The First Day

"In the wild, securing a source of fire is the guarantee of survival, and learning how to obtain it is a mandatory lesson for any survivor.

First, find a thick piece of hardwood to serve as the spindle and a flat piece of softwood. Connect the hardwood to a flexible branch using vines, then sharpen a wooden tip. Drill a shallow hole into the board and carve a small notch next to it.

Insert the hardwood into the hole, press down on the top with the sharpened tip using both hands, and move the bowstring back and forth to make the hardwood spin at high speed. Keep the tip steady and apply pressure; once sparks appear in the notch, immediately cover them with tinder and blow gently to encourage the flame.

In this way, you obtain the most precious source of fire."

Ying held the fire source he had just created using the bow-drill method in one hand, while resting the other on his forehead to act cool.

"Ying, the fruit and vegetable soup is ready. Want a bowl?" Hamaguchi held a steaming bowl of soup and handed it to Ying.

Ying looked up and saw that Kanzaki and the others had already started a campfire at some point.

"Impossible! How did you guys get a fire going so fast!? The soup is good, though." Ying took a sip and questioned them.

"We just dug a lighter out of a wild village." Hamaguchi held up a lighter, which even had a picture of a gal on it.

"You guys broke the rules!"

Although they claimed to have found a village, it was actually just two or three dilapidated shacks with almost nothing inside; the only useful thing was this lighter.

"Byakuya-kun, I heard you participated in a summer camp before. The girls are having trouble setting up the tents, could you come over and help?" Ichinose walked over and asked Ying.

"What? Who said I went to a summer camp? That's pure rumor! I clearly participated in my own World Extreme Survival Challenge and achieved the great result of surviving 10,086 days. Setting up a tent is a piece of cake." After saying this, Ying rolled up his sleeves and headed toward the girls' tent area.

As a survival master, Ying successfully helped the girls set up their tents and returned to the boys' area feeling quite self-satisfied.

"Tetsuya, which tent am I sleeping in?" Ying asked.

"You're sleeping there." Hamaguchi pointed to a tree next to the boys' tents.

"What do you mean? Tell me which tent I'm in." Ying urged.

"Ying, Class B has four tents in total, and each tent sleeps five people. However, there are 21 boys in Class B. You get what I mean, right?" Hamaguchi said with a smirk.

Ying's pupils constricted. What!? How could this happen!

"Wh... what!? Am I, am I actually! Going to have to sleep with the girls!?" Ying exclaimed.

"What are you talking about? I meant you have to sleep outside!" Hamaguchi corrected him, speechless.

"I hereby issue an order: choose one boy to go sleep on the girls' side. Come here and play rock-paper-scissors now," Ying declared.

"Don't try to brush it off. There's no space left for you," Hamaguchi said, exasperated.

"Tsk... Tetsuya, where are you sleeping?" Ying wrapped his arm around Hamaguchi and asked.

"What, what are you doing?" Hamaguchi had already guessed what Ying was thinking, so he changed the subject.

"So, it's the first tent, then?"

"Huh? How did you know?"

"OK, your bunk is mine now." Ying finished his sentence and dove straight into the first tent.

Hamaguchi realized he had been tricked and wanted to slap himself twice.

In truth, Hamaguchi had only meant to play a joke on Ying, but in the end, Ying squeezed in with the others in the first tent to sleep.

"Alright, basic living arrangements are settled. Next, let's divide into groups and explore this Uninhabited Island!" Seeing that everyone in Class B had set up their tents and settled in, Ichinose proposed this.

"Great! We'll follow Honami's lead!"

"I want to be in a group with Ichinose!"

"Me too!"

Seeing everyone's enthusiasm, Ichinose smiled shyly and finally divided Class B into 10 groups of four people each.

"Byakuya-kun, I'd like to ask your group to scout the situation of the other classes. Can you do that?" After Ying formed a group with his best buddies, Ichinose gave them their mission.

As a qualified White Room assassin, Ying considered himself very familiar with scouting and intelligence, so he agreed without a second thought.

"Ying, do you know where the other classes are?" Shibata asked, looking at Ying's confident expression.

"Of course," Ying said, crossing his arms as if it were obvious.

"Then where are they?" Shibata continued to ask.

"Class A is in a cave, Class C is on the beach, and Class D is by a small stream," Ying replied.

"Uh... and specifically where?" Beppu asked.

"Well, obviously..." Ying had intended to tell them, but realized he didn't actually know. His memories from his past life only allowed him to recognize the scenery around the various bases, but he had no idea where they were located on the island.

"Let's go. All roads lead to Rome," Ying said, and continued walking forward.

Everyone: ...

"Ying, look, there are people ahead." Hamaguchi noticed something unusual and whispered to Ying cautiously.

Everyone crouched down and moved stealthily, looking where Hamaguchi pointed. They discovered that it was actually the Class D camp; they hadn't expected to find it so quickly.

"Don't make a sound. Our mission is to scout, and you can't expose your presence while scouting," Ying whispered a reminder to the group.

"Byakuya-kun, what are you all doing here?" The four of them looked up in surprise; the people who had arrived were none other than Sakura and Ayanokoji, who were returning from their own exploration.

"The radius of this oak tree's trunk is about two meters, and the bark is rough; it looks like it has at least several decades of history. Kouiku really has a deep foundation," Ying praised the oak tree in front of him.

The members of Class B were stunned for a moment, but then they all reacted and began to praise the school's scenery in unison.

"Is that so? The base of Class D is just ahead. Byakuya-kun, would you like to come and take a look with me?" Sakura seemed to have made a huge decision as she invited Ying.

Ying: There's such a good thing? Someone is actually inviting a scout to their main camp?

"Sure!" Ying agreed immediately without a second thought.

"Ying, you animal! You're trying to sneak off!" Hamaguchi gave Ying a heavy elbow strike and pointed at him, cursing.

"Confess honestly, when did you hook up with a girl from Class D?" Beppu also came over and put Ying in a headlock.

"Ugh, cough, cough... I don't know... what you guys are talking about," Ying responded with difficulty.

"You've misunderstood. I, I am Sakura Airi, and I'm just an ordinary friend of Byakuya-kun!" Sakura hurriedly denied it with a blushing face.

Afterward, the members of Class B visited the camp of Class D, and their most intuitive impression was that it was poor.

In exchange for visiting the camp of Class D, Ying and the others also shared the location of the Class B main camp.

"The sky is getting dark, let's head back first," Hamaguchi suggested after looking at the sky.

"Hmm, then let's head south. Back to the base," Ying said, then started walking toward the east.

"The main camp is actually to the west," Hamaguchi reminded him.

"Hahaha, actually I knew that all along; this was just a test for you guys." Following that, Ying started walking toward the north.

"I told you it's this way..." Hamaguchi grabbed the back of Ying's collar and dragged him toward the direction of the camp.

"Wait, Tetsuya, there's someone ahead!" Shibata called out to Hamaguchi, who was trying to rush back to the base, and pointed at a tree in front of them.

They saw a male student covered in injuries lying under the tree, and Ying walked up to him with trembling steps. He exclaimed:

"He's dead!"

"I am not!" the student said.

"A zombie!!!"
