She shuttled familiarly through the maze-like underground castle. She had been here many times and had a basic grasp of the general direction of the entrance to the tunnel.

However, she just couldn't find the button to open the tunnel on the wall that looked the same as it was covered with luxurious wallpaper.

When I escaped from the tunnel last time, there seemed to be a huge antique wall clock embedded in this wall. That wall clock was the switch of the tunnel. Now that wall has been demolished and rebuilt, and it is as smooth as a mirror. Where is there any conspicuous sign button?

She stretched out her arms and touched here and there on the wall, pressing up and down, left and right, but there was no movement at all?

Suddenly, a flash of inspiration flashed in her mind, and she remembered the Japanese-style building where the little prince Tobang was once imprisoned. How did she discover the darkroom switch inside?

Yes! The smoothness is different!

She had long realized that the original purpose of this tunnel was not for people to escape, but an underground transportation channel for transporting drugs.

This manor is not as peaceful as it seems. Near the manor, she has noticed that there is a huge drug processing factory. However, Yeslo has hidden it very well and has never taken her to visit those factories.

Drug processing factory.

The processed drugs were continuously transported out of the Golden Triangle along the underground train in this tunnel.

Since it is used frequently, the place on the wall that is frequently pressed will definitely be smoother and flatter than other places!

After thinking about it, she took out a small flashlight from her bag and scanned the wall inch by inch from the side. Two-thirds of the wall had been inspected, and there was nothing unusual.

When she reached a wallpaper in the corner, a sunflower holding its head high was printed on the magnificent wallpaper. When the flashlight in her hand passed through the golden center of the sunflower, an almost dazzling light pierced her eyes.

Deep in the eyes!

The black jade pupils shrank rapidly! A touch of excitement flashed across at the same time!

Cheng Liuli put down the bag in her hand and used a flashlight to carefully examine the heart of the flower——

The golden yellow wallpaper with dark lines is exceptionally smooth here, as if it has been rubbed with fingers countless times, so that the golden color at the top of the core has faded slightly. When the flashlight passed by just now, it was this

The light reflected from the place shines into the depths of her eyes!

She put down her bag and carefully touched the stamen with her hand.

Under the thin layer of wallpaper at the stamen, there was obviously a cold touch, like a round lock cylinder. She was basically sure that this was the mechanism of the tunnel entrance!

Pressed hard——

Sure enough, the marble floor under the wall suddenly sank, revealing the familiar wide and deep tunnel!

Cheng Liuli was overjoyed, quickly picked up his bag, and went down the stone steps to the inside of the tunnel.

Inside the tunnel, those exquisite copper lamps with sound and light sensors lit up almost at the same time. The light was not very bright, but it was enough for her to see all the internal structures clearly.

Since the last time it was attacked by artillery fire, this tunnel has obviously been artificially reinforced, and it looks stronger and tighter than the last time we came here.

After entering the tunnel, she looked around, looking for the switch to close the tunnel.
Chapter completed!
