Chapter 37: The raw materials needed for the operation, everyone should find them by themselves
Teacher Chen Feng stood tall in front of the laboratory table. The bright light in the laboratory shone on him, outlining his focused and serious profile. His eyes were like torches, slowly scanning the pairs of curious and expectant eyes below the stage, clearing his throat and saying, "Students, today we are going to learn some important chemical reagent debugging methods, which are crucial for us to handle various materials."
He turned gracefully and picked up a transparent container, which contained a stone emitting a strange luster. The surface of the stone seemed to be flowing with a faint halo, attracting everyone's attention. "First, let's take a look at this stone, it's called 'glow stone'." Teacher Chen Feng's voice was steady and powerful, "Glow stone contains a special substance, and after a specific chemical treatment, we can extract the ingredients we need."
Teacher Chen Feng put on protective gloves that fit his fingers like a second skin. He picked up a small and delicate hammer and tapped the stone gently. "Everyone, please note that when breaking the stone, the force should be moderate to avoid damaging the internal structure." His movements were gentle and precise, and each strike was just the right amount of force. As the stone was gradually broken, tiny fragments scattered like stars. Teacher Chen Feng skillfully screened and separated, his fingers dancing flexibly to extract some fine powder from it. The powder flashed a mysterious light under the light, as if it contained endless mysteries.
Then, he picked up a green plant. The leaves of the plant had clear vein-like textures, and each texture seemed to tell its unique story. "This is 'Spiritual Pattern Grass'. From its stems and leaves, we can extract a juice that can enhance the stability of reagents." Teacher Chen Feng used a special sharp tool to carefully cut the stems and leaves. The tool seemed to have become an art tool in his hands, and each cut was just right. The green juice slowly flowed out, as crystal clear as morning dew. Teacher Chen Feng carefully collected the flowing juice into another clean container.
"Also, extracting materials from the corpses of star beasts is also a common method." Teacher Chen Feng placed the corpse of a small star beast steadily on the operating table. Even though the star beast had lost its life, its body still exuded a majestic aura. "For example, this 'Fast Shadow Beast' has a precious liquid stored in its gallbladder. It is highly corrosive, but after neutralization, it can become a key component in our reagents." Teacher Chen Feng's eyes became more focused. He carefully dissected the corpse of the star beast, and every movement was full of awe and caution. He took out the gallbladder, which trembled slightly under the light, as if it still retained the power of the star beast when it was alive. Teacher Chen Feng carefully handled the liquid in it, not letting a drop go to waste.
"Look, extracting these materials is only the first step. Next, we need to make precise proportions and reactions." Teacher Chen Feng mixed the collected materials in a certain proportion. His eyes were focused and determined, as if he was performing a sacred ritual. He added other chemical reagents and then stirred slowly and evenly with a glass rod. The liquid swirled and merged in the container, emitting a strange smell. Then, he placed the container on a heating table, adjusted the temperature, and carefully observed the changes in the liquid.
Throughout the entire process, Teacher Chen Feng constantly emphasized the key points and precautions of the operation. His voice echoed in the laboratory, like an alarm bell knocking at the hearts of every student.
Su Nian sat in the audience, staring at every move of Teacher Chen Feng without blinking, and quickly recorded in her notebook with a pen in her hand. Her eyes were full of concentration and desire, and she was afraid of missing any details. Her notes were densely packed, and her handwriting was neat. Every word carried her persistent pursuit of knowledge.
After Mr. Chen Feng finished a stage, he looked at the students and said, "Now I'll ask a question. Who can tell me what we need to pay attention to when extracting materials from glowstone?"
The students lowered their heads, fearing that they would be called out. Su Nian took a deep breath and raised his hand.
Teacher Chen Feng showed a gratified smile on his face and said, "Su Nian, you answer it."
Su Nian stood up and said in a clear voice: "When extracting materials from the glowstone, be careful to strike with moderate force to avoid damaging the internal structure and affecting the purity of the extracted ingredients."
Teacher Chen Feng nodded with satisfaction: "Very good answer, please sit down. Who can tell me the key steps of extracting the juice of Lingwen grass?"
Another student was called on to answer, and the classroom atmosphere was tense and active.
……
Teacher Chen Feng ended the question-and-answer session and said with a serious expression, "Next, I'll assign you this assignment. Xingyao Mountain, southwest of the school, has the raw materials we need for this assignment. Everyone can go and look for them on your own."
When the classmates heard this, they couldn't help but talk about it in a low voice.
Su Nian turned on the optical computer to check the map and couldn't help but gasp. She realized that this school was so big. This school alone was as big as a province on Earth! And this first planet was even more vast, millions of times larger than Earth!
Teacher Chen Feng continued, "This assignment requires you to find various materials from Xingyao Mountain and synthesize ten chemical reagents. You should review the knowledge you have learned before and check the information more, so as not to forget the raw materials and not know what they are when you walk by. Of course, these words are mainly for the novice students."
"There are some small mutant animals, some mutant plants and some irradiated plants on Xingyao Mountain. In addition, there are some precious minerals and strange stones. You can form a team to search together, or you can act alone, but when you encounter danger, you must press the call button in time, and the school's rescue personnel will arrive as soon as possible." Teacher Chen Feng emphasized safety matters.
"I hope everyone can complete this assignment successfully. Okay, get out of class is dismissed!" Teacher Chen Feng said, and then left the laboratory.
Su Nian packed her things and began to think whether to go alone or find a partner to form a team. She walked and thought, and unknowingly walked to the square of the campus. At this time, the students gathered in groups of three or five to discuss the homework. Some had already formed a team and were excitedly planning the itinerary; others, like Su Nian, were still hesitant.
Su Nian looked up at the sky and secretly encouraged himself in his heart: No matter what, I must complete this assignment and improve my abilities.
