The door to the treasure was not opened easily. It was because Lu Li had deciphered the musical notes.
He had to thank the law of sound he learned in the Sea of Sound.
Even though Lu Li hadn't completely mastered that law of sound yet, it had laid down some foundation for him.
His experience with Divine Glyphs was the reason why it was so easy.
Divine Glyphs and the law of sound were both indispensable. Could someone else have deciphered it?
The door to the treasure was opened but Lu Li didn't get up. Seeing that they were eager to try, he waved his hand and said, "Go in and have a look. I think … the treasures are gone. They must have been taken away."
Lu Li didn't want to go in. Yin Tianfan went in with his team and Yin Ruolan went in as well. Lu Li went to the castle next door.
He didn't know if there were treasures in there but he had a feeling that the door had been opened.
Since it had been opened, it meant that everything inside had been searched.
He walked to the second castle. He walked around and then sat down with his legs crossed to study the musical notes here.
There were musical notes here as well but not the same as before.
After comprehending for an hour, seven or eight people rushed out of the first castle with dejected faces. Yin Tianfan smiled bitterly and said, "The inside has indeed been searched. There's nothing left."
"Let's go to this one. But I don't think there is anything left as well!"
Lu Li picked up the zither and began to play. While he was playing, another picture appeared in everyone's mind — it was a picture of a beautiful girl fighting against a group of beasts in the wilderness. The girl was strong, but the beasts were stronger. Compared to the girl, the beasts were like ants and dragons.
The golden door was opened. Lu Li shook his head and sighed. He walked to the third castle.
Yin Tianfan's expression darkened when he saw this, but he still brought his men in.
This time, Yin Ruolan didn't go in. She followed Lu Li to the third castle.
Lu Li walked around the third castle for three times to memorize all the musical notes. By the time he was done, Yin Tianfan had come out with his team.
Just as Lu Li had expected, there was nothing in the second castle. It was empty. Even the furniture had been moved away. Only a few empty halls were left.
The third castle was opened, but Lu Li still didn't go in. He went to the last castle. He had actually given up.
These four castles were the easiest to break through. Cang Yan was an expert in Divine Inscriptions, he should have broken through all of them and looted all the treasures inside.
As expected!
When Yin Tianfan and the others came out, Lu Li had cracked the fourth castle. They went in and walked around before they came out. Yin Tianfan's eyes were filled with sadness as he stared at the temple.
The four castles were empty. Cang Long and the others could only stay in the temple.
They must have obtained the treasures of the four castles, and it was very likely that their strength had greatly increased. Even if they entered the temple, they might still be killed by them.
Of course, the treasures here were all ancient treasures, and it was very likely that they all had ancient divine imprints.
Cang Long and the others might not be able to use the treasures they obtained.
Just like the Ancient Bugle Sword and the others, they couldn't use them now either.
Everyone turned to the ancient temple. Lu Li began to search on it. As expected, he found some mysterious music notes.
But the music notes here were well hidden. They were among the flowers, birds, fishes, insects, and reliefs. They seemed to be intermittent, not as complete as the ones in the other castles.
Lu Li closed his eyes and used the Trace of Dao to sense. This time, it was much easier for him to observe.
After observing for two hours, he finally found more than a thousand musical notes.
He frowned. The more than a thousand music notes were messy and he felt there were three pieces of music.
In other words, he had to put the more than a thousand music notes together into three pieces and perform them in full to open the door of the temple.
"Four castles, four pieces of music, plus the three here, seven pieces. Hall of Seven Notes!"
Lu Li nodded. He sat down with his legs crossed and began to meditate.
He felt the music would be helpful to his understanding of the Law of Sound. There were many things he couldn't understand before, but now, he was enlightened.
He didn't have time to study the Law of Sound. He had to crack the temple as soon as possible.
Otherwise, if Cang Long and the others got all the treasures, it would be their doomsday.
There was another thing. The exit of the Hall of Seven Notes was probably inside the temple. Therefore, to get out, he had to open the temple.
Everyone gathered in the Divine Temple and quietly pondered. Perhaps they could comprehend some nomological true meaning from these flowers, birds, fish, insects, and human reliefs?
Lu Li spent three days and three nights trying to understand the music. When he opened his eyes, they were filled with sorrow.
He took out his guqin and began to play. At first, the music was intermittent and unpleasant.
But after the time for one incense stick to burn, the music became mellow and smooth. Images appeared in everyone's mind again.
These scenes were very sad. In fact, Yin Ruo Lan burst into tears when she saw the last scene.
In the image, a beautiful girl and a man were walking hand in hand in the garden. They were smiling happily and their eyes were full of affection.
But then, the image changed. The man appeared in the coffin with a blood-red sword on his chest.
The beautiful girl had a frivolous look on the man's face. She climbed into the coffin and snuggled up to the body. In the end, she covered the coffin slowly.
"Buzzing ~"
The temple shone brightly, and a black door appeared. Everyone's spirits were immediately lifted.
But they didn't rush in. They looked at Lu Li.
Lu Li thought about it and said solemnly, "Cang Long and the others should be in there. Be careful."
"Let's go!"
Yin Tianfan took out his bronze armor and put it on. Yin Ruolan took out her Holy Weapon fragment as well. They rushed in at the same time. Lu Li and Yin Chengrui were in the second row, followed by the others.
With a flash of white light, everyone appeared in a large hall. This hall was very imposing and solemn, like a temple.
The hall was empty. There was nothing in the hall except for a coffin in the middle!
That was right!
It was a coffin. What shocked everyone was that the coffin was exactly the same as the one they saw in the images. It might be the coffin of the beautiful girl and the man she loved.
But …
At this moment, the lid of the coffin was open. Everyone scanned it with their spiritual will and found that it was empty. There was nothing inside.
"The lid of the coffin is broken!"
One of them walked over, looked around and said, "The coffin must have been opened. The body inside must have been taken away."
"Cang Long is not a human!"
Yin Ruolan was still immersed in the touching story. She said angrily, "They took the treasures but they didn't let go of the body. This is so hateful.
If I have the chance, I will kill Cang Long with my own hands! "
"Let's go!"
