I collect gold fingers in the heavens

Chapter 471
Wu Siyuan was wearing a spacesuit, so he didn't have to worry about ventilation, so he went straight in.

The cave is deep and deep, but this [Lava Pipe] is very spacious, it can accommodate dozens of people at the same time and walk on foot, winding and straight to the ground.

Although there was not much light inside, Wu Siyuan walked as if walking leisurely.

Walked all the way for about twelve minutes and forty-five seconds.

Wu Siyuan's eyes suddenly opened up, and a huge underground space appeared.

The highest point is [-] meters.

The widest point is [-] meters.

The longest point is four or five kilometers.

In fact, this is also a [Lava Pipe].

The width of lava tubes on the earth is generally between 14-15 meters, but most of the tubes are far from that large, and the depth is generally 1-15 meters underground.But this pipeline may be very long, maybe 18 kilometers or even more.Lava tubes are actually a very complex network.

The lava tubes on Mars are at least 80 times larger than those on Earth, and their diameters are generally between 40-400m.

At the end of the underground space where Wu Siyuan is located, there are many slightly smaller passages—of course, smaller than this underground space—these passages lead to deeper underground spaces.

However, under Wu Siyuan's intentional control, these passages have long been covered and sealed by the vibrating gravel.

Although the lava tube is an ideal place for humans to live after landing on Mars, in fact, its interior is very steep and the stones are very sharp, which poses great challenges to the subsequent development of humans.

Of course, if humans were able to land on Mars on a large scale at that time, this would certainly not be a big problem.

Wu Siyuan has a way to solve this problem.

Of course, there is no need for this.

He looked around the empty and dark cave-like 【Lava Pipeline】.

From the perception of [Pulse of the Earth], this [Lava Pipeline] is strong enough.

So Wu Siyuan started the show operation.

With a wave of his hand, a large amount of Martian soil mixed with space soil flew out of [Shennongjiao Space], covering the entire underground space, almost one meter high.

What the original owner Mark Watney could do with a lot of physical effort, Wu Siyuan managed with just a few thoughts.

Then Wu Siyuan summoned [Vitality Tree Ent]!
[Ent] is another name for the tree shepherd in the world of "Boiling Beast Blood".

The [Vital Energy Tree] came from the world of "Tree Zong", and it was the first generation of the child tree of the mother tree in the original world. Later, Wu Siyuan left the novel world of "Tree Zong" and took this sub-tree with him.

With the help of the original [Ancient War Tree Ent] in [Shennongjiao Space], transform it into a white tree shepherd.

A white tree shepherd hundreds of meters high.

After Wu Siyuan summoned it, it almost reached the top rock wall.

After it came out, it obeyed Wu Siyuan's instructions and displayed its innate ability - to take root on the ground.

It broke off many of its beards and threw them on the soil in the underground space. Immediately, three plants that were very similar to the [Vitality Tree] grew at a speed visible to the naked eye, and quickly grew to tens of meters high.

These spawned [Vital Energy Sub-trees] only exist for one year, but they still have the ability to convert absorbed sunlight and other energy into vitality, but the area covered is only about 10 mu.

Of course, this is enough!

The white tree shepherd nodded from Wu Siyuan, and Wu Siyuan took it into [Shennongjiao space].

Then he looked up at the top of his head.

【Vital energy subtree】 is to absorb sunlight and other energy and transform it into substances such as 【Aura】.

Now in the ground, there is no energy source, no way.

With a thought, Wu Siyuan activated the [Pulse of the Earth] ability again.

Since his abilities in many fields have been improved, he has become more and more comfortable with abilities like [Pulse of the Earth].

Of course, because he doesn't use his own body, a body without a foundation will cause quite serious damage after using these abilities many times and frequently.

Therefore, Wu Siyuan usually doesn't need it if he can.

I saw that the rock wall above the head was suddenly blasted at a fixed point, blasting out many small skylights, and sunlight and radiation followed.

【Vital Qi Zishu】sensed the sunlight, its branches and leaves immediately swayed, wisps of sunlight and carbon dioxide were absorbed by its unique 【Yebai body】, and then transformed slowly.

In the entire crypt, faint vitality fluctuations also began to appear, which is the so-called aura fluctuations.

A faint smile appeared on Wu Siyuan's pale face.

He was right in predicting that [Vitality Tree] really could withstand the harsh climate of Mars and survive.

But water is a problem!
Plants need water to survive, even the 【Vital Qi Sub-Tree】is the same.

Is there water on Mars?
Of course there is water on Mars!
However, this water is mainly distributed at the poles and exists in solid form.

In addition, deep underground on Mars, there may also be a large amount of salty water.

It has been detected before that there is a seasonal striped landform on Mars.

The new findings show that these streaks are likely related to groundwater from the deeper subsurface of Mars.

These streaks on Mars only appear on certain mountainsides and only during the warmest part of the year.Scientists previously thought that these streaks were formed by salty water flowing on the surface of Mars or in shallow layers of Mars.

But recently, some scientists from the University of Southern California and NASA's Jet Propulsion Laboratory believe that the water may come from the deep underground of Mars, and they reach the surface of Mars along the cracks in the ground under the action of pressure.The source of these groundwater is about 750 meters below the surface of Mars.

By analyzing images taken by the Mars Reconnaissance Orbiter, the researchers found a spatial correlation between the streaks, stratigraphic structures, and impact faults.There are multiple clues that the stripes may have come from salty water buried deep beneath the surface of Mars.When the winter on Mars comes, the salty water gushing out of the surface will freeze in the ascending channel; and when the summer on Mars comes, the water will thaw again.

If this is the case, then Mars' deep groundwater system may be even larger than previously thought.Last year, the European Space Agency's Mars Express probe discovered near the south pole of Mars that there may be a huge underground lake.But evidence for the existence of aquifers at lower latitudes has so far been lacking.

This inference is not conclusive.Many scientists have different opinions on these strange stripes on Mars.For example, some scientists believe that these streaks have nothing to do with liquid water, they are just landslides.

Scientists can't be on the front line to detect, so they can only analyze and guess the existing data, and Wu Siyuan has a chance to prove this guess in person.

He ordered several [Vitality Trees] with his mind to expand the roots as deep as possible into the ground, looking for the source of water for life!
While giving the order, Wu Siyuan took out three balls of water exuding rich aura and vitality from the [Shennongjiao Space], and hit the roots of the three [Vital Energy Trees].

This will be the source of strength to support the expansion of [Vital Energy Subtree].

Wu Siyuan looked at the three [Vitality Trees] quietly for a while, then turned around and left the underground space, returning to the ground.

His next task is to dig out the [Pathfinder] buried under the yellow sand.

In this way, Wu Siyuan can re-establish contact with the earth at the right time and tell them the great discovery on Mars.
