The top grade of the ground steps, according to the demon lock sword.

The sword qi carried the sound of wind and thunder to split the oncoming black qi, penetrating through the heads of the killers of the Seven Killing Palace, and dispelling all the strange black qi entrenched in it.

The killer of the Seven Killing Palace, who behaved like a demon beast, instantly stared at his legs, closed his eyes, and fell down after staying in place in a daze, but the body that was still alive just now also began to shrivel and shriveled at this time, and in a few breaths, it was completely reduced to a lifeless dry corpse.

It is obviously unrealistic to try to find clues from the dried corpses.

But just when Su You was about to give up the investigation and was about to walk forward to take a look, the black qi that had just been forced out of the body of the killer of the Seven Killing Hall by the Demon Lock Divine Sword formed a black curtain in front of him, blocking him from all directions.

Before Su You could react, black qi burrowed into his head.

"This black gas... Yes! ”

Unexpectedly, the black qi directly drilled into the sea of knowledge, turned into a pitch-black worm, and began to attach to the sun and moon hanging above the sea of knowledge, constantly gnawing and devouring the spiritual power that circulated in it.

The sudden pain was like falling into a netherworld purgatory, and the spirit was constantly whipped and torn, and Su You fell to the ground with his head covered and curled up.

The pitch-black worm seemed to become stronger after gnawing and devouring the spiritual power in the sea of knowledge, and the huge sea of knowledge began to become fragmented, Su You only felt that his consciousness was gradually blurring, as if there was another consciousness trying to control his body.

"It seems that this is the real reason why those Seven Killing Hall killers lost their minds and became like demon beasts."

Suddenly, Su You, who was curled up and fell to the ground, suddenly opened his eyes, and a golden flame ignited in his pitch-black pupils, and then the power of the Extreme Yin Pole Yang Yuan Dan in the Dantian instantly exploded, and the Sun True Fire, Taiyin True Fire and the origin power of the Nine Heavens Xuanhuo wrapped his whole person, and at the same time flowed through the limbs and hundreds of remains, like a tsunami, the waves of flames swelled up and down in the Sea of Knowledge, instantly engulfing the pitch-black worms attached to the sun and moon over the Sea of Knowledge.

The ultimate yang and the ultimate yin, plus the Nine Heavens Xuanhuo, which represents the fire of life.

The pitch-black worm was swallowed up by the flame wave and was immediately burned into a cloud of black gas, and it slipped out of Su You's sea of knowledge as if it had escaped, and even the black curtain that covered the sky and did not allow Su You to leave quietly dispersed at this time.

And Su You, who was still being tortured and rolling on the ground just now, got up from the ground like a nobody, and easily patted the dust on his clothes.

"Could it be a strange demon beast that feeds on the cultivator's soul and spirit?" Seeing the black qi dissipating, Su You, who didn't want to catch up, thought to himself: "But I can't perceive the vitality that all living beings should have, and it's more like a puppet controlled by people... Could it be that there are still living people in this secret realm besides the people of the three major killer organizations? ”

While thinking, Su You hurried towards the town in front of him where the outline could be faintly seen, he wanted to know what was going on with the rest of the three major killer organizations now, he didn't want to be left alone or alive before he found anyone.

Along the way, there was no black gas to stop it.

Su You was able to arrive at the ruins of the nearest town after an hour or two.

But what is surprising is that the ruins of the town in front of him are not fake, and they will not turn into yellow sand and drift away in the wind, Su You can clearly perceive the long and thick history of this town when he puts his hand on the mottled city wall.

At the same time, it can also be seen that killers from the Seven Killing Palace, the Broken Military Tower, and the Dragon Slaying Pavilion have gathered here from all directions.

These people all looked normal, but the expressions on everyone's faces looked a little weird, and they seemed a little depressed and a little panicked.

Among them, the three major killer organizations who had settled in the town to recuperate gathered together and whispered, "Well, did you see anything on the way here?" It's just a very strange black gas, and after being eroded by the black gas... The same people who have become very strange..."

The killer of the Dragon Slaying Pavilion immediately nodded and replied, "Could it be that you have all encountered it?" On the way here, I also met a colleague who seemed to be controlled by something, no matter how I called him, he didn't react, and even attacked me in turn, if it weren't for my superior skills, I was afraid that today I would have become a corpse and stay in this secret place forever. ”

"Looks like we've all been in a similar situation on the way here." At this time, a killer from the Seven Killing Hall looked at Su You who was standing by the wall, obviously knowing that Su You was arranged by the greedy wolf, he said to Su You: "What about you? Looking like you're in a similar trouble? It's better to say it so that everyone can think about what can be solved together. ”

"Yes, yes, young man, you can talk about it too." The killers of the Broken Military Tower and the Dragon Slaying Pavilion responded one after another.

Seeing that everyone's eyes turned to him, Su You didn't hide it, and said bluntly: "I met four or five killers of the Seven Killing Hall who were eroded by the black qi on the road, they seemed to have lost their consciousness and were controlled by the black qi, and wanted to kill me like demon beasts, fortunately, I was a good skill to defeat them, otherwise I would have become a corpse and stay in this secret realm forever." ”

As soon as the words fell, the killers gathered here all sighed that the things they encountered were the same, only the people they met were different.

"It seems that this secret realm is much more dangerous than we imagined," a Dragon Slaying Pavilion killer said in a deep voice, "It's just that now we don't know when we will encounter that weird black qi, and we don't know if we will become like those colleagues..." Not to mention that the top of us was asked to look for something in the secret realm, but we haven't found anything yet..."

"What are you afraid of! The soldiers will block the water and cover the earth! I don't believe that a cloud of black gas can still block the knife in my hand! ”

At this time, a tall killer of the broken military building stood up with an unconvinced face, and he walked towards the outside of the city with the long knife in his hand, and said as he walked: "I'm not afraid, if the black gas comes, I'll cut him with a knife!" ”

After saying that, the Killer of the Broken Military Building left the ruins of the town.

But the others did not get up and followed him away.

At this time, the killer of the Seven Killing Hall who took the initiative to mention Su You just now walked to Su You's side with the other killers of the Seven Killing Palace, and said in an extremely low voice: "We know that you were arranged by the Lord of the Greedy Wolf Hall to enter the secret realm, so do you want to act with us later?" After all, it is the first time for everyone to face this situation, and one more person can also have more strength. ”

"Okay, I don't have a problem." Su You did not refuse, and immediately responded with a smile.

The Seven Killing Hall Killer, who proposed to cooperate with his peers, smiled and said, "In that case, let's rest here for a while, and after an hour, we'll set off to the deeper depths of the secret realm to see if there's anything we want to find." ”
