The moment Fang Yu pushed open the second red door, the stereotypical and neutral prompt sound came to his ears:

"Extreme multi-control—"

He looked up, and in the darkness it seemed that the space was extremely wide, as if he was in a hall, but in a moment's moment, the door had quietly slipped away from his hand and closed automatically. At this time, a red light lit up in the darkness in the distance, dazzling, and before Fang Yu could react, the red light had already slashed into his face.

He had only come to his senses, but as an alchemist, it was almost too late to dodge.

It's just that at this moment, the lizard-people's ritual 'Whisper of the Stars' has automatically taken effect, and the system has made him unconsciously flash to the side under the control of 'Intuitive Evasion', but the 'Forced Evasion' also makes the light blue evasion value instantly reset to zero, and the balance value drops to the red alert threshold at the same time.

Since he didn't react himself, he subconsciously fell backwards, but fortunately, the balance value was still retained, so he rolled a few laps after he fell to the ground, letting go of the opponent's attack. The red light brushed past him, leaving a dark red spot on the smooth ground.

The high-temperature spot dissipates quickly.

And Fang Yu got up from the ground with a little disgrace, and finally saw clearly what was attacking him.

It was a black-haired goblin he had never seen before, covered in mysterious patterns.

But Fang Yu didn't know if it was really a 'clockwork elf', because he had never seen a flexible structure like this - it was not only pitch black throughout, but also irregular spherical, with a prismatic protrusion on all four sides, and the edges shimmered with a metallic cold light.

In the center of the sphere is a rather cold observation device, like a beryl or a dark hexagonal crystal, with a faint red light shining under the dark crystal. The red light was like metal melted at extremely high temperatures, and it was gradually cooling, but the residual heat remained.

There is no doubt that the previous beam of high-temperature red light was emitted by this device.

What is this?

Aside from the Fire Djinn, Fang Yu had never heard of a clockwork elf with an attack before. In fact, due to the small internal space and the inefficiency of most of the cooling devices in this world, most of the attack Direction Wizard devices cannot be mounted on the Clockwork Elf.

Many ways were thought of for this, but in the end, the compromise idea was the 'Annihilator QV700', a slow-moving magic structure, which was not in line with the original design concept, but it also opened up another path of flexible construction.

One idea is a one-time flexible structure such as the Fire Djinn, since it is a one-time use, there is no need to consider heat dissipation, but the cost is high.

Moreover, the Fire Djinn's closed-loop device will also take up the efficiency of the Clockwork Elf's cooling system. Originally, Clockwork Elf could add a communication system in addition to a visual plug-in, which is the origin of Clockwork Elf Type II.

The Fire Djinn, on the other hand, can only be developed from Type I. Of course, apart from the real tyrants, it is impossible for ordinary people to consider using Type II clockwork goblins to commit suicide attacks.

But this strange 'clockwork goblin' in front of him was obviously beyond Fang Yuan's cognition.

But he didn't have to worry about it right away—

For Fang Yu raised his head and was looking at the darkness of this pitch-black orb, which was densely packed with countless - of course, for the sake of description, we could give this strange little thing a name for the time being, let's say, a pitch-black star.

Or something like that.

All in all, when these dark stars rise from the darkness one by one, they are like a little starlight, arranged equidistant in the vast space; It was as if a huge matrix stood up in front of Fang Yuan, and there were hundreds of such flexible configurations in front of and behind.

Fang Yu held his breath and quietly looked up at this scene, only one thought flashed in his heart: why did the room behind the red door bear the name 'Extreme Multi-Control'? Presumably that's why.

But when he looked back—the challenges of the world behind the door were always related to the alchemist—he couldn't let him, a weak combat craftsman, practice his evasion skills like a nightingale?

After going through so many doors, Fang Yu has gradually become familiar with the style here, and knows that there will definitely be a means to respond to challenges in this room. And it was at this moment that he suddenly felt some more underworld sensations in his heart.

As a combat craftsman, he is no stranger to such sensing. Because it was the Craftsman's Magic Furnace's sense of the Flexible Construct Resonance Crystal, "There is a flexible Construct without an owner," Miss Tata's voice came, and Fang Yu was actually aware of it, "On the top of his head." Miss Tata's calm voice came first.

Fang Yu raised his head.

He sensed that there was something in the darkness there.

Without hesitation, he raised the gauntlet of control, and sure enough, he felt the aether traction line in the darkness connecting to the top of the vault. Fang Yuan's mind sank, and he opened his five fingers to give an order, and suddenly there was a buzzing sound in the darkness - that voice was also very familiar to him.

It's the sound of clockwork elves.

Then in the darkness, a silver light appeared, and there were three strange 'clockwork goblins' one after another, and they flew down from that direction at his command.

Fang Yu looked at these three 'clockwork goblins', and was also stunned, it was really strange, he had never seen clockwork goblins of this category.

The three clockwork demons are silver-white, and the ornaments on the surface are not in the pompous style of this era—luxuriant flowers and leaves, but in reliefs like eagle feathers. Even above the sphere, a matching eagle head ornament is depicted.

Fang Yu understood at a glance that it was a giant eagle.

One of the sacred beasts of the Noumerin Elves.

"That's the Silver Chaser."

Miss Tata's calm voice came again.

"Silver Chaser?"

"I don't quite know what they're called in this era, but earlier, mortals called them battle elves." Miss Tata replied, "It's a blueprint that has long been lost, and in my time, mortals have been dedicated to recreating this large class of clockwork elves. ”

"Battle elves?" Fang Yu frowned, he seemed to have heard of this name somewhere.

But after thinking about it for a while, I remembered that this was not the direction that Elpahim's dwarven master was studying? It seems that to this day, people have not given up on the reappearance of battle elves.

Speaking of the dwarven alchemist, is it called Arquette or something. At that time, the dwarf also said that his thinking on the α crystal was of great help to his research on the battle elf, but he didn't know how the other party's research had been so far.

While Fang Yu was pondering, Miss Tata was halfway through her words when she suddenly reminded, "Be careful, Mr. Knight. ”

In fact, she didn't need to be reminded, Fang Yu had also seen that some of the pitch-black stars hanging high in the dark hall had begun to faintly glow red from the central beryl, and there were about seven or eight of them.

But he didn't hurry, and although he had never seen that kind of silver clockwork goblin, as long as the battle craftsman got in touch with a flexible resonance crystal, he would instantly know all the abilities of a flexible structure—

Of course, the Combat Tinkerer may not be able to use the artifacts because he doesn't have some specialized skills, but he'll at least get an idea of how many components the flexible build has through the information carved into the Resonance Crystal.

It's a conventional way of designing for flexible construction.

Therefore, as soon as Fang Yu raised his hand, the three silver clockwork elves simultaneously opened a light blue shield—each about the size of a medium-sized kite shield. He spread out the three silver pursuers at the same time, just enough to block almost all of his firing paths.

There was a flash of red light in the darkness, but almost all of the attacks fell on the three shields.

The high temperature of the red light before could even melt the floor of the hall, but now it fell on the shield, leaving only a few small points of light, which were fleeting. Only then did Fang Yu discover that these shields seemed to have extremely high resistance to elemental attacks.

"That's the Elemental Shield," Miss Tata explained, "it's designed to fight elemental attacks, but be careful, Mr. Knight keep the temperature down." ”

Fang Yu nodded.

But it was only the shock in the heart, not on the surface. As mentioned earlier, modern alchemists are not without a mind about clockwork elves, wanting to transform them into battle-ready constructs.

Because the speed and agility of the clockwork elf are the attributes that most combat craftsmen dream of.

However, most of these attempts have ended in failure, for no other reason than the cumbersomeness and complexity of the cooling system, which cannot be placed on a small and flexible structure. And even if the size of the clockwork fairy is further expanded, it will only end up with the 'Annihilator QV700' in the end.

Agility, flight, and attack seem to be an insurmountable barrier to flexible construction, and there is always no balance between the three.

Fang Yu used to know the same thing.

But this little silver clockwork goblin completely subverted his cognition.

Inside this 'Silver Chaser', there is not only a perfect observation device, but also a teleportation crystal, and even a self-balancing system, a shield and an attack subsystem, although he has not tested the attack method of this little thing, but judging from the ability of this shield, it must not be an ornament.

What shocked Fang Yu even more was that he was happy to see the hunter and tried to understand the internal structure of this clockwork goblin, but he returned in vain.

Because he found that his craftsman's abilities could not penetrate into it, at best he knew some of the external structure of this clockwork goblin. However, the more detailed parts, as well as the most important Resonance Crystal (the core crystal that can be flexibly constructed) and the cooling system, seem to have an invisible shield that prevents him from penetrating.

At first, Fang Yu thought that this was some kind of secrecy measure, but after further investigation, he found that this was not the case. The Craftsman's abilities were bounced out simply because he couldn't understand some of the basic theories that made up the Resonance Crystal and the heat dissipation system.

The invisible shield was not so much rejecting him as it was protecting him.

Because if the ether theory does not match, it is not uncommon for people to die on the spot if they are forced to understand.

The exquisite design of this clockwork fairy is simply unbelievable. However, thanks to his strong enough calculations, under the siege of seven or eight dark stars, he still has the leisure to explore these things. Fang Yu himself didn't know, but if he let the other craftsmen who had participated in this assessment know, he was afraid that his jaw would drop.

There are only a handful of people in history who can really survive the first wave of attacks.

However, there are still those who have the leisure to explore the clockwork goblin in their hands, and I am afraid that Fang Yu is the first one. But in fact, Fang Yuan was not only interested in the clockwork goblins in his hands, but even in those pitch-black stars.

After all, the clockwork goblin on the other side is also unheard of by him.

Don't talk about him, not even Miss Tata can say why.

"No need to probe, Mr. Knight," Miss Tata replied quietly, "The Silver Chasers are the work of the Noumerin Elves, and the alchemists of their time were also accustomed to using some elven spells, for mortals who do not have the ability to spell...... Some of the design ideas of that era are incomprehensible. ”

She continued, "Therefore, it is only natural that some of the skills have been lost, and most of the craftsmen of our time believe that the reason why the battle elves cannot be reproduced is precisely because of this. ”

Fang Yu had actually thought of this, but it was true that ordinary battle craftsmen did not have the ability to cast spells, but he suddenly thought of a person—a person who was both a mage and aspired to be a battle craftsman—and the latter really had a basic alchemist rank.

But this thought flashed through her mind, and Miss Tata had already reminded, "Be careful, Mr. Knight, the second wave of attacks is coming." ”

Fang Yu raised his head, and sure enough, he saw that more 'Pitch Black Stars' in the darkness had become brighter, they had only seven or eight bright spots when they first attacked, but now they were almost full of dark red 'Starlight'.

He knew at a glance that he couldn't block attacks from so many directions with the shields of three 'Silver Chaser's alone.

He had to take the initiative to attack, but it wasn't enough.

"There should be more silver pursuers up there." Miss Tata replied.

Fang Yu nodded.

This room is called 'Extreme Multi-Control', and there is no doubt that in each wave of attacks, the combat craftsman's ability to control the extreme is tested. And the skills to be tested in this level, to put it bluntly, are to fight more with more.

Thinking of this, he couldn't help but be stunned for a moment.

Speaking of which, isn't that the core idea of the Construct Lord?

However, thinking about it, Fang Plover still subconsciously raised his hand—there were indeed more inductions in the darkness that responded to his call, this time it was five—Fang Plover pressed his hand, and the five clockwork fairies sank downward, crossing a silver arc between him and the black matrix.

And the dark red light is converging.

At the same time, Fang Yu also clarified in his mind the amount of calculation required for each 'Silver Chaser', and amazingly, this kind of silver clockwork goblin required a slightly higher amount of calculation than the average clockwork goblin, but not too much.

It is mainly in terms of temperature control, but if the temperature is well controlled, the additional amount of calculation is not large.

This made Fang Yu think of Momiji, the other party is good at controlling the Annihilator QV700, and she is also a player who is quite good at controlling temperature, if she is here, it will probably not be too difficult. However, with all the mysteries of the silver pursuers, Fang Yu could only be attributed to the strength of the Numerin Elves at the moment.

After all, the alchemist is also the latter's gift to mortals.

It's like the Zero Crystal that Hayne Sail left to him and to the world.

And Fang Yu has completely calmed down at the moment-

After all, he may not be so confident in other aspects, but when it comes to calculations, even if there is no help from Miss Tata in the world behind the door, he is confident that he can stand out from the crowd. After experiencing so many events, Fang Yu already knew that his computing power was basically at the monster level.

With only eight Silver Chasers, this amount of control was not a big deal for him at all - he even had the time to split the Silver Chasers in two, taking charge of attack and defense on the other, playing a coordinated game.

The attack of more than a dozen pitch-black stars was easily blocked.

But it is clear that the test is not over, or rather has just begun. The dark red stars rose again, and this time the number doubled again, reaching the size of more than twenty attacks.

And this time, the silver clockwork goblins that appeared from above the vault were seven, and Fang Ou's mastery of the clockwork goblins had reached as many as fifteen at one time, and this number was almost the limit before his party in Fenris.

Fifteen versus twenty, however, the result has not changed.

In the fourth round of attacks, the world behind the door seemed to take into account the limits of the craftsmen, and the intensity of the attack began to weaken somewhat, and this time only ten pitch-black stars joined the attack sequence, bringing the scale of the attack to the order of thirty.

Fang Yu didn't feel any problem at first, after all, he could also further increase the number of controls, although he had to dodge in the staggered red light from the beginning of this round of attacks, but he could still fight back and forth.

This time he was a little slower, and it took him a full five minutes and the loss of two clockwork elves to get through.

But in the fifth round of attacks, when the remaining twenty pitch-black stars were activated at the same time and added to the attack sequence—the number of pitch-black stars still alive on the scene once reached about forty-five to fifty—although the attacks of these pitch-black stars were more rigid and easy to deal with, Fang Yu didn't need to really manipulate the same number to fight against them.

But all of a sudden, he felt something was wrong.

Sure, he's capable of manipulating twenty or thirty clockwork goblins, but what about the others?

Fang Yu recalled it at this time. Theoretically, even in the last wave of attacks, he believed that few combat craftsmen of the same level could hold on. Not to mention this wave, even he feels a little reluctant, whether he can succeed or not is still a matter of two words.

As for the others, he felt that the problem could be big.

So the question is, how did the others get through?
