In this dark corridor, the light of Yuchen and the others could only be found about twenty meters, which was obviously not enough for everyone to get a glimpse of the whole of this passage.

"I'll take a look at what's going on here!" Yu Chen's curiosity rose, and as soon as his mind moved, a dazzling green light emanated from his body, and the green light spread out towards the surroundings, like an all-round searchlight, but the time of this searchlight was a little short, and it was only a flash, but even so, Zikong Bing and the others still caught a glimpse of the appearance of this huge road. One by one, they couldn't help but open their mouths wide in shock.

Yuchen had already turned into a blood god mink, and under the gaze of his ruby-like eyes, Yuchen finally saw the surroundings completely.

This...... How could it be like this? Yu Chen's heart suddenly surged with an indescribable 'agitation', this is a huge giant passage like an airplane, the width of the passage is probably close to 100 meters, and the height is more than 50 meters, the most surprising thing for Yu Chen is that the wall of the passage is not naturally formed, it is obviously artificially casting, the reason why it is said to be casting, is because Yu Chen actually saw many protrusions similar to metal on the wall, if you look closely, it looks like a handle switch or something. However, what shocked Yuchen the most was that Yuchen actually saw a lot of things similar to light sources on the passage star.

Yu Chen squeaked onto Lin Tianhua's shoulder and looked into the distance, the huge passage was probably more than a thousand meters. At the end of the passage there is a huge 'door'.

"Little one, is this what you're talking about?" Yu Chen couldn't help but send a voice to Shadow Snow hovering overhead.

"Of course not, you have to go forward, there is a big 'door' at the end of this passage!As soon as you get there, the 'door' will open naturally!" Shadow Snow's voice sounded in Yuchen's head.

Yu Chen couldn't help but be stunned for a moment, and then his heart beat a lot faster, because Yu Chen suddenly thought of a very impossible possibility.

After a burst of green light, Yu Chen recovered his human body and said, "You wait for me for a while, Bing'er, give me some fluorescent stones!"

"Yuchen, did you find anything?" Lin Tianhua asked. Yu Chen turned the extremely fast large piece of fluorescent stone handed over by Zikong Bing, and said, "I don't know, but I can try it, maybe we'll know in a while!"

Yu Chen took the fluorescent stone in his hand, and walked towards the few handle-like things he saw just now with his memory, walked for about thirty meters, and finally 'revealed' a wall in the light of the fluorescent stone, Yu Chen slowly stretched out his right hand, and a cold feeling came.

Sure enough, it's metal! Yu Chen secretly thought in his heart, although he didn't know what kind of metal it was, but Yu Chen was sure that it was metal. Yuchen slowly 'touched' along the wall, like a blind man 'touching' the elephant while moving forward, and finally used the fluorescent stone light to illuminate the handles.

"You all close your eyes!" Yu Chen suddenly turned around and shouted at Lin Tianhua and the others.

"What's wrong Yuchen?" Zikong Bing couldn't help but shout, thinking about walking at the beginning.

"You don't have to come here, just close your eyes! Maybe there will be a strong light soon!" Yu Chen shouted, hearing Yu Chen's words, although Zikong Bing and the others didn't know why, they still chose to believe Yu Chen and closed their eyes.

Yu Chen used the fluorescent stone in his hand to shine on the handles, and the corners of his mouth 'revealed' a wry smile, because those handles were clearly written, although he couldn't read the words, but Yu Chen still intuitively felt that there must be one in these handles that could control the lighting device above the passage.

"It's you!" Yu Chen chose a metal handle on the far left, and pressed it down gently, there was a crisp click, followed by a loud bang behind him, Zikong Bing and the others were so frightened that they quickly opened their eyes and looked back, only to see that the 'hole' that they had just entered was actually getting bigger at a strange speed. As the 'hole' widened, some of the earth and rocks began to fall downward.

"It doesn't seem to be this!" Yu Chen shook his head, and then pulled down another handle, as the handle fell, Yu Chen felt the ground under his feet tremble slightly, but then there was no movement, Yu Chen couldn't help but be stunned, and secretly said in his heart that the function controlled by this switch may have been damaged.

Glancing at the remaining seven or eight handles, Yu Chen turned around and said, "Don't open your eyes!"

Hearing Yu Chen's words, Lin Tianhua and the others, who opened their eyes, were curious, but they still closed their eyes again, Yu Chen stared for a few seconds, took a breath, stretched out his hand and pressed the handles one by one, and when he pressed to the penultimate one, the entire space instantly emitted a piercing sound, which made everyone cover their ears, and Lin Tianhua and Yu Xun'er opened their eyes directly with curiosity.

"Damn, this seems to be an alarm!" Yuchen Xinzong scolded secretly, stretched out his hand and pushed the penultimate one up, and easily pulled the last one down, and the last one fell at the moment it fell, and the entire space suddenly turned into a white mang'color', and Yuchen, who suddenly appeared with a bright light, couldn't help but quickly close his eyes, and Lin Tianhua, who opened his eyes, covered his eyes with his hand.

"What the hell is going on?" Yu Xun'er's eyes were suddenly pierced by the hungry light, and she couldn't help but shout.

"The light is too dim, and it is difficult to adapt to the sudden appearance of the light for a while, everyone slowly 'rubs' their eyes to get used to the current light!" Yu Chen's voice came into everyone's ears.

"Yuchen, what is this place, and these lights...... How do you know it emits light?" After everyone regained their vision, Yu Xun'er was the first to shout in surprise.

"Just now I turned into a blood god mink, and I saw those things that resembled magic lamps above, and I saw those handles on the wall, so I concluded that there should be a switch in them!" Yu Chen smiled as he pointed to the row of handles on the wall.

"I didn't expect you to be 'quite smart!'" Yu Xun'er couldn't help but laugh.

"The walls here seem to be artificially forged!" Lin Tianhua said as he walked into the wall and reached out to 'touch' the smooth metal wall. Dong Xuan took a closer look, and couldn't help but show a trace of surprise: "There is not a single gap in the connection, what a high forging process can be done!"

"This wall is actually forged from metal, I just don't know how hard it is, I'll try it!" Zhan Jiu said and took out his black blood dragon slayer from his spatial ring, and with enough strength in both arms, he rounded his arms and slashed at the wall. With a thud, the heavy sword slashed across the wall, bringing up a spark.

"How is this possible?" Zhan Jiu said with a look of disbelief, his black blood dragon slayer was not inferior to the ice blade of the Horcrux, although he did not infuse the fighting qi, but the ordinary Fan Tie was not like tofu in front of the black blood dragon slayer, but it was not too much worse, but at this time, under the sword of Zhan Jiuyi, only a trace of the thickness of a hair was left on the smooth metal wall!
