All the pressure now shifted to the Heaven-Slaying Ancestral Sword Spirit. If the final strike failed, then everything would be over. At the very least, the Heaven-Slaying Ancestral Sword Spirit's will would be wiped out. For Yun Che, the only threat in the world would be silenced.

But Yun Che knew in his heart that completing this feat was no easy task. Because his strength had weakened again, it was almost impossible for him to use the power of his ancestors.

In such a difficult situation, he was unsure if he could block the final blow. However, he still held a trump card in his hand, which might be the key to determining the outcome of the battle.

"You are too happy too early." Yun Gu's face was terribly gloomy. At this moment, he no longer pretended to be kind and gentle as usual, and completely revealed the devil hidden deep in his heart.

The scars on his avenue, recently inflicted by "Never Regret Against Heaven," were now healing at a visible rate. Yun Gu's body shone with an intense golden light, like a blazing sun. This time, he was prepared to sacrifice all the extreme yang energy he had accumulated over tens of millions of years.

At the cost of overdrawing his life and collapsing his consciousness, the Sword Spirit of the Ancestral Zhutian once again aroused his ultimate power. He had already made up his mind to fight to the death.

This time, without the blessing of the extreme yin power, there was only the extreme yang power that belonged purely to him, which was also the purest and most fierce offensive power in this world.

"Although the power of the ancestor can increase my strength dramatically, this power does not belong to me after all, nor can I fully control it. Therefore, I was unable to unleash the true power of the first two swords, and this third sword is completely my own power."

Yun Gu took a deep breath, and his thin hands tightly grasped the Zhutian Ancestral Sword. He slowly closed his eyes and poured all his strength into the sword without reservation.

A chaotic golden light shone from Yun Gu's body and slowly converged on the Zhutian Ancestral Sword. At this moment, the Zhutian Ancestral Sword spirit seemed to transform into the most dazzling "star" in the outer chaos, making this empty and silent place once again possess a dazzling light.

“Yun Che, the fact that you were able to withstand my first two strikes is enough to prove that you are qualified to become the new Ancestral God. But unfortunately, I will not let you do as you wish. As long as I am still breathing, I will bury you forever in this outer chaos.” Yun Gu roared. At this moment, he had already decided to fight to the death with Yun Che.

The Sword Spirit of the Ancestral Zhutian had visibly aged. Yun Gu, who had previously had some sparse black hair, had instantly turned completely white. The wrinkles on his face deepened, as if the ridges of time had been magnified infinitely. His once bright and clear eyes had become cloudy, the traces of time sweeping mercilessly across his body.

“This sword is my last remaining strength, and it’s also the final blow that will end you! There’s no way you can block this sword of mine right now!” Yun Gu looked at Yun Che, who only had the power of a High-level True God at the moment, without a trace of pity on his face, nor any intention of holding back.

He wanted Yun Che to die, and wanted the world to return to peace and stability.

"This sword is called 'Hao Yang Zhong Yan'!"

The sword of the Heaven-Slaying Ancestor shone with golden light, and then a golden sun shadow slowly rose from the sword. This shadow seemed to contain a terrifying power that could destroy everything in the world. The moment this sword appeared, it seemed that everything in the world could be burned to ashes.

“Go to hell!”

At that moment, Yun Gu's white hair and shirt were completely consumed by the raging flames, and even his skin was burned with scarlet marks. However, he turned a blind eye to it. Right now, he had only one thought in mind: to send Yun Che completely into the endless hell, so that he would never be able to recover.

Yun Che felt the terrifying power contained in this sword. He no longer hesitated, and the Eternal Sky Pearl and the Qiankun Thorn instantly appeared in his hands.

"Space-time catastrophe!"

At this moment, Yun Che unleashed his final, hidden backup plan. He intended to utilize the space-time catastrophe to disrupt the order of time and space, thereby blunting the sharp edge of the Heaven-Slaying Ancestral Sword Spirit's fatal strike and drastically reducing its power. Simultaneously, he also intended to utilize the newly created space-time to absorb the will of the Heavenly Dao within it, regaining the strength to battle the Heaven-Slaying Ancestral Sword Spirit.
