The little girl looked relaxed, but Masha didn't.

He was constantly adjusting his perspective and alerting him to the surroundings.

He saw the mouse.

——Wait, is the Darwin School opposite?

Masha immediately realized something was wrong with the mouse.

——Aggressive Meow, remind the little girl to start moving again!

The little girl may have felt relieved after she knew that the brother had reached out to help, so she was a little lazy.

She stopped in front of the same grille for a while, and was constantly moving back and forth to see the changes in the grille under the ruler shrinking effect.

——To be honest, the little girl seems to have already ignited her enthusiasm for learning. After this incident, she will definitely come and ask me what the ruler shrinking effect is.

——The premise is to sneak out of the enemy this time.

**

Ma Xiaomei was scratched.

Very light, but she felt it.

She stopped studying the grille that constantly deformed with her movement state, looking down at her hands.

There are fine red marks.

——It looks like a cat is scratching? Why did my second brother suddenly let his cat scratch me at this time?

——Is it a reminder that the enemy is coming?

The little girl turned her head and looked around, and then she saw the mouse.

She also reacted immediately.

——Darwin School! Mouse! I was discovered!

At this time, the best way is to use magic without ballistics to kill the rat immediately.

After all, mice do not use spiritual magic. If they want to inform them, they have to use traditional methods, such as yelling, or looking back to the owner.

The mouse chose to turn his head and run away.

The little girl has completed casting: "Petrified Eyes!"

Theoretically, the most suitable spell at this time is the law of death. A mouse will definitely not pass the law of death exemption and will take effect after taking action.

But the little girl is just a ten-year-old girl. Not to mention the death of the eight-ring law, she can't even use the lower spell.

In fact, her ability to use petrochemical gaze is already a talented category.

Even if Ma Xiaomei doesn't become a Frankenstein and honestly moves forward on the path of a magician, she can still have a bright future.

However, Ma Xiaomei didn't know that now that the speed of light was limited to the speed of human running, the petrified gaze could not be regarded as a spell that was inactive without ballistic action.

There is a huge difference in concept between this spell and the "instant instant" of the Eight Rings' Law Death.

Petrochemical gaze can actually be regarded as a spell with ballistic speed as the speed of light. It usually seems to be "instantly effective", but because the speed of light is particularly fast, the delay in effect can be ignored.

The Death of the Law is a conceptual spell. Although it requires a visual target when casting, it is mainly to lock the spell. Once the casting spell is completed, the effect of the spell will occur instantly at a more basic level.

This is the basic qualities of all law spells.

At this moment, Ma Xiaomei did not realize that the speed of light was limited, and naturally she would not know that the petrified gaze could no longer be regarded as a ballistic instant effect spell.

So when she saw that the mouse was not petrified but ran away in a flash, she was in a bad mood.

"Why!" she shouted.

**

Masha judged that Ma Xiaomei should have cast a ballistic attack spell with no ballistics based on her own magic knowledge.

However, the so-called lack of ballistics is limited to the situation where the speed of light is 300,000 kilometers per second.

Now that the speed of light is limited to the speed of human running, this spell has ballistics and flight time.

So the mouse ran away.

It’s not the little girl’s fault, she has made the most correct choice within her cognition.

The failure was just because she didn't understand the working principle of the pocket watch.

Masha’s love for this sister has now reached a new level - who doesn’t like such a capable sister?

But now the most urgent task is to let the capable girl run away immediately.

Fortunately, although the little girl was surprised why her spell didn't fuck the mouse, she didn't spend her time thinking about it, and she had already started to slip away.

She crawled quickly in the pipes at an amazing speed. It was obvious that this was not the first time she used ventilation pipes to run around in the Marquis' Mansion.

This world is a magical world, so ventilation ducts are also magical.

In order to pour fresh air into buildings that need ventilation, the earth's ventilation ducts will be equipped with many fans in the ventilation ducts.

But these responsibilities in the world of magic are borne by magic runes that appear once every seven or eight meters on the pipe wall.

The magic runes ensure that the air flows in one-way in the same sub-pipe, replacing the fan blades that will block the girl's way.

The little girl walked smoothly all the way to the central shaft of the ventilation duct.

She used the air-dance technique to float herself up, then plunged into the shaft and began to move vertically between the floors of the Hou Ye Mansion along the shaft.

You can tell at a glance that she is proficient in this technique.

Masha turned his perspective and watched the enterprising meow jumping on the side of the shaft.

Then, a mouse appeared at the entrance of the passage on the side of the shaft.

——Damn, I knew it wasn’t that simple to run away.

The enterprising meow jumped over and killed the mouse with one catch. The mouse would definitely not see the enterprising meow, so its survival instinct did not have any warning to the natural enemies that were flying over.

The little girl continued to descend along the shaft.

Suddenly she said, "This floor is good!"

She raised her hand and opened the iron fence at the connection between the shaft and the horizontal pipe, and drilled into the pipe.

At this time, Masha heard a commotional sound from the shaft behind him.

It sounds like a large number of rodents running.

The dense sound of tiny claws hitting the metal walls of the shaft made Masha's head feel goosebumps.

He was not at all confused about how rodents would climb the metal inner wall of the shaft - that was a rat created by the Darwin School. It was probably a species specially used for detection. Is it strange to be able to climb metal walls?

The little girl also heard the sound. She threw a large piece of cake behind without looking back, and then used her hands and feet to crawl faster in the pipe.

Fortunately, pocket watches restricted the movement of rodents so that they could not exceed the speed of humans running, so Masha waited for several seconds before seeing the rodents drill into the horizontal pipe from the connection that the little girl broke.

The mouse's red eyes were densely packed, and it was quite terrifying to look at it.

The little girl turned her head and looked at it, and then crawled faster.

Her current speed may easily exceed the speed of elite soldiers crawling forward on earth!

Masha even felt that the little girl in her eyes was about to be in trouble.

Then the cake that the little girl threw just now was fried.

Masha was shocked because he was very sure that the little girl had not cast a spell, so it was obviously not a cake that the little girl used magic to detonate.

Moreover, to be honest, the scale of this explosion is a bit small.

It is clearly in a narrow space like a ventilation duct, theoretically, shock waves and air waves will travel far along the duct, but only a slightly stronger gust of wind caught up with the little girl from behind.

——What the hell? What did this little guy do to the cake?

At this time, the little girl laughed: "You are so hungry to eat cake!"

Masha thought about it and understood.

The little girl probably buried the bacteria inside the cake and put them in the bacteria that would shine and heat when exposed to the air and then die quickly.

When a mouse eats the cake, it releases methane inside the cake, and at the same time allows the bacteria that act as a fuse to contact the air, shine and heat.

——So the power is low because there is not enough time to generate methane, and the methane is not fully mixed with air and is ignited by the "self-destruction" of bacteria?

——So great, sister, you are so capable!

——If this is a card draw game, you are definitely SR! No, it is ur! More awesome than SR Grass!

Masha was admiring, when the grille on the left side of the pipe in front was suddenly pulled open from outside.

Then the snake girl, who had been kissed by the little girl before, touched her scales with her face.

"I found you, sweetheart!" The weird man from the Darwin School grinned and his eyes narrowed into thin slits.

Masha subconsciously let the enterprising cat go up and scratch this guy.

However, the cat's claws scratched the snake's scales.
