"You're doing a great job." Stopping Liu Zong from continuing to ask, the man said casually, "We don't owe each other in the future, by the way, if I were you, stay here for a while, your world is not safe for the time being." ”

After saying that, the man stood up and prepared to leave this position, about two steps, the man seemed to think of something, he turned his head and said to Liu Zong: "This city may be of some use to you, see for yourself, what can you find here." ”

Liu Zong was a little surprised, "What about the Yellow Spring Dragon King? ”

"That little guy won't come back, it's useless to stay here, how much you can find from here is up to you."

After speaking, the man disappeared in front of Liu Zong like a bubble, and at the same time, the red light of the heart disappeared.

Looking at the heart space that belonged to the Huangquan Dragon King City in front of him, Liu Zong's eyes lit up, just as the man said, this city that originally belonged to the Huangquan Dragon King was too useful to him, and what Liu Zong could go in the future depended on how many things he could get here this time.

After making sure that the man had really left, Liu Zong turned his head to look at the Underworld Floating Dragon coiled in his hand, and with a slight lift of his hand, a black mist spread out around with the Underworld Floating Dragon as the center.

The black mist did not spread quickly, and at the same time, Liu Zong also broke away from the Floating Dragon of the Underworld, heading deeper into the dragon's bones.

Unexpectedly, just like this, Liu Zong was attracted by the things left by the Huangquan Dragon King, I have to say that everything that the Huangquan Dragon King has is in line with Liu Zong's appetite, and many things are originally considered by Liu Zong, but there is no place to study.

Now there is such a large experimental field, even if it is basically destroyed, it still deeply attracts Liu Zong, and Liu Zong has been here for a hundred years.

In the past hundred years, Liu Zong only took about a year to go through the entire dragon bones, and then he immersed himself in studying what was left behind by the dragon bones, but it took him a full fifty years.

After that, Liu Zong spent another fifty years transferring all of this to his Canglong Fortress.

And this hundred years for the Canglong Fortress, has not stopped, although the major changes are basically carried out in the last fifty years, but the Canglong Fortress itself has begun to grow in the first fifty years.

At first, Canglong Fortress would go to the vicinity to find some undead to absorb and devour, but ten years later, after Liu Zong began to formally study, Canglong Fortress began to transfer some of the things on the dragon bones to itself.

Although it was developed from the side of the Huangquan Dragon King, there are still some differences between the Canglong Fortress and the city of the Huangquan Dragon King, and it can be seen that the Huangquan Dragon King has put the entire city on his own dragon, and the city has many different roles on the dragon, and it looks like many satellite cities.

Liu Zong is different, Liu Zong's satellite cities have been divided, and he doesn't plan to take these cities back, so the things obtained from the dragon bones of the Huangquan Dragon King have been classified and placed in the Seven Acropolis and the Five Domain Cities.

Even so, the size of Canglong Fortress has obviously become much larger, and the entire Canglong Fortress has become seven times the size of the original Canglong Fortress, and its body size has completely exceeded the limit of the Lv3 level Canglong Fortress.

The most important thing is that Liu Zong learned the management method of the dragon, began to adjust the situation inside the Canglong Fortress, and began to distribute the buildings inside the Canglong Fortress to the city.

At the same time, the location of the head of the Canglong dragon of Liu Zong has also changed a lot, at least Liu Zong no longer only uses the head of the Canglong Fortress as a bridge for the main base, but learns to use this place as a huge city like a giant dragon corpse.

Because of this, after more than a hundred years, Canglong Fortress has become a little less like what it was before Liu Zong.

In fact, Liu Zong planned to delay it for a while longer, he felt that there were still too many things on the bones of the dragon that he hadn't studied clearly.

But Liu Zong finally had to forcibly interrupt his research work, because he found that if he continued like this, he would really embark on the path of the Huangquan Dragon King.

This was something that Liu Zong once felt while studying the core technique of the dragon corpse bone, and suddenly something suddenly appeared in his memory, and these things seemed to be slowly affecting his habits.

For example, Liu Zong has always used martial arts for the Seven Kills of the Underworld, but during this time, Liu Zong has forgotten to practice the Seven Kills of the Underworld, and has also forgotten to study the magic that matches the seven moves under the [Hell Sea].

This situation is a little wrong, more than a hundred years ago in the cross-star map, Liu Zong was able to find time to conduct research, there is no reason for him to give up these studies when he reaches the underworld.

This situation made Liu Zong can't help but be vigilant, he has not forgotten where he started from, nor has he forgotten the influence that the Huangquan Dragon King has brought to him.

If it was somewhere else, Liu Zong believed that he could press down the soul fragment of the Huangquan Dragon King, but it was different here, this was the burial place of the Huangquan Dragon King, in case he had any backhand.

Liu Zong, who wanted to understand this, simply wrote down what he hadn't understood yet, took the Canglong Fortress, and prepared to go up the River Styx back to the real world.

This time it's much simpler than last time, Canglong Fortress's current individuals, combat power and everything have exceeded the level of Lv5 or above, even if someone in the underworld is eyeing Liu Zong, he can easily escape.

In addition, Liu Zong's own strength has also improved a lot, and at the same time, his understanding of the underworld has also strengthened a lot, so he has gone quite smoothly along the way.

Liu Zong did not enter the hostile sphere of influence in the game world at all, but went around through various ghost gates or portals, trying to find a way not to pass through the territory of various big forces, and did not intend to pass directly from the real world.

Fortunately, for the underworld, the division of the real world is not the same as the division within the underworld, and various ghost gates can connect the entire underworld.

It can be said that the entire underworld is like countless fragments, and Yanagi just chose to skip some places that seemed dangerous, and followed a safe route to find his way home.

In this way, Liu Zong himself was safe, but his speed of going back was much slower, and it took about ten years or so in the underworld for about ten years, and Liu Zong finally returned to the underworld that belonged to the game world.

After entering here, Liu Zong was directly discovered by the Grim Reaper in the game world, and a Grim Reaper who seemed to be super powerful appeared directly in front of Liu Zong, and asked with some hesitation: "Where have you been for more than 100 years?" ”
