When the cockroach completely picked out the necklace from the corpse's neck, Xue Hua realized that it was not a magic necklace made of precious metal or anything.

It's just an ordinary ornament made of a simple anti-rust iron necklace.

Underneath the chain, hangs a small metal plaque in the color of brass.

Xue Hua picked up the metal plate and saw a line of small characters engraved on the metal card.

"Whoever sees this sign, you will never know our family's secrets! – Elisabeth Bathory"

"Elizabeth? Isn't that a countess? It seems that it was indeed arranged here... But why... Why did she leave a metal plaque here to remind me that their family has a 'secret'? ”

Xue Hua frowned, puzzled.

Logically speaking, this is simply an act of superfluousness.

If it's just to mock the explorers, it seems too shallow.

Shouldn't the urine sex of the Batory family kill all the outsiders who might know the family secrets?

Just like the countess did under her tower.

Is it because there is no energy, and the back hand cannot be activated?

It is also possible.

But why hang the chain on your brother's doppelganger?

It stands to reason that if it were other explorers who came, then the only way they could see the chain was to kill Alessandro Batory's clone.

It's definitely quite a daunting task.

You know, even the walls in this basement are made of flames, and for the Bathory family, who seems to ignore flames completely, this is completely his home turf.

In this environment, even if the comer is ten levels higher than it, it can still make the other party taste the bitterness.

And when the intruders finally kill this guy after a hard fight, they will be able to get their hands on the seemingly meaningless iron necklace.

If at this time a backhand trap hidden somewhere here is activated.

These explorers may not even be able to see the metal plate, and they will be blown into the sky along with the ruins of the castle.

In this way, the existence of this metal plate is still meaningless, right?

"Forget it, no matter, this kind of puzzle is really painful for people to think about."

"Zagara! Dig three feet into the ground with the swarm for me! I'd like to see what they hide! ”

Xue Hua shook his head, threw the metal plate into the inventory, and then commanded Zagala directly in the mind of the main nest.

He didn't bother to follow these perverted brain circuits to go around in circles, so he directly used his strength to break the trick and dig this place upside down!

Under Xue Hua's orders, the swarm soon began to move.

Because this underground space is really large enough, the number of insect swarms that Xue Hua can bring in is also very large.

They soon spread all over the basement and began to search through the basement inch by inch.

The search was effective, and in less than ten minutes, Zagala told him that the swarm had found a large metal hidden door in the northeast corner of the basement.

However, Zagala also brought bad news.

That is, the swarm can't open that door at all.

"We've tried everything, the strong acid of cockroaches, the minions of jumping worms, the spiny needles of stinging snakes, and even the acid-etched spores of poisonous bacteria and the burning bile of destroyers, but we couldn't leave any marks on that metal door......"

Zagala walked with Xue Hua as he walked there, shaking his huge head in some frustration.

“... So stubborn? What about the poisonous explosion insects? Did Isa's analysis produce any results? Also, why not try to go around the door? ”

Xue Hua sounds a little magical, and there is a door that the Zerg can't gnaw?

Even General Warfield's fortress gate couldn't stop the swarm from attacking, how could this secret metal door from a noble family resist?

"We've tried the Poison Blaster too, Juggernaut, and we've even strengthened the load-bearing structures around it for this! But after the gate withstood the self-explosion of dozens of poisonous explosion insects, it only caved inward, and as soon as the attack of the poisonous explosion insects stopped, the gate was restored again! ”

The adjutant is still analyzing the materials of this door, and Isha seems to think that it is not a metal door! And, Juggernaut, you said that we had tried this method by letting the swarm around the gate, but the room behind the gate, even the walls, seemed to be made of this strange material, and the cockroaches couldn't do anything about them! ”

Zagala details the swarm's efforts to open that damn door, but gets more and more frustrated the more he talks.

Xue Hua listened to its words, and his expression slowly became serious.

He suddenly felt that this so-called Bathory family might have been hiding a very shocking secret all along!

Otherwise, it is impossible to explain why they would build such a secret chamber in a secret shelter that is comparable to fortress-level protection.

......

Zagala took Xue Hua and quickly came to the vicinity of the "metal" gate, and Xue Hua also saw this door where Niu B couldn't even take it with the insect swarm through the vision of the king worm.

It is a silvery-white double open door.

Its surface is as smooth as a mirror, and even from the night vision perspective of the king insect, you can still see the faint cold light reflected in it, and the eyes of the jumping insects on the side.

There is no decoration on the door, not even a grip, and the whole door is about four meters high, and the top is just level with the ceiling of the basement.

This door... How so?

It is very similar to the door of the kind of van car elevator that Xue Hua had seen a lot in his previous life.

However, as an elevator door, it seems a little too big.

Xue Hua touched his chin and waved his hand lightly behind him, and suddenly a sneer sounded from the darkness, and a large number of spiny needles flew out of the group of stinging snakes behind him and smashed directly on the silver-white gate.

However, these sharp needles, which used to be able to tear through steel, only burst into a circle of ripples on the gate, as if a drop of water had fallen into calm water.

This reaction doesn't look like it's blocked......

And the explosive needle didn't explode at all......

It looked more like the attacks were absorbed......

"Isa, do you have any information to offer?"

"Juggernaut, based on observation and verification, this is not a metal door at all, this is a high-density inert energy gate."

There was a rare hint of solemnity in Isa's words.

"High-density... Inert energy gates? Explain, Isa. ”

Xue Hua frowned and finished reading this term, but he couldn't understand what it meant at all.

"You'll need to ask Abbather to find out in detail, but what you can know now is that this kind of door is formed by the compression of high-density inert energy, and any attack on it is useless, it is just to recharge it."

"Recharged?"

"Yes, Juggernaut, if you want to open this kind of door, it is actually very simple, you only need to input a sufficient amount of psionic energy into it, activate the inert energy, and this door will open automatically."

"A sufficient number of... Psionic energy?! Xue Hua raised his eyebrows, suddenly slapped his forehead, and shouted.

"I see! I can see why the words on the bronze medal are so strange! ”

"The words on the bronze medal are not reserved for those explorers who normally defeat its brother's clone! Those explorers will probably only be blown away by the hidden hand here the moment they defeat Alessandro! ”

"That bronze medal is reserved for those who, no matter where they found the underground psionic energy transmission pipeline, and destroyed the psionic energy collection end!"

"The Countess is provoking those people! Because apart from the psionic energy transmission pipeline that can supply enough psionic energy to open this door, no individual or small team has the ability to open this door! ”
