Ou Xiaolu thought about it, and this was also the truth, so he put this thing aside and began to seriously look for it in the treasure of the Demon Dragon King.

After looking carefully, Ou Xiaolu really found some more things, like a map of the third-layer underground world, and the map was full of various hidden passages or something.

There are also two secret bases of the Demon Dragon King, among these two secret bases, there is a place used to make and train the servants of the Demon Dragon King's dependents, and there is a completely biological splicing laboratory, which can be seen that the Demon Dragon King will become three heads, which should be the research results of this laboratory.

Finally, the map also pointed out a yellow mine controlled by the Demon Dragon King, where a large amount of gold could be produced every day, and it was through these years that the Demon Dragon King had managed to build his secret base.

Of course, Ou Xiaolu understands why the base of the Demon Dragon King is so expensive, now their location is about one hundred to one hundred and fifty meters underground in Xinxiang, and there is no direct way up and down, if they want to transport a little thing in, but the freight is super high.

In addition, they have been hiding underground, and they have no connection with it, and it will be a few points more expensive to buy something, and there is no way to store much of those gold mines in the Demon Dragon King.

Looking at this map, Ou Xiaolu and Tie Zhongxiao glanced at each other, "Stay." ”

This underground world is a good place, and although the third layer is now the bottom, it is not sure how long they will have to dig down.

The location of the Demon Dragon King occupies about half of the third layer, Ou Xiaolu checked it, in the territory of the Demon Dragon King, except for the two passages leading to the second layer, there is only one passage that directly descends from the first layer.

As long as these three passages are controlled, and several other roads on the same level are managed, this is an independent kingdom.

Ou Xiaolu is fully capable of controlling this place.

The most important thing is that Ou Xiaolu has the ability to easily travel between the surface and the underground world, and he has already made up his mind to leave a rainbow gate in the secret base of the Demon Dragon King, so that he can easily enter and exit here.

Tie Zhongxiao also agreed to such a plan, and at the same time he also pointed out a few key positions, saying that the defense needs to be strengthened here.

The locations pointed out by Tie Zhongxiao are all strategic places, as long as these places are guarded, the territory of the Demon Dragon King will not be destroyed.

However, Ou Xiaolu didn't think so, the reason why he wanted to occupy the territory of the Demon Dragon King was that on the one hand, he wanted to use this place as his secret base, and on the other hand, there were more monsters here, and he had high experience, so he could come down from time to time to brush a wave.

According to Ou Xiaolu's idea, if you have no experience, you can brush it down, and when you have experience, the avatar can come down and brush it.

If you brush more, those people in the underground world will know whose territory it is, even if there are fewer people here, they won't dare to mess around in Ou Xiaolu's territory.

Tie Zhongxiao didn't know what to say about Ou Xiaolu's thoughts, but he agreed with Ou Xiaolu's efforts.

The Demon Dragon King, who was judged to be the weakest dragon, also stimulated Ou Xiaolu, who was not an invincible existence in the world.

Therefore, it is not too difficult to understand that Ou Xiaolu will have this kind of hard work and self-motivation.

After packing up the things here, Ou Xiaolu followed the map and circled around the territory of the Demon Dragon King.

The base for making and cultivating the Demon Dragon King's dependents is automated, and there are a large number of dragon eggs inside, and it can be seen that the dragon eggs hatched should be the existence of dragonmen or dragon-like people.

This is not what Ou Xiaolu needs, so he doesn't have time to bring a group of dragons to play here.

Ou Xiaolu needs subordinates like Wayne or the former archbishop, who can be taken out to fight, and who can be placed at home to study.

Then Ou Xiaolu went to the Demon Dragon King's splicing laboratory again, and he found that there was nothing related to the laboratory except for the fact that it was called a laboratory.

The whole place looks like a slaughterhouse, with various pieces of meat thrown haphazardly, some of which are stitched together with finger-thick twine.

I don't know where they got their faith so that they could piece the creatures together.

Seeing that such a good underground space was wasted like this, Ou Xiaolu was also a little speechless, and he directly released the [Space: Laboratory] in his hand.

I put the large room laboratory that can accommodate 20 people here.

The moment this space card was released, the entire space changed, and the space that originally looked like a slaughterhouse became clean, surrounded by high-tech backgrounds, and the locations used to place various instruments were also sorted out.

The most important thing is that in the middle of the space, there is a large computer for distributing energy and computing.

Of course, this computer is also a good thing in the eyes of others, only Ou Xiaolu can open it, and there is only one interface inside.

The interface is divided into three lines, the first line is the place where Ou Xiaolu writes the research direction and requirements into it.

The second row is the card line, which requires Ou Xiaolu to put 20 character cards into it, as for the requirements, it is best to be a scientist type of character, if not, then there must be a role to learn and study characteristics.

The third line is the amount of resources invested, which can be experiments, items, gold or energy.

After putting everything in, click enter below, and the 30-day research work will start on its own, and Ou Xiaolu only needs to come back after 30 days to see the results.

As for the direction of research, it is completely up to Ou Xiaolu's own preferences, he can study how to make movies, how to deal with certain ingredients, certain weapons or combat methods, and even martial arts or skills.

With such a change, Ou Xiaolu was thinking in his heart whether he could turn that cultivation base into his own arsenal or something.

It's just that he doesn't have a suitable space card in his hand now, and in the store, the asking price of a better space card is on the high side, and now even if Ou Xiaolu has a five-figure gold coin, he can't afford anything.

Therefore, he can only put his hope on the conquest of the world in the future.

"You said that if you want us to put another miniature world and send three ordinary characters out, it shouldn't affect our plan."

"You can open the world if you want to, but I have to remind you that you don't have a few suitable worlds in your hands, and those worlds have been assigned by you."

"Alright, let's go back to the valley while I deal with the portal."

said that Ou Xiaolu was at the residence of the Demon Dragon King before, and put down the second rainbow door, which was the orange one.
