Ye Xing naturally didn't know that Liu Ze and the Dove Demon Heart of the Gufeng Chamber of Commerce had also entered the Black Death Swamp and tracked him down.

At this time, he was leading the black slaves, and he was quickly flying towards the ruins.

After another half a day, Ye Xing felt that the miasma around him was getting thicker and thicker, and at the same time, some ordinary elixirs began to appear in the swamp.

These elixirs grow in the Black Death Swamp, and they all carry a kind of cold power, as if they have been infected, and there are still some differences from the normal growth of elixirs.

However, after Ye Xing investigated, he found that these cold powers were nothing, the medicinal properties of the elixir itself were exactly the same as those grown in other places in the outside world, and in the process of refining the elixir, as long as the alchemist was willing, he could first use the fire to refine these cold powers, and then the cold power in it would naturally disappear.

After finding some elixir, Ye Xing landed on a slightly drier mound.

One day, he felt that his body had been invaded by some miasma, and if it was not eliminated in time, it would slowly accumulate in his body and destroy his body.

Therefore, he had to prepare a special detoxification pill as soon as possible.

It's just that just after Ye Xing fell, roaring, from the hills, a fifth-order mud dragon rushed out directly.

It is said that it is a mud dragon, but it is actually a terrifying demon beast that looks like an earthworm, but it is extremely huge, several zhang long, and one end of it just rushed out of the ground, and it immediately cracked, forming a huge round tooth mouth, and the blood basin mouth swallowed towards Ye Xing.

At the same time, an extremely terrifying suction force was about to pull Ye Xing into the mouth of the mud dragon.

Looking at the dense sharp teeth, Ye Xing felt a chill all over his body, he reacted extremely quickly, and at the moment when the mud dragon was unearthed, he slashed out with a sword.

Poof!

Who knew that the defensive power of this mud dragon was extremely terrifying, and Ye Xing's sword with all his strength only left a fine mark several feet long on its body, and even its thick skin was not broken.

At this moment, Ye Xing was already desperate to break through to the fifth order, if he was now a fifth-order cultivator, how could he not even be able to break through the defense of a fifth-order mud dragon?

Seeing that Ye Xing still dared to resist, the mud dragon was immediately furious, boom, and the remaining half of his body was pulled out of the mire, bringing up a puddle of black sludge, and his heavy torso was pumped towards Ye Xing.

"Look for death!"

At this time, the black slave had already reacted, and with an angry shout, the Heavenly Demon Banner instantly rolled out.

Call!

Black demonic energy suddenly enveloped the huge body of the mud dragon.

"Bang bang bang!"

The black slave originally thought that the Heavenly Demon Banner was very easy to deal with the Yin Soul Beast, and it should be easy to deal with this mud dragon, but he didn't expect that this mud dragon's resistance to the black demonic qi of the Heavenly Demon Banner was extremely strong, and under the sweep of the Heavenly Demon Flag, it writhed wildly, and even rushed out of the black demonic qi package.

Ye Xing frowned, and he suddenly remembered that although the mud dragon was also one of the demon beasts, in fact, his wisdom was extremely low, and he only had the instinctive desire to devour.

The Heavenly Demon Banner, on the other hand, is actually an evil thing that can target the soul.

But this mud dragon has no thinking, and in addition to the fact that it lives with black mud in this black death swamp all year round, and devours a large number of miasma things, its resistance to this yin and evil thing is naturally extremely strong.

So much so that the Heavenly Demon Banner couldn't take the other party for a while.

The mud dragon was trapped by the Heavenly Demon Flag, and it also became angry, opened its huge mouth, roared angrily, and at the same time spewed out a large amount of sludge and slime towards Ye Xing.

Seeing these disgusting things, Ye Xing hurriedly retreated, only to see that after these sludge slime fell on the black death swamp, he suddenly let out a sneering corrosion sound, and the black fishy smell came, and the black mud on the black death swamp was corroded into big holes.

Fighting with this disgusting thing, Ye Xing was not interested at all, he directly took out the black gourd, opened the gourd stopper, and only heard a buzzing sound, and dense air devouring ants and fire refining insects flew out instantly.

Originally, Ye Xing was also worried that the Air Devouring Ants and Fire Refining Insects would not be used to the environment of the Black Death Swamp, but he didn't expect that after coming out, the Air Devouring Ants and Fire Refining Insects were obviously excited, and then turned into a black cloud, and the mud dragon was wrapped in a group at once.

The mud dragon, which was originally able to hold on under the black demonic qi, was attacked by the gas devouring ants and fire refining insects, and suddenly let out a painful cry, and its body rolled violently, while frantically spewing out highly poisonous mucus.

But the Air Eaters and Fire Refining Insects were obviously not afraid at all, and even the slime that could corrode the Black Death Swamp fell on these insects, but it was not able to corrode them at all.

After a moment of effort, the mud dragon that was still showing off its might before was completely paralyzed, and finally completely silent.

The power of the demon beast on its body has been completely absorbed by the air devouring ants and fire refining insects, and there is nothing left.

"Black slave, find out the demon crystal of this mud dragon for me. ”

After Ye Xing recalled the Air Devouring Ant and the Fire Refining Worm, he said to the black slave.

"Huh?"

Looking at the extremely ugly mud dragon in front of him, the black slave's face suddenly turned blue, he would rather Ye Xing let him fight with a martial artist than dissect this mud dragon and find its demon crystal.

But Ye Xing's orders, he naturally couldn't help but listen, so he could only cry and dig out the demon crystal.

Then he was extremely depressed and washed it with a lot of water before handing it to Ye Xing.

This mud dragon is extremely large, but the demon crystal is smaller than a normal person's fist, like a black crystal, and there is a faint black aura lingering in it.

"Don't underestimate this mud dragon's demon crystal, in this black death swamp, it can save your life at a critical time. ”

After Ye Xing said to the black slave, he directly took out a lot of elixirs from his body and began to refine them.

"Xing Shao, what is this for?" the black slave looked puzzled.

I saw that Ye Xing took out all the elixirs obtained from this black death swamp, and some of them were obtained from the Anbei Twin Demon Storage Ring, and quickly threw them into the Dan furnace.

After a stick of incense, a faint breath came out of the Dan furnace.

Only then did Ye Xing put the demon crystal of the mud dragon into the Dan furnace.

Then he began to refine it with the Qinglian Demon Fire.

After the black slave obtained the Qinglian Demon Fire, he was quite accomplished in refining medicine and bloodline, but after seeing Ye Xing's refining, he couldn't understand how he refined it at all.

In just a moment's effort, Ye Xing stopped refining, and at the same time, there were twelve more black pills in the Dan furnace.

"These are six detoxification pills, you take them and take one first. Ye Xing said after taking out six pills and giving them to the black slave.

"Xing Shao, I have already taken the Detoxification Pill. The black slave wondered.

"If you take it, you can use it, what so much nonsense. Ye Xing glared at him.

The black slave could only obediently swallow an elixir.

It's just that as soon as this detoxification pill entered his abdomen, a sharp pain instantly passed out of his stomach.

"Xing Shao, you're not trying to poison me, are you?"

The black slave screamed in pain, his face turned green, and his body was spasming.

It's so painful, it's like it's deadly.

Is this really an antidote pill? Not a killing pill?

The black slave was drenched in sweat, and his forehead was bruised, and this colic was almost crushing his body.

"I'm going to kill you, and I still need poison?" Ye Xing glanced at the black slave and said speechlessly: "I can't bear this pain, and I still want to become a strong man?" ”

"Yes!"

The black slave cried and sat cross-legged in a hurry, struggling to refine the medicinal power in his body.

If he hadn't known, Ye Xing wanted to kill him, he didn't need to work so hard at all, he thought that Ye Xing was going to poison him.

I was speechless in my heart, this is special, it hurts so much, it's like a thousand cuts on my body, and I said that I can't bear this pain, you can try it if you have the ability.

Xing Shao didn't know what kind of poison pill he refined, but he actually let himself test it, and he wouldn't festered and die when the time came, right?

While he was thinking wildly, he saw Ye Xing also pick up an elixir, swallow it directly into his abdomen, and then sit cross-legged and began to refine.

The whole process was extremely calm, he didn't see Ye Xing hum a word at all, as if he had swallowed not the same elixir as his own, but a candy.

No way?

The black slave was dumbfounded, if he hadn't seen Ye Xing swallow the detoxification pill that he had refined with himself, the black slave would not have believed that after this pill entered his body, Ye Xing would have behaved like this.

"I don't believe it, Xingshao can persevere, I can't persevere. ”

Gritting his teeth, the black slave began to frantically refine the medicinal power in his body.

With the refining of the medicinal power, the sharp pain came and went quickly, and it disappeared in an instant like the ebb of the tide.

Immediately afterwards, an extremely comfortable feeling was transmitted from the black slave's body, fluttering like a fairy.

"It's so comfortable, how can it be so comfortable?"

What shocked the black slave even more was that the originally somewhat depressing black death swamp air actually made him feel extremely fresh after taking the detoxification pill given by Ye Xing.

At the same time, a thin layer of black substance appeared on his body, seeping out of the pores, covering his body, and with a slight shake, it turned into ashes and dissipated into the air.

"Xing Shao, the detoxification pill just now ......"

Seeing that Ye Xing opened his eyes and also refined the detoxification pill he had taken, the black slave hurriedly asked, he now had too many doubts in his heart.

Ye Xing glanced at him and said, "The detoxification pill I gave you just now was refined by using the demon crystal of the mud dragon and the elixir of this black death swamp after Ben Shao analyzed the composition of the miasma of this black death swamp. ”

"Although the detoxification pill you took before also has the ability to remove miasma, the refiner is obviously only a fourth-grade alchemist, and the method used in the detoxification pill he refined is a general method to remove miasma. ”

"On the surface, it can prevent the miasma from invading your body, but in reality, it is not completely done, so there will still be some miasma left in your body. ”

The black slave was surprised: "You mean, my detoxification pill just now has no effect?"
