The yellow poisonous mist was constantly expanding, and Gu Sanqian stayed in the center of the poisonous mist and watched around.

The surroundings were very quiet, only the poisonous mist formed by the yellow sand rubbed against the ground, and the 'rustling' sound made by rubbing against the rock wall. His gaze swept over the bend of the road, and the only place where he could hide was the bend of the road, but his gaze swept over these places and found no movement.

There are two exits to this place, one is the staircase not far in front of Gu Sanqian, which is exactly where he came. There was also an exit near the cave hall behind him, some distance from him, which was supposed to be where the Usho had been in and out before.

Uxiu was assassinated, and the hidden weapon came from the front of Gu Sanqian, and it was obvious that the murderer was directly ahead. The only places in front of you that can hide people are the dark corners under the stairs and the bends of the corridors, and these are the only two places where you can hide people.

His gaze swept over both places, but found nothing out of the ordinary.

"It can't be without one!" Gu Sanqian thought secretly in his heart.

There must be people in both places, either in one place or both. Because no one was able to kill Usho and escape in such a short period of time. Even if someone were so fast, it would be impossible to leave without a sound. And, of course, most importantly, he poisoned both places.

Although the poison is only a first-level poison, the superposition of multiple first-level poisons increases the power of this poison several times, and even if it poisons the cultivators of the immortal immortal fairyland, it can also give the cultivators of the immortal realm a certain amount of damage.

After being poisoned, it is absolutely impossible to leave without a sound.

Gu Sanqian was vigilant about these two positions as he walked towards the bend of the road closest to these two positions. The yellow poisonous sand that expanded outward was lowered by his deliberate cast, and it surged towards the bend of the road.

Just as he was about to reach the corner, his body jumped up, and he crossed the curve of the road, and at a glance, there was no one at the corner of the road. His eyes froze, and he focused on the shadows below the stairs.

There was no one at the bend in the road, and all that was left was the shadowy spot below the stairs.

"Whoosh!"

The man hiding in the shadows seemed to know that he couldn't hide anymore, so he sprinted out, then jumped up the stairs and ran outside.

Gu Sanqian swept the figure, only to see that the other party was dressed in black, covering his stomach with his right hand, and rushed out with staggering steps.

"If you want to run, it's not that easy!" Gu Sanqian snorted and followed.

The two rushed from the corridor to the house, from the inside to the outside, and then into the woods outside.

When he arrived in the woods, the man in black immediately sacrificed his flying sword and flew with his feet on it. It's just that he just flew into the air and staggered down. Seeing this, Gu Sanqian sneered a few times and rushed forward.

A few dodged Gu Sanqian caught up with the man in black, and a hundred meters away, he saw the man in black lying on the ground and rolling, he covered his head that had just hit the ground with one hand, and his head was bleeding, and he covered his stomach with the other hand, and rolled back and forth on the ground with the pain.

"Strange! First-level poison, even if there are several superimposed, it won't be enough!" Gu Sanqian's pace of rushing forward suddenly stopped.

He had just conducted a series of experiments on poisons, and he also had a deep understanding of the effects of poisons, and at this moment such a situation was obviously inconsistent with the results he obtained.

He had to be vigilant, and a few pills popped up at the sky in the direction of the man in black. He grabbed a handful of dirt on the ground, and the dirt quickly changed into sand in his hands, and he grabbed the sand in his hands and slowly leaned towards the man in black.

He walked forward step by step, tiptoe on the ground as he walked, his heels barely touching the ground.

When he reached a distance of about two or three meters from the man in black, a cold light suddenly shot out from his tumbling right hand, heading directly towards Gu Sanqian's heart.

Gu Sanqian's heels slammed on the ground, his body galloping backwards, his eyes staring at the cold light that was shooting in.

A silver nail about seven inches long was wrapped in the cold light. There was an impact on the silver nail, and before he could get there, Gu Sanqian felt the powerful impact, his ribs 'clicked' and broke under the impact of this force, and a heart-rending pain spread along the wound to all sides.

"Damn! I didn't expect the impact on this nail to be so strong that it could hurt me badly in mid-air. It's still a step slower!"

Gu Sanqian scolded in a low voice, a trace of fierceness flashed in his eyes, and he threw his right hand at a gallop behind him, and a handful of sand and dirt were spilled out by him.

The sand dispersed in the air, turning into grains of sand and hitting the nails, sparks flew in all directions, and the nails made a crisp sound.

Although the sand is small, but there are many of them, and the speed at which a large amount of sand hits the nails has obviously slowed down a lot, and Gu Sanqian's eyes are fast, and he grabbed the nails that shot at him and grabbed the nails in the palm of his hand.

"Poison?"

Gu Sanqian's heart was overjoyed, the moment he grabbed the nail, he felt the pain in his right hand like grasping a piece of red-hot iron, and the pain went down his arm like a plague towards his internal organs.

"It's so poisonous!" This was Gu Sanqian's second reaction.

The impact of this poison is very strong, and the corrosive force is also very strong, grasping it in his hand, his bones are broken inch by inch under the attack of the toxin, and his skin is just stained with this poison, and it begins to fester. In a short moment, a hole the size of a coin had appeared in his right hand, and the hole was deep enough to see the bone.

A green thread traveled upstream along his arm, passed through his neck, and then fell to his chest, and seeing that it was about to enter the heart, Gu Sanqian immediately mobilized twelve blood lines to the heart.

"Boom!" A huge roar came from Gu Sanqian's ears, and it felt like hitting his head against a steel plate three or four meters thick, and the whole world was spinning, and small golden stars were bubbling everywhere he could see. His heart stopped suddenly, and then his eyes tumbled, and his vision darkened, and his eyelids became extremely heavy, and he looked like he was about to close.

"Hmph! I can't help myself!" The man in black snorted coldly and got up from the ground, his face was still a little ugly, but his steps were like his gaze, extremely firm, and he walked towards Gu Sanqian step by step.

When he came to Gu Sanqian's side, he squatted down, he glanced at Gu Sanqian, whose eyes were about to close, smiled proudly, his right hand touched Gu Sanqian's Qiankun bag, his right hand just reached out, and before he touched Gu Sanqian's Qiankun bag, his right hand retracted like lightning, and his body was like a frightened rabbit jumping backwards.

"It's late!"

Gu Sanqian smiled, and a carp turned over and stood up. After standing up, he shook his right hand, and the hole that had been corroded by the toxin recovered at a speed visible to the naked eye, and the green line of his right hand extending to the heart was instantly swallowed by the twelve blood lines in the heart area.

After devouring this green line, the twelve blood lines have obviously grown a lot, and after consumption, only the length of an adult's fingernail is left, but now it has grown several times to the length of an adult's little finger.

"The second-level putrid poison, and the poison that is stronger than the second-level sand poison, is composed of at least three kinds of toxins. This poison can't be made yet, unless it consumes the origin of twelve blood lines to make it. ”

Gu Sanqian was happy, in the absence of a poison prescription, without his own creation, all his poison was based on perception. As long as he senses this poison, he can make it, at least through the origin simulation.

The man in black frowned when he saw Gu Sanqian's happy expression. The poison quenched on his silver nail was not an ordinary poison, and in order to prevent others from being able to detoxify, he even used three different toxins to form a poison superimposed. To cure this poison, it is necessary not only to know which three poisons they are, but also to understand what the proportion is.

Gu Sanqian was able to detoxify so easily, there must be some detoxification treasure in him.

Thinking of this, the eyes of the man in black lit up, he was also poisoned, he needed the elixir of detoxification, if he got the detoxification treasure on Gu Sanqian's body, his poison would naturally no longer be a problem.

The man in black moved, he rushed towards Gu Sanqian with an arrow step, his right hand flipped during the sprint, and the three silver nails were held in his hand, and then he punched Gu Sanqian.

Seeing this, Gu Sanqian totoed a little and stepped back.

As he retreated, he counted the numbers: "One... Two... Three... Ten... Twelve!"

"Boom!"

When Gu three thousand was counted to twelve, the body of the man in black suddenly fell to the ground, he tried to get up, but after trying several times, he still did not stand up, he lay on the ground and gasped.

Gu Sanqian shook his head and said, "For more than a second or two, it seems that there are some differences between different people." ”

He didn't seem happy with such an outcome.

At this time, the man in black shouted: "Impossible, how can this be." I'm a monk in the second level of the Human Immortal Realm, and you haven't even reached the Human Immortal Realm, how can you hurt me?"

Gu Sanqian smiled and leaned over to the man in black and said with a smile: "Yes, I haven't even reached the human fairyland, you know what else you are running?

You think that the sand you just threw out was thrown out in vain, and every time they hit the nail you shot at me, they will bring out a little sand poison, and countless sands will have countless points of sand poison, and these sand poisons will drift away with the wind, and part of it will fall on you. And when you were rolling on the ground before, I dropped a few chronic toxins in your direction, and now they have exploded together, and you naturally can't move. ”

After speaking, Gu Sanqian's face turned pale, and he said, "Say, why did you come to kill Wu Xiu? Who instructed you?"

The man in black was also very decisive, once he found that he couldn't escape, he sneered and said, "Hmph, you are delusional!"

Then he bit the poison hidden in his tooth and wanted to kill himself.

Gu Sanqian sneered: "Hmph! You actually committed suicide with poison in front of me?"

Gu Sanqian's right hand grabbed his arm violently, and a blood line drilled into the opponent's arm along his palm, and then returned to Gu Sanqian's palm after swimming around the opponent's meridians.

After this lap, the blood line was noticeably longer.

The man in black looked at Gu Sanqian with wide eyes, and he felt that the deadly toxin in his body had been dissolved, and it was removed so easily.

His heart sank to the bottom, he seemed to feel the anger of the person behind him after the mission failed, his heart trembled, and he bit the tip of his tongue violently, most of his tongue was bitten off by him, and a large mouthful of blood was spit out by him.

Seeing this, Gu Sanqian hurriedly grabbed his mouth with his hand, but he was still a step slower, and the man in black looked at Gu Sanqian with a relieved look, sneered a few times, and finally swallowed his last breath.

"Dead man, this is definitely a dead man! It was a dead man who assassinated my brother, and now there is a dead man. Gu Sanqian's brows furrowed and fell silent.

Earlier, he asked Ushu in the secret passage, 'Does Calculating Yan Tuo have anything to do with him?'

At that time, he just asked casually, he just had something incomprehensible about this matter, he just asked by feeling, but he didn't expect that this sentence had just been asked, and Wu Xiu would be killed.

Usho didn't answer him, but the dead man helped Usho answer.

This matter must have something to do with him, calculating Wuling Pavilion, calculating Yan Tuo, more or less there is a little reason for him in it. Who would do that, and why?

After thinking about it, there were still too few clues, and he sighed helplessly.
