I collect gold fingers in the heavens

Chapter 472 The Evolved Lychee Tree
Mars has almost no magnetic field. The atmosphere of Mars contains 95.97% carbon dioxide. It is basically difficult for plants on Earth to survive here.

Plants need water and access to various nutrients, as well as a mixture of nitrogen, oxygen, carbon (in various forms), and other "air components" to thrive.Plus a stable range of light waves (from different spectra) and a relatively stable temperature to promote photosynthesis and reproduction.

The soil on Mars contains a lot of toxic substances and does not have the nutrients needed by plants.

Also, the atmospheric pressure on Mars is less than [-] percent of Earth's sea level pressure, and the temperature, so any plant you place on the surface of Mars will suffocate, of course, it will probably suffer from a large number of cells first Rupture and pressure loss dehydration to death.

Therefore, under normal circumstances, if you want to grow plants on Mars, you need to build a Mars farm that is isolated from the Martian air and pressurized, just like what the hero Mark Watney did in his habitat.

However, the [Vital Energy Tree] that Wu Siyuan took out was not an ordinary plant.

There was a faint fluorescence on its body, which resisted the pressure of Mars and survived tenaciously.

If botanists on earth see it, they will exclaim that this is a miracle of life.

And the person who made this miracle was using a rover to drag a machine covered in dust and wind and sand back to the habitat.

This is the [-]th day since Wu Siyuan came to this world.

It is also the forty-eighth day that the hero Mark Watney stayed on Mars.

This dusty and sandy machine is the Mars rover that successfully landed on July 1997, 07. It is the first Mars rover that humans have landed on Mars in the true sense—Pathfinder!

Mars Pathfinder consists of an orbiter, lander and the Sojourner rover.

The total weight is 800 kg, of which the lander weighs 264 kg.

旅居者号火星车，是一辆长0.66米、宽0.48米、高0.30米、重11.5千克的6轮车。

It carries a camera.

Its last transmission to Earth occurred on September 1997, 9, when the sojourner had been on Mars for nearly four months -- 27 times its designed lifespan.

Finally, it was covered by the wind and sand of Mars in the Arsidaria Plain.

In the original movie, the hero Mark Watney dug it out and then got in touch with the earth.

Wu Siyuan will also get in touch with the earth, but not now, so after he brought the Mars rover back, he threw it aside, and then went to the entrance of the lava pipeline one kilometer away.

an hour.

Wu Siyuan came to that underground space.

Those three [Vital Energy Trees] are thriving.

Each plant is at least thirty or forty meters high.

The canopy formed by white leaves almost covered the top of the entire underground space.

【Vital Energy Subtree】absorbs sunlight and carbon dioxide, undergoes a special reaction, and releases vitality and oxygen.

Although he was wearing a spacesuit, Wu Siyuan could feel that the composition of the air in the entire underground space had changed.

The proportion of oxygen has increased and the proportion of carbon dioxide has decreased.

However, the air pressure did not change much.

Therefore, people on earth still cannot breathe the air here freely.

Wu Siyuan stroked the trunk of the [Vitality Tree] with his hands, and his spirit continued to spread downwards along with the trunk. He saw the intertwined roots under the soil, deeply rooted into the rock, extending down for thousands of meters, and plunging into the deep water of Mars. In his veins, he frantically absorbs salt water and transforms it into his own source of life.

He immediately understood that in the next year, he didn't need to worry about the survival of these three [Vital Energy Trees].

Of course, Wu Siyuan also knows that it is impossible to completely change the environment of Mars and make it suitable for the survival of humans on Earth by relying on these three [Vital Qi Sub-trees].

Of course, Wu Siyuan's purpose is not the same.

Because there is enough vitality in the underground space, it basically satisfies the growth conditions of [Lyping Tree].

Wu Siyuan took out the seeds of the [Liping Tree] from the [Shennongjiao Space], dropped them into the fertile Martian soil, and then took out a drop of [Fountain of Life] and dropped them on it.

Immediately, the [Lipping Tree] took root and sprouted, and grew into a large bottle tree with a height of seven or eight meters at a speed visible to the naked eye. It bloomed, but had no fruit, and soon could not withstand the low pressure of Mars, lost water, and directly withered, lost its vitality.

Wu Siyuan froze for a moment, and immediately realized the problem.

Because there are no insects such as bees to pollinate, the [Lipping Tree] can only bloom but not bear fruit.

Wu Siyuan, who wanted to understand this, disposed of the withered [Lyping Tree], took out the seeds of [Lyping Tree] from [Shennongjiao Space] again, and used the [Fountain of Life].

Another big bottle tree grew vigorously at a speed visible to the naked eye, and bloomed.

At this moment, Wu Siyuan, who had been prepared for a long time, started artificial pollination with mental strength.

This speed is very fast.

In just a few seconds, [Lyping Tree] grew black fruits.

Not long after, the effect of [Fountain of Life] dissipated, and [Lyping Tree] lost its vitality again due to the low pressure of Mars.

Wu Siyuan was not discouraged, and continued to use the seeds from the fruit of the [Lyping Tree] grown on Mars to plant, watered it with the [Fountain of Life], pollinated it artificially, and harvested the fruit.

Wu Siyuan repeated this operation again and again, ten times, twenty times, fifty times... like a robot that doesn't know how to get tired.

Yes, Wu Siyuan used the evolutionary instinct of plants to adapt to the environment, and used the [Fountain of Life] to shorten the evolution time by tens of millions of times, reaching the evolutionary result that only appeared in history for tens of millions of years.

Wu Siyuan wants to cultivate a plant suitable for the low-pressure environment of Mars.

[Vitality Zishu] This kind of thing doesn't count.

This is not an easy thing to do.

Wu Siyuan had been busy for a whole day, but failed. He calmly returned to the habitat to rest.

Continue the next day.

Continue on day three.

Day [-]...

until the sixth day.

The thirty-sixth day since Wu Siyuan came to this world.

It was also the fifty-fourth day that the hero Mark Watney stayed on Mars.

A low, pot-bellied bottle tree with loose leaves and spongy tissue appeared in front of Wu Siyuan. Its roots penetrated into the roots of the [Vitality Tree], obtaining the nutrients needed for growth from it.

Although there are still many restrictions, this is indeed a milestone achievement——

A plant that can grow in a Martian environment!
The corners of Wu Siyuan's mouth couldn't help but rise. He collected a large number of seeds of this evolved [Lipping Tree], planted them in every corner of the underground space, and then dripped them with the [Fountain of Life].

One after another [Lypin Tree] rose from the ground and grew into a pot-bellied bottle tree with a height of only two or three meters.

"The bait is ready! It can be thrown into the fish pond!" Wu Siyuan's eyes were placed on the Mars rover outside the habitat cabin.

At this time, on Earth, some people have also discovered the anomaly on Mars!
