Not long after Ye Zichen left, the two from the Nether Heavenly Valley returned with murderous intent. When they opened the Sky Fire Sect's Heavenly Barrier Formation and saw the ten elders and protectors lying in a pool of blood, they felt like their brains were struck by a bolt of lightning and turned blank.

The next moment, endless rage burst out from their bodies. The two of them opened their blood-red eyes wide, roaring loudly like two angry lions.

"Ye Chenfeng, I swear that I will not be a human until I kill you." "Roar!" The Netherworld Valley roared hysterically. The billowing sound waves shot straight into the clouds, causing the clouds in the sky to violently fluctuate.

Skyfire Sect's Sect Master, Huo Yan, was an ambitious person. He wholeheartedly wanted to surpass Storm Valley and become the number one power in the Northern Snow Region.

Just when the overall strength of the Skyfire Sect had steadily risen, it had actually suffered a heavy blow. Not only was the reputation of the sect damaged, but the twenty-odd Elders and Protectors assigned to guard the division were also not spared.

This greatly weakened the overall strength of the Skyfire Sect. If it weren't for the sword source, and the fact that the Netherworld Valley was the pillar of the Skyfire Sect, Huo Yan would have killed them on the spot to vent his hatred.

"Sect Master, please calm your anger. We were too careless this time. Please give us another chance. We are willing to put on a show of merit and definitely capture Ye Chenfeng."

Looking at the gloomy expression on Huo Yan's face and feeling the vicious aura radiating from his body, the two men from the Nether Heavenly Valley felt their hearts tremble as they fearfully promised.

"Alright, I'll give you one more chance. If you let that Ye Chenfeng run away again, then you guys can face me head first." Huo Yan took a deep breath, suppressed the anger in his heart and said in a low voice.

"Sword Yuan, bring that Fu Youyue to see me. With her life, perhaps we can lure Ye Zichen out."

"Yes sir!"

Even though Fu Youyue was extremely talented, had the Azure Sky Peng bloodline, and was deeply loved by the Sword Yuan, at this moment, the Sword Yuan sacrificed her without any hesitation.

"Ye Zichen, since you are destined to not be able to become a disciple of my Sky Fire Sect, then I can only destroy you." Huo Yan's eyes flickered with a fierce glint as he quietly recited this in his heart.

… ….

Qingfeng Town, northwest of the Tianxuan Mountain, a simple and unsophisticated town.

After flying out of the Tianxuan Mountain, Ye Chenfeng disguised himself slightly, then went to Qingfeng Town and stayed in the only inn in the town. He took out the Cosmic Bag from which he killed Youwen Yuan and the others.

"I wonder how many mid-grade soul crystals they have."

Currently, what Ye Chenfeng lacked the most were medium-grade soul crystals. As long as he had enough mid-grade soul crystals and controlled the Sword Spirit Puppet, he would even dare to enter the headquarters of the Sky Fire Sect.

"Mm, the harvest is not bad. All these people have thirty-eight thousand soul crystals on them."

Ye Zichen rummaged through all the Cosmic Bag and found a total of thirty-eight thousand soul crystals. Adding the fact that he had stolen ten thousand mid-grade soul crystals from Youwen Yuan and exchanged them earlier, the number of mid-grade soul crystals reached eighty thousand. This was enough for the Sword Spirit Puppet to attack him.

"Sword spirit puppet, fuse!"

With a thought, the Sword Spirit Puppet flew out from a special Cosmic Bag.

When Ye Zichen put the fifty thousand mid-grade soul crystals into the Sword Spirit Puppet, its gem-like eyes shone with a dazzling brilliance, causing people to be unable to open their eyes.

"Rank 5 Mysterious Beast Sect. The Sword Spirit Puppet merged with fifty thousand mid-ranked soul crystals. Sure enough, it has the strength of a rank 5 Mysterious Beast Sect." Feeling the power of the Sword Spirit Puppet, Ye Chenfeng revealed a satisfied smile.

"I wonder just how strong this Sword Spirit Puppet will be after absorbing 80,000 soul crystals." Ye Chenfeng muttered to himself.

However, he did not blindly try it out. After all, although the Sword Spirit Puppet's attack power was terrifying, it still consumed a lot of energy.

"Thirteen low-grade earth-grade weapons, thirty-one top-grade spirit artifacts, forty-five high-grade spirit artifacts, twenty-three Spirit Level Soul Pills …"

After putting the Sword Spirit Puppet into the Cosmic Bag, Ye Zichen took out the other items in the Cosmic Bag and got a large number of Earth artifacts, spirit artifacts and spirit rank soul pills.

With the Great Heavenly Sword and the jade-green sword, he was useless against these spirit artifacts. He was prepared to find a chance to sell them all and exchange them for the mid-grade soul crystals that he needed.

"Eh, what is this?"

Suddenly, Ye Zichen found a dark blue grass that contained the power of lightning that was only half an inch tall.

"Heavenly Lightning Grass! This is Heavenly Lightning Grass!"

When Ye Zichen controlled his mind to sense this stalk of Thunderbolt Grass, information immediately appeared in his mind about this stalk of Thunderbolt Grass.

Heavenly Lightning Grass was a spiritual herb that grew from absorbing heavenly lightning. It contained a powerful thunder energy within it, so it was a first class body tempering spiritual object.

"Not bad, not bad, I didn't expect to get such a surprise reward this time."

After reaching the fourth level of the Six Meridians Divine Handle, Ye Chenfeng had tried several times to cultivate the Bone Forging stage. However, because the bones were wrapped in flesh and blood, it was extremely difficult to compress the energy into the bones.

"Let's try out the effects of this Heavenly Lightning Grass."

Ye Zichen adjusted his breath, then swallowed the Heavenly Lightning Grass into his stomach. Then, he slowly started to use the Soul Devouring Art to refine it.

All of a sudden, Ye Zichen felt a strong surge of lightning power explode from his stomach, traveling through his meridians and through his body. A huge pain instantly spread throughout his body.

Fortunately, Ye Zichen had cultivated his six meridians to the fourth level, while his physical body and meridians had undergone a qualitative transformation. He endured the pain from his body and silently operated his six meridians to forcefully compress the lightning power from the Heavenly Lightning Grass into his bones.

During the process of compression, Ye Zichen's flesh and blood were continuously penetrated by the power of thunder. A large amount of blood flowed out from his cracked skin, turning him into a bloody figure.

However, Ye Chenfeng completely ignored this. He relied on his superhuman endurance and clenched his teeth as he endured, slowly tempering the lightning energy from the Heavenly Lightning Grass into all the bones in his body.

After about the time for an incense stick to burn, all of the lightning energy contained in the Heavenly Lightning Grass was refined into his bones, which slightly increased the toughness of his bones, increasing his strength by 3000 jin.

However, the Bone Forging stage required too much energy. The effect of just a single Heavenly Lightning Grass was extremely limited.

"Sigh, the Bone Forging stage is really getting harder and harder to cultivate. How do I train my Bone Forging stage to the Mastery Stage?"

After refining a stalk of Heavenly Lightning Grass, Ye Zichen only managed to complete 1/10000 of the transformations in every single bone in his body. This allowed him to experience the difficulty of cultivating the Bone Forging stage.

"I guess I'll just take it one step at a time. If I really have to leave the Northern Snow Prefecture, I'll head to the vaster Northern Spiritual Region to find opportunities."

Ye Chenfeng muttered to himself, then threw a Spirit Level Soul Pill into his mouth. He then silently circulated the Soul Devouring Secret Art, in order to repair his body that was damaged by the power of thunder.
