"Don't you usually have a lot of guts? "He's not even afraid of killing people, but he's actually afraid of this?"

Gu Feng looked at Feng Zhidie, who was holding his shoulder with her small hand. Before coming in, she had a face full of indifference, but now, she was actually this scared and said in a funny manner.

"I'm still a little girl, of course I'm scared." Feng Zhidie pouted and said in dissatisfaction.

"Let's go. We'll go deeper in. This should only be the outer perimeter. The heavenly lake should be further in." Gu Feng said as he patted Feng Zhidie's head.

"But I'm afraid." Feng Zhidie said, feeling wronged.

"Don't worry, I'm here." Gu Feng gently smiled, his eyes looking deeper into the cave with anticipation.

With the help of the faint purple light, Gu Feng pulled Feng Zhidie as they slowly walked forward.

As Gu Feng and Wu Hao moved forward, the purple light gradually disappeared. Replacing it was a black and white light. The energies of Yin and Yang also became denser.

Right now, Gu Feng and the others were stepping on smooth stone slabs. They were neat and tidy, with walls on both sides and walls engraved with patterns. Furthermore, as Gu Feng moved forward, the space between the two sides became wider and wider.

After a while, Gu Feng's and Zhidie's eyes slightly focused as they looked in front of them with astonishment.

A ten-zhang long lake appeared in front of them. The lake was divided into black and white in color. The black and white bright gas converged in the air and intertwined with each other, forming the shape of a Taiji Yin Yang diagram.

"How amazing."

When Feng Zhidie saw this scene, the fear she had instantly disappeared. He let go of Gu Feng's arm and walked towards the Yin Yang Lake. Just as Feng Zhidie was about to leave, the purple lake began to churn.

Gu Feng's expression changed as he hurriedly grabbed her, "Miss Feng, be careful."

Dense Spiritual Energy surged out from his body and wrapped around them.

At the same time, the taiji diagram in the sky began to spin, and an extremely surging energy quantum lake gushed out. Immediately, a black and white energy pillar, that was over ten feet in size, shot straight up. The entire cave could not help but tremble under such a frightening energy pillar. Gu Feng's expression also changed slightly as he hurriedly withdrew.

Boom!

Gu Feng protected Feng Zhidie as she slid her feet along the ground for over ten meters before slowly stabilizing her body. As she gazed at the messy space, she could not help but wipe the cold sweat on her forehead. That energy was too great. If it weren't for him protecting Feng Zhidie, this little girl would have perished from the impact of that energy just now.

However, due to the impact from the energy earlier, the Yin Yang Energy that had permeated the heavenly lake did not disperse. It would still require some time to gather once again.

"Come, let's go in." Gu Feng used his right hand to stop Feng Zhidie, and under the little girl's surprised shout, he instantly jumped in.

As he jumped into the heavenly lake, Gu Feng instantly felt an extremely dense Spiritual Energy rushing into his body. At this time, both the incomplete Starfire Divine Technique and the Life and Death Heaven Stealing Technique in his body started to circulate at the same time. The incomparably pure energy unceasingly rushed into his body. These energies, along with Yin Yang energies, were strengthening his body.

"As expected of the Heaven Lake that can help a martial artist break through to the Pure Body Realm." Gu Feng couldn't help but lick his lips. The purity of the energy here was far beyond his expectations. If he could absorb it, then not only would he help a 9th layer martial art practitioner break through to the Pure Body Realm, he would also be able to break through to the Pure Body Realm with no cultivation at the early stage of the Martial Fate Realm. Of course, this was only a possibility. After all, the endurance of a cultivator was limited. If one were to put too much burden on a cultivator, their body would explode and they would die.

It was unknown when this little girl had already entered her cultivation state. She closed her eyes slightly as the spirit energy seeped out from her body and protected her surroundings. The natural energy from the heavenly lake, as well as the threads of yin and yang energy, slowly entered her body. Gu Feng observed for a while, and after making sure that there was nothing wrong with her, he started to operate the Fiery Charm.

A training seal was swiftly formed on his hand. His eyes were also gradually shut.

Within a few minutes, Gu Feng had successfully entered his training state. Immediately, a ferocious suction force slowly surged out from within his body.

As the suction force surged, the quiet Seraphic Pond immediately became restless. A shockingly powerful energy continuously drilled into Gu Feng's body like a waterfall.

The vigorous energy entered into Gu Feng's body and drilled into his dantian, his flesh, and even his bone marrow. Furthermore, the Yin Yang energy was also stimulating his flesh and blood, washing away his entire body.

Gu Feng looked inside his mind. He could see that a tiny bit of black impurities had been squeezed out of his flesh and bones by the Yin and Yang energies. However, even more Yin Yang energies entered his dantian under the guidance of the Life and Death Heaven Stealing Technique and entered the scroll.

Gu Feng's mind controlled the majestic energy that was being poured into his body as it swiftly circulated along the Qi Method route of the Sparks Divine Art. As it circulated, Gu Feng could faintly sense that the Qi Paths, bones, muscles, cells and so on within his body were frantically devouring the large amount of energy that had invaded his body.

However, the only thing that Gu Feng regretted was that the [Starfire Divine Art] was only an incomplete scroll. Although its absorption speed wasn't slow, it was countless times slower than the [Life and Death Tribulations] skill. If it was the complete Starfire Divine Art, the absorption speed would be several times faster than this.

However, even so, Gu Feng was already very happy. He could feel the spiritual energy in his body increasing, and he could feel his cultivation level increasing rapidly. This short period of cultivation was even stronger than when he had trained hard for a month and used the Life and Death Heaven Stealing Technique to devour the corpses of dozens of demon beasts.

Rumble …

After about two hours, Gu Feng's body couldn't help but tremble. At this moment, the spiritual energy in his body had already reached its limit. Peak of the 9th level of the Stellar Martial Realm, only two hours had passed.

"This Seraphic Pond is indeed a good item." Gu Feng's eyes revealed a surprised expression as he formed a seal with his hands. The Life and Death Heaven Seizing Art started to circulate within his body.

Strictly speaking, the Life and Death Qi and the Life Qi in his body were considered Yin and Yang Qi. However, they were even more domineering than the Yin and Yang Qi. He had already experienced the tyranny of the two energies of life and death. There was such a rich yin and yang energy within the Heaven Lake. How could he give up such a good opportunity?
