Outside Thunder King Valley.

Everyone, upon hearing Ye Suxin's words, stared blankly at the young man in black, eager to know what choice he would make, whether to push through defiantly or yield to her words.

After all, none of these onlooking cultivators had truly witnessed Yun Xiao's combat prowess; what they saw was merely his shadow clone from earlier at the Thunder King Main Hall, and the sudden shift from defense to attack just now.

Even though Ye Suxin had mentioned after leaving the Thunder King Main Hall that the young man named Xingchen was not to be underestimated, now, however, the situation involved two geniuses from the Killing Heart Sect's Seeking Origin Realm joining forces, planning to execute the Yin Extreme Killing Skill, which is said to be greater than the sum of its parts.

Even Ye Suxin thought this way; with her strength now recovered to ninety percent, along with Tong Baisha also at the Origin Seeking Realm Early Stage, she believed they could take down this young man who had just broken through to the Peak of Qi Seeking Realm.

"Tsk tsk, it seems sparing your life in the Thunder King Main Hall did not teach you any lessons!"

Hearing Ye Suxin's threatening words, Yun Xiao shook his head, speaking with helplessness. These geniuses from the Hidden Killing Sect were arrogant by habit, completely unaware of the true gap between them.

In reality, Yun Xiao had no grievance or enmity with the Killing Heart Sect. If Tong Baisha hadn't attacked, he wouldn't mind letting Ye Suxin go. Unfortunately, this woman was oblivious to the situation, leaving him no choice but apologize.

With Yun Xiao's disposition, there would certainly be no intent to show mercy, and upon hearing this, Tong Baisha was the first to make a move.

"Rejecting goodwill to choose punishment, then you can't blame us!"

Ye Suxin was evidently provoked by Yun Xiao's words, and after another low shout, a similar aura to that of Tong Baisha's arose from her body.

"Yin Extreme..."

"Killing Skill!"

As Ye Suxin spoke the first two words, Tong Baisha solemnly completed the next three. With these five words uttered, everyone noticed that the air at the entrance of Thunder King Valley seemed to become colder, as if a chilling wind from deep hell was blowing.

"Is this the Yin Extreme Killing Skill?"

Many onlookers knew the famed secret technique of the Killing Heart Sect, but none had truly witnessed it before, or perhaps those who had seen it were mostly already deceased.

"Quite interesting!"

Two gusts of cold wind brushed past from left to right, and Yun Xiao sensed the peculiarity within them, sparking his interest. This method of divided advance and joint attack seemed to be incited by something within the two individuals.

With Yun Xiao's experience, he immediately had some insight, thus he didn't panic. With his current strength, even these two geniuses from the Origin Seeking Realm Early Stage together couldn't pose much threat to him.

It was clear that both Ye Suxin and Tong Baisha were cultivators with Yin attributes, which perhaps was considered during talent selection at the Killing Heart Sect, as these attributes were vital for learning some secret techniques there.

This was somewhat reminiscent of the lineage poised in the Flying Flower Empire on the Hidden Dragon Continent, except Young Master Flying Flower Ye Shimei's Yin attribute paled in comparison to these two, like a child facing a giant.

The intense Yin attributes seemed to render the chilling winds even more eerie, and as those auras approached, Yun Xiao began to sense a slight disturbance within his soul.

But alas, while this Yin Extreme Killing Skill proved unbeatable against ordinary cultivators, its encounter with Yun Xiao was fated to be ineffective, merely impacting him fleetingly.

Swoosh! Swoosh!

Two consecutive wind-breaking sounds emanated from the air, accompanied by a transparent sword tip and a short blade abruptly attacking from somewhere, targeting Yun Xiao's throat and chest vital areas.

At this moment, many finally understood the true essence of the Yin Extreme Killing Skill, its ability to create an illusion of stealth during direct combat.

Amidst the endless chilling wind, an opponent's soul undoubtedly would be affected, obscuring their ability to sense the enemy's position. This was when the Killing Heart Sect cultivators abruptly struck, akin to launching a stealth attack.

Moreover, Ye Suxin and Tong Baisha coordinated seamlessly, their moves appearing simultaneous, striking with a knife and sword as if executed at the exact same instant. To outsiders, no matter which direction Yun Xiao chose to evade, a weapon seemed poised to meet him.

This unavoidable situation caused onlookers to widen their eyes in shock. However, the young man in black, Yun Xiao, stood unmoved, not even granting a sliver of motion at this crucial moment.

"Is this another clone afterimage?"

Just when everyone reflexively thought Yun Xiao was about to use his special afterimage movement technique to dodge this fatal hit, they saw an earthy yellow object rise from the youth's body.

Clang! Clang!

Two crisp sounds rang out in succession, and everyone clearly saw at the end of Ye Suxin and Tong Baisha's blade and sword attack, right at the vital point of Yun Xiao's throat and chest, appeared two objects resembling mud.

These objects that merely looked like yellow earth had extremely strong defense, even being able to block the killer strike of two geniuses from the Killing Heart Sect, which was astonishing enough to make jaws drop.

It's known that the specialty of the Killing Heart Sect isn't just stealth attacks; the sharpness of their weapons is also a key reason for their ability to kill in one strike.

Even though Tong Baisha's Earth Rank Middle Level weapon was destroyed under the thunder of the Thunder King Main Hall, the short blades in Ye Suxin's hands were two genuine Earth Rank Middle Level weapons.

Such a grade of weapon couldn't even pierce through that mud-like object. At this moment, no one regarded that object as ordinary mud; it must be a powerful Defensive Meridian Technique, and of high grade.

"It seems after continuous improvement in physical strength and Meridian Qi, the defensive power of the Earth Burst Stone Lotus Armor has increased substantially!"

Perhaps only Yun Xiao himself was aware that the stones protecting his throat and chest were a unique manifestation of his Earth Surge Stone Armor. Such Heavenly Materials and Earthly Treasures, rarely seen even in Nine-layered Dragon Cloud, could block the deadly strike of two geniuses from the Killing Heart Sect without difficulty.

Hoo... Hoo...

With a gust of yin wind, the failed strike didn't slow Tong Baisha and Ye Suxin's reaction at all. Their weapons swiftly moved, and even Yun Xiao couldn't sense the real position of these two in the next moment.

The wonder of the Yin Extreme Killing Skill lies in it making cultivators feel shrouded in fog when facing experts from the Killing Heart Sect, not knowing when they might strike lethally, leading to an inexplicable death.

Yet with Yun Xiao's powerful Soul, that hazy feeling lasted only for the instant Ye Suxin and Tong Baisha hid in the yin wind; he then could clearly see the positions of those two figures.

"It's only polite to return the favor; taste the skills of Yun Xiao!"

Since Xu Huang had already exposed his identity, Yun Xiao decided not to hide his true identity any longer and used his real name. Immediately after his words fell, the numerous cultivators present felt the previous icy chill of the yin wind seemingly decrease slightly.

Suddenly, in Yun Xiao's right hand emerged a blood-red flame, and as this flame appeared, the endless yin wind seemed instantly affected.

Fire is the most robust and yang attribute entity, especially like the Ancestral Vein Fire in Yun Xiao's right arm, a divine artifact that is the nemesis of all yin and cold attributes. Although his Meridian Qi Cultivation was far inferior to Ye Suxin's and Tong Baisha's.

Yet this Ancestral Vein Fire, transformed from the Blood Moon Jade, was not an ordinary flame. In just a moment, the chilling atmosphere created by the two Killing Heart Sect geniuses vanished completely.

Without the cover of the yin wind, Tong Baisha and Ye Suxin's presence was naturally exposed, meaning that merely one blood-red flame broke the so-called Yin Extreme Kill Formation.

But Yun Xiao's techniques didn't stop there; after burning away the yin cold qi, his left hand reached out again, gently slapping, and then a massive Ice and Fire Giant Dragon suddenly appeared in everyone's sight.

"What is that thing?"

The spectators, who had never seen such a marvelous scene, widened their eyes. Even Xu Huang, an Origin Seeking Realm Middle Stage expert, had a gleam in his eyes because he sensed a threat from that Ice and Fire Giant Dragon.

Previously, when Xu Huang and others arrived at Ancient Moon City Yang Family, Yun Xiao had already used the Ice and Fire Giant Dragon to kill Yang Dingshan. Therefore, they had not seen the power of this dragon.

But as an Origin Seeking Realm Middle Stage expert, Xu Huang instinctively felt a threat, suggesting that Yun Xiao, who hadn't been seen for quite a while, was even stronger than during his time at the Yang Family.

Bang!

Suddenly, the Ice and Fire Giant Dragon rammed its huge dragon head directly into Tong Baisha's chest, immediately sending him flying backward like a kite with a broken string.

"Splash!"

After all, Tong Baisha had just broken through to the Early Stage of the Origin Seeking Realm recently, and his combat power was only slightly stronger than Yang Dingshan's, even inferior compared to Tang Yuanmu. Therefore, how could he withstand the collision from the Ice and Fire Giant Dragon? In the air, blood sprayed wildly, and his breath plummeted.

"Chi Yan!"

Just as everyone watched Tong Baisha severely injured and flying back, retaining a hint of breath, from the mouth of the black-robed youth suddenly came an unexplained shout.

Whoosh!

Then, a fiery red shadow suddenly shot out from somewhere, pouncing toward the near vicinity of Tong Baisha's falling body at lightning speed, followed by a small fiery red glow detaching and directly bombarding this Killing Heart Sect genius.
