Jiu'er looked back at him, smiled slightly, and then continued walking forward without saying anything else.

This time, Lu Feifan walked behind her silently.

In fact, both of them were worried and didn't know where they were going.

Unknowingly, I walked into the secret room where Beidi's coffin was previously placed.

Now, basically everything in the secret room has been cleared out.

After most of them were cleaned up, they were carefully sent out, ready to be returned to Jiangzhou and handed over.

As for this secret room, it is now empty. Apart from the occasional incomprehensible patterns on the walls and the floor, there is nothing else.

Some inexplicable patterns...

Suddenly, Jiuer stopped somewhere.

This is where the coffin was before, and there are still marks on the ground that have been pressed down by the coffin for thousands of years.

"What?" Lu Feifan walked over quickly and squatted down next to Zhen Jiuer, "What did you see?"

There were some patterns on the ground, but he couldn't understand this pattern.

Some messy lines and inexplicable directions make the lines completely meaningless.

It's like when a child first learns to draw, he can't even hold the pen firmly and just scribbles on the paper.

It has no shape at all.

"You've got it?"

"These lines seem... not quite right."

Zhen Jiuer stretched out her hand and gently brushed it on the lines.

The lines were drawn by something unknown. They were not deep, but they were recessed into the ground, as if they had been drawn by a sharp weapon.

Lu Feifan also studied it carefully. Suddenly, his expression changed slightly: "These lines have been tampered with!"

"It's two kinds of lines!"

Lu Feifan soon discovered it too.

"Did you bring any paint?"

"Why should I bring paint to a place like this?" But Lu Feifan immediately understood what Zhen Jiuer meant.

He looked around.

The secret room was empty, there was nothing, and it was difficult to find anything.

"Can I take that dirt?" There was only some black dirt in the corner, and I didn't know what it was made of.

"Try it."

Jiu'er nodded, and Lu Feifan immediately handed the flashlight to her, went to the corner, and came back with a pile of black mud.

Jiu'er immediately filled in certain lines bit by bit with the black mud he brought back.

The lines filled with black mud can be quickly distinguished from the other lines.

The original picture gradually began to become clearer.

A lock, a... key!

Lu Feifan shook his hand and the black mud in his hand spilled all over the floor.

"So that's it! So that's it!"

He stood up suddenly and pressed his big palm hard on his chest.

Those dark eyes were staring at the pattern on the ground.

"So...that's it..." Jiu'er also stood up, looked at him, then lowered his head and touched the chain in his hand.

Key, inserted into the lock.

That must be it!

When the concentric key is inserted into the concentric lock, something different will definitely happen.

This must be the answer to the mystery!

"extraordinary……"

"careful!"

Before Lu Feifan's shock had passed, he suddenly rushed towards Jiu'er.

There was a bang, and something fell down above the secret room.

Jiu'er was pushed hard and rolled on the ground several times before he managed to get up.

When I looked back, there was dust all over the place, and Lu Feifan could not be seen at all!
Chapter completed!
