Xu Changqing observed the base of the tombstone carved in gray stone and tried the raised part near the edge. "A floating trap," he nodded, "as long as someone dares to pry the tombstone, the whole platform will collapse immediately, so it's easy to design." ”

For the next period of time, Xu Changqing walked around the edge of the platform, and kept muttering: "The twenty-first gap, the twenty-first gap in the tomb...... Where the hell is this thing? Aha, got it! He measured the circumference of the altar with his feet, and divided it evenly into seven parts. He walked step by step, muttering numbers in his mouth, pausing every few steps to check the stone bricks on the ground. After walking a few times, he began to flip through the thick book again, comparing it carefully.

"Ah...... So boring. ”

The succubus Shinda stretched and continued to wander around the altar. The edge of the altar was carved with delicate patterns, and if it weren't for Xu Changqing's careful brushing away the rubble and floating dust, she really wouldn't have paid attention. The pattern is mainly some simple lines. They are staggered in a wonderful rhythm, repeating themselves. She walked over and crouched down to gently caress the lines.

"Seven is a mysterious number that encompasses the cycle of the world from its inception to its destruction. According to the seven paragraphs, these patterns have meaning. Hmm, it must be some kind of ciphertext. But why is every word plausible and completely unsentenced? Xu Changqing frowned, his fingers tapping back and forth on the ground. He stared at the succubus touching the edge of the altar in a daze, his eyes following her back. Suddenly, he jumped up as if he had been burned and shouted, "You, don't move!" ”

"Huh?"

The succubus Nobuta looked back at Xu Changqing with questions. The latter rushed at her excitedly, and kept saying, "Shadow, I know, it's a shadow!" ”

"What shadow?"

Xu Changqing didn't care too much to explain, and directly led Xintian to a stone pillar. The demonic fire of this pillar was the strongest, and the white light was beating non-stop. The shadow of the column head points straight to the pillar altar in the center of the altar. Where the shadow of the demonic fire squirmed, the stone bricks on the floor were etched with an ancient symbol.

Symbols, ciphertexts, altars, patterns, they are mixed together in a disorderly manner, and each word is a fragment of truth. Xu Changqing made each symbol into a card, spread it on the ground, and struggled to piece it back and forth. The succubus Nobuta watched him tinkering with great interest, and suddenly suggested, "I may not know much about symbolic ciphertext...... But if you put the page you have on top of it in the middle, does the order change? ”

Xu Changqing glanced at her, shook his head and said, "Those are the ciphertext on the bricks, the bricks are all laid, how can it be - that's right, you are right, you should try." ”

He walked around the altar, grabbed the concave pattern on the tail of a stone brick, and with a force back and forth, the seemingly tightly knit brick actually slived. The stone bricks moved like quicksand, and as soon as one was pushed away, several others rushed over to fill the gap. The pattern on the surface of the altar also changes. Xu Changqing pondered while pushing, first moved the piece close to the edge, and then moved the upper left side.

In less than half an hour, Xu Changqing clapped his palms and said with satisfaction: "It's done." ”

Illuminated by the white flames, the altar took on its original purest beauty. The original chaotic patterns are staggered and fused, spliced into a huge lotus flower. A dragonfly perched on the tip of a petal, its tail cocked straight at the central altar.
