Unlimited Copies of Onizuka Class

One day before morning class, something that did not belong to them appeared in the dormitory of every student in Onizuka class. Some people received pistols, some received unknown potions, some received walkie-talkies, some received flashlights... Some even received dozens of 3D printers, leaving the room with nowhere to stay. Out of caution, everyone took the items they received and came to the classroom. The classmate who received the printer was so pitiful that he called his friends to help move it several times. Instructor Onizuka stood on the podium with a gloomy expression. Everyone saw that on the podium in front of him was a bottle of dark red human blood and a card. The label on the bottle is full of weirdness: the blood of one of the Onizuka class students has an exorcism effect and can be used for DNA testing. There are words printed on the card in red letters on a black background that cannot be read clearly. After explaining the situation, Onizuka asked the students entering the class to hand in all the items they received in front of the classroom. The prank here has been reported and a professional team has been involved in the investigation. Because the surveillance cameras were hacked, no one knew what was going on in the dormitory building. When the five-person group arrived at the class, they noticed that the atmosphere was a little strange. Without asking, instructor Onitsuka asked them to put the items in the dormitory on the podium. "What item?" The five people looked at each other. "You guys, didn't you receive it?" A timid student who arrived early for class asked cautiously. "Did you receive that pile of strange things on the podium?" Matsuda Jinpei asked. The students nodded quickly. "No?" The five people sat down in their seats one after another, and Datehang scratched his head. The classmates behind Rei Furitani's seat all showed horrified expressions and blinked wildly at instructor Onizuka, but Onizuka, who was focused on the bottle of blood in his hand, didn't see it. Hagiwara Kenji showed a curious expression, "What happened? Did you deliberately not take us to play?" Onizuka ignored Hagiwara's words with the purpose of enlivening the atmosphere and named his favorite chief, "Fukitani." Jiangu Ling was full of energy: "Yes!" "Have you encountered anything recently?" "Not really!" Instructor Onizuka picked up the bottle of dark red liquid: "Okay, but the test report the hospital gave me said that this is your blood." "What?!" Zhu Fu Jingguang jumped up from his seat, teleported to Jiangu Ling's side and started checking without any explanation. Since it was still early for class, Onizuka didn't say anything, but just asked again: "Are there any wounds on his body?" Zhu Fu Jingguang didn't say anything. He stared at the writing on Jianggu Ling's neck under his blond hair without blinking, and read out: "No, do you want to turn back?" He was the first to react, and he pressed Jiang Gu Zero's conditioned reflex to look at his head: "Zero, don't move!" Jinpei Matsuda, who was closest to Rei Fukutani's seat, also stood up and looked at the back of Rei Fukutani's head: the handwriting seemed to have been scratched with a sharp knife, and the blood flowed out a step slower and stained his back. The school uniform was soon covered in blood red. Fangtani Rei's expression was innocent and at a loss. He stiffened his neck and shouted softly, "Ah, it hurts, it hurts, it hurts, it hurts." Instructor Onizuka took three steps at a time and came over to check the injury with a serious expression. Just in time to see the last word written, the wound healed quickly, leaving only the scar: Don't look back, death is behind you. ***** There are 30 students and 1 instructor in the private class. Everyone except the five-person group received physical objects. Intention: The whole class will enter unlimited dungeons!
