Moreover, high temperatures also have a significant impact on plant growth.

Zhao Hangjun adjusted his glasses, his expression grave, and continued his explanation: "Soil moisture evaporates rapidly under high temperatures, and crops may wither and die due to lack of water. Animals are also prone to heat stress, which can be life-threatening in severe cases."

Zhao Hangjun's explanation of the science made the atmosphere in the live broadcast room increasingly tense, and the viewers expressed their concerns in the barrage.

Lu Fan scratched his head, looking helpless, and said, "God really knows how to pick the right time. He had to do this right when we just started planting. Isn't this deliberately making things difficult for us?"

An Lan, however, remained remarkably calm, gently reassuring him, "It's alright, we have a spring, so we don't need to worry about the water. As long as we take proper precautions, we'll be fine. There's always a way out, we'll definitely get through this."

With that, Lu Fan got up and went to the kitchen to prepare lunch.

As he walked, he muttered to himself, "On such a hot day, I need to make something refreshing, otherwise I won't be able to eat at all. Food is essential for life, no matter how hot it is, I still have to eat properly."

Suddenly, his eyes lit up as if he had discovered a new continent, and he excitedly shouted, "Anlan, how about I make you a blueberry smoothie? I guarantee it will cool you down, make you feel refreshed, and instantly chase away this heat."

An Lan's eyes lit up, and her face beamed with anticipation: "Great! I haven't had a smoothie in ages. Just thinking about it makes me feel cool."

Lu Fan quickly got to work, first taking out a clean block of ice from the storage room.

The ice shimmered in the sunlight, like a precious crystal.

He put the ice into a stone mortar and began to crush it with a pestle.

The way he pounded the ice was quite rhythmic; the ice blocks made a "clinking" sound as he pounded them in the stone mortar, like playing a unique percussion piece.

An Lan watched from the side and couldn't help but laugh out loud: "With your stance, anyone who didn't know better would think you were practicing some kind of peerless martial art. You might just unleash a set of the Eighteen Subduing Dragon Palms in the next second."

Lu Fan chuckled and joked, "This is the long-lost secret manual of the Frost Palm. Zhang Wuji was crippled by this skill. Once I master it, even the high temperatures will be afraid of me."

After crushing the ice into small pieces, Lu Fan took out the preserved blueberries from the storage room.

These blueberries are plump and shiny purple, like precious gems, exuding an enticing fruity aroma.

He put the blueberries into the mortar and stirred them with crushed ice, muttering to himself as he stirred, "Blueberries and shaved ice are a perfect match, sweet and sour, plus this refreshing texture, wow, just thinking about it makes my mouth water. Once it's done, it will definitely be a delicacy."

In no time, a delicious blueberry smoothie was ready.

Lu Fan carefully ladled the shaved ice into a wooden bowl, inserted a homemade wooden spoon, and even arranged it in a nice way before handing it to An Lan. He bowed slightly and said like a gentleman, "Honorable guest, please enjoy. I hope this shaved ice will help you beat the summer heat."

An Lan took the shaved ice, took a small sip, and her eyes instantly narrowed into slits as a satisfied smile spread across her face: "Wow, this is so delicious! Lu Fan, you're a genius. I never expected to find such a delicious shaved ice in this wilderness."

Lu Fan raised an eyebrow smugly, a confident smile spreading across his face: "Of course, don't you know who I am? I'm a hidden culinary master, nothing can stump me."

The two sat on bamboo chairs, eating shaved ice while discussing ways to cope with the high temperatures.

The bamboo chairs swayed gently with their movements.

“I think we should fill all the containers that can hold water, just in case. Water is the source of life, and it can save lives in critical moments,” Lu Fan said, his eyes revealing determination.

An Lan nodded in agreement, then added, "Yes, we also need to prepare a shady place for Dahei and the others, and put plenty of water in it. The animals can't stand such hot weather, so we have to take good care of them."

The two of them talked back and forth, taking into account every detail, from food reserves to protective equipment and the care of the animals.

In the live stream, viewers' comments scrolled by like snowflakes.

"Ahhh, this blueberry smoothie looks so tempting! I want to eat it too. I can almost feel the coolness through the screen."

"You two really know how to enjoy yourselves. This heatwave was driving me crazy, and you were here eating smoothies. But seeing how calm you are, I feel a little relieved."

"What's there to be afraid of? With Brother Lu here, nothing will go wrong. Brother Lu and Sister Lan will definitely be able to figure out a way to deal with it. I have confidence in them."

After finishing their shaved ice, Lu Fan and An Lan immediately got to work.

They found a well-ventilated corner next to the shelter, where there were several large trees with lush foliage, like giant parasols.

They built a simple shed with bamboo and leaves, providing a place for Big Black and the other small animals to escape the summer heat.

Big Black seemed to sense its owner's care, wagging its tail and happily circling around in the shade, occasionally running over to rub against Lu Fan and An Lan's legs.

After everything was arranged, Lu Fan stood in front of the shelter, hands on his hips, his gaze firm, and said thoughtfully.

"I need to go back to the fissure I discovered earlier and collect more saltpeter to have on hand. Saltpeter is very useful; I can make more ice later. With ice, we can not only cool things down but also preserve food."

An Lan nodded in support and said, "Let's go together. More people means more strength, and two people can look out for each other."

Lu Fan patted Big Horn's neck and said with a smile, "Big Horn, Big Horn, we're counting on you to do our job today. Let's go move the 'treasure'. You're our right-hand man, so don't let us down."

Big Horn seemed to understand him. It shook its head and let out a low growl, as if responding to him or encouraging itself.

After walking for more than an hour, they finally arrived at their destination.

Lu Fan brought the giant horn to the crevice and could even feel the cool breeze gushing out from inside, as if it were a breeze blowing from another cool world.

"Anlan, I'll go down first. You stay up here and meet me. If anything happens, just shout for me."

As Lu Fan spoke, he tightened the ropes around his body, preparing to descend into the crevice.

After saying that, Lu Fan skillfully crawled into the crevice.

The deeper you go, the larger the gap becomes, eventually forming an underground cavity.

It was dark and damp inside, filled with a mysterious atmosphere.

He slowly walked to a relatively spacious area where there seemed to be a lot of saltpeter, which shimmered white in the dim light.

Lu Fan rubbed his hands together excitedly, his eyes sparkling with joy, and said, "So much saltpeter, it's practically a treasure trove! We'll have to dig up as much as possible this time. With this saltpeter, we'll have a secret weapon to combat the high temperatures."

He picked up his tools and began carefully collecting saltpeter.

Every now and then, An Lan would call out from above to check on Lu Fan's safety: "Lu Fan, are you alright?"

“I’m fine, everything is normal!” Lu Fan always responded loudly.

The soil here is mostly sand and gravel, with saltpeter stuck inside, making it relatively easy to mine.

After some effort, Lu Fan filled two large baskets with saltpeter.

Lu Fan skillfully climbed up and laboriously lifted the two baskets up.

Just then, a wilderness survival announcement rang out from the sky:

[Wilderness Survival Announcement]

Chinese contestant Lu Fan triggers a 10,000-fold return.

Saltpeter 54*

Upon hearing the news, the two were both surprised and delighted.

Lu Fan jumped up excitedly: "That's great! So much saltpeter, enough for us to use for a long time."

An Lan also smiled happily: "This is too lucky! It seems we were really well prepared this time."

Then An Lan said, "I'll go look around and see if there are any plants that can clear heat and reduce internal fire. I'll pick them and make tea. Drinking some cool tea can quench thirst and reduce internal fire."

Then Lu Fan led Da Jiao and followed her. They traversed through the mountains and forests, their eyes like searchlights, carefully searching for useful plants.

They didn't miss a single leaf or a single flower.

[Honeysuckle Discovered]

"That's honeysuckle, isn't it?" Lu Fan casually reminded An Lan, a slight smile playing on his lips.

"You have a good eye! These honeysuckle flowers are growing so lushly; we can definitely brew a big pot of delicious herbal tea with them. With them, we'll feel much more comfortable in this hot weather." Anlan happily began picking them, her movements practiced and swift.

During the harvesting process, Anlan also encountered some other herbs. Based on her knowledge and experience, she was able to identify which ones could be used in hot weather.

"This is mint. It smells refreshing. I'll pick some to take home. Mint tea is refreshing and perfect for summer." She said as she put the mint into the bamboo basket.

Before we knew it, the sun was gradually setting in the west, and the sky was tinged with orange-red sunset clouds, like a beautiful painting.

Lu Fan and An Lan returned to the shelter with a wealth of knowledge and experience.

The two looked at each other's work and smiled with satisfaction.

The bamboo baskets were filled with various herbs, and the hampers were piled high with saltpeter; these were their "weapons" against the high temperatures.

"What a fruitful day! With these saltpeter and herbs, we're much more confident in fighting the high temperatures," Lu Fan said with a smile, his face beaming with pride.

An Lan nodded in agreement: "Yes, as long as we work together, we will definitely be able to overcome this difficulty. No matter what difficulties we encounter, we can overcome them together."

Of course, this is not enough preparation.

They were unsure just how extreme the temperatures would be during the extreme heatwave.

If it's too hot to go out, then you should prepare some food just in case.

During his break, Lu Fan decided to knit two hats to shield himself from the sun.

He first picked up the dagger and skillfully shaved a pile of bamboo strips, each one of which was shaved to a uniform thickness.

Then they removed all the burrs from the bamboo strips, their movements meticulous and careful.

His fingers moved nimbly between the bamboo strips, as if playing a beautiful melody.

Then, he wove them together by overlapping them.

Once you find the pattern, this isn't difficult to learn.

As Lu Fan wove, he recalled watching his grandfather weave bamboo baskets when he was a child. Those warm memories made his movements even more skillful.

In no time, a delicate bamboo hat was completed.

Lu Fan put it on his head and said to An Lan with a smile, "How is it? My skills are pretty good, right?"

An Lan smiled and nodded: "It looks beautiful. You are really skillful."

"Hehe, have you ever heard the saying, 'One of the eighteen oddities of Yunnan is using a straw hat as a pot lid'? I've worn this since I was a child."
