"There's no point in opening this door, right?" Lou Feier poured cold water on her. "It's just a door, right? There's nothing in front or behind. Why bother opening it?"
"Hmm... no way?" Zeng Tao was a little unsure. "Maybe after opening it, it will be... a portal?"
"It's possible." Xu Xin nodded.
"Right!" Zeng Tao immediately became excited after receiving Xu Xin's approval. "Let's go down and look for the key. It must be down there!"
"Do you really think this is a game to explore the castle..." Lou Feier was speechless.
"No need to go down." Xu Xin reached out and took out the ancient bronze knife from his backpack.
He always kept this ancient bronze sword in his backpack.
[Ancient Bronze Sword (Gold): A mysterious ancient sword. After being eroded by time, the blade of this sword has become very fragile and easily damaged. It is best not to use it for attack.
A short sword that can unlock the secrets of the world is the key to opening a certain door.
A short sword that unlocks the secrets of the world, a key that opens a certain door.
Everything is very consistent with the current situation.
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 her fingers trembled slightly.
"This should be the key here."
Xu Xin looked up at the keyhole.
The 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 door is made of crystal, which is extremely hard and heavy, yet very smooth.
Even if ordinary people can find this key, they are basically helpless in opening this door.
However, this is not a problem for Xu Xin now.
His jumping ability has increased now.
"Ah? There's a key?!" Zeng Tao originally looked downstairs, but turned back abruptly upon hearing this. "Where is it?"
"Ah, this... a bronze knife?" Lou Feier was a little confused. "Why does it look so much like a cultural relic?"
Jin Yue and Shi Wanyun also came over to observe the ancient bronze knife 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 about the existence of the key, and no one else present knew about it.
"This is a gold-grade sword." Xu Xin raised the sword, then, in the shocked gazes of the women around him, he stepped on the ground and jumped four or five meters.
There was no handle on the door, nothing for him to grab, so he controlled the strength of his jump so that the highest point of the jump was level with the keyhole. When he paused at the highest point, he directly inserted the ancient bronze knife in his hand into the keyhole!
Very smooth.
The size of the keyhole was exactly the same as the ancient bronze knife. With his precise technique, the ancient bronze knife was inserted into the keyhole with a "clang".
Xu Xin did not continue to hold the ancient bronze knife, but let go and it fell to the ground.
He didn't dare to continue holding the ancient sword. After all, the introduction of the ancient sword clearly stated that the blade was fragile and easily damaged.
It would be bad if he broke it.
"It really went in!" Zeng Tao exclaimed. "Is it really a key? Where did you get this key?"
"You didn't get it here, did you?" Shi Wanyun's gaze shifted from the door to Xu Xin. "Did you bring it in from outside?"
Xu Xin had been in her sight since he came in, but she didn't see where he got the ancient bronze sword.
"Yes, it was brought back by Qin Fu. The blood-veined troll came for this thing." Xu Xin stared at Ju Men and explained.
"Ah?" Lou Feier and Zeng Tao both cried out in surprise, and Jin Yue also opened her eyes wide.
Xu Xin frowned slightly.
After inserting the ancient bronze knife, Ju Men did not react at all.
At the keyhole, only the knife handle lying there appeared rusty under the bright white luster.
Could it be that I need to twist it like a key?
He immediately jumped on the spot, moved to a position level with the keyhole, grabbed the handle of the ancient bronze knife, and twisted it clockwise.
The ancient knife in his hand turned easily, and along with it, the recessed metal keyhole of the entire prototype also turned.
"It's twisting!" Zeng Tao cheered below!
“Pah.”
Xu Xin landed on the ground, and then a strange feeling arose in his heart.
There's something weird about this door!
"Back off, everyone back off!" Xu Xin said as he jumped back immediately.
Hearing this, the women did not dare to be careless and took several steps back with him.
And as they moved, the door's bright white light became brighter and brighter!
From the originally soft light, it gradually became dazzling!
It even made it difficult for some people to open their eyes!
"This light definitely means there's a treasure!" Zeng Tao blocked the light with her hands, squinted her eyes and looked at the door through her fingers, saying excitedly.
The others did the same thing. Although the light was blinding, no one wanted to miss the moment of the door opening.
"boom!"
After a loud roar, the door opened a crack.
Purple-black light leaked out from the gap!
They are very familiar with this color!
"Portal! The color of a portal! I knew it was a portal!" Zeng Tao's voice became even more excited.
"Could this be the portal back to the ground?" Lou Feier was also a little surprised.
Jin Yue didn't say anything, but just took two steps closer to Xu Xin so that she could take action if any danger occurred.
