#329 - Chapter 329: Oxygen Conversion Lamp

Their walking order was: Xiao Xin, Sikong Yaoyao, Qi Jing, Tan Zuoyin, and Xiao Yao.

Xiao Yao, the strongest in combat, walked at the very back, ready to guard against enemies suddenly appearing from the front or rear. Moreover, since this was an underground tunnel, beasts could potentially burst out from the walls on either side, requiring her to take action.

Xiao Xin walked at the very front, firstly because she had more exploration experience and a strong sense of perception, allowing her to sense danger; and secondly, because she possessed powerful vitality and healing abilities, making it difficult for her to die quickly in the face of danger, making her suitable for scouting ahead (attracting danger).

As for those in the middle, of course, they could walk however they pleased. The two of them simply hadn't factored the combat strength of these three into their considerations.

"Let me see what's in this cave."

Xiao Xin took the lead and walked into the cave entrance, which was about four meters high. She initially thought it would be a small room, but unexpectedly, she was met with an earth wall. No, it was that the cave's direction suddenly made a right-angle turn.

After walking a few more steps to the right, the passage ahead was suddenly blocked by a complete stone slab.

Under the faint blue light, the stone slab emitted a faint purple glow and was engraved with several black lines, clearly indicating that it was not a simple object.

"A magic door?" Sikong Yaoyao asked.

This thing looked like a magical artifact that would only be encountered when exploring underground labyrinths in Western fantasy novels.

"It's not a magic door, but it's close. It seems its energy has been exhausted."

Xiao Xin inserted her right hand into her pocket, and when she pulled it out again, she was suddenly wearing a glove made of an unknown material.

"Full of vitality!"

One punch, two punches, three punches!

With a crash, the stone door was shattered into pieces by her three punches.

"Wow, so amazing!"

Xiao Xin thoroughly enjoyed the feeling of having fans, and waved her hand lightly: "It's just so-so. I can only use brute force. I'll go in first, and you guys can come in after I confirm there's no danger."

Having already seen through the scene inside with his Observation Haki, Qi Jing asked Tan Zuoyin, "Zha Yin, guess what's inside?"

"I guess it's some furniture."

"You guessed right. There's only a stone bed and some stone utensils inside, nothing else."

Sikong Yaoyao came over and asked, "How do you know?"

Qi Jing spread his hands: "Because I have a wide-range perception skill, I can see within a few hundred meters."

He really hadn't used this ability in front of Sikong Yaoyao before, and even if he had, she wouldn't have been able to see it, so it was normal for her not to know.

"You have this skill and didn't say so earlier, why were we being so apprehensive?"

"Isn't it to add some fun to the adventure? If I told you everything, what kind of adventurer's experience would you have?"

Mainly, within the underground environment, Qi Jing's Observation Haki could see too many things, overwhelming his brain, so even though its range was very wide, he could only focus on exploring things at a closer distance.

Unlike on the ground, he only needed to observe places out of sight and a small distance underground.

Sikong Yaoyao pointed at him: "You, I'll give you that one."

"Come in."

Xiao Xin's voice came from inside.

After entering, they observed the room. It was almost identical to the corridor, as if a small section had been cut off from the corridor and placed here, with a bed placed at the very end.

No wonder Qi Jing couldn't find anything when he looked at the underground room through the ground-penetrating telescope. It turned out he had mistaken the room for the corridor.

"Besides the bed and some bottles and jars, there's only this thing here, so this should be where those cave creatures sleep."

Xiao Xin examined the only thing in the room that emitted light besides the glowing ground—the chandelier on the ceiling.

Unlike the blue light emitted by the ground, although it was also emitting blue light, its light had already become very dim, almost as if it didn't exist.

If it weren't for her smart goggles being particularly sensitive to color changes, she really wouldn't have been able to notice it with the naked eye.

"Take it down?" Xiao Yao asked.

The moment Xiao Xin nodded, the circular chandelier fell down together with the soil above, and was steadily caught by Xiao Xin.

Qi Jing looked up, and a semicircular gap appeared in the position where the chandelier had been hanging, very smooth, as if a piece of tofu had been hollowed out, or perhaps it was originally shaped like this, without any traces of modification.

Such fast attack speed and precision!

"This is an oxygen-generating device, and it's still working now, wow, amazing!"

After observation, Xiao Xin discovered that the circular chandelier in her hand was weakly converting oxygen outwards, but the speed was very slow, slower than a small grass.

But this was craftsmanship from who knows how many years ago, and the fact that it can still be used now is already very remarkable!

"Not a lamp?"

"It might have had the function of a lamp before, but I think it's mainly used as an oxygen converter."

After getting off the elevator, Xiao Ling had sent them some information, including the air index along the way.

According to Mo Wang's air component analyzer, the oxygen content here was as high as 89 percent when they first arrived, which must be the credit of this thing.

"It should be able to convert nitrogen into oxygen, amazing, take it back."

If it were converting carbon dioxide into oxygen, the oxygen content wouldn't be so high.

The first useful trophy obtained.

"Let's go, continue exploring downwards!"

Xiao Xin walked out excitedly, and Qi Jing pulled Tan Zuoyin to silently follow her steps.

In the following time, they found several caves like this, but just like mass-produced copies, these caves had almost no differences, and not even a single additional piece of furniture was placed.

After a trip, the only items they scavenged were a few nearly expired chandeliers and a few expired magic doors.

Even Senior Aunt Xiao Xin couldn't help but get bored with this monotonous exploration:

"Xiao Qi, in the future, when we encounter caves, you should use your perception skills to sense them first, and then we'll decide whether to go in or not. They're all the same, so boring."

"OK, leave it to me."

Qi Jing didn't feel bored at all, because he was practicing ambidexterity.

The left brain uses Observation Haki to sense the surroundings, and the right brain listens to novels.

If he could do two things at once, then it wouldn't be a problem for his left hand to use the Dugu Nine Swords and his right hand to use the simplified version of the Golden Skyline.

I'm simply a genius!

"Hey, hey, hey, Qi Jing, take a look at what's going on inside here?" Sikong Yaoyao woke up Qi Jing, who was praising himself.

"Ah? Oh."

It's another cave, let me see.

"Something's up! The room here is different!"
