Chapter 512 Behind the door are secrets about the world

What is going on with that altar?

Xu Xin felt like his whole head was going to explode.

The thought just now lingered in his mind.

Although his idea was unbelievable, the more he thought about it, the more he felt it was possible.

Although, there are some obvious loopholes in his reasoning.

For example, the altar that Qin Fu said had been destroyed that was directly above his head was related to the blood-striped mutated creature from the very beginning.

The first time he came into contact with the altar, he offered sacrifices to the altar, causing the stone statue to break into pieces and a blood-striped creature to pop out.

But here, this Crystal Palace obviously does not belong to the same force as the Blood Pattern Clan.

Somewhat like...that giant's force?

Moreover, the altar is not just on his side.

There is also one over there at Ji Chaoyang.

It's impossible for Ji Chaoyang to do the same...

Um……?

"What's wrong with you?" Shi Wanyun had been paying attention to Xu Xin. Seeing that his expression was a little strange, he immediately asked, "Did you find something?"

"...I just speculated on the current situation." Xu Xin's eyes flickered and he said.

"So, how did this guy get here?" Zeng Tao pointed to Qin Fu, who was still unconscious and sitting on the ground leaning against the giant door, "We came up with you, could it be said that he also has this sense of déjà vu?

?"

...should not be possible.

However, if you want to know this, just ask him directly.

Xu Xin took out a pill and stuffed it directly into Qin Fu's mouth.

However, Qin Fu's condition did not improve, and he was still in a coma and did not wake up.

"...Ah, isn't this guy in a weak state?" Lou Fei'er suddenly said, "Isn't his weak state just like this, listless?"

really.

Xu Xin also thought of this possibility when Qin Fu didn't wake up.

Compared with the obvious physical weakness of several other people in their weak state, Qin Fu's weak state is indeed invisible from the surface.

"...Did he get here through an explosive state and rely on highly concentrated mental power to avoid those traps?" Jin Yue speculated.

"Ah? No way..." Zeng Tao disagreed, "If it were me, I wouldn't enter an explosive state here. What should I do if I become weak after the state ends? Isn't that looking for death?"

"What if you are forced into an explosive state?" Lou Fei'er said, "Xiao Taozi, you haven't passively entered an explosive state yet, have you?"

When dying, people with mutated bloodline will automatically recover from all injuries and enter an explosive state.

Of course, this depends on the severity of the injury. After all, fatal injuries also come in different sizes.

If the person's throat is cut or the head is penetrated, and the scope of the injury is very small, then after the injury recovers, the remaining strength is enough to support the body's movements, and it will enter an explosive state.

But if, like Ma Hongwei before, his whole body was crushed by a giant anaconda, and he exhausted all his strength to recover from his injuries, he would fall directly into a deep sleep.

"It is possible that he entered the burst mode on the layer below, and then relied on the powerful mental power of the burst mode to avoid the trap and enter here." Jin Yue speculated.

"Ah? Then if I saw such a terrible trap, I would not continue walking up. I would go back the same way." Zeng Tao continued to complain.

"Then die underground?" Lou Fei'er said angrily, "It's possible to find a way back to the ground if you go up there."

Shi Wanyun stood behind a few people. Some of them didn't understand what they were saying, so they didn't interrupt.

However, she still understands the current situation.

She had just undressed and applied insect repellent in a room with Jin Yue and Zeng Tao, and she had seen the blood streaks on their bodies.

Moreover, when she met these people, she could already feel the mutated blood in them.

Therefore, she was not confused and just stood back and listened silently.

Xu Xin touched her chin and looked at Qin Fu who was sitting in front of the door.

He had another guess.

He had spoken to Qin Fu on the way down before.

At that time, his intermittent and vague words seemed to mention the word "palace".

In other words, he was probably already in this palace at that time.

According to what Shi Wanyun, Zeng Tao, and Jin Yue said, the palace at that time had not yet revealed its original appearance. From the outside, it looked like just a palace made of stone.

And if the palace does not show its true appearance, maybe... there won't be such a powerful trap?

After that, he and Lou Feier quickly opened the door and activated the entire area.

Perhaps, at that time, Qin Fu, who was about to ascend to the top, was attacked by the activated palace.

if it is like this……

Maybe he is also responsible for Qin Fu becoming like this...

Forget it, no matter what, he can't wake up now, so it's of no use for the time being.

Xu Xin turned the bracelet and put the unconscious Qin Fu directly into the bracelet, then stood up and looked up at the door.

At this time, Shi Wanyun spoke: "I just observed this door. There is a big keyhole in the center of the door, which requires a key to open."

"Key?" Zeng Tao also walked around to the front and looked up, "There really is a keyhole! Hey, do you think the key is somewhere on the two floors below?"

She pointed to the passage leading downstairs: "Should we go down and look for the key?"

"It's useless to open this door, right?" Lou Fei'er poured cold water on her, "It's just a door? There's nothing behind or behind it. Why bother to open it?"

"Um... no way?" Zeng Tao was also a little unsure, "Maybe after opening it, it will be... a portal?"

"It's possible." Xu Xin nodded.

"Right!" After receiving Xu Xin's approval, Zeng Tao immediately became excited, "Let's go down and look for the key. The key must be down there!"

"You really treat it like a game to explore the castle..." Lou Fei'er was speechless.

"No need to go down." Xu Xin reached out and took out the ancient bronze sword from his backpack.

He always keeps this ancient bronze sword in his backpack.

[Ancient Bronze Knife (Gold): A mysterious ancient knife. After the erosion of time, the blade of this knife has become very fragile and easily damaged. It is best not to use it for attacks.

A short knife that can unlock the secrets of the world is the key to a certain door.】

The dagger that unlocks the secrets of the world, the key that opens a certain door.

Everything is very consistent with the situation at hand.

That's right, what we need now is this ancient sword!

And behind this door...

The secret of the world?

"This is..." Behind him, Shi Wanyun's eyes flashed and his fingers trembled slightly.

"This should be the key here."

Xu Xin looked up at the keyhole above.

This door is five meters high, and the keyhole is located about five meters away, in the center of the entire door.

Except for the keyhole, the entire giant door is made of crystal. It is extremely hard and heavy, but also very silky.

Even if ordinary people can find this key, they are basically helpless to open this door.

However, this is not a problem for Xu Xin now.

Now, his jumping ability has increased.

"Ah? Is there a key?!" Zeng Tao originally looked downstairs, then suddenly turned back when he heard this, "Where is that?"

"Ah, this... a bronze sword?" Lou Fei'er was a little confused, "Why does it look so like a cultural relic?"

Jin Yue and Shi Wanyun also came over to observe the ancient bronze sword in Xu Xin's hand.

When Qin Fu gave the key to Xu Xin, only Li Wenxi was present, so only Xu Xin and Li Wenxi knew the existence of the key, and few people present knew about it.

"This is a gold-level sword." Xu Xin raised the sword, and then, in the shocked eyes of the women around her, she stepped down and jumped four or five meters on the spot.

There was no handle on the door, nothing for him to grab, so he controlled the intensity of his jump so that the highest point of his jump was flush with the keyhole. When he stopped at the highest point, he directly aimed the ancient bronze sword in his hand.

The keyhole went in!

Very smooth.

The size of the keyhole was exactly the same as the ancient bronze sword. With his precise technique, the ancient bronze sword was inserted into the keyhole with a "clang" sound.
