Starting Off Survival With A Small Treehouse

Chapter 866: Chapter 516: Future... Farewell (5,500 Words)

In the image, Xu Xin continued speaking: ”Besides, I have also left behind a team of giant beasts that you will have to discover yourself; maybe you’ve already encountered them? Rest assured, you are not fighting alone.”

”Of course, I have instructed them not to help too much until you’ve grown, otherwise...” The image of Xu Xin smiled, ”I’m the one who knows you best, without challenges, you’ll become useless.”

”Some things I’m not convenient to talk about right now, nor do I have time to elaborate. If you encounter them, you might get some news from their side.”

”Those giant beasts are highly intelligent, communicating with them is completely possible.”

Xu Xin showed a look of realization.

On the ground, he encountered the giant crocodile, underground, he encountered that pitch-black giant beetle, Blood Patterned Python, and the soft giant insect suppressed under the prison.

These giant beasts have more or less provided him some help, and from the inner voices of the python and insect, he could further confirm that they know him.

So this was the case...

They were all teams left by the image of this self?

Suddenly, he felt a surge of confidence!

”Besides these, we also left behind the most precious legacy for you in the future.”

At this moment, the image of Xu Xin spoke again, with a smile for the first time revealing an expression of absolute certainty.

”And that is... the city you are currently in!”

”This city, crafted from extraordinary crystal!”

As he spoke, he walked to the window on the third floor of the palace, reaching out to point outside.

Although now it should be in a virtual image, Xu Xin could still see the city outside emitting a radiant white glow.

”This city will be our strongest weapon to change the future and save the fate of Earth’s life!”

This city was indeed built by this image of himself!

This crystal-like dream city, is it left for them?

”This city is not small, you should deeply experience it.” The image of Xu Xin laughed.

”The city’s area is a standard square, with a side length of five kilometers, covering twenty-five square kilometers.”

For a city area, this is quite large.

Building such a Crystal City is definitely not an easy task.

Not to mention the materials are incredibly hard!

”The materials of this city were excavated together with the beast bloodline, deeply buried in Earth’s ancient mysterious materials, complementing the beast bloodline.”

”This material is indestructible, incredibly hard, shaping these materials requires extremely complex methods; under ordinary conditions, physical impact is ineffective, requiring at least billions of degrees of high temperature to soften it.”

... How much?

Billions... billions of degrees of temperature?!

Xu Xin was a bit stunned.

This temperature is somewhat too outrageous?

The temperature at the core of the sun is only about 15 million degrees Celsius...

Of course, this temperature cannot be considered unattainable.

Moreover, it has been achieved in past Earth.

Controlled nuclear fusion.

Although the temperature of the core of the sun is only 15 million degrees Celsius, to achieve controlled nuclear fusion on Earth, creating an artificial mini-sun, the temperature of the plasma in the fusion device needs to be maintained above a hundred million degrees.

Controlled nuclear fusion experimental devices on the past Earth have long reached billions of degrees Celsius.

Of course, it’s just an experimental device; controlled nuclear fusion at the time was merely a high-investment, hopeful future prospect.

Some pessimists even believe that the difficulty for humanity to achieve true controlled nuclear fusion is comparable to achieving immortality.

However, with this technology possessed by the image of Xu Xin, he was not surprised.

After all, the image of himself seems to have almost achieved immortality...

Moreover, one of the uses of controlled nuclear fusion is having virtually endless energy, allowing exploration in deep space; in this sense, those alien invaders might already possess this technology.

But... using billions of degrees of high temperature to melt this crystal material and build the entire city...

This difficulty is perhaps far greater than controlled nuclear fusion?

... Terrifying.

What kind of substance is this?

How did they accomplish it?

”I cannot disclose the method of melting; perhaps you will encounter it later.” The image of Xu Xin spoke, ”You only need to know that this city can protect you from most attacks.”

”Indeed!” Beside him, Xu Ying couldn’t help but speak, ”It is true; we have already tested this city, shells, laser weapons, they cause no damage to it, they can even reflect laser weapons!”

Saying this, she hit the crystal table in front of her: ”This thing is incredibly hard!”

The image of Xu Xin nodded and continued: ”This is not the most important function.”

”As long as a creature has the beast bloodline, in this city, injuries and negative effects will gradually heal, and the beast bloodline will further strengthen to resist the erosion of the Blood Pattern mutation. In other words, any creature with beast bloodline in this city, will be in their best, strongest state... becoming your companion.”

This...

Xu Xin took a deep breath.
