Survival: Fighting floods from a thatched hut.

Then he led the four little ones up the stairs.

The area of the second floor has also expanded a lot, and like the first floor, it is also 400 square meters.

The second floor, which was originally a bit crowded due to several buildings and a large amount of furniture, seems very spacious after expanding nearly twice its size.

Going up to the third floor, he found that the area of this floor was not right, it was only half of the first and second floors.

At the same time, he saw a door on this floor.

When you open the door, you will see a balcony based on the roof of the second floor. Except for the north side, there is space on three sides, which is a total of 200 square meters.

He didn't expect that after the Five Elements Shelter was upgraded to level 4, the atmosphere of life would become so strong.

They actually reserved such a large balcony for him. When the colorful flowers grow more, he will plant the balcony full of flowers and cosplay as a literary young man.

Looking at the four excited little ones, Zhang Chi called them over.

"We'll live on the third floor from now on. Go move all the furniture up here!"

The four little ones happily agreed and sat on the edge of the second-floor balcony, watching the chirping animals below.

He felt a little emotional, this family is getting bigger and bigger.

Looking around the shelter, he suddenly realized something was wrong.

Looking carefully at the walls around him, he found that the upgraded walls seemed a bit too thick.

He jumped onto the roof and looked around, and found that the thickness of the courtyard wall was not only one meter, but also extended outward in several places to form platforms.

Especially the corners of the four walls, which extend outwards a considerable area.

what?

What are these places used for?

It looks like the space is reserved for loading city defense equipment.

Speaking of which, the current courtyard wall is eight or nine meters high and one meter thick. It is not an exaggeration to call it a city wall.

But in all this time, he hasn't seen any city wall defensive buildings.

Could it be another level 3 shelter construction blueprint, an item that can only be obtained after reaching a certain level?

I guess that's the case.

Otherwise, it doesn’t make sense for so many platforms to suddenly appear. We can’t just let him repair it by himself, right?

Go back and open a few treasure chests and try.

Open the survival manual.

He planned to first look at the conditions for upgrading the Five Elements Shelter to level 5 and its new capabilities.

【Five Elements Shelter

Level: 4

Grade: Excellent

Function: Quick recovery, five elements convergence, five elements blessing

Expansion building: ...omitted.

Affiliated Shelters: 3/10.

Shelter members: 0/5.

升级条件：求生者卓越级、卓越级木材96/8000、卓越级石头14/12000、卓越级钢锭119/5000、卓越级玻璃0/0、精良级秘银0/2000、卓越级精金0/1000、极致级紫金0/500、极致级灵石：金50/100、水120/100、木10/100、火10/100、土10/100、极致级及以上建筑9/10、附属庇护所：金0/1、水0/1、木0/1、火0/1、土0/1。

Evaluation: A miraculous level 4 shelter, it not only has a defense capability far superior to its peers, but also has a much higher potential for defensive counterattacks.

It also has magical abilities such as excellent fast recovery, excellent five elements gathering, and excellent five elements blessing.

But its upgrade conditions are also unprecedentedly expensive. 】

When he saw the upgrade conditions clearly, Zhang Chi subconsciously covered his heart with his right hand, and a mask of pain appeared on his face.

Isn’t this too expensive?

This time, he no longer had the confidence to say the word "okay".

Not to mention anything else, the amount of wood, stone and steel ingots alone was enough to suffocate him.

This is a full 25,000 units of excellent-grade basic materials!

If ordinary materials are used to synthesize, 1 unit of excellent grade will take 111 minutes.

Even if he had three synthesis rooms, it would take a long time to complete them.

Even if we switch to high-quality materials for synthesis, we can only synthesize more than 420 units of excellent materials a day.

It would take at least two months to collect these 25,000 units.

Putting aside the time, the amount of spirit stones needed to purchase these materials is an astronomical figure.

He made a rough estimate in his mind and found that it would take 50,000 units of high-quality spirit stones to purchase high-quality materials.

If you don't care about the time and use high-quality spirit stones to slowly synthesize it, it will still cost 20,000 to 30,000 fine-grade spirit stones.

There are only more than 20,000 spirit stones in his small treasury.

It may seem like it’s enough if you save a bit, but besides these three basic materials, there are a lot of others that haven’t been counted!

Just to obtain 5000 steel ingots, you would need more than spirit stones.

He thought that upgrading from level 4 to level 5 would be expensive, but he never thought it would be so expensive!

It seems that we can only purchase high-quality and high-quality materials at the same time and combine them together.

After calming himself down, he looked at the other materials and was a little surprised when he saw the glass.

What does 0/0 mean?

After checking the details, he found that it doesn't matter whether he has excellent grade glass or not.

If you upgrade and add enough windows, you can replace all the windows with glass.

If you don’t add anything, just keep it as it is.

Continuing to look at the other things, he had already guessed about the ultimate grade purple gold.

It is estimated that this material is used to build an ultimate altar, and is of the same sequence as refined gold and secret silver.

500 units of ultimate-grade Five Elements Spirit Stones were also within his expectations.

But the last five subsidiary shelters made his heart skip a beat.

Gan!

Is it really what he thinks?!

After checking it out, Zhang Chi let out a long sigh with a blank expression on his face.

He suddenly felt that it would be fine if he didn't upgrade to level 5.

The conditions for this upgrade are really too outrageous!

The other materials are fine, but five level 4 auxiliary shelters of excellent quality or above are actually required.

He could endure this alone by gritting his teeth.

But it actually requires that these five shelters must correspond to the five elements.

If the details interface had not provided the construction drawings of shelters for gold, water, wood, fire and earth respectively, he might not have been able to collect all five types of shelter construction drawings in his lifetime.

Tired, destroy it.

With the idea of easing his mood, Zhang Chi looked at the new abilities of the shelter.

When he saw the name Wuxing Jiazhi, he had some guesses in his mind.

【Five Elements Blessing

Effect: Consume the five elements energy of the shelter or a number of five elements spirit stones to bless the props with the five elements.

Equipment with the same name have the same blessing effects, which are adaptive and cannot be manipulated manually.

Note: After the energy is exhausted, the blessing disappears. Do not use the opposite attribute to bless (such as using fire to bless water equipment), otherwise it will cause a high probability of equipment damage. 】

The effect is indeed similar to enchantment.

He originally thought that the five pieces of equipment would not only become weapon spirits, but would also become the guardian artifacts of the shelter.

In the end, after all this time, there were only five demonstration items.

He took out the blessed guardian stone tablet and Blue Lake Jade and put them on.

Then he punched his left hand with his right hand.
