After talking about the underworld, the ghost king of the underworld didn't leave Liu Zong much time to think, and he began to explain his thoughts about his career, whether it was the method of success, or some of his unsuccessful ideas at the beginning.

The traps that may be arranged by the underworld, the requirements that must be met, the goals of growth, etc., are all within the scope of the Ghost King of the Underworld.

Liu Zong didn't listen so carefully at first, but as he listened, Liu Zong's eyes became more and more solemn, and there were too many things that he hadn't thought of, but they were quite important.

Especially regarding the basic research, the Ghost King of the Underworld explained beyond the ordinary level, and Yanagi believed that even if he pulled a Lv1 lord to listen, he could get quite a lot of things from these basic contents.

At the same time, the more Liu Zong listened, the more frightened he became, because he found that there were too many hidden things hidden in the basic knowledge, and if one didn't pay attention, he might jump into someone's trap, and this kind of trap, you can't detect it if you haven't reached a certain level.

After reaching that level, even if you find it, it's useless, and if you don't spit out a little benefit, you won't be able to get out of these traps at all.

All of this was eaten by the Ghost King of the Underworld at a loss, if the Ghost King of the Underworld was still alive, as a person with vested interests, he would definitely not say this.

But now that he's dead, and there's only a little memory left, and most importantly, this part of the memory isn't visible to everyone, so he just made everything clear.

In this way, Liu Zong is much more convenient, at least some obvious traps he no longer stupidly jumped into, and at the same time, Liu Zong also found that there are fewer and fewer routes that he can develop in the future, and there are only a few routes that are obviously incomplete.

Although Liu Zong did not make a choice, these routes have taken root in Liu Zong's mind, if it weren't for Liu Zong's own route that is not quite the same as that of the Ghost King of the Underworld, maybe his future growth will follow this trajectory.

As soon as three weeks passed, the memory of the ghost king of the underworld disappeared directly in front of Liu Zong, Liu Zong shook his head, and threw away some unrealistic ideas, at this time Liu Zong couldn't help but smile, he had been listening to the ghost king of the underworld say how others set traps, but he didn't expect that the biggest trap pit was still the ghost king of the underworld.

If it weren't for the fact that Liu Zong took the route of moving the fortress, and the core part had been fixed, he would really believe what the Ghost King of the Underworld said, and finally embark on the route of the Ghost King of the Underworld.

Now it seems that what Liu Zong has heard in the past three weeks will go back and sort it out to see how many traps there are inside.

But these three weeks have not been in vain, at least for the basic things, Liu Zong knows more, he knows where he is still missing, and at the same time, he also understands, don't think that many of his ideas are brain-blowing, in fact, many things are the routes that others have taken, but they have failed.

As for the reason for the failure, Liu Zong is not clear, but there are examples to be checked, and it can be slowly reversed.

After Liu Zong thought about going back, he would honestly stay in his own territory, and he was not in a hurry to advance to Lv3 or anything, so he laid his foundation first.

At the same time, let's seriously deal with the matter of the Dragon Graveyard, the battleship bone dragon has been done before, but in fact, the product that replaces the undead dragon has no clue.

After Liu Zong went back, he would check the forum to see if there were any masters who had sorted out the previous information and sorted out the products used to replace the undead dragon.

In fact, Liu Zong is not worried about this at all, there are everyone in the Heavenly Emperor Lord University, Liu Zong doesn't have to worry about not finding a suitable method at all, he is only worried that these methods have been monopolized by some players.

Fortunately, Liu Zong's luck is good, he can also afford a lot of money, after asking some players, Liu Zong finally got what he wanted, he selected seven materials and solutions for the Dragon Graveyard to replace the undead dragon, plus the battleship bone dragon that has been systematically formed before, and a variant of the Constant Wing Abyss against the ghost dragon, Liu Zong's dragon graveyard can train a total of nine undead dragons that do not belong to the dragon class.

There are only a considerable number of ghost dragons in the Constant Wing Abyss, and they are named the Broken Sword Ghost Dragons by Liu Zong.

The reason why there is such a strange name is entirely because this ghost dragon is based on an ancient long sword, and there are not too many requirements for the type of sword, as long as the sword body or hilt is engraved with a dragon type, as for whether it is a yin carving or a yang carving, it doesn't matter if it is a relief or a real carving, as long as there is a dragon or a complete dragon.

After that, these longswords engraved with dragons will be placed in the Abyss of Constant Wing, and the dragon patterns on the longsword will be stimulated by the ice water.

This is a very fatal method, because under the stimulation of those ice waters, often the dragon pattern has no spirituality, and the long sword has spirituality first.

In that case, there is no way to transform this sword into a ghost dragon, and it can only be sent out to be used as a high-end weapon.

So after such a long time, there are only five ghost dragons under Liu Zong's command who can break the sword and become a broken sword ghost dragon.

They have a natural ability to fly swords, and they also have the ability of ghost dragons, and they can also turn into long swords for human use when necessary, which can be regarded as a super combat class.

If it weren't for the fact that it was not easy to make, Liu Zong would definitely make a large number of Broken Sword Ghost Dragons to expand his troops at the first time, how could it be like now, there are only five Broken Sword Ghost Dragons in total.

Of course, the undead dragon experimented by Liu Zong is not comparable to the existence of countless people's brains, and among the seven selected by Liu Zong, all of them are like this.

For example, the countless wine dragons stored in the dragon-shaped flask, the tree dragons that grow from trees into dragons, and so on, are all existences that can be used to replace the real dragon.

And these existences can also be transformed into undead dragons, among the seven types selected by Liu Zong, the least number and the most difficult to find are the dead dragon veins, which can automatically generate dragon spirits, and even fewer die after generating dragon spirits, and most of them will be sent to the Underworld Sea at the moment of death, and there are even fewer that can be caught by necromancers.

But Liu Zong would never give up such an undead dragon, because he knew how powerful the dragon vein was, and the strength of the undead dragon transformed from the dragon vein would not be weakened at all because of the death of the dragon vein dragon spirit.

Therefore, when Liu Zong saw the production method of this undead dragon, he decided that even if he didn't have a dragon vein dragon spirit under his hand, he had to master the production method of this undead dragon to ensure that he would not waste the best opportunity in vain if he encountered it.
