As soon as Cheng Yun distinguished, he recognized several extremely rare poisonous weeds, which grew in harsh environments, and some even only grew in dangerous places like the West Pole Caishi Valley.

It takes a lot of effort just to get these poisonous weeds, not to mention the experiments after collecting all the poisonous weeds.

Behind this is obviously a huge organization, even more so than Cheng Yuan thought before. ap.

"How unreasonable!" Li Fei was furious after reading the jade slip: "You still dare to leave ...... grandiosely."

Cheng Yun took the jade slip, this is still the sound of the jade slip, she didn't deliberately cover it up, and the arrogant and wanton voice came out: "What if you find this place, it's just a bamboo basket for water. The monks of Zhongzhou are full of fat brains and stupidity, even if they set up the demon refining pool in the city lord's mansion, they can't find it. ......

Cheng Yuan didn't think that the man would know about the arrival of their group, but the two city lords were obviously targeted.

"The city lord will go back and investigate thoroughly, not to mention the city, even if it is a radius of five hundred miles, the city lord will turn it upside down!" Li Fei walked out aggressively, and the city lord of Tailang immediately followed, but glanced back at Cheng Yu and the others.

"Do you want to go back to the city?"

Cheng Yuan shook his head: "The city lord is at his own convenience, we still have to take a look around."

Lord Taylor nodded, "King Kong, stay and protect them."

The words fell, and the guards who had been behind them said yes.

Without waiting for Cheng Yuan to refuse, the City Lord Tailang and the City Lord Li Fei had already left in a hurry.

The guards left behind by the city lord of Tailang were not smiling, but Cheng Yuan always had a way to make him speak, and it didn't take long for her to learn a lot of recent news about Artemisia City.

The city lord of Artemisia City is a loose person, and most of the demon masters in the city are casual cultivators, and if they are bored in the city, they will cause trouble, and it is common to fight and fight each other.

Tyran is not limited, but happy to see the excitement. Compared to their two cities, the city of Chihao is chaotic, but more vibrant.

If it is really possible for the people behind the demon refining pool to hit the city, then among the three cities, the most likely is Artemisia City. Even the guards did not deny this.

"I think that person deliberately left the jade slip, and it is better to let the three city lords put all their experiences in the city. In this way, the attention to the outside of the city will be reduced."

The guard frowned: "Then why didn't you say it earlier?"

"The two city lords didn't give me this opportunity to say it. Besides, it would be good for them to thoroughly inspect the city, and maybe they would be able to find out some ghosts, snakes, and gods." Cheng Yun clasped his arms with his hands: "As for the outside of the city...... I'll leave it to you, Lord Guard."

"Me?" The man's eyes widened, and she looked whimsical.

Cheng Yun smiled: "Presumably, the guards are very familiar with the outside of the city, which places are rarely known, few people visit, and which places have hidden possibilities. You don't need to search through the carpet, you just need to find these places, encircle them one by one, and you may be very rewarded."

The guards were overjoyed when they heard this, and even though they were about to start arranging, they looked at Cheng Yuan hesitantly.

Cheng Yu hurriedly waved his hand: "Lord Guard, don't worry about me, this matter should not be delayed. In the future, the Demon Refining Pond will be discovered, and the Lord Guardian will definitely have a share of the credit."

Hearing this, the guards quickly left.

"You deliberately took him?" Xun Yan said.

Cheng Yun said, "We have our secrets, and the city lord of Tailang left him to protect as surveillance. And I don't like to be watched."

The two of them said and returned to the cave of the previous demon refining pool.

A burst of fire had left the place in ruins, and the air still smelled foul. I'm afraid these flavors will last for a long time.

Xun Yan pointed in the direction of the south and said, "This is to cover up, and the smell of that place is even worse, but if you come here first, you will definitely think that these flavors only come from here."

"Not bad." Cheng Yun and Xun Yan galloped in that direction.

It was a swamp, and that's where the stench came from.

Cheng Yun looked intently, there was nothing abnormal in the endless swamp, except for the bubbles that rose from time to time in the swamp, it was quiet and terrifying.

Side

There was a sound of 'snoring, snorting, heavy breathing, Cheng Yuan turned his head sideways, and saw Xun Yan's red eyes.

"What, did you find something?"

Xun Yan shook his head hard: "I just don't like it here."

"That's it!" Cheng said, "Sometimes, people's intuition is the most accurate."

Since they suspected that there was a demon refining pond in this place, they naturally wouldn't leave there.

Cheng Yun poured a little demon spirit liquid on the edge of the swamp, which was the favorite taste of the demon clan, and sure enough, in an instant, several stinky mud beasts hiding in the depths of the swamp popped their heads.

The stinky mud beast has a gentle temperament, can change its form wantonly, and likes to wrap itself in the sludge in the swamp, lying comfortably at the bottom of the swamp, if there is no external force to attract, it may be able to travel for thousands of years without moving.

But when it comes to getting into the swamp, they're great helpers.

Cheng Yuan clearly knew this, or because of Jiang Tu, what he contracted was a stinky mud beast.

The stinky mud beast absorbed the demon spirit liquid, and immediately advanced, and the sludge all over its body faded, turning into a ball of transparent colloids that was extremely clean, glowing with a little colorful fluorescence in the faint sunlight.

"Who said the Stinky Sludge Beast was ugly, isn't that cute?" Cheng Yun threw out a few silver wires with a wave of his hand, controlling the two stinky mud beasts at once.

The skunk beast didn't move when it was caught, but just stretched lazily.

Cheng Yu lifted the two stinky mud beasts out of the swamp and let them take off in front of them.

The skunk beast has no eyes, no face, and all perception depends on touch.

Cheng Yun stretched out his hands and touched the two stinky mud beasts respectively. According to Jiang Tu, communication with them is all up to divine sense.

So, Cheng Yun had a pleasant deal with him with his divine sense. Eventually, use two bottles of spirit liquid and ask them to help lead the way.

The stinky mud beast agreed, and immediately expanded, and its original fist-sized body expanded into a huge bubble, swallowing Cheng Yun and Xun Yan respectively, thus enveloping the two of them.

'Plop! Thump!

The two were dragged into the swamp in the blink of an eye, deep in it.

The stench that he originally thought did not hit, and Cheng Yu found that under the wrapping of the stinky mud beast, it seemed to have a layer of aura wrapped outside the body, isolating the muddy touch of the swamp outside, and isolating the stench and the frightening corrosion.

At this moment, the muddy swamp seemed to be flowing, and the skunk beast carried them through the mud with ease, moving forward at a speed that seemed to be very slow, but was actually extremely fast.

During this time, the Stinky Sludge Beast always accidentally bumped into some monsters hidden deep in the swamp.

When several high-level demon beasts passed by, Cheng Yun didn't dare to come out, and it turned out that the isolation ability of the stinky mud beasts was really strong, and these demon beasts didn't notice them at all, as if they were just passing through the mud.

Two hours later, a stone door appeared in front of them, and the skunk beast stopped.
