Kai Hao hurriedly said: "I definitely can't compare with you, in this way, how about we run five more laps to sweat a little, and then go to my house to take a bath." ”

Chen Meng was stunned for a moment and said, "Go to your house to take a bath? ”

Kai Hao smiled: "It's troublesome for you to go home, and today I will take you to see the underground rock spring and natural bathhouse in my house." ”

Chen Meng suddenly became excited and said, "Sounds good, then let's run quickly." ”

Eight years ago, Kai's father, Lao Kai, wanted to dig a cellar under a room next to the kitchen to store food and wine, but he didn't expect to dig less than three meters before being blocked by a rock and couldn't continue to dig, he had to expand along the surface of the rock, and wanted to continue digging from the edge of the rock, if the rock is not big, he tried to move away, but he didn't expect that the surface of the rock was hard and very flat, and the whole room was dug down more than two meters, and he still didn't know how big the stone was, so he could only determine that the bottom of this room was only a part of the rock.

Lao Kai and Hongyu were stunned for a while, Kai Hao was only about four years old at the time, and he climbed to the rock surface every day along the soil dug by Lao Kai into an inclined plane to play.

At that time, Kai Hao heard the faint sound of flowing water in the rock.

But the other rooms are paved with stone brick floors, it is impossible to continue digging down like this, Lao Kai and Hongyu couldn't think of a way for a while, and then one day Hongyu suddenly said: "Hey, it's so big at this time, will our whole house be on stones?"

Lao Kai shook his head and said, "It's unlikely, the neighbors on both sides of us have dug cellars, and we haven't touched any big stones. ”

Ruby said with a smile on her face, "Then we can continue digging." ”

Lao Kai was in the prime of life, he was not afraid to exert his strength, but he didn't know how to dig, he didn't want to destroy the floor of the house to study a big stone.

Lao Kai said: "How do you dig it? The house has dug up, and there is still a dirt mountain in the yard that has not been dealt with." ”

Ruby said: "The room is not dug anymore, and if it is dug it cannot be used as a cellar, we dig in the yard, and if the stone is larger than the room, we will find the edge of it and make a cellar." ”

Lao Kai scratched his head with a questioning face, he didn't know how to find the edge of what Hongyu said.

Hongyu said: "I pondered, using that kind of hard thin wooden stick to smash into the ground little by little, if it touches the rock, the stick will not be able to fall, and then change the position until the stick can go deep into the ground and can not touch the stone, which means that I have found a place where I can dig down." ”

Lao Kai patted his thigh and said, "This method is fine." ”

There are a lot of this kind of hardwood sticks, Lao Kai immediately went to ask for some thumb-thick but extremely hard long sticks, stood on the wooden platform with a hammer and patiently smashed the pointed wooden sticks into the ground, the wooden sticks were smashed into the yard in advance The place was drawn in advance, and sure enough, the first few points of the wooden sticks were smashed to a depth of about two meters, and they were blocked by the rocks and could not go deeper.

Soon Lao Kai found that half of the courtyard was covered with the big rock.

He felt a little incredulous because he had never seen such a huge rock.

Naturally, he couldn't imagine that the house he built was actually on a big rock.

When the courtyard wall was almost detected, Hongyu was about to give up what to do with the cellar, Lao Kai suddenly lowered his voice excitedly and shouted: "Hongyu come and see, the stick has smashed in." ”

In the innermost corner of the courtyard wall, you can finally avoid the stones, Lao Kai hummed happily and began to dig into the ground, and found that he dug more than two meters deep, and he was digging close to the edge of the big rock, on one side was the stone that I don't know how thick, and on the other side was the courtyard wall, Lao Kai dug down a full six meters in an area less than two meters wide and about three meters long, starting from two meters deep, the rock occupied a whole side, which seemed to have a slight arc, but basically it was flat and occupied the entire side wall to six meters underground.

The surface of the stone is very smooth and very hard, Lao Kai took the metal drill to see if he could smash it, and found that with all his strength, the sparks shot indiscriminately, and there was almost no damage to the surface.

Hongyu is now looking down at a deep cave that is only more than one meter wide and three meters long, and feels that it is really inappropriate to be a cellar.

Lao Kai was covered in broken earth and stood below with an iron pickaxe, looking at the huge stones in front of him, and suddenly looked up at the red jade looking down above, his face full of doubts.

Hongyu hurriedly asked, "What's the matter?" or forget it? The place is too small, and it is all occupied by big stones. ”

Old Kai pointed to the smooth surface of the stone and said, "Why is there a sound in it?"

Hongyu was startled and said, "Is there a sound in the stone?"

Kai Hao told Chen Meng how his father, Lao Kai, found that the big stone was actually empty, connected to the source of spring water in the unknown place, and there was actually a naturally sunken rock bath.

Chen Meng said: "Kai Hao, this is to be kept secret, right? I haven't heard you say it before." ”

"Of course, my mother has long said that they can't let outsiders know, because they can hide inside during the war, and it should be very safe. But the place is not very big, and there is no more place to help others, so it is simply kept secret. It's also rare for our own family to go down and take a bath in the spring water. ”

Chen Meng said: "Then you told me that it wasn't a leak?"

Kai Hao said: "Tell you that it's okay, you can't tell the second person anymore, including your parents." ”

Chen Meng nodded and said, "Okay." I can keep secrets. ”

The two had already run back to Kai Hao's house along the quiet street at night, and Hongyu had already taken Xiao Xuan to sleep.

Kai Hao took a towel and a change of clothes and took Chen Meng to the backyard, the backyard built a long storage room against the courtyard wall, which looked very inconspicuous, opened the door, and there were all kinds of tools and sundries in the narrow space inside, the whole utility room was like a passageway, only less than two meters wide, and when there were two meters away from the innermost wall, there was nothing unusual to see.

Kai Hao bent down, put his fingers into the two round holes in the thick wooden floor, and with a force, turned up a wooden board one meter wide and two meters long to the right, and leaned against the wall on the right, revealing a rectangular entrance with neat steps to walk down.

A crystal lamp was placed on the wall next to the steps, so it was clear that the steps were very long, and Kai Hao walked down and let Chen Meng follow.

Kai Hao walked into the entrance, turned around and said, "Put the plank down and cover the entrance." ”

Chen Meng's shoulder height was still outside the entrance, and with a sigh, he grabbed the wooden board and covered the wooden board back in place as the person walked down.

Although the inside is not wide, but Chen Meng is so tall and does not look cramped, walking down the steps for about ten meters, Chen Meng has already heard the faint sound of running water, Kai Hao has already stood at the entrance of the huge stone bathroom, turned around and smiled and waited for Chen Meng to walk down.
