Zhang Lin felt pity in his heart and hugged Ye Yu tightly. In fact, he was also very cold and kept trembling.

The two hugged each other and kept warm through each other's body temperature.

While hugging each other to keep warm, both of them heard each other's pulses and heartbeats, and felt each other's shyness and shyness, but no one could bear to part.

This situation is still separated, so stupid, I have to freeze to death!

"Look, what is that?"

Suddenly, a strange light appeared in Ye Yu's eyes, and he raised his hand and pointed to the top of the cave.

Following Ye Yu's finger, Zhang Lin looked up and saw that on the top of the cave, there were wisps of green light appearing where the strong light did not shine. Soon, the green light showed signs of movement.

"This is a firefly!" Zhang Lin shouted in surprise. Unexpectedly, there are fireflies in this cave where birds do not shit. It was so amazing.

He freed up a hand to turn off the bright light of the Seven-Star God Stick.

In an instant, darkness returned to the front of my eyes, but it was not pure darkness. Countless green fireflies shone brightly. As the flashes accelerated, the darkness gradually diluted and became brighter and brighter. Like the stars in the sky, the fireflies flew away from the wall of the cave, slowly down from the top of the cave, flying in the air, changing into various forms.

As time goes by, there are more and more fireflies, mixed with yellow and light red in the green, making the entire cave a fluorescent ocean, setting off the stalactites and stalagmites, forming various strange shapes, extremely gorgeous and wonderful.

"It's so beautiful!" Ye Yu couldn't help but exclaim, forgetting the cold for the time being.

"Gurl~"

Zhang Lin heard the strange noise coming from Ye Yu's body and asked with concern: "Are you hungry?"

"Yes, aren't you hungry?" Ye Yu murmured as he looked up at his angular face and bright eyes in Zhang Lin's embrace.

"I'm hungry too!" Zhang Lin nodded.

"That would be great if I brought dry food!" A look of longing appeared in Ye Yu's eyes, and he even said something.

"Yes, but the dry food is all on Gao Lishi and Lu Junyi." Zhang Lin said with regret.

"Can we freeze to death and starve to death here?"

"No! I will find a way later." Zhang Lin comforted quietly.

The two of them gently rubbed each other's bodies with their hands to increase the temperature. Zhang Lin suddenly said excitedly: "I remembered it, I seemed to have sugar."

"Sugar?" A bright light appeared in Ye Yu's eyes.

Zhang Lin reached out and groped through his pocket. There were actually a few milk candies inside. Zhang Lin was overjoyed and took out all the milk candies, which were more than a dozen. He couldn't wait to peel off one and stuff it into Ye Yu's cold mouth.

Ye Yu was hungry and ate like a hungry chick. She opened her mouth and put the milk candy in it. After chewing it a few times, she swallowed it down her throat, and didn't even taste it.

"Give me one more!"

Zhang Lin peeled another pill and placed it in front of Ye Yu. She couldn't wait to open her mouth and put the milk candy in her mouth. This time she tasted it slightly carefully and tasted it was a milk candy. The Emperor once gave her the milk candy, and the taste was extremely sweet.

"It's so delicious!" After eating ten milk candies in total, Ye Yu's body regained a little vitality. She smashed her mouth and said with satisfaction. She couldn't eat it anymore, because she felt too sweet after eating too much.

Zhang Lin ate the remaining few pills and filled his stomach.

This thing can satisfy hunger, but it cannot keep the cold.

To keep warm, you must find materials to make fire.

However, in the entire cave, besides stalagmites and stalactites, there are fireflies flying all over the sky. Although these fireflies have the word "fire", they cannot produce fire and have no temperature. In addition, there are only some moss plants left, and the number of moss plants is very small. They are all pulled down, and there is not enough to burn them. The fire will be lit and burned.

What should I do now? Can I freeze to death here?

Zhang Lin suddenly thought that lime added water would heat up. And limestone must exist under the stalactite. Because stalactites were formed after water seeped into the limestone and condensed.

Thinking of this, Zhang Lin felt a little excited.

"Ye Yu, you can bear it for a while, and I will immediately get angry and get hot." Zhang Lin reached out and patted Ye Yu's soft shoulder, comforting with a smile.

"What did you use to make fire?" Ye Yu asked softly.

"See, I'm going to dig out the toad. The limestone is below. After watering it, it will heat up. After waiting, the entire cave will heat up." Zhang Lin raised his hand and pointed at a stalactite in front of him and said calmly.

Ye Yu raised her eyes and looked in the direction of Zhang Lin's finger. One meter away in front of her, a stone bell stood. The stone bell was about three feet high, and the base was two square, and the light of fireflies appeared in the shape of a toad.

"Can this work?" Ye Yu asked weakly.

"If you can do it, just wait!" Zhang Lin said firmly.

Ye Yu didn't say anything more. In her current situation, the only thing that can support her to survive is hope! If she loses hope, the flame of life will be extinguished at any time.

Zhang Lin reached out and patted Ye Yu's shoulders, then grew up, pulled out the magic sword from his waist, held it with his left hand, and began to slash wildly at the toad stalactite.

"Ding Ding Dangdang~" Mars flew around with gravel, which scared the fireflies and flew into the sky one after another.

During the slashing process, Zhang Lin's body temperature rose rapidly, and he even felt a sense of heat.

Ye Yu, who was sitting next to him, lost the support of Zhang Lin's body temperature and became colder and colder, like a white cat that was about to freeze to death, curled up on the cold stone slab.

Zhang Lin felt very distressed when he saw this, put down his sword, walked over and used his warm body temperature to transmit warmth to her to maintain her vital signs.

"Ye Yu, why don't you try to cut it a few times, so that it will get hot!" Zhang Lin suggested softly.

"But I have no strength at all now and can't even stand up." Ye Yu shrank in Zhang Lin's warm and gentle arms, and a look of regret and shyness appeared in his eyes, and he sighed softly.

"Well! I'll cut you again. Wen you later." Zhang Lin expressed his understanding. Ye Yu is like this now, and even has problems with his survival. How can he have the strength to cut stalactites? If she had that strength, she might be able to go out and destroy the men in black with one person.

Next, Zhang Lin waved his sword and chopped the stalactite for a while. After his body became hot, he walked back to hug him, warmed Ye Yu for a while, and passed the heat to the latter.

After repeated dozens of times, the toad stalactite was finally uprooted and a white limestone layer was exposed from below.

Without stopping, Zhang Lin continued to dig downwards and around. As he continued to dig, the area of ​​limestone became larger and larger. Finally, in front of him, he traveled a white pit that was ten feet square, full of limestone.

Seeing this situation, Zhang Lin scratched his head and felt that he had done a lot of useless work. He could just dig directly from the ground. Why did he spend so much effort to dig out the stalactite at all?

However, a large piece of limestone was finally dug out, and the result was still very beautiful! Next, just add enough water to the limestone pit, and the temperature of the entire cave can increase by at least ten degrees!

Although Ye Yu was quite excited when he witnessed Zhang Lin digging out the white lime layer, she still didn't believe that after adding water, the temperature of the entire cave could be significantly increased.

The question before us is how to divert water into the lime pit.

The distance between this lime pit is at least three meters away from the water surface. If you pick up water with your bare hands, how many trips will you have to walk? Zhang Lin was so tired that he couldn't get much water.

There was no water scooping equipment in front of him, except his white hands!

With that, Zhang Lin looked down at the two boots under his feet. The water contained in one boot is equivalent to scoop twenty times by hand, and the two are equivalent to 40 times by hand. In this way, using the boots to transport water is a relatively labor-saving and quick way than using the hands to pick water.

He took off his boots, walked down several stone steps, scooped two boots from the water below the stone cave, and then quickly walked to the edge of the pit and poured it into the pit.

Hiss ~

A hissing sound came from the lime pit, accompanied by a 2-point ray of heat rising up.

"Ye Yu, have you seen it? The lime is getting hot!" Zhang Lin shouted excitedly.

Hearing the sound, he also saw the heat swaying, but Ye Yu didn't feel the slightest heat, because the slightest heat was no less than a drop in the bucket for the huge cold cave. Even so, her eyes still showed an excited and joyful look.

She sees hope!
