两人隔空对战，强大的力量不断冲击碰撞，每一次交锋都使得道蕴虚秘境剧烈摇晃，仿佛随时都会崩塌。

而炎火云此时却难以插手，只能借助此地的混沌之水快速恢复自身实力。他心中暗自思忖：“这妙法师兄虽已化魔，但尚存一丝良知，否则以他的本事，又怎会与我缠斗这么久？想必他是在顾及同门情谊，如此看来，他还有救赎的可能。”

"Boom!" Another violent collision erupted. The force was like a bomb, shattering the surrounding void and sending the earth roiling violently like boiling water. Ripples radiated rapidly from the collision point. At that moment, a ghostly figure darted out from the depths of the earth, nimbly dodging the raging energy.

As Yu Kai retreated, he spotted the approaching figure: it was none other than Hou Tu Ling Ji. It turned out she had been hiding deep underground, cultivating. He had barely regained his balance in mid-air when Niuniu flew towards him like a streak of black light. Already startled by the aftermath of the fight between Yu Kai and the others, she now saw the imposing Master Miao Fa charging at her again. Her expression instantly turned cold, and with a whoosh, she charged forward like an arrow from a bow.

Just as Yu Kai was about to follow, he saw Hou Tu Lingji and Yan Huoyun flying over together.

They watched as Niu Niu attacked vigorously, and Master Miao Fa was defeated step by step under her attack. Even when he used the Buddhist treasure, the Posha Lingzhu, he was still unable to withstand Niu Niu's fierce offensive, and was beaten all over.

"Who is this? How can he be so powerful?" Yan Huoyun couldn't help but ask first.

"My younger sister, Lin Niuniu." Yu Kai replied.

"It's actually the Saint of the Dark Abyss Demon Alliance, Lin Niuniu!" Yan Huoyun and Hou Tu Lingji were both shocked.

"The Saint Girl personally trained by the three Demon Lords is indeed terrifyingly powerful!" Yan Huoyun sighed in his heart. The intensity of their battle has long surpassed the realm of the Great Lord. Even a peak Great Lord would probably be easily killed in front of them.

"Boom!" With a resounding roar, the body of the Miaofa Master exploded in the air, disintegrating into countless fragments. Lin Niuniu stood proudly in the void, her robes fluttering like a banished immortal, emanating an otherworldly aura. She turned gently and walked lightly to Yu Kai's side, her eyes filled with concern and inquiry.

Yan Huoyun and Hou Tu Lingji witnessed such a powerful Lin Niuniu, and couldn't help but worry about the Heavenly Court.

They knew very well that if there was no saint to suppress her and she was allowed to grow up, the Dark Abyss Demon League would probably give birth to another terrifyingly powerful Demon Lord.

"Brother! Where is Zhang Qiming?" Lin Niuniu saw Yu Kai smiling at her, and that smile was full of happiness for her, so she started to ask about Zhang Qiming's whereabouts.

"He ran away. This guy also got a ray of Hongmeng purple energy. It will be very difficult to deal with him if we meet him again next time." Yu Kai was still angry when he thought of this.

"What? There's actually a primordial purple aura in here?" Hou Tu Lingji exclaimed in shock, her face filled with disbelief. Yan Huoyun was also so shocked that he was speechless for a long time.

Even Nezha, who was concentrating on refining the Chaos Pearl, was startled upon hearing this and stopped what he was doing. He pondered to himself, "Master left behind the Primordial Purple Qi, why didn't he pass it on to me? Why doesn't it recognize me? Even the Purple Sky Spirit Pearl refused to leave with me. Could it be that in Master's eyes, I am so unbearable?"

"Brother, the aura of chaos here is extremely strong. He must still be hiding in this secret realm. Go and practice quickly. I'll guard the exit and see how he escapes."

After Lin Niuniu glanced around, she stared at Yu Kai and spoke seriously.

"How can that be? You go and practice, and I'll look after you." Yu Kai naturally didn't want his sister to take on this responsibility.

"Brother, you should go quickly. Once you leave this place, it will be hard to find such an excellent place for cultivation in the entire prehistoric world. I am different from you. I can mobilize the resources of the entire Dark Abyss Demon League at will. And you..." Lin Niuniu insisted on her own opinion and spoke sincerely.

"Yes, this is a rare opportunity. I will also go to practice." Yan Huoyun thought it made sense and immediately sent a message to the Buddhist sect. Then he bowed to Yu Kai and Hou Tu Lingji and flew towards a high ground.

Hou Tu Ling Ji glanced at Yu Kai, nodded, and smiled at him, her eyes filled with gratitude. She knew that Yu Kai had always been considerate of her, Earth Mother Hou Tu, and had not troubled her. Then, she bowed to Niuniu and flew off into the distance.

Yu Kai wanted to say something else but was interrupted by Niu Niu: "Brother, go quickly!" After that, she took off into the air and flew towards the exit.

Yu Kai had no choice but to agree. He once again rushed into the light cluster where the Purple Sky Spirit Pearl was located. The chaotic aura there was the most intense, making it an ideal place for cultivation.

When Lin Niuniu flew to the entrance, she happened to meet several strong men in the top 20 of the Tianjiao list who were about to enter.

Without a word, she raised her hand, and a brilliant divine light shot out. Seeing this, the men hurriedly raised their weapons to block it. "Puff!" They felt as if struck by lightning, a surge of overwhelming force. They vomited blood and flew backwards like kites with broken strings.

At this moment, Yang Nianzhen, who had once again entered the Lingxu Secret Realm, also hurried over and witnessed the scene of these people flying backwards. He hurriedly waved his hand and released a stream of spiritual power, catching them steadily. Then, he shouted coldly at Lin Niuniu inside, "Who are you? Why are you blocking our way?"

Lin Niuniu was like a lofty, invincible goddess, her dignity evident. Standing in the void of Dao Yunxu, she looked down upon the crowd of geniuses with a cold gaze and uttered three words calmly: "Lin Niuniu!"

"Are you Lin Niuniu, the saint of the Abyss Demon League? Do you know what you are doing? This is the secret realm left by my master. Giving you a few places is already the most kind thing I can do. Do you still want to occupy this secret realm?" Yang Nianzhen shouted sternly, holding a long spear.

"Are you Yang Nianzhen?" Lin Niuniu put her hands behind her back, with a look of arrogance on her face.

"That's right, I am Yang Nianzhen, the son of Yang Jian! If you know what's good for you, retreat quickly. Otherwise, when I, the Saint of the Chan Sect, come in person, I will definitely wipe out your entire Dark Abyss Demon Alliance!" Yang Nianzhen was furious. It was one thing for Yu Kai to act lawless, but now this Dark Saint was so arrogant.

"Then you can die!" Lin Niuniu's face instantly turned cold, and she was not moved by his threat at all. She raised her hand and slashed out with another divine light. The powerful divine light seemed to cut through the void, making a "sizzling" sound, and slashed towards Yang Nianzhen fiercely.
