Half an hour later, Dong Sanmei drove back from the company, took the detonators and explosives out of the car, and brought a firecracker stick with her. She carried the explosives and the firecracker stick down to the foot of the mountain.

Dong Sanmei returned to her younger brother's side with explosives and detonators. She saw a mound of yellow earth piled up at the entrance of the cave. She was no novice in this area; she knew how to store explosives.

During the time that Third Sister was away, Dongqing was not idle. He found some loess, because you really can't store firecrackers without loess.

Dongqing loaded the detonators into the explosives and stored the explosives in the cracks in the rocks.

It's very troublesome to put explosives into the cracks in the rocks. Before you can put the explosives in, you have to fill the innermost and bottom cracks with soil and make sure the bottom is straight. Only then can you put the explosives in.

Dong Qing packed a large amount of explosives, with three layers of explosives in total. The first layer of explosives did not contain detonators, the second layer contained explosives with detonators, and finally, another layer of explosives was placed on top.

You really can't do without soil when you're tamping this kind of explosive. In the end, you fill the gaps between the explosive and the rocks with soil.

It took Dong Qing 20 minutes to store the explosives.

Electric detonators were used. Dong Sanmei had already laid down the firing line, and Dong Qing connected the main line and the detonator line before turning and walking away into the distance.

The siblings hid in a safe place, then pressed the blast wire onto the detonator. Dongqing first charged the blasting mechanism, and then rotated it in the opposite direction to detonate it.

With a loud boom, thick black smoke billowed up from the foot of the mountain.

The smoke from the blasting in the wild dissipated quickly. When Dongqing and her third sister approached, perhaps due to the weathering of the rocks, the blast had created a hole more than 1 meter deep, but it was still just a crack in the rock.

Dong Ermei helped her younger brother find loess soil, and Dong Qing used the same method to fire three shots in a row. After the third shot rang out, it blasted out a big hole.

Looking through the hole, it was indeed a natural cave.

"Third sister, the entrance is too small. Wait here for me while I go in and take a look."

After Dong Qing finished speaking, he took a flashlight and a bottle of mineral water, mainly intending to bring out a bottle of water from the cave for testing, and then climbed into the hole.

After climbing inside, he squatted down and looked around. The cave was about two meters high, and the walls were uneven.

At the bottom of the cave is a deep ditch from which warm water flows. Perhaps due to the effect of the water flowing at the bottom of the ditch, the bottom of the ditch looks very smooth.

Even a drop of water can wear away stone, so how could a flowing stream achieve such a feat over thousands of years? This natural ditch must have been there for countless millions of years.

He stood up and walked inside. The cave was very deep and had many bends. After walking about fifty meters in, the cave suddenly became taller and wider.

The further you go, the larger the cave becomes, and the more hot the steam becomes. The temperature here is much higher than outside. Even in winter, you won't get cold even if you go shirtless. In this season, Dong Qing is already covered in sweat.

After walking a while further, we found a mountain spring on the cave wall. The spring had a very large flow, but the water flowing out was cold. The water flowing out from inside was about 40 degrees Celsius. No wonder the water wasn't so hot when it flowed out. How could cold and hot water flowing out from here be hot?

After walking another 50 meters, the hot steam became increasingly intense, and suddenly a large pool appeared ahead. The pool was filled with hot water, and hot blood was flowing out from the pool. The water in the pool was already so hot that it was probably even hotter than the water at the spring.

According to Dongqing's guess, the water temperature at the hot spring outlet is at least 50 degrees Celsius, otherwise the water in the pool would not be so hot.

Dong Qing reached out and tested the water temperature. People who drink hot water could jump in, but people who don't would probably have a hard time.

Dongqing wanted to experience the effects of the hot spring, so he placed a flashlight on the stone wall, then took off his clothes and jumped into the water, which was more than 1 meter deep.

At first, the water was so hot that I couldn't stand it. After a few minutes, I felt much better, but I didn't dare to move around in the water. Even the slightest movement felt like being burned. The water temperature had reached the limit that the human body could tolerate.

Dong Qing soaked in the water for a full 20 minutes, sweating profusely.

He climbed out of the warm pool and stood on the rocks. Since he didn't have a towel, he could only let the water on his body dry.

However, the temperature inside the cave is so high that it's difficult to sweat and dry off.

He emptied and threw away all the water from the mineral water bottle, filled a bottle with hot water from the pond, then put on shorts and shoes, grabbed his clothes, and walked outside with a flashlight.

After taking a bath, I felt completely comfortable, unlike the feeling after bathing in a public bathhouse. I felt relaxed and light when I walked around.

Dongqing walked to the cave entrance and saw her third sister lying there. She said, "Why did you take so long to get in? If I had a flashlight, I would have run in long ago."

How could the older sister not be worried about her brother not coming out for so long? She had no idea what was going on inside the cave that had just been blasted open, and she was most concerned about her brother's safety.

"There's a hot spring inside, the water temperature is below 50 degrees Celsius. I took a bath there, so I came out late."

After Dongqing finished speaking, he handed the bottle and flashlight to his third sister.

He walked from inside to the cave entrance without breaking a sweat. He tucked his clothes under the entrance and then climbed out of the hole wearing only his shorts.

Dong Sanmei took the mineral water bottle her younger brother had brought out and felt it was very hot. She asked in confusion, "The water inside is so hot, why doesn't it get hot once it flows out? It can't cool down that quickly, can it?"

Dong Qing said, "The reason it's not hot is simple. There's a cold spring outside the hot spring. Hot and cold water meet and flow out together, and a large portion of it is cold water flowing out, so it's not that hot."

Looking at her younger brother's body and face, Dong Sanmei's eyes flashed with shock. She said, "How come your skin is so white after a bath?"

Dongqing said, "It's normal for skin to become moist and fair after a hot shower. Third Sister shouldn't have that kind of expression, right?"

Dong Sanmei said, "I still feel it's more of a hot spring. I'll send someone back to fully open the entrance so my siblings and I can go in and take a bath tonight and experience it."

Dongqing didn't take his third sister's words to heart. He said, "The water temperature inside is quite high, but as long as you can handle it, it'll be fine."

Standing outside the cave, you'll sweat quickly. After Dongqing sweats, he puts on his clothes.

The siblings walked towards the road while talking. When they reached the car, they saw his wife and children sitting on the grass. Dongqing said, "Yuzhu, what brings you here?"

Li Yuzhu said, "The hot spring is at the foot of the mountain. Isn't it easy to find your car once we get to the foot of the mountain?"

Li Yuzhu's words are true; the island is only so big, and once you know its exact location, finding it isn't difficult at all.

Li Yuzhu asked, "Has the cave entrance been opened?"

Dong Sanmei recounted the situation inside the hot spring cave, saying, "Only a small opening has been made, just big enough for a person to crawl in. I'll send someone over immediately to fully open the opening, and then the two of us can go in and take a bath tonight to experience it."

After hearing this, Li Yuzhu looked at her husband. His skin was noticeably fairer than before. She said, "Really? I'm looking forward to it."

Dong Qing's family drove back to the villa, while Dong Sanmei drove directly to the company.

The sun had already set, and the cave had to be opened before dark.
