A hot breath began to surge from Zhang Xiaoyu's heart, and then spread along the blood vessels and spread to the whole body, making his whole body boil, both painful and excited.

"Is this what it feels like to upgrade?" Zhang Xiaoyu trembled all over, feeling the feeling that there was power flowing all over his body.

This feeling is not as uncomfortable as expected, but it also carries a certain pleasure.

However, this pleasure didn't last long, it disappeared, and was replaced by a force that burst out from the depths of the internal organs, impacting Zhang Xiaoyu's body, like an invisible claw tearing apart his body, making him can't help but scream out "ah".

Fortunately, this feeling only lasted for a minute or so, and then quickly disappeared, and if it had been another thirty seconds, his body might have exploded, and then splashed the flesh of the landing space.

After the upgrade was completed, Zhang Xiaoyu's body seemed to be emptied in an instant, and then he collapsed, lying on the ground, breathing rapidly.

Now, he needed time to digest the side effects of the upgrade.

Fortunately, he chose to upgrade in the landing space, this is a quiet space for him, if he upgrades in the script and is caught by the boss, then he will be miserable, and if in the real world, he yelled like that just now, he will definitely be discovered by others, and the result can be imagined, he will be treated as a psychopath, and then sent him to the abnormal human research center.

After about half an hour, Zhang Xiaoyu finally recovered, he stood up and patted his buttocks, but found that the wound on his thigh that was drilled out by an electric drill had disappeared, and even the scar was gone. Not only the wound on his thigh, but also all the wounds on his body that were tied with wire, and the wound on his toe that had been bitten by a rat the day before yesterday, were all healed as if they were not injured.

Zhang Xiaoyu couldn't help but be happy, it seems that although there will be some pain in the upgrade process, however, this pain is beneficial, and the healing of the wounds on his body is only one of the benefits.

At this time, looking at Zhang Xiaoyu's personal attribute information, there has been a very big change.

Personal attributes:

Name: Zhang Xiaoyu

Race: Human

Gender: Male

Age: 21

Creature Level: Level 2 [2/9]

Survival Value: 200/200

Stamina: 200/200

Brawn: 9.5/20 [Strength 10/20, Dexterity 10/20, Balance 9/20, Strike Resistance 9/20]

Intelligence: 9.75/20 [Learning Ability 10/20, Memory 10/20, Logical Thinking 10/20, Creativity 9/20]

General Skills: 9/20 [Combat 10/20, Shooting 10/20, Equipment 7/20, Scout 8/20, Medical 10/20]

Special Skills: 2/20 [Attribute Scan 2/20, Self-Healing Ability 2/20]

Personal charisma: 7.25/20 [Appearance 8/20, Aura 7/20, Eloquence 6/20, Personality 8/20]

Evolutionary Composite Index: [8.075/18]

Evolution Point: [0]

XP: [70]

Note: [Level 2 Human Composite Index Calculation Method: 30% Force, 10% Intelligence, 20% Perception, 25% General Skills, 15% Special Skills]

[After the "Evolution Composite Index" is full, you can upgrade your biological evolution]

Except for "special skills", the average index of each attribute point of ordinary adult males is 8.] Ordinary adult males have no "special skills"]

[The initial value of normal human evolution points is 0]

[If you accumulate enough ten evolution points, you can convert them into attribute points at a ratio of 10 to 1, which can be blessed to any attribute item]

[When you kill a certain creature, the evolution points obtained are: the evolution points owned by the creature + 10% of the creature's survival value]

[The experience points obtained can be added to each branch attribute of "General Skill" or "Special Skill" in a ratio of 100 to 1]

First of all, the most obvious change is the health value and physical fitness value, both of which have been increased from 100 to 200, this change, although it did not directly make Zhang Xiaoyu stronger, but, if he encounters a boss stronger than him, the situation is critical, and he needs to escape, then his physical fitness value can play a role, originally he could only run two thousand meters, but now with this physical value, he can run four thousand meters, and, if he is really abused by the boss, then he has 400 health points, the blood is relatively thick, and he will not die so fast... … Well, that's not the point......

The point is that the upper limit of the value of each attribute has been increased, and the upper limit of each attribute has changed from the original 10 to 20, that is to say, the growth space has become wider, the talent has become higher, and each of his attributes has a higher room for improvement, so that he can also make himself stronger by increasing the value of various attributes, of course, this must be based on being able to obtain enough evolution points.

Obviously, after being promoted to level 2, you can use the blessing of evolution points to improve the ability of "special skills", making his special skills more powerful, for example, before he used the attribute scanning function to sweep the "special skills" of creatures above level 2, and now, as long as he raises the special skill of "attribute scanning" to a certain height, he should be able to identify other people's "special skills". In addition, after level 2, the value of special skills has become 2, and there is no need to bless evolution points, so you can get a small increase.

In addition, the calculation of the "Evolutionary Composite Index" has changed significantly. Before, when he was a level 1 human, the calculation of the "Evolutionary Composite Index" accounted for 30% of force, 20% of intelligence, 20% of perception, 25% of general skills plus special skills, and 5% of personal charm, but now, force still accounts for 30%, perception still accounts for 20%, but intelligence is reduced to only 10%, general skills become 25%, and special skills account for 15%, and personal charm is excluded from the calculation.

From the change in the calculation method of this evolutionary composite index, it can be seen that if a level 2 human wants to upgrade, he must pay attention to the improvement of the three attribute values of force, perception and general skills, because these three items account for a large proportion, adding up to 75%.

In addition, the proportion of intelligence has been reduced, and personal charm is not even counted, Zhang Xiaoyu speculated that the calculation of the evolutionary comprehensive index should change with the upgrade, and the proportion of intelligence may become lower and lower, and even completely ignored like "personal charm".

This is actually very normal, just imagine, if there is no upper limit to the improvement of intelligence, the player will keep brushing intelligence, brush to the table, then, isn't there a person in the world who is smarter than Einstein? This is obviously impossible, even if the setting of this "nightmare paradise" allows, in reality, it is impossible.

Therefore, it is reasonable that the calculation of the "evolutionary composite index" will gradually reduce the proportion of intelligence.

The reason why personal charm is not counted is because creatures above level 2 have become insignificant.

Zhang Xiaoyu also speculated that if he upgrades in the future, on his attribute page, the item of "personal charm" may disappear, and the attribute item of "intelligence", as the level gradually increases, I am afraid that he will also suffer the same fate.

Because, if an attribute item is not included in the calculation of the evolutionary composite index, then this attribute item is actually useless. Things that are useless will only occupy a place in the column of "personal attributes". Culling is also a matter of course.

In this way, while the level is still relatively low, the two attributes of "intelligence" and "personal charm" should be brushed to the full level as much as possible. After all, both of these are very practical, especially in the real world. And Zhang Xiaoyu, only when he sleeps and dreams, he will be in the "Nightmare Paradise", and the rest of the time is in the real world. He had to think not only about himself in the nightmare paradise, but also about himself in reality.

Thinking about this like this, Zhang Xiaoyu muttered to himself: "It seems that you can't be lazy in the future, you have to fight monsters to earn evolution points, and if you want to raise all the attributes of intelligence and personal charm to 20, it's not easy......"

Well, it has risen to 20...... This is a bit greedy, you know, the evolution points in Nightmare Paradise are not so easy to earn.

However, he is a perfectionist and since there is an opportunity to improve his intelligence and charisma, he will not let go of this opportunity......
