"Little girl, you hold the Night Pearl."

Lan Qianzhen handed the Night Pearl to Mo Huaizhen, and then took out an unlit torch from the Void Realm, and after lighting the cloth stained with oil on it, Lan Qianzhen threw it into the cave.

Others may not know about this move, but if you can do it, you will know that there is usually no oxygen in the old basement or ancient tomb, and there is even miasma and methane.

Lan Qianji's move is to determine whether there is enough oxygen below to provide them with breathing, and it is also to prevent if there is biogas below, there may be a big explosion, which will not do them any good.

Fortunately, after she threw down the torch, the flame of the torch moved, but it did not go out.

"It should be safe down there, let's go down."

As soon as Lan Qianzhen said that she wanted to go down, Mo Huaizhen hurriedly stopped her.

"Wait, there's a trap here."

"Got a trap? Is it stepping on the floor tiles? ”

Lan Qianzhen glanced at the staircase, like many TV dramas have similar plots, stepping on a certain floor tile, a lot of sharp arrows will shoot out on the wall, and then shoot people into hedgehogs.

"Stepping on the tiles?"

Mo Huaiqing was stunned, what is this?

He couldn't keep up with Lan Qianji's thinking a little anymore.

"It's that if you step on a certain staircase or a brick underneath, an arrow will shoot from the wall, and then you will be shot into a hedgehog."

Lan Qianzhen looked at Mo Huaizhen with a confused look, thinking that he wouldn't know what was going on with stepping on the floor tiles, right?

"That's what you said about stepping on the floor tiles, I thought it was something about."

Mo Huaiqing laughed lightly, grabbed the small stone from the ground that was coming towards the two people, and threw it towards the stairs.

Before he could react to the small stone, he rolled down the stairs with a thud.

"Ahhhh

The little stone let out a scream and lay on the ground in a daze.

"Hoop, there is no danger, let's go down."

Mo Huaizhen ignored the screams of the little stone, took Lan Qianzhen's hand, and stepped onto the stairs.

"Little white face, you, you."

Xiao Shi saw that Mo Huaizhen didn't have any words to comfort him, so he pulled Lan Qianzhen down the stairs and was angry.

"Little stone, you have to get used to it, the little white face is for the good of the little girl. We're just supporting roles, do you understand supporting roles? ”

The little white snake opened coolly.

"I don't want to understand."

As soon as Xiao Shi muttered a few words, he heard a slight clicking sound coming, and then several sharp arrows struck at Lan Qianzhen and Mo Huaiyu.

Before he had time to say be careful, Lan Qianzhen made a move, and Xinghe galloped and pulled Mo Huaiyu to rush below.

It's amazingly fast.

Little Stone and Little White Snake were shocked by Lan Qianji's speed.

"Strange, didn't the little stone already try it just now? How can a sharp arrow be shot? ”

Lan Qianzhen looked back at the sharp arrows on the stairs, and couldn't figure out how the little stones were okay when they came down, and they came down and became people who had something to do.

"Gravity."

Mo Huaiyu grabbed the small stone on the ground, threw it again and again, and directly threw the small stone into a daze.

"I see what you mean, the gravity of the small stone is different from ours, the power of the small stone itself cannot trigger the mechanism, but our weight can make the mechanism activate."

Lan Qianzhen is not stupid, and he will not know the principle of this.

It's just that she thinks her father and mother are too cautious, and she almost didn't shoot them into hedgehogs on this trip.
