After calculating the time, seven days is simply not enough.
[Host, the system has met the conditions for upgrade again. Do you want to upgrade? 】
Perhaps sensing Cen Li's thoughts, the system's voice sounded at the right time.
Hearing this, Cen Li was overjoyed and quickly asked, [When the system is upgraded, will the space classroom be upgraded as well?]
【Will do.】
So Cen Li looked at the points and said with certainty, [Great, let’s upgrade!]
She has done a lot of things recently. Although she doesn't pay special attention to rewards, the system still only gives rewards.
Especially for the successful development of C-ring and the extraction of graphene, the rewards are very rich.
Only for the nuclear power plant, because it has not been built yet, the reward is delayed.
Just like the previous specific drugs for depression and Alzheimer's disease, she can only get feedback after they are officially developed, put on the market, and make real contributions.
For her, it is equivalent to an investment.
[The system is being upgraded, please wait!]
After Cen Li finished speaking, the system began to be upgraded. Now even the space classroom could no longer be used, so she simply fell into a deep sleep.
She didn't know how long she slept before her consciousness finally reappeared in the space classroom.
Then she discovered that something completely changed inside.
Becoming more intelligent, especially the virtual laboratory, any experiment you want to do can be directly produced here!
【Hello host, I finally meet you.】
Suddenly, a small white cat with blue eyes appeared in front of him.
[You...you are the system?]
[Yes, this is the physical appearance that I transformed through the host's preferences, so that I can communicate with you more concretely. 】
Cen Li was shocked. After the system was upgraded, it became even more advanced.
Soon, she looked at the system's furry little body and moved her fingers, "Then, can I touch you?"
【Um?】
The system is a little confused.
The next second, the entire cat body fell into Cen Li's arms, and the fur on the body was stroked continuously, [Wow, even the touch is so real, your fur is so soft!]
The system twisted its body unaccustomedly, "I am the system, not a real cat, please don't treat me like a cat!"
Hearing this, Cen Li rolled his eyes and imagined for a moment, then a cat teasing stick appeared out of thin air in his hand.
Put it in front of the system's little white cat and shake it.
【Meow, meow~】
As soon as he saw the cat teasing stick, the little white cat was immediately attracted and stretched out his paws to stand upright and play.
When Cen Li saw it, she raised her eyebrows and said, "Look, it's just a cat~"
【……】
The entire cat body of the system froze for an instant, and immediately retracted its claws, controlling its instinct and saying, "This... is just a setting problem, I can just change the setting."
Hearing this, Cen Li put away her teasing stick and stopped teasing the system. "That's such a pity. Forget it, I won't tease you anymore. What is the time flow rate in the space classroom now?"
[One hour outside, 12 hours inside the space classroom.]
[hiss…]
This time, Cen Li was really shocked.
In this way, if she sleeps eight hours a night, she can study day and night for four days.
Moreover, you must know that you will not feel tired when studying in the space classroom, and you will always be energetic. It is equivalent to how long you study, how much content you receive.
In this way, there are still seven days until Grandpa Bai's birthday, and she can study in the space classroom for almost a month.
