The evolution below continued, and eventually the fifth-order appeared, but this frightened the onlookers on the rooftops of several buildings, because the fifth-order mecha beasts began to undergo huge changes, the most obvious being these huge guys, they began to fight more than just relying on their bodies.

That's right, kinetic weapons appeared, they began to mutate from various parts of the body, and finally became guns that could shoot metal bullets, yes, it was the early kind of gun, as for whether it used gunpowder as kinetic energy, Luo Aya didn't know.

But the appearance of this weapon has increased the danger of the mecha beast by more than one level, and even if the claws are sharp, it is impossible to have the initial velocity like a bullet, but fortunately, the guns evolved by these fifth-order mecha beasts are still only single shots, which makes the human race not helpless all of a sudden, but Luo Aya has foreseen that the life of the human survivors in the future will be even more difficult.

The fifth order is already terrifying, but what about the sixth, seventh, or even higher ranks?

Does it mean that there will be more powerful weapons with the birth of ranks?

For these, Luo Aya felt that she would soon be able to see that there were still many mecha beasts in the square, and there were more and more fifth-order ones, and even some mecha beasts began to climb to the sixth order.

The appearance of the fifth order made Luo Aya's eyes condense for a moment, and the battle intent overflowing from the flow of her eyes could even be felt by the subordinate posture next to her, this was Luo Aya's belligerent factor hidden in the depths of her heart, and in her subconscious, she was still a man who stood up to the sky.

Even if her body changes, it can't change the fact that she was a man, many of her concepts are very different from ordinary girls, Luo Aya still likes girls until now, in her cognition, how men and men are together.

The other two survivor gangs were also shocked by the birth of the Fifth Order, they never thought that this world would become so strange, how did these evolving monsters come about? And how did they manage to reproduce human kinetic weapons?

A once-in-a-lifetime opportunity to watch the mecha beast climb to a higher level gave Luo Aya the idea of becoming stronger, Jia Li had the perception that she could not fight against it alone, and made Hattori Jiro see clearly that he had also abandoned his hatred and turned to a more long-term goal.

And other unrelated people, such as Shi Hua, she was very excited at this time, witnessing the birth of the high price of the mecha beast, which made her realize the shallowness of her previous knowledge, it turned out that the world has a broader world, and she also has a richer experimental body.

Although there are no conditions for experimenting now, being able to observe the progress of these strange creatures still makes Shi Hui excited, if she continues to follow Luo Aya, will she be able to see more, or even more peculiar life processes?

From then on, she decided to stay with Luo Aya, unless she felt that what she had observed around Luo Aya was enough, and then she would leave and set up a safe laboratory in which to conduct her crazy experiments.

Noodle, who didn't know what her trusted doctor was up to, could only watch with trepidation at what was happening below, those terrible monsters really scared her too much, and even the new weapons produced by the monsters made her crouch on the ground with her head in her hands.

This also made Shi Hui only shake his head, this assistant nurse is good at everything, but he is too timid to be of great use at all, and I hope that in the more dangerous journey in the future, this little timid guy can become bold.

However, the ongoing evolution below has not stopped, the sixth order was born, but it doesn't seem to have become much more powerful, it only makes the bullet more powerful, and the size has become more huge, it seems that not every advance can get a leap in strength, and the progress of technology can only be crossed at certain stages.

There are fewer mecha beasts in the field, it seems that these numbers are only enough to see the birth of the seventh order, but the sixth-order mecha beasts are already two stories high, this size of monsters, if ordinary humans encounter them, there is absolutely no possibility of escaping, and even Luo Aya is not confident that he can defeat such a behemoth, what will happen to the seventh order?

It didn't take long for the seventh order to be born in the frightened eyes of everyone, the six barrels on the body, which proved the birth of the repeating weapon, and the body size was even higher from two stories high to six stories high, and the buildings in the central city were generally twenty or thirty floors, and this guy was already about to reach one-third of the building.

How can this not be frightening, how big it will be if you continue to advance? This made Luo Aya more and more incomprehensible, what is such a huge size to do? What supports the energy they need for their massive body movements?

"It's so exciting, these monsters actually formed a fusion furnace in their bodies, do you see those transparent cylinders on their backs? That's the coolant that must be used in fusion furnaces, and this monster is powered by the energy produced by nuclear fusion, which is incredible! Humans have only now touched the threshold of fusion, but these guys have already given birth to fusion furnaces in their bodies, which is really powerful! ”

Shi Hui suddenly became extremely excited, after all, she is a scientific worker, even if she is biological, but it does not prevent her from knowing the latest technology of human beings in advance, but Shi Hui's words also let Luo Aya solve her doubts.

It turns out that such a huge body is powered by a fusion furnace, and she probably knows what a fusion furnace is, anyway, human beings have not been able to realize this technology now, and with such a powerful power, how much power can be generated, in fact, Luo Aya is not clear.

After all, there is no other seventh-order that can make the other party fight with all their strength now, and what kind of anti-heaven power the other party has Luo Aya can't judge, but he only knows that if the two seventh-order fight, I'm afraid it will be at the level of earth-shaking mountains, even if they are now on top of a high-rise building, they won't be safe.

Reinforced concrete is actually not as strong as it seems, and the human race, which loves to die, has countless ways to tear down hundreds of floors of skyscrapers, not to mention these monsters powered by nuclear fusion.

The controllable nuclear fusion reactor is used to power a mecha beast that is not even the size of a warship, which is equivalent to installing a perpetual motion machine, and the inexhaustible energy makes Luo Aya a little envious.

"This monster is blocked down now, how are we going to go down?"

Lizi felt that she had a toothache, it was not enough for this thing to cover the entire square, her body had even stepped out of the square, and the most edge of the place was even going to the building where they were, how to leave?

"Only when it leaves on its own, it seems that a mecha beast of this size has lost that strong desire to attack, and it is so quiet now that it shows that this guy is not so eager to continue evolving. It is expected to leave here after a while. ”

Sure enough, Shi Hui was right, this behemoth walked out of the square with steps that could make the building shake after not discovering what caught his eyes, and the outer wall of the building was shattered and fell down, and it didn't even make this huge monster look at it.

The monster was about to leave, but Luo Aya found a terrifying figure, it was a girl in a nurse's outfit, and the conspicuous metal shelves and a row of transparent cylinders behind her proved the identity of this girl, the terrifying woman Luo Aya and Lizi had seen.
