Starting Off Survival With A Small Treehouse

Chapter 1389 - 695: Weapon Capable of Creating Black Holes (Part 2)

Extremely high hardness, and a melting point that reaches billions of degrees.

She is very familiar with these physical properties; back then, they spent several years building the Crystal City.

At that time, the machinery used to construct the Crystal City was as large as a mountain, and it utilized the technology of alien invaders.

The fate of that machinery afterward is unclear; perhaps it was destroyed since it had the potential to threaten the Crystal City.

Having participated in the construction of the Crystal City, she knew well that relying on human technology alone, even with nuclear weapons, couldn’t destroy the Crystal City.

If there were a super close-range explosion, it would most likely just break this red crystal into scattered pieces, but to completely annihilate it...

It’s fair to say that relying solely on nuclear weapons is exceedingly difficult, almost impossible.

However, the weapon she brought from another dimension can compensate for this inadequacy.

As long as their nuclear weapons can shatter these red crystal fragments, the weapons she brought from another world can clean up the aftermath.

"Let’s wait here." Xu Ying led Xu Xin to the far edge.

"Ying." Keke nestled in Xu Xin’s arms, looking toward a location not too far away.

Keke was looking at the edge of this hollow area, just less than twenty meters away from them.

There, three vine sphere elevators stood.

At the moment, they are all tightly closed, completely enveloped by vines.

"If any alien invaders enter later, we’ll slip in with them." Xu Ying whispered.

"Yingying, regarding your hypothesis, I have a question." Xu Xin spoke softly.

"Hmm? What question?"

"If this concentrated red crystal is so hard and strong, how do alien invaders use it as the Source of Life?"

According to what the monsters said, these red crystals are meant to be consumed.

So hard, how can they be eaten?

"Just swallow them whole." Xu Ying pursed her lips, "Why do you think they cut these red crystals into fingernail-sized pieces?"

"...So, alien invaders can digest small pieces of concentrated red crystals?"

"These red crystals are basically ’food’ for their species. Concentrated red crystals are probably like... compressed biscuits?" Xu Ying speculated.

Compressed biscuits...

"The alien invaders’ ’stomach acid’ must be really strong then..."

"It’s not necessarily that they’re strong; it might just be that fingernail-sized red crystal pieces are too small, the energy within is too little, having lost some properties of the larger red crystals." Xu Ying guessed.

"Does Earth’s white-transparent crystals have similar properties?" Xu Xin asked.

"I’m not sure about that." Xu Ying shook her head, "We never cut Earth’s white-transparent crystals into such small, fragmented pieces. It’s just a guess."

Xu Ying’s speculation is not unwarranted.

Previously, the fist-sized pieces of concentrated red crystals they obtained could drive alien invaders mad.

But the fingernail-sized ones did not.

"So, we have to... use the weapon you brought?" Xu Xin’s voice slightly lowered.

If that were true...

He looked at Xu Ying.

If it were true, Yingying then only had a few hours left.

What does a person generally do in the last few hours of their life?

Xu Ying’s choice was...

"I’m just trying to resist a little..." Xu Ying bit her lip and said.

Her choice was to struggle a little longer.

In the underground space amidst the Red Mist she spent a few hours dwelling on this issue.

But she kept waiting below due to fear of danger.

Yet, the longer she waited, the more fear haunted her heart.

A feeling of... life slipping away, little by little, without a purpose.

Moreover, in these hours, there was never any danger below.

Finally, upon seeing Zhao Xiaochuan finish his excavation, Xu Ying couldn’t sit still any longer.

She decided to make one last effort.

She really didn’t want to die yet.

With her unstable situation now, using weapons from another realm would undoubtedly cause her to be erased by the world like her predecessors.

At least... she wished to see the world after driving the aliens away before she died.

This was also her brother’s wish, the Xu Xin from another space entrusted in her.

Therefore, she decided to infiltrate inside the World Tree to seek the hidden weapon of the alien invaders.

If she could find a weapon matching the effectiveness of the one she brought from another realm, she wouldn’t have to be erased by the world.

Xu Xin ultimately decided to join her.

He possessed the ability to identify and directly view valuable materials, and there was a little fellow in his arms who inexplicably knew some key information.

If they were to search for some crucial weaponry, coming along would undoubtedly be twice as effective.

But...

Xu Xin glanced at Xu Ying, who was already sitting on the ground hugging her legs.

He didn’t wish to discourage Xu Ying, but he believed, within this World Tree, there might be the weapon she wished for.

Especially in the residential areas above.

It’s likely weapons carrying is forbidden there.

How could such super weapons be placed there?

Xu Xin glanced around: "These weapons, aren’t they suitable?"

Around them, strange weapon setups stood at the ready.

Simultaneously, thousands of blinking eyes watched from all directions, like waves.
