In the early hours of the morning, the Dodge quietly drove into the Rock Beach Pier, which is across the sea from Wolhua Island.

Paul had rented a white speedboat with great horsepower beforehand, parked right on the side of the pier, near an abandoned cruise ship, floating up and down the coast.

The two men packed their belongings and jumped into the speedboat, and Paul crouched down at the bow of the boat to untie the twine tied to the iron post.

The speedboat turned around and left the dock with the twinkling yellow lights and headed for Wolhua Island.

About forty minutes later, in the darkness, the two of them saw the vague appearance of Yuehua Island. Paul turned down the sound of the engine, turned off the lights on the boat, and the speedboat slowly approached the island.

Bypassing the bright light of the lights, the speedboat silently approached the black-brown reef on the north side of Wolhua Island, and the large and small abrupt shores.

The sea crashed against the reef, rattling and splashing on the face, giving it a salty smell.

The two jumped out of the boat, dragged it to the reef, tied the rope tightly to the reef, and cut some shrubs from the shore to cover the boat.

Bai Lotian took out the drawings he had drawn, looked at them, and then put them back in his pocket. The two of them strapped their backpacks and walked along the bushes next to the reef.

"Are you sure you have this place?" asked Paul.

"I'm sure. I'm afraid that it will be considered a cover-up later, so maybe that's not enough. Bai Lotian carefully observed the terrain and direction as he walked.

"God willing!" Paul whispered.

The pebbles under their feet were scattered and the bushes were dense, and the two of them walked and stopped, and Paul reached out from time to time to pluck the branches and leaves.

The lights on the high wall flickered overhead from time to time, and even the tapping sound of the sentry's leather boots could be heard, and Bai Lotian understood that he was almost at the position of the dark passage.

"Slow!" Bai Lotian reached out and grabbed Paul's clothes, he poked his head out of the bushes, came to the junction of the beach and the reef, crouched down, and stretched out his hand to pull there.

Paul also walked over and looked down at the place, and there was nothing out of the ordinary.

Bai Lotian looked up at the high wall, and then a lot of it, and there was a narrow inlet in front of him.

"This should be it. Bai Lotian said, "Is it buried by sand?"

Paul took out a knife, handed it to Bai Letian, and said, "Mr. Zhang, try this." ”

Bai Lotian was stunned for a moment, and immediately reacted, his current name is "Zhang Dong", and his appearance has also changed.

Bai Lotian took the sharp knife, knelt next to a large black-brown reef, stuck the sharp knife into the sand under the reef, and kept pulling out the sand and piling it up behind him.

Suddenly, a bright light shone on them, "Is there anyone? Who's where?" The light of a flashlight shot from the high wall dozens of meters away from them.

The two of them were startled, and hurriedly hid behind the reef, silently until the light left, and the sentry could not be heard.

"Will it be discovered?" Bai Lotian said, touching his chest.

"Don't be afraid of those who scare. Are you sure this is the place?" Paul looked at him quizzically.

Bai Lotian took out the drawing, spread it on the sand under the reef, turned on the mini flashlight, covered the light with his hand, leaned down, and almost stuck his face on the drawing.

Paul was close to his shoulder, his eyes fixed on the drawing.

"I'm sorry, buddy, I was wrong, I have to go around the inlet in front of me. ”

Paul smacked his chest, snorted, pouted, lifted his backpack, and walked straight on.

The two walked around the reef, through high and low bushes, stepping on gravel, and wading through a knee-deep inlet to the rocky shore.

Several reefs were stacked on top of each other, covered with moss, slippery and greasy, and there were a few crabs in the crevices of the rocks.

"This should be it. Bai Lotian touched the reef and said.

Paul took out his flashlight and turned it around carefully, not seeing where the tunnel was.

Bai Lotian picked up a pebble and tapped the reef as he walked, sometimes lying on it and listening for a while, trying to find the place where the echo was empty.

Bai Lotian pointed out the suspicion to Paul, and Paul chose a pebble to take advantage of and knocked on it.

"No, no, no. Paul became more and more agitated, "Could it be a mistake, or that there is no such hole at all?"

Bai Letian was also playing drums in his heart, after all, he only found it from the information, and no one could guarantee it.

Paul was a little tired, sat on the sand and lowered his head, "Maybe we were wrong." ”

Bai Lotian sat beside him, bowed his head, and looked depressed. "Is it really wrong. ”

"I'm going to go back today in vain. Paul looked up at the foggy sky and sniffed.

Bai Lotian turned around and slammed the reef behind him, and heard a "bang" sound, which was empty and far away.

The two froze, and then jumped up, "Is this it?" said in unison, Paul's eyes shining.

The brown reef was no different from the one next to it, and with the bright light of the flashlight, I could still distinguish some abnormalities.

The reef is made up of three large stones joined together, and the traces in the middle have disappeared, only the concave part can be seen, and the surface is a wet dark green moss that blends with the brown reef and exudes the fishy smell of rotting seafood.

Bai Lotian stretched out his palm, patted it lightly on the surface of the reef, sometimes leaned over to listen to the different echoes, and finally, smiled. He took out a small hammer and slammed it down against the place where the mark had been made.

As the surface of the reef peeled off, the ground was piled with cement-like hard lumps, but in a few minutes, a round hole appeared on the reef in the middle, allowing one person to enter.

Paul grabbed Bai Lotian's hand, "Let's go!"
