Variety show live broadcast: I take celebrities to survive in the wilderness

"Teacher He, can we use the tools next to you?" asked Zhou Chuang, a survival expert from Group E.

"You can use them. For each thing you use, you will have to add thirty seconds to the total time it takes to make a fire. There are no restrictions on anything here. You can use as many as you want." He Jiong nodded with a smile.

"Does anyone have any other questions? If not, the staff will start counting the time for each of you." Seeing that no one had any more questions, He Jiong nodded to show that they understood the rules.

He immediately announced the beginning of the first change.

At this time, five staff members came to the temporary location set up by the five groups with a stopwatch.

"Do as I tell you, the faster the better!" Li Yinsheng selected a Swiss knife from the tools prepared by the program team and went to explore the edge of the island.

As for the tools for making fire prepared by the program team, there are many, including Swiss knife, light bulb, traditional fire-making kit, one-person portion of tinder and other items.

Both Group C and Group E chose the traditional fire-making kit. The kit provided by the program team included a hard wooden stick as a drill rod, a dry and flammable wooden board as a fire board, and a small piece of tinder to guide sparks.

After getting the tools for making fire by rubbing two sticks together, both groups seemed full of confidence. They sat around in their respective temporary areas and began the challenge of making fire.

Groups BD did not choose the items provided by the program team. Like Group A, the team members scattered around the island looking for tools to make fire.

"I found tinder, a lot of it, enough for the six of us." At this time, Zhao Liying shouted loudly.

"I've also found a suitable fire board." Zhang Yixing's voice came over.

Coincidentally, Li Yinsheng also found two wooden sticks suitable for making bowstrings and drilling wood to make fire. They were of the right length, dry and tough.

In less than two minutes, they found suitable materials for making bowstrings, drilling wood to make fire, and tools to start a fire.

Making bowstrings and drilling wood to make fire requires patience and skills. Li Yinsheng and his team had a clear division of labor. Li Xiang was responsible for finely polishing the wooden stick to make one end sharp and smooth to serve as a drill bit.

Li Yinsheng untied his shoelaces and tied them to both ends of a resilient branch to serve as a bow frame.

The wood used to make the fire, also called the fire board, has a V-shaped notch cut in the center to allow a knife or other sharp object to enter.

Wrap the bowstring around the tinder stick once, with the middle of the string wrapped around the stick so there is room to move the stick back and forth.

"Great! The fire was ignited successfully, let's continue with the next one." At this time, cheers came from Group E. It turned out that the master of Group E successfully ignited the fire using the primitive tool of drilling wood to make fire.

Then, Brother Hu from Group C also successfully lit a fire using the primitive fire-making tool of drilling wood.

People from both groups succeeded in lighting fires one after another, which stimulated Group B and Group D. These two groups neither chose the primitive method of drilling wood to make fire, nor did they choose to use a bowstring to drill wood to make fire like Li Yinsheng and his team.

Instead, they chose the more modern but equally skill-intensive method of focusing sunlight with a light bulb. Under the scorching sun, one member of Group B held a light bulb and carefully adjusted the angle and distance, while another assisted by building a tiny fire with hay and thin wood strips. The sunlight passed through the light bulb and gathered into a bright and hot beam that shone directly on the hay.

"Come on! It's almost there!" Group D used friction to make fire. They chose two pieces of bamboo strips, put some tinder in the middle, and rubbed them back and forth to start a fire.

"It's done. Let me start a fire first." Li Yinsheng spent nearly two minutes to finish making the bowstring and fire by drilling wood.

Li Yinsheng pulled the bowstring quickly and rhythmically, causing the drill to spin rapidly on the drill board. Each pull was accompanied by a slight "squeaking" sound, which was the sound of friction between the wood.

Using a bowstring to drill wood to make fire not only saves time and effort, but is actually a clever application of the principles of physics. The friction generated by rapid rotation concentrates the heat of the wood to one point until it reaches the ignition point.

As Li Yinsheng continued to move, the wood chips on the drill board began to become finer and the color changed from light yellow to dark brown, and a faint burnt aroma filled the air.

The small pit on the drill plate began to smoke, and then a wisp of green smoke rose up.

Seeing this, Li Yinsheng stopped drawing the bow. He held a piece of tinder in his left hand and poured the sparks on the fire board onto the tinder. Then, Li Yinsheng blew on the sparks, and in a short while, he lit the tinder. Then he added firewood and soon lit a fire.

"I'll do it." After seeing the fat girl successfully make a fire, Li Xiang immediately took the bowstring from Li Yinsheng's hand, drilled wood to make fire, and began to spin it quickly.

However, people in the other four groups also succeeded in making a fire one after another, but no one in the ED group, which succeeded in making a fire first, succeeded again.

The bowstring fire-making method is highly efficient and convenient. Pulling the drill shaft quickly can generate enough friction and heat to ignite flammable materials, thus successfully making a fire. Compared with other methods, the bowstring fire-making method is easier to operate and can make a fire in a shorter time.

It took less than twenty seconds for Li Xiang to pull the bowstring and blue smoke soon came out of the fire board. Then he poured sparks onto the tinder and blew it to ignite it successfully.

"I'll do it!" Huang Xiaoming took over, and Zhang Yixing prepared to be the next one to start a fire.

.........

"Damn! Group A is really fast at starting a fire. Three of them succeeded in starting a fire, and it took no more than a minute."

"Upstairs, the bowstring fire-making method is efficient and convenient, much faster than the old-fashioned fire-making method of drilling wood."

"The members of Group A work really well together. It seems that Group A is the most likely to have a chance to start a fire in the first round."

"Groups E and D are in trouble. It takes a lot of effort to make fire by drilling wood together. The girls in these two groups simply don't have the skills and physical strength to complete the fire. Why don't the survival experts in Group E consider the situation of girls?"

"Indeed, Group A's strategy is obviously more comprehensive. It not only takes into account the efficiency of skills, but also takes into account the gender and ability differences within the team. Such teamwork is the key to survival challenges."

"It seems that this time the changes are not only a display of individual skills, but also a test of teamwork and strategic planning. Group A's fast and comprehensive approach undoubtedly gave them an advantage."

"Just because Group A is ahead in this variable doesn't mean they will always be ahead. Don't forget, survival challenges involve many other skills, and other teams may be able to shine in other areas."

After seeing the first round of the variable fire-making, the audience watching the live broadcast left messages on the barrage and had a heated discussion. Some viewers praised the tacit cooperation of Group A, believing that they showed true team spirit; others expressed sympathy for the plight of Groups E and D, encouraging them not to give up, after all, the survival challenge has just begun and everything is possible.
