Soon he made a discovery.

"Brother Feng, come here quickly!"

Liu Erwa shouted.

Lin Feng ran over and took a look. A cave just big enough for one person to pass through appeared in Lin Feng's eyes.

"I'll crawl over and have a look!"

Liu Erwa said and climbed in.

Liu Erwa, who learned a lot of scientific knowledge, became much more courageous.

There is a rope tied to him.

Lin Feng slowly loosened the rope at the entrance of the cave to prevent the rope from running too fast.

Ten minutes later, the rope moved twice.

Lin Feng immediately retracted the rope.

After more than ten minutes, Liu Erwa's head came out first.

"Brother Feng, there are very wide stone cracks outside. I don't know how far they are. Some places are narrow, some are wide, and some are bottomless..."

Liu Erwa said, picked up the phone, opened the photo he took and showed it to Lin Feng.

At this moment, there was a "crash" sound from the pool.
Chapter completed!
