According to the information Su Mo had gathered so far— 

After killing a monster in the wilderness, the rarity of the reward started with wooden treasure chests being the most common, followed by iron treasure chests, copper treasure chests, and so forth.

Many people speculated that there were treasure chests of silver, gold, and diamond, but based on what Su Mo had learned on the first day yesterday, the best treasure chest opened so far was only a copper treasure chest.

The loot Faith received from a copper chest included the Monster Illustration Handbook he had.

"I got a silver treasure chest! A silver treasure chest! My hard work has paid off!"

Su Mo licked his chapped lips, lying on the sand, feeling as if he had drunk a bottle of iced coke in the summer. There was only one word to describe what he was feeling throughout his entire body— 

Wonderful!

After picking up the Japanese Oak Spear and cautiously walking closer, Su Mo picked up the silver treasure chest and quickly hurried back along the way he came from.

Every day, there were three chances to use the Monster Illustration Handbook. Since he had used up his last use to kill the chameleon just now, he could not afford to be careless anymore.

Su Mo traveled all the way back to his base without incident. He locked the wooden door, sat down at his small table, and took out the silver treasure chest.

The body of the chest was silver, shining with a charming silver light. With his breathing next to it, it felt as if there was an air of deadly magic, urging people to open it.

"Open the silver treasure chest."

When Su Mo said those words, a bright light began to burst from the treasure chest, followed by the sound of rolling dice.

[Record]: You have opened a silver treasure chest

[Record]: You have gained Psychic Energy*1

[Record]: You have gained Unknown Pet Egg*1

[Record]: You have gained Energy Bike Blueprint*1

[Record]: You have gained 500ml of mineral water*2

[Record]: You have gained Dalieba Bread*5kg

"I'm rich! I've struck gold!"

When Su Mo looked at the five differently-shaped items in his inventory, he could not calm down. He wished he could go out and find more chameleons to fight for 300 rounds.

Putting aside the food and water for now, Su Mo fixed his gaze on the three items that were taken out in order and lined them up on the table.

[Psychic Energy]: One of the top clean energy sources, has incredible effects, needs the corresponding design blueprints to be used.

[Unknown Pet Egg]: Player needs to put a drop of blood on the eggshell to hatch an unknown pet.

[Energy Bike Blueprint]: Can start when any type of energy is fed into it, including but not limited to food, wood, gasoline, crude oil, psychic energy...

"I can't believe this is the fabled psychic energy that countless scientists on earth have researched again and again..."

When Su Mo toyed with the energy block about the size of a peach in his hand, he suddenly gained additional knowledge of this world.

As the top clean energy source, not only had scientists on earth proposed the scope of application of psychic energy, but they had also pointed out the powerful aspects that came with it.

Fueling something with psychic energy was equivalent to an enchantment and most people would have difficulty comprehending how it worked when it was used on any item.

Although its effect was unknown for the time being, there was at least one technological prototype for future development.

Unfortunately, before the doomsday, the idea had been locked away in the research institute's top-secret laboratory, the stack of research and calculation papers ten meters high.

If the current application of psychic energy was really the same as how it was described as per the results of scientific research on earth, that would mean...

When Su Mo thought of that, he focused his attention, called out to the system internally, and observed his shelter as a whole.

[Personal Shelter]

Owner: Su Mo 

Space: 100㎡ 

Level of Integrity: 100%

Facilities: Wooden bed, wooden chair, wooden table, miniature well water extractor

Introduction: An average, simple, and crude shelter with basic survival facilities. Food will be your current pressing problem.

First upgrade option: Psychic Energy Shelter ????? , required survival points (5000000)

"Unbelievable...there's actually an upgrade option. I just need 5000000 survival points or I can use 5000 psychic energy crystals..."

Su Mo could not help but exclaim in shock.

After all, during his first time detecting an upgrade, there were no upgrade options for his shelter.

Now that he had a psychic energy crystal in hand, the upgrade option for the shelter immediately appeared.

In terms of the psychic energy's development potential, once the shelter was upgraded into a psychic energy shelter, the shelter would essentially be something like a living creature, with terrifying disaster-resistant abilities.

It would probably be possible for the shelter to even be upgraded into an outer space shelter so that the player could travel to the sun for a hot shower.

But of course...

It was too soon to talk about those for now.

That was why Su Mo focused on his sole gold mine—his well water extractor.

[Miniature Well Water Extractor (Normal)

Current efficiency: 2000ml/day

First upgrade option: Upgrade well material, increase sealing function and water purification function. Drinking water freshness time will be greatly extended. Required survival points (200).

Second upgrade option: Increase depth of well, improve water extraction efficiency. Required survival points (300).

Third upgrade option: Leveling up with psychic energy option. Significantly improve water production efficiency, enhance water purification efficiency, long-term collection of drinking water, small chance of physical strengthening. Required survival points (1080).

Comment: A must-have for wilderness survival!

"That's expensive!"

Su Mo was stunned but realized that he had not input his materials.

After he put in a unit of psychic energy crystal, the cost suddenly became 70 points. As for the rest of the materials, Su Mo did not recognize the names of most of them.

After some searching, he found that there were no such materials in the trading market presently.

"I select the third upgrade option!"

The current amount of survival points he had was 88 points and it was enough for the upgrade. Since the well was his current money-making machine, that upgrade was his top priority.

In an instant.

The psychic energy crystal in the hand began to disappear. The next second, a dark blue color lit up from inside the well. Following that, there was a huge transformation on the top of the well.

From the initial greenish-gray stone, it turned into a mixed blue-black color. In addition to that, the material also seemed to have undergone a significant change.

[Psychic Energy Well Water Extractor (Excellent)

Current efficiency: 7200ml/day (300ml/hr)

First upgrade option: quality (3000), efficiency (500), resistance to low temperature (200), water quality (5000)...

He hauled up the water from the top of the well.

The initial clear well water had taken on a slight blue gleam that was visible to the naked eye.

`

Even the introduction had changed.

[Psychic Energy Water]: Has a mild healing effect and long-term consumption can strengthen the body.

After Su Mo tried a sip, he was surprised to find that not only had the property changed, but the taste was also very different.

He realized that the plain water had a full-bodied taste like Maotai from earth.

A mild sweetness blossomed on his tongue, and there was a fragrance caressing his lips and teeth. Before this, his throat was parched and slightly inflamed, but after a sip of psychic energy water, he suddenly felt a lot more comfortable.

"Sure enough, the addition of psychic energy brings a touch of mystery to science! And with a water production of 300ml an hour, this is a great start!"

After he set the water bucket down to collect more water, Su Mo examined the last two items before stowing them away.

Although the current drinking water problem was solved, he still did not have a steady source of food. He prayed that the pet he got was a small one. If he got a big beast that required dozens of catties of food every day, he feared he might not be able to afford to feed it.

As for the energy bicycle, although he had the blueprint for it, Su Mo took one look at the complicated material requirements and immediately scrapped the idea of making it.

It was incredibly convenient as even a unit of wood could be converted into power...

However, since it involved material conversion technology, it was much too complicated.

"The first order of business is to solve the safety and ventilation problem for my base. It would be best if I could also solve the drainage problem in one go."

After Su Mo made up his mind, he began to plan the transformation for his base under the firelight.

Since there were two bottles of 500ml water in the silver treasure chest, it proved that drinking water had high purchasing power.

That was why using psychic energy water to purchase supplies would be a good way to rapidly develop his base.
