After pondering for a while, Roland decided to put aside the physical attributes first, and there was another change - pure energy.

Regarding the existence of pure energy, like the physical attributes, Roland has known for a long time, but the system has not explained in detail.

After guessing for so long, he was finally able to see the explanation from the "official", and Roland hurriedly checked it.

First of all, in terms of sources, there is no change from before, it is still a transformation.

That is, the undesirable products that have been parsed, or the objects that cannot be analyzed, are converted into pure energy.

After so many days of trying, Roland has long discovered that the skill of [Predator Transformation] is not exactly an "active skill", at least the system almost never asks whether he uses it.

In particular, the prompt of the system just now is "enough energy has been obtained", which must be that it directly uses the transformation ability to convert those undesirable products after analysis into pure energy.

The system seems to have its own consciousness, always doing something on its own, and there is no system prompt, which makes Roland a little wary of this system.

However, Roland couldn't imagine that such a powerful system would plot anything against him, and he really needed to use it to become stronger, so he simply buried this vigilant thought in his heart and continued to look down.

What follows is the use of this energy, which is much more extensive than Roland imagined.

The first point is naturally for system upgrades, which is the so-called functional optimization, which is clearly written on it, and the second stage of optimization requires 10,000 points.

Roland looked at the lone 6 on the panel, and he didn't know what to say, and the system wanted to do something again?

After scolding a few words in his heart, he looked at the second purpose—upgrading skills.

This made Roland's mood a lot better, although he knew with his feet that the skills that could be upgraded must be limited, but at least this provided a way for himself to become stronger, even if he couldn't prey on powerful creatures, he could become stronger!

Following the prompts in the text, Roland went back to the previous interface to take a closer look, and sure enough, he didn't notice just now that there was a small upward arrow behind some skills.

The feeling of playing the game came to his face, but Roland didn't bother to complain, he clicked on the small arrow behind the additional skill [Swordsmanship: Elementary].

"Upgrading requires 1000 pure energy, insufficient energy, and the upgrade fails."

"I'll go! So expensive! Roland couldn't help but exclaim, paused, and said to himself, "The beginner swordsmanship is so awesome, if you are promoted to the intermediate level, it is normal to be a little more expensive, let's take a look at the others first." ”

As he spoke, he clicked on the small arrow behind the additional skill [Waterjet Cutting].

"Upgrading requires 2000 pure energy, insufficient energy, and the upgrade fails."

“？？？” Roland was stunned, "I don't believe in this evil yet, come again!" Intrinsic Skill [Physical Attack Resistance]. ”

"Upgrades require 3000 Pure Energy ......"

Roland looked at the number behind the pure energy on the interface again, it was not 6000, it was not 600, it was not 60, it was a lonely 6!

What the hell is this girl's upgrade skills more expensive than the other?!

He is really confused, if the system has a heart, it must be black! The kind of black that shines jet-black!

After that, Roland continued to try, and tried all the skills that could be upgraded, but none of them were successfully upgraded......

Among them, the least is 100, and there is more than one, but these skills are all [Upright Walking] and [Direction Sensing], and Roland can't think of how to upgrade and what is the meaning of upgrading.

And the most, which is also very spiritual, only needs 10,000 points! It's the same as functional optimization! What a coincidence!

Roland began to wonder, is this system really optimized? You can't be playing with yourself, right?

By the way, this spiritual skill is an inherent skill [Auto-Regeneration].

After taking a deep breath and calming down, Roland clicked on the small mark again, and the introduction inside was not finished.

The third function is to strengthen the physical attributes, and one hundred points of energy correspond to one attribute...... Well, this feature can also be ignored.

The fourth function is to repair the body, that is, the self-rescue method when suffering damage that cannot be recovered by [Auto Regeneration], and this function does not indicate how many energy points it will cost.

However, with his 9999 defense, Roland believes that as long as he does not die, the possibility of using this function is not high.

Fifth ......

There are also a few functions in the back that are also almost useless, and Roland has skipped them after a casual look.

And the introduction of the new features has come to an end.

Roland closed the system interface, and his mind returned to the real world, still sitting on the railing, facing the sea.

Although it seems to have been pitted by the system, the sky is still so clean, the sea is still so vast, and the sea breeze is still refreshing, Roland's mood can't help but calm down.

Looking behind him, Vaji was not fishing, but was holding a large pile of food, eating deliciously.

Merlin wasn't training either, but leaned against the railing in her newly bought clothes, looking at the sea in a daze.

Roland sensed the magnetic field, there was still a long distance from the target island, there was no need to prepare for landing on the island, the course was normal, and he did not deviate because he was studying the system.

If you have troubles, you need to relax, and in this world without the Internet, isn't playing with your partner the best way to relax?

Thinking of this, he slowly got up and walked towards Merlin and Vaji.

Hearing the movement, Waji's gaze shifted from the food in his hand to Roland, and Merlin also turned to look at Roland.

Then, they heard Roland's slightly laughing voice—

"Will you two fight the landlord?"
