The picture in front of him has changed to the scene inside the Five Elements Palace, Zhou Ruolan is also visiting around the Five Elements Hall at the moment because she is one step ahead, Bai Lidu looks around, and sees that the space in the Five Elements Hall is very huge, and it can also be judged from the structural outline of the hall that the Five Elements Hall should be a circular building.

When he looked ahead, he saw five gates on the opposite wall, and the colors of these five gates were different, from left to right, they were cyan, red, yellow, white, and black.

Bai Lidu took a few steps closer and found that there was a huge five-pointed star-shaped pattern painted in the center of the ground, and a Tai Chi yin and yang diagram was also depicted in the center of the five-pointed star.

"Great poet, come and see, there are still words engraved on these doors." Zhou Ruolan was standing next to the yellow door in the center at the moment, shouting at Bai Lidu.

Bai Lidu walked forward quickly, glanced at the words on the door, and didn't recognize it, the words engraved on the door were obviously not modern Chinese characters, not so much words, but patterns.

"I don't know, it doesn't look like a small seal, and it doesn't look like a golden text." Bai Lidu replied truthfully.

"Stupid, this is the Five Elements Palace, the content to be written on this door must correspond to the five elements, although I don't know this word, but I guess this should be a soil character, because the soil in the five elements is yellow, and the status is higher, and, I think, this word is likely to be an oracle bone inscription." Zhou Ruolan said excitedly.

"Oh, I know a few oracles, let's see the next one" The two of them walked to the next door, which was white and had three mountains drawn together.

"Ha, this is too simple, this is the mountain character, um~ but why not the gold word? Shouldn't the five elements be platinum, green wood, black water, red fire, and loess? ”

"That's right, this is indeed the mountain character of the oracle bone inscription, and I also think it is strange to set the five elements of this mountain, wood, water, fire and earth, and I also asked an old Taoist, what the other party said means is that this gold is refined by mountains and stones the day after tomorrow, it is not a natural thing, and the gold in the five elements should be a mountain."

"Ahh Is there any such claim? You must know that this five-element theory has been followed for more than 2,000 years, and changing one word is a big deal! Zhou Ruolan said.

"Well, indeed, I also wrote an article for this purpose and submitted it to the Yangcheng Evening News, I don't know if it was published, and I also checked some information, for example, in this oracle bone inscription, it seems that there is no golden word, but there is a special description of the Quartet in the oracle bone inscription, if you look at it logically, I think the white corresponding mountain in the West seems to be more reasonable than the gold."

"Well, Baishan does sound more pleasant than Baijin, and I remember that there is also a left green dragon and a right white tiger, if you correspond by mountain, it seems that this white tiger is more reasonable to Baishan." Zhou Ruolan analyzed.

The two of them discussed and inspected several other doors, and soon the patterns on the five doors were all recognized: the word "wood" was written on the blue door, the word "fire" was written on the red door, the word "earth" was written on the yellow door, the word "mountain" was written on the white door, and the word "water" was written on the black door.

"Welcome two knights to the Five Elements Hall for trials."

Just as Bai Lidu and Zhou Ruolan had just recognized the words on the Five Doors, a voice suddenly came from behind him, and Bai Lidu looked back, and an NPC who didn't know where to come out was already standing in the center of the Five Elements Hall at this moment, and the name above his head showed [Trial Mentor Wu Zisheng].

"Teacher, how can I do the trial? Do you want to enter the five gates? Zhou Ruolan asked.

"Please also ask Tutor Wu to guide me and wait." Bai Lidu continued.

"Hehe, don't be in a hurry to try it first, let me tell you about the origin of this Five Elements Hall first~~" Wu Zisheng said slowly.

- System prompt: You have activated the main story "Memories of the Trial Mentor: The Origin of the Five Elements Palace"

This link is not like the previous traditional online games that can be skipped, so Bai Erren had to listen to the story patiently:

"According to my ancestors, the history of this Five Elements Hall is very long, and it is also extremely mysterious, no one knows what year and month this Five Elements Hall was built. One day in the end of the Dharma era, this Five Elements Hall was excavated from the ground by humans at that time, and it was protected by humans, and at the same time, a large number of archaeologists and scientific researchers also began to conduct long-term research on the Five Elements Palace, in order to try to unlock the secret of this Five Elements Temple......"

"With the continuation of scientific research, human beings at that time also seemed to have found the right way to study, but when the research results of the Five Elements Hall were about to be revealed, a disaster suddenly struck for unknown reasons, and mankind encountered a catastrophe in the end times, and the research around this Five Elements Hall was completely stopped......

"Later, the earliest pioneers of the retro camp, through the research results found, transformed this Five Elements Palace, and the successfully transformed Five Elements Hall can pass the trial, so that a retro person can obtain the body of the five elements, so that they can truly control the power of the five elements, and this Five Elements Hall is what you see now."

"Next, the pioneers of the camp referred to the structure of this Five Elements Temple, and built the same Five Elements Hall in several other towns of the camp, as long as the ability to reach a certain level of retro people, they can obtain the body of the five elements through the trial here, in the past thousand years, there are countless talents who have gone out from here, and there are also some great people who have made great achievements."

"If you two want to carry out the Five Elements Trial, you first need to choose one of the Five Gates, and then pass the [Energy Crystal Nucleus] before you can enter the door, and before entering, you can also choose different difficulties for your own trial, the higher the difficulty of the trial, when the trial is successful, the body of the Five Elements will be more powerful, now, if you have prepared the Energy Crystal Nucleus in advance, then you can go to the Gate of the Five Elements and start your Five Elements Trial, remember, before the end of the trial, Be sure to get the Heart of the Five Elements. ”

- Quest Hint: You have obtained the [Trial of the Five Elements] quest sub-quest 3: The Gate of the Five Elements

[Branch Quest 3: Gate of the Five Elements]: Please follow the prompts of the trial mentor, select the gate of the five elements you want to enter, set the difficulty of the trial, enter the gate of the five elements with the energy crystal nucleus, and get the heart of the five elements before the end of the trial task, and hand over the heart of the five elements to the trial mentor after the end, task reward: the body of the five elements.

Well? Energy Crystal Nucleus! It turned out that this energy crystal nucleus was used here, Bai Lidu immediately opened the package, and found that he had actually accumulated 15 energy crystal nuclei, and after checking it, he found that its description had also changed:

[Energy Crystal Nucleus] (blue, crystal): A mid-grade energy crystal, which contains a huge amount of energy, which can be used to enter some mysterious places that need to be driven by energy, level requirements: level 20.

"Great poet, I only have 2 energy crystal nuclei on my body, I don't know if it's enough~~" Zhou Ruolan said.

"Haha, I have a lot of this stuff, I'll give you 5 first." After that, Bai Lidu traded 5 energy crystal nuclei to Zhou Ruolan.

"Well, let's go in now, I'm going to go into the fire gate, what about you?" Zhou Ruolan asked.

As for the choice of the five gates, Bai Lidu had already thought about it in advance, so he replied: "I plan to enter the water gate to have a look, and then we will meet at the NPC when it is over." ”

"Good~~"

The two of them walked to the door they wanted to enter, and when Bai Lidu came to the water gate on the far right, he didn't find where to put the energy crystal nucleus after looking for a long time, and when he touched the door with his right hand, a window popped up:

You are welcome to take the [Trial of Water] of the Five Elements Hall Trial, please select the difficulty you want to try:

[Simple]: Obtain the [Heart of Water] of the Heart of the Five Elements, which can be entered

[Normal]: Obtain the Heart of the Five Elements [Heart of Winter Water], which can be entered

[Difficulty]: Obtain the Heart of the Five Elements [Heart of Frost], which can be entered

[Death]: Obtain the [Heart of Ice] of the Heart of the Five Elements, which can be entered

[Abyss]: Obtain the [Heart of Ice] of the Heart of the Five Elements, to be activated

It seems that the difficulty corresponding to the body of Xuanshui that he wants to obtain should be at the abyss level, but this difficulty still needs to be activated, and the condition for its activation is likely to be to get through the difficulty of death at the upper level, so Bai Lidu directly chose the difficulty of death:

- System prompt: You have selected the death difficulty, please confirm whether to enter?

Enter!

As Bai Lidu chose to enter, he saw a circular hole suddenly open in the wall next to the water gate, and he didn't need Bai Lidu to do anything, so he saw the game character put an energy crystal nucleus into this hole, and then the entire water gate burst out with a black light, and the water gate was opened, and the game character automatically walked in.
