"It seems that we have to hurry up and find the key," Chu Jingxuan muttered as he looked around the platform. It wasn't until I reached the wall behind the stone table that I realized that I had been drawn to the situation from the moment I entered, especially the dome, the platform, and the treasure chest in front of me, completely ignoring the other things in the cave. I saw a text carved on the wall, with vigorous and powerful penmanship and strong sword intent, writing:

"After traveling to the mainland for several years, I think that I am a talent and a learner, and my martial arts talent is rare in this world. Now that I have traveled so far, I have to look at Mr. Handwriting, and I have been taught by Mr. from time to time, so that I know that there is a sky outside the sky, I understand the righteousness of the world, and I understand the road of life, which is the luck of three lives! I would like to say this to clarify my intentions - Liu Yu Wenzhi in the winter of the thirty-second year. ”

"What? Sword boy Liu Yu actually came here thousands of years ago, looking at the time of the message, at that time he had already become famous in the mainland, and was crowned as the "head of the six sons", it is hard to imagine how terrifying the person he called "Mr". Chu Jingxuan said to himself, "Anyway, two people can travel in the same place across thousands of years, which can be regarded as the fate of cultivation, and he is the hero who saved the country and the people from fire and water thousands of years ago, I should come forward to pay respects", without thinking too much, he bowed to the inscription.

Just as he looked down, he suddenly saw a white point of light flash under the wall at the inscription.

"What is this?" Chu Jingxuan walked towards the shining place with questions, only to see a transparent crystal waiting quietly at the gap between the ground and the wall, as if waiting for its owner to wake it up, this feeling was familiar. Chu Jingxuan stretched out his hand to touch the crystal, and suddenly a warm current spread all over his body, only to see that the originally flat surface of the crystal gradually highlighted irregular grooves, and gradually turned into a key shape, with strange words attached.

"This ...... Let's try it first", Chu Jingxuan walked to the yellow treasure chest with the crystal key, inserted the key into the lock hole, and twisted it to the right, with a "click", the lock of the yellow treasure chest opened. The moment the lid of the treasure chest was opened, a faint dark copper-colored light emanated from the box, and I saw two bronze pills in crystal-shaped bottles, and a note next to it read, "Star Building Pill, as the name suggests, can increase a person's cultivation or condense internal force, however, it can only be used by people whose strength is below three stars or without any internal force foundation, and those who are below three stars can use it for cultivators below three stars, and those who have no internal force foundation can use it to directly improve the first order, and those who have no internal force foundation can use it to increase the probability of their own internal force condensation, People with more than three stars or a foundation of internal force have little effect on it. The prescription is stored on the crystal key, and you can know it after you know the reason", "There is such a good thing, but what is the internal force? , forget that the things here are too profound, go back and dig deeper" Chu Jingxuan thought about it, and put all the medicine bottles, words and keys into his close-fitting special pocket to prevent them from getting wet by the lake water when he returned.

"The first one is so powerful, what kind of good treasures do the white and gold boxes have?" Chu Jingxuan's eyes lit up in an instant.

So I couldn't wait to insert the key into the lock of the white treasure chest, and began to twist it to the right, and with the rotation of the key, nothing happened, but a sound came from the treasure chest.

"Little ghost, do you think this key is omnipotent? Enter the password and screw the key."

"Hey, treasure chests can talk?" Chu Jingxuan asked in shock.

"Naturally, the treasure chest will not, but the person who puts the treasure chest will, since it is a test, naturally you can't clear the level with a key" The voice then came from the treasure chest.

"Who are the seniors?" Chu Jingxuan asked respectfully, but didn't get any answer, "I can't care so much, I have to hurry up." At this time, he also noticed that the dome, which was originally covered with blue light, was now shrinking from the sides to the top, and only more than half of the area was still glowing, indicating that his first treasure chest had wasted too much time.

Chu Jingxuan thought, "The voice on the treasure chest just said, enter the password, where can I enter it?" ”

If you look closely, the surface of the silver lock has a messy texture, and you can turn it with a light touch of your hand.

"It's supposed to be this texture, how does it look familiar." , Chu Jingxuan patted his head, "Isn't this the layout of the nine springs at the bottom of the Sunset Spring?" After that, according to the location layout of several springs in his memory, he moved the lines on the treasure chest, and after all the textures corresponded one by one, he gently twisted the key, and with a "snap", the silver lock opened in response.

Chu Jingxuan stretched out his hand to open the treasure chest, and the silver light flashed, only to see a silver-white scroll placed horizontally inside, looking up at the smaller and smaller blue light area on the dome, he didn't have time to think about it, he quickly put the scroll away, and then turned around and walked towards the golden treasure chest in the middle. As he walked, he prayed, "This treasure chest must not be too difficult, otherwise you will have to give up."

Suddenly, there was a "creak", and when Chu Jingxuan had just walked to him, the golden treasure chest slowly opened by itself, and it did not emit any golden brilliance like the previous two times, only to see an antique thread-bound book inside. Looking at the three words "Travel Chronicles" on it, Chu Jingxuan fell into deep thought for a while, and thought, "According to legend, this "Travel Chronicles" was written by Liu Yu, the son of the sword, after traveling around the mainland, recording his travel process, and all kinds of people on the mainland have been searching for it for thousands of years, but there is no news, and it is only considered to have been damaged in the war a thousand years ago, I can't imagine that it is actually stored here, what kind of person is the village chief's grandfather, and even this kind of treasure has a collection."

"Little ghost, what are you in a daze, hurry up and pack your things, a quarter of an hour will be there soon, and this place will be resealed." A mysterious voice suddenly came, interrupting Chu Jingxuan's contemplation.

Only then did I see that the blue light above the dome was about to completely dissipate, and only a few bits of starlight remained.

"Thank you seniors for reminding me, the kid will say goodbye first, and he will have the opportunity to visit again in the future!" After speaking, he bowed three times to the inscription of Liu Yu, the sword boy, and then turned to leave.

Soon after he left, the cave was completely dark, and in the darkness two voices suddenly quarreled.

"I said, how can you cheat, run out without permission, and hurt the mountain mang?" One said.

"Originally, it was not the scope of the test, it would only slow down the progress, and besides, the old guy said, after this matter is done, he will find a way to give us freedom, I can't wait for a moment" The other retorted.

"You can't give him everything, especially the book "Travelogue", which we spent a lot of money to get," the one who spoke first, still dissatisfied.

"No matter how big the price is, there is no freedom, it is all in vain. You can't go anywhere but around this big lake, we've been here for too long. Besides, I think this kid understands etiquette, I like it, maybe it's a good thing to give him something early, what do you say? The voice behind him asked rhetorically.

"Well, I hope you're right".

Then there was silence in the cave, and there was no sound except for the flow of the lake.
