Chapter 626: The [Hunter] that had once appeared in the subterranean world!

Cold sweat streamed down Heimerdinger’s forehead.

This [Zero-Number Life Detector] was not a mass-produced item.

It had been manufactured with the strongest creature he had ever seen as its upper limit.

He had never seen a Black Dragon.

But he had seen the most powerful dangerous species the subterranean army had hunted to date!

It was an extremely terrifying creature.

He never expected that in front of this guest, it wouldn't even last a single second.

It just... exploded like that?

It seems

yesterday’s hypothesis must be true.

This respected guest truly did scare off the Black Dragon God!

And at this moment,

the astonishment in Li Yao’s heart was no less than Heimerdinger’s.

His life force actually couldn't be considered strong.

The momentum he projected

was more of a collective aggregate of all his strength.

This instrument must have had a reconnaissance-type array attached to it.

This Yordle senior before him must be a master highly skilled in arrays.

After a long while,

Heimerdinger broke the silence and spoke: "Guest, you aren't a 'person' of the subterranean world, are you?"

Poppy, standing to the side, looked startled and turned to look at Li Yao.

"That’s right, I come from the surface, from even further away," Li Yao did not hide it. "Senior can just call me Li Yao."

"Then may I ask, Li Yao, what is your purpose in coming here?"

Li Yao chuckled, "Actually, I was just about to ask you the same, Senior."

"I wonder if you have ever seen a creature like this?"

Li Yao roughly described the appearance of the war chariot.

"This creature is known on the surface as an 'Unspeakable Thing.' It is more than a Hegemon-level..." Li Yao felt they might not know what a Hegemon was, so he corrected himself, "It is a creature even more terrifying than the Black Dragon God."

"I currently have no way to deal with it, and my accidental entry into the subterranean world was to escape its pursuit."

"Then the benefactor should just run!" Poppy’s heart was in turmoil. Even a benefactor more powerful than the Black Dragon God had creatures they couldn't deal with?

"I can't run," Li Yao said calmly. "It has been watching me from above the whole time."

"What?" Poppy’s small face turned deathly pale. She stood up and turned to look at Heimerdinger. "Senior, do you know about the war chariot the benefactor mentioned?"

"The benefactor saved our Bandle City; if you can, you must help him!"

"Poppy, sit down first."

"Being this impulsive doesn't look like you."

Heimerdinger frowned. "Li Yao, you should know that we are all Lower City people; we have never been to the surface in our entire lives."

"Even I have never heard of the 'war chariot' you speak of."

"But I have heard of an 'Unspeakable Thing'."

"Because several hundred years ago, it appeared in the subterranean world once."

"Oh?" Li Yao was somewhat surprised. "And how was it resolved in the end?"

If the Upper City people didn't show up, the Lower City people shouldn't have had the ability to kill a [Hunter].

"It was the Black Dragon God."

"It cost the lives of twelve Black Dragon Gods to completely eliminate that creature."

"That is also why, despite being a symbol of disaster, they are honored with the title of 'God'."

Twelve Hegemon-level creatures.

They certainly had the ability to kill a [Hunter].

Li Yao wore a look of doubt.

But why

would the Black Dragon Gods be willing to intervene?

Could it be that those Black Dragon Gods viewed the subterranean world as their own property and would not allow others to destroy it?

"Li Yao, I am very sorry, I cannot answer your question."

"But the Upper City people might know."

"Understood, I will go to the Upper City today."

Heimerdinger stood up and walked toward the bookshelf behind him.

He took out an ancient book covered in dust.

He blew on it hard, and a large amount of dust immediately filled the air.

"Cough, cough!"

"This is a record from that time; you can take a look."

"But before that, Li Yao, shall we make an agreement?" Heimerdinger looked at Li Yao earnestly.

"Please speak, Senior."

"After you go up, no matter what happens, please come back to the Lower City once within thirty natural days."

"I know this request is somewhat excessive; you may make any demand in return."

"Senior," Li Yao smiled and interrupted, "I know what you mean. I agree, and the time it takes me to come back down won't be as long as thirty days."

"As for a request, I do have one. I'll have to trouble you, Senior." Li Yao’s gaze shifted to the wreckage of parts in the center.

In the afternoon,

Li Yao stayed in Heimerdinger’s laboratory.

Heimerdinger went to the central square of Bandle City

to help upgrade the Silver Tree’s system,

and to help install a life-force detector on the Silver Tree.

Heimerdinger expressed that he was extremely happy to do so,

because he had long wanted to study this manned transport tool from above the surface,

and he promised to push the detector’s upper limit to the maximum!

At the very least, it wouldn't explode when encountering over-spec creatures.

Only then did Li Yao feel at ease, staying in the laboratory to study the ancient book Heimerdinger had left behind.

According to the senior,

this book was discovered in the forbidden zone of the Gloomy Labyrinth.

It might have been left behind by an Upper City person or placed there intentionally.

As for the agreement with the senior,

Li Yao had actually been suspicious for a long time.

These 'Upper City people' were a bit too strange.

They were all promoted from the Lower City to the Upper City.

For so many years,

(Little Master, there is more to this chapter, please click the next page to continue reading, it gets even more exciting!)

how could the people of the Lower City not see a single Upper City person?

The forbidden zone,

the 'curse' of the forbidden zone,

the Black Dragon Gods who helped deal with the [Hunter]—

all of these things

contained too many doubts.

Even if it weren't for the 'war chariot' matter, he would have to enter the so-called 'Upper City' to investigate!

Li Yao opened the ancient book

and flipped through it rapidly, reading ten lines at a glance.

The [Hunter] in the shape of an eyeball.

Yes, eyeball-shaped.

No eyelashes, no contours, no whites of the eyes.

Just a pure black sphere.

As for why it was called an 'eyeball',

it was because its ability was related to 'seeing'.

Anything the eyeball 'saw' would turn into black spots and vanish into thin air.

"That’s about the same as the destruction caused by the war chariot. Is there any connection?"

Looking at the description, it was even more destructive than the war chariot.

No,

it might not necessarily be as strong as the war chariot.

If it were truly 'die upon seeing',

those Black Dragon Gods—let alone twelve of them,

even a hundred, even ten thousand,

would not be able to resolve such a creature!

There was no description of the Black Dragons dealing with the [Eyeball] above;

there were only the [Eyeball]’s records of destruction.

In just two hours, it destroyed thirteen cities.

And after those two hours, it was intercepted by the Black Dragon God.

That was also the first time the Black Dragon God appeared.

In the eyes of the Lower City people, it was like a savior, crowned with the name of 'God'.

"'Die upon seeing'—"

"with this ability, destroying thirteen cities in two hours isn't actually that fast."

"Could it be related to speed?"

"Is the eyeball itself slow?"

"Or if the speed is fast to a certain degree, the eyeball’s dynamic vision cannot capture it, and thus it cannot destroy it?"

Li Yao pondered.

War chariot, eyeball.

The destruction methods of the two [Hunters] were the same.

It was very likely they were of similar strength and had similar methods of being killed.

After researching for a while longer,

Li Yao committed several possible ways the Black Dragon Gods could have won to memory.

If he didn't get the information in the Upper City, he could try these methods.

At the very least, there was some progress.

There were many books in Heimerdinger’s laboratory,

and he had promised Li Yao he could read them at will.

There was still some time before the [Promotion Battle].

Li Yao began to flip through them.

"The subterranean world is truly vast."

"The Lilliput Kingdom, to which Bandle City belongs, has seven cities of similar scale to Bandle City."

"And there are over a hundred countries like the Lilliput Kingdom in the entire subterranean world!"

"The overall scale of the Lilliput Kingdom is considered medium."

"Sixty years ago, the senior once estimated the population of Bandle City."

"Nine million Yordles."
