch, although he lost a leg in the great war of the island country, but after a period of recuperation, he grew another leg.

It is not impossible for a cultivator to be reborn with a broken leg.

In particular, the Hundred Changing Star King is good at changing, tall, short, fat and thin people can change, and it is not difficult to recover from a broken leg.

In a few moments, he had finished healing, and then stared at the dark space with wide eyes.

"I'm afraid this is like the world of Sumeru, it is another dimension, and only the Chaos Vajra Technique is the key to unlocking this space. Of course, if the Chaos Vajra Technique had not been cultivated to the Immortal Realm, there would be no way to pass through that door safely. This condition is really harsh, and I don't know who came up with it. ”

Tang Zheng muttered to himself, his heart full of questions.

The Four Elephant Venerable once obeyed Chi You's orders, and he was Chi You's subordinate general, so Chi You must also know this door, and the Holy Monarch couldn't wait to recapture the Four Elephant Venerable, could it be that the Four Elephant Venerable had a big effect?

Although the Four Elephant Venerable is powerful, there are many elite demons under Chi You, why does the Holy Monarch want to recapture the Four Elephant Venerable in every possible way?

The answer may lie in this place. ”

Tang Zheng raised his eyes and looked ahead, although he couldn't see his five fingers, he chose a direction and walked towards the front.

His speed is fast, and he doesn't worry about any traps or anything like that, this space seems to have no end, and he has been moving forward for a long time without finding anything.

"Four Elephant Venerable!" Tang Zheng stopped and yelled, trying to communicate with the Four Elephant Venerable again.

"The hosts. A voice sounded suddenly, this voice was very weak, but it was the voice of the Four Elephant Venerables.

This voice had sounded in Tang Zheng's mind countless times, and he would never hear it wrong.

He was overjoyed, but he didn't expect his call to be answered.

Before, the voice only sounded in his head, but now, it sounded in his ears.

"Venerable Four Elephants, how can I save you?" Tang Zheng hurriedly asked.

"I was trapped in endless darkness and couldn't go back. Venerable Sixiang said weakly.

"Do you know you have a back door?"

"I don't know. ”

Tang Zheng was stunned suddenly, even the Four Elephant Venerables themselves didn't know about the back door, it was too weird.

Could it be that this is the back door under Chi Youbu, and even the Four Elephant Venerables themselves have hidden it?

It is true that this possibility is not ruled out.

Whatever the reason for all this, the top priority is to rescue the Four Elephant Venerables.

"Endless darkness, could it be the darkness around me?" Tang Zheng asked in a deep voice as he looked around.

"Yes, you and I are actually very close, but I can't touch you, I can't go back to my own body, I'm banished into this endless darkness. ”

"Don't worry, I'll save you. ”

"Thank you hosts. ”

Tang Zheng said a lot, but he was worried in his heart, his eyes were black, how to save it?

"I've been wandering here for a long time, getting weaker and weaker, and I'm afraid that as time goes by, I'll definitely disappear. Venerable Sixiang said weakly.

Tang Zheng's heart sank, the Four Elephant Venerable is a holy weapon, and this voice is naturally the instrument spirit of the Four Elephant Venerable.

Once the spirit leaves the holy weapon, it is equivalent to the soul of a person leaving the body and becoming a lonely ghost.

The more time passes, the greater the consumption of the machine spirit.

Eventually, it will be difficult for the spirit to return to the Hallows, and even if it does, I am afraid that the Hallows will be affected and their power will be reduced.

Thinking of this, Tang Zheng's heart couldn't help but tighten.

He pondered.

Although the Four Elephant Venerables didn't know about the back door, this back door was obviously linked to the Wu Clan's Chaos Vajra Technique.

Why did Chi especially set up a back door, and set the key to the Chaos Vajra Technique, and then put it in the hands of the Wu Clan?

"No, I may have thought wrong, this back door may not have been set up by Chi You, perhaps, someone else. ”

"Venerable Four Elephants, who created you?" Tang Zheng hurriedly asked.

"I don't know, but I've lived for a long time, and I don't remember exactly how long. Venerable Sixiang said ignorantly.

"Then do you know Chiyou?"

"Know, I used to fight for him, he was one of my former masters. ”

"What, one of the masters?" Tang Zheng's eyes flashed with a fine light, and he quickly and accurately grasped a key point.

"Wrong, all wrong!" he cried out to himself.

"You weren't created by Chiyou?"

"It's not!"

Hearing this definite answer, Tang Zheng already knew in his heart that his long-standing cognition had been subverted.

The origin of the Four Elephants Venerable was far more complicated than he thought in his heart, it was not created by Chiyou, but an even more ancient existence.

This can explain why the key to the back door of the Four Elephant Venerables is the Chaos Vajra Technique, because this is not the back door set up by Chi You, it already exists.

Perhaps, this can also explain why Chiyou is only protecting the Wu clan when he is in danger, regardless of the life or death of others.

The Four Elephants Venerable is the patron saint of the Wu clan, and has a deep relationship with the Wu clan, and there may be a mysterious connection between the two that Tang Zheng does not know.

Chi You is planning to kidnap the Wu Clan, and he wants to take away the Four Elephant Venerables, but now it seems that his thoughts are too obvious.

He wanted to keep both for himself, and perhaps had other plans besides the plans of the Wild Lands.

"Chiyou, Chiyou, you are really cunning. Tang Zheng sighed.

"Venerable Four Elephants, since you know that Chiyou was once your master, why do you follow me instead of following him?"

"My current master is you, and I only listen to your orders. The Four Elephants Venerable replied without thinking.

This made Tang Zheng happy in his heart.

After experiencing the rebellion of the sword soul in the Battle Soul Sword and being taken away, Tang Zheng became more and more vigilant.

Chiyou is the best at burying mines, leaving a back hand, if you don't pay attention to yourself, then you will be attacked by the other party.
