Doomsday: I can become stronger by killing the Virgin

To be honest, Ye Hao never thought that human beings could be above all life.

If it is said that these lizardmen slaughter humans just for food, then Ye Hao thinks it is understandable, after all, the law of the jungle is already there.

However, this lizard man made a mess of human civilization not for eating, but for taking back his so-called homeland, which Ye Hao could not accept.

And from Ye Hao's point of view, these so-called lizardmen are not as powerful as imagined, perhaps for ordinary people, they are indeed difficult to defeat, but in Ye Hao's view, these tricks and methods are just like children.

With the information obtained through the ability of the human world, Ye Hao only knows the hiding place of this group of lizardmen, which is underground!
"It seems that I really have to go to the underground world."

But after all, Ye Hao did not go down hastily. After all, the underground world does not have the rich oxygen on the surface. Moreover, through the memory of the lizardman just now, Ye Hao only knew that the underground world was much bigger than he imagined.

Although it doesn't have everything like Journey to the Center of the Earth, it is indeed intricate.

And those lizardmen are no different from the one Ye Hao killed, and they have some special abilities more or less, which is what Ye Hao is worried about!
Ye Hao is absolutely sure to kill one lizardman, but what if there are hundreds or thousands of them?
However, Ye Hao also couldn't figure out one thing, that is why such a powerful lizard man has not appeared in the human world for such a long time, but has been living underground?

"System, do you know the secrets about these lizardmen?"

Helpless, Ye Hao finally decided to turn to the system for help, but he forgot what kind of sixth child his system was.

【Ding!Host, I know! 】

I only heard the system in my head happily answering Ye Hao's question, and then it didn't make a sound again.
"Uh, you know you're just talking!"

【Ding!The host just asked the system if he knew it, and didn't ask the system to explain it in detail! 】

"Wow! What you said makes sense!"

However, Ye Hao naturally knew what his system wanted, so he asked with a smirk, "I'll give you 1000 points, tell me about it?"

【Of course, 1000 points have been deducted! 】

[Host, the underground world is the territory of Zhilong, that is, those lizardmen mentioned by the host. These lizardmen have been affected by geothermal radiation all year round and have formed indestructible skin. The reason why they no longer move on the surface is because they have adapted The low oxygen concentration life in the underground world. 】

[The remaining 2000 words, you need to continue to pay points to unlock it. 】

Hearing the system's words, Ye Hao almost didn't take it directly.

Good guy, I spent 1000 points as a co-author, but I only bought a trial version!

"System, just tell me, how many points do you need to tell me all of them?"

Facing Ye Hao's gnashing of teeth to ask questions, the system in his mind remained calm.

【Ding!Please don't worry the host, you only need [-] points to unlock all the information about Zhilong. This system hereby solemnly promises that this is a one-time buyout, and there is no need to pay any fees in the future! 】

Hearing the system's voice as if a ruse had succeeded, Ye Hao had completely surrendered to his old sixth system.

"I said the system, what do you want my points for? Why do you feel like I need points every time I call you to do something?"

【Ding!Host, you need to understand the truth of working with money! 】

The system's rebuttal left Ye Hao speechless, helpless, whoever let himself really not know the mysteries of the underground world, he could only smash his teeth and swallow it in his stomach, spending 20000 points with tears in his eyes.

[Points deducted successfully!Let's start unlocking premium content! 】

I have to say that Ye Hao's system is still very reliable, as long as you have enough points, it is like a master to it.

[As an intelligent species evolved from dinosaurs, Zhilong not only has a strong physical body, but also has the mental ability to manipulate objects, and many even have stronger strength.]

"I have to say, this world is really amazing."

After listening to the system's introduction about Zhilong, Ye Hao fully understood why Zhilong, who is so powerful in all aspects, never came to the surface to compete with humans for territory. It turned out that they were afraid of oxygen!
Since the oxygen on the surface has now changed from 13% to 21%, once these lizardmen appear on the surface, a situation similar to human drunkenness will soon appear.

As for the lizardman that Ye Hao killed, it was naturally affected by the oxygen that made him lose so quickly. What's more, even that lizardman seemed to be forced out by himself.

"However. It seems that I can't go down like this."

Since these lizards can't exist on the surface for a long time, Ye Hao also suddenly found that he can't go to the underground world to catch those lizardmen!
After all, if you go down, you will be hypoxic immediately, and you will have symptoms similar to altitude sickness.

【Ding!What if the host is in trouble?Come to the Points Mall to have a look! 】

"You pick your time."

Facing the system that sounded in his mind in time, Ye Hao couldn't help feeling helpless.

Who makes himself want it?
"Okay, let me see what's new in your points mall!"

Ye Hao didn't have ink marks this time either, so he directly clicked on the points mall to browse, and soon he found that a series of products were launched in the mall for the situation he was facing now!

[Turtle Breath Pill: 50 Points]

[Introduction: The elixir made with reference to the turtle's way of life, can slow down your heartbeat and blood flow within 24 hours after taking it, and adapt to the low-oxygen environment, but at the same time, it will also have the side effect of slow response. 】

"Eh, cheap is not good"

Seeing this introduction to Guixi Pill, Ye Hao was dumbfounded, he really didn't understand what the system was doing?

Test yourself as the host?

Has anyone tested the host with this thing?

"Next next."

Ye Hao directly turned to the products whose unit price starts with ten thousand, and at this time he also found some products that satisfied him.

[Special Ability: Survival of the Fittest]

【10 million points】

[Introduction: After using it, you can get a special ability—survival of the fittest. Using this ability, you can adapt your body to any environment of Blue Star. 】

Seeing the introduction about this ability, Ye Hao bought it without any hesitation with a wave of his hand!
[Congratulations to the host for successfully obtaining the ability: Survival of the fittest! 】

"Oh, I really convinced you, the sixth child."

Hearing the voice in his head, Ye Hao couldn't help but sighed.

After all, he heard a hint of joy in the voice of his own system.
