Chapter 5 Vitality Sub-Tree

Wu Siyuan was wearing a spacesuit, so he didn't have to worry about ventilation issues and walked straight in.

The cave is deep, but this [lava tube] is very spacious and can accommodate dozens of people walking side by side at the same time, twisting and turning, leading directly to the underground.

Although there was not much light inside, Wu Siyuan walked as if he was strolling in a leisurely courtyard.

The journey took about twelve minutes and forty-five seconds.

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

The highest point is one hundred and thirty meters.

The widest point is 360 meters.

The longest point is four or five kilometers.

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

The width of lava tubes on Earth is generally between 14-15 meters, but most pipes 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 and 400.

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

However, under Wu Siyuan's deliberate control, these passage openings had long been covered and sealed by the shaking gravel.

Although the lava tube is an ideal place for humans to live after landing on Mars, the interior of the lava tube is actually very steep and the rocks are very sharp, which poses a great challenge to subsequent development of humans.

Of course, if humans can land on Mars on a large scale by then, this will certainly not be a big problem.

Wu Siyuan even has a way to solve this problem.

Of course, this is not necessary.

He looked around at the entire empty and dark cave-like [Lava Tube].

From the perception of [Pulsation of the Earth], this [Lava Pipe] is strong enough.

So Wu Siyuan started the show operation.

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

What the original owner Mark Watney spent a lot of energy to do, Wu Siyuan did it with just a few thoughts.

Then Wu Siyuan summoned [Vitality Tree Ent]!

[Ent] is the nickname of the tree herder in the world of "Beast Blood Boils".

The [Vitality Tree] comes from the world of "Tree Sect" and is the first-generation sub-tree of the original world mother tree. Later, Wu Siyuan left the "Tree Sect" novel world and took this sub-tree with him.

With the help of the power 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 of the rock wall.

After it came out, it followed Wu Siyuan's instructions and used its innate ability to take root.

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 [Yuanqi Subtree] grew at a speed visible to the naked eye, and soon grew to tens of meters. high.

These [Vitality Sub-Trees] only exist for one year, but they still have the ability to convert absorbed sunlight and other energy into vitality, but they only cover an area of ​​about 100,000 acres.

Of course, this is enough!

The white tree shepherd nodded from Wu Siyuan, and Wu Siyuan put it into the [Shennong Corner Space].

Then he looked up overhead.

[Vitality Sub-Tree] absorbs energy such as sunlight and converts it into substances such as [Aura].

Now in the underground, there is no energy source, no.

Wu Siyuan thought and 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 such as [Pulse of the Earth].

Of course, because he is not using his own body, his body without foundation will cause quite serious damage after using these powers many times and frequently.

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

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

After the [Yuanqi tree] sensed the sunlight, its branches and leaves immediately swayed, and wisps of sunlight and carbon dioxide were absorbed by its unique [leaf white body], and then slowly transformed.

Throughout the crypt, faint fluctuations of vitality, also known as spiritual energy fluctuations, began to appear.

Wu Siyuan's pale face revealed a faint smile.

He was right in his prediction. The [Vitality Tree] could withstand the harsh climate of Mars and survive.

But water is a problem!

Plants need water to survive, even the [Vitality Tree] spawned.

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

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

New findings suggest the streaks are likely related to groundwater coming from deeper underground on Mars.

These stripes on Mars appear only on certain hillsides on Mars, and only during the planet's warmest times of the year. Scientists previously thought the streaks were formed by salty water flowing on the surface or in the planet's shallow formations.

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

By analyzing photos taken by the Mars Reconnaissance Orbiter, researchers found a spatial correlation between 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. Whenever winter comes on Mars, the salty water that emerges from the surface will freeze in the ascending channels; and whenever summer comes on Mars, this water will thaw again.

If this is indeed 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 that a huge underground lake may exist near the south pole of Mars. But evidence for the existence of aquifers at low latitudes has so far been lacking.

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

Scientists cannot be on the front line for detection, so they can only analyze and speculate on the existing data. Wu Siyuan has a chance to prove this guess in person.

He ordered several [Vitality Trees] with his mind to extend their roots as deep into the ground as possible, looking for the source of life's water!

While giving the order, Wu Siyuan took out three water sources exuding rich spiritual energy from the [Shennong Corner Space] and struck them deep into the roots of the three [Vital Energy Trees].

This will be the source of power to support the expansion of [Vitality Sub-Tree].

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

His next mission 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 about the great discovery on Mars.
