Leo agrees with Carl's speculation.

can make the monsters on the 4th floor collectively silent,At present,There are indeed only two possibilities.。

Either their intelligence, which has evolved to give them priority to sneak attacks, is undoubtedly extremely tricky.

The other is because it is in the Institute of Science and Technology...... To be precise, in the area on the 5th floor, there is an extremely powerful monster.

The strength of this monster is so strong that even with its momentum alone, no insect slave in the area around the Science and Technology Research Institute dares to step into the area.

Often in things like feeling the aura and might of the enemy, the insect slave, a monster that is already close to a beast, will become more acute.

Originally, Carl was slightly skeptical about whether there was a powerful monster in the Science and Technology Research Institute.

But judging from the performance of the monsters on the 4th floor, perhaps, in the 5th floor, there is really an incomparably powerful monster!

"What now? Carl, I think you should have no problem finding those hidden monsters, right? Leo frowned, a little tangled.

As the level of the battle became higher and higher, he also found that the silver vision trick was gradually unable to meet his needs during the battle.

Although the silver vision can provide additional functions such as farsightedness, dynamics, and night vision, it is still much weaker than Carl's current fire phoenix vision.

The most important point is that Carl's fire phoenix vision has a thermal energy sensing effect, in this kind of environment where all enemies are hidden, the thermal energy sensing effect is simply invincible for Carl.

Imagine when you've gone to great lengths to hide in the shadows and deal a fatal blow to your enemies.

As a result, in the eyes of others, you are like a bonfire in the dark night, emitting an incomparably bright light.

In this case, let alone a sneak attack, I am afraid that someone else will counterattack from behind, and you may not be able to find out.

This is the effect of thermal induction, and any dynamic unit of biological or mechanical thermal energy can be clearly captured by Carl.

After hearing Leo's words, Carl's eyes with flames began to scan back and forth throughout the space on the fourth floor.

After a careful investigation, Carl quickly said: "In this space on the fourth floor, there are about a dozen monsters in total, and from the appearance, they are also a kind of fusion monsters in terms of physical limbs......"

As he spoke, Carl silently wiped the sweat from his forehead.

Even if he only used thermal energy sensing to probe the biological heat energy of those monsters, when he carefully observed the specific appearance of those monsters, he was still extremely unhappy by the scene in front of him.

The creeper's body, however, was forcibly mixed with the limbs of countless other insect colonies...... The mouthparts of a venomous dragon stabbing snake, or the blade of a double-edged mantis......

All kinds of biological weapons, more or less forcibly grafted onto those monsters.

The strange shape is not even enough to describe the appearance of these monsters, and the most intuitive way to describe them is to be miserable.

What kind of person is this Dr. Vincent, who has so many strange ideas......

"It's just a dozen, and the number is about half less than that of the third floor...... Karl, get them done first, and then go up? Leo said with a twinkle in his eyes.

Carl glanced at Ou with a strange expression, which was not like a choice Leo would normally make.

On the contrary, John, hearing Leo say this, could not hold back his killing intent for a long time, and said with some excitement:

"Carl, tell me quickly, where are those monsters hiding, you don't have to do anything, you can leave it all to me!"

Carl naturally wouldn't give all of these monsters to John, and since he had decided to get rid of them all, he had a lot of ways to force them to show up!

As soon as he thought of this, Carl held his Luanfeng musket, and without saying hello, he quickly pulled the trigger.

Countless fire phoenix missiles, under the control of Carl, quickly flew towards some specific areas.

After these fire phoenix missiles hit the obstacles, they did not explode on the spot, but left dazzling fire phoenix symbols on the walls and those obstacles.

After marking all the monster hideouts, Carl smiled and said, "Okay, I've marked all the monsters lurking on the 4th floor, five minutes, enough to deal with them all, right?" ”

"Still need 5 minutes? You're underestimating us! John clenched his fists with great confidence, and when Karl gave the order, he would rush out without hesitation.

Leo quickly grabbed him from the side, and said with a serious gaze: "John, these 5 minutes are not so easy to solve!" ”

After saying that, Leo looked up at Carl, who smiled slightly, and added at the same time:

"That's right, don't look at these monsters lurking in the shadows now, that's because they don't know we've figured out where they are."

"But once we start killing them, I'm afraid they'll react to stress as soon as possible!"

"It's okay, I'm going to fight sooner or later anyway, even if they react, I'll take care of them all!"

Listening to John's confident words, Carl furrowed his eyebrows, feeling that his reaction seemed to be a little too excited...... Thinking of Leo's abnormal performance just now, Carl suddenly smiled.

"John, Leo, are you two about to break through?"

When Carl asked this, John and Leo were stunned for a moment, and then nodded in disappointment.

"Originally, we were still thinking that after breaking through to the title level, we would give you a surprise ......"

"yes, how did you suddenly guess that? We didn't tell you that! ”

Carl smiled and said a little proudly: "No way, although John is as excited and belligerent as ever, but Leo, you actually took the initiative to ask to deal with these monsters, it is really a little too abnormal." ”

"If you were an ordinary person, you would never have fought these monsters forcibly. So why do you have to fight them......"

"The only reason, I think, is that I am close to a breakthrough, and I want to use this battle to help you get promoted."

After listening to Carl's analysis, John and Leo couldn't help it anymore and both laughed. After all, as Carl said, the two of them both felt an impulse of the battle spirit power in their bodies after the battle just now.

This familiar fluctuation of battle spirit power made the two of them understand in an instant, this is about to be promoted!

And for the Battle Spirit Samurai, fighting is always the fastest way to advance. That's why, from just now, Leo and John would be so eager to fight.

"Okay! Since you are all close to breaking through, then I won't interfere with the monsters on the 4th floor, and I'll leave it all to the two of you to deal with! ”

"Well, I'm funny, right?" Karl smiled and took the initiative to take a step back.

It's obviously a science and technology research institute with a weird environment, but in the three of them, it's like they're happily playing games.

John and Leo glanced at each other at this moment, and a flash of war intent quickly rose in their eyes.

With a bang, the two of them quickly killed the monsters where they were hiding.

In terms of movement speed, Leo, who has the spiritual power and spatial ability of the wind battle, is far ahead of John.

In just two breaths, Leo had already appeared behind the first monster, and with a wave of his hands vigorously forward, two hyperspace dimensional slashes were neatly cut off the monster's body.

After dealing with the monster, Leo just wanted to get up and continue to move in the direction of the next monster, when John finally arrived.

Although it had only been 3 seconds since they set off, after Leo had moved, attacked, and other actions in one go, these 3 seconds seemed incomparably long.

Compared to Leo's elegant operation, John seemed more rough at this time.

After flying quickly to one of the hideouts, John let out a soft snort, ignited flames with his hands, and threw a fierce punch at the hideout in front of him.

The thick flames swept towards the area as if they were real objects.

Receiving this fierce fire attack, the monster hiding in finally couldn't stand the heat and was forcibly driven out of the hideout.

But before it could launch a counterattack against John, John controlled the remaining flames, completely enveloping the opponent in mid-air.

The strong burning sensation directly made this monster let out one wail after another, and such a huge movement also caused the other monsters who were hiding to riot together.

The whole body is moved, and the entire 4th floor finally becomes lively.

"Damn! John, you're doing this, but you're causing me a lot of trouble! Leo yelled at John in the distance, with some dissatisfaction.

Anyway, now that all these lurking monsters have appeared, it would be a bit redundant to deliberately hide their figures.

Hearing Leo's complaint, John didn't have a guilty expression at all, but said in a straightforward tone: "What's not troublesome, anyway, these monsters have to be solved in the end." If you don't hurry up, the Thorn Squad guys will catch up! ”

You really make sense when you say that...... Leo inexplicably flashed such a sentence in his heart, and in desperation, he could only join John's team and deal with these ugly monsters head-on.

In fact, the reason why he chose to solve those monsters secretly was only due to Leo's own habits.

But when he really chooses to be tough from the front, just like John, his attack is not weaker than John's at all.

Even, the means of his frontal attack should be more diverse.

Whether it is a hundredfold heavy punch, a hyperspace dimensional slash, or an attack method such as Pure Flame, it is far more gorgeous and efficient than John's Fire Fist.

These monsters in the entire 4th floor space were quickly destroyed almost visibly under the wanton attacks of John and Leo.

In fact, if these monsters were to face other opponents, Dr. Vincent's modification of them might be of great use.

However, they are now facing three freaks such as Carl, John, and Leo, and in the group of title-level warriors, the combat power of the three of them has always been at the top level.

Suffice it to say, if these monsters don't have some special attacks, or if their flesh is greatly strengthened like a creeper.

No matter how many of them are, it will only be a difference between one attack or two attacks in front of Carl.

Finally, after ten minutes, John and Leo had finished dealing with the last two remaining monsters, and they both stopped quickly.

Leo was still standing in place, gasping for breath, but on the other side, John took a step forward in surprise, and with a low cry of mouth, a thick flame rose rapidly from under his feet.

"It's ...... Promoted? Karl saw John's strange appearance at a glance, his face changed, and he read with some excitement.

Leo smiled bitterly in the same place, but he still took a step slower, allowing this guy John to break through to the title level first......
