Chapter 19 Accident

On the second day of the Technology Open Day, it was business as usual.

The laboratory in the afternoon was as quiet as a stretched white paper.The air conditioner with constant temperature and humidity was running quietly in the ceiling. The white light illuminated the stainless steel countertop coldly. The temperature control screen of the tube furnace flashed with tiny digital light spots and beat steadily.Behind the glass door, the corridor is empty. Occasionally, footsteps pass by in the distance, and the echo is light and empty.

Lin Yi only arranged routine inspections today.The undergraduate class in the morning had just ended, and before he had time to eat, he shook the coffee cup in his hand and looked at the instruments in several rooms before stopping in the laboratory closest to the ventilation shaft.Several graduate students are gathering next to the tablet press, taking turns loading the sulfide electrolyte powder that was dried the day before into the mold.There were three pieces of paper in the oven marked “72h/48h/24h”. The top one was hurriedly torn off, and the corner of the paper was still curled up.

The air was so dry that it felt slightly itchy in the sense of smell.The smell of sulfur is like a very thin line, stretched between the nose and throat, vaguely present.Lin Yi wore goggles, rolled up his sleeves to the outer pockets of his lab coat, folded his arms in front of his chest, looked at his watch, and then at the hygrometer next to the tablet press, and casually reminded: “Move quickly, don’t stay in the air for too long. After weighing, seal it, and lower the fume hood door a little.”

“Okay, teacher.” The student closest to him responded, turned sideways to reach for the mold, and accidentally knocked down the tweezers in his hand. The metal jingled slightly, and he hurriedly held it back.

Lin Yi had no intention of doing it himself.He just observed whether the process was consistent with last week’s review: weighing, transfer, pressing, packaging, and the record sheet for each step was sandwiched in the plastic board.He lowered his head and turned a page, and clicked the pen tip on the “Exposure Time” column. Just as he was about to speak, there was a very faint sound of metal friction in the furnace, like someone rubbing a fingernail behind the glass, and then everything calmed down again.

“Move more neatly.” He raised his head, his voice was not high, but it was filled with indisputable affirmation.

Just then, an accident happened.The mold mouth suddenly let out a muffled “pop”.The white powder exploded instantly like a torn yarn, and the sparks shattered into tiny pieces and surged outward with high-temperature air currents.Almost at the same moment, white smoke poured out from the gap between the mold and the air. First it was a wisp, and then it formed a ball, as if someone had opened a bottle of dye in transparent water and spread quickly around.

The smell of rotten eggs instantly pierced everyone’s sense of smell.The red light of the alarm probe flashed suddenly, then flashed steadily, and a harsh buzzer came from the ceiling.

“Back off!” Lin Yi didn’t think twice.His body completed the action before he realized it: he took a step forward and his hands were already pushing the student closest to the stove.At that moment, sparks hit his sleeve – the outer layer of the cotton cloth first bulged out with a bright spot, and then quickly scorched black with a “sizzling” sound. The heat penetrated straight into the skin from the cloth layer like a hot needle.The pain was clean and sharp, almost nauseating.He subconsciously retracted his arm, but forcefully completed the push, and the student staggered back outside the fume hood.

The white smoke glowed turbidly under the lamp. Just as Lin Yi was about to speak, his throat seemed to be grasped by an invisible hand.The breath he took in amplified the sulfur smell into a burning sensation. The hot gas scraped through his trachea, and his chest immediately tightened.He wanted to shout “cut the power”, but his voice broke into a hoarse strand from the bottom of his throat: “…cut the power, turn on the fans!”

“Turn off the power! Cut off the power!” The student repeated his words and hurriedly pressed the main switch.Another person raised his hand to pat the air door of the fume hood. The transparent baffle slowly lowered, and the white smoke was dragged out into a spiral.The sound of the alarm hit everyone’s eardrums like nails.The pain in Lin Yi’s chest became tighter and tighter, and a fine mist formed on his goggles.He could clearly feel the edges of the burn bubbling rapidly, as if there was an invisible ring of fire slowly pushing out under the skin.He raised his eyes and scanned everyone’s standing position, making sure that everyone was outside the yellow markings, and then coughed lowly. The sound was like turning out the lungs, and the top of the sternum was scratched roughly, and his eyesight turned black for a while.

“Teacher -” someone called him, his voice already trembling with tears.

When the security guard rushed in, the light at the door was cut into sections of red by the warning lights.The intercom crackled in front of his chest, and he opened the inner door as quickly as possible. “Everyone retreat to the corridor! Don’t block the door!” He made a push-out gesture.

Teachers and students Lin Yi staggered out of the room and collapsed on the ground one by one.Not long after, the ambulance arrived, and the ambulance crew came in quickly carrying a stretcher. There was still a pungent smell in the air.Lin Yi still instinctively turned his head on the stretcher, trying to confirm the students’ condition.No one could give a complete answer, some nodded, some had red eyes, and some were so weak that they sat down against the wall.

When the stretcher was lifted, Lin Yi wanted to say something to the students, but he only squeezed out a heavier cough from his throat. His eyelids seemed to be pressed from the inside, and his vision seemed to flicker on and off, and finally darkened slightly.

At the same time, thousands of kilometers away, a flight from Florence was traveling smoothly high in the sky.

Gao Huan leaned on the seat and closed his eyes slightly. He did not fall asleep, but just let his body enter a slight floating state.There was music in the headphones, but his mind refused to stop.Xiao Zuo’s words echoed repeatedly in his ears – “The most important thing is to confirm whether the other person is the same person as you.” He once again recalled in detail every moment with Lin Yi: the casual glances, the deliberate sense of propriety, and the few moments when he seemed close to responding but quickly pulled away.

He thought, if he really wanted to continue, should he ask openly, or should he still test it secretly?

He had no idea that Lin Yi had been transferred from the emergency room to the inpatient unit at that time, with his arm wrapped in thick gauze and an oxygen tube attached to the side of his face.A few lines of words on the ward record board were calm and distant: second-degree burns, inhalation irritation, hospitalization for observation.

Cabin time is slow and steady.Airplane mode isolates all information from the clouds, which is like a rare health cabin in this era of information explosion.It was dark outside the window, and the wings of the aircraft drew a stable line in the silent air.

When the plane lands and the phone lights up again, dozens of unread messages will flood into the screen at the same time, like a sudden wave, completely hitting Gao Huan.
