Xi Yu nodded, he took a deep breath, slowly stretched out his hand, and pressed it on the key groove...

The next moment, everything in the underground palace seemed to be controlled by a mysterious force, the ancient stone wall began to tremble, the bronze chains made sharp sounds, and an indescribable tension filled the air.

"Click--"

It seemed as if the sigh of the ancient giant beast was touched, and it was like a mechanism that had been covered with thousands of years.

The twin pendant in Cai Wen's hands is perfectly embedded in the groove on the bronze door.

At that moment, the earth shook!

Cai Wenshuang felt that his feet were empty and he almost fell down. Fortunately, Xi Yu was quick-witted and held her in his arms.

The two of them looked down and saw that the solid ground of the underground palace was cracking like a spider web, revealing a bottomless black hole.

"This is..." Cai Wenshuang exclaimed, his voice trembling.

In the black hole, crystal clear crystal coffins slowly rose.

In each coffin, there was a lifelike ancient man who was dressed in costumes from different dynasties and had a peaceful face, as if he had just fallen into a deep sleep.

"These... are all the masters of Tianji Pavilion from all generations?!" Xi Yu's voice also brought a hint of shock.

He read a lot of books and naturally knew the legend of Tianji Pavilion, but he never thought that he would see these legendary characters with his own eyes in this way.

Su Heng stood aside and looked at all this with a complicated expression.

Her eyes swept over the crystal coffins one by one, and finally fell on Cai’s father.

"You... have known it a long time ago, right?" Su Heng's voice was very light, but there was a hint of imperceptible tremor.

Cai’s father did not answer, he just stared at Su Heng with a crazy light flashing in his eyes.

Just then, Xi Yu suddenly took action!

He grabbed Su Heng's wrist like lightning, with such a great force that he seemed to crush her bones.

"The bloody letter in your sleeve was the farewell letter written to me by Cai's father twenty years ago?!" Xi Yu asked sternly, with rage burning in his eyes.

Su Heng's face changed. She tried to break free, but found that her wrist was as if it was tightly clamped by iron clamps and could not move at all.

"You...how did you know?" Su Heng's voice finally brought a hint of panic.

Xi Yu sneered, without an answer.

He had long suspected Su Heng's identity, but there was no conclusive evidence.

It was not until just now that he saw Su Heng subconsciously touching his cuffs that he finally confirmed his guess.

"Tell me! Who are you?!" Xi Yu asked again, his voice as cold as a knife.

"I..." Su Heng opened her mouth, but said nothing.

At this moment, a sudden change occurred!

Cai's father suddenly let out a wild roar, suddenly picked up the bronze giant tripod beside him, and smashed it hard at Su Heng!

"Old Cai, you're crazy!" Cai Wenshuang exclaimed in surprise, trying to stop it, but it was too late.

"boom--"

The giant bronze tripod hit Su Heng heavily...

However, the expected scene of flesh and blood flying did not appear.

The bronze giant tripod actually penetrated Su Heng's body directly, as if she was just a phantom.

"This..." Cai Wenshuang and Xi Yu were both shocked.

What's even more strange is that the "royal key" originally embedded in the groove of the bronze door actually flew out automatically and shot straight into Su Heng's back!

"Ah——" Su Heng let out a shrill scream and his body trembled violently.

"You are the real core of Tianji Lock!" Cai's father roared, his eyes red, as if crazy.

Xi Yu's eyes fell on the leader of the secret guard.

He suddenly discovered that the same bronze pattern as Su Heng appeared on the neck of the secret guard!

The patterns, like living things, slowly squirmed, emitting a strange light.

"Is this... Could it be..." Xi Yu flashed a thought.

Su Heng slowly raised his head, blood spilled from the corner of his mouth: "Do you think...you are the only ones...will be able to calculate?"

The bronze tripod, which was as heavy as the falling moon, rushed towards Su Heng.

Cai Wenshuang shouted "Father, don't!" and was drowned by the howling sound of the airflow.

The sound of bone shattering and splashing blood that should have been heard did not appear.

On the contrary, the cauldron "passed through" Su Heng directly, as if she was a phantom, a wisp of smoke.

Cai Wenshuang and Xi Yu stared at him in amazement.

A silence came, and the air was filled with a strong smell of ozone.

Then, the "Key" embedded in the complex carving of the bronze door flashed with strange blue light.

It broke free, and slashed the air with the sharp whistle of metal, and then pierced into Su Heng's back.

Su Heng screamed, and the voice seemed to tear apart one's reason.

Her body twitched like a puppet tangled with strings.

"You...you are the real core of Tianji Lock!" Cai's father roared, his eyes covered with bloodshots, and his face twisted with anger.

But Xi Yu's eyes fell on the captain of the guards.

The bronze patterns that were exactly the same as those that were spreading to Su Heng were climbing up the captain's neck, flashing with a sickly light.

A terrible thought flashed through Xi Yu's mind.

*Is it...?

*

Su Heng slowly raised her head, and blood flowed down from the corner of her mouth.

"Do you really think...only *you*...can you calculate?"

Xi Yu staggered back, and his right arm felt a sharp pain like a knife cut.

Cold and hard jade scales emerged from under his skin and spread like malignant tumors.

He took a breath of cold air, his mouth full of copper smell.

"The forbidden art of the opera artist you stole many years ago..." a voice said hoarsely, making him creepy.

Xi Wujiang's ghost form emerged from the ground, and fragments of his broken armor circled around him, and piece by piece was recombined.

He is like a horror puzzle pieced together by bones and steel, his eyes burning with cold, otherworldly flames.

Then, a figure rushed out of Xi Wujiang's chest, breaking through the ghost armor like a newborn breaking out of his mother's uterus.

It was a woman in purple. She showed her true body and exuded an ancient and evil power.

Xi Yu's breathing was frozen in his throat.

Only then did he see that there was a mark on his brother's neck, exactly the same as the twin stars shining on his own forehead.

"You have always been *bait*!" Xi Wujiang's voice was filled with venom, and the thousand-year-old resentment was condensed into a sentence.

"*I* is the container chosen by the Tianji Sect!*I* is the legal heir!"

Cai Wenshuang raised his hand to cover his mouth and suppressed his exclamation.

She looked at the simple childhood jewelry on her neck, the goat pendant, trembling violently, then broke off the leather rope and flew towards Xi Wujiang.

The two stars on Xi Yu's forehead jumped with the irregular flight of the pendant.

A sharp and painful memory flashed through Cai Wenshuang's mind - the fire that devoured the Xi family's military camp, the screams echoing at night.

"Did you set fire to the Xijia army... to cover up the fact that *you*... are the real heir?" she said softly, her voice almost inaudible to her violent heartbeat.

Xi Yu's dark eyes full of pain and confusion met Cai Wenshuang's eyes.

He opened his mouth to speak, but he couldn't say a word.

He shook, his body suddenly became heavy, and the burden of betrayal made him breathless.

The bronze scales on his arm were beating, emitting a sickly heat... [Event]

Xi Yu suddenly laughed to the sky, his laughter filled with ridicule and determination.

The laughter was like an evil ghost crawling out of the Nine Nether Hell, tearing the strange silence.

He was shocked suddenly, and the bronze scales that had already spread to his chest were forced to retreat back to his right arm!

"Hahahaha... Xi Wujiang, do you really think I, Xi Yu, is a puppet at the mercy of others? Do you think this so-called blood contract forbidden technique can really control me?"

His right arm swung violently, and the bronze light that had originally entangled it rushed towards Xi Wujiang like a tamed beast!

The light, with the aura of destruction, seemed to devour all the creatures in the world.
