He Yu and Shuang Di also watched carefully around the altar, and He Yu said with a sad face: "Isn't there any hint?" Just four paintings, who knows what secrets are hidden inside? ”

Fen Luo smiled: "There is no hint, but since you have passed the Shenwu trial, it means that you have proven yourself, and the current test is chance." ”

"Oh, I see." He Yu nodded and continued to observe.

"Can I touch it?" Zhang Xun asked, pointing to the altar.

"Yes." Fenluo promised.

Zhang Xun squatted down, pressed his ears tightly to the picture, and gently tapped the gold relief with his fingers, he tried to discern the subtle differences in the sound, but he never found anything, and it took a long time for him to stand up, shaking his head and sighing helplessly.

"Brother Xiaoxun, look here, something seems to be wrong here......" Frost Di, who had been standing next to him, suddenly pointed to the painting depicting the sea of fire.

"What's wrong?"

"In this painting, there seems to be something wrong with the shadows of the characters." Frost said quietly.

When Zhang Xun heard this, he hurriedly squatted in front of the painting and observed it carefully.

Looking closely at the painting, there is a sea of fire under the starry sky, the ruins of the fire are located on the left side of the picture, the flames engulf the villages and cities, extending to the middle of the painting, and there are several people on the right side of the picture, who are hurriedly fleeing to the right, trying to escape the flames.

At first glance, there is nothing wrong with this, but after the reminder of the frost, Zhang Xun found the problem, if there are stars in the sky, then it means that the time is night, if there is a shadow at night, then it must be reflected by the fire, since the fire is on the left side, then the shadow should appear on the right side of the person.

However, in this painting, the shadow of the figure appears on the left side of the body, which is obviously unreasonable. With this doubt, Zhang Xun looked at the other three paintings, but found that the shadows of the characters were not depicted in the other three paintings at all.

Zhang Xun stood up and looked around the temple, at this time, the sunlight spread in from all around, illuminating every corner of the temple, and the seven phoenix tails reflected the seven-colored pillars of light, which set off the beauty of the entire building.

Zhang Xun glanced at the edge of the temple and saw that there were many bronze mirrors used for ceremonies, and he suddenly smiled: "I think, I know how to crack this secret." ”

"Oh? How is it? Fenluo asked.

Zhang Xun bowed confidently to Fenluo, and then said, "Patriarch, if you can put down the curtain again, I need absolute darkness. ”

Fen Luo nodded, motioning for the clansmen to lower the curtains around the temple, and soon, the temple was slowly swallowed by darkness, and finally disappeared into darkness.

"Now, please open the light center of the Divine Phoenix, I need a beam of light."

Zhang Xun spoke, and the light center of the Divine Phoenix slowly opened, and a dazzling bright light shone directly down from above, shining right on the platform in front of the altar.

With this strong light, people's vision was basically restored, Zhang Xun slowly walked to the beam, put his hand into the beam, and the shadow of the hand immediately appeared in the beam, Zhang Xun changed his gesture, and the shadow also changed.

"Light and shadow, light and darkness, hehe, what an opposite!" Zhang Xun walked slowly around the pillar of light, while slowly muttering to himself, "However, although they are opposites, they are interdependent, and people can only see the light in the dark, and conversely, they can only see the darkness in the light." ”

As he spoke, Zhang Xun brought a ceremonial bronze mirror from the side of the temple, and he placed the bronze mirror in the beam of light, and adjusted the angle of the bronze mirror, and when he finished adjusting, the bronze mirror happened to reflect the light on the south façade of the altar, which was the picture depicting the sea of fire.

At this time, the reflection of the bronze mirror cast a shadow on the back of the altar, and the hollow holes on the altar were superimposed and combined in that shadow, and a few words were vaguely presented, Zhang Xun adjusted the angle of the bronze mirror again, and finally, those words were clear.

At this time, everyone was shocked, they could not have imagined that the altar, which had been bathed in light all day, would reveal its hidden secrets in such a way.

"Seven lights are reshaped, reborn from the fire."

"Reborn from the ashes?" Fenluo frowned, a hint of unease flashing across his face.

Zhang Xun read those words, and then said to Fenluo: "Patriarch, you can put away the curtain." ”

Fen Luo nodded in agreement, and then, the curtains around the temple slowly rose, and the light once again filled every corner, and with the dazzling light, the words gradually dimmed, and finally disappeared into a cloud of light.

"These eight words are very clear, I think the mechanism should be hidden in the hedron of the seven phoenix tails." Zhang Xun pointed to the phoenix tail coiled around the pillar and said.

"Well, you go and give it a try." Fenluo promised.

So Zhang Xun came to the pillar inlaid with red spar, and asked the Yue Nu people to bring the ladder, and then Zhang Xun climbed up the ladder, holding the pillar with one hand, and gently pinching the huge red spar with the other.

Zhang Xun slowly exerted force, the spar really rotated, only to see that the red pillar of light also moved away from the top of the altar, and slowly moved to the platform as Zhang Xun adjusted the angle of the spar, when the red pillar of light shone in the center of the platform, only to hear a "click", the position of the spar was locked.

"Can't be wrong, it must be like this!" Zhang Xun didn't bother to get down, stood on the ladder and shouted excitedly to everyone.

Then, Zhang Xun concocted the same method, turning the remaining six spars one by one, and when all the spars were adjusted, the seven-colored pillar of light refocused on the center of the platform.

At this moment, there was a complex sound of mechanical transmission from under the altar, and the stone slab in the center of the platform suddenly sank, revealing a secret passage.

Zhang Xun stared intently at the entrance of the black hole, he jumped more and more, and curiosity drove him to hurry in to find out.

Feng Luo saw Zhang Xun's urgency, but she was not in a hurry at all, and asked, "How did you come up with this method?" ”

Zhang Xun saluted, his eyes still reluctant to move away from the entrance, "I found that the Yue Nu people have a very deep love and thorough understanding of light and shadow, and the seven-colored pillar of light on the altar and the previous rainbow stars all illustrate this, so the shadow in the picture must be a hint." ”

"The Yue Nu people worship the god phoenix, the god phoenix is the red bird, which belongs to the fire, representing the south, and the south side of the altar is also painted with a sea of fire, which coincides, in addition, in the painting of the sea of fire, the direction of the shadow can not be said to be a mistake, if you want to present that effect, you only need to give a stronger light source in front of the figure, therefore, I want to use the bronze mirror to reflect it."

With a relieved look on his face, Fan Luo said, "Hehe, you have succeeded, you can enter now, the secret of the Yue Nu clan is yours." ”

Zhang Xun was very excited, jumped to the entrance with one step, and was about to go inside, but scratched his head and retreated, and said with a smile: "Hehe, it's black inside, I can't see anything, I need a torch." ”

Fenluo smiled slightly, motioned to the clansmen to find some torches, and then, Fenluo ordered people to guard the entrance, and led Zhang Xun, Shuangdi, and He to see the moon, and entered this secret passage that had been sealed for more than 200 years.

The passage was dug downwards and excavated, and although it was rough, it was two people wide. Completely different from what Zhang Xun originally imagined, although this secret passage was pitch black, the air inside was very fresh, and Zhang Xun judged that behind this secret passage must be connected to the outside world, not a confined space. The group walked a few dozen steps along the secret passage to the end of the secret passage, where there was a large gate carved out of heavy wood, and although it was not locked, it was extremely heavy.

Zhang Xun and He Yu took a lot of effort to push the wooden door open, and when the wooden door was opened, everyone's eyes suddenly lit up, only to see that there was a circular secret room here, the top of the secret room was bright and dazzling, and the light swayed like water ripples.

Zhang Xun was very curious, and couldn't help but say to himself: "How can it be this kind of light and shadow?" Could it be that there is water on it? ”

He hurriedly entered the center of the secret room, looked up, and saw that the light emitted was a huge round spar, this spar was located in the center of the secret room to the south, the water on the spar was endless, and the sunlight passed through the changing water lines, dyed with a hint of pale blue, reflecting unpredictable light and shadow in the secret room.

Suddenly, Zhang Xun's mind flashed, he actually had a sense of déjà vu, he recalled the first time he attacked Chen Guo when he met King Chen in the underground palace, this secret room and Chen Guo's underground palace had many similarities in design. Chen Guowanqiu City was built under the auspices of his master, so the underground palace should also be designed by the master. This is designed and built by the ancestors of the Yue Nu tribe, if there are similarities in their works, could it be that the master and the Yue Nu clan also have something to do with each other? The more Zhang Xun thought about it, the more strange he felt, but he couldn't figure it out anyway, so he simply stopped thinking about it.

"Hehe, I see." Fenluo's words interrupted Zhang Xun's thoughts.

Zhang Xun raised his head, looked at the spar above his head and asked, "Could it be that this is the statue of the goddess?" ”

"That's right, this hedron is the bottom of the pool in front of the statue."

Zhang Xun exclaimed: "Exquisite! It's so subtle! ”

"This is just a simple design, the true wisdom of the Yue Nu clan is far more than that!"

As he spoke, he waved his sleeves and motioned for everyone to look around the secret room, only to see that the walls around the secret room were all wooden, and the walls were densely carved with words. Zhang Xun showed an excited look on his face, and he hurriedly raised the torch and ran to the wall, using the light to check the seal carvings on the wall. The content of the seal carving is unusually rich, and the handwriting is still clearly visible.

Zhang Xun was amazed, and he couldn't imagine that more than 200 years later, these handwritings were still so well preserved.

"Patriarch, has no one really been here for two hundred years?"

Fen Luo shook his head and said, "No one has ever been here, and even I don't know about the existence here. ”

Zhang Xun stretched out his hand and touched the seal carvings on the wall, and found that these seal carvings seemed to be smeared with special viscose, Zhang Xun sighed: "It is not easy for ordinary woodcuts to be preserved for decades, and I can't imagine that the woodcuts here can withstand more than 200 years." ”

Feng Luo also stepped forward, took a closer look, and said: "These woodcarvings should have undergone a special antiseptic process, but the specific process method has long been unknown to the clan. Perhaps in these seals, you can find the answer. ”

Zhang Xun couldn't wait to browse the content in front of him, this part talks about the principle of light, and at this time Zhang Xun knew that white light was composed of seven colors. He carefully moved the torch, for fear of burning the woodcut, and then he took a few steps back, stood in the center of the secret room, and looked around again, only then did he find that the seal carving in the secret room was roughly divided into four parts, and a large character was engraved above each part, which were "Li", "Bing", "Omitted", and "Shu", which corresponded to the four major classifications of all contents.

Each of these four categories covers 300 chapters and a total of 1,200 sections. Among them, "reason" covers the Yue Nu people's cognition of natural knowledge such as light, power, fire, and minerals; "Bing" is a summary of military behaviors such as fighting, archery, formation, and strategy; "Omitted" describes the politics, economy and people's livelihood at the level of national governance; "Technique" covers astrological divination, yin and yang alchemy, etc.

Zhang Xun exclaimed: "Sure enough, it is wisdom beyond the times!" ”

"This wisdom is yours, make good use of it." Fan Luo smiled knowingly.

"Patriarch." Zhang Xun saluted again and said respectfully: "At first, you said that the wealth of the Yue Nu clan is the wisdom that transcends the times, I don't think so, but now I am deeply convinced that these wisdoms do surpass the times they live in, and even now, they are far ahead!" But there is one thing that I still don't understand, and I hope that the patriarch will give me advice. ”

"You want to ask why the ancestors had wisdom beyond the times and had the vision to change the world, but they didn't do it themselves, right?"

"Yes, I don't understand this, if I have the ability and vision of the Yue Nu ancestor, I think, I will do it."

Fen Luo shook his head and smiled, "First of all, your question is wrong. ”

"Wrong?"

"The ancestors did not fail to do it, they made difficult attempts to change the world, and paid a huge price for it. Even after a complete defeat, they did not give up hope, but kept all their wisdom in this place, waiting for your arrival. ”

"Why did they fail?"

"Any change is going to be resistant, and the more you want to change, the more resistance there will be. Moreover, the power of hostility is always stronger than you think, it will not only come from the outside, but even from your heart, more than 200 years have passed, you, you, and even me, can not imagine what kind of efforts and struggles the ancestors went through in that era. ”

Zhang Xun frowned and looked around, these wisdoms that transcended the times had passed through two hundred years and appeared in front of his eyes. He couldn't believe what had happened back then, but now he understood that change is never easy, let alone the world, how can it be easily subverted?
