Through repeated combat drills, everyone constantly summarized their experiences and refined their tactics. Crises that once required immense effort to address were now easily resolved. The base's defenses were also comprehensively strengthened, enhanced by everyone's special abilities. Both physical defenses and energy shields proved incredibly effective, deterring the enemy.
Furthermore, the survivors' mental fortitude has grown immensely through constant training. Faced with unknown dangers and powerful enemies, they no longer shrink from fear or retreat, but instead embrace the challenge with confidence. This growth in spiritual strength has imbued the entire base with a spirit of courage and fearlessness.
Through the joint efforts of Xiao Yi and the survivors, the base has gradually transformed from a fragile shelter into an indestructible battle fortress, standing firm in the storm of the end of the world, guarding everyone's hope and future.
In addition to the busy training, Xiao Yi always kept the research on the zombie crystal core in his mind. Every free moment, he would plunge into the specially set up research room.
The table in the laboratory was filled with various tools and instruments, including microscopes, chemical reagent bottles, dissecting knives, etc., in a messy yet orderly manner. Xiao Yi wore thick goggles and held a crystal core that had just been taken out of a zombie's skull in his hand, observing it carefully.
He first examined the surface texture of the crystal nucleus with a magnifying glass, not missing any tiny wrinkles or spots. Then, he placed the nucleus under a microscope, adjusted the focus, and stared intently at the eyepiece, trying to uncover the hidden secrets.
Xiao Yi would carefully cut a small part of the crystal nucleus with a knife, place it in the reagent, and observe the chemical reaction. Sometimes the reagent would bubble violently, and sometimes it would change color and precipitate. He recorded each reaction in detail in his notebook.
In order to gain a deeper understanding of the internal structure of the crystal core, Xiao Yi also uses special scanning equipment to generate a three-dimensional image of the crystal core. He constantly analyzes and thinks about the intricate images on the computer screen.
He would also read through a large number of books and materials, searching for any information that might be related to the zombie core. Even a single word would make him excited, as if he had found a ray of light in the darkness.
During his research, Xiao Yi encountered countless difficulties and puzzles. However, he never gave up. Instead, he became more determined to uncover the mystery of the crystal core. He often worked in the laboratory late at night, forgetting the passage of time.
Sometimes, to verify a hypothesis, Xiao Yi would conduct repeated experiments, constantly adjusting his methods and procedures. Even if he failed again and again, he remained convinced that with perseverance, he would eventually find the key to the zombie crystal core. ...
Xiao Yi was like a man possessed, devoting himself wholeheartedly to the research of zombie core extraction technology. During the day, after leading everyone in training on the training ground, he hurried back to the laboratory, not even bothering to wipe the sweat from his forehead, and immediately started a new round of attempts.
His desk was piled high with thick documents, and the walls were covered with his own sketches and data records. Xiao Yi often sat for hours under the dim light, his eyes fixed on the crystal core and experimental equipment in his hands, not missing any subtle changes.
Initially, he used simple physical methods to extract the crystal core, carefully removing it from the zombie's skull with tools. However, this method was not only inefficient but also easily damaged the crystal core. Therefore, Xiao Yi began to try chemical methods, mixing various reagents, trying to find a solution that could dissolve the surrounding tissue without damaging the crystal core.
The repeated failures of the experiment made Xiao Yi feel extremely frustrated, but he never thought of giving up. He constantly adjusted the ratio of reagents and changed the conditions of the experiment. Every failure became a valuable experience for him to improve his technology.
In order to improve the purity of the extraction, Xiao Yi also modified the experimental equipment himself. He searched for usable parts in the waste materials and assembled them into new extraction devices. Sometimes, for a key component, he would run all over the base and seek help from other survivors.
In countless sleepless nights, Xiao Yi repeatedly thought about every step of the experiment, wondering how to break through the existing bottleneck. His brain was always running at high speed, thinking about new ideas and methods.
After a long period of hard work, Xiao Yi finally made some progress. He discovered a new extraction method that could greatly improve the efficiency and purity of the extraction while ensuring the integrity of the crystal core. However, he was not satisfied with this and continued to improve and perfect this technology, striving for perfection.
In this process, Xiao Yi invested time and energy that ordinary people could hardly imagine. His persistence and perseverance allowed him to go further and further on the research path of zombie crystal core extraction technology.
During those long years of research, Xiao Yi experienced countless failures and setbacks. Every unsatisfactory experiment was like a heavy hammer hitting his heart.
Countless times, he had begun extraction operations with great anticipation, only to discover at the last minute that the crystal core had been damaged, or that the purity of the extracted material fell far short of expectations. Those failed scenes resurfaced repeatedly in his mind, becoming a lingering shadow.
Once, he carefully prepared the reagents according to a newly conceived method and began the experiment with confidence. However, during the critical step, the reagents reacted violently, not only blowing up the experimental equipment but also nearly injuring him. At that moment, Xiao Yi looked at the messy laboratory, his heart filled with loss and self-doubt.
Another time, he worked tirelessly for days and nights to improve the extraction device, but when he put it into actual operation, the device frequently malfunctioned, forcing the entire experiment to be interrupted. Xiao Yi sat exhausted on the ground, his eyes revealing deep helplessness and despair.
