The escalator leading to the underground passage is narrow and steep, and it is difficult to allow two people to go down side by side. If you are not careful, you may fall down. Although it is only about five meters high, there are also many dangerous components.

But this was not a problem for Su Wen. He first quickly landed in the middle of the escalator, and then raised his feet with one hand to hold Liticia's stretched down. From this angle, Su Wen could see what was under the latter's skirt, but he was only concerned about escaping and didn't care about these things at all. The mental blow caused by Shirley to him was so strong that it was difficult to describe it in words, which made him completely useless to pay attention to irrelevant details.

When her feet were stepping on the mud ground, Su Wen suddenly let go of her left hand that was almost dragging the weight of Liticia. The latter let out a slight panic cry, and was then steadily caught by Su Wen. Holding the waist of the half-elf maid, Su Wen felt that her weight was too light, and then regardless of her futile struggle in her arms, he placed her feet on the ground in the passage behind him.

"I forgot something to wait here."

Su Wen said, then rushed up the escalator like a monkey, turned over and returned to the room, rushed to the desk in three steps, and took away the transparent jar on the table. Well, Su Wen swears that this was just a mistake. After all, the saint would make a mistake. He admitted that he had almost forgotten this liquid contract partner. Fortunately, he suddenly remembered it when he entered the tunnel, which did not lead to worse results...

Back to the tunnel, close the trap door, and reach out to see your five fingers in the dark without any light source.

"Let's go, this secret passage can lead directly to the outside of the city."

As he said that, Su Wen shook the jar in his hand, the liquid inside rustled, and then a slight light lit up. However, the light was dark green, and it was too faint, so that the narrow tunnel was reflected like the world in a horror story.

Liticia looked at the jar, as if she noticed that it was not a simple luminous liquid in the bottle, but a slowly squirming life.

"What's this?"

she asked softly.

"Slime, I'm caught as a pet." Su Wen didn't feel any hesitant at all. He shook the jar in front of Liticia again, and stopped until the fluid inside was shaking. "It's very cute. This kind of small animal is often seen in adventure novels, and it is also very popular in the ghost-and-animal literature of the last era. What's more, he has developed secondary creations such as Slime Girl, which is really interesting."

These are all the experiences that Su Wen has been in the library for half a year, condensing rich experience and wisdom. At this time, he saw that his maid rarely expressed interest in his own things, so he naturally would not miss this opportunity that might be able to regain a certain degree of favorability, so he introduced it all in his knowledge: "This creature can be freely deformed, soft mucus can wrap any object, and it can be changed into the shape needed everywhere, so he can play multiple roles in the plot of tutoring, and is widely loved by everyone... Hey, Liticia, wait for me, I haven't finished talking yet!"

Seeing the half-elf maid turning her head silently and walking towards the depths of the tunnel, Su Wen realized that he had missed this rare opportunity, so he had to sigh softly and quickly followed. But before Su Wen could catch up with Liticia, a disgusting voice came from the front.

"Stay away from me."

So Su Wen's sigh became even more desolate.

As expected, Liticia has had deep grudges with herself. Even if she wants to gain favor through what she is interested in, it is not so easy to do.

But from the bottom of my heart, Su Wen still hopes to have a good relationship with Liticia. After all, in addition to always being rude when talking to herself, this half-elf girl can do everything the maid should do. Su Wen can only describe this as very satisfied.

It seems that I can only find a way slowly in the future.

...

The ventilation effect of authenticity is very poor, especially the two people who passed through the authenticity this time.

Therefore, after walking only more than one kilometer away, Su Wen suddenly realized that Liticia in front of her was shaking a little, and her breathing became more and more rapid.

This is obviously a symptom caused by hypoxia. Su Wen has a strong body and can force herself to hold it back. However, as a half-elf with thin bloodlines, Liticia has not inherited any noble bloodlines of her ancestors except for her appearance and the characteristics of her elf ears. Therefore, it is no different from ordinary human weak women. It is not surprising that she cannot bear the poor ventilation in the tunnel.

But thinking that the distance was still halfway, Su Wen felt that it was getting worse.

This passage is deep underground, and it is old. Most of the vents are blocked or squeezed and deformed. The effect is not one in ten. At most, it depends on some narrow gaps to ensure the slow circulation of air. Usually, Su Wen passes through by himself and the oxygen is just enough, and even so, he feels short of breath and chest tightness when he reaches the end. Unexpectedly, he takes Lyticia rashly through this time in a hurry. The air here will be consumed so quickly!

Su Wen looked up at the extremely limited space around him, and cursed in his heart why the authentic original owner did not make the wider, so that there would be no problem of insufficient oxygen. But no matter how he cursed, Su Wen could not change the embarrassing situation he gradually discovered: that was that he and Liticia walked to the center of this underground passage, and the air was so turbid that it was almost unsuitable for breathing.

If you are unlucky, you will get too stuffed with your teeth if you drink cold water!

As time passed, Liticia's walking speed became slower and slower, and she finally had to hold the wall beside her to move slowly. Just as Su Wen was thinking quickly how to deal with the problem of insufficient oxygen, she suddenly realized that she could not hold on. Her body suddenly lost control and fell softly backwards. The back of her head was about to collide with the ground covered with stones... The sudden change scared him to stop thinking immediately, rushed forward and stretched out his arms, and finally caught Liticia.

At this time, Su Wen's forehead had already burst out. He knew very well that this seemingly shortcut hidden passage had become a dangerous area that could kill people without realizing it! The regret for him ignoring the details and his apology for Liticia came to his heart, but Su Wen knew that he could never stop at this time - in such a place where he should not be called "the earth is not effective every day", there is only a way to die if he stops.

It is impossible to return the same way. At this time, I have already walked half a journey and can only break to the end of the tunnel!

Liticia, who was supported by Su Wen, had already fallen into a semi-coma state. Her breathing became very rapid. Through the faint fluorescent light emitted by Slime, Su Wen saw a faint fear in her half-open eyes. He had to pick up the half-elf-like maid, which was as light as nothing, on the waist, but this time he did not encounter any resistance. Liticia just leaned half-resisted on Su Wen's chest and looked at her with an incomprehensible look while half asleep and half awake.

Su Wen knew what to do at this time. While holding Liticia, he squeezed towards the end of the tunnel as fast as possible, he reached out and patted her face.

"Hey, don't fall asleep, you'll die."

"Um……"

Liticia's voice was very soft, and Su Wen had never heard such a soft voice in her maid's mouth.

"Come on, bite my arm, the stronger the better."

As he said that, Su Wen put his hand holding the slime jar to Liticia's mouth. The latter was not polite at all and bit it with all his strength. Silently endured the pain from his arm, Su Wen felt that Liticia's teeth were piercing his skin and blood was slowly seeping out.

As the air in the tunnel became more and more turbid, the two of them breathed faster and faster, and soon they changed from two or three seconds to two or three times per second. Especially Su Wen, who was struggling to pass through the tunnel, his physical strength was difficult to replenish oxygen during the rapid consumption, and more fatigue and fatigue accumulated in every inch of muscle, but even so, he still tried his best to slow down his breathing - the oxygen in the air was constant, and the more he breathed, the greater the danger of Liticia.

Fortunately, there were places in front of me that I had never walked before. Although the air was still very turbid compared to outside, it did not completely suffocate Su Wen.

After nearly ten minutes of sprinting during this stuttering process, with the help of the slime light in his hand, he finally felt the existence at the end of the tunnel. However, at this time, the force of Liticia biting Su Wen's arm was already slight.

"Hu...hu...Litsisa, don't fall asleep!"

While excited, Su Wen, who was drowsy in his mind, subconsciously looked down, but was almost scared to death. He patted the half-elf maid's face again, but the latter had no reaction at all. Su Wen could not care about more, so he raised Liticia's arm and bit it hard without hesitation. As the pungent blood flowed out, the girl in her arms finally had a slight reaction. Her body trembled with a very light amplitude, and her tightly closed eyes opened the narrow gap.

"Wake up, we're almost here! It's almost here!"

Su Wen was overjoyed and sprinted at a faster speed than before.

Of course, the tunnel is not flat. The walls carved out by hand and the zenith that are barely tall are everywhere. Su Wen has long been touched many times after running down the road, but at this time he has turned a deaf ear, with only the exit hidden in the darkness in his eyes.

It's close...

It's close...

Finally...arrived!

Su Wen's eyes were covered with blood. He felt that his physical strength had already exceeded his limit. Although he was only a narrow tunnel of three kilometers, it was even more uncomfortable than doing his best to sprint for 20 kilometers. Su Wen's lungs were tingling, and there seemed to be countless subwoofers in his brain. Until now, he was a little unbelievable. Why did this feeling of life just by passing through this poorly ventilated tunnel?

Yes, the air in the tunnel is consumed too quickly from the beginning of halfway through, right?

Before he could think carefully, he rushed to the end of the tunnel. Su Wen saw the high escalator on the wall and had the urge to burst into tears. Without any pause, he hugged Liticia, who was in a coma again, and climbed up like a wolf. When he used all his strength to send his left fist and knocked open the semi-closed door panel, the fresh air that poured in overwhelmed him suddenly rushed into heaven at the bottom of hell...

It's great to be alive!

Su Wen laughed and sent Leticia out.

The maid who had already been unconscious rolled in the dense weeds in the woods, as peaceful as if she was asleep. The sunlight casts spots through the dense forest, reflecting on her body and face, and her lips that are particularly purple due to lack of oxygen, making her look pitiful.

Su Wen followed him to the ground, slumped in the grass and breathed in the fresh air. He was very glad that he finally rushed to the exit when he was about to be unable to support him. Although Su Wen's clothes had long been scraped to pieces and were covered with a large amount of blood from the cut wounds, it was the first time in the past six months that he felt that his breathing was so refreshing and silly.

However, this refreshing feeling didn't last long.

Because Su Wen soon discovered that Liticia, who was lying beside him, was still in a coma and showed no sign of waking up...

——Separation line—

At the same time, in an empty alley in Trides City, a sweet smile was hanging on her blue-haired Shirley's face, and she gently placed her slender and white palm in front of a cracked gap in the corner of the wall. In her hands, a light green magic circle appeared in a flash, and the whistling wind rushed out from the gap, but due to the blockage of the magic circle, no outside air could convection with them.

In other words, under Shirley's control, the air through this gap only came out but not in.

"Sister Shirley, it's too troublesome to take the air in the tunnel. Why don't we kill him directly?"

Next to Shirley, the well-behaved little loli in the robe stared at the sound of the wind coming from the gap and suddenly asked.

Then, Shirley gently patted her head.

"Of course I have another purpose." Shirley did not look back when she spoke, but her voice was majestic in her tenderness, as if she was scolding the naughty child. "But you, Luluri, are there only two kinds of creatures in your eyes that can be killed or not?

"Isn't it better to kill something that I think is troublesome?" The little loli in the robe curled her lips. Although she could not see her face clearly through the hood, her expression must be very stubborn at this time. "That's right, why did Sister Shirley ask Lulurui to hold back just now? Such a weak little bug can be killed with just a little effort! He was so angry that he dared to touch Lulurui's head. No one can touch Lulurui's head except for her parents and Sister Shirley!"

"It's a pity that the world is much more complicated than you think. There are many people who can touch your head like this, besides what you said." Shirley shook her head helplessly. She waved her hand and dissipated the wind-type magic array in her hand. The crack that lost the blockade of the formation suddenly began to inhale due to the air pressure gap. "There are always those people who you want to kill but cannot kill after touching your little head, such as my unforgivable cousin."

When Shirley heard the terrifying figure in red robe, the little loli with her robe squatting on the ground suddenly seemed to have a nightmare, hugging her head tightly with her hands and trembling.

"Yeah! Sister Shirley, don't mention that guy, I... I'm going to cry!"
