The staircase rotates downward, not vertically.

For this staircase that suddenly appeared, Ruoxi and Nangong Jinyu were very puzzled.

"Nangong Jinyu, when did this staircase come out, it didn't come out just now."

"I guess it didn't appear until after the lights went out." Nangong Jinyu's eyes kept looking at the staircase that suddenly appeared. "Xi'er, should we go down for a trip?"

Ruo Xi nodded, and then replaced the fire of the lamp with the strange fire of Yunshui Yulian, which would not be extinguished so easily.

Without further ado, Ruoxi and Nangong Jinyu walked down the spiral staircase, and they didn't know how long they walked before they reached the end.

As soon as he walked down, a few arrows flew over, Nangong Jinyu hurriedly flashed to the side, and pulled Ruoxi to his side, just pressing Ruoxi to the wall, looking at each other, sparks rubbing.

Suddenly, Ruoxi saw a few more arrows coming in this direction, and immediately used Jin Yizhu to surround himself and Nangong Jinyu to block the attack of the arrows.

After an unknown amount of time, the arrow finally did not fly out again.

"Xi'er, it's okay."

Ruo Xi shook his head and said, "There are many mechanisms here, and the Ancient Danding should be here." ”

"But there's nothing here."

"Let's take a look."

Nangong Jinyu and Ruoxi observed everywhere, even the walls.

------------------------------------------------------------------------------------------------------Boundary---------------------------------------------------------------------------------

After looking for a long time, I found a little problem in one wall, the color of this wall is a little different from other walls, and I knocked on it to find that this wall is hollow.

"Nangong Jinyu, come here, there is something wrong with this wall."

Nangong Jinyu knocked and said, "This wall is hollow, and there is still space in it." ”

The red stone on the ground, pick it up, and put it in the hole on the far left side of the wall. ’

Stone?

Reminded by Ling Feng, Ruo Xi found a red stone in a corner and put it into the hole on the far left of the wall as Ling Feng said.

Suddenly, the wall moved, and the entire wall was closed up.

"Nangong Jinyu, let's go."

If you regret to light up the surrounding candlesticks, suddenly the whole stone cave lights up, there is a tripod in front of it, and there are a lot of books next to it.
