Learn about the human body

Fu Yansheng applied for them to be in the laboratory at noon on Thursday.Before, he was a sophomore doing experiments. He first helped the administrator clean up the laboratory, and then sorted and checked the equipment.

"Students from their design department will come in a while, and you ask them to sign off the safety commitment book. Be sure to keep an eye on me. There was such a big accident in the laboratory the year before last. For safety reasons, theoretically we don't want to disclose it casually." Open to college students." The administrator explained to him seriously, the meaning behind the words was self-evident.

Fu Yansheng nodded: "Don't worry, I will be optimistic about them."

The teacher was still expressionless and wanted to say something, but there were noisy conversations on the stairs.Knowing that the teacher doesn't like making noise, Fu Yansheng glanced at the door and said first, "I'll tell them to be quiet."

Because the laboratory is relatively small and involves safety issues, Fu Yansheng only allowed a few core members of their group to come.When I walked out, four or five people were carrying the tripod and dragging the reflector upstairs.

"No noise is allowed in the laboratory." He walked up to remind him coldly.The corridor was quiet for a moment, Tang Qizhen ran a few steps to him, and said sorry several times.

After the five people walked into the laboratory, the administrator repeatedly emphasized the precautions and asked them to sign the commitment book.Before leaving, he did not forget to tell Fu Yansheng "no accident".

The exterior walls of the laboratory building are old, but the tables and chairs inside look brand new.Qiu Jingya set up her camera behind the test bench and looked around curiously.

"That woman, don't look around." Fu Yansheng took out a few bottles of reagents from the cabinet and put them on the table, "I'm just going to show you the simplest experiment, and I'll leave after the filming."

After speaking, he took out the gloves from his pocket, flipped them over carefully, completely wrapped the wrist and cuffs inside, and then took out the protective glasses and put them on.

"Is this goggles?" Gu Xuehao looked at the novelty and couldn't help talking, "It's so formal, it's like making biological and chemical weapons."

"If you talk too much, get the hell out." Fu Yansheng raised his head and swept his eyes, even through a layer of plastic lenses, it was still piercing.He tapped the table again with his knuckles, and said in a low voice, "Do you know why these devices are new? Because there was an accident here, and the three corpses of my classmates were released on the stairs you just came up."

"Really?" Gu Xuehao suddenly turned pale with shock, glanced at the bright sunshine outside the window, but his back was shivering with cold.Tang Qizhen remembered that the senior had mentioned this matter, so he quickly pulled him aside, and warned in a low voice: "Stop talking nonsense, start quickly."

After finishing speaking, he looked at the reflector in Gao Tongfang's hand and asked, "Is the light adjusted?"

The laboratory is shaded and the lighting is average, so tools must be used.Gao Tongfang and Qiu Jingya, who was in charge of photography, made gestures and said firmly, "It's all right."

Only then did Tang Qizhen retreat to the side in peace of mind, Qiu Jingya fiddled with the camera, and said again: "Brother Zhen, you can stand over the cabinet, it's a bit blocking the camera here."

"Okay." He just nodded, and before he finished speaking, Fu Yansheng turned his head and looked at him, warning: "Don't lean on the reagent cabinet."

"Don't worry, I won't cause you any trouble." He shrank obediently in the corner.

The beater fell, and Fu Yansheng started to move cooperatively.What he demonstrated was the simplest biuret reagent configuration and protein detection experiment. The reason for choosing this is firstly for safety reasons, and secondly, copper sulfate solution will be used in the experiment.This is a blue solution, Fu Yansheng thought, if they use colored reagents, the pictures they take should be more vivid and photogenic.

He did this experiment several times when he was a sophomore, and he calculated the measurement before configuring. Now the operation is smooth and smooth, weighing, stirring to dissolve, and constant volume are all done in one go.Tang Qizhen looked at his slightly drooping side face from the side, as if he could pour all the seriousness and care in his eyes into the beaker.He stared at it for a few seconds, and couldn't help but be attracted by the natural charm of the other party, for a few seconds he forgot to breathe.

As the reagent dripped into the test tube, Fu Yansheng held it up to eye level, flicked his wrist a few times, and the purple slowly spread like a ribbon.

"The demonstration is over." Fu Yansheng glanced at it again and put it on the test tube rack. "You can go back."

"Wait a minute, let me watch the replay to make sure." Qiu Jingya bent down in front of the camera, "Brother Zhen, I think the senior is quite tired from taking pictures, you can help him clean up together."

"No need." Fu Yansheng stopped him without raising his head.

This experiment lasted for 10 minutes, but the clips that were actually cut into the microfilm were only tens of seconds.Tang Qizhen saw that his forehead was a little sweaty, and wanted to go forward and give him a piece of paper.He lowered his head and felt in his pocket while taking a few steps forward.

Suddenly, a dazzling light flashed in front of his eyes, as if the shadow of a sharp-edged sword was directly slashing at him.Tang Qizhen wanted to dodge subconsciously, and the tissue in his hand fell to the ground.In a trance, there was another white light in front of him. In the darkness, he lost the most basic judgment, shouted in a panic, and his body fell to one side uncontrollably.

"Ah——"/"Danger!" Someone's voice sounded in the darkness, and the thing that fell into meat paste did not happen.Immediately there was a violent collision, and with the sound of the iron sheet vibrating, the person next to the ear gasped.

Fu Yansheng flew over at almost the speed of light and grabbed his shoulders, shielding him against his chest in the blink of an eye, and willingly bumped into the reagent cabinet that was one person tall behind him.

The left shoulder hit the cold edge directly, half of the glass shattered, and split into honeycomb-shaped obtuse-angled particles from the point of force.

Tang Qi huddled in his arms, still panting heavily in shock.Trapped by the panic and pain for a moment, Fu Yansheng bit his lip hard before recovering. He glanced sideways at the horrible scene in the cabinet, raised his hand and grabbed Xiao Tang by the collar: "Tang Qizhen, you are a fucking pig!" !?"

"..." The rest gasped, and the audience fell silent.

"I'm sorry, it's my fault..." There was still some inexplicable halo in front of him, rubbing his eyes uncomfortably, and he was so frightened that he burst into tears.

"Cry, cry, cry! How do you know how to cry!" Fu Yansheng yelled and took him aside to stabilize him, then immediately turned around and took out the key from his pocket to open the door of the reagent cabinet.

One of the reagent bottles has been knocked over, and a pile of crystal fragments and search liquid has been spilled.Fu Yansheng also panicked for a moment, raised his hand to cover his mouth and nose, and carefully turned over the broken glass with tweezers to check the label.Fortunately, it was sodium carbonate, he was slightly relieved, and turned to look at Tang Qizhen.

He rushed up to pick him up, and then cast a fierce glance at everyone present: "What's going on?"

"A light flashed in my eyes..." Tang Qizhen shrank into a ball in fright.

"Light?" Fu Yansheng raised his eyebrows and glanced out of the window, his eyes locked on Gao Tongfang, "The one over there, do you know what's going on?"

"I'm sorry," Gao Tongfang quickly apologized, "Senior, I'm sorry, but, maybe I didn't pay attention when I closed the reflector, and it flashed to..."

"Enough," Fu Yansheng stopped him, "You all follow me to see the teacher."

After finishing speaking, he brought Xiao Tang closer to him, and scolded: "I have never seen a person as stupid as you in my life! Didn't I tell you, isn't someone coming every time?" Take care of you!"
