With this magical mutation bead, Yu Kai finally woke up slowly.

"Master, Master, are you okay? Do you feel better?" Wu Xiaohu touched Yu Kai's forehead anxiously, his eyes full of anxiety and longing, as if he wanted to see through Yu Kai's condition at a glance.

"Xiao Kai, you must get better soon! It's all because of those nurses' ignorance that they made you so weak!" Academician Chao said angrily.

Yu Kai forced a weak, soft smile. He rolled his eyes and looked around. He saw several female nurses standing nearby, their eyes red and wiping away tears. Academician Fang was sternly reprimanding them. He immediately turned to Elder Chao beside him and said, "Elder Chao, it's none of their fault. I was the one who insisted on them smoking more. They always remind me."

"Xiao Kai, look, I got you some mutated prawns from the research institute. They are good stuff! The research institute said that they have just shed their shells and are a great tonic to replenish your body!" Old Chen hurried to Yu Kai's bed with a few prawns and said to him with hope.

"Mr. Chen, why do they need to shed their shells?" Yu Kai seemed to have thought of something and asked anxiously. A glimmer of hope flashed in his eyes for a moment. That light was like a spark in the darkness, weak but full of possibilities.

"The shrimp's shell is a hard exoskeleton that does not expand as the shrimp's body grows. When the shrimp's body grows, the original shell will restrict its growth, so it needs to shed the old shell so that the body can continue to grow. If the shrimp's shell is damaged, such as being attacked by other creatures or corroded by certain chemicals in the water, molting can allow the shrimp to get rid of the damaged shell and regrow a complete and healthy new shell, which helps them maintain good physical condition." Although Mr. Chen was confused by Yu Kai's sudden question, he still explained very patiently.

Yu Kai listened to Mr. Chen's explanation and kept thinking in his heart that although his physical condition was so bad, perhaps he could also, like the shrimp, find some way to get rid of the current predicament and gain a new life.

"Break out of the shell and be reborn! Can I also break out of the shell and be reborn, get rid of this weak physique, and make myself stronger!" Yu Kai looked at Xiaohu firmly and said, "Brother Xiaohu, you protect me. I want to shed my shell and be reborn like a shrimp." His eyes were full of determination, as if he had seen the dawn of success.

"Ah! Master, is this possible?" Wu Xiaohu frowned, his face full of worry, and said worriedly.

"Of course I can!" Yu Kai said firmly, leaving no room for doubt. He then looked at Elder Chao and the others, "Elder Chao, please help me contact Niuniu and ask her to come back soon. Tell her that I have a way to recover and ask her not to take any more risks. The mutant creatures out there are too powerful, and I'm really worried about her!"

"Xiao Kai, are you sure you can do it?" Mr. Chao asked with trembling hands and a worried look on his face.

"Don't worry, Xiaokai. We have made sufficient preparations and will start the counterattack tomorrow. We will definitely help her." Academician Fang said with a serious expression as he stepped forward.

"Okay, everyone, please help me take good care of her. I want to find a way to shed this body and rebuild a new life!" Yu Kai's eyes were as firm as steel, and that gaze seemed to be able to penetrate all obstacles and reach the other side of victory.

"Young Master, even if you have lost too much blood, you have already reached the level of a saint and should not be so weak! What is going on? You are not a shrimp, can this method really work?" Wu Xiaohu was restless, pacing back and forth beside the bed, and said worriedly.

"I'm afraid my body has been tampered with by the Book of Life and Death. If I can't get rid of it, it will be difficult to recover!" Yu Kai said with a solemn expression and great seriousness.

"Ah!" Wu Xiaohu also remembered what Zhong Kui said at that time, "Those who are injured by the Book of Life and Death will die. Their souls will be extracted by the Book of Life and Death!" His voice was full of fear and astonishment, and his body trembled involuntarily.

"This is why I have not been able to fully recover, so I must get rid of it, I must find a way to survive!" Yu Kai's tone was firm, with the courage to burn his boats.

"So, you've never recovered!" Old Chao looked at Yu Kai, whose face was as pale as paper, and couldn't stop crying. "Why are you so stupid?"

"Mr. Chao, I'm fine. You all should go out and don't let anyone disturb me. Take good care of my younger sister for me. I will definitely succeed. You all must believe in me!" Although Yu Kai's voice was weak, it was full of strength that made people unable to refuse.

"Ah!" Academician Fang sighed, wiped the tears from his eyes, and slowly walked out with Elder Chao. Soon, Wu Xiaohu was the only one left in the ward guarding his bedside, and the atmosphere was particularly heavy.

Streams of spiritual energy slowly enveloped Yu Kai, gradually forming a cocoon in the shape of a human. Yu Kai racked his brain, searching for a way to regenerate within himself. He had to find a way to regenerate, the only way to escape the strange Book of Life and Death. He closed his eyes tightly, his brow furrowed, his mind reeling through countless possibilities, like groping in the darkness for a lighted exit. He had no one to rely on at this moment, and could only constantly remind himself not to give up, to cling to even the slightest glimmer of hope.

Wu Xiaohu stood nervously beside the bed, staring at Yu Kai who was wrapped in spiritual power without blinking. His hands clenched into fists unconsciously, his palms full of sweat, and he silently prayed in his heart that Yu Kai would succeed.

Time slipped by, day after day. The light of the spiritual cocoon surrounding Yu Kai was initially intense, like a glittering star, then gradually dimmed, like a candle in the wind, until it was almost completely extinguished. Even Wu Xiaohu, carefully examining him with his spiritual power, could not detect any trace of his presence. Furious, he hurried forward, extending his hand to break the cocoon open. However, his outstretched hand froze in mid-air. "The young master must be fine. I can't disturb him. I absolutely can't." He hurriedly wiped away his falling tears and sat back down. "Hey, how could the young master be okay? I'm just overthinking!" His portly body trembled slightly, his worry undimmed.

Outside the ward, Elder Chao, Academician Fang, and others were also extremely worried. They came to visit again and again, but each time they were blocked by Wu Xiaohu, just to prevent them from entering and disturbing Yu Kai.

Elsewhere, on the edge of another cliff, Niuniu was locked in a thrilling battle with a mutant golden eagle king. She had held her ground there for a full month. For that entire month, she had kept a close eye on the nest of mutant golden eagles, striking decisively at the first opportunity. Each time, she was pursued frantically by the mutant eagles, but she always managed to escape. Returning again and again, in these life-or-death struggles, her strength and speed grew ever more swift. Lately, she had become unusually brave, as if a powerful conviction sustained her. She sensed something significant was about to happen, becoming extremely frantic and her fighting power dramatically increased. She had taken on the mutant golden eagles returning from their foraging trips, one after another, with surprise attacks and slayings. Today, she faced the mutant golden eagle king, returning from their foraging trips. The two engaged in a fierce clash, with the wind and clouds shifting and sand and rocks swirling. In the end, Niu Niu burst out with all her strength, struck hard, and successfully killed the mutant golden eagle king.

She carefully took out the huge mutation bead, and a happy smile spread across her face, like a flower blooming in spring. "Brother, I have collected 52 mutation beads. Now you will definitely be able to recover!"
