Compared to Leo's surprise, Zefa was also surprised.

"What? Didn't you know the life essence of the Sea King before? ”

Leo smiled bitterly, he was just an ordinary person, and he didn't have any strong guidance, where did he know what sea king-like life essence was.

So, Leo shook his head helplessly.

"That's really surprising to me, you actually let your body transform to this extent without using the Sea King essence?"

Soon, Zefa gave Leo Kop.

The life essence of the Sea King is naturally extracted from the Sea King, but this method of refining is only available to the Celestial Dragons.

Even the navy doesn't have this ability, so all the life essences of the Sea Kings are controlled by the Celestial Dragons.

"Of course, there are also some private researchers who can develop something similar to this life essence, but the side effects are too great, and the life essence produced by the Tianlong people has been tested for eight hundred years."

Zefa continued.

"Only those peak powerhouses know about this kind of thing, even if many people later knew about the existence of the life essence because of the pirates, but unfortunately the Tianlong people have a very tight control over this, and only a part of it is outflowing, so they have been controlling the number, and they have also controlled the number of peak powerhouses!"

Leo couldn't help but ask, "This thing is precious?" ”

Zefa chuckled: "Don't talk about the production method, I gave you two life essences just now, and a hundred-meter sea king can only refine ten to twenty!" ”

Leo secretly said to himself, so he ate a ten-meter sea king just now?

"Don't think about it, this thing is precious but not as powerful as you think! The life essence can only play its greatest role when the body is exhausted, allowing the body to break through the limit, and at other times, at most it can replenish a little physical strength, and the effect is even inferior to the meat of the sea king. ”

Leo nodded, if it weren't for this kind of restriction, the life essence would be too invincible, and eating one would quickly restore his strength, wouldn't this be equivalent to swallowing a blood vial if he fought.

"Compared to this incident, I'm more curious about the fact that you've never eaten the essence of life? Did you just rely on eating, drinking, and exercising to improve your body to this level? ”

Leo nodded, no wonder he felt that his progress was getting slower and slower in the past two months, and the improvement in physical fitness was almost non-existent, and he even felt that he could not become a powerhouse of the level of the three major generals, it turned out that his way of opening was wrong.

"Hahaha, amazing!" Zefa laughed. "I really underestimate you, if you have never eaten the life essence, it means that your progress will be very fast in the next few months, and you will even break through the life level continuously!"

"Life level?" Leo asked.

"Yes, we divide the life level into ten levels, in terms of normal human beings, level six is the limit, and you are now at the fifth level of water, which is already quite high!" Zefa said. "If you want to break through the sixth level and improve your life level, you must ingest a more advanced sea king life essence, for example, the small sea king life essence I just gave you is enough to meet your current needs!"

It turns out that the division of sea kings is not only about body size, but also about life levels.

Generally speaking, for sea kings, the larger the body size, the higher the life level.

However, this division is obviously incorrect, otherwise there will be a very contradictory question: the child of the super-large sea king class is very small, so is this child super large or small?

For the life level, it is super large, and the difference is whether it becomes a hundred life essences or one life essence.

"And for us human beings, breakthroughs in the level of life often make the body taller, so sometimes the body type can also indirectly indicate a person's life level, although it may not be correct, but it can be used as a reference!"

Zefa gave Leo a lot of popular science, including the benefit of joining the elite camp, that is, a large supply of life essence for small and medium-sized sea kings, which was enough to increase Leo's life level by two levels, thus bringing a huge breakthrough in strength.

As for the large and super-large Sea King life essences, they require combat merit and merit in exchange.

To understand it in Leo's way, that is, the elite camp has enough resources, in addition to the life essence, there is also a variety of experience guidance, including but not limited to swordsmanship books, domineering, six styles, and so on.

"If that's all, our navy won't be enough to dominate the sea!" Zefa's statement is very straightforward, dominating the sea.

"In our navy, aside from the above conditions, our navy still has something at the bottom of the box, as for whether you can get it, it's up to you!" Zefa suddenly sold a pass, which drove Leo crazy.

"Don't think about it!" Zefa shook his head. "The navy is an organization, naturally there must be something to attract the strong, otherwise why should others join the navy, it is not enough to just shout for justice, those strong people who are used to seeing blood and blood, how can they be deceived by two words!"

"What does Mr. Zefa mean that I am qualified to know when I become an admiral?"

Zefa nodded: "As long as you become a general, you will be able to get a chance, whether you can quickly step into the general level, it depends on this opportunity!" ”

Leo's pupils shrank, so that's the case!

Next, Zefa told Leo and Green Bull about the training plan.

This training plan is completely different from the average person's understanding of doing push-ups and how much distance to run.

In fact, Zefa didn't care how Leo exercised, whether it was running or lifting weights, Zefa didn't care.

"What I'm going to tell you is that your current ability is enough to exhaust your physical strength in one hundred and thirty-four minutes, so all you have to do is do this, I don't care how to do it, it's your business! And when you run out of energy, you take two small life essences, rest for about thirty-seven minutes, and then keep exercising! ”

Zefa's statement is very simple, his requirement is to grow up in "prostration" and "recovery" that are in line with physical strength again and again.

"My requirement is to do this cycle at least once a day, and if you want to grow faster, you can do it a few more times, according to my estimation your limit is six times, if you exceed six times, the body will be permanently damaged!"

Six times!

Leo chewed carefully, a cycle was about one hundred and seventy-one minutes, let's say three hours, that is, he could exercise eighteen hours a day and then sleep for six hours.

"Of course, the effect of the six-time cycle is not six times that of one time, in fact, it is only three times at most, so how to efficiently increase the strength still depends on your arrangement! I'm only responsible for making your life level breakthrough as soon as possible, understand? ”

Leo nodded, this is enough, what is more important than the level of life.

If he has a body like Zefa, even if ordinary people cut him frantically, it's useless, the vitality of Whitebeard is still vivid, what kind of attack you want, as long as you can't kill him, you are invincible.

"Let's do it first, when you've broken through the two timelines I said, you can come to me, and I'll make a new workout plan for you!"
