Fall into big hole

The wind stops. The rain stops. The lightning stops. All of a sudden, the sky turns into sunny sky. The environment becomes quiet.

"Look! The sunny day comes. It is amazing to have such a sudden weather change. It is unpredictable." Lily yells to us.

"Maybe the weather is controlled by those monsters. When they leave, the rain, the wind and the lightning leave." Sam makes a joke.

"It could be true. From the very beginning, those monsters used thunder storm to trap us in this hill. Then, they wanted to kidnap Lily and Mei. Thanks to our smart robots, those monsters could not realize their dreams. They had to abandon their plan and left. Then, they stopped the thunder storm." I make a joke and we all laugh.

"OK, the thunder storm is over. The surroundings are still in water. We cannot leave now. Let us stay here one day." The action leader suggests and we all agree.

We stay at the small island for the rest of the day. After enjoying the dinner prepared by Lily and Mei, we set a fire. We sit around the fire and enjoy chatting.

This night is a cloudless night. The sky is scattered stars while one moon hangs in the sky and another moon hangs just above horizon. The camping side is covered with silver moonshine.

Gradually, I fall into sleep.

When I am half awake and half asleep, I find that there are some small flashing points at the outside of the protecting wall formed by our smart robots.

I sit up and take a close look at those flashing points. I find that those flashing points are the eyes of wolf-size animals. Those wolf-size animals move around without any noises. Our smart robots just look at those animals closely without firing laser guns.

At this time, the other people still sleep soundly. Since there are noises from those animals, they are not waked up.

I watch those animals silently. Those animals try to get close to us but they are blocked by our smart robots. Since I have full confidence on our smart robots to protect all of us, I do not want to wake everybody up.

Those animals move around to try to break the defense line formed by our smart robots. Since those animals have no chances to move close to us, they disappear without any trances. I give a sigh of relief and sleep again.

This night, I have a nightmare. In my dream, a group of wolf size animals try to surround and attack us. During my escaping in high speed, I am scared to wake up. For the rest of the night, I cannot sleep anymore.

Next morning, it is an sunny day. During the breakfast, I tell everybody about the incident last night. I also let everybody watch the video recorded by a smart robot. After hearing my story and watching the video, they do not feel being scared. We all have full confidence on our smart robots to protect us. Everybody knows that there is no need to be panic as long as our smart robots protect us.

Suddenly, the land shakes. We all fall onto ground.

"Be careful! Another big earthquake! Lie down! Lie down!" The action leader reminds us.

At this time, there is a big crack at the bottom of the lake nearby. There is a huge whirlpool on the surface of the lake. This huge whirlpool sucks all the water nearby into it. The current changes its direction and rushes into the huge whirlpool.

"Look! The huge whirlpool sucks all the water into it." Lily yells to us.

The lake becomes a lake without water due to the huge earthquake. It becomes a basin.

"Amazing! The crack at the bottom of the lake must be huge. Otherwise, it cannot suck all the water into it." Mei yells to us.

"It is not a good news to us. The structure of the ground nearby is too soft. It is easy to become sinkhole. Let us leave here as quickly as possible for safe reasons." I tell everybody.

"If so, let us leave here quickly. If there is another earthquake, we could be buried here." Mei replies.

"OK, let us move quickly. Let us all move onto the backs of our smart robot tigers." The action leader tells us.

But, it is too late. There is another big earthquake. Almost instantly, we are all buried under ground. I lose my consciousness immediately.

I do not know how long it takes for me to recover my consciousness. I try to move my arms and legs. They are all OK. I turn on my portable torch. I can see that I am in an underground cave. I put an oxygen candy into my mouth to get more oxygen.

At this time, I see some more torch lights nearby.

"Who are you over there?" I yell to the lights.

"I am Mei!", "I am Lily!", "I am the action leader!". Very soon, everybody tells us his or her name. We are all glad to know that we are all OK.

We get together. After searching, it is unbelievable to know that all of our smart robots and robot tigers are OK, too.

Our torch lights shine the underground cave brightly. We discuss our next action plan.

"Listen! There is water running sound." Lily tells us.

"I can hear that, too. It is a running water sound. Is that useful to us?" Mei asks.

"It is useful to us. If we are near an underground river, we can save ourselves. Let us go to find the underground river." Tony suggests.

"OK, let us go together. No individual actions anymore, just for safe reasons." The action leader reminds us.

We connect each other by our connecting belts on our waists. In this way, if anyone falls into a hole, we can still hold this person without losing this person. We follow the sound of running water and move very carefully.

Very soon, we find an underground river.

In order to know the depth of the underground river, one smart robot goes to the edge of the river and extends its flexible arm into the river. A laser beam is emitted from its finger to measure the depth of the river.

"The river is not very deep, about five meters depth. The water is running. So, there should be an exit of the water. We can follow the river to the exit." I tell everybody after seeing the measurement of the smart robot.

"What do you mean by following the river?" Lily asks.

"You are right. If the water is not moving, it means that it is a underground lake. If the water is moving, it means that there should be an exit for the water to run. If we walk under water, maybe we could find the exit." I reply.

"Here is close to sea. Maybe the water runs into sea. Maybe we can find an exit above cliff." Replies Mei.

"Let us go. Even if an exit above cliff could be found, we still have a chance to escape to heaven." Replies Tony.

"OK, everybody has enough oxygen candies. There is no need for us to worry about oxygen supply. Next step, we need to find an exit. Let us try to find an exit from land first. If not, we can follow the river to find an exit to sea." The action leader tells us.

Very soon, we send our smart robots to search for exit of this underground cave. We and our robot tigers just wait at the original place.

Not very long, the smart robots come back one by one. As we expect, we cannot find any exit on land.

"OK, we have the searching result from our smart robots. The result is negative. We must follow the river to escape." Says the action leader.

"Hopefully, we can find an exit by following this underground river." I say.

"Right now, this is the only hope. But do not give up. I am sure that there is a way for us to escape to heaven." Replies Sam.

"OK, let us equip ourselves first. Everybody needs to put oxygen candy into mouth. Everybody should wear the total sealing uniform. Everybody should be connected with another person by the connecting belt. Let our smart robots walk in front under water. Let our robot tigers follow us immediately. Let us go in this pattern." The action leader gives his order.
