Amidst the swirling snow, a layer of ice suddenly appeared, quickly enveloping the fortress on the mountain peak and rapidly spreading outwards. The air near this layer of ice was visibly distorted, demonstrating just how low the temperature of the ice had become.

Ah Liu and the others hid in front of the mutated forest, their hearts filled with excitement. The appearance of this ice indicated that their master's superpower was upgrading, so even though the ice was colder than before, they found it extremely pleasing to the eye.

But after only a few seconds of looking at them, they all retreated in unison. The temperature of the ice was too low; even standing dozens of meters away, they couldn't bear it and immediately hid in the mutated forest.

Old White was even more glad that he was wise. Luckily, he had his owner transplant him here before, otherwise he would probably be frozen into an ice sculpture by now. He was the only one in the house without legs, and even running was difficult for him.

Knowing that things were going smoothly, they dispersed to different locations to guard the fortress, preventing anything from disturbing Lin Ruo. Although nothing could break through the ice, they still stood firm and did not yield an inch.

Time passed day by day, the sky darkened and then brightened again, and seven days passed in the blink of an eye. The layer of ice that enveloped the fortress did not dissipate during these seven days.

Lin Ruo herself was frozen in the ice inside the fortress. If you looked closely, you could see bursts of white energy flowing into Lin Ruo's body through the ice. This energy all belonged to the fruit that Old Bai had.

The ice had already appeared the moment my mental energy entered those white fruits to absorb energy.

When the last trace of white energy was completely absorbed by Lin Ruo, who had been sitting in the ice for seven days, he suddenly opened his eyes. The ice outside immediately shattered and turned into starlight, which entered Lin Ruo's body.

Lin Ruo had already absorbed all the crystal cores in the training room. The energy she needed for this upgrade was more than she had anticipated. Upgrading her spatial ability alone had already consumed all the crystal cores. If it weren't for these white fruits, she probably wouldn't have been able to upgrade both abilities.

She was sitting in a pile of crystal shells, her body covered in a layer of black filth, and a foul stench filled the air. Lin Ruo's brows were furrowed tightly. This time, the amount of impurities extracted from her body was twice as much as during her last upgrade, which must be due to the effects of those fruits.

Normally, the more impurities are expelled from the body, the better. However, because these impurities had not been cleaned for a long time, they had all dried on Lin Ruo's skin, making her very uncomfortable.

With a thought, streams of water appeared on her body, flowing slowly along her skin. The dried grime was quickly dissolved by the water, and soon the clear water turned completely black.

Lin Ruo cleaned herself five times before she could finally get rid of all the filth on her body. She had already taken off her clothes, put them in a bag, and thrown them into the still space.

After washing her body and changing into new clothes, she breathed a sigh of relief, but she still felt that there was a smell in the training room. With a flick of her finger, a large amount of water mist spread into the air. The water mist was still warm and continued to absorb the stench until Lin Ruo felt that there was no more smell in the room. Only then did she condense the water mist into a water ball.

The water ball, along with the others that had turned black, flew into the bathroom and was thrown into the toilet to destroy the evidence.

Lin Ruo stood up, stretched, and her bones cracked as she did so. After the cracking stopped, she felt refreshed.

Her first reaction after the upgrade was to see the results. She used her mental energy to probe her brain and then "saw" the three crystal cores in her mind.

She intuitively felt that although the energy of the crystal core in her mind had increased several times, its size was smaller than before, except for the newly appeared crystal core, which was slightly larger.

It seems that what she felt before wasn't just her imagination; her mental power has indeed mutated, and she has become a mental power user.

Thinking about the new crystal core that had appeared in her mind, Lin Ruo curiously reached out to touch it, and unexpectedly, a third crystal core was generated under such circumstances.

The crystal core was colorless and transparent, and it shone faintly in Lin Ruo's mind. She had always known the difference between her mental power and that of those mental ability users.

Previously, her mental power was intangible and formless, and could only be used to control superpowers or for exploration and early warning. But now it's different. Her mental power has also become substantial. She looked down at her hands and an invisible energy enveloped them. Her eyes curved into a smile. So this is what mental power feels like to the touch—a sticky, gelatinous texture that is soft and pleasant to the touch.

She glanced to the side and saw the dumbbells on the table wrapped twice with her mental energy and delivered to Lin Ruo. She reached out and took the dumbbells, which weighed several tens of kilograms, feeling their weight so real.

The smile on her lips grew wider and wider. From then on, her mental power could not only be used to control supernatural abilities, but also to attack. Starting today, she would study how to use mental power to attack, which was different from her previous water and space-based attacks.

This upgrade was a pleasant surprise for her; she had never even considered it before.

Before she could even check the changes after upgrading her water and spatial abilities, she sensed the movement. Afu and the others had returned. With a swift movement, a black shadow flashed by, and she was already in the living room.

In less than a second, she moved dozens of meters. This time she didn't use teleportation; she relied solely on her physical abilities. This was even with her strength restrained; if she had used her full strength, the distance she moved would have been even greater.

The white fruit this time has indeed improved her physique a lot, to the point that she herself is now somewhat unaccustomed to it.

The effect of the rapid movement was the same as when she used teleportation after she first obtained the spatial domain. This speed, comparable to teleportation, is already considered the ultimate.

The few animals in the living room didn't seem too surprised by Lin Ruo's sudden appearance. They circled her big nose without moving, as if they wanted to see how she was doing. Lin Ruo couldn't help but feel glad that she had washed off all the dirt on her body. Otherwise, the scene she was seeing now would not be so harmonious. They would probably have run far away in disgust.

Taking back her joke, Lin Ruo said directly to A Liu, "A Liu, shall we have a spar?"
