I collect gold fingers in the heavens

Chapter 470 Lava Channel
Some of its characteristics are also very suitable for the environment on Mars.

If it is used well, Wu Siyuan will have a great possibility to build a real prototype of a city shell on Mars.

That thing is [lychet]!
[Lijiao], produced in the world of "The Beast's Blood Boiling", the [Liping tree] that grows in the devil world.

This [lychee tree] looks like a pot-bellied bottle, and the variety in Daban Town is the best. One tree can harvest 1755 mocha of [lychet], which is about [-] catties of [lychet]!
This [lijiao] has amazing adhesive properties, and things that stick together are stronger than things that are welded.

In the world of "Boiling Beast Blood", the hero Liu Zhenzhen once used all his strength to break off the handle of a chair glued with [lijiao].

Obviously, there were traces of two pieces of wooden rails sticking together on the stubble of the chair handle, but the upper end was twisted off, and the lower end was still not separated.

You must know that the male protagonist Liu Zhenzhen at that time was able to wrestle with the giant's wrist, but that was the case, and he couldn't separate the joints. It is conceivable how strong the adhesion is, even if it is the most adhesive. Cement, in front of this kind of [lijiao], can only be regarded as a little brother.

However, this overlord-type super glue has not been widely used in the devil world because it is afraid of water.

【Lijiao】It is not afraid of fire, not afraid of strong break, but it cannot moisturize for a long time.

After being soaked in water for a long time, this [Lijiao] loses its adhesive ability.

Also because of this obvious shortcoming, the application scenarios of this thing are very limited.

Wu Siyuan returned to the real world, because of this characteristic of [Lijiao], he never took it out.

In the original novel, the hero Liu Zhenzhen applied it in desert areas and underground spaces.

But after coming to Mars, Wu Siyuan discovered that [Lyjiao] is also useful.

Of course, before that, Wu Siyuan needs to plant [Lyping Tree] on Mars.

In order to obtain enough food to survive for four years, the male protagonist in "The Martian" chose to grow potatoes.

And Wu Siyuan, in order to obtain the adhesive materials for building the city, planned to plant [lychet tree].

The two sides plant different species and have different purposes, but they have one thing in common—the planting process is quite difficult.

The original owner, Mark Watney, can transform the habitat into a space farm, but it is no problem to grow potatoes in this way, but it is a big problem to plant [lychee], a plant with a well-developed root system.

[Lypin tree] can only be planted outside the habitat, facing the harsh environment of Mars.

The first is the temperature issue.

The average temperature on Mars is about minus 60 degrees Celsius.

In winter, near the poles of Mars, temperatures can drop as low as minus 125 degrees Celsius.

In the summer on Mars, the temperature near the equator can reach 20 degrees Celsius, but at night, the temperature can plummet to minus 73 degrees Celsius.

With such a harsh temperature, it is no wonder that once Mark Watney's space farm burst, all the potato seedlings were frozen into popsicles, which shattered when touched.

But the biggest difficulty is not this.

Instead, the carefully cared-for microorganisms in the space farm were all exposed to the harsh environment of Mars and were frozen to death!

So far, the hero in the movie can no longer obtain a stable source of food through planting, forcing Mark Watney to think about making a living again.

[Lyping tree] Planted directly on Mars, not to mention it can't stand it, even the microbes can't stand it!

So before Wu Siyuan planted [Lyping Tree], he had to find a place where it could be isolated from the temperature.

If you are on Earth, you can do this by building a dome-like shield cabin.

But here is Mars.

When Wu Siyuan called to place an order on Earth, it would take at least four years before he received it.

But with all his plans, Wu Siyuan estimates that he can only stay in this world for two or three years, and this time-traveling journey will end with the end of the movie.

What's more, Wu Siyuan can't call back to Earth now.

The [Pathfinder] that can communicate with the earth for a short time is still buried in the yellow sand, and Wu Siyuan has no intention of digging it out.

He didn't want to be exposed to US satellite surveillance so soon.

Fortunately, there is no way to customize a special dome shield from the earth, but Wu Siyuan can still solve the living environment problem of [Lyping Tree].

Dig a hole!

To be precise, it is to use the [lava pipeline] on Mars!
This is a natural sanctuary on Mars!

Like the earth, Mars also has geological movements and volcanic eruptions.

After a volcanic eruption, not only will it leave a ferocious crater on the surface, but sometimes lava pipes will spread out around the crater during the formation process.

During the flow of high-temperature, low-viscosity lava, the outer surface cools quickly to form a solid hard shell. Under the heat preservation effect of this hard shell, the internal lava will continue to flow until the lava stops flowing.

After the lava in the hard shell is emptied, tube-shaped caves are formed, which are lava pipes.

These lava pipes are hidden deep underground on Mars. In the future, when people come to Mars, they don’t need to spend a lot of materials to build a protective wall. The thick rock formations of the pipes can resist radiation, sandstorms, meteorites and other disasters.

Not only that, because the gravity of Mars is only equivalent to 38% of the gravity of the earth, the lava pipeline on Mars is also wider than that on the earth-the lava pipeline on the earth is 15 meters wide, while the width on Mars can exceed 160 meters. Sufficient for human habitation, it is simply a natural refuge.

This was originally a place for future Mars colonization plans envisioned by Earth scientists.

But now, Wu Siyuan plans to transform these lava pipes, which may be 160 meters wide, as his planting base.

First, Wu Siyuan had to find the nearest lava pipeline.

Human beings search for holes and paths leading to underground lava pipelines on Mars through detectors and rovers.

This is time-consuming and labor-intensive.

But for Wu Siyuan, there is no such trouble!

He sat in the habitat, closed his eyes, thought penetrated the habitat, entered the ground, and felt the [pulse of the earth]!
This is his innate ability obtained and solidified in another world.

"I found it..." It didn't take long for Wu Siyuan to smile.

With a thought in his mind, the ground one kilometer away from the habitat suddenly exploded, revealing a hole the size of two people.

The inside of the cave is deep, like the entrance to hell.

Wu Siyuan closed his eyes in satisfaction and fell asleep on Mars.

the next day.
Wu Siyuan put on a light space suit, sat in the rover, and headed for the entrance of the cave that was blasted last night.

If the rover is fully charged, it can travel 35 kilometers.

The distance of one kilometer is just a stroll for it.

Wu Siyuan did not intend to go to the impact crater 3200 kilometers away.

after an hour.

Wu Siyuan came to the entrance of the cave that he made by himself very smoothly.
