"No, no, it definitely won't happen!" Yu Kai looked anxious, his voice almost hoarse, and he shouted madly, "There is a way, there must be a way!" His eyes were bloodshot, and he seemed to have fallen into an endless dark abyss, tightly wrapped in endless panic and despair.

At that moment, a large army surged forward like a tide, their steady, heavy footsteps shaking the ground slightly. Then, a group emerged, led by Commander No. 1, Commander No. 2, along with Elder Chao, Elder Fang, and the others. Commander No. 1's expression was as solemn as steel, his steps firm and powerful. He pushed aside those who tried to stop him, and slowly stepped forward, holding a delicate box steady in his hand. As Yu Kai watched him approach, a fierce gleam flashed across his face, a terrifying murderous intent emanating from him, the air around him seemingly thick with this intense killing intent.

"Yu Kai, calm down. We have all been deceived by Tian Lin. He is so bold that he imprisoned two leaders! All the orders were given by him on his own. Don't worry, the leaders have sent people to hunt him down!" Academician Chao Tian was extremely anxious. He took two steps at a time and quickly stepped forward. He stood next to Leader No. 1 and explained at a very fast speed.

"Xiao Kai, this is the mutant bead that our Longguo collected with great difficulty. Tian Lin has always wanted it. Now I am handing it over to you. I hope it will be useful to you!" Leader No. 1 walked forward, his voice low and sincere, slowly opened the box, and solemnly placed it in front of Yu Kai.

"Mutation beads! Mutation beads!" Yu Kai seemed to have grasped the last straw, reaching out to grab the mutation beads, desperately feeding them to Niu Niu. However, at this moment, Niu Niu slowly closed her eyes, her hand slid to the ground, and she could not swallow the mutation beads in her mouth.

"No! No! Niuniu, little sister!" Yu Kai panicked, his voice trembling. "Can't you swallow it? I'll refine it for you!" He grabbed the mutation beads with trembling hands and mobilized his spiritual power to refine them frantically. Each mutation bead transformed into a dazzling beam of light, which he forced into Niuniu's body, but Niuniu remained unchanged.

"How could this happen? How could this happen?" He was like a frantic beast, in a state of panic, roaring at the top of his lungs. The sound pierced the sky, filled with endless pain and despair.

Elder Chao quickly secured the No. 1 officer behind him, his expression utterly nervous, fearing he might be accidentally injured by the irrational Yu Kai. The other officers quickly gathered around to provide support, forming an impenetrable protective circle not far away.

"Niuniu, I don't want you to die, I don't want you to die, wake up now, wake up now!" Yu Kai touched Niuniu's bloodless face, tears streaming down his face like a flood. His voice was shrill and heartbreaking. He looked so helpless, so pitiful, as if the whole world had completely collapsed at this moment, plunging into endless darkness.

"Boom!" A loud thunderclap exploded, and the sky seemed to be torn apart. Heavy rain began to fall, like a river pouring down from the sky. The bean-sized raindrops mercilessly pounded on Yu Kai and Niuniu, as if they were also weeping for their tragic experience. Yu Kai looked up at the gray sky and shouted at the top of his lungs: "God, why did you do this to her? She has suffered enough, why don't you let her go!"

"Mom! Mom! Mom, where are you? Please save Niuniu, please save her!" Yu Kai screamed in the rain, his voice filled with pleading and unwillingness. The cold rain drenched him and Niuniu, but there was still no response. Only Yu Kai's desperate cries echoed in the rain.

He recalled what his mother had once said, "No matter how poorly my son's test scores turn out, he doesn't steal or rob, and has never harmed others or society. He knows how to be filial to his parents and has a sense of propriety, righteousness, and honor. He possesses a kind character, respects others, and is compassionate. He stands up to injustice and has compassion for the weak. He is positive and optimistic in life and never gives up easily in the face of difficulties."

"Never give up easily, right! I can't give up like this, I have to find a way, calm down, I have to stay calm, there must be a way!" Yu Kai tried his best to calm himself, but his hands kept shaking uncontrollably, "There is a way, there are always more solutions than problems, I just haven't thought of it yet!"

Suddenly, his eyes lit up. "Yes, there must not be enough mutation beads. They are too weak. I need to find more! Yes, that's it, that's definitely it!" Without hesitation, he picked up Niuniu. His mechanical wings instantly unfolded, their powerful force causing the air around them to tremble. He soared into the sky like a flash of lightning, darting through the rain at astonishing speed.

He soon arrived above Xiangnan, looking down. He saw countless mutant creatures frantically devouring and evolving, emitting a terrifying aura. Yu Kai's eyes shone with bloodthirsty light, and he looked at Niuniu in his arms with loving care. "Little sister, these will all be your healing elixir. You will be well again soon!"

"Roar!" The mutants on the ground also noticed Yu Kai in the air and let out earth-shaking roars. They leaped between the tall buildings one after another, rushing towards Yu Kai like cannonballs.

Yu Kai's expression was impassive. A powerful spiritual force instantly and gently enveloped Niu Niu, causing her entire body to slowly float upward. Undaunted, Yu Kai swooped down directly towards the mutant creatures, his sword wielding like a dragon emerging from the sea, dancing with abandon. One giant mutant beast after another was instantly slain by his sword, and he precisely delivered powerful mutation beads to Niu Niu's side. Niu Niu's entire body was soon engulfed in layers of these beads.

Mutated creatures surged around him like a tide, but Yu Kai descended like a god of death. "Kill!" he roared, his spiritual energy surging like a volcanic eruption. He swung his mechanical sword, slashing at the surroundings. Each swing unleashed a massive sword beam, and wherever it passed, it was like a nuclear explosion, a powerful wave of energy spreading rapidly and devastatingly. All of Xiangnan was enveloped by his devastating sword light.

Countless mutant creatures were instantly devoured by this terrifying energy wave, their bodies exploding as mutant beads rained down. Buildings collapsed under the impact, bridges broke, the earth trembled violently, and rivers flowed backwards, creating a scene of doom. The mutant forbidden zone, which had terrified the entire world, was reduced to ashes in the blink of an eye. Satellite footage showed nations around the world witnessing this scene, trembling with fear and marveling at Yu Kai's terrifying power.

Yu Kai watched all this with indifference. He raised his mechanical arm, and the mutant beads in the energy wave quickly gathered towards him as if summoned. He refined each of these mutant beads with even more violent spiritual power, continuously injecting them into Niu Niu's body. Niu Niu's entire body was tightly wrapped by this extremely powerful force.
