"boom"
A tremendous impact came from beneath her feet, and Lin Ruo almost lost her balance.
She swept her mental energy across the unfathomable sea once more before quickly withdrawing it.
When she used her spatial domain to teleport back to the fortress, she saw that Afu and Ashou were still standing on the platform, looking at the distant sea with a hint of worry and fear in their eyes.
But when they saw Lin Ruo appear on the platform, they instinctively ran to stand in front of her. This obvious protective posture made Lin Ruo's eyes crinkle. She never doubted Afu, Ashou, and Aliu's desire to protect her.
Recalling their somewhat agitated behavior during the previous rat and insect swarms, Lin Ruo walked over and gently patted their thick forelegs. "It's alright, don't worry, I won't let you get hurt."
Ah Fu and Ah Shou lowered their heads and placed their big noses in Lin Ruo's palm. At this moment, Ah Liu's willow branch also stretched out and wrapped around Lin Ruo's waist, seemingly giving Lin Ruo confidence as well.
Lin Ruo calmed them down before leading them back to the fortress.
With anxiety in their hearts, the three of them seemed to eat less than usual, which Lin Ruo noticed and kept in mind.
She could have put them in the space during the earthquake and tsunami, but they couldn't live in anxiety for the remaining two days.
Even if they know they will be put into the space, they will still be anxious because they know she cannot enter the space, and they will worry about her.
In order to give them enough confidence, Lin Ruo decided to start upgrading the fortress tonight.
They and the fortress were stored in the space, leaving only a huge pit in the original location.
To ensure her safety when her spiritual energy entered the space, she took out Wei Su from the space and placed it outside the pit in the fortress.
She entered the micro-settlement, which was still warm and cozy. It was protected by a shield made of underground minerals from the space, so she was safe and sound. Only then did she sink her spiritual energy into the space.
Since we're upgrading the fortress, we need to improve all its weak points. After the spatial ability is upgraded, the crystal core shell should be able to melt, so bulletproof glass will be obsolete.
She took out a crystal core shell from the static space, used her mental power to control the spatial ability, and rapidly increased the temperature around the crystal core shell until it reached the upper limit of 5000 degrees before the upgrade!
The temperature continued to rise, and the crystal shell, which was exposed to high temperatures, began to melt slowly until the temperature reached 6000 degrees Celsius, at which point the crystal shell completely melted into liquid.
Once he was certain that it was feasible, Lin Ruo used his mental power to take out all the crystal shells in the static space and melt them into liquid at high temperature, then set them aside.
After that, she first moved tons of underground ore out of the static space and smelted it at high temperatures. Pile after pile of underground ore was added to these high-temperature areas, where liquid black jade crystal liquid was continuously produced.
Then she manipulated the liquids to slowly take shape. The black liquid gradually formed the shape of a new fortress. Then she added the liquid from the crystal core shell, which gradually formed the shape of a window.
When she built the fortress last time, her mental energy was insufficient, and she had to recover several times. This time, she didn't feel like she was overdrawing at all, which shows how terrifying Lin Ruo's mental energy became after her two breakthroughs.
The dark jade-colored liquid slowly solidified, and the fortress gradually took shape. This time, she used dark jade crystal to build the walls of the fortress, and the walls were 20 centimeters thick. Because dark jade crystal is somewhat transparent, she added a thin layer of bricks made from underground minerals on the outside. This time, she added some pigment to the inside to make the color of these bricks closer to white.
Extreme heat is coming soon, and dark-colored bricks absorb too much heat, so light-colored ones are better.
After laying the bricks, Lin Ruo reinforced the outside with a thin layer of liquid crystal core shell. This time, Lin Ruo worked on more windows, and they were quite large, with plenty of light.
When the hottest period arrives, she can make blackout curtains and hang them up, so it won't be too hot.
Lin Ruo even made sure the gaps when opening and closing the windows were perfectly sealed, using all the crystal shells she had previously used.
The walls of the entire fortress were made airtight, so strong that not only could a tsunami not break them, but even a nuclear bomb could not destroy them!
With this kind of defense, when earthquakes and tsunamis strike, all she has to do is stabilize the fortress; she doesn't need to worry about its safety.
Lin Ruo also made changes to the base of the fortress, increasing its thickness to 5 meters and maintaining its 2000 square meter size, all made of black jade crystal.
To enhance the fortress's stability, she added over a dozen intersecting I-beams, totaling more than 200 meters in length, to the base. Once the soil was buried on top, this maximized the fortress's grip.
To accommodate Afu and Ashou's rapidly growing physique, Lin Ruo made the fortress 45 meters high, a full 20 meters taller than the original. This way, even with Aliu's height, the fortress could be completely covered without affecting Afu and Ashou's activities.
Besides, if the overall area of the fortress remained unchanged, adding too much would make it impossible for A-Liu's willow branches to cover it up.
At the top of the fortress, Lin Ruo had reserved two slots for placing crystal energy particle cannons.
Considering that extreme heat would soon arrive, she also reserved air conditioning ducts, as well as brackets and fences for placing air conditioning units outside the fortress, all of which had latches that could be opened.
After completing the fortress smelting, Lin Ruo began to improve the protective shield. This time, the protective shield was also made of black jade crystal, with a thickness of 40 centimeters. When covering the entire fortress, Lin Ruo tested it with water flow and only felt relieved after finding that there was no water leakage.
Looking at the fortress he had built in the sky, Lin Ruo felt extremely satisfied.
