After Feng Chenglin returned the broken bronze mirror somehow, he assisted the two of them to find the fourth bronze mirror.

"Now that's all right, we can search this hall quickly..."

The light from the fourth bronze mirror was folded out and shot into the darkness.

Ling Luoyu's eyes wandered along the light: "Fat man...look at the lens of the light!"

Feng Chenglin was taken aback: "What are you going to see there?"

"Generally speaking, this kind of light mirror is continuous and continuous, and will not end until all the darkness is illuminated..."

"Long?" Feng Chenglin looked at the light, frowning in a speech, "You mean, there is something else behind that?"

"You didn't mean that the house was tied from the inside, but no one left yet?"

"...Oh!" Feng Chenglin suddenly walked over: "I see, you mean, those people escaped from there!"

At present, that place is just a wall.

But according to Ling Luoyu's thinking, here should be a channel.

Ling Luoyu greeted the old treasurer, and the two searched in the palace's inner palace again, and they made sure that there was nothing before they walked towards Fengchenglin.

"Fatty, how is it?"

"I didn't find the mechanism, but listening to the sound, it should be empty over there..."

Feng Chenglin banged on the wall.

"Listen, the voice is very hollow..."

The old shopkeeper strode forward and suddenly kicked his foot on the wall without warning

"boom!"

The wall collapsed and the dust was everywhere.

"Isn't this open?"

He walked in with a cold hum, completely ignoring Feng Chenglin's expression on that day.

"This...what's wrong with this old man? Why is he suddenly so irritable?"

He has always felt that this old man is a person who knows how to see the wind and the rudder!

Otherwise, he wouldn't have been a human being with his tail tucked in, and would close himself in the dust.

But now--

"San Shao, there seems to be something wrong!?"

He quietly looked at Ling Luoyu and found that her eyes were a little wrong.

"Three young masters?"

Ling Luoyu looked down: "When I was at the gate of the palace just now, didn't I pull you to shut your mouth and hold your breath?"

"Yes"

"The dust should be a kind of poisonous fog..."

Feng Chenglin: "..."

Can dust be poisonous fog?

"Then we now?"

He looked at his feet subconsciously.

By their side, there is dust everywhere.

In this way, are they also poisoned?

"The dust around us is different from hiss!" Ling Luoyu's eyes were a little different: "The dust that opened the door just now, in the smell of earth, there is a special fragrance. The more so, the more strange!"

Therefore, she pulled down Fengchenglin in the first place.

However, in the bones, she did not act on the old shopkeeper.

This is an instinctive reaction and action.

In her heart, only Feng Chenglin is the most important.

"Scent?" Feng Chenglin took a breath and lowered his voice: "Why didn't I smell it?"

"With your cultivation base, it is a good thing not to smell it!" Ling Luoyu lowered his voice and looked inside the hole: "Now that it's up, let's be careful and avoid him!!"

"I feel so too!" Feng Chenglin glanced at the ruined rubble under his feet, and drew his mouth: "This old man's temper has become a bit irritable, I guess, if it is really like what you said, I'm afraid to pass it again. After a while, it will be more grumpy..."
