"Disaster-level blood in the Abyss? Of the seventy-two demon gods back then, twenty-one had disaster-level blood, but only four are still alive now... You're not planning to take advantage of them, are you? Although the Kang-level blood is theoretically stronger than the disaster-level blood, without the refining plane, the absolute power difference is too great..." Old Man Tan looked at Guan Liyuan strangely.

"Of course not! I just want to ask if there are any of them who are similar to my black demons, so that I can refer to them. The number of disaster-level blood in the Abyss is really more than I thought... But why are the losses so severe now? Didn't half of the seventy-two demon gods survive?" Guan Liyuan said.

"Disaster-level is indeed rare, but... The Lord of the Abyss was also one of the top masters at the time, and was able to rank in the top ten in the Qiankun World. And because they had to "fall" into the Abyss creatures to join the Lord of the Abyss, the number of disaster-level under the Lord of the Abyss is actually the least among all the top masters." Old Man Tan said.

Guan Liyuan also realized that although the disaster level is rare, the Lord of the Abyss is even more "rare"!

"As for why the demons with disaster-level bloodline suffered the most losses... Actually, to be precise, the stronger the demons were at that time, the more they were targeted. Although the disaster-level bloodline cannot become a true master, it is indeed unique in terms of cultivation, and most of them are ranked at the top." Old Man Tan said.

"So the reason why you are fine is because..."

Old Man Tan glared at him unhappily, and then said: "As for the cultivation method of referring to the disaster-level bloodline, you'd better not think about it! Instead of wasting time... it's better to think about how to upgrade your Medusa bloodline."

At this time, Old Man Tan only knew about "Medusa", and didn't know that Guan Liyuan already had the second high-level rune "Self".

"Why is it a waste of time? Even if you can't refine the plane, if you can raise the demon to the rule level..."

Guan Liyuan was interrupted by Old Man Tan halfway through his words: "Wait, if you don't refine the plane, how can you raise the demon to the rule level?"

"Realm! Isn't it said that power and realm are separate?" Guan Liyuan said as a matter of course.

"Where did you hear that?"

"Novel..."

Old Man Tan looked at an illiterate with an expression Guan Liyuan often saw, but now Guan Liyuan felt that he was not illiterate... You have a lot of experience? Have you seen two kinds of high-level runes?

"It seems that you don't have any concept of 'refining the plane'... Do you think that the so-called 'rules', as long as you understand them, are equivalent to mastering them?" Old Man Tan smacked his lips and said.

"Isn't it?" Guan Liyuan asked in confusion.

"Do you know how to calculate the gravity of the plane?" Old Man Tan suddenly asked.

"This..." Guan Liyuan searched for the answer in the forum and then began to recite the formula.

"Well, you can calculate... but do these formulas bring you any power, or enable you to control gravity?" Old Man Tan's question stumped Guan Liyuan.

"Is it because... my understanding is too superficial and I don't really understand it?" Guan Liyuan asked back.

"There is this reason. It is true that memorizing formulas does not count as understanding, but in fact... after you fully understand it, it is still different from mastering the rules." Old Man Tan said.

"Then what counts as mastering the rules?" Guan Liyuan also understood what Old Man Tan meant at this time.

If he does not reach the level of mastering the rules, even if the "demon" is promoted to the world realm, it will only have a limited impact on Guan Liyuan.

"Really mastering the rules is different from the previous minor fights with the environment and domain. You can't master the rules by force by your own strength.

In addition to understanding the rules, you also need to use the essence of the rules to truly master them! And refining the plane will bring the "power of the plane" and "essence of rules" to the saints. The former is to bless the saints with the power of the plane, and the latter is to help the saints master the rules..."

According to the explanation of Old Man Tan, Guan Liyuan understood that "the power of the plane" is like an additional equipment. Whoever refines it will belong to it. After the plane is captured or deprived, the blessing of "the power of the plane" will gradually lose its effect.

In contrast, "the essence of rules" is like signing in wages. It is a kind of rule-oriented existence that is constantly generated in the main world. It cannot be seen, touched, or used to hit people, but it can make the saints hedge against the world rules and help master the rules. Without "essence of rules", no matter how high the achievements in theory are, they cannot master the rules!

The understanding of rules is like knowing "which direction the store door opens" so that you can spend your salary. The more you understand, the more you learn to "compare prices" and "bargain", so you can buy more things faster...

But unlike wages, this thing cannot be saved and can only be "moonlight". If you can't find the store door or the cabinet, you can only "burn" the money.

But even if the plane you refine is captured or deprived, it is just like being fired, and the things you bought with the previous "salary" will not disappear.

The reason why the disaster-level and high-level bloodlines can compete with weaker saints without refining the plane is that the bloodline itself carries the corresponding rules. As long as you grow to the limit of the bloodline, you can naturally master these rules.

It's like inheriting a legacy... But if you want to buy more things, you still need a salary.

The pitfall of the high-level is that he inherited a large legacy, but his wealth is zero, so he can't buy more things at all. The disaster-level just can't start a business by himself, but he can work for others or start a business under someone else's name.

"That is to say... if my 'demon' wants to make further progress in mastering the rules, he must also break through the disaster level?" Guan Liyuan understood.

Old Man Tan stared at Guan Liyuan in amazement, as if to say "Why are you so imaginative?"...

Shouldn't we consider how to bypass the restrictions of the Kang level and refine the plane at this time? What the hell is "also breaking through the disaster level"? Can that thing be upgraded whenever you want?

Marcia was also unlucky that year, which triggered the bloodline promotion, okay?

It's like when you feel that your home is missing a refrigerator, a normal person's idea is to make money to buy one, but Guan Liyuan is now thinking about where to inherit another one to break through the upper limit and improve the lower limit. The difference in thinking!

"Speaking of Kang-level blood and disaster-level blood, what is the level of rules that can be mastered from the blood?" Guan Liyuan asked.

“If a disaster-level person relies solely on talent, his level would be about the same as that of a saint who is granted an ordinary plane. However, after accepting the fief, the disaster-level person’s grasp of the rules can be further improved with the help of the essence of the rules. Take Marcia, your successor… She conquered more than a dozen planes on her own. Her comprehension of the rules is definitely top-notch among the disaster-level people, otherwise her bloodline promotion would not have been triggered.

For most veteran disaster-level people, if they join a powerful master, it is normal for them to be granted about ten planes.” Old Man Tan said.

There is no absolute connection between the degree of mastery of the rules and the number of fiefs obtained, but just like the relationship between "ability" and "salary", there may be other factors such as luck and nepotism, but the two are definitely linked, so it is not wrong for Old Man Tan to use the number of fiefdoms as an example.

Compared with ordinary old-brand disaster-level, Marcia's number of fiefdoms seems to be not much different, but Marcia's plane was conquered by herself, and... the fiefdom agreement she signed with the Lord of Hundred Monsters is 70% and 30% respectively. If you surrender to a powerful master, 50% is extremely generous, 30% and 70% is the mainstream, and the worst is 19%.

"What about the Kang level?" Guan Liyuan asked expectantly.

"Kang level? Kang level can only rely on talent, there is no room for improvement. After mastering the talent, it is about the same as the ordinary old-brand disaster level, or even slightly stronger? But this only refers to the mastery of the rules. In fact... you know." Old Man Tan rolled his eyes.

That's right, Guan Liyuan did understand, but he was still a little depressed. It turned out that the Kang level could only reach the ceiling of the disaster level without any effort, and there was no chance even if he wanted to work hard...

In fact, if they really fought, the Kang level was definitely not an opponent compared to the ordinary saints who refined a plane, because there was still the "power of the plane". The absolute power was too different, so they could only bully the lowest level saints.

Just like Marcia at the beginning, after the bloodline was promoted, the degree of mastery of the rules did not change, but gradually lost the blessing of the "power of the plane", and was eventually surrounded and killed by the former enemies...
