When Yun Lintian drew closer to the pit, a sense of crisis immediately enveloped his entire being. He hastily created a protective barrier around him and opened his Eyes of Heaven. The scene in front of him made him instantly shock as he saw a dense Abyssal Energy gathered in the pit to the point he could not see the bottom.

Crack!

A small crack suddenly appeared on Yun Lintian's protective barrier while he was still in shock by the scene. He quickly regained his composure and was about to strengthen his barrier. Suddenly, a blue-colored solid protective barrier covered him along with Han Bingling appeared beside him.

She saw Yun Lintian's golden pupils and was surprised slightly. "You can see Abyss Poison?" 

Han Bingling was just guessing and believed this was Yun Lintian's eyes profound technique. However, to her knowledge, this kind of profound technique was scarce. Even her Frozen Moon Palace did not have such a thing. This made her curiosity about Yun Lintian grew further.

Yun Lintian didn't respond to her as he was frowning, thinking of a way to deal with this massive Abyss Energy in front of him. In fact, it didn't matter to him. He could leave it like that, but he felt uncomfortable when thinking of the Hazy Breeze Town turning into the land of the dead. 

Besides, he didn't know what was the purpose behind the Poison Valley's grand conspiracy by nurturing this Abyssal Energy. The more he encountered the Poison Valley, the more he felt the confrontation between him and them was inevitable one day. Then why not interrupts their plan when he has a chance? 

Seeing Yun Lintian was still silent, Han Bingling gave him time while observing the surrounding area in case she could find some clues left behind by the Poison Valley. 

"Since you've observed me back then for a good while, have you captured those black-clothed people?" Yun Lintian suddenly asked.

Han Bingling shook her head. "I've underestimated their decisiveness. They've committed suicide before I can capture them."

Back then, when she received a call for help from her subordinates that she arranged to protect Lin Xinyao, she immediately rushed to find her. As she arrived and saw Yun Lintian was curing Lin Xinyao with Profound Spirit Liquid, she was stunned and decided to watch him first. If he had an ulterior motive, she would immediately kill him.

Surprisingly, Han Bingling discovered Yun Lintian was sincerely treated Lin Xinyao. He didn't even take advantage of her. Han Bingling understood her disciple's charm and believed no man in this world could resist it. But this seventeen-year-old boy was so calm facing such a peerless beauty. This made her decide to watch him further instead of showing herself.

After Yun Lintian leaves the cave, Han Bingling followed the Poison Valley's members to capture them. However, they acted extremely quick and decisively by committed suicide on the spot before she could seal their power. 

Since she could not find a clue from them, Han Bingling could only trace their past movement and finally arrived here. It could be said it wasn't her intention to follow Yun Lintian.

Yun Lintian's frown grew deeper. "Aren't your Frozen Moon Palace fighting with them for thousands of years before? How come you didn't know their behavior?" 

Han Bingling did not reply to him directly but asked a question instead. "What's the most precious thing for humans?"

Yun Lintian answered almost in an instant. "Of course, it's life… So you are going to tell me they have never done this before in the past? That's why you've underestimated them?"

Han Bingling was surprised by Yun Lintian's intelligence. He could guess what she wants to convey instantly. "You're corrected. In the past, they didn't dare to kill themselves casually like this. This time, the Poison Valley has changed its ways completely. Not only they've become more sneaky, but their discipline has also increased tremendously."

Yun Lintian recalled the information that Yan Qi had told him. The Poison Valley is originated from a group of the Profound Beasts that fled away from the battle in the past. However, he didn't seem to detect any trace of the profound beast's aura within the Poison Valley's members he saw today. This proved the current Poison Valley had ordinary humans mixed in too.

"Do you know the origin of the Poison Valley?" Yun Lintian asked.

Han Bingling answered. "Of course, I know. They're originally created by the remnant of Profound Beasts that were slipped through the net in the earth-shattering battle four thousand years ago." While she was talking about this, she observed Yun Lintian's expression to see whether he knew this information. When she saw no surprise or frown on his face, she was certain Yun Lintian already knew about this.

The information related to the battle four thousand years ago was considered the top-secret among the nine palaces. Since Yun Lintian knew this, he could possibly hail from one of the nine palaces. Han Bingling knew every one of them very well, but she couldn't determine Yun Lintian's background.

Southern Divine Phoenix Palace can be eliminated as they only have a female disciple. Nine Profound Beast Palace is even more impossible since he has no Profound Beast's bloodline. Star Gazing Palace? He doesn't seem to have Star Power in his body. He shouldn't come from Blazing Sun Palace and Heavenly Sword Palace as they are mainly practicing sword, but he didn't even have sword intent on him. This leave with Azure Palace, Myriad Pill Palace, and Divine Thunder Palace. If it's the latter, that bastard Lei would tell me already, so only Azure Palace and Myriad Pill Palace left… Han Bingling's mind spun rapidly.

"Why Azure Palace can't eliminate them? It's been thousands of years already." Yun Lintian asked. He didn't understand. Was it that difficult to locate them? Wasn't Azure Palace the strongest existence in this world?

Hearing this, Han Bingling immediately eliminated Azure Palace from the pool and was determined Yun Lintian should come from the Myriad Pill Palace. It also made sense why he was so proficient in medical profound art.
