Qiao Beiting, who was beside him, subconsciously approached and when he saw the old man's black and purple chest, his expression became slightly solemn.

"I'm sorry, senior, I can't get rid of your poison." Chen Qingyang apologized.

If it is an ordinary poison, Chen Qingyang can still use the Taiyi magic needle to try it, but Chen Qingyang has no way to start this poison, because this is the first time he has seen a person who has been infected with the poison.

His understanding of the poison was only in the transmission.

The old man chuckled and said calmly: "It's okay, I know it in my heart."

He could not use his lifelong skills to force him out, and he did not expect a young man to cure him.

"Although I can't cure your poison, I can heal your internal injuries." Chen Qingyang said confidently.

Chen Qingyang, who mastered the fourth needle of the Taiyi Divine Agent, no matter how seriously the other party is injured, as long as he has a breath, Chen Qingyang can pull him back from the gate of hell.

"Then I'll bother you. No matter what the final result is, this piece of spiritual root belongs to you." Afterwards, the old man reached out and handed the spiritual root wrapped in coarse cloth to Chen Qingyang.

The old man has seen countless people throughout his life, so he can naturally see that Chen Qingyang really wants to cure him.

Chen Qingyang was not pretentious. After taking the spiritual root, he transferred it to Qiao Yao, and then took out the needle box to prepare to treat the old man's internal injuries.

"He is the Heart-Devouring Gu." At this moment, Qiao Beiting, who had never spoken on the side, suddenly spoke.

Chen Qingyang and others couldn't help but look at Qiao Beiting.

"Three Grandpa, what is the Heart-Devouring Gu?" Qiao Yao asked with confusion after hearing this.

"The Heart-Devouring Gu is an extremely terrifying poison. If I guessed correctly, the person who gave him this poison should have died." Qiao Beiting said.

The old man was stunned and nodded slightly.

"Why?" Qiao Yao asked.

"Because once the Heart-Devouring Gu escapes from the Gun, the Gun will die directly. This is a terrifying Gu poison that exchanges life for life. He can survive until now because he uses his lifelong skills to suppress the Heart-Devouring Gu." Qiao Beiting said.

"Senior, do you have a treatment method?" Chen Qingyang asked.

"If you want to remove the Heart-Devouring Gu poison, you can only force it out of your body. If it is killed directly, its highly toxic liquid will flow throughout your body. No warrior can withstand the venom of a Heart-Devouring Gu. Now the Heart-Devouring Gu is less than half an inch away from his heart. Now he is probably the only one who can save him." Qiao Beiting shook his head slightly and said.

"What does it mean?" Chen Qingyang asked in confusion.

Qiao Beiting looked at the old man with a deep look and asked, "You should be only one step away from that realm, right?"

The old man smiled bitterly and said, "One step difference is different, not to mention that I have not much time left."

The reason why the old man needs the longevity pill is to fight for time to break through the current realm, and perhaps there is still a glimmer of vitality.

"That may not be possible. What if I can help you break through?" Qiao Beiting said with a smile.

The old man narrowed his eyes suddenly, stared at Qiao Beiting for a long time, and then asked hoarsely, "What price do I have to pay?"

"It's very simple, I'll protect the Qiao family for ten years." Qiao Beiting said.

The old man's expression was slightly surprised, and he asked incredible ways: "That's the only condition?"

Ten years are a long time for ordinary people, but once the old man breaks through that realm, ten years are just a blink of an eye.

Qiao Beiting nodded.

"Okay, if you can help me break through, I, Wang Canglan, swear to my soul, and live and die with the Qiao family within ten years." The old man swears with a sonorous and powerful voice.

Qiao Beiting just asked him to protect the Qiao family for ten years. Now that he vowed to live and die with the Qiao family within ten years, it has shown his determination.

"I was right, you are the sword demon king Canglan. It is rumored that you died in that battle twenty years ago, but you didn't expect to be alive." Qiao Beiting's face was slightly shocked, and there was even a subtle sense of respect in his eyes.

The Sword Demon King Canglan is a terrifying figure who stood at the peak of the previous era, an invincible figure who once dared to challenge the Ling family, the leader of the eight super families with one sword.

Although he was defeated in the end, no one dared to mock Wang Canglan for being overestimated.

Because of that battle, the old monster in the Ling family who had lived nearly 150 years old was cut off by Wang Canglan with a sword and stained the sky with blood.

Wang Canglan's injuries were also left over from that battle.

Faced with the crazy pursuit of the Ling family, Wang Canglan had to hide his identity and survived until now.

As for when the Heart-Devouring Gu was in his body, no one except himself knew it.

"I can't even take up a sword now, and I'm no longer worthy of the name of the sword demon." Wang Canglan sighed.

Although Chen Qingyang did not hear the name of the Sword Demon King Canglan, it can be seen from Qiao Beiting's reaction that the dying old man in front of him was definitely an arrogant and powerful man.

No wonder he could teach such a terrible Fusu.

Chen Qingyang still remembers the masters of the four great realms with one sword, and even feels lingering fear.

"Grandpa San, do you want to use such things to help this old senior break through?" Qiao Yao asked with a frown.

Such things are the most precious things of the Qiao family, and they were obtained by the Qiao family at countless costs back then. The only thing Qiao Yao could think of helping the old man break through was that thing.

Qiao Beiting nodded slightly.

"But grandpa and the others will agree?" Qiao Yao asked.

"A bottle of fairy spirit is exchanged for ten years of protection by a powerful man in the Divine Pill Realm. They will definitely agree to such a deal." Qiao Beiting said confidently.

Hearing this, Chen Qingyang and Qiao Yao both shook slightly, and looked at Wang Canglan with a little surprised look.

No wonder Qiao Beiting had a little respect for Wang Canglan. It turned out that he was once a ruthless man with a perfect state of the state of great perfection, and he was one step away from breaking through to the transmigrated divine pill realm.

"But your current physical condition cannot withstand the power of the fairy spirit. Chen Qingyang, are you really sure to cure the injuries of Senior Sword Demon?" Qiao Beiting suddenly looked at Chen Qingyang and asked.

The Sword Demon King Canglan was a storied figure in the cultivation world a hundred years ago. It is natural for Qiao Beiting to call him senior.

Chen Qingyang didn't say anything nonsense and nodded directly.

"Okay, if you can cure Senior Sword Demon, my Qiao family owe you a favor." Qiao Beiting said solemnly.

Although Qiao Beiting is not the head of the Qiao family, his words can completely represent the Qiao family.
