"Young lady, the bus is about to leave, are you getting on or not?" the bus driver urged Ye Jiu, who was standing in front of the bus stop.

Feeling dizzy and lightheaded after arriving, Ye Jiu waved her hands repeatedly, "No, thank you. I just remembered I forgot to bring something. I'll wait for the next shift."

As the bus drove away, Ye Jiu leaned against the bus stop sign, sorting through the original owner's memories.

This is a future interstellar world where, during a long process of evolution, people's physical abilities have been greatly improved, and they have also discovered the existence of mental power.

Mental strength is innate; whatever level you are at birth, you will remain at that level thereafter.

As the world has developed to this point, humanity is no longer the sole superpower. Suddenly, an insectoid race appeared in the universe, eyeing Earth with predatory intent. To combat these insects, humanity invented mechs, and mental strength is the key to determining whether one can pilot a mech.

The higher one's mental strength level, the better the mech one can pilot. An S-class mech and a skilled pilot can single-handedly clear out a small Zerg nest, demonstrating terrifying power.

However, not everyone possesses mental strength; ordinary people still make up the majority. Furthermore, since mental strength is heritable, most children born to parents with strong mental strength also possess strong mental strength. It is rare for children whose parents lack mental strength to mutate and defy fate.

Due to their scarcity and the urgency of the Zerg invasion, most people with mental abilities are carefully cultivated by the state and become the upper class of society. Since mental abilities can be inherited, those with mental abilities only marry those with mental abilities, resulting in a near-rigid class system and a severe gap between the rich and the poor.

Therefore, apart from children born to people with spiritual abilities, ordinary people will not come into contact with spiritual ability tests or mechs.

So, none of this has anything to do with Ye Jiu. She is currently an ordinary 15-year-old junior high school student who will soon be going to high school. Her father passed away when she was born, and her mother was paralyzed from the waist down in a car accident when she was 10. With the current level of medical technology, it is theoretically possible to improve her quality of life through exoskeleton devices and other equipment, but her family is poor, and her mother can only lie in bed all day long.

She had no relatives. The original owner of this body became the pillar of the family from the age of 10, picking up garbage to support the family while attending school, and trying her best to finish her homework at school and do housework and take care of her mother when she got home.

Despite her hard work, her grades didn't suffer; on the contrary, she consistently ranked first in her grade and received the school's scholarship. It was thanks to the scholarship that the two of them didn't starve.

When she was 12, she was sponsored by Huai's family because of her family's financial situation and academic performance. They gave her a sum of money every year, and she no longer needed to pick up garbage while attending classes. Without the financial pressure, she studied even harder and took better care of her mother. Unfortunately, her mother passed away when she was 14.

Now she's all alone...

So she decided to board at school in order to improve her grades. She was grateful for the Huai family's support and hoped to work for their company after graduation so that she could find an opportunity to repay them.

And now the opportunity to repay them has arrived.

The young master of the Huai family was injured in an accident that left him disabled in both legs. He stopped going to school and shut himself in his room. The Huai family's parents were afraid that something would happen to him, so they wanted to find someone who was about his age to take care of him, play with him, and comfort him.

Ye Jiu, who was 15 years old and had excellent grades, and had experience in taking care of her paralyzed mother, became the best candidate in their eyes.

Today, she is going to take a car to Huaijia to report for duty.

After sorting through her memories, Ye Jiu stopped, turned around, and went to the small supermarket behind the bus stop to buy candy. No teenager could resist candy, right?

With just two star coins, Ye Jiu could buy a whole bag of lollipops.

She could never spend all the money her family gave her each year, especially after her mother passed away; she saved all the extra money.

The little girl was too frugal to spend money and didn't even treat herself to a few good meals. She just passed away from a heart attack, and it was precisely because of her death that Ye Jiu was able to be inserted into the system.

Ye Jiu unwrapped a lollipop and put it in her mouth. She looked up at the sun; it was a beautiful day.

"Buzz...buzz...connection successful." The familiar electrical sound rang out. Ye Jiu rolled her eyes, waiting to hear what kind of nonsense this system would spew this time. Every time she saw it, nothing good ever came of it.

"Congratulations on successfully entering the world."

Ye Jiu (coldly): "I should die even if I fail to get in."

The system choked for a moment, then remained silent for a long time before speaking again, "This mission world is special; I'm here to give you a cheat code."

Excited? Trembling? This system is incredibly useful!

The system was so excited inside, but all it got in return was a cold "Oh, and then."

system:……

Damn it, this isn't the script they had in mind!!!

When the system still didn't speak, Ye Jiu couldn't help but urge, "Spit it out already, we're in a hurry."

"Ahem." The system cleared its throat and solemnly announced, "The cheat code this system is giving you is... mental energy management!!"

Ye Jiu, who was not a native, did not understand the value of this ability and remained unmoved.

The system screamed, "Aaaaaah! Why aren't you excited?! Do you know what this means?!"

"Then tell me."

"In this world, excessive use of mental energy leads to mental chaos!! This world has never developed a solution! People with mental chaos can only wait to die!! But I! I'm giving you a cheat code!! That can cure this!" The system's voice grew louder and louder, and it felt increasingly proud of itself. Wow, it's amazing that it can tailor a cheat code to the tasker based on the world!

Ye Jiu raised an eyebrow. "So, you mean I'm the only one in the whole world who can save them?"

"That's absolutely right!" the system said, enunciating each word clearly.

So get excited! Scream! Worship me!

"oh."

With a "crack," the system's heart shattered. In its mind, it angrily picked up the fragments of its own heart and cursed, "You don't know what you're missing, bah!"

Remembering his few remaining consciences, he continued to explain to Ye Jiu, "Your current body only has C-level mental strength, but you know, mental strength is predetermined. The cheat I'm giving you allows you to absorb mental strength that others can't handle while helping them manage their mental strength, turning it into your own power and raising your own mental strength level."

"Mental chaos is essentially because the body cannot withstand mental energy. When mental energy is overused, it rebounds and recovers in large quantities. The human body cannot withstand this excess power in a short time. The mental energy with nowhere to go will damage the body's functions. Once the body's functions are damaged, it will be even less able to withstand so much mental energy, thus creating a vicious cycle."

"Mental energy damages the body, which the body cannot withstand, and continues to damage it until the heart is destroyed, leading to death. Therefore, it is said that once mental energy is in chaos, one can only wait to die."

"Currently, the world's research on mental power hasn't reached this level, so, hehe, you are the savior!"

Ye Jiu guessed that if the system had hands, it would keep patting her shoulder. She was so excited; anyone who didn't know better would think that this cheat code was its own...

Even though it was given to me by it.
