The evolution of the second knife is somewhat different from Xiaoqing.

It does not promote its own evolution with the advancement of talent, but the evolution that occurs naturally when its own evolution reaches a certain threshold.

Although Du Ya has not seen natural evolution yet, this aspect itself is set by his parallel 'Creation God', and of course he will not be unfamiliar.

Just as the advancement of talent will promote its own evolution, its own evolution can also reverse the advancement of talent, but how it is reversed, this Du Ya is not very clear.

The promotion of the second knife is just right for him to observe.

If you pay attention to it, you will find that the figure of the second knife is also the same as the last time Xiaoqing was promoted, and it is quietly changing.

Its pair of golden twin knives have become much wider than before, and they also look a little sharper than before.

In addition, the golden shell on its body has become tighter, firmly encasing its body inside.

After about ten minutes, this series of changes gradually stopped, and the aura on its body also changed suddenly!

At this time, its breath alone has surpassed Xiaoqing, who has been promoted for a few days!

Although it was promoted some time later than Xiaoqing, it was obvious that Xiaoqing would probably not be its opponent if it was singled out now.

At the same time as it woke up, a hint suddenly appeared in Du Ya's mind:

"Detected that your intimacy with the mutant sword mantis (two knives) has reached 90, the current battle pet binding limit is 3, and the remaining vacant slot is 2, do you bind the mutant sword mantis (two knives) as a war pet?"

"Yes/No"

……

"Sure enough, living and dying together is the best way to get closer to each other." Looking at the prompt in his mind, Du Ya sighed.

The series of hunting operations in the past few days not only increased Xiaoqing's intimacy with him from 90 to 95, but also apparently sharply increased the intimacy between Erdao and him.

Not only that, but even Xiaoqing and Erdao, who were originally not very friendly with each other, have now become closer.

Of course, healthy competition is still inevitable, but at least it won't be as distant as it used to be.

After noticing this before, Du Ya understood that the intimacy with Erdao might not be long before it reached 90, but he didn't expect that this day would be just when he was successfully promoted.

Thinking about it, if he hadn't met Du Ya, it would have been almost impossible for Erdao to hunt a mid-level mutant species alone.

Without these few hunts, naturally there would be no chance to eat mid-level beast meat, and it may take a long time to get promoted.

It was the joy and gratitude brought by the promotion to the middle level, coupled with the battle of life and death, that finally raised the level of intimacy to 90 in one fell swoop.

Du Ya naturally didn't have to think about it, and directly chose 'yes'.

After a while, a layer of light appeared on his and Erdao's bodies, just like the last time Xiaoqing was bound, and he could finally communicate directly with Erdao through his thoughts.

By the way, I also checked the current data of the second knife:

"Name: Mutant Blade Mantis (Second Blade)"

"Age: 1 (3)"

"Intimacy: 90"

"Evolutionary Level: Intermediate"

"Talents:

Spring Lv.2 (0%) - The feet become super spring-like and have unmatched ejection power

Great Power Lv.2 (0%) - Super Strength

Golden Body Lv.2 (48%) - The whole body is as hard as King Kong

Blade Lv.2 (52%) – Dual blades can be as sharp as real knives and have unmatched cutting power."

……

When he saw the data of the second knife, Du Ya was honestly relieved.

In fact, he has always been worried that the second knife will suddenly hang up one day, because the lifespan of ordinary praying mantis usually does not even have a year, and the initial mutation does not increase the lifespan.

Before the second knife was not bound to the war pet, Du Ya couldn't see its age and lifespan, so he naturally had this kind of worry.

In his setting, evolution can indeed extend lifespan, but from which stage it begins, he doesn't know.

Fortunately, he found that after Xiaoqing was promoted to a middle-level mutant species, his lifespan was extended from the original 5 years to 10 years, which made him sure that evolving to the middle level could indeed extend his lifespan.

The original lifespan of the second knife was only 1 year at most, but now it has been directly increased to 3 years, which is more than tripled.

As for the other data, it was not beyond Du Ya's expectations.

The two talents, 'Spring' and 'Great Force', were originally at the Lv.1 level, but because of this promotion, they all advanced to the Lv.2 level.

'Golden Body' and 'Blade' were originally Lv.2-level talents.

But Du Ya's previous intimacy with Erdao was less than 90, and he couldn't see specific data, so he didn't know what the original development degree was, and there was no way to judge whether the development degree was improved because of promotion.

But these are all details, and Du Ya didn't care too much.

"So...... It's my turn—"

Du Ya glanced at the evolution value that had been filled up by the overstepping of the level and hunted four mid-level mutant species, and muttered.

After instructing Hao Xiaoqing and Erdao to help guard the surroundings, the next moment, he directly raised all the Lv.1 level talents to the Lv.2 level at the same time!

Almost at the same time, he felt a warm current appear out of thin air in his body, quickly spreading throughout his body.

This warm current was no stranger to him, and it had also appeared when he advanced his talent.

Only this time it came more violently and more quickly.

With the appearance of this warm current, he felt that his body was slowly transforming, and he could clearly feel that his strength, physique and other basic data were rapidly improving.

This kind of basic data will not be displayed in the data panel, but this is the fundamental gap between mutant species of different ranks, and it is also the reason why it will be difficult to fight by skipping levels.

About twenty minutes later.

Du Ya's transformation gradually stopped.

This also means that he has finally been promoted!

Moreover, his aura after promotion is only stronger than that of the second sword, which shows how much improvement this promotion has bringed.

After the transformation ended, he also checked the data after his promotion for the first time:

"Name: Mutant Raven (Du Ya)"

"Age: 5 (40)"

"Evolutionary Level: Intermediate"

"Talents:

Beak Strike Lv.2 (0%), Feather Arrow Lv.2 (0%)......

Sky Rift Lv.2 (0%) - Both claws have extraordinary tearing power and can attack targets with air blades at short distances

Godspeed Lv.2 (0%) - Extreme flight speed

Dimension 2 (35%) - Possesses extraordinary super visual range and dynamic vision, and can use his gaze to scare and terrify his target, or create a brief illusion to confuse him

Metal Electric Feather Lv.3 (31%) - The feathers all over the body are made of steel, and it has amazing defense and is infused with lightning power, which can greatly reduce energy damage."

[Evolution Value: 162.8]
