He guided the Yin-Yang energy to his hand, his fingers, and finally into the long sword he was holding. The blade lit up with black light, piercing the heavens.

In an abrupt motion, Qingfeng Li swung the Yin-Yang Saint Sword in his hand. With a sharp slicing sound, a long tear spanning from the sky down to the ground appeared in the air before him. Heaven and earth parted before the strike.

Ahead, there had been a ten-kilometer-tall mountain. Its peak had shot into the clouds, straight into the heavens. As Qingfeng Li's sword energy pa.s.sed, it sliced this ma.s.sive mountain straight in half.

Demonic beasts, plants, stone, and animals; everything in the black sword energy's path was cleaved in half. None of them could put up any resistance.

Seeing the immense offensive power of Qingfeng Li's strike, the Chief Commander stood beside him, his jaw agape. His eyes were filled with shock. This was the first time he had ever witnessed such a powerful sword technique.

Black Puppy and Sky-Devouring Snake were surprised as well. The power of Qingfeng Li's sword attack had exceeded their expectations. They had no doubt that, had the sword energy hit any of them, they would have been chopped in half.

Seeing the power of his strike, Qingfeng Li shook his head, dissatisfied. "According to what's described in the sword technique, once the sword is swung, heaven and earth should crumple, the ground collapsing upon itself," he muttered. "I still haven't mastered this first strike."

Beside him, the Chief Commander stuck out his tongue, shocked by what Qingfeng Li had just said. To him, this sword strike was definitely astonis.h.i.+ngly powerful. Even a master of the half-step saint realm would not be able to dodge such an attack. Yet Qingfeng Li had said that its power wasn't enough.

Qingfeng Li's brows furrowed as he began to study this sword attack anew. His body radiated a black light, this was the light of Yin.

The light of Yin had a unique cold energy. As it entered the Yin-Yang Saint Sword, the blade radiated a dazzling light. However, the light being black, it gave an icy cold impression.

Suddenly, a thoughtful expression appeared on Qingfeng Li's face. He noticed that, as he was circulating the light of Yin within his body, the Mortal Purgatory Body technique was giving out its own black light.

A daring thought surfaced in Qingfeng Li's mind. The Mortal Purgatory Body was a powerful technique that could suppress h.e.l.l itself. It, too, held a powerful icy energy, the same as what was contained within the light of Yin.

Qingfeng Li activated the light of Yin within himself. At the same time, he circulated the Mortal Purgatory Body as well. Two streams of black light formed within him. One stream was of a dark, cold energy; the other was the energy of h.e.l.l.

As the two streams of energy entered Qingfeng Li's Yin-Yang Saint Sword, the blade underwent a significant change. Upon its surface, black talisman scriptures formed, containing an unfathomable power that seemed to come from the Ancient Era. It was as though a Saint had awakened.

Even Qingfeng Li himself felt the cold as he held the Yin-Yang Saint Sword. To the others, it was even more unbearable.

Qingfeng Li activated his Yin-Yang Saint Technique, releasing a wave of powerful Yin energy from his Yin-Yang Spirit Nucleus into the long sword. Then, he swung it forward in an abrupt motion.

Crack, crack, crack, crack…

A series of crackles sounded in the air. Where Qingfeng Li's Yin-Yang Saint Sword pa.s.sed, heaven and earth shattered, sun and moon dimmed, the flow of time ceased, and mountains and rivers crumbled.

In the distance, everything had been shattered, sky, earth, mountains and rivers. It was as though the end of days was upon them. Plants and animals had all perished where the sword pa.s.sed, turning into scattered ashes.

Seeing the power of this sword attack, it was no longer just the Chief Commander who was left in shock. Xue Lin, Mengyao Xu, Black Puppy, and Sky-Devouring Snake all had their jaws agape, awed by the immense power of the strike.

Black Puppy took in a sharp breath. "I'll be d.a.m.ned," it said. "Your sword technique is ridiculously strong. If it had hit me, I'd have been chopped in half for sure."

Beside it, Sky-Devouring Snake also nodded. "That's right," it said. "Even though I've reached the Ninth level monarch realm, I still can't defend against that sword strike. This is the sword attack of a Saint."

Huff, huff, huff, huff…

Qingfeng Li drew in several breaths. His body had been drained of vital essence. He wobbled on his feet, nearly falling to the ground.

Sighing, Qingfeng Li spoke, "Such power… This sword technique requires far too much vital essence. There's no way I can use it twice."

Qingfeng Li felt that he didn't have nearly enough vital essence and spirit energy. After all, the strike he'd just released was the equivalent of an attack from a saint. He, on the other hand, was still at the half-saint realm. It was only natural that he couldn't use it too frequently.
