A blue sword light gathered into the Netherworld River, pouring towards Yun Bo and Mu Kill, the sword momentum was obviously faster and more subtle before.

It should be that seeing that the head of the family is about to wake up, several people have no scruples, and finally show the strongest unique secret technique of the Ghost Clan regardless of the gains and losses.

Yun Bo and Mu Shuben were not lightly injured, and the fierce battle for so long was already powerless, and in the face of the last blow of the other party's unreserved, the two of them were even more difficult to deal with.

With only one move, Mu Slay, who was seriously injured, was thrown out heavily, and although he was still holding the long sword tightly, he no longer had the strength to stand up.

Yun Bo was also forced to retreat again and again by the opponent's exquisite and imposing sword momentum, and he was in danger.

After only a few moves, the sharp sword blade slashed across Yun Bo's chest, and blood spurted out. Yun Bo took a few steps back, and slammed his sword on the ground, with a resolute look on his face.

"Kill!" Yun Bo let out a long roar, and with the last bit of strength, he killed the other party again.

At this time, Yun Bo was covered in blood, and his long hair was dancing wildly, like a god of war descending into the world.

Knowing that Yun Bo was already seriously injured, even the black-robed old men on the opposite side felt a little awe-inspiring in their hearts.

The black-clothed swordsmen who rushed into the mansion first hesitated and didn't dare to move forward.

"He's already seriously injured, and he doesn't have the strength to fight anymore, kill him!" a black-robed old man shouted at the black-robed swordsmen.

"Kill him, just wait for the head of the family to wake up, and then we will set foot in the Mu family. Another black-robed old man also shouted as if cheering.

Hearing the words of the head of the family, the black-clothed swordsmen lifted their spirits, shouted in unison, and brandished their long swords towards Yun Bo.

Yun Bo's eyes showed a look of absolute expression, this is the end of the crossbow, he doesn't take these black-clothed swordsmen in his eyes, but there are nearly a hundred black-clothed swordsmen who are pouring in like a tide, and those black-robed old men are also eyeing them, and if he continues to fight, he will definitely die.

But he can't go, for the sake of the Mu family, for his own duties, even if he tries his last strength, he can't go.

Mu Shu also struggled to stand up, his hands were trembling constantly, and he almost didn't even have the strength to hold the sword, but his body still exuded a strong fighting intent.

"Stepping on the Mu family, what a big breath. When Yun Bo and Mu Kill were about to use their last strength to fight desperately, Mu Hanyan's cold voice sounded in the air.

Immediately after, two sword rays slashed down in the air, and the air around them suddenly froze.

The black-clothed swordsmen who attacked Yun Bo and Mu Kill froze at their feet, as if they had been petrified on the spot, and a breeze blew, and the flesh and blood slowly disappeared from the wind and rain.

"Sword Saint, who are you?" Seeing the power of this sword, the expressions of the four black-robed old men changed.

"Young boy, quickly, destroy the ancestral hall, and don't let the head of the Ghost Clan wake up. Before Mu Hanyan could answer, Yun Bo shouted loudly.

Just seeing Mu Hanyan, Yun Bo was taken aback, and subconsciously wanted to let him leave, but then saw Ye Yanfeng's earth-shattering sword, and Ma changed his mind again.

He didn't expect that the "subordinate" who had been following Mu Hanyan since he returned to the Mu family was also a master of the Sword Saint Realm, and now he could only rely on him to prevent the head of the Ghost Clan from waking up.

Mu Hanyan's heart froze, and she also felt the gloomy aura exuded by the ancestral hall, as well as the increasingly strong bursts of evil intent.

At first, she was a little strange, the situation was so critical, Yun Bo and Mu Kill not only didn't want to escape, but also fought to the death with each other, only then did they understand that they wanted to prevent the awakening of the head of the Ghost Clan. Without thinking about it, she also knew that Yun Bo and Mu Kill were trying to eliminate hidden dangers for the Mu family.

Seeing the scars on the two bodies and the absolute appearance of their eyes, Mu Hanyan was deeply moved by their loyalty.

The reason why the Mu family has been able to pass on to today after hundreds of thousands of years of ups and downs is that in addition to the unremitting efforts of generations of Mu family members, it is also inseparable from these loyal Mu family dead.

Without hesitation, Mu Hanyan flew up and slashed towards the ancient ancestral hall with a sword.

Hearing Yun Bo's words, the black-robed old men had already guessed the origin of Mu Hanyan and the others, how could they let her succeed.

As soon as the figure moved, the four old men blocked in front of Mu Hanyan at the same time, and four sword rays swept through, like a piece of water from the River Styx, pouring towards Mu Hanyan.

"Be careful!" Yun Bo exclaimed.

The Demon Clan's evil art is too weird, although the cultivation realm has not improved much, but the subtlety of the sword momentum makes it very difficult for him to deal with even the Sword Saint realm, not to mention Mu Hanyan, who has just been promoted to sword master.

Without Yun Bo's reminder, Mu Hanyan had already flown back. The sword momentum of these four black-robed old men was the same as that of the young man before, but they were masters of the ninth order of the sword master, and the same sword momentum was not only more subtle in their hands, but also more powerful.

With the strength of her third-order sword master, even if she has the ability to defeat the enemy beyond the rank, it is impossible for her to be their opponent.

Mu Hanyan retreated quickly, and the four black-robed old men came faster, but in an instant, a few sword rays completely enveloped Mu Hanyan.

At this moment, a snow-bright sword slashed out, as if tearing open the heavens and the earth, and the green sword that was like the water of the River Styx was also darkened under this sword.

"Choking" There was a long sword roar, and several black-robed old men were shocked back a few steps, looking at Ye Yanfeng who was blocking in front of Mu Hanyan with a surprised expression.

Although they had already seen the strength of the Sword Saint Realm from the previous sword, after the battle, they knew that the strength of the Night Cliff was stronger than they imagined.

Ye Qifeng also took a step back, and her expression became solemn.

He has enough confidence in his own strength, even if he is also a sword master, and even in the eyes of many people, there is only one chance of one move in his hands. However, the four black-robed old men in front of him were obviously only the ninth order of the sword master, and they took his sword together, but they only took a few steps back, and at most they were slightly injured.

It is worthy of being a ghost clan that was once so powerful that even the royal families of all countries had to be held hostage by it, and even he had to deal with this kind of evil magic that could forcibly increase his combat power without sacrificing his longevity or cultivation.

"I'll stop them, and you will destroy the ancestral hall. Ye Qifeng said to Mu Hanyan.

"Okay, be careful yourself. Mu Hanyan also knew that in the face of these four black-robed old men, she couldn't help much, and destroying the ancestral hall was the top priority.

As soon as Mu Hanyan's words fell, the ancestral hall shook violently again, releasing a more powerful Yin and Cold Qi, and the Hanxiao Sword in Mu Hanyan's hand also let out a pleasant hum.
