"Who are you scolding? Are you looking for death?" Ling Hu Yueyue's small face lifted, coldly asking.

  "Yu Yu, don't be rude." However, as soon as Líng Hú Yuē Yuē's words left her mouth, she was scolded by Líng Hú Hóng Fēi.

  Linghu Hongfei rarely got angry, so the people who were about to scold Chu Feng, such as Linghu Lun, also quickly shut their mouths.

  "Chu Feng brothers, now we are all on the same boat. If you discover anything, can you tell me the truth?" asked Ling Hu Hongfei.

  "Actually, there's nothing much, I think even if I don't say it, with your observational skills, Lenghu brother, you will soon discover it."

  "In fact, this black flame is the power that can enhance our boundary's strength." Chu Feng said.

  "Ah?" Chu Feng's words shocked everyone, including Liang Qiu sisters and Ling Hu Fei.

  "Chu Feng Gongzi, are you saying that this terrible black flame is the treasure left to us by the Jie Ling Xian Wang?" asked Dan Tai Xing Er.

  "That's right." Chu Feng nodded.

  "Nonsense! This black flame is so terrifying, just touching it will kill you, how can it be a treasure?"

  "Hongfei Ge, don't believe him at all. I'm watching him, he's just trying to get us killed." Linghu Yueyue said.

  "Believe it or not, it's up to you." Chu Feng's smile didn't diminish as he turned his head to look at Dan Tai Xiang'er and the others: "Since you've entered, there's no turning back. If you want to survive, you must merge with this black flame; otherwise, it's a dead end."

  "Only when merged with Kokuen will it not harm you, otherwise... it will regard you as enemies and take your lives."

  "So, apply your boundary technique and merge with it; the deeper you merge, the safer you will be."

  "I've reduced the threat of that black flame, as for how much it can be merged, it's up to you all." Chu Feng said this, and the magic seal in his hand changed, but the black flame actually penetrated the sealing power released by Chu Feng, slowly approaching Chu Feng and the others.

  At this moment, everyone present can feel that the black flame that pierced through Chu Feng's seal has indeed undergone a transformation.

  And that black flame seemed to have been controlled by Chu Feng.

  "Are you ready?" Chu Feng asked.

  "Hmm." Dongtai Xing'er and three others nodded simultaneously.

  Sigh——

  The next moment, the speed of the black flame suddenly accelerated, and then it wrapped around Chu Feng and others like a group of wild beasts.

  At this moment, Chu Feng and the other five people's faces all showed varying degrees of painful expressions.

  Tangtai Xiang'er is the best, Liang Qiu sisters are second, and Wu Ma Sheng Jie is relatively good.

  Only Chu Feng was relatively normal, but from his tightly furrowed brow and slightly trembling body, it could also be seen that he too was enduring immense suffering.

  "Uh..."

  Soon, Dongtai Xing'er let out a painful scream.

  Right after that, Liang Qiu's sisters were also like this, even Wu Ma Sheng Jie couldn't hold back.

  "Alright, you all get ready too." Ling Hu Hongfei said suddenly to Ling Hu Yueyue and the others after a round of observation.

  "Hongfei Ge, you're not kidding, are you? You really believe what that guy said?" Ling Hu Yueyue's face was full of surprise.

  "Yueyue, you're at least a Bug Patterned Brocade Guard, carefully sense that black flame." Ling Hu Hongfei said.

  "I've sensed it, and apart from its menacing aura, I couldn't sense anything else," said Ling Hu Yueyue.

  "Can't you sense it?" Linghu Hongfei seemed to understand something, so he deployed a formation, sealing off a small patch of black flames, and manipulated them: "Try again."

  Seeing this, Linghu Yueyue also sensed the black flame that Linghu Hongfei had sealed again. The next moment, her stunning face suddenly became extremely surprised: "Hongfei brother, could it be that this black flame is really the treasure left behind by the Boundary Spirit Sage King?"

  "It can't be wrong." Linghu Hongfei said.

  Upon hearing this, the others merely felt a chill run down their spines. After all, that black flame was so terrifying, so they were considering whether merging with it would really work?

  But Ling Hu Yueyue secretly took a glance at Chu Feng not far away, and there was a hint of complexity in her beautiful eyes.

  She really didn't expect that the one who saw through the black flame first wasn't her Dragon-patterned Robe brother Linghu Hongfei, but rather Chu Feng.

  Then, Ling Hu Hongfei also used formation techniques to reduce the threat of the black flames and let them in.

  Linghu Tiemian and others were very reluctant, but they had no choice but to face it.

  However, after Hei Yan sealed them off, except for Ling Hu Dōng Fēi and Ling Hu Yuè Yuè, everyone else was wailing in grief, that appearance, fundamentally did not resemble merging with Hei Yan, but rather simply enduring Hei Yan's torment.

  They must be regretting now, regret entering this place, because what's inside is completely different from what they thought.

  Some people even began to seek help from Linghu Hongfei, hoping that he could assist them.

  It may be due to the reason of the boundary sword that Ling Huo Fei and Chu Feng are in a state where they can still endure, although their faces are also painful.

  However, compared to others' pleas for help, Ling Hu Hongfei didn't even bother to respond because he had already discovered the secret of that black flame.

  By merging with Kokuen, you can obtain Kokuen's power. The deeper the fusion, the more power you will get.

  However, the power of Kokuen is limited within the land, so the more you want to get, the faster you need to accelerate the fusion.

  Linghu Hongfei is someone who wants to become a Saint Robe, so he naturally wouldn't miss this opportunity.
