Box Guardhouse.

Legend has it that the biggest casting achievement of the Gong family, the walls are made of special materials, which can withstand powerful attacks, and even the great god-level sword immortals of the twelvefold realm cannot break through.

It is this box-like, impregnable house that keeps many spicy secrets.

Just like more than fifty years ago, Gong Zhiyu's grandfather designed to be the ruler of Qi Scale, who was in power at the time, that is, the father of His Majesty today, to eradicate dissent.

The dusty secrets eventually became cold marks on the walls, and those with low realms could not leave anything, and those with high realms could barely leave some traces on them.

Follow the traces on the wall, and you will find those legendary heroes.

It's just that they all died here in the same way.

"So, it's nothing to die another swordsmith today." Gong Zhiyu's strange laughter echoed in the room, like the ethereal ghost sound of the night.

Wei Gong didn't believe in any nonsense, so he made a move out of thin air.

The dagger floated upward, and—

Sudden force.

The blue sword suddenly turned into a ray of moonlight and blasted towards the wall on one side.

It was a water-based sword technique with unparalleled manic power, and a pair of eyes in the darkness couldn't help but be sluggish when they saw it.

"Bang!"

There was a popping sound, and the light slowly faded.

On the metallic black wall, a half-meter-long blue light streak first appeared, and then healed quickly at a speed visible to the naked eye......

In the end, only a faint palm-wide trace was left on the wall.

In the darkness, there was the sound of Gong Zhiyu swallowing from nervousness to stability.

Emiya chuckled in his heart.

Wei Gong remembered that the chair that Gong Zhiyu was sitting on before was probably overturned into the ground.

He raised his hand and struck another blow at the open space where the chair had been.

"Bang!"

Still nothing works.

It was then, when the Memory Female Sword flew back into his hand, that Emiya noticed that the corner of the carpet on the floor had been cut open, revealing a metallic sheen like the wall.

What the hell is this made of?!

Looking at it this way, he was afraid that the whole room was made of one material, and on the system in his mind, three big question marks were obviously played.

Materials that don't even know to the system, it's scary.

But Emiya was not going to sit still, he swung his black robe away, only to see him rise again, hold his short sword in front of his chest, and then stab the wall again with great speed.

Huge lightning spread out from his body, and with unparalleled power, it quickly bombarded away.

"Boom!"

With a sword, the electric light exploded, and Emiya didn't see the change.

"Boom!"

Another sword.

Bombarded with precision to the point where the tip of the sword intersected with the wall.

A slight hint appears.

Emiya began to accelerate, and the dagger slammed into the wall at a speed invisible to the naked eye.

The speed was so fast that it brought up an afterimage.

"Boom! Rumble! Rumble! Rumble! Rumble! ”

Electricity jumped back and forth on the wall......

Gong Zhiyu, who was silently observing him in the dark, was dumbfounded, what kind of terrifying person is this, looking at his strength, I am afraid that he has already broken through the tenfold realm......

Moreover, this swordsmanship, although it is popular, but every blow, is bombarded on the basis of the previous blow, if this is not a box house, but an ordinary ......

It took a long time for Gong Zhiyu to react, and now he can finally be sure that it was true that the old man told him that this room could trap the masters of the Twelve Realms.

"Hahahaha...... It's useless. Gong Zhiyu laughed, "Didn't I tell you, the masters of the twelvefold realm can't get out, and our palace family's box guard house is not in vain." ”

Wei Gong was already tired and a little short of breath at this time, and there were fine beads of sweat oozing from his forehead.

Although he was panicking to death in his heart, he didn't want to show any trace of fear for Gong Zhiyu to see.

"Let me tell you, part of my Glow Protector Sword today is actually made of this material, so you can see that it can withstand strong attacks, and it can also absorb and bounce, do you know what I mean?" Gong Zhiyu said calmly.

He has changed from the hunter at the beginning to the hunter now, and there is no longer the initial panic between his words, but he looks at the palace in the dark with a playful and playful eye.

After listening to this, Wei Gong tried his best to restrain the fluctuations in his heart and let himself behave as smoothly as possible.

"Oh, I see, I said who made such an ugly sword."

"......" Gong Zhiyu's mood obviously changed, he was silent for a few seconds, and then his voice turned angry, "Wei Gong, you found it yourself, since you want to die so much, then I will fulfill you." ”

Just as he finished speaking, there was a sudden change in the room.

At first, there was only a faint blue light on the wall, and then it quickly increased, and instantly formed a sky of stars.

Then the light on each point quickly swelled, blurring across the entire wall into a blinding light.

Emiya's heart was cold, and he placed the short sword across his chest.

It was at this moment, in such a hurry, that his short sword suddenly touched the silver six-pointed star talisman he wore on his chest, and it made a clang.

As the sound sounded, a silent murderous aura permeated the entire house, and then the blue light turned into a tangible incomparable sword qi and poured out from above......

The sword light jumped back and forth, destroying everything they could touch, tables, chairs, vases, and for a moment, there was a cracking sound in the room.

After a few moments, the light faded and the whole world fell silent.

There was a soft, Gong Zhiyu's voice in the darkness.

Although he didn't see it very clearly, he didn't have the real feeling of killing Emiya in his memories.

After about ten minutes of waiting, the room was still quiet.

The sound of the machine turning sounded, and a white figure appeared where the chair had disappeared.

Gong Zhiyu wore a white fox fur coat and sat quietly inside.

There was a mess all around, and it was at this moment that out of the corner of his eye, he noticed that in the corner of the wall, there was a half cut of black cloth.

He stood up, walked there quietly, and bent down to pick it up.

Wei Gong's clothes were smashed by the sword qi killing array of the box guard house just now, but what about people?

Just in the middle of the lightning, a short sword suddenly appeared behind him.

Silently and swiftly, it pierced through his vest and broke open his chest.

"Uh......"

Gong Zhiyu held the tip of the sword with both hands and let out a painful snort with difficulty.

"How are you...... Do ......"

His figure froze, then his eyes widened and he fell limply from the air.

The blade of the sword was withdrawn, cold and sharp.
