158: Second upgrade option! Level 10 Shelter!

[Buzz!]

Congratulations! Your Shelter has successfully upgraded to Level 10!

The Shelter advancement quest is now open!

Your Shelter faces the second advancement choice!

[Choice One: Biological Shelter.] After advancement, your Shelter will evolve into a biological entity, gaining the ability to move around, allowing you to explore more distant areas.

Requirements for Upgrade: 100 million mist crystal stone, 100 million mist crystal iron, 100 million mist crystal wood, 1 million god-tier elemental stone, 5 billion god-tier monster crystal, 1,000 god-level ore vein heart of any attribute, 10 units of space-type materials, 1 shelter advancement decree.

Note: For this upgrade, you can additionally invest 1 to 10 other materials, with a quantity of 1 million units.

These materials will provide your Biological Shelter with different Talents and powers.

[Choice Two: Barrier-level Shelter.] After the upgrade, your Shelter will possess a barrier shield, granting you stronger defensive power and concealment.

Requirements for Upgrade: 100 million mist crystal stone, 100 million mist crystal iron, 100 million mist crystal wood, 5 billion level 0 monster crystal, 100 million level 1 monster crystal, 1,000 god-level ore vein heart of any attribute, 10 units of space-type materials, 1 shelter advancement decree.

[Note: shelter advancement decree can be obtained through the mist sacrificial altar, secret realm exploration, Mist Survival Battle, Mist Shop, Trading Center, hunting field BOSSes, opening chests, and other methods.]

[Note: Before advancement, please upgrade your Shelter's defensive city wall to the highest level.]

Su Lie looked at the information that appeared before him, his eyelids twitching: "When my Shelter upgraded to Level 5, there was an optional upgrade! Now that it's Level 10, there's another advancement upgrade!"

"It seems my type of Shelter gets a major upgrade every 5 levels!"

He deduced some intelligence from this.

Following this, Su Lie finally looked at his Shelter.

After several consecutive upgrades and Enhances, his Shelter could only continue leveling up after completing this advancement quest.

[Upgrade: Requires the completion of the second advancement quest to continue upgrading.]

[Description: Your Shelter has reached the highest level for the current stage.

Although the defensive city wall still needs improvement, among the current Survivors, it is a Shelter that other Survivors can only look up to!

However, in the Mist World, your Shelter is still as fragile as toilet paper!]

"Hoo! At Level 10, the main building and the basement hadn't reached the maximum MAX, but after Enhance, they immediately reached the highest building height and area!"

Su Lie exhaled, excitedly looking at the Shelter panel.

Now, the Shelter's main building had expanded again, becoming a 10,000-square-meter square structure.

The Watchtower had already reached its maximum value at Level 9 and could not be further upgraded in subsequent levels.

Based on Su Lie's observation of the Mist Defense Value, he found that every time the value exceeded one million, the Mist Safety Level could be increased by 1 level.

In these three consecutive upgrades, the only thing that hadn't changed was the Comfort Level.

Clearly, this required Su Lie to make internal modifications to the Shelter's main building.

In its current state, there was simply no way to improve the Comfort Level.

In this upgrade, Immunity to Pathogens, Immunity to Glare, Spatial Stability, and Advanced Earthquake Resistance were new special effects gained when the Shelter was upgraded and Strengthened to Level 9 and Level 10.

Among these dozen-plus special effects, the Exorcism Special Effect stopped increasing its value once the exorcised monster level reached 50.

Meanwhile, the Suppression Special Effect still increased its effect by 5% with every level up, just like normal.

What excited Su Lie the most was that the diameter of his Shelter had grown to 10 kilometers across.

This had already become a city.

Even in ancient times, it would be one of the largest cities.

The expansion of the Shelter courtyard area meant that Su Lie could construct more Vegetable Garden, spiritual fields, and Paddy Field.

It meant Su Lie could have a larger active space within the Shelter, allowing him to plant anything he wanted to cultivate.

He could even cordon off a separate area for military training.

Thinking of this, Su Lie couldn't help but smile.

RUMBLE!

Just then, a violent roar came from around the Shelter.

*Clatter! Clatter!*

A Little Skeleton of the Black Tortoise Army ran into the Shelter.

It solemnly knelt at Su Lie's feet and began chattering wildly.

Su Liya, who was nearby, froze and immediately stopped kneading her hands.

She solemnly translated to Su Lie: "Master! The squeaking of the Soul Spirit Tree is attacking our walls, and it is shouting that it wants to meet and negotiate with you!"

"Huh?" Su Lie was startled.

He suddenly stood up: "Let's go! Go look at the city wall!"

Saying this, he quickly walked toward the entrance.

The entrance, which previously only took twenty steps to reach, now took Su Lie nearly a hundred steps.

Because he was walking quickly, he didn't notice anything.

When he opened the door and walked outside, Su Lie suddenly stopped in his tracks: "Holy crap!"

He had overlooked a problem.

While the Shelter upgrade had indeed brought enormous growth, the distance from the Shelter to the city wall had consequently increased by a full 4,900 meters.

Walking from here to the base of the city wall would likely take quite some time.

BOOM! RUMBLE!

Moreover, the roaring sound coming from outside the main entrance made people panic.

*Whoosh!*

Su Lie moved his mind, directly pulling out the children's scooter.

After having Su Liya stand behind him and hug him, he initiated a glide, starting the scooter.

The scooter sped along at 1,000 meters per second.

It took nearly 5 seconds to reach the base of the city wall.

Standing beneath the city wall, Su Lie felt exceptionally small.

However, although the Shelter had gotten bigger, the glass sunroom roof on the dome had also expanded along with the Shelter.

RUMBLE! RUMBLE!

At this point, the roaring sounds became exceptionally clear.

Su Lie quickly walked up the city wall.

The moment he appeared, the branches outside the city wall, which had been whipping the wall, instantly stopped moving.

Su Lie only saw it when he walked to the crenellation of the city wall.

The Shelter's city wall was already embedded in the city ruins.

In the ruins, numerous branches, condensed from blue light points, were slowly growing.

The entire Oasis area where the Shelter was located had been completely encompassed within the Shelter.

The Gravity Oasis area had therefore completely disappeared.

The spatial light screen that distinguished the gravity zone from the non-gravity zone was also gone.

At the same time, a notification from the mist rule appeared before Su Lie...
