"Hungry!" A vague thought came to Leo's mind.

Leo was startled, his hand stretched out from the nutrient solution, and looked at the biological metal floating in the nutrient solution, with a look of surprise on his face: "This is from this biological metal!?" ”。

Leo was a little unsure, with a look of hesitation, put his hand into the nutrient solution again, his hand slightly emitted some electricity, and then a happy emotion appeared in Leo's mind, feeling like a puppy that had been fed, exuding pure closeness to Leo.

"That's it!" Leo looked at the black bio-metal, his face was cloudy, although the bio-metal's thinking ability is still very weak, but there is no doubt that this has been out of the category of tools, which makes Leo want to destroy it, but if it is destroyed, Leo is very distressed, after all, this is something he has obtained after studying and experimenting for a long time, with this contradictory mood, Leo fell into thought.

After thinking for a moment, Leo let out a long breath and muttered to himself, "Destroy it and then make it?" What if that's still the case!? ”。

Thinking of this, Leo gritted his teeth and said secretly: "Big deal, when this thing is out of my control, I will destroy it!" ”。

Putting his electric hand into the nutrient solution again, looking at the rapidly proliferating biometal and the increasingly clear thoughts and emotions, Leo carefully observed, until a palm-sized time, the biometal began to roll in the water, and began to unconsciously change its form.

Seeing this, Leo took out the biological metal, and with the mentality of trying, he handed over an idea, and then the biological metal was like jelly, and after two flicks, according to the idea passed by Leo, Leo's hand was wrapped and turned into a black hand armor.

At this moment, Leo's telepathy felt a very weak mind, attachment, happiness, admiration, like a baby who can only express his emotions, pure and immaculate, giving Leo the feeling of a baby meeting his parents.

"You won't think of me as a father!" Leo was stunned for a moment, and then relieved, for this biological metal, wasn't Leo who made it his father's identity?

Leo smiled helplessly, and the electric energy on his body quickly gushed out, and then after the black hand armor absorbed the energy, it spread and increased in value at an extremely fast speed, covering Leo's whole body after a while.

Then the problem arose, because of the increase in biometals, the weak mind could no longer control all the biometals, and in the end, except for one of Leo's arms, which was still covered with biometals, the other biometals actually slid directly down Leo's body to the ground, and then after only a breath of time, he lost the ability to move, as if he was dead, and turned into black fine particles.

"Grievance?" Feeling the emotions coming from the bio-metal consciousness, Leo was stunned, and while feeling amused, he began to think of a solution.

"If you can't control it, it's because it's weak in thinking, so strengthen its thinking power!"

"People's thinking ability becomes stronger with age and knowledge, and for it that can grow up with energy, the concept of age does not exist at all, so you can only try knowledge!"

Thinking of this, Leo began to use the ability of telepathy to slowly contact the weak consciousness of biological metals, and then after the weak consciousness sent an attachment to Leo, Leo began to try to pass on a number in his mind, and at the same time read it repeatedly to this weak consciousness like teaching a baby.

"1" A few minutes later, as Leo continued to teach, the weak consciousness repeated the number Leo had given.

Seeing this, Leo was overjoyed and began his own teaching time, the first number, it took six minutes, and the second number was directly shortened by half, until finally, this consciousness learned faster and faster.

Eventually, after seven days, after this weak mind had grown to a level comparable to that of a five- or six-year-old child, a 'full' mind was issued.

"There's still time to be full!?" Leo smiled.

"Master!" A childish metallic voice sounded in Leo's head with a sense of anticipation.

"Starry Night?"

"It's me!" Biometal heard Leo's words and happily responded.

As the voice fell, Leo felt that there was an invisible connection between him and the creature metal 'Starry Night', they could feel each other's existence, Leo could feel Starry Night's existence, and Starry Night's attachment and admiration for him was beyond his imagination, and even Leo felt that as long as he had a self-destructive thought, this Starry Night would definitely destroy itself without hesitation.

"What a bonus!" Leo laughed happily.

"Warframe Mode!" After this thought flashed in his mind, Starry Night, which tightly covered one of Leo's arms, moved, and in the blink of an eye, it covered Leo's whole body, still a black battle armor, still a black mask that only covered half of his face, but the difference was that it was completely enhanced.

After testing, Leo, who was wearing Starry Night, now has an astonishing strength of one hundred and fifty tons, and his speed has reached an astonishing one and a half times the speed of sound, and now Starry Night's ability to resist the impact has become nearly ten times stronger than before, reaching the level of 100 tons.

Nodding with satisfaction, most of the armor covering Leo's body turned into black powder and fell, leaving only the black armor that was covered with black armor at first, and then the black armor changed to palm-sized black metal again.

"What is this?" Leo was a little puzzled, and Starry Night seemed to sense Leo's doubts, and immediately began to explain to Leo, but Leo listened a little depressed about the process of explanation, but thinking about the level of thinking that was only five or six years old, Leo no longer asked for anything.

Finally, in the midst of that somewhat confusing explanation, Leo understood.

Keeping it the size of a palm, it will have the autonomy to fully control its body and move freely, such as now, the creature metal starry night, has become a palm-sized, uh, black cat!

When it is beyond the size of a palm, it loses its ability to act autonomously and becomes a good helper with thinking skills, such as Leo's armor, or something else. So in order to stay on its own, Starry Night will automatically let those unused, redundant creatures die of metal.

Because Starry Night itself has the ability to absorb energy, when it becomes a Warframe, it can be quickly multiplied with the energy it usually stores, and it can become a Warframe almost in the blink of an eye, but if it is beyond the quality of the Warframe, it will need Leo to provide energy or absorb energy by himself.

The difference between these two energy supply methods is that if Leo provides it, the proliferation rate is completely controlled by Leo, and the more energy Leo provides, the faster the proliferation will be, while the latter absorbs the free energy to proliferate, the proliferation rate will be extremely slow.

Now that the purpose of this 'retreat' has been achieved, there is no need for Leo to stay in the laboratory anymore, so Leo calls out to the starry night, and after the palm-sized black cat climbs onto Leo's shoulder, Leo walks out of the laboratory where he has been staying for forty-three days.
