The stone door slid to the side, and the dim chamber, which had been lit with an oil lamp, was illuminated by a beam of light.

The people of Chengfeng, who were still talking and laughing, were frightened by this sudden move.

He immediately drew the sword in his hand and formed a defensive formation with the ten black dragon guards, blocking in front of Li Feibai and Ouyang Yin.

"Who?"

There was no response from the entrance, as if the stone door had been opened by itself.

At this time, Ouyang Yin's face was full of surprise.

"Impossible, only me and the prince know about the mechanism, how can anyone know how to open it?"

She shook her head, a hint of horror in her eyes.

"Ma'am, could it be that the mechanism failed and opened it by itself?" Li Feibai asked.

"No, the mechanism I designed has never failed." Ouyang Yin replied confidently.

Hearing the conversation between the two, Cheng Feng became more cautious in his heart.

"Lord Wang, is that you?" He asked cautiously towards the entrance.

Still no response.

After a while, Cheng Feng finally ordered a black dragon guard beside him, "You, go out and have a look."

"Yes!"

Without hesitation, the man ran to the entrance of the cave.

The rest waited with bated breath.

Li Feibai observed intently, looking at Ouyang Yin out of the corner of his eye.

In case of an accident, he immediately subdued Ouyang Yin.

Although he didn't cultivate either, it was more than enough to hold a weak woman hostage.

Fleeting ......

"Uh-huh!"

A muffled grunt came from the exit.

Everyone's hearts skipped a beat, and then they saw the body of the black dragon guard flying back into the cave.

The aftermath did not stop, and he rolled on the ground a few times before stopping.

Cheng Feng took a closer look, and the black dragon guard's chest was sunken, his eyes were bulging, and he had already died.

His eyes widened, and he shouted, "Facing the enemy!"

"Huh"

Lin Tianchong no longer hid, and his body flew into the cave.

"Lin Tianchong, is that you?" Cheng Feng gritted his teeth, his eyes full of anger.

"Tian Chong, you actually betrayed me?" Li Feibai also pretended to be angry.

Ouyang Yin on the side had already lost his face, and he unconsciously hid behind Li Feibai.

"Humph!"

With a sneer, Lin Tianchong had no extra words.

Time is the most precious thing for Zhao Qiancheng and him.

The figure activated, and threw the sword in his hand, Lin Tianchong was like fire and hit Cheng Feng.

"Formation!"

Although he was shocked in his heart, he was a black dragon guard after all, and he was well-trained.

The remaining nine people immediately formed a triangle and surrounded Lin Tianchong in the middle.

Cheng Feng exchanged hands with him, and the black dragon guard was beside him, seeing the stitches, constantly attacking Lin Tianchong.

After all, he was a ground-level master, and Lin Tianchong had just been promoted to the heaven-level, and he was not very familiar with his combat methods, so he didn't have the upper hand under the siege of everyone.

As time passed, he became more and more anxious.

Li Feibai on the side had a full view of the battle situation.

In order to kill these people, you must first deal with the nine Black Dragon Guards.

In a flash of inspiration, he said, "Chengfeng, be careful, the formation can't be chaotic, otherwise you will not be his opponent."

This statement was ostensibly to remind Black Dragon Guard, but it was actually for Lin Tianchong.

I can't stop crying in my heart.

Captain Bai, can't you just shut up? Cheng Feng secretly said in his heart that it was not good.

Originally, Lin Tianchong wanted to kill Cheng Feng first, and then deal with the other nine people.

Capturing the thief and capturing the king first has always been his idea.

But at this moment, after being reminded by Li Feibai, Lin Tianchong's strength in his hand suddenly struck out, knocking Cheng Feng back four or five steps.

Then he lifted the true yuan of his body, wrapped the flames in one hand, and thunder and lightning in the other, and struck out to both sides with all his strength.

"Boom"

"Click"

No matter how elite the Black Dragon Guard is, it is only a group of three, where can they withstand Lin Tianchong's full blow.

A strange sound came out, and in a blink of an eye, the three people on the left had been scorched, and the three black dragon guards on the right had their bones shattered.

They fell to the ground like a puddle of mud.

Cheng Feng was stunned!

He couldn't believe that Lin Tianchong's cultivation had reached such a point.

In just a few steps back, he was able to kill six Black Dragon Guards.

The hand holding the steel knife in his hand trembled a little, Cheng Feng swallowed his saliva, and continued to order:

"Up!"

The three black dragon guards did not hesitate and continued to pounce on the tiger.

Cheng Feng clenched the steel knife in his hand and slashed at Lin Tianchong's feet with all his strength with the momentum of thunder.

Life or death, here is a blow.

But Lin Tianchong didn't seem to care, and in the face of the Black Dragon Guards who pounced on three sides, he quickly shot and killed the three of them.

But at the moment when he made a move, Cheng Feng's steel knife had already reached his feet.

There was no way to avoid it, Lin Tianchong had no choice but to suffer this knife.

Cheng Feng was overjoyed, with his earthly cultivation, no one could stand his full strength.

Even if the other party is a Heaven Rank master.

But the next scene made him and Ouyang Yin dumbfounded.

When the steel knife touched Lin Tianchong's calf......

"Keng"

A sound similar to the collision of metal is made.

Cheng Feng only felt that what he was splitting was not the human body, but the extremely hard fine iron.

This is Lin Tianchong, who devoured the bones of the Star Buddha.

The bones are as hard as iron.

"Bang"

Receiving the force of the counterattack, Cheng Feng's right hand was shocked, and his whole body flew out, the steel knife in his hand had been broken into two, and his right palm was already bloody and blurred.

Lin Tianchong was unscathed, but his left foot was slightly broken.

"No, it can't be." Ignoring the pain on his body, Cheng Feng got up from the ground.

"My steel knife is made of thousand-year-old fine iron, how can this be?"

He kept shaking his head, unable to believe the facts in front of him.

And Ouyang Yin, who was smart and alert, suddenly realized something at this time.

Her eyes widened, and she blurted out, "Star Buddha bones? You are the one who stole the bones of the Buddha."

Li Feibai, who was standing in front of her, sighed secretly: After all, she found out.

I hope that Zhao Qiancheng will be smart enough to prevent Ouyang Yin from speaking in front of Nangong Ding.

Ignoring her words, Lin Tianchong just wanted to settle the battle quickly.

After killing the last three Black Dragon Guards, he activated his body, gathered his strength on his feet, and then jumped high, stepping on Cheng Feng's body as if a demon god had descended into the world.

Originally, his cultivation was lower than that of the other party, and he was already injured at this time, Cheng Feng struggled to avoid the attack, but in the end he was still a step slower.

"Bang"

The whole body was trampled by Lin Tianchong, and Cheng Feng's broken bones filled the hole.

For a while, the secret room was filled with blood mist, full of pungent smell of blood.

"Ahh

In the battle, Ouyang Yin didn't exclaim from beginning to end, but Chengfeng was trampled on by Lin Tianchong, which finally made her scream.

At this point, Lin Tianchong solved all the black dragon guards in the secret room, leaving only Li Feibai and Ouyang Yin.

"Tian Chong, start lightly." Li Feibai smiled helplessly.

"Brother Bai, I have wronged you."

After speaking, Lin Tianchong stretched out his hand and gently patted Li Feibai and Ouyang Yin's necks, and the two fainted.

The movements in his hands did not stop, Lin Tianchong immediately took off the coat of the guard of the Tsing Yi Division on his body, and simply wiped the blood stains on his body.

Then he found an intact body of the Black Dragon Guard, took off his armor, and put it on himself.
