If you don't listen carefully, I'm afraid you won't really notice.

It seems that this wall really has the effect of echoing, so if you destroy the wall all the way, the source of Xiao Yin can be revealed!

The corners of his lips drew a quiet arc, and Yun Chengcheng didn't dare to underestimate the enemy this time, but he came to the wall, and the knife in his hand slammed on the wall, and instead of the dull sound of stone, it was the crisp sound of metal.

Yun Chengcheng knocked again, but found that this wall was also different from ordinary metal, with a hint of gloom in the tone, and a trace of amazement crossed his eyes for a moment.

The person who built this secret passage really dared to make a bloody investment.

Judging from the sound that came, the wall was made of a single piece of pure gold, and the sound quality was lower and more solid than that of other metals.

The whole piece of gold is different from the wall made of gold bricks, the latter transmits sound, which will have a more or less incoherent effect, while the former is the best medium for sound transmission!

And this thin layer that covers the pure gold wall should be a special stone wall that prevents the pure gold wall from being damaged.

It's just that the people in the secret path still didn't expect that the toxicity of the red-tailed poisonous scorpion combined with water would become the most toxic and corrosive liquid in the world.

With the right approach, it's easy to destroy this echoing wall!

Yun Chengcheng's eyes flashed, and the knife in his hand used his strength, only to hear a click, and the wall that had just been corroded by the venom was sparsely cracked.

The wall, which originally seemed to have no problems, turned into pieces in an instant, crackling and smashing to the ground.

Well, that's it!

The Jumang knife changed direction, Yun Qicheng's fingertips were lightly picked, and the Jumang knife danced again and again, and the venom that originally splashed on the ground and corroded the stone wall was caused by the knife qi, and it was thrown on the wall one after another.

In the piercing sound of corrosion, a bunch of pitted holes appeared in the originally smooth and flawless wall, and then with soul power pressure, the wall was directly and completely shattered!

Now, she wants to see, without the echo wall, how does Xiao Yin's origin want to hide?

Boom - Boom -

The smooth stone wall on the right was shattered by her successive blows, and Xiao Yin's echo became weaker and weaker, gradually revealing clues.

But the blade tower behind him was getting closer and closer, and Cloud Fallen City could almost feel the danger and trembling of the end of his hair being cut off.

Can't wait any longer!

The sentence knife in his hand was heavy, and Yun Chengcheng clenched his hands and aimed at the stone wall in front of him.

"The sixth form of the Jumang Sword Technique - Jumang roars!"

An earth-shattering roar came from the sentence mangdao.

The secret passage began to tremble wildly, and the small pebbles that fell to the ground were turned upside down.

The powerful shock wave swung out from the Jumang knife and landed on the stone wall, only to hear a loud bang, the already torn stone wall was blasted in an instant, revealing the filling inside!

Cloud Allure's eyes lit up.

"Sure enough, it's gold!"

Hidden by the stone walls, there are indeed walls of pure gold, which stretch forward in a long way.

And in this piece of golden light, a closed golden gate is particularly conspicuous.

Finally found a place to get out!

Yun Chengcheng no longer hesitated, took three steps and made two steps, and went straight to the golden gate, and with a backhand split, the heavy golden gate collapsed under the blow of the Jumang knife.

Behind him, he could already feel the coolness of the blade cutting off his hair, and Yun Qicheng couldn't care about what kind of knife mountain and sea of fire was in the door, so he clenched the knife and plunged into it.
