And it's hard to open and close it with this method, so Ji Cheng won't be stupid enough to use this method.

Of course, this is because Ji Cheng has a better way, so he doesn't need this stupid way. Using the Netherworld Qi, there must be a trace of dragon power combined to be able to enter and exit freely, just like the Nine Demon Dragons returning home.

The Nine Demon Dragons are also a kind of Hell Demon Beasts, and there were also Nine Demon Dragons in Hell before they were attacked by the Thunder Tribulation, but the original Thunder Tribulation destroyed the Nine Demon Dragons, so now there are no Nine Demon Dragons in Hell, but there are still dragon power and Netherworld Qi.

Ji Cheng took out the prepared breath and released it on himself, and then the entrance opened, and Ji Cheng quickly entered with the little centipede. Only a small part of the breath leaked, and the movement was not large, and only some small sea beasts nearby sensed these breaths and hurriedly fled......

The Nine Demon Dragon's lair was not as magnificent as he imagined, just a huge underground cavern, and there were some excrements that could be seen everywhere, which were filthy and messy. Of course, there won't be any smell, and these excrements are also treasures, and taking them back to fertilize those medicinal herbs in hell must have a great effect, so Ji Cheng collected them while walking.

It's better to go to the place where the Nine Demon Dragons rest, but it's only relatively speaking, but there are also a lot of good things in it, some storage rings, as well as scales, and nails shed from the dragon's claws, these are all treasures for refining weapons.

In the end, Ji Cheng found more than 3,000 dragon scales, nails shed from eight dragon claws, and some sea beast bones, although these sea beast bones cannot be compared with the top refining treasures such as dragon scales, they can be regarded as mid-to-upper refining materials, not to mention that they are also contaminated with the breath of some Nine Demon Dragons. If you can sell it outside, you can also exchange it for a lot of immortal crystals and pills, if you know how to refine the weapon, it is better, and you can refine it into a high-grade immortal weapon if you have excellent technology.

After collecting all the valuable objects, Ji Cheng began to collect the Netherworld Qi here, while the little centipede burrowed into the ground. Ji Cheng only remembered that since this was the lair of the Nine Demon Dragons, there must be something good underground, otherwise why would it build the lair here.

The little centipede was still depressed before, but after going underground, he became excited. Ji Cheng hurriedly communicated with Xiao Centipede: "What good things did you find underground?" ”

"Netherstone veins, and some stones ......"

"Leave me half of it, I can't eat it all......"

The level of the Hell Demon Beasts cultivated at the moment is not high, and they don't need too many of these things, half of them are enough. These things will also appear after the hell is upgraded, so Ji Cheng only allowed the little centipede to eat half of it.

"Forget it, it's enough to have Netherstone Veins and Stones, and there is no need for Netherstone Qi here. Leave some for the people who come behind, lest people run in vain......"

Ji Cheng thought about it and felt that he was still very kind, so he stopped collecting it and waited for the little centipede to come out. After waiting for a while, you can simply run the exercises and practice here.........

Half a day later, the little centipede came out of the ground, gave Ji Cheng a storage ring, and then returned to Ji Cheng's head. As for the Netherworld Qi here, there wasn't much left left, and Ji Cheng had absorbed ninety percent of the Netherworld Qi here after only cultivating for half a day.

Before leaving, he said: "I am also for their good, if it is too strong and they can't stop it, once the Netherworld Qi enters the body, it will be difficult to expel it, and it may damage the foundation." I'm still too kind......"

Out of the Nine Demon Dragon's lair, Ji Cheng took the little centipede deep into the sea to fulfill his original promise and let the little centipede eat enough. Of course, it wasn't nearby, and it took half a month to let the little centipede go and eat.

……

……

Half a month after Ji Cheng left, Geng Yunhan and the others finally came to the Nine Demon Dragon's lair, and there were more than thirty people in the group, and Cao Xuni and his senior brother were also there.

Geng Yunhan couldn't find a suitable candidate for a while, Cao Xuni and they had already got the map, Geng Yunhan could only inform the deacon of the sect to negotiate with Cao Xuni first. Geng Yunhan belongs to a high-level force, equal to Cao Xuni's sect, and no one chooses to report to the sect. So I could only choose to cooperate, and I searched the map for more than two months to find it.

According to the description of the map, the entrance was hidden nearby, and they accidentally discovered the entrance because they encountered a powerful sea beast chasing and killing, and they set up a formation nearby to explode itself and seriously injure the sea beast.

Because the formation is not very strong, it can only make the entrance show and not open, so they only need to arrange a more advanced formation to make the entrance open.

After opening, the aura will definitely leak, and the enchantment blockade aura must be arranged before those powerful sea beasts and strong people find out. So they hired some formation masters and put them in charge of setting up the formation and arranging the enchantment.

After the entrance was opened, they immediately entered, and then those formation masters threw out more than a dozen formation flags, quickly blocking the aura here and preventing these aura from leaking out......

"The breath didn't leak too much, and the sea beasts in the distance couldn't find out about the situation here, and as for those little sea beasts, they didn't have to worry about them being able to break in. But we also have to hurry up, take out the things here early, and get out of here as soon as possible, so we can't scramble and leave here to distribute ......," said one of the formation masters.

The others agreed, and everyone began to act, but as they went deeper, they found that there was nothing they wanted, and when they came to the place where the Nine Demon Dragons were resting, it was also empty......

Then they looked inside and out, and the result was that someone had come, and not long after they left, all the valuable things had been taken.

Geng Yunhan said with a gloomy face: "Damn, someone was the first to get there." It must have been the mother and daughter who did it......"

Cao Xuni's face is also very ugly, these people have not been separated since they got the map, and they have always kept the map, and no one else has seen the map, even her father and senior brother.

She agreed with Geng Yunhan's words very much, and she couldn't think of anyone else who would know about this except the mother and daughter. Only the two of them are the most suspicious, and they should have been following them all the time, rather than letting one of them take them.

The mother and daughter had hidden the map in a secret place, carrying half of it with them, on the condition that one person take it hostage and the other take it. The place of the transaction is on the lively street of Gucheng, where one hand delivers and the other hand is replaced.

So the mother and daughter are still in Gu Cheng now, and although they arranged for someone to watch them, they are basically not restrained and can contact others at any time. Maybe it wasn't necessary to sell the map to someone else in the process, but now it seems that it was definitely the one who copied a copy of the map and gave it to other forces.

Otherwise, how to explain that someone just happened to be the first to get there...... Take a look at the latest chapter of "Reopening Hell: The Rise of the Ten Thousand Worlds Claw Book House" to read it for free for the first time.
