I was about to reach for it when I heard Shirley Young calling out to me from behind: "Old Hu, go on." "When I looked back, Shirley Young threw me a pair of anti-gas gloves, and I understood what she meant, put the gloves on, and pulled the handle of the door with both hands, but the door did not move even if I tried to feed.

I took a look at the structure of the door, it didn't look like a heavy structure, I took a knife from my backpack and began to scrape the rust inside the crack of the door. Not long after, I scraped off all the rust that could be scraped off the cracks and joints of the door, put on gloves again, and grabbed the handle of the iron door.

When the iron door was opened, my spirit remained highly tense, for fear that the opening of the iron door would trigger some mechanism and put the three of us in danger again, but fortunately, when I opened the door, nothing out of the ordinary happened.

I pulled the whole door open with all my might, and suddenly, a dark entrance with a strong smell of the sea appeared in front of us, Shirley Yang and the fat man saw that there was no danger here, and they also followed, and we shone the flashlight into the hole, and inside it turned out to be a narrow trestle. On both sides of the trestle, the salty sea water shined on it, and the trestle was about 500 meters long, and the other end of the trestle was also a door.

"What the hell is this structure inside, how is it door after door, who built such a broken thing in the first place, I am tired after walking for so long!" The fat man said as he scolded.

"Chubby, persistence is victory, who swore just now that he would not give up halfway, and he will ...... now"

"Phew, I just said that I was tired, and I didn't say that I gave up halfway, is the fat man a person who doesn't talk much?" The fat man walked forward as he spoke, and stepped onto the trestle in one step, and walked forward along the trestle, followed by Shirley Yang and I, and also walked forward on the trestle, walking, and suddenly saw the fat man stumbling and falling to the ground.

"Lao Hu, this fucking has a mechanism! Let's get out! The fat man shouted.

Shirley Yang and I looked at the fat man's feet, only to see that a stone under the fat man's feet had sunk, as it sank to the bottom, only to hear a "bang" sound, the iron door behind us closed in response, this is really the more careful the more things happen!

Shirley Young and I ran over to pick up the fat man, ready to return to the iron gate where we had just entered, and find a way to open the iron door again.

"Old Hu, Shirley Yang, look, the sea around this trestle seems to be rising!" The fat man shouted.

Shirley Yang and I heard the fat man say this, and quickly looked down, and sure enough, the sea water suddenly seemed to be boiling, spitting bubbles and tumbling upward, as if crazy.

We hurried to the road we were going back to, but as we ran back, as we ran, I suddenly felt that my feet were empty, and another stone had sunk down, and the section of the trestle that led to the iron gate suddenly collapsed.

"I'm **, I'm stepping on the mechanism again!" I shouted.
