72: Thorn Walls! Please use the gate!

"What is this?"

Su Lie carefully looked at the Shelter's panel, his mood excited and surging.

He could finally build more spirit fields and vegetable fields for cultivation.

After the upgrade, the Shelter not only gained a courtyard.

Even the Garden and the basement, which were listed in the special effects, were integrated into the Shelter.

"The Garden is still an Invisibility Garden, and it doesn't take up the area of the courtyard! I am very satisfied with this point!"

Su Lie walked into the Garden in surprise, finding that it was still the same.

One could still only enter the Garden through the Shelter's main building, and not from the courtyard.

Furthermore, the courtyard could not see anything within the Garden.

With this upgrade, the basement was also expanded to the same size as the Shelter's main building.

Su Lie could place more mineral veins.

And the Watchtower, as an auxiliary structure, also successfully merged with the Shelter.

Its basic information could be viewed directly through the Shelter's panel.

"However, the toilet and bathroom, as well as the room for the Little Skeleton, and the rooms for Liya and Keqing, are not marked on the courtyard panel!"

Su Lie also made some guesses based on the panel: "Perhaps all the facilities inside the Shelter can be freely constructed by me!"

He looked at the other attributes: "The city wall is 10 meters thick, which means we can stand on the wall to defend!"

"I need long-range archers, and I need more Little Skeletons!"

Su Lie identified the Shelter's shortcomings.

He must refine as many Little Skeletons as possible.

But where could he find Dried Corpses?

He wrote the problem down.

He then looked at the Special Mark attribute.

"It seems the Mist Phoenix Bird also left a mark, but I don't know who is stronger, it or the Mountain God!"

Seeing this, Su Lie's eyes twitched slightly.

He had thought the Mountain God was stronger than the Mist Phoenix Bird.

Who knew.

The Shelter actually had a mark from the Mist Phoenix Bird.

Obviously.

In the eyes of the Mist Phoenix Bird.

The Mountain God did not seem frightening.

Otherwise, it wouldn't have left a mark.

"Could it be that the so-called deities in this world are just Mist Monsters around Level 50?"

Su Lie made a vague assessment: "The trade fair hosted by the Mist Phoenix Bird at dawn should allow me to find out something, but I don't know if the Mountain God will go there!"

He then looked at the special effects.

This upgrade added a special effect for the defensive city wall.

The purpose of this special effect was to grant the walls of the Shelter's courtyard independent upgrade authority.

Moreover, the special effects for the Garden and the basement disappeared.

This should be related to them becoming part of the Shelter's main structure.

Among these, the Banishment special effect underwent a huge change; it no longer increased the distance over which monsters were banished, but only increased the level of monsters banished, with the distance limited only to the range of the Shelter's courtyard.

Although this ability seems weaker in the short term, in reality, once the Shelter's level increases and the courtyard expands, the current effect will definitely be better than before.

The Invisibility Window special effect is no longer day-and-night hidden; it is now directly an Invisibility window, allowing one to see the courtyard scenery at night, but the outside world cannot see the inside view.

The change in this special effect should be related to the courtyard.

Because of the wall, the windows of the buildings in the courtyard are shielded from view, so there is no need to worry about mutation occurring due to making eye contact with a Mist Monster.

The Suppression special effect increased its Suppression power by 5%.

The other special effects remained unchanged.

Su Lie then looked at the materials required for the final upgrade.

"Upgrading won't be so easy in the future! The resources required to upgrade the Shelter are too much!"

Su Lie sighed.

However.

He was still satisfied with this type of Shelter.

Subsequently.

Su Lie walked out of the Shelter.

He found that there was no Mist in the courtyard.

The Mist was blocked outside the wall, using the city wall as a boundary.

He first climbed onto the city wall to take a look.

He found that the city wall resembled ancient walls in the Dragon Kingdom, possessing not only battlements but also ramparts for ascending and descending the wall.

In the Mist outside the city wall, a large number of scarlet pupils could be seen.

Those were Mist Monsters gathering and wandering in the area one meter outside the courtyard wall.

Su Lie looked at the monsters below and pondered: "If a Shelter crisis happens again, these monsters will truly cling to the wall! The defensive area has expanded!"

The increased size of the courtyard-style Shelter meant a larger contact surface with the Mist Monsters.

This was equivalent to an increase in his defensive difficulty.

If he didn't have enough manpower.

Relying on his fifty-plus Little Skeletons.

It would be difficult to defend!

Su Lie felt a sense of crisis.

He immediately looked at the wall's panel.

[Defensive City Wall]

[Type: Ordinary]

[Level: 1]

[Thickness: 10 meters]

[Height: 5 meters]

[Gate: Iron]

[Defensive Special Effects: 0 / 1]

[Upgrade: 100,000 units of Stone, 100,000 units of Iron, 1,000,000 monster crystals]

[Description: An ordinary defensive city wall capable of defending against common zombies, Dried Corpses, and low-level fierce beasts. Against beings possessing extraordinary power, it is less useful than a sheet of paper.]

"This damn thing even upgrades separately! It consumes too many materials!"

Su Lie curled his lips and muttered with slight dissatisfaction: "If it's this difficult for me, it must be even harder for other Survivors!"

"And this city wall can only have a maximum of 1 Defensive Special Effect! I wonder if the number of special effects can be increased after upgrading."

"Huh! The city wall doesn't have durability or defense values, so it seems to be linked to the values on the Shelter panel!"

"Does this mean that when upgrading the city wall, I can only upgrade attributes other than durability and defense, and those two values won't change due to the wall's independent upgrade?"

As he spoke.

He used his Enhancement Talent on the city wall.

Buzz!

A beam of light flashed.

Under the effect of the Enhancement Talent.

The Defensive City Wall seemed to have undergone some changes.

Su Lie looked at the wall's panel again.

He saw that the wall's type had changed from Ordinary to Magic.

An additional Magic Defense attribute appeared.

[Magic Defense Value: 10,000 points]

A Thorns special effect was added to the defensive special effects.

[Special Effect Thorns: Any non-friendly life that touches the city wall will sustain damage equal to 100 Health Points lost per second, until the target dies or moves away from the wall.]

"Good! With the addition of the Magic Defense Value attribute to this Defensive City Wall, it can now defend against extraordinary attacks! And the materials required for upgrading after Strengthening haven't changed! That's excellent!"

Su Lie's eyes lit up upon seeing this, and he started to Enhance it again.

A prompt from the mist rule jumped into Su Lie's line of sight.

[Buzz!]

[The Defensive City Wall has been Strengthened to its current maximum defensive capacity. Please increase the Shelter's level, or the Defensive City Wall's level, before attempting to Enhance it again!]

He sighed after reading it: "Can I really not use it anymore?"

He tried to Enhance the other attributes separately, but still couldn't.

Seeing that the Defensive City Wall could not be Strengthened.

He then started to Enhance the Shelter.

Buzz!

The entire Shelter glowed with a ball of red light.

After the light flashed.

A prompt appeared before Su Lie again.

[Buzz!]

[The current Shelter has been Strengthened to the strongest state for its current level. Please increase the Shelter's level before attempting to Enhance it again!]

"It's like this again!"

Su Lie opened the Shelter's panel again.

He found that after Strengthening.

Both the Shelter's durability and defense values had increased by 2 times.

Durability became 3 million points, and defense became 2 million points.

The safety level increased from Level 5 to Level 7.

The overall Strengthening of the Shelter could still only affect durability and defense values.

At the same time, an additional special effect was added.

[Special Effect Gate: Any being that wishes to enter your Shelter must follow the process of knocking, receiving the owner's permission, and having the owner open the door before entry is possible.]

"A conceptual type of special effect?"

Su Lie's eyes brightened.

This way, Mist Monsters like the Mist Phoenix Bird that suddenly descend upon the Shelter will be unable to enter the Shelter without Su Lie's permission.

This was a good thing!

"Unless they forcibly break down the door and attack? I also don't know if the Shelter's current durability and defense values can withstand them."

Su Lie's heart sank again, and the sense of crisis within him intensified.

A few minutes later.

Su Lie looked at the empty courtyard, a light flashing in his eyes: "I'll design the courtyard tomorrow! It's getting late today! First, I'll wash the dirt off myself, and then prepare the resources needed for the dawn gathering!"

While muttering.

He returned to the Shelter, holding Su Liya with one hand and Su Keqing with the other. Before he could speak, the two girls were already following him closely toward the bathroom.

As they walked, Su Keqing hesitantly said: "Master! I want to witness the other moves of the 'Ah Wei Eighteen Forms' you mentioned yesterday!"
